In brief
This Baseline Report sets out the current state of the UK’s economic infrastructure and identifies key challenges for the coming decades. The Commission will make recommendations to address these challenges in the second National Infrastructure Assessment, to be published in the second half of 2023. The Call for Evidence has now closed.
Since the first Assessment, there has been progress on some issues:
These include full fibre rollout, electricity decarbonisation, drought resilience, infrastructure financing – through the creation of the UK Infrastructure Bank – and design.
However, in other areas, there is more to be done:
- greenhouse gas emissions from economic infrastructure must reduce further, fast
- asset maintenance issues undermine performance in some sectors
- more than three million properties in England are at risk from surface water flooding
- serious pollution incidents from water and sewerage are unacceptably high
- urban transport connectivity varied and is poor in many places.
Future trends and government commitments will bring new challenges:
- climate change will make it harder to make and keep infrastructure resilience
- nature is declining at unprecedented rates
- the Covid-19 pandemic may lead to long term changes in where people live and work
- new and emerging technologies will offer opportunities across sectors.
Delivering on these challenges will require bold action, stable plans and long term funding.
The Commission has identified nine key challenges for the second Assessment:
- all sectors will need to take the opportunities of new digital technologies
- the electricity system must decarbonise fast to meet the sixth Carbon Budget
- decarbonising heat will require major changes to the way people heat their homes
- new networks will be needed for hydrogen and carbon capture and storage
- good asset management will be crucial as the effects of climate change increase
- action is needed to improve surface water management as flood risk increases
- the waste sector must support the move to a circular economy
- improved urban mobility and reduced congestion can boost urban productivity
- a multimodal interurban transport strategy can support regional growth.
The Commission has welcomed views on these key challenges in response to the Call for Evidence (now closed). The Commission will also hold events during the Call for Evidence period and in the run up to the second Assessment.

Foreword
To build a long term vision for the infrastructure of the future we need to understand where we are today.
This Baseline Report surveys the state of our national systems of digital, energy, flood resilience, water and wastewater, waste and transport.
It enables the Commission to identify the biggest questions about the UK’s readiness for the challenges and opportunities of the future, and to review developments since we published the first ever National Infrastructure Assessment in 2018.
We acknowledge areas of tangible improvement in recent years, contributing to generally good levels of public satisfaction with national infrastructure services. We highlight the progress of the rollout of gigabit-capable broadband, major steps in electricity decarbonisation and the establishment of the UK Infrastructure Bank as examples.
But major challenges remain. Carbon emissions from economic infrastructure must reduce further, and fast. We are not investing sufficiently in maintenance of key assets to ensure their resilience in future, particularly in the face of climate change. Extreme weather also heightens the risk of flooding, with surface water flooding a key risk to many properties. And our transport systems in many places are not good enough.
Inevitably it’s a mixed picture, but that shouldn’t cloud the need for decisive action and the adoption of long term plans supported by adequate funding.
This is categorically not the time for complacency.
To underline this, we have decided that the second Assessment will focus on the three strategic themes of reaching net zero, climate resilience and the environment, and supporting levelling up.
Each pose urgent and wide ranging questions. Each draw broad political and public support for their end goal. Each, however, offer few quick wins or cheap fixes.
So, under the umbrella of the themes, we propose to tackle nine key challenges over the next two years, developing recommendations for the second Assessment, due in the second half of 2023. These challenges range from how we can accelerate work to decarbonise home heating, to how we can improve urban mobility and reduce congestion.
We will now embark on this work – informed by input and insight from industry, political leaders, representative bodies, other organisations across the country and the public – and formulate policy recommendations to put forward to government.
We hope this report prompts discussion, but also encourages optimism: a confidence that, working in a collaborative spirit, the private and public sectors can develop infrastructure solutions to meet the challenges of the second half of this century – so that every part of the UK can share in the rewards of a safer, cleaner, better connected society.

Next Section: Executive summary
Long term infrastructure policy can help address major future challenges such as reaching net zero, adapting to climate change, reducing environmental impacts, and levelling up across regions. The Commission will make recommendations to address these challenges in the second National Infrastructure Assessment, to be published in the second half of 2023. This document assesses the state of economic infrastructure today and identifies the future priorities for the second Assessment.
Executive summary
Long term infrastructure policy can help address major future challenges such as reaching net zero, adapting to climate change, reducing environmental impacts, and levelling up across regions. The Commission will make recommendations to address these challenges in the second National Infrastructure Assessment, to be published in the second half of 2023. This document assesses the state of economic infrastructure today and identifies the future priorities for the second Assessment.
The Commission has identified three strategic themes for the second Assessment:
- Reaching net zero: All sectors have more to do to reach net zero, particularly transport, where road and rail vehicles all need to become zero emission, energy, where government has committed to decarbonise electricity generation by 2035, and decarbonising heat, which will require major changes to the way people heat their homes.
- Climate resilience and the environment: While economic infrastructure has generally proved resilient to shocks and stresses over recent years, climate change will only increase pressures across all sectors, and infrastructure sectors have significant impacts – both positive and negative – on the environment.
- Supporting levelling up: There is significant variation in the quality of transport provision across England, which can affect economic outcomes, and people’s quality of life. Improving transport provision is therefore key to the government’s levelling up agenda.
All sectors must also take the opportunities offered by new digital technologies.
All of this will require significant levels of investment, which will ultimately be funded by consumers (via bills) or taxpayers. The Commission will carry out cross cutting analysis on all its recommendations for the second Assessment, including considering the overall affordability of required investment, the distribution of costs and savings across groups in society, and who should pay.
This document is the start of a conversation with the public and stakeholders about the country’s infrastructure needs and how to meet them, which will inform the development of the second Assessment. The Commission welcomes responses to the Call for Evidence questions set out in the document, and it will also hold a programme of events to gain new insights and evidence.
The second National Infrastructure Assessment
The Commission carries out a National Infrastructure Assessment once every five years. These set out the Commission’s assessment of long term needs in the transport, energy, water and wastewater, flood resilience, digital, and waste sectors, and recommendations to meet them, including the right policy, regulatory and funding mechanisms. The Assessments are guided by the Commission’s objectives to support sustainable growth across all regions of the UK, improve competitiveness and quality of life, and the Commission’s new objective to support climate resilience and the transition to net zero carbon emissions by 2050. The Assessments take a long term view, looking ahead over the next 10-30 years.
The Commission will publish the second Assessment in the second half of 2023. The second Assessment will build on the first Assessment and the Commission’s wider body of work, much of which is still relevant. It will focus on key challenges not covered in the first Assessment, areas where the Commission’s recommendations need to be updated, or where the Commission needs to address new issues.
The Baseline Report
Progress has been made in some areas since the first Assessment
The first Assessment was published in July 2018. Since then, it has shaped infrastructure policy across sectors. The government’s National Infrastructure Strategy, a formal response to the Assessment, aligned closely with the Commission’s recommendations, and there has been significant progress on many of the recommendations, including:
- access to gigabit capable broadband: the government has set out a clear vision to deliver gigabit capable broadband to at least 85 per cent of UK premises by 2025 – in late 2021 this was well underway, reaching over 50 per cent of premises
- a shift to renewable electricity: there has been a shift towards a highly renewable electricity system, with almost 40 per cent of electricity generated by renewable sources in 2019
- electric vehicles: government has banned the sale of new petrol and diesel cars and vans in the UK from 2030, following the Commission’s recommendation that charging infrastructure should be delivered to enable this shift
- flooding: the government will invest £5.6 billion over the next six years to reduce the risk of flooding, following Commission recommendations
- drought resilience: government and the water industry in England have taken on the Commission’s recommendations to increase water supply and reduce leakage
- the UK Infrastructure Bank: the independent infrastructure financing institution the Commission recommended be established following the UK’s loss of access to the European Investment Bank was launched in June 2021
- design principles: the government endorsed the Commission’s design principles and recommendation for board level design champions on major infrastructure projects.
Infrastructure has continued to perform well in some areas
The Commission’s performance assessment has identified several areas where infrastructure is performing well, including:
- access to mobile connectivity: 92 per cent of the UK landmass is covered by at least one mobile operator, with a funded plan to increase this to 95 per cent by 2026
- reliable energy supply: the energy sector delivers electricity and gas of reliable quality to consumers – loss of supply is rare, and interruptions to supply are reducing over time
- access to clean water: the water sector delivers water of reliable quality to homes and businesses across England, with low numbers of service interruptions, and customers are generally satisfied with the water and wastewater services provided.
Social research
In June 2021, the Commission carried out social research, with a range of respondents from across the UK, nationally representative by age, gender, region and ethnicity.
The research showed relatively high levels of confidence from respondents from across the UK that infrastructure will meet people’s needs over the next 30 years, with confidence increasing since the last Assessment. Only two sectors – flood resilience and waste – had lower than 70 per cent confidence, with the digital sector performing particularly strongly. This social research will shape the Commission’s approach to the second Assessment.

The research also showed that the public increasingly believe that infrastructure should lead the fight against climate change and a plan for infrastructure should consider the impact of infrastructure on the environment.
However, in other infrastructure areas, there is a lot more to be done
Nevertheless, there remain major significant challenges across sectors, particularly to reduce emissions. Key areas where infrastructure needs to improve performance:
- emissions from electricity and heat are still too high, as the electricity sector will need to reduce emissions to near zero by 2035, and little progress has been made so far on heat decarbonisation, although the technologies to do so already exist
- emissions from transport have not been declining, despite improvements in engine efficiency, and, although electric vehicle charge point numbers are increasing, the pace needs to pick up to enable a transition to electric vehicles in the 2020s and 2030s
- asset maintenance issues undermine performance in some sectors, including ageing and leaky water pipes and potholes in local roads
- more than five million properties are currently at risk of flooding in England, including more than three million at risk of surface water flooding
- serious pollution incidents from water and sewerage have plateaued at an unacceptably high level and 32 per cent of water bodies in England do not have good ecological status due to continuous discharges from sewage, and seven per cent due to stormwater overflows
- recycling rates have plateaued and emissions from waste have begun to rise again, while the total waste generated in England is also increasing
- urban transport connectivity is poor in many places, and the largest urban areas tend to have the worst connectivity, as congestion slows down journeys
- there are wide variations in interurban connectivity between similar places, but with no clear regional patterns or trends.
Progress is already being made in some of these areas, including reducing emissions from electricity, enabling the transition to electric vehicles, and reducing the risks of flooding. However, there is still further to go. More detail on the performance of each sector is set out in annexes A-F.
The overall cost to households of infrastructure services has remained relatively stable over the last 10 years. At the same time, there have been significant increases in investment in many areas. Average energy bills rose from the mid-2000s until the mid-2010s and then gradually declined.
However, gas prices have risen significantly in recent months, pushing up the price of both gas and electricity, as gas remains a significant input into electricity generation. Domestic consumers have been shielded from some of this volatility due to the regulated cap on energy prices introduced from 2017. But prices have risen and are expected to rise further. Businesses have also been affected, especially those that are energy intensive. This inevitably creates serious problems for some households and firms.
Current high prices appear to be mostly due to temporary factors, including the effects of the Covid-19 pandemic. Prices may fall again, but volatility in prices is inherent in a system dependent on fossil fuels. As set out below, this price volatility reinforces the strategic need to transition to a low carbon energy system as soon as practicable.
Infrastructure also faces new challenges
As well as improving current performance, infrastructure must be prepared for future challenges, including from a changing climate, and behaviour change following the Covid-19 pandemic. And it should also take the opportunities offered by new digital technologies.
Infrastructure sectors are beginning to tackle the challenge of reaching net zero, reducing the impact of infrastructure on the climate. But the climate will also have impacts on infrastructure. Sectors must prepare for the risks of a changing climate, including increased incidence of flooding and drought.
And alongside climate change, there is another environmental crisis that must be addressed. Global assessments show that nature is declining at rates unprecedented in human history, with accelerating rates of species extinction and severe disruption to ecosystem services. Infrastructure contributes to this decline but can also help prevent it.
Finally, the Covid-19 pandemic may lead to long term changes in where people live and work. This, in turn, could lead to new patterns of infrastructure demand, especially in the transport sector, where there may be a change in the established levels of demand for different modes. Car use has already returned to levels seen before the Covid-19 pandemic, but in the longer term the way people use roads and public transport could be very different.
Key challenges for the second Assessment
Bold action and stable plans will be needed to address the existing issues and prepare for the coming challenges. The Commission has identified the key areas that it will develop recommendations on in the second Assessment. The Commission has focussed on those that have a good fit with the Commission’s remit, are strategically important, and are an issue where the Commission can add value, considering the current policy landscape and the Commission’s existing work. The key challenges are set out thematically below, and in Chapters 1-3.
Figure 0.2: Key challenges for the second assessment
Digital technologies present opportunities for all sectors
Higher quality digital infrastructure will present opportunities across the economy, including the opportunity to make improvements in all other infrastructure sectors. The adoption of digital technologies has the potential to cut costs, enhance service quality, improve resilience, and enable better demand management, across a range of infrastructure services. Sensors can be deployed across infrastructure assets to monitor their condition, allowing for more timely and efficient maintenance interventions. Real time data on road use could facilitate better traffic management and alleviate congestion. However, the adoption of digital technologies in infrastructure is patchy.
Challenge 1: The digital transformation of infrastructure – the Commission will consider how the digital transformation of infrastructure could deliver higher quality, lower cost, infrastructure services.
Reaching net zero
To meet its legally binding climate targets, the UK must reduce its overall greenhouse gas emissions by 78 per cent compared to 1990 levels by 2035, and to net zero by 2050. In October 2021 the government published its Net Zero Strategy setting out how it will deliver against its commitment to reach net zero emissions by 2050.
Economic infrastructure sectors generate a major part of the UK’s current emissions – in 2019, direct emissions from the energy, transport, waste, and wastewater sectors accounted for over 66 per cent of all UK greenhouse gas emissions. Reducing emissions is important to the public: the Commission’s social research, carried out in June 2021, found that people cited fighting climate change by reducing greenhouse gases as the top priority for the UK’s infrastructure in 30 years’ time.

Reaching net zero will require high levels of investment, both to decarbonise existing infrastructure networks, and to build new ones, for example for carbon capture and storage, and hydrogen. This investment will ultimately need to be funded by either consumers (via bills) or taxpayers. The Commission will consider funding challenges in the second Assessment, including the overall affordability of required investment, the distribution of costs and savings across groups in society, and who should pay.
Decarbonising electricity generation
Electricity has made significant progress towards net zero, decarbonising faster than any other sector. In 2019, total emissions from electricity were around 60 MtCO2e, a reduction of 74 per cent since 1990. But the electricity system must now move away from fossil fuels – government has committed to electricity generation reaching nearly zero emissions by 2035 subject to being able to maintain security of supply. Over the same time, the electricity system will need to adapt to deliver on major increases in demand as other sectors decarbonise.
A net zero electricity system must also be secure and low cost. As the current energy price shock has shown, the volatility inherent in gas and oil prices – as internationally traded commodities – can have serious impacts on households and businesses. A low carbon electricity system, based more on long-lasting capital assets like wind farms and nuclear power plants, should reduce exposure to this kind of shock.
Challenge 2: Decarbonising electricity generation – the Commission will consider how a decarbonised, secure and flexible electricity system can be achieved by 2035 at low cost.
Decarbonising heat and improving energy efficiency
Decarbonising heat is complex, and progress has been slow. Total emissions from buildings in 2019 were around 90 MtCO2e, only a 17 per cent fall on 1990 levels. Most of these emissions arise from burning fossil fuels for heating. Providing zero carbon heat will likely require transitioning to a mix of electric heating and heat from hydrogen, alongside improving the energy efficiency of buildings with insulation to reduce the demand for energy for heat. The heat transition has so far proved difficult to implement, as it directly affects individuals and causes significant disruption in homes, buildings and at street level.
The government has recently published its strategy for decarbonising heat, via a gradual transition. It contains new funding commitments to support installation of low carbon heating systems in homes, with the goal that no new gas boilers will be sold by 2035. However, there are still major questions to be answered, including what level of insulation will be needed to efficiently operate heat pumps, whether hydrogen for heating will be available as a source of heat for all homes, what this means for the continuing use of the gas network, and how to deliver these major changes in people’s homes.
Challenge 3: Heat transition and energy efficiency – the Commission will identify a viable pathway for heat decarbonisation and set out recommendations for policies and funding to deliver net zero heat to all homes and businesses.
New networks to decarbonise hard to abate sectors
As well as transforming the existing infrastructure for electricity and heat, the UK needs new infrastructure networks to decarbonise, including:
- hydrogen networks, to help decarbonise hard to electrify sectors, such as heavy industry, shipping, aviation, heavy goods vehicles, parts of the rail network and heat
- carbon capture and storage networks, which will be needed to decarbonise parts of industry, hydrogen production, electricity generation (from sources such as waste incineration or biomass), and to enable engineered greenhouse gas removals.
Challenge 4: Networks for hydrogen and carbon capture and storage – the Commission will assess the hydrogen and carbon capture and storage required across the economy, and the policy and funding frameworks needed to deliver it over the next 10-30 years.
Climate resilience and the environment
Economic infrastructure has generally proved resilient to shocks and stresses over recent years, although good asset management will be important in future. Climate change will increase a variety of risks that affect economic infrastructure in the coming decades, with floods and drought a key risk.
Alongside climate change, there is another environmental crisis. Global assessments show that nature is declining at rates unprecedented in human history, with accelerating rates of species extinction and severe disruption to ecosystem services. Infrastructure contributes to this decline in natural capital and biodiversity but can also help prevent it. The Commission supports an ‘environmental net gain approach’ for all infrastructure projects (which includes, but is wider than, biodiversity net gain), ensuring that developers leave the environment in a measurably better state than they found it.
There are challenges in some sectors that affect the government’s objectives from the 25 Year Environment Plan, including minimising waste, and ensuring clean air and clean and plentiful water. The challenges under ‘reaching net zero’ will help to address the clean air objective, while the Commission’s previous recommendations supported the objective on clean and plentiful water. However, the net zero target means that the Commission will need to revisit its work on waste in the second Assessment, including considering how to further increase recycling. The government has also committed to move to a more circular economy, which could have wider implications for the sector.
Resilience must be embedded in asset management approaches
Good asset management requires managing infrastructure assets so that they can deliver services in a cost effective and timely way. This will be crucial to maintain resilience and performance as existing pressures increase or new ones emerge. There is already concern about the condition of assets in some sectors – the UK is still reliant on infrastructure built during the nineteenth century, including roads, railways, tunnels, water pipes and sewers. Some older components can be at greater risk of failure as they were not constructed to be resilient to extreme weather. There is also a lack of data on asset condition, and in some cases, deterioration is not noticed until a failure occurs. Furthermore, decision making frameworks can undervalue maintenance and disincentivise good asset management.
Challenge 5: Asset management and resilience – the Commission will consider how asset management can support resilience, barriers to investment, and the use of data and technology to improve the way assets are maintained.
Surface water management is a key resilience challenge
Droughts and floods will be a key risk for infrastructure as the climate changes. Government and industry are making progress on drought resilience and coastal and river flooding, following the Commission’s recommendations in the first Assessment. However, surface water flooding, which the Commission has not yet considered in detail, presents a risk to more than 3 million properties.
Multiple organisations are currently responsible for assets that affect surface water flooding, including local authorities, drainage boards, highways authorities and water companies. Relatedly, reducing sewer overflows, and the pollution they cause, will be a key challenge for the water and wastewater sector in the future. The government is making improvements in this area, but the scale of the challenge may require a more fundamental review of current arrangements. In the second Assessment, the Commission will carry out a dedicated study, as requested by government, on effective approaches for managing surface water in England. This will consider issues of planning, funding and governance arrangements, as well as the role of data and nature based solutions.
Challenge 6: Surface water management – the Commission will consider actions to maximise short term opportunities and improve long term planning, funding and governance arrangements for surface water management, while protecting water from pollution from drainage.
The Commission will deliver this as a separate study and report to government by November 2022, in advance of its other recommendations.
The waste sector can support the move to a circular economy
Waste infrastructure helps to protect the environment by enabling the safe collection, processing and disposal of municipal and industrial waste, preventing harmful waste products from entering the natural environment. The government has framed its waste objectives as part of the move to a more circular economy – one where products and materials are kept in productive use for longer, and the environmental impacts from extracting raw materials are reduced. In the second Assessment, the Commission will consider additional changes needed in the waste sector to enable the move to a more circular economy and to reduce the environmental impacts of waste. This will include looking at ways to increase recycling rates for municipal and construction waste and deliver the infrastructure needed to achieve net zero. It will also look at waste processing capacity and interdependencies with other economic infrastructure sectors including energy and water, and construction waste.
Challenge 7: Waste and the circular economy – the Commission will examine the role of the waste sector in enabling the move towards a more circular economy.
Supporting levelling up
The government has set itself the ambition of ‘levelling up’ outcomes across the UK, reducing disparities between different towns, cities and regions. These variations are caused by multiple interacting factors. Addressing these disparities is hard. Infrastructure can help address them, but it cannot do so singlehandedly.
Productivity potential varies as different parts of the country play different roles in the economy, and different places have different economic densities – for example, it is not realistic to have the same productivity in rural Cumbria as in central Manchester. While no two places are exactly the same, the Commission will look at broadly comparable places to assess economic potential.
While most infrastructure sectors can have some impact on outcomes, improvements in the transport sector can improve quality of life and help address constraints to growth and, with the right conditions, contribute to economic transformation in particular places – for example, major rail stations and other nationally significant infrastructure projects can offer significant potential for urban regeneration, and these opportunities should be maximised.
The Commission has made recommendations in the past to support levelling up, covering:
- Devolved powers and funding for cities and towns to develop locally led infrastructure strategies: Infrastructure strategies need to be developed and determined locally, by people who understand the needs and strengths of the area.
- The need for infrastructure strategies to form part of wider economic strategies: While infrastructure can improve productivity and make places more liveable, it is not the whole solution – factors like skills and education also have an important role to play and therefore need to be aligned to infrastructure investment.
- The need for local capacity to deliver these strategies: Government should make expert support and advice available to help those local authorities where capacity is an obstacle to developing and delivering their infrastructure strategies.
In the second Assessment, the Commission will take account of where places are not achieving their economic potential to identify where interventions are likely to deliver significant benefits – for example identifying where growth could be unlocked by increasing capacity in congested city centres – and consider how these interventions can improve both productivity and quality of life in the places concerned.
In the energy sector, the Commission will consider opportunities for major investments in new low carbon infrastructure to support levelling up by boosting growth in lower productivity places – the development of offshore wind energy has already created new opportunities for coastal towns close to large wind farms, such as Grimsby. The Commission will also analyse how each of its recommendations reduce regional differences and support improvements in national productivity.
Improved connectivity and reduced congestion can boost urban productivity
Before the Covid-19 pandemic, many major cities suffered from congestion and poor public transport connectivity, preventing goods, services and people from travelling in an efficient and sustainable way. Overcrowded or slow transport networks limited the ability of businesses and workers to locate in dense city centres, which has been a major barrier to urban productivity and growth.
The Covid-19 pandemic may lead to new travel patterns, changing the established levels of demand for different modes. Car use has already returned to levels seen before the Covid-19 pandemic, but in the longer term the way people use roads and public transport could be very different. Urban transport strategies need to be robust to different future scenarios.
The busiest cities with the most growth potential may need very large scale transport capacity projects, or network extensions allowing people in nearby towns to work some days in a central location. Demand management policies such as congestion charging may also be needed to maximise the benefits of transport for agglomeration and productivity.
Challenge 8: Urban mobility and congestion – the Commission will examine how the development of at scale mass transit systems can support productivity in cities and city regions and consider the role of congestion charging and other demand management measures.
A multi-modal transport strategy can support regional growth
Investment in interurban road and rail can support regional growth. Transport connectivity varies significantly between places, but there is not an obvious north-south or rural-urban divide in performance. Furthermore, technological innovation, decarbonisation and behaviour change all mean that patterns of transport demand, and ways to meet that demand, may be very different in future. It is difficult to determine the optimal balance of investment between different places and modes. A multi modal transport strategy could help the country plan more effectively for sustainable growth, quality of life outcomes and the shift to net zero, optimising the use of different accessible modes.
Challenge 9: Interurban transport across modes – the Commission will consider relative priorities and long term investment needs, including the role of new technologies, as part of a strategic multimodal transport plan.
Next steps
The Commission welcomes views on the themes and challenges it has identified for the second Assessment. Interested parties are encouraged to respond to the Call for Evidence questions set out in this document. The Commission will also hold a programme of events during the call for evidence period and in the run up to the second Assessment, to explore policy questions in detail with regional and sectoral stakeholders.
The Commission will also research the views and preferences of the public to shape its recommendations. The Assessment will be supported by expert panels of industry specialists, academics and regulators who will assess and challenge the Commission’s emerging thinking, and by its Design Group and Young Professionals Panel.
The Commission will take a range of approaches to manage uncertainty, including that created by the Covid-19 pandemic, by making recommendations which balance the risks of major investment, making complementary recommendations, and planning for future decisions. The Commission will use a range of scenarios, to be published in spring 2022.
Cross-cutting analysis
The Commission will carry out cross-cutting analysis to inform the policy options and assess the impact of recommendations in the Assessment across six categories:
- bills impact: the second Assessment will show the total costs of recommendations that will be raised through bills, including assessing the impact of the Commission’s recommendations on household bills overall, in line with its economic remit
- public spending impact: the Commission will set out the impact of its recommendations on gross public investment in economic infrastructure, in line with its fiscal remit
- distributional impacts: assessing whether recommendations will have disproportionate impacts on specific groups of people
- climate change impact: assessing the impacts of economic infrastructure and the Commission’s recommendations on greenhouse gas emissions
- environmental impact: assessing how the economic infrastructure and the Commission’s recommendations affect the UK’s natural capital and biodiversity
- regional impacts: assessing whether recommendations will have disproportionate impacts on regions.
The Commission will look at the appropriate policy, regulatory and funding mechanisms to meet the infrastructure needs covered by the recommendations in the second Assessment and will consider the most effective decision-making models for infrastructure, balancing national and local needs and priorities. Recommendations will also be guided by the Commission’s design principles for national infrastructure: climate, people, places, and value.
Next Section: 1. Introduction
Ahead of the second National Infrastructure Assessment, the Baseline Report sets out an evaluation of the performance of the six infrastructure sectors in the Commission’s remit, identifies nine key infrastructure challenges for the second Assessment and asks Call for Evidence questions on these topics. The key challenges are grouped under three strategic themes: reaching net zero, climate resilience and the environment, and supporting levelling up.
1. Introduction
Ahead of the second National Infrastructure Assessment, the Baseline Report sets out an evaluation of the performance of the six infrastructure sectors in the Commission’s remit, identifies nine key infrastructure challenges for the second Assessment and asks Call for Evidence questions on these topics. The key challenges are grouped under three strategic themes: reaching net zero, climate resilience and the environment, and supporting levelling up.

The first Assessment was published in July 2018.1 Since then, it has shaped infrastructure policy across the UK. The government’s National Infrastructure Strategy, a formal response to the Assessment, aligned closely with the Commission’s recommendations.2
The Baseline Report has three key functions:
- setting out an evaluation of the performance of the six economic infrastructure sectors
- identifying the nine key future infrastructure challenges for second Assessment, which will set out recommendations to address them
- inviting views on the set of challenges it has identified through call for evidence questions.
The Commission has identified the key challenges that it will consider in the second Assessment based on issues identified through the performance metrics, progress that is already being made, future trends and the public’s priorities as identified through social research. The Commission has also focussed on those that have a good fit with the Commission’s remit, are strategically important, and are an issue where the Commission can add value, considering the current policy landscape and the Commission’s existing work.
In October 2021, the Commission was given a new objective to support climate resilience and the transition to net zero carbon emissions by 2050. The Commission is confident that the key challenges identified are consistent with this new objective – the Commission has considered both climate resilience and net zero in its work to date,3 and both are strategic themes in this Baseline Report. Chapters 2-4 set out how each strategic theme aligns to all four of the Commission’s objectives.
Alongside a cross cutting digital challenge (see section 1.4), a further eight challenges have been identified, which are grouped under three strategic themes:
- reaching net zero
- climate resilience and the environment
- supporting levelling up.
The key challenges the Commission has identified are set out in figure 1.2.
Figure 1.2: Key challenges for the second assessment
The Commission will publish the second Assessment in the second half of 2023. The Commission – and the Assessments – take a long term view, making recommendations over the next 10-30 years and encouraging long term, stable infrastructure policy. Many recommendations from the first Assessment – or from the Commission’s studies, see box 1.1 – are therefore still relevant. In addition, government has made progress in implementing many of the Commission’s existing recommendations, where they were endorsed, or its own approach where they were not. The Commission will continue to monitor delivery but will not generally revisit these issues.
However, in some areas – such as the government’s commitments on the environment and climate, the effects of the Covid-19 pandemic, or technologies that can support infrastructure – the context has changed since the first Assessment. Therefore, while the first Assessment made recommendations across all sectors, the second will focus on the remaining key challenges, areas where the Commission’s recommendations need to be updated, or where the Commission needs to address new issues.
Following the first Assessment, the Commission carried out a comprehensive engagement process with its staff and external stakeholders to gather feedback. The conclusions of this were published in a paper in March 2019.4 The Commission has taken this feedback into account in this document, and in the plans for the second Assessment.
Box 1.1 Commission studies since the first Assessment
Box 1.1: Commission studies since the first Assessment
Since the first Assessment, the Commission has published studies as requested by government on:
Freight: The Commission found that through the adoption of new technologies and the recognition of freight’s needs in the planning system, it is possible to decarbonise road and rail freight by 2050 and manage its contribution to congestion. The government welcomed the core themes of the Commission’s report and will develop these themes through the Freight Council and the Future of Freight strategic Plan.
Regulation: The Commission’s regulation study set out how regulators, industry and government must adapt to face the coming challenges of achieving net zero, ensuring resilience, and increasing digitalisation. The study looked at how to keep critical services affordable, ensure competition, and attract the right levels of investment and innovation. The government has responded to the Commission’s recommendations to improve regulation and will set out further details later this year.
Resilience: The Commission’s study examined how to improve the resilience of the UK’s water, digital, transport and energy infrastructure, including the key strategic changes required to meet forthcoming challenges while maintaining levels of service for users. Government has accepted the potential role for more and better resilience standards and stress testing, and will set out further details in the National Resilience Strategy.
Rail Needs Assessment for the Midlands and the North: To inform the government’s Integrated Rail Plan, the Commission developed a menu of options for a programme of rail investments in the Midlands and the North, using three different illustrative budget options. The Commission recommended an adaptive approach, beginning with a core set of programmes. [Integrated Rail Plan outcome].
Engineered greenhouse gas removals: The study set out that engineered greenhouse gas removals will become a major new infrastructure sector for the UK over the coming decades. It recommended that government ensure the first engineered removals plants are up and running no later than 2030, delivering 5-10 MtCO2e of removals per year. The government’s Net Zero Strategy has since set an ambition to deploy at least 5 MtCO2e of engineered greenhouse gas removals by 2030, rising to around 23 MtCO2e by 2035, and a plan to consult in 2022 on business models to incentivise investment.
Towns: This study focused on towns and suburban centres, considering the potential for both economic and quality of life benefits from infrastructure intervention in different types of towns. The Commission awaits government’s response.
1.2 Work informing the second Assessment
The Baseline Report forms part of a wide body of work to inform the second Assessment. The Commission has published a number of supplementary papers since the first Assessment, aside from its studies (see above) and annual monitoring reports, and more are planned in the run-up to the second Assessment.
The Commission’s interpretation of its objectives
The Commission is in the process of publishing discussion papers on its interpretation of its objectives, including two discussion papers published to date covering the first two objectives:
- Supporting sustainable economic growth across regions: Growth across regions sets out the relationship between economic infrastructure and local growth and identifies three pathways for infrastructure investment to help achieve economic outcomes in regional areas: addressing constraints to growth, contributing to transformation, and universal provision.5
- Improve competitiveness: Improving competitiveness identifies three ways in which infrastructure can contribute to competitiveness: improving access to markets, improving access to mobile labour and capital, supporting and being a source of globally significant clusters and assets.6
The Commission is planning to publish a discussion paper on its quality of life objective in spring 2022. It has also published a literature review on the impacts of infrastructure on quality of life, which sets out a rapid evidence assessment of the impact of each of the Commission’s six infrastructure sectors on quality of life.7 The Commission has recently been given a new objective to support climate resilience and the transition to net zero carbon emissions by 2050 and will consider in due course whether to publish a discussion paper on this objective.
Drivers of infrastructure supply and demand
Ahead of the first Assessment, the Commission published documents on drivers of infrastructure supply and demand.8 The theoretical relationships between each of these drivers and infrastructure supply and demand remain largely unchanged since the first documents were published, however there are some updates:
- Environment and climate change – Chapter 3 sets out the Commission’s up to date understanding of the impact of climate change on the infrastructure sectors, and the impact of sectors on the environment.
- Economy – The UK is still recovering from the historic shock caused by the Covid-19 pandemic. The Commission will consider the implications of this as more data emerges, based on forecasts from the Office for Budget Responsibility.
- Population and demography – An ageing population, and the impact of the UK’s exit from the EU mean that population projections have changed since the original paper was published. The Office for National Statistics is expected to publish updated projections in December 2021. The Commission will consider the impact of these once latest projections are available.
- Technological change – The original paper included a horizon scan of new technologies that could impact infrastructures supply and demand.9 The Commission will publish an update to this in spring 2022.
- Behaviour change – Since the first Assessment, the Commission has published a fifth paper on a driver of infrastructure supply and demand: Behaviour change and infrastructure beyond Covid-19.10 The Commission will continue to monitor the impacts of behaviour change as data emerges.
The Commission will publish updates to the drivers and publish the set of scenarios it will use to develop the second Assessment in spring 2022.
1.3 Assessment of the infrastructure sectors
Progress has been made in some areas since the first Assessment
The first Assessment was published in July 2018. Since then, it has shaped infrastructure policy across sectors. The government’s National Infrastructure Strategy,11 a formal response to the Assessment, aligned closely with the Commission’s recommendations, and there has been significant progress on many of the recommendations, including:
- access to gigabit capable broadband: the government has set out a clear vision to deliver gigabit capable broadband to at least 85 per cent of UK premises by 2025 – in late 2021 this was well underway, reaching over 50 per cent of premises12
- a shift to renewable electricity: there has been a shift towards a highly renewable electricity system, with almost 40 per cent of electricity generated by renewable sources in 201913
- electric vehicles: government has banned the sale of new petrol and diesel cars and vans in the UK from 2030,14 following the Commission’s recommendation that charging infrastructure should be delivered to enable this shift
- flooding: the government will invest £5.6 billion over the next six years to reduce the risk of flooding, following Commission recommendations15
- drought resilience: government and the water industry in England have taken on the Commission’s recommendations to increase water supply and reduce leakage16
- the UK Infrastructure Bank: the independent infrastructure financing institution the Commission recommended be established following the UK’s loss of access to the European Investment Bank was launched in June 202117
- design principles: the government endorsed the Commission’s design principles and recommendation for board level design champions on major infrastructure projects.18
Infrastructure has continued to perform well in some areas
The Commission’s performance assessment has identified several areas where infrastructure is performing well, including:
- access to mobile connectivity: 92 per cent of the UK landmass is covered by at least one mobile operator, with a funded plan to increase this to 95 per cent by 202619
- reliable energy supply: the energy sector delivers electricity and gas of reliable quality to consumers – loss of supply is rare, and interruptions to supply are reducing over time20
- access to clean water: the water sector delivers water of reliable quality to homes and businesses across England, with low numbers of service interruptions, and customers are generally satisfied with the water and wastewater services provided.21
Social research
In June 2021, the Commission carried out social research, with a range of respondents from across the UK, nationally representative by age, gender, region and ethnicity.
The research showed relatively high levels of confidence from respondents from across the UK that infrastructure will meet people’s needs over the next 30 years, with confidence increasing since the first Assessment. Only two sectors – flood resilience and waste – had lower than 70 per cent confidence, with the digital sector performing particularly strongly. This social research will shape the Commission’s approach to the second Assessment.

Source: PwC (2021), NIA2 Social Research: Final report
The research also showed that the public increasingly believe that infrastructure should lead the fight against climate change and a plan for infrastructure should consider the impact of infrastructure on the environment.22
However, in other infrastructure areas, there is a lot more to be done
Nevertheless, there remain major significant challenges across sectors, particularly to reduce emissions. Key areas where infrastructure needs to improve performance:
- emissions from electricity and heat are still too high, as the electricity sector will need to reduce emissions to near zero by 2035,23 and little progress has been made so far on heat decarbonisation, although the technologies to do so already exist
- emissions from transport have not been declining, despite improvements in engine efficiency,24 and, although electric vehicle charge point numbers are increasing,25 the pace needs to pick up to enable a transition to electric vehicles in 2020s and 2030s26
- asset maintenance issues undermine performance in some sectors, including ageing and leaky water pipes and potholes in local roads27
- more than five million properties are currently at risk of flooding in England,28 including more than three million at risk of surface water flooding29
- serious pollution incidents from water and sewerage have plateaued at an unacceptably high level,30 and 32 per cent of water bodies in England do not have good ecological status due to continuous discharges from sewage, and seven per cent due to stormwater overflows31
- recycling rates have plateaued and emissions from waste have begun to rise again, while the total waste generated in England is also increasing32
- urban transport connectivity is poor in many places, and the largest urban areas tend to have the worst connectivity, as congestion slows down journeys33
- there are wide variations in interurban connectivity between similar places, but with no clear regional patterns or trends.34
Progress is already being made in some of these areas, including reducing emissions from electricity, enabling the transition to electric vehicles, and reducing the risks of flooding. However, there is still further to go. More detail on the performance of each sector is set out in annexes A-F.
The overall cost to households of infrastructure services has remained relatively stable over the last 10 years.35 At the same time, there have been significant increases in investment in many areas. Average energy bills rose from the mid-2000s until the mid-2010s and then gradually declined.
However, gas prices have risen significantly in recent months, pushing up the price of both gas and electricity, as gas remains a significant input into electricity generation. Domestic consumers have been shielded from some of this volatility due to the regulated cap on energy prices introduced from 2017. But prices have risen and are expected to rise further. Businesses have also been affected, especially those that are energy intensive. This inevitably creates serious problems for some households and firms.
Current high prices appear to be mostly due to temporary factors, including the effects of the Covid-19 pandemic. Prices may fall again, but volatility in prices is inherent in a system dependent on fossil fuels. As set out below, this price volatility reinforces the strategic need to transition to a low carbon energy system as soon as practicable.

Infrastructure also faces new challenges
As well as improving current performance, infrastructure must be prepared for future challenges, including from a changing climate, and behaviour change following the Covid-19 pandemic. And it should also take the opportunities offered by new digital technologies.
Infrastructure sectors are beginning to tackle the challenge of reaching net zero, reducing the impact of infrastructure on the climate. But the climate will also have impacts on infrastructure. Sectors must prepare for the risks of a changing climate, including increased incidence of flooding and drought.
And alongside climate change, there is another environmental crisis that must be addressed. Global assessments show that nature is declining at rates unprecedented in human history, with accelerating rates of species extinction and severe disruption to ecosystem services.36 Infrastructure contributes to this decline but can also help prevent it.
Finally, the Covid-19 pandemic may lead to long term changes in where people live and work. This, in turn, could lead to new patterns of infrastructure demand, especially in the transport sector, where there may be a change in the established levels of demand for different modes. Car use has already returned to levels seen before the pandemic, but in the longer term the way people use roads and public transport could be very different.37
Call for evidence questions
This document contains call for evidence questions on each of the nine challenges. These are mostly set out where the challenge is identified. However, there are several cross cutting call for evidence questions that are relevant across all nine challenges, set out below. A summary of call for evidence questions and information on how to respond is set out in chapter 5.
Question 1: Do the nine challenges identified by the Commission cover the most pressing issues that economic infrastructure will face over the next 30 years? If not, what other challenges should the Commission consider?
Question 2: What changes to funding policy help address the Commission’s nine challenges and what evidence is there to support this? Your response can cover any number of the Commission’s challenges.
Question 3: How can better design, in line with the Design Principles for National Infrastructure, help solve any of the Commission’s nine challenges for the next Assessment and what evidence is there to support this? Your response can cover any number of the Commission’s challenges.
Question 4: What interactions exist between addressing the Commission’s nine challenges for the next Assessment and the government’s target to halt biodiversity loss by 2030 and implement biodiversity net gain? Your response can cover any number of the Commission’s challenges.
Question 5: What are the main opportunities in terms of governance, policy, regulation and market mechanisms that may help solve any of the Commission’s nine challenges for the Next Assessment? What are the main barriers? Your response can cover any number of the Commission’s challenges.
1.4 Digital technologies present opportunities for all sectors
The Commission made recommendations on the availability and quality of digital infrastructure in the first Assessment, and the government is making good progress delivering on this, as set out above. The Commission will continue to monitor government progress in these areas through the Annual Monitoring Report but does not plan to undertake new work on network roll-out as part of the second Assessment. Instead, the Commission will turn its attention to how the widespread availability of fixed and mobile networks and services can be used in other infrastructure sectors to deliver better services at lower cost.
Higher quality digital infrastructure will present opportunities across the economy, including the opportunity to make improvements in all other infrastructure sectors. Adoption of digital technologies has the potential to cut costs, enhance service quality, improve resilience, and enable better demand management, across a range of infrastructure services. Sensors can be deployed across infrastructure assets to monitor their condition, allowing for more timely and efficient maintenance interventions. Real time data on road use could facilitate better traffic management and alleviate congestion. However, the adoption of digital technologies across infrastructure sectors is patchy. The second Assessment will consider barriers that are preventing the adoption of new digital technologies in infrastructure, and what policy and regulatory interventions may be needed.
Challenge 1: The digital transformation of infrastructure – the Commission will consider how the digital transformation of infrastructure could deliver higher quality, lower cost, infrastructure services.
Question 6: In which of the Commission’s sectors (outside of digital) can digital services and technologies enabled by fixed and wireless communications networks deliver the biggest benefits and how much would this cost?
Question 7: What barriers exist that are preventing the widescale adoption and application of new digital services and technologies to deliver better infrastructure services? And how might they be addressed? Your response can cover any number of the Commission’s sectors outside digital (energy, water, flood resilience, waste, transport).
Next Section: 2. Reaching net zero
The effects of climate change, which are already evident in the UK and worldwide, can only be mitigated by cutting greenhouse gas emissions, fast. In 2019, two thirds of all UK greenhouse gas emissions arose from transport, energy, waste and wastewater infrastructure. While progress has been made in these sectors, they all need to decarbonise further. And the move to net zero will also require new infrastructure networks for hydrogen and carbon capture and storage.
2. Reaching net zero
The effects of climate change, which are already evident in the UK and worldwide, can only be mitigated by cutting greenhouse gas emissions, fast. In 2019, two thirds of all UK greenhouse gas emissions arose from transport, energy, waste and wastewater infrastructure. While progress has been made in these sectors, they all need to decarbonise further. And the move to net zero will also require new infrastructure networks for hydrogen and carbon capture and storage.
In the second Assessment, the Commission will focus on the following key challenges:
- decarbonising electricity generation by 2035
- the heat transition and energy efficiency
- new networks for hydrogen and carbon capture and storage.
While the decarbonisation of surface transport is discussed in this chapter, transport will be covered as part of the challenges outlined in chapter 4. Similarly, waste will be considered in the circular economy challenge set out in Chapter 3. The water, floods and digital sectors have much lower emissions and so will not be considered as priority challenges for decarbonisation in the second Assessment, although the Commission will assess the emissions impact of all the recommendations it makes.
2.1 Infrastructure and net zero
In 2019, UK greenhouse gas emissions stood at around 500 MtCO2e, a reduction of 40 per cent since 1990.38 The UK has legally binding targets to reduce greenhouse gas emissions by 78 per cent by 2035 relative to 1990 levels,39 and to net zero by 2050.40 In October 2021, the government published its Net Zero Strategy – a summary of the actions it is taking, and plans to take, to deliver against its commitment to reach net zero emissions by 2050.41
Reductions in emissions have so far been concentrated largely in the electricity sector, with only limited progress in most other infrastructure sectors (figure 2.1).
Figure 2.1: Total UK emissions have reduced since 1990, especially in electricity generation
Annual greenhouse gas emissions by infrastructure sector, 1990 to 2019
Source: Commission calculations using Department for Business, Energy & Industrial Strategy (2021), Final UK greenhouse gas emissions national statistics: 1990 to 2019
In 2019, two thirds of all UK greenhouse gas emissions arose from transport, energy, waste and wastewater infrastructure:
- transport (including surface transport, aviation and shipping) emitted around 165 MtCO2e (33 per cent of all UK emissions)
- electricity generation emitted around 50 MtCO2e (11 per cent)
- heat for residential, public sector, and commercial buildings emitted around 90 MtCO2e (17 per cent)
- waste emitted just over 20 MtCO2e (4 per cent)42
- wastewater emitted around 3 MtCO2e (less than 1 per cent).
In the transport sector, the route to net zero is clear for cars and vans, but more complicated for HGVs, rail, planes and ships. And while cars and vans can be decarbonised by the switch to electric vehicles, this needs to accelerate to meet the sixth Carbon Budget target – government must ensure public charge points are available to encourage take up.
In the energy sector, there is a clear route to decarbonise the electricity system. But it needs to happen fast – the electricity system must be near zero emissions by 2035. In heat, the challenge is different – the technologies to decarbonise heat exist, but how to deliver the necessary changes in homes and businesses is not clear.
To decarbonise the waste sector, emissions from landfill must be reduced. More detail on how the Commission will consider the waste sector in the second Assessment is set out in chapter 3. The Commission will also look at the emissions from energy from waste plants as part of the wider electricity system.
The Commission is not planning to consider process emissions from wastewater treatment as a priority in the second Assessment, as these represent a very small proportion of overall emissions.
The Commission’s other infrastructure sectors – the water, flood resilience and digital sectors – do not directly emit greenhouse gases in the way that power stations or cars do. Their reliance on energy and transport infrastructure does indirectly raise emissions, but, as those sectors decarbonise, the emissions from the water, flood resilience and digital sectors will also fall. The water, flood resilience and digital sectors are therefore not considered in this chapter.
The move to net zero will also require new infrastructure networks, including for hydrogen and carbon capture and storage. Government has set out strategies for both, however, there are still many questions to be resolved. It still needs to be determined how quickly these networks can be delivered, at what scale, and how plans can be coordinated.
Achieving net zero – a 100 per cent reduction in net (rather than gross) greenhouse gas emissions from 1990 levels – means that some sectors are still expected to emit a small amount of greenhouse gases in 2050. These will have to be offset by greenhouse gas removals, which the Commission considered in its 2021 report Engineered greenhouse gas removals.43
All infrastructure sectors have emissions ‘embedded’ in their construction process, and in their use of materials. Hydrogen and carbon capture and storage are two of the solutions to decarbonising the production of construction materials. The infrastructure needed to allow for this will be considered by the Commission.
All infrastructure sectors need to decarbonise further, fast, to meet the government’s emissions targets for 2035 and 2050. While the legally binding net zero and sixth Carbon Budget targets only refer to total UK emissions across all sectors, the government has set out illustrative sectoral ranges for emissions reductions in its Net Zero Strategy.44 These ranges are similar to the illustrative roadmaps produced by the Climate Change Committee to meet both the sixth Carbon Budget and net zero target. The Commission uses these illustrative roadmaps as guidance for the expected decarbonisation path in its infrastructure sectors. The Climate Change Committee’s ‘balanced pathway’ scenario for each sector is shown in figure 2.2.
Many areas of economic infrastructure are devolved, see chapter 1. The Commission’s role is to advise the UK Government. This chapter therefore focusses on UK Government climate targets and areas of competence.

Emissions reduction roadmaps for economic infrastructure in the Climate Change Committee’s ‘balanced pathway’ scenario

Box 2.1: Reaching net zero is a key theme for the Commission
Reaching net zero supports all four of the Commission’s objectives:
- Support sustainable economic growth across all regions of the UK: Reducing greenhouse gas emissions is vital for economic growth. The scale of the productivity impacts of heatwaves and other extreme weather is likely to be in the order of billions of pounds per year.45 The benefits from mitigating climate change will be felt across all regions. There are likely to be some economic benefits in areas where new low carbon industries are located, through jobs created in the construction and operation of these industries and through associated services. However, the transition away from oil and gas may have the opposite effect in places where these industries are centred.
- Improve competitiveness: Many of the UK’s existing competitive advantages are in high carbon industries. Net zero means that some of these industries face uncertain futures. But the UK can and should transfer its advantages – which lie across a broad range of professional, financial, and engineering and design services – to emerging low carbon industries, such as carbon capture and storage and electric vehicle technology.46 Getting ahead of this challenge now will maximise the UK’s future competitiveness as the global economy shifts towards net zero.
- Improve quality of life: Reducing greenhouse gas emissions is expected to help mitigate the impacts of climate change, which have significant impacts on quality of life in the UK and globally.47 The largest impacts are likely to be on health and availability (and therefore affordability) of food. It will also impact on quality of life through affecting infrastructure and access to infrastructure services, for example from flooding or overheated train tracks.48
- Support climate resilience and the transition to net zero carbon emissions by 2050: Reaching emissions targets in economic infrastructure will reduce emissions not only in those sectors, but also in the sectors that depend on them. Reducing greenhouse gas emissions will also help mitigate climate change, supporting climate resilience.
The Commission’s social research found that people increasingly rank reducing emissions as a priority for infrastructure. Respondents cited fighting climate change by reducing greenhouse gases as the top priority for the UK’s infrastructure in 30 years’ time.49
2.2 Transport
In 2019, greenhouse gas emissions from the transport sector stood at around 165 MtCO2e, or 33 per cent of total UK emissions that year. Emissions from transport broadly fall into two categories:
- surface transport, which emitted around 115 MtCO2e in 2019
- aviation and shipping, both domestic and international, which emitted around 50 MtCO2e in 2019.
Figure 2.3: Surface transport makes up two thirds of transport emissions
Annual greenhouse gas emissions by transport mode, 2019
Source: Commission calculations using Department for Business, Energy & Industrial Strategy (2021), Final UK greenhouse gas emissions national statistics: 1990 to 2019
Surface transport
In 2019, emissions from surface transport made up around two thirds of all transport emissions in the UK.50 These emissions have persisted at similar levels since 1990. Surface transport emissions arise from:
- cars, taxis, light vans, motorcycles, and mopeds, which produce just under 8o per cent of emissions from surface transport
- HGVs, buses and coaches, which emitted around 25 MtCO2e in 2019, around 20 per cent of surface transport emissions, with the majority coming from HGVs
- railways, which emitted less than 2 MtCO2e in 2019 – this is close to a 15 per cent reduction on 1990 emissions, despite a 115 per cent rise in passenger journeys.51
The Climate Change Committee’s balanced pathway scenario assumes emissions from surface transport will fall to 32 MtCO2e by 2035 and to 1 MtCO2e by 2050.52
Cars, taxis, light vans, motorcycles, and mopeds
The move to electric cars and vans will eliminate the majority of emissions from surface transport. In the first Assessment, the Commission recommended the roll out of charging infrastructure sufficient to enable 100 per cent electric new car and van sales by 2030.53 Government has since committed to ending the sale of new petrol and diesel cars and vans in the UK by 2030, and to working closely with Ofgem, and industry to ensure there is the charging infrastructure in place to support this.54
However, plans to deliver an electric vehicle charging network must accelerate if electric vehicle take up is to happen at the pace needed to meet the sixth Carbon Budget, which will require a significant shift to electric vehicles over the 2020s. Without available chargers, drivers will not have the confidence to make the switch. As of July 2021, there were around 24,300 public charging points.55 It is estimated that between 280,000 and 480,000 public charging points would be needed to support 100 per cent electric new car and van sales in 2030.56
In the National Infrastructure Strategy, government committed to publish an electric vehicle charging infrastructure strategy by November 2021.57 This is urgently required to help support the delivery of charging infrastructure that will encourage drivers to make the required switch to electric vehicles. It will also help both the market and local authorities plan the delivery of additional charging points. Ofgem has recently published its priorities for enabling the transition to electric vehicles, setting out plans to ensure that the networks are prepared for increased adoption, and that network connections are timely and cost effective. It also outlines how it will support off peak ‘smart charging’ using market incentives and support the sale of battery stored electricity back to the grid.58
HGVs, buses and coaches
Decarbonising heavy road vehicles presents a further challenge. The options being considered to decarbonise HGVs are hydrogen and electrification, either of which would require a change in existing fuelling infrastructure. The Commission has recommended that new diesel HGV sales should end by 2040.59 This year, the government committed to phase out the sale of new non zero emissions HGV’s by 2040.60 The government’s forthcoming ‘Future of Freight Plan’ must address the need for a comprehensive assessment of the infrastructure needed to enable freight HGV decarbonisation, including working with Ofgem and distribution network operators to plan any necessary infrastructure upgrades.
In its Transport Decarbonisation Plan, government committed to measures to boost zero emission bus fleets. Currently only two per cent of English buses are run on lower carbon fuel, such as electricity or hydrogen.61
Railways
In the rail industry, many of the intercity mainlines and almost all London commuter routes have already been electrified.62 Further electrification of the rail network will reduce emissions. The Commission has called for a rolling programme of electrification to be established but has noted that detailed work will be needed to establish which routes are the priority for early electrification.63 The Commission has also recommended that government publish a detailed strategy for achieving rail freight decarbonisation by 2050.64 The high costs associated with installing overhead line electrification pose a challenge for decarbonising all rail routes;65 for some, battery or hydrogen trains may offer an alternative means of decarbonising.66 Government has committed to encourage the development of battery and hydrogen trains in the Transport Decarbonisation Plan.
Chapter 4 sets out the Commission’s plans to look at improving urban and interurban transport. As the Commission develops transport recommendations for the second Assessment, it will ensure these recommendations are consistent with the government’s decarbonisation targets.
Aviation and shipping
In 2019, emissions from aviation and shipping stood at around 50 MtCO2e. Emissions from shipping have declined since 1990. But international aviation emissions were on a strong upwards trend prior to the Covid-19 pandemic, reaching close to 40 MtCO2e in 2019.
Figure 2.4: UK emissions from aviation and shipping in 2019
Source67
Aviation | Shipping | |
---|---|---|
Domestic | 1 MtCO2e | 6 MtCO2e |
International | 37 MtCO2e | 8 MtCO2e |
Aviation and shipping are particularly difficult to decarbonise. The technologies to do so do not yet exist or are not yet mature enough to be used at scale.68 The Climate Change Committee’s balanced pathway scenario assumes that emissions from aviation and shipping will remain at 24 MtCO2e even in 2050.69 Greenhouse gas removals will therefore be necessary to offset the remaining emissions in this sector. The international aviation sector has committed to offset growth in emissions from 2019 levels through the UN Aviation Agency’s Carbon Offsetting and Reduction Scheme for International Aviation.70
The Commission has recommended that engineered greenhouse gas removals are developed in the UK to address emissions from this hard to abate sector.71 The government’s Net Zero Strategy has since set an ambition to deploy at least 5 MtCO2e of engineered greenhouse gas removals by 2030, rising to around 23 MtCO2e by 2035, and a plan to consult in 2022 on business models to incentivise investment. The Commission will continue to promote its recommendations and monitor government’s progress in establishing an engineered removals sector in the UK. The Commission does not intend to take forward any further work during the second Assessment on the infrastructure required to decarbonise aviation and shipping.
2.3 Energy
In 2019, emissions from the energy sector stood at around 140 MtCO2e, equivalent to 28 per cent of UK emissions for that year. Despite dramatic reductions in emissions from electricity generation, energy infrastructure remains the largest source of emissions after transport. Emissions from energy arise from:
- electricity generation, which emitted around 50 MtCO2e in 2019, a fall of 74 per cent since 199072
- heat for residential, public sector, and commercial buildings, which emitted around 90 MtCO2e in 2019, 17 per cent of total emissions.
Average energy bills rose from the mid 2000s until the mid 2010s, before gradually declining. However, gas prices have risen significantly in recent months, which has pushed up the price of both gas and electricity as gas remains a significant input into electricity generation. Domestic consumers have been shielded from some of this volatility due to the regulated cap on energy prices introduced from 2017. But prices have risen and are expected to rise further. Businesses have also been affected, especially those that are energy intensive. This inevitably creates serious problems for some households and firms.
Oil and gas are internationally traded commodities with volatile prices determined by factors over which the UK has little control. Current high prices appear to be mostly due to temporary factors, including the effects of the Covid-19 pandemic.73 Prices may fall again, but volatility in prices is inherent in a system dependent on fossil fuels. Transitioning to a low carbon energy system based on long lasting capital assets, such as wind farms and nuclear power stations, with less dependence on fuel should reduce exposure to price spikes like those currently being experienced.
Decarbonising energy will require high levels of investment, both to decarbonise existing infrastructure networks, and to build new ones, for example for carbon capture and storage, and hydrogen. This investment will ultimately need to be funded by either consumers (via bills) or taxpayers. The Commission will consider funding challenges in the second Assessment, including the overall affordability of required investment, the distribution of costs and savings across groups in society, and who should pay.
Electricity generation
Electricity generation has made significant progress in reducing emissions, decarbonising faster than any other sector. The share of electricity generated from renewable sources has grown from less than 10 per cent in 2010 to almost 40 per cent in 2019.74
The pathway to decarbonise electricity generation is clear: electricity generation needs to primarily come from low carbon energy sources (like wind, solar and nuclear), complemented by storage, interconnection with other countries, demand management and novel flexible low carbon generation such as hydrogen, or gas or biomass with carbon capture and storage. The transmission and distribution networks will need to be ready to support these new sources of generation and manage increased demand (such as from electric vehicles) as other sectors decarbonise.
In the first Assessment, the Commission recommended that government aim to deliver 50 per cent renewable generation by 2030.75 The Commission later increased that recommendation to 65 per cent by 2030, in light of faster than expected cost reductions in renewable technologies.76 Since the Commission reached this position the government has committed to the sixth Carbon Budget and to decarbonising the electricity system by 2035 (subject to being able to maintain security of supply).77 Reaching near zero emissions by 2035 will require an acceleration in the current pace of decarbonisation. While reliance on coal and oil has dropped significantly, gas remains the largest single source of electricity generation, holding around a 40 per cent share of generation in 2019.78
Delivering this will require significant new capacity to be deployed over the next decade. The government has committed to achieving 40 GW of offshore wind generation by 2030 and is reopening Contracts for Difference auctions, held approximately every two years, to onshore wind and solar.79 These actions are in line with the Commission’s recommendations. Government and industry must now focus on delivery.
While the pathway to decarbonisation is clear and progress is being made, the energy sector still faces a significant challenge. A low cost, net zero electricity system, capable of meeting increased demand must be delivered without jeopardising security of supply. Renewable electricity generation from solar or wind cannot be turned on when needed like a gas power plant can, so flexibility, including through electricity storage, will be vital for a highly renewable electricity system. There is some evidence that the electricity storage market is maturing. Battery storage capacity exceeded 1 GW for the first time in 2021, and the pipeline of battery storage projects has expanded rapidly in the last three years.80 The government and Ofgem recently updated their Smart Systems and Flexibility Plan and issued a call for evidence on facilitating the deployment of large scale and long duration electricity storage.81
Challenge 2: Decarbonising electricity generation – the Commission will consider how a decarbonised, secure and flexible electricity system can be achieved by 2035 at low cost.
Heat
Decarbonising heat is complex, and limited progress has been made. While the technologies to decarbonise heat exist, delivering the transition to zero carbon heat presents a significant challenge to policymakers, as it will directly affect individuals and will cause significant disruption in homes, buildings and at street level.
Most of the emissions from heat arise from burning fossil fuels for heating and hot water. Total emissions from buildings in 2019 were around 90 MtCO2e, only a 17 per cent fall on 1990 levels. This includes a 15 per cent reduction in residential combustion emissions, supported by improved efficiency of heating systems and government schemes to encourage the installation of energy efficiency measures in homes.82 Reductions began to tail off in 2014 as those schemes ended or were reduced in scope, and emissions have plateaued since then.83
Over 75 per cent of the energy needed for heating space and water in homes is provided by natural gas, with oil, electricity and bioenergy providing under 10 per cent each.84 This reliance on fossil fuels will need to end to reach net zero – the Climate Change Committee’s balanced pathway scenario sees emissions from heating falling to 47 MtCO2e by 2035 and to 1 MtCO2e by 2050.85
Providing zero carbon heat will require both:
- Improving energy efficiency of buildings: This will reduce the amount of heat that is lost and therefore reduce the demand for energy for heat. The UK has some of the oldest and least energy efficient homes in Europe.86 Improving energy efficiency will require millions of existing homes to be better insulated, for example by double glazing windows or increasing insulation in walls and roofs and new homes to be built to high levels of efficiency.
- Transitioning to a mix of electric heating and heat from hydrogen: This will mean replacing fossil fuel heating systems, mainly natural gas boilers, with lower carbon alternatives that use electricity, like heat pumps or heat networks, or hydrogen, or hybrid systems. The appropriate balance between these sources of heat is not yet clear.
In the first Assessment, the Commission recognised that difficult decisions would need to be made about how and when the UK’s reliance on natural gas for heating will come to an end. It therefore recommended a series of near term actions to build the evidence base on heat decarbonisation and improve energy efficiency, including:
- setting a target rate of installing 21,000 energy efficiency measures per week in England by 2020, and allocating funding to enable this
- establishing an up to date evidence base on the performance of heat pumps within the building stock and getting a better understanding of the scope for future cost reductions
- establishing the safety case for hydrogen and trialling it, first at community scale by 2021 and then a larger trial, of at least 10,000 homes, by 2023.87
Government accepted the Commission’s recommendations on gathering evidence on heat pumps and the use of hydrogen for heating. It did not support setting a target for the number of energy efficiency measures. Progress is lagging behind the Commission’s recommended timetable.88
The energy efficiency of homes in England has been gradually improving.89 But government policy to date to spur action has been stop start. Energy efficiency installations are therefore falling short of what is needed. In 2019, the number of energy efficiency installations installed through government schemes averaged 4,200 per week, far below levels in the early 2010s.90 Heat pump installations remain low at 36,000 a year,91 far below the government ambition to get installations to 600,000 a year by 2028.92
Box 2.2: Heat decarbonisation in Europe
The UK is not alone in facing the challenge of heat decarbonisation. But it is unusual in the degree to which it currently depends on gas boilers for heating. The UK has one of the highest levels of on gas grid heating in the OECD.93
Most other European countries already generate much of their energy for heating through sources other than natural gas, such as electricity or biofuels and make greater use of district heating systems to transport heat. It is estimated that 85 per cent of heating in Norway is provided by electricity, mainly generated through hydroelectricity, and 60 per cent of heating in Sweden is from district heating with electricity meeting most of the remaining demand.94 Heat pumps are installed in approximately a fifth of Swedish homes.95 These countries have benefitted from converting district heating systems originally powered by coal and oil to less carbon intensive sources.96
The UK’s closest comparator in terms of heating systems is the Netherlands, where in 2016 nearly 95 per cent of households were connected to the gas grid.97 The Netherlands has banned new connections to its gas grid.98 It has also committed to scaling up production of low carbon hydrogen by 2030 and 46 local authorities are piloting alternative heating technologies, with many opting to install heat pumps.99
The UK Government has recently published its strategy for decarbonising heat.100 The Scottish and Welsh Governments are also focused on this issue.101 The UK Government’s strategy sets out plans to cut emissions via a gradual transition which will start by incentivising consumers, through grant funding to install heat pumps, and working with industry to drive down their cost and encourage uptake. It also outlines measures to promote improved efficiency to business and public sector buildings. The stated ambition is that by 2035 no new gas boilers will be sold.
The lack of progress to date in decarbonising heat, and the legislated sixth Carbon Budget mean understanding and resolving the challenges that the UK will face in decarbonising its homes and businesses is now urgent. There are still major questions to be answered, as acknowledged in the Heat and Buildings Strategy.102 These questions include: what level of insulation will be needed in different homes to efficiently operate heat pumps; whether hydrogen for heating will be available as a source of heat for all homes and what this means for the continuing use of the gas network; and how to deliver these major changes in people’s homes.
The Commission does not yet have the answers to these questions. But it will continue to work with government to build a stronger evidence base, so that these important decisions can be made in time to meet carbon targets. The government has committed to making a decision on the role of hydrogen for heating by 2026.103 If this does not happen, the risk of not achieving net zero is very real.
In tackling these questions, the Commission will consider how the heat transition will impact household bills. Using a heat pump currently costs more than a natural gas boiler as both the upfront installation cost and running cost are higher. And while hydrogen boilers are expected to have a similar cost to natural gas boilers, the running costs are currently uncertain and will depend on the cost of producing hydrogen. Making the change to zero carbon heat in a well planned way, with appropriately targeted policy, can ease the burden on the most vulnerable.
Challenge 3: Heat transition and energy efficiency – the Commission will identify a viable pathway for heat decarbonisation and set out recommendations for policies and funding to deliver net zero heat to all homes and businesses.
2.4 Waste
In 2019, emissions from the waste sector stood at just over 20 MtCO2e, four per cent of total UK emissions. Emissions from waste arise from:
- landfill waste, which represented the majority of emissions in 2019
- incineration, composting, anaerobic digestion and mechanical biological treatment, which make up around 2 MtCO2e
- energy from waste plants, which represent around 5 MtCO2104
These domestic figures do not account for emissions from exporting waste.
Emissions from waste fell significantly from 1990 to 2014. Most of the reduction in emissions from waste to date has been due to falling methane emissions from landfill following the landfill tax – the UK achieved an 84 per cent reduction in biodegradable waste sent to landfill between 1990 and 2015 (see Annex C).105 However, landfill emission reductions have stagnated and energy from waste emissions have grown, which has caused a 10 percent increase in emissions since 2015.106 Reducing the volume of waste that is disposed of through landfill or incineration without recovery – or reducing emissions from treatments such as incineration with energy recovery – is therefore critical to reducing overall emissions in the waste sector.
The net zero target means that the Commission will need to revisit its work on waste in the second Assessment. More detail on how the Commission will consider the waste sector in the second Assessment is set out in chapter 3. The Commission will consider emissions from energy from waste plants under challenge 2 (see section 2.3).
2.5 Wastewater
The wastewater sector emitted around 3 MtCO2e in 2019, less than one per cent of total UK emissions. These emissions have been broadly stable since 1990. These emissions arise from wastewater handling.
The Commission is not planning to consider process emissions from water and wastewater treatment as a priority in the second Assessment due to the low level of overall emissions and the industry’s ambition.107
More detail on the performance of the water and wastewater sector is set out in Annex D.
2.6 New infrastructure networks to support net zero
Tackling emissions from some sectors – largely from harder to abate sectors such as industry, aviation, agriculture, and shipping – will require new infrastructure networks. These will include:
- hydrogen networks, to help decarbonise hard to electrify sectors, such as heavy industry, shipping, aviation, heavy goods vehicles, some heating, and parts of the rail network
- carbon capture and storage networks, which will be needed to decarbonise parts of industry, hydrogen production, electricity generation (from sources such as gas, waste incineration or biomass), and to enable engineered greenhouse gas removals.
While government has published strategies and business models for both networks, there are still many questions to be resolved. It is still to be determined how quickly these networks can be delivered, at what scale, and how plans can be coordinated.
In the second Assessment, the Commission will consider the rollout of these networks. The key challenge will be understanding what scale of networks will be necessary for both hydrogen and carbon capture and storage. This can be difficult to determine, as while hydrogen and carbon capture and storage are complementary networks (carbon capture and storage is needed to produce low carbon hydrogen from natural gas, for example), there will be some areas of the economy where they compete as routes to decarbonisation. For example, either hydrogen or current power sources combined with carbon capture and storage could be used to decarbonise steel production.
Hydrogen networks
Hydrogen currently plays an extremely limited role in the UK energy sector. However, it has the potential to be used widely across the economy.108
The UK currently produces an estimated 27 TWh of hydrogen. Almost all of this is produced using fossil fuels and is used predominantly in the petrochemical sector.109 Long term policies and infrastructure for hydrogen production and deployment will therefore be needed to deliver large volumes of low carbon hydrogen.
The government has recently committed to a target of 1 GW of hydrogen production by 2025, and 5 GW (42 TWh) of low carbon hydrogen production by 2030, in its Hydrogen Strategy.110 The strategy is an important milestone in the development of the sector. The Commission welcomes the commitments made in the Strategy, including the proposed development of technical standards to ensure that production of hydrogen is low carbon irrespective of the production method used.
A critical question is how to drive down the costs of hydrogen production and decide what and how infrastructure networks are established. Alongside the positive measures in the Strategy, there needs to be greater clarity on the funding models to secure the necessary investor confidence to scale production. It will also be important to consider who will foot the costs of the long term funding model, and to ensure they are distributed fairly.
In the second Assessment, the Commission will examine the uses of hydrogen across the economy, which technologies are best placed to produce it, the infrastructure required, and the policy and funding frameworks needed, focussing on the longer term picture. The Commission will evaluate the potential for hydrogen in the UK and the actions that need to be taken to maximise that potential.
Carbon capture and storage networks
Carbon capture and storage networks can play a range of roles to reduce emissions across the economy, for example by capturing the emissions from:
- industrial processes
- electricity generation, such as gas or energy from waste plants
- hydrogen production from reforming natural gas.
Carbon capture and storage infrastructure is also required for engineered greenhouse gas removals, which will be necessary to offset residual emissions from hard to abate sectors such as aviation and agriculture. Engineered greenhouse gas removals capture carbon either through the processing of biomass or directly from air to create negative emissions. Technologies to do this already exist but are not yet being used at scale in the UK or globally.111 In its report Engineered greenhouse gas Removals, the Commission recommended that government commit to deploying a range of engineered removals at megatonne scale by 2030.112
The government plans to deploy carbon capture and storage networks by 2030. It has recently increased its ambition from capturing and storing 10 MtCO2e a year by 2030, to 20-30 MtCO2e.113
In the second Assessment, the Commission will assess the actions needed to meet demand for carbon capture and storage networks. This will include whether the government’s current actions will deliver the capacity likely to be required. The Commission will consider what actions are needed – where, when and how infrastructure gets delivered – to ensure that access to transport and storage does not become a barrier to efficiently reducing emissions.
Challenge 4: Networks for hydrogen and carbon capture and storage – the Commission will assess the hydrogen and carbon capture and storage required across the economy, and the policy and funding frameworks needed to deliver it over the next 10-30 years.
2.7 Challenges for the second Assessment
As set out in this chapter, the key challenges the Commission will consider in the second Assessment related to net zero will be:
Challenge 2: Decarbonising electricity generation – the Commission will consider how a decarbonised, secure and flexible electricity system can be achieved by 2035 at low cost.
Question 8: What are the greatest risks to security of supply in a decarbonised power system that meets government ambition for 2035 and what solutions exist to mitigate these risks?
Challenge 3: Heat transition and energy efficiency – the Commission will identify a viable pathway for heat decarbonisation and set out recommendations for policies and funding to deliver net zero heat to all homes and businesses.
Question 9: What evidence do you have on the barriers to converting the existing gas grid to hydrogen, installing heat pumps in different types of properties, or rolling out low carbon heat networks? What are the potential solutions to these barriers?
Question 10: What evidence do you have of the barriers and potential solutions to deploying energy efficiency in the English building stock?
Challenge 4: Networks for hydrogen and carbon capture and storage – the Commission will assess the hydrogen and carbon capture and storage required across the economy, and the policy and funding frameworks needed to deliver it over the next 10-30 years.
Question 11: What barriers exist to the long term growth of the hydrogen sector beyond 2030 and how can they be overcome? Are any parts of the value chain (production, storage, transportation) more challenging than others and if so why?
Question 12: What are the main barriers to delivering the carbon capture and storage networks required to support the transition to a net zero economy? What are the solutions to overcoming these barriers?
Details on how to respond to the call for evidence questions are set out in chapter 5.
Next Section: 3. Climate resilience and the environment
Society and the economy depend on a healthy environment. But the climate is changing, and nature is declining at unprecedented rates. Infrastructure needs to adapt to the growing risks of extreme weather and contribute to wider environmental objectives including increased biodiversity, reduced waste, and cleaner air and water.
3. Climate resilience and the environment
Society and the economy depend on a healthy environment. But the climate is changing, and nature is declining at unprecedented rates. Infrastructure needs to adapt to the growing risks of extreme weather and contribute to wider environmental objectives including increased biodiversity, reduced waste, and cleaner air and water.
In the second Assessment, the Commission will focus on the following key challenges:
- asset management and resilience
- surface water management
- the role of the waste sector in the move to a circular economy.
Alongside these, the Commission will focus on reducing greenhouse gas emissions through the challenges set out in Chapter 2 and assess impacts on emissions and natural capital for all the recommendations made in the second Assessment. The Commission will continue to monitor the government’s progress against its previous recommendations to improve resilience across the regulated sectors and increase resilience to drought and to river and coastal flooding.
Box 3.1: Climate resilience and the environment are key themes for the Commission
The challenges of adapting infrastructure to climate change, supporting a healthy natural environment and minimising negative impacts all closely relate to the Commission’s strategic objectives, which are to:
- Support sustainable economic growth across all regions of the UK: Resilient infrastructure supports economic growth by continuing to provide critical services, including protection from natural hazards, despite the growing risks of climate change. Furthermore, nature, and the biodiversity that underpins it, ultimately sustains the UK economy.114 Infrastructure can therefore support growth by minimising its impact on the environment and protecting nature from pollution, waste and hazards.
- Improve competitiveness: Resilient infrastructure supports competitiveness by providing services to businesses, including access to domestic and international markets, despite the growing risks from climate change. It is also reasonable to expect stronger environmental standards across global supply chains in the future,115 in which case higher domestic standards, including for infrastructure, will enable UK businesses to compete internationally.
- Improve quality of life: A healthy natural environment is essential to quality of life.116 Infrastructure can protect the environment and society from pollution, waste and natural hazards. It can also enhance the environment through design and help people to access nature. However, infrastructure can also undermine quality of life by polluting the environment and damaging habitats and biodiversity.
- Support climate resilience and the transition to net zero carbon emissions by 2050: Even with ambitious efforts to reduce emissions, impacts from climate change are inevitable.117 Infrastructure must be resilient to current and future climate change risks, including infrastructure which supports the transition to net zero.
In the Commission’s social research, carried out in June 2021, respondents from across the UK ranked the environment as the most important factor to consider when planning for future infrastructure. The number of respondents who ranked this as their top priority increased since the first Assessment in 2017 by six percentage points.118

The Commission covers economic infrastructure within the UK government’s competence. Many areas of economic infrastructure are devolved, see Chapter 1. This chapter therefore focuses on areas within the UK Government’s competence.
3.1 Infrastructure resilience
Climate change will increase the challenge of resilience across sectors
Economic infrastructure has generally proved resilient to shocks and stresses over recent years.119 Figure 3.2 shows the change in service interruptions over time for sectors where data is available. This offers only a partial picture, with fewer energy supply interruptions over time, spikes in sewer flooding linked to extreme weather, and increased rail cancellations.

However, it will become harder to maintain and improve resilience in coming decades, as climate change increases risks to economic infrastructure. Key climate projections are for:
- wetter winters and more intense summer storms, which will increase the frequency of river and surface water flooding, and with heavy or long term rainfall likely to increase incidences of landslides or subsidence
- rising sea levels around the UK which, in combination with the increasing intensity of storms, will exacerbate coastal erosion and flooding
- drier summers, which will reduce the amount of water available and require between 3,500 and 4,000 million litres per day of extra capacity by 2050 to protect England from extreme drought (drought with a 0.2 per cent annual chance)
- heat increases, with the greatest warming occurring in the South East, and summer heatwaves becoming more common, putting more pressure on infrastructure assets.120

All infrastructure sectors must adapt as the incidence of extreme weather increases. The Climate Change Committee’s 2021 Climate Change Risk Assessment describes risks to infrastructure sectors that require further action, which include:
- risks to infrastructure assets and services, including:
- risks to transport from high and low temperatures, high winds, lightning, slope and embankment failure
- risks to infrastructure from coastal change, including transport and waste
- risks to infrastructure services from river and surface water flooding, including transport, electricity and wastewater treatment
- risks from cascading failures in infrastructure networks including energy, water, transport and digital.
- risks that infrastructure can protect society against, including:
- risks to public water supplies from reduced water availability
- risks from river and surface water flooding.122
Risks to infrastructure, society and public health from flooding and coastal change, water scarcity and pollution are highlighted in the Environment Agency’s third adaptation report to government.123 The government will set out progress in responding to identified climate risks, along with a monitoring and evaluation framework, as part of the next National Adaptation Programme due in 2023.124
Preparing for risks to infrastructure assets and services
Infrastructure owners and operators, regulators and government all need to prepare for climate risks. In its 2020 study, Anticipate, React, Recover, the Commission recommended:
- a comprehensive set of resilience standards developed by the government for the energy, water, digital, road and rail sectors, and supported by clear duties on resilience for infrastructure regulators
- regular stress testing by operators to understand the resilience of infrastructure systems and to identify and address vulnerabilities
- long term resilience strategies, developed by operators, with guidance and scrutiny from the regulators.125
The government published its response to the recommendations on 15 September 2021. It accepted the Commission’s recommendations on standards and stress testing in principle but said that decisions on implementation will be taken as part of the forthcoming National Resilience Strategy, expected in 2022.126
Renewable sources of electricity, like wind turbines and solar panels, are reliant on the weather, which means that extreme weather may present risks to generation. The Commission is working with the Met Office and the Climate Change Committee to develop a data set which can help test the resilience of future electricity systems to extreme weather events.127
However, there remain significant resilience challenges, particularly around asset management, that the Commission has not yet considered.
Resilience must be embedded in asset management approaches
Good asset management requires managing infrastructure assets so that they can deliver services in a cost effective and timely way.128 Government, regulators and infrastructure operators need to strike a balance between short term cost saving measures which could reduce resilience, and providing excessive resilience at high cost. This will be increasingly important for maintaining and improving resilience as pressures on assets increase. And different approaches may be needed to increase resilience to low probability, high impact incidents such as flooding, while also responding to the risk of accelerated deterioration from more gradual changes in weather conditions.
There is already concern about the condition of assets in some sectors. The UK is still reliant on infrastructure built during the nineteenth century, including roads, railways, tunnels and sewers. Some older components, such as railway earthworks and embankments, can be at greater risk of failure as they were not constructed to modern design standards of resilience to extreme weather.129 In the water sector, around 13 per cent of water pipes are over 100 years old,130 which may increase the risk of leakages and bursts. And there are concerns that maintenance and replacement is not keeping pace with the rate of deterioration for assets like water pipes and local roads.131 As climate change accelerates deterioration, the costs and challenges of asset management could increase.
In some cases, deterioration is not noticed until a failure occurs. However, better data and processing technologies, such as sensors, combined with predictive asset management models, could provide more detailed information on asset condition and performance, helping to prevent failures and better target maintenance interventions or renewals.132
Decision making frameworks can also undervalue maintenance and disincentivise good asset management. For example, funding for the Environment Agency’s maintenance budget has been agreed for varying periods of time from four year periods to annually.133 This can make planning for and undertaking maintenance of flood assets less efficient. By contrast, in the regulated water sector, Ofwat includes an allowance for maintenance capital expenditure over the five year Price Review period.134 Approaches like this could help decision makers value maintenance needs over a longer time period.
Challenge 5: Asset management and resilience – the Commission will consider how asset management can support resilience, barriers to investment, and the use of data and technology to improve the way assets are maintained.
Preparing infrastructure to protect society against climate risks
Infrastructure can protect society against drought and floods. While the UK currently has a water supply surplus of around 950 million litres per day above demand,135 hotter, drier summers will increase the risk of drought. And more than five million properties in England – around one in every six – are already at risk of flooding,136 with this number likely to increase due to climate change. Of those properties, over three million are at risk of surface water flooding, which is more than the number at risk of river and coastal flooding combined.137
In the first Assessment, the Commission recommended action to increase resilience to drought by halving leakage by 2050, implementing compulsory metering by the 2030s, and developing additional supply infrastructure and a national water transfer network.138 The government endorsed the Commission’s recommendation to increase drought resilience to a 1 in 500-year drought (0.2 per cent annual chance),139 and Ofwat required water companies to reduce water taken from the environment, leakage and household water consumption between 2020 and 2025.140 Ofwat has also allocated £469 million for companies to investigate and develop proposals for new strategic infrastructure to address long term drought challenges.141 In the South East, Portsmouth Water is already building the Havant Thicket reservoir which will provide around 21 million litres of water per day when finished, reducing drought risk in the wider region.142 The Commission will continue to monitor government’s progress on these recommendations but will not undertake new work in the second Assessment.
The Commission also made recommendations on floods in the first Assessment. It recommended that government develop a flood strategy to deliver a nationwide standard of resilience to coastal and river flooding with an annual likelihood of at least 0.5 per cent, or 0.1 per cent in densely populated areas, supported by a rolling six year programme of funding.143 The government has partially endorsed these recommendations. The March 2020 budget announced an investment of about £5.2 billion between 2021 and 2027 to protect against flooding in England, which further announcements have brought closer to £5.6 billion.144 While rejecting specific standards, the government committed to develop a set of indicators to measure improvements in resilience to flooding. The Environment Agency has revised its National Flood and Coastal Erosion Risk Management Strategy for England, and the National Planning Policy Framework has also been revised to clarify the approach to flood risk management in England.145 The Commission will continue to monitor government’s progress and hold government to account for delivering on its commitments, but will not undertake new work on river and coastal flooding in the second Assessment.
A lack of reliable data meant that it was not possible to consider surface water flooding or wastewater in detail for the first Assessment. The Commission instead recommended that all relevant organisations ensure that the necessary data be available for the second Assessment. The Commission will consider surface water management as part of its upcoming work.
Surface water management is a key challenge
Surface water flooding occurs when the volume of rainfall exceeds the capacity of drainage systems. Water cannot quickly drain away or soak into the ground. Instead, it collects at low elevations causing flooding. This type of flooding is often localised and is disruptive to homes and businesses. It can also cause serious pollution to rivers with impacts on water and environmental quality, biodiversity, and public health and amenities. The continued risks of surface water flooding were highlighted by incidents during the summer of 2021.146
The government is making piecemeal improvements,147 but the scale of the challenge may require a more fundamental review of current arrangements. Multiple organisations are currently responsible for assets that impact on surface water flooding including local authorities, highways authorities and water companies. Water company sewers have a key role to play in providing drainage and reducing the risks of surface water flooding – if capacity in the sewerage system is not available, then sewers overflow. Seven per cent of water bodies in England, such as lakes and rivers, are failing good ecological status due to intermittent stormwater overflows.148 While serious pollution incidents caused by water and sewerage companies decreased from 2002, they have plateaued since 2014 at an unacceptable level, and further action is needed to address this.149 And while properties are eight times less likely to suffer sewer flooding than they were in 1990, climate change could increase this risk.150
In the second Assessment, the Commission will carry out a dedicated study, as requested by government in the 2021 Spending Review, on reducing the risks of surface water flooding.151 This will undertake analysis to gain a better understanding of the challenge and the opportunities to address it in the short and long term. The Commission will determine the improvements needed to England’s drainage systems to manage and mitigate surface water flooding in urban and rural areas, both now and in the future. It will assess current approaches to manage surface water and consider which options provide the greatest resilience and value for money. This may include improving current levels of governance, performance, preparedness and understanding, local flood planning, spatial and development planning, data sharing, funding and investment. It will also include opportunities for harnessing nature based solutions, such as sustainable drainage systems, blue green infrastructure, and natural flood management, alongside hard engineering solutions that increase sewer capacity for new and existing developments.
Challenge 6: Surface water management – the Commission will consider actions to maximise short term opportunities and improve long term planning, funding and governance arrangements for surface water management, while protecting water from pollution from drainage.
The Commission will deliver this as a separate study and report to government by November 2022, in advance of its other recommendations.
3.2 Infrastructure and natural capital
Alongside climate change, there is another environmental crisis. Global assessments show that nature is declining at rates unprecedented in human history, with accelerating rates of species extinction and severe disruption to ecosystem services.152 Infrastructure contributes to this decline but can also help prevent it.
The decline in nature can be measured through impacts to ‘natural capital’. This term refers to the natural assets that society and the economy depend upon, including the atmosphere, forests, fisheries, rivers, biodiversity, land and minerals, and both the living and non-living aspects of ecosystems. These provide environmental services and benefits, such as food, timber, minerals, fresh water, clean air, and protection from flooding, drought, heatwaves and landslides. More detail on natural capital can be found in the Commission’s discussion paper Natural Capital and Environmental Net Gain.153
There is a two way relationship between infrastructure and natural capital:
- infrastructure can have a negative impact on natural capital assets, for example through air and water pollution, damage to habitats and biodiversity, or the extraction of minerals for construction
- infrastructure can deliver benefits for natural capital, for example by preventing harmful waste products from entering the natural environment, through the provision of protected natural habitats and connecting corridors for species along linear infrastructure, and the use of sustainable drainage systems for mitigating flood risk
- changes in the environment can increase the costs of infrastructure, for example if roads and railways need to withstand higher temperatures (see section 3.1)
- natural capital approaches can reduce the demand for infrastructure, for example natural water catchment management reduces demand for flood defences
- natural capital is a prerequisite for some infrastructure, such as inputs of freshwater to water supply networks – in these cases, the resilience of a sector is linked to the environmental service which underpins it.154
The government’s 25 Year Environment Plan sets out objectives to improve natural capital and ecosystem services.155 The Commission considered many of these objectives in its previous recommendations, as described in figure 3.4. Objectives on climate change are not included in this table, as they are covered in Chapter 2.

Natural capital in the second Assessment
In the second Assessment, the Commission will assess the impact of its recommendations on natural capital as part of its cross cutting analysis (see Chapter 5). It will also develop a set of natural capital principles for infrastructure which provide guidance on how best to deliver environmental net gain.
The Commission will consider specific environmental objectives through challenges in the second Assessment, including:
- clean air – the Commission will make further recommendations to reduce the impacts on air pollution from transport and energy (see Chapters 2 and 4)
- clean and plentiful water – the Commission will consider pollution from wastewater as part of challenge 6 (see above)
- reducing the risk of harm from environmental hazards – the Commission will make recommendations on surface water flooding as part of challenge 6 (see above).
In the second Assessment, the Commission will consider the objective on minimising waste in more detail. There has been some progress on this in recent years. The Commission’s recycling targets from the first Assessment were partially adopted in the Resources and waste strategy for England, albeit with a later target date of 2035.165 The government has committed to a national standard of recycling for households and businesses by 2025, and separate food waste collection (to enable biogas production) by 2025, as recommended by the Commission, and consulted on making producers responsible for the costs of managing packaging when it becomes waste. Some of these measures will be implemented through the Environment Act.166
However, as explained in Chapter 2, the net zero target means that the Commission will need to revisit its work on waste in the second Assessment. The government has also committed to move to a more circular economy, which could have wider implications for the sector.
The waste sector can protect the environment by enabling the move to a more circular economy
Waste infrastructure prevents harmful products from entering the natural environment by enabling the collection, sorting, treatment and disposal of waste. Recycling plays a central role by keeping materials in productive use, which reduces demand for the extraction of raw materials and the need for more carbon intensive and polluting forms of waste disposal. Recycling rates have increased since 2000, with 43 per cent of local authority collected waste in England recycled in 2019. Internationally comparable data is only available for the UK, rather than England, but the UK’s recycling performance is broadly comparable with similar countries. However, rates have stagnated in recent years.167
Figure 3.5. An international comparison of municipal recycling shows the UK lagging behind the best performers
Municipal recycling rates across comparative countries from 2008 and 2018
The government has framed its waste objectives as part of the move to a more circular economy. This concept refers to systemic changes across the economy which seek to:
- prevent waste by keeping products and materials in use for longer, favouring activities that preserve value in the form of energy, labour and materials, and designing for durability, repair, reuse and remanufacturing
- increase recycling to keep products, components, and materials circulating in the economy
- conserve natural resources by avoiding the extraction and use of non-renewable resources and promoting the use of renewable ones.168
The Commission’s social research suggests the public supports further action. Seven in ten respondents agreed that companies should take more responsibility for recycling and disposing of packaging waste, even if it raises the prices of products. Respondents also raised concerns around overconsumption, excess packaging, and the transparency of waste disposal processes.169
The Commission’s work will consider additional changes needed in the waste sector to enable the move to a more circular economy and reduce the environmental impacts of waste. This will include looking at ways to increase recycling rates for municipal and construction waste, deliver the infrastructure needed to achieve net zero, and increase resilience to possible future restrictions on waste exports. The Commission will also consider interdependencies with the other infrastructure sectors in its remit. This includes demand for energy and water, and the role of energy from waste. It also includes challenges and opportunities associated with construction waste from different infrastructure sectors as they take steps to improve resource efficiency and reduce waste.
This will require open and transparent data, for example on the capacity of recycling infrastructure. The government accepted the Commission’s recommendation in the first Assessment for a common data reporting framework for businesses that handle commercial and industrial waste. The Environment Act includes powers to introduce a digital system to track waste movements.170
Challenge 7: Waste and the circular economy – the Commission will examine the role of the waste sector in enabling the move towards a more circular economy.
3.12 Challenges for the second Assessment
As set out in this chapter, the key challenges the Commission will consider in the second Assessment related to climate resilience and the environment will be:
Challenge 5: Asset management and resilience – the Commission will consider how asset management can support resilience, barriers to investment, and the use of data and technology to improve the way assets are maintained.
Question 13: In what ways will current asset management practice need to improve to support better infrastructure resilience? Your response can cover any number of the Commission’s sectors.
Challenge 6: Surface water management – the Commission will consider actions to maximise short term opportunities and improve long term planning, funding and governance arrangements for surface water management, while protecting water from pollution from drainage.
The Commission will carry out a separate call for evidence on this challenge, as the Commission will deliver this as a separate study and report to government by November 2022, in advance of its other recommendations.
Challenge 7: Waste and the circular economy – the Commission will examine the role of the waste sector in enabling the move towards a more circular economy.
Question 14: What are the barriers to and solutions for expanding recycling capacity, both now and in the future to deliver environmental and net zero targets?
Question 15: What is the likely environmental impact of waste streams from construction across economic infrastructure sectors, over the next 30 years, and what are the appropriate measures for addressing it?
Details on how to respond to the call for evidence questions are set out in chapter 5.
Next Section: 4. Supporting levelling up
The government has set itself the ambition of ‘levelling up’ outcomes across the UK, reducing disparities between different towns, cities and regions. Infrastructure can support this goal. In the second Assessment, the Commission will examine the most significant unresolved infrastructure questions that relate to levelling up –focusing on the challenges of urban mobility and congestion, and interurban transport.
4. Supporting levelling up
The government has set itself the ambition of ‘levelling up’ outcomes across the UK, reducing disparities between different towns, cities and regions. Infrastructure can support this goal. In the second Assessment, the Commission will examine the most significant unresolved infrastructure questions that relate to levelling up –focusing on the challenges of urban mobility and congestion, and interurban transport.
Large cities and some towns outside London are not achieving their productivity potential. The reasons for this are varied and many have been entrenched for decades. Sustained local growth needs to be rooted in local strategies, covering a range of coordinated policy areas. While infrastructure is a necessary condition for economic growth, it is rarely sufficient. Instead, infrastructure should form part of wider economic strategies, alongside other areas like skills and inward investment.
Before the Covid-19 pandemic, many major cities suffered from congestion and poor public transport connectivity, preventing goods, services and people from travelling in an efficient and sustainable way. Overcrowded or slow transport networks limited the ability of businesses and workers to locate in dense city centres, which has been a major barrier to urban productivity and growth. Addressing this would benefit not just city centres but also their wider regional area.
Equally, the country’s interurban road and rail networks connect every city and town together, enabling people and goods to travel between them – ensuring that these networks are prepared for the demands of the future will help maximise their economic impact in every region.
Other infrastructure sectors also support productivity and wellbeing. Digital infrastructure can help improve productivity by improving connectivity, and new energy related industries, such as greenhouse gas removals or hydrogen production, may create economic opportunities for certain towns and cities, which could form part of locally led, wider economic strategies for those places.
4.1 Infrastructure and levelling up
The government has set itself the ambition of ‘levelling up’ outcomes between and within regions to improve opportunity and boost livelihoods.171 Levelling up has a variety of interpretations. Common to all of these is the aim to reduce disparities that exist between places.172 These disparities are driven by a mix of economic, social and political factors. There is no single policy area – including infrastructure policy – that can singlehandedly ‘level up’ a place. Infrastructure is necessary but not sufficient to support local economic growth, and infrastructure interventions should form part of a wider economic strategy.
Different places will always play different roles in the economy. The productivity potential of different places varies – different parts of the country have different economic densities. For example, it would not be realistic to aim for the same productivity in rural Cumbria as in central Manchester. But even narrowing economic disparities between places with comparable geographic characteristics would be a major success. While no two places are exactly the same, the Commission will look at broadly comparable places to assess their economic potential.
Levelling up the country should not be seen as an alternative to improving productivity nationally. The goal should be to support faster growth in lower productivity places, while maintaining or improving the economic performance of high productivity places.
Regional rebalancing must also not come at the expense of the commitment to achieving net zero. Improvements in transport connectivity must be delivered alongside reductions in carbon emissions, in line with the trajectory set out by the Climate Change Committee. Developments in some sectors, particularly energy, to deliver net zero may also provide new economic opportunities for some areas.
Many areas of economic infrastructure, including much of the transport sector, is devolved to Northern Ireland, Scotland and Wales (see Chapter 1). The Commission’s role is to advise the UK Government. This chapter therefore focusses on areas within the UK Government’s competence.
England has a wide and longstanding variation in outcomes
England has wide variations in economic outcomes and quality of life.173 Geographic variation in economic outcomes, in particular, is a long standing, self reinforcing problem that is complex to address.174 Infrastructure alone cannot address these problems.
Figure 4.1: Regional variation in productivity has endured over time
GDP per worker by region and nation in the UK relative to the UK average, 1901-2001
Source: Geary and Stark (2016), What happened to regional inequality in Britain in the twentieth century?
Productivity and wages, which are closely related, vary widely both within and across regions.175 As similar types of people and businesses tend to cluster together, some variation between places is inevitable, and many other countries also face persistent economic variation between regions. However, the extent of regional variation within England appears to be unusually high compared to other countries.176 England is also unusual in that few of its major cities, apart from London, have productivity above the national average.177

Disparities also exist within regions. Rural areas often have low productivity, while all regions have some hubs of manufacturing or knowledge intensive services with higher productivity such as those in Cheshire, Sunderland and York.178 There are disparities within cities too: in Greater Manchester, productivity in Trafford is over a third higher than in Oldham.179
Figure 4.3: There are wide differences in productivity among local areas in the UK

There are also disparities in quality of life between and within places. London and the South East score highly for healthy life expectancy, but London is lowest for life satisfaction. In London, only 26 per cent of people have a very high level of satisfaction with their life compared with consistent scores between 30 and 32 per cent in all other regions. Healthy life expectancy is lowest in the regions of the North.180
Box 4.1: The Commission's objectives and levelling up
Supporting levelling up aligns with all four of the Commission’s objectives, which are to:
- Support sustainable economic growth across all regions of the UK: By supporting growth in lower productivity places while maintaining or improving the economic performance of higher productivity places, reducing disparities between places will support sustainable economic growth across all regions of the UK.
- Improve competitiveness: Improving access to markets, labour and capital, either through transport or digital connectivity, can improve competitiveness. And contributing to the economic transformation of places through infrastructure investment can support both levelling up and competitiveness, if it leads to the development of new globally significant clusters and assets.181
- Improve quality of life: Infrastructure interventions to support levelling up can directly contribute to higher quality of life in places with poor provision – for example by connecting people to services concentrated in cities, reducing air pollution, and improving reliability of services. Contributing to improved economic outcomes will also support improved quality of life in some places.
- Support climate resilience and the transition to net zero carbon emissions by 2050: Ensuring universal provision of infrastructure such as flood defences and water supply can support both levelling up and climate resilience.
The Commission’s social research found that a quarter of people surveyed prioritised infrastructure driving regional growth and rebalancing growth more fairly across the country as one of the most important goals for the ‘vision’ of the UK’s infrastructure in 30 years’ time.182
Variations are caused by multiple interacting factors
There are several factors that interact to create self reinforcing cycles of economic success or deprivation in different places.183 Highly skilled people and businesses tend to cluster together, making individuals more productive and able to earn higher wages.184 Businesses in highly skilled sectors also tend to cluster together, making them more productive. Highly skilled workers also attract highly skilled businesses and vice versa. This effect is known as ‘agglomeration’.
These clusters also attract other high end businesses that concentrate in areas where there are well paid people who can pay for their services. The availability of these amenities and other services attracts other highly paid people. This high demand pushes up property prices in the area, further concentrating higher paid workers, and pricing out people with lower incomes.185
These effects also work in reverse. People on low incomes are likely to move to areas with low property prices and more affordable shops and services, clustering people on lower incomes and businesses that employ lower skilled workers.186
Some cities have gained from these agglomeration effects as the economy has shifted towards highly skilled services,187 while low incomes have persisted in some struggling areas.188 Towns near to productive cities tend to have higher incomes than those near less productive cities.189 Certain geographical characteristics can also increase the attractiveness of some places for new and growing industries. For example, the offshore wind industry is centred in windy coastal places near the North Sea, offering opportunities to Hull, Grimsby and the North East.190
Current variations may not continue. New technologies that lead to the development of new industries (for example the transition to decarbonised energy, see chapter 3), or changes in how work is done, for example increased levels of working from home driven by digital technologies and following the Covid-19 pandemic, may change current patterns of where people and businesses choose to locate.191
Variations in economic outcomes also influence the quality of life of people living in these places. Employment status is a strong predictor of life satisfaction,192 and the economic fortunes of an area influence a wide range of outcomes that impact how happy people are.193 Patterns of local productivity shape an individual’s quality of life, view of the world (including perceptions of other regions), and opportunities, which can differ profoundly between low and high productivity places.194 However, a good quality of life reflects a broad range of factors, including relationships, health, education and economic outcomes.195 Quality of the built environment, access to green space and sense of community all influence how happy people are,196 and some places, such as London, perform well overall on economic outcomes but poorly against some quality of life metrics.197 In order to improve all areas of quality of life policymakers also need to look at other causes.
Addressing these disparities is hard
Addressing variations in economic performance and quality of life is not straightforward. There is a long history of government attempts to address geographical variation in economic outcomes, with at best mixed success.198
Sometimes interventions move economic activity from one place to another, rather than increasing total activity – an effect known as ‘displacement’. Shifting economic activity from a relatively successful place to a less successful one might be worthwhile even if there is no net gain, but evidence suggests that displacement instead often shifts activity from one struggling area to another.199
There is also an element of luck in whether any particular attempt is successful. Successful place based policies elsewhere have brought infrastructure decisions into wider economic strategies that include issues like skills and industrial policy.200 These strategies work best with governance at the level they are intended to influence.
Places also need private sector investment to successfully level up. Successful long term infrastructure strategies can help attract private investment by giving investors confidence that their investments will be aligned with any new or improved infrastructure that industry may require. These strategies work best when governance is at the level they are intended to influence.201
Infrastructure can help address these disparities
The Commission has set out its view on how infrastructure can support growth and levelling up in Growth across regions.202 This discussion paper identified three pathways for infrastructure to help achieve economic outcomes in different areas:
- Addressing constraints to growth: Enabling future growth in congested places by investing in transport capacity upgrades. This allows greater clustering, by facilitating greater density in these areas. These interventions primarily support growth in dense places with high productivity potential (primarily cities), furthering the virtuous cycle of agglomeration, although surrounding towns also benefit from increased growth in cities.203
- Contributing to transformation: Prioritising infrastructure investment alongside wider policies (e.g. skills, research and development) to increase growth in low productivity places, with an emphasis on promoting a positive cycle of investment and growth. This could include investing in the infrastructure required to enable new and emerging industries to expand in a specific location or improving connections from towns into their nearest city.204
- Universal provision: This involves setting common or minimum standards for infrastructure services and working to reduce differences in access across the UK. These interventions will contribute to improvements in quality of life, resilience to shocks, and other societal outcomes.
Supporting growth across regions can also help improve quality of life, as economic outcomes are one driver of quality of life outcomes.205 However, infrastructure interventions can also directly contribute to higher quality of life in places, for example by connecting people to services concentrated in cities, reducing congestion and pollution and improving reliability of services. The Commission will explore this relationship further in its forthcoming discussion paper on its quality of life objective and will use this to consider infrastructure’s role in improving quality of life outcomes in the second Assessment. The Commission has already published a literature review, which sets out the evidence base on the interaction of infrastructure and quality of life.206
While better infrastructure can benefit both productivity and quality of life, the largest and most regionally significant projects are likely to impact on outcomes primarily through improving economic opportunity. The Commission will take account of where places are not reaching their economic potential to identify where interventions are likely to deliver significant benefits – for example identifying where growth could be unlocked by increasing capacity in congested city centres – and then consider how the required interventions can improve both productivity and quality of life.
Infrastructure interventions are also likely to have the most impact in places where population concentration creates high demand, so there is a relationship between infrastructure and housing. The Commission considers the potential interactions between its infrastructure recommendations and housing supply, but housing policy itself is not in its remit.
Locally led infrastructure strategies should form part of wider economic plans
While infrastructure has an important role to play in supporting economic growth and quality of life, and thereby reducing disparities between places,207 it is not the whole solution. Other factors, like skills and education, also have an important role in delivering economic and quality of life outcomes, and therefore need to be aligned to infrastructure investment.208 And for investments to be most effective, investment decisions need to be taken at the right level, and ensure all interventions work together for different places. For infrastructure to best support levelling up, the Commission has identified three key conditions:
- infrastructure strategies should form part of wider economic strategies
- cities and towns should have devolved powers and funding to develop locally led infrastructure strategies, with central government oversight reserved for only the biggest projects
- government should make expert support and advice available to help those local authorities where capacity and capability are obstacles to developing and delivering their infrastructure strategies.
The first Assessment recommended that cities should have the powers and funding they need to pursue ambitious, integrated strategies for transport, employment and housing.209 And in Infrastructure, Towns and Regeneration, the Commission concluded that the present funding system for local transport hinders the development of effective strategies and plans.210 To address this, the Commission recommended that central government simplify these funding streams and provide county councils and unitary authorities responsible for strategic transport planning with devolved five year budgets for local transport.211
Improvements in the transport sector can have the greatest impact
While all infrastructure sectors support productivity and quality of life, some have greater potential to play a role in reducing disparities than others.
Transport is the sector with the most opportunity for helping to reduce disparities between places. Transport can help address constraints to growth and, with the right conditions, contribute to economic transformation in particular places.212 Larger cities in particular suffer from congestion, and some places have poorer interurban connectivity than others.213 Transport connections can increase the density of high productivity clusters of people and businesses in cities, facilitate trade between cities, make places more attractive to live and work in, and encourage investment in places.214 Effective distribution of freight is also essential to growth in any area.215 However, transport is not the whole solution – transport investment needs to come alongside other investments as part of a wider economic strategy in order to contribute to transformation.
Although airports can have an impact on economic outcomes – they facilitate global trade, provide jobs, and can be globally significant assets – any consideration of aviation and levelling up is dependent on future demand for air travel following the Covid-19 pandemic, and the approach to expanding runway capacity in the South East, which is currently unclear. The second Assessment will therefore not further consider airport capacity, although interurban connectivity to international gateways will be included.
Digital connectivity plays an increasingly important role in society and the economy, by increasing the economic reach of local businesses, enabling new ways of working more productively, and enhancing connectivity to support quality of life.216 While variations between regions exist, government has a clear strategy to deliver near universal coverage of gigabit broadband and mobile 4G,217 though it remains critical that this is effectively rolled out to rural areas and towns to ensure genuinely universal provision. The Commission will continue to monitor progress in these areas.218
Energy is a universal service and spatial variations are not a key driver of productivity disparities.219 However, new energy related industries and zero carbon infrastructure, may create economic opportunities for certain towns and cities, which could form part of locally led wider economic strategies for those places. There may also be areas that are reliant on carbon intensive industries from which they will need to transition away from, and doing this may have short or longer term impacts on their local economies.
Other infrastructure sectors can be important to growth and quality of life but are not considered in this chapter:
- flood resilience is vital to economic growth and quality of life, but can vary by area – in the first Assessment, the Commission recommended a nationwide standard of flood resilience – the government partially endorsed the Commission’s recommendations (see Chapter 3 and Annex C), and the Commission will continue to monitor government’s progress
- water and waste are universal services where coverage does not vary significantly, or where variation does not significantly affect productivity.220
4.2 Transport and levelling up
Transport provision varies between places
Many cities and regions suffer from poor public transport connectivity, which creates barriers to mobility and impacts on quality of life.221 Before the Covid-19 pandemic, many major cities suffered from congestion, especially in the largest cities and at peak times.222
Transport connectivity represents how quickly it is possible for people to travel from where they live to other places they might need to go. The Commission has developed a metric to illustrate the effectiveness of the transport network at moving people by car and public transport, both within built up areas (urban connectivity) and between them (interurban connectivity), with higher scores indicating better connectivity.223 Congestion can be calculated by the ratio between peak and off peak connectivity.
Larger cities tend to have worse congestion and poorer connectivity
The effect of peak time congestion means that transport connectivity is worst in the largest built up areas. In towns with a population of under 100,000, connectivity at peak times has typically been around 10 per cent worse than off peak travel, and virtually never more than 20 per cent worse – illustrated by the congestion graph in figure 4.4 (where a score of 0.8 means that congestion reduces connectivity performance by around 20 per cent). It is only cities of more than about half a million people that see the most serious congestion effects, with connectivity 40-50 per cent worse at peak time. These congested cities are spread through the regions of the country – of the ten most congested cities outside London, three are in the North, three are in the Midlands, two are in the South West and two are on the south east coast.224
Figure 4.4: Urban transport connectivity tends to be worse in larger towns and cities, due to the effects of congestion

This urban congestion is a product of the density in population and employment required for successful cities.225 This most obviously manifests on roads, where delays are caused when there are too many cars for the space available. Public transport is an essential alternative to car travel in places that suffer from congestion, but, without the right infrastructure, congestion also affects how transit services operate, with buses stuck in traffic and trains overcrowded. Freight deliveries also suffer from congestion on roads and cannot easily be replaced with off road alternatives.
As cities grow, transport capacity can struggle to keep pace with demand, creating a constraint on further growth. People are only willing to commute for a certain amount of time, on average around half an hour each way per day.226 The impacts of congestion on travel times in cities therefore limits both the number of jobs available to people looking for work and the number of potential employees for businesses to recruit from. Not only does this reduce the productivity and wages of people and employers directly affected – slowing down the positive cycle of agglomeration effects set out in section 4.1 – but its effects ripple out into the surrounding region, since more productive activity within cities can create more demand for other services that can be provided from towns nearby.227
Figure 4.5: Public transport can provide much higher transport capacity than cars, enabling higher density employment in city centres, even if they are congested
Typical maximum capacity per lane (inbound passengers per hour)
Source: National Infrastructure Commission (2018), National Infrastructure Assessment
The Covid-19 pandemic initially reduced congestion in cities, as stay at home guidance meant people made fewer trips by car. Public transport use also fell by 80 to 95 per cent, and government gave emergency financial assistance to avoid the collapse of transport providers.228 However, congestion had already returned to high levels on urban roads by the time of the latest data in February 2021,229 while lockdown restrictions were still in force, and is likely to have increased further as motor traffic has more recently reached close to pre pandemic levels.230
Nevertheless, there remains scope for more significant longer term changes, and it is too early to make confident forecasts for infrastructure demand for the long term. Policy proposals for public transport investments will take into account the need to plan for, and remain responsive in implementation to, the range of possible future scenarios.
Plans for urban transport will also need to address carbon emissions. In the long run this will mean full electrification of cars as well as zero emission upgrades for buses, goods vehicles and trains. On-street charging for cars is a particularly significant issue in cities where many people do not have a driveway. The Commission’s recent report Infrastructure, Towns and Regeneration recommended that government publish the electric vehicle charging infrastructure strategy, followed by a roadmap for the rollout of electric vehicle charging infrastructure in towns, and that local infrastructure strategies include an active role for the local authority in planning and managing the rollout of on street electric vehicle charging.
In the shorter term, before electrification of cars is complete, enabling people to use public transport or active travel as an alternative to driving provides an opportunity to reduce emissions. While the switch to electric vehicles will have significant environmental benefits, it will also have significant fiscal consequences due to loss of fuel duty.
Public transport and demand management can help address congestion
Increasing public transport capacity is one option to address congestion – either by enabling car travel to be replaced with more space efficient buses or trams, or by providing more space on faster rail connections from places further out. Successful cities are likely to remain congested to some degree, even with the very best infrastructure, as more people come and use the additional capacity, and some people will always prefer to travel by car. But increasing the number of people who can commute in is necessary to support the higher densities of businesses and workers in city centres and enable agglomeration benefits.231
Another option to reduce crowding on roads is demand management – which could include congestion charging for city centres, or other measures to restrict car access to certain areas. These measures could reduce overall use of cars, resulting in either less congestion or an opportunity to reallocate road space to other purposes. Congestion charging would also provide a new source of revenue to support public transport and help to ensure motoring taxes keep pace with the transition to electric vehicles. However, if public transport provision does not offer a genuine alternative to driving, restrictions on road use could have a negative impact on economic outcomes.
Approaches to congestion charging and wider questions of ‘road pricing’ can be sensitive, as there is an assumption that the public are inherently opposed to such models.232 Given the challenges set out above, the Commission is keen to support an evidence based discussion of the options, helping to open up debate and allow proper consideration of the costs and benefits of different approaches.
As a starting point, the Commission has used deliberative engagements in three cities across England to explore public attitudes to tackling urban congestion, see box 4.2, which found a higher than expected level of support for congestion charging.
Box 4.2:Deliberative engagements on tackling congestion
In early 2020, the Commission ran three deliberative engagements on urban congestion with members of the public in Bristol, Nottingham and Manchester.233 The Commission assembled a panel of experts from all sides of the debate, including the RAC and the Campaign for Better Transport, to review an evidence pack on the causes and impacts of urban congestion. The Commission also appointed an independent evaluator to assess the fairness of the exercise. Participants in each location were then given two days to consider the evidence, speak to experts, and discuss potential packages of responses, including accepting congestion, congestion charging, and investing in public transport.
Across all three groups, despite initial opposition, at the end of day two congestion charging was identified as at least part of the solution by 82 per cent of participants. After considering the evidence, participants felt that continuing with high congestion was not an acceptable option and that investing in public transport on its own would not be sufficient to reduce congestion. While this was a very small sample size, it does suggest that citizens are potentially open to congestion charging as part of the solution. The Commission’s recent national survey of more than 6,000 participants also found 40 per cent of participants were willing (compared to 30 per cent unwilling) to accept congestion charging if proceeds supported public transport investment.
The first Assessment recommended long term locally led investment in urban transport to allow greater density in city centres. The Commission also set out principles and case studies for local infrastructure strategies and the devolved governance that should enable them to happen,234 and highlighted that suburban towns may experience greater economic opportunity if they were better connected into city centres.235
The government has made some progress in this area, committing £5.7 billion for intraurban transport settlements between 2022 and 2027 in eight out of the nine mayoral combined authorities outside London,236 with funding allocated on a more stable basis than before. Government also wants half of all journeys in towns and cities to be made by walking or cycling by 2030 – although walking and cycling will be more feasible in some places than others. Government has committed £5 billion over the current parliament for bus services and cycling,237 with a new inspectorate to oversee spending and standards, and a second Cycling and Walking Investment Strategy due this year. In addition to the reforms set out in the National Bus Strategy, it has also committed to support local authorities to build business cases and develop innovative sustainable transport policies.238
However, government’s current commitments may not be sufficient to deliver levelling up. There is currently no pipeline of urban transport projects at the scale likely to be required in coming decades to address the impacts of congestion on growth and productivity in the busiest cities with the most growth potential. Previous analysis undertaken by the Commission suggests that investment in the region of tens of billions above planned investment will be needed, unless transport patterns following the Covid-19 pandemic are significantly different – enough to fund a wave of very large transport projects such as new tram lines and more urban rail capacity across a number of cities.239 Part of this would be funded from locally raised income – in 2019-20, around £2 billion of local transport investment was funded in this way.240
Challenge 8: Urban mobility and congestion – the Commission will examine how the development of at scale mass transit systems can support productivity in cities and city regions and consider the role of congestion charging and other demand management measures.
There are wide variations in interurban connectivity
There are wide variations in interurban connectivity between places. However, it is hard to discern clear patterns in the variation, or identify why they exist. Figure 4.6 shows how interurban connectivity performance, by both car and public transport, varies among built up areas in comparison to their population size. Variation in interurban connectivity is not neatly explained by the size of a place as it is for congestion – large and small settlements both show significant variation. However, it is clear that public transport journeys are significantly slower than those by car, although scores again vary among places of similar sizes.

Similarly, there is not a clear regional pattern in interurban connectivity, see figure 4.7. There is a wide variation in performance among places in all regions in England. However, it is clear that transport provision is poor in many places. Around 30 per cent of people living in towns say that they are unsatisfied with road services where they live.241 The Commission noted in its Rail Needs Assessment that rail journeys between major cities in the Midlands and the North tend to be slower than those in London and the South East, and slower than those in high productivity regions in the Netherlands and Germany, particularly for short rail journeys.242 The study also identified issues with rail reliability and overcrowding in the Midlands and the North that need to be addressed.

Improving interurban transport may also be able to support levelling up
Improving interurban transport – for cars, public transport passengers and freight – can facilitate trade between cities.243 It can enable businesses to source a wider range and better quality of inputs to their supply chains by reducing the cost of distance. It can also increase the size of market that any one provider can access, allowing successful firms to grow, benefit from economies of scale, and potentially specialise in higher value niche services that would be uneconomic in smaller markets – further supporting the potential for agglomeration in specialised clusters. In turn, this increases the incentives on workers to specialise and upskill.244
It can also make places more attractive to live and work in and, in the case of large investments such as high speed rail, facilitate investment. Infrastructure can act as an anchor investment, signalling to the market that locations are worth investing in, because other people or businesses are also likely to move there – for example, major stations and interchanges of nationally significant infrastructure projects offer significant potential for urban regeneration. These major investments should maximise the potential for urban regeneration. This helps to solve coordination problems where the value of private sector investment depends on other investors making similar choices.245 New infrastructure can help provide confidence that particular areas will be suitable for the changing needs of new industries.
Government is making major investments in interurban transport, through the Road Investment Strategy, High Speed 2, and ongoing upgrades to the rail network. Investment in national roads is planned to increase by more than double between 2015-16 and 2024-25, while investment in rail is planned to increase by more than half over the same period.246 This makes it vitally important that there is a comprehensive and strategic understanding of what the priority objectives and projects should be within this investment.
Whilst there is variation in connectivity between places it is difficult to assess the relative impact this has on productivity and quality of life in different places that all have different economic strengths. Whilst the Commission’s data reflects the current connectivity of the transport network, technological innovation, decarbonisation and behaviour change are also transforming the sector – electric and autonomous vehicles create new opportunities and challenges for managing the road network, while improved digital connectivity has the potential to transform patterns of commuting and service delivery. The long term impacts of the Covid-19 pandemic are also uncertain.
A multimodal transport strategy can improve coordination and prioritisation of investment
In transport policy, governance and funding tends to be considered in siloes for the different modes of transport.247 Therefore, it can be difficult to determine the optimal balance of investment between different places and modes in terms of boosting growth and productivity, improving quality of life and achieving net zero. A multimodal transport strategy for interurban connectivity could help the country plan more effectively for sustainable growth and the shift to net zero, optimising the use of different modes and covering both accessible passenger and freight transport. Any multimodal transport strategy would need to be coordinated with locally led infrastructure strategies, as recommended by the Commission in previous reports.
Planning across modes and regions would help understand the priorities for improvement and how to address them, including which places are underperforming most on connectivity measures, and which have the greatest economic potential for infrastructure to unlock.248 It would also enable a full understanding of the costs and priorities for delivering net zero, including electric vehicle charging to enable rapid transition to zero emission cars, emission free technology for trains, coaches and goods vehicles, and an understanding of the extent to which demand management may be necessary in the period before all cars are electric in order to comply with the sixth carbon budget.
In the second National Infrastructure Assessment the Commission will therefore seek to better understand the long term needs of different cities and regions in terms of how interurban transport can impact on productivity and quality of life.
Challenge 9: Interurban transport across modes – the Commission will consider relative priorities and long term investment needs, including the role of new technologies, as part of a strategic multimodal transport plan.
4.3 Digital
Digital infrastructure and the use of data are important contributors to economic opportunity and quality of life, through improved connectivity and new use cases which may boost local economic performance.249 In some places digital connectivity may serve as a substitute for transport connectivity. Digital services may be increasingly important for access to work and in determining where people choose to live, if increases in working from home induced by Covid-19 endure in the long term.250
In the first Assessment, the Commission recommended that government should start work to ensure nationwide full fibre coverage by 2033.251 To support that ambition, it recommended that the government develop a national broadband plan by the end of 2018, and to subsidise full fibre rollout in areas where it may not be commercially viable.
Since the first Assessment, the government has set an ambitious target to reach at least 85 per cent gigabit broadband coverage by 2025,252 and to move towards universal coverage as soon as possible. Gigabit coverage is intended to provide a service as fast as full fibre, but in some cases using alternative technologies to achieve this goal. Good progress is being made so far on commercial rollout – over fifty per cent of premises are now able to access gigabit capable broadband.253
Achieving nationwide gigabit broadband coverage is a major civil engineering challenge and will require a significant level of private investment. The government’s target is achievable as long as the policy and regulatory environment remains pro investment and network operators deliver against the plans they have set out. For premises in harder to reach areas, the government will, where necessary, subsidise delivery using public funds through the Project Gigabit Programme.254 The Commission will monitor progress with the rollout of gigabit capable broadband against government’s targets.
On mobile coverage, 92 per cent of the UK landmass is covered by at least one mobile operator, with a funded plan to increase this to 95 per cent by 2025.255 The Shared Rural Network agreement between government and the mobile operators should expand signal coverage and close almost all ‘partial not spots’ – areas where there is currently only signal from at least one but not all operators.256 However, data based on real user experiences suggests there may be issues with 4G availability in certain places.257
In its recent study on Infrastructure, Towns and Regeneration, the Commission recommended that central government take measures to address any gaps in gigabit broadband coverage in towns and develop with Ofcom a more granular picture of mobile user experiences.258 The Commission also recommended government develop a strategy to encourage the take up of new communications networks and services, including supporting innovation pilots.
As set out in chapter 1, in the second Assessment the Commission will explore how the adoption of digital technologies and use of data, enabled by these networks, can improve the supply of and reduce demand for infrastructure across sectors.
4.4 Energy
Energy is a universal service which almost all areas of the country have access to:
- nearly all properties are attached to the national grid for electricity259
- 85 per cent of properties are attached to the gas network.260
For some areas, new energy infrastructure may create new economic opportunities. The transition to net zero will require investment in new industries, such as greenhouse gas removals, carbon capture and storage and hydrogen production. This may create economic opportunities for certain towns and cities – especially where growing industries are clustered together, as identified in the Humber local industrial strategy – and which could form part of locally led wider economic strategies for those places.261 The development of the offshore wind sector has already created new opportunities for coastal towns close to large wind farms, such as Grimsby.
In the Commission’s Infrastructure, Towns and Regeneration report, the Commission examined the impact of this potential transformation on Grimsby and made recommendations about how infrastructure policy could help similar places seize the opportunities of the energy transition. However, the transition away from oil and gas may have the opposite effect in places where these industries are centred, such as Aberdeen or Shetland.
The transition to net zero also requires individual households and businesses to take action, both to improve the efficiency of their buildings, and to transition to low carbon heating and cooling solutions. Spatially, energy efficiency varies from building to building, meaning some properties will have higher energy bills than others, affecting quality of life.262 This means that the task of transitioning to zero carbon energy will require different interventions and generate different opportunities in different areas. Areas of the country with older housing stock may need significantly more investment to retrofit energy efficiency improvements.
The Commission’s Infrastructure, Towns and Regeneration study discussed how some areas may be able to use infrastructure planning to make the most of the opportunities of decarbonisation.263 Building on this previous work, the Commission will further explore energy related challenges and the transition to net zero as set out in chapter 2. As part of this work the Commission will identify differing spatial effects and whether they could support levelling up.
4.5 Challenges for the second Assessment
As set out in this chapter, the key infrastructure challenges the Commission will prioritise in the second Assessment with respect to levelling up will be:
Challenge 8: Urban mobility and congestion – the Commission will examine how the development of at scale mass transit systems can support productivity in cities and city regions and consider the role of congestion charging and other demand management measures.
Question 16: What evidence is there of the effectiveness in reducing congestion of different approaches to demand management used in cities around the world, including, but not limited to, congestion charging, and what are the different approaches used to build public consensus for such measures?
Challenge 9: Interurban transport across modes – the Commission will consider relative priorities and long term investment needs, including the role of new technologies, as part of a strategic multimodal transport plan.
Question 17: What are the barriers to a decision making framework on interurban transport that reflects a balanced approach across different transport modes?
Details on how to respond to the call for evidence questions are set out in chapter 5.
5. Next steps
5.1 The route to the second Assessment
The second National Infrastructure Assessment will be published in the second half of 2023 and will set out long term infrastructure needs and recommendations to meet them in the next 10-30 years. This National Infrastructure Baseline Report has set out the current state of economic infrastructure, identifying nine key challenges the Commission will consider for the second Assessment, falling under the three strategic themes covered in Chapters 2-4.
The second Assessment will set out recommendations to address these key challenges. This document contains call for evidence questions on the key challenges to support the Commission as it develops its work for the second Assessment. Details on how to respond to the Call for Evidence are set out at the end of this chapter.
In the run up to the second Assessment, the Commission will use the Call for Evidence responses and evidence gathered through stakeholder engagement, social research, and advice from experts to inform the development of its recommendations to government.
Figure 5.1: Timeline for the second Assessment
Principles
Alongside the Commission’s objectives, the following principles – based on the Process and Methodology Consultation conducted before the first Assessment – will underpin the Commission’s work for the second Assessment:
- Open, transparent, engaging with a wide range of stakeholders: The Commission will seek to capture the expertise and opinions of people from across infrastructure providers, business, central and local Government, academia, civil society and the wider public.
- Independent, evidence-based, objective and rigorous: The Commission will seek to form a clear, dispassionate assessment of the UK’s infrastructure needs, built on extensive expertise and a robust methodology.
- Forward looking, challenging established thinking: Rapid changes are happening in technology, and people’s behaviour is also changing – especially as a result of the Covid-19 pandemic. These changes create challenges and opportunities for the UK. The Commission will seek to assess the impact of technology, behaviour change and other factors on the supply of and demand for infrastructure services and look to make recommendations which are affordable in and robust to multiple future scenarios.
- Comprehensive, taking a whole system approach, understanding and studying interdependencies and feedbacks: The Commission will seek to assess the UK’s infrastructure system as a whole, looking across sectors, and identifying and exploring the most important interdependencies and resilience implications.
The independence of the Commission from both government and industry will enable it to develop a strategy that is in the long term interests of the UK’s present and future population. The wide ranging engagement and evidence gathering processes that underpin the Assessment aim to increase transparency and secure a broad consensus around its recommendations, including from all sides of the political spectrum.
Stakeholder engagement and expert advice
The Commission will engage widely in the run up to publication of the second Assessment to inform its work on the nine challenges outlined in this report. This includes engagement with industry bodies, business and not for profit organisations, including through responses to the Call for Evidence contained in this report. The Commission will also further research the views and preferences of the public to shape its recommendations.
The Commission will also hold a programme of roundtable events to explore policy questions in detail with regional and sectoral stakeholders. This will involve Commissioners meeting with local businesses, representative groups and politicians across the country, and events bringing together a wide range of stakeholders with interests in the three strategic challenges and the sectors within the Commission’s remit. A second round of similar events will take place later in the policy evaluation process.
To help inform the second Assessment, the Commission has established three expert advisory panels – on net zero, climate resilience and levelling up – that have advised on the development of this Baseline Report. The panels will continue to offer expert advice, support analysis, contribute new ideas and insights to support recommendations, challenge the Commission’s thinking, and offer alternative perspectives. The membership of each panel can be found on the Commission’s website.264
The Commission’s work for the second Assessment will also draw on the advice of the Commission’s Design Group. The Design Group was established in 2019 to champion design excellence in national infrastructure. It published the Design Principles for National Infrastructure in February 2020 which sets out four design principles – climate, people, places and value – that should guide the planning and delivery of infrastructure projects.265
To provide fresh thinking and ensure that the next generation will be sufficiently represented, the work of the Commission’s Young Professionals Panel will support and inform the second Assessment. The Panel was established in 2018 to ensure a strong voice for the next generation of infrastructure leaders in the Commission’s programme.266
The Commission’s website will be updated regularly with information on how stakeholders can engage in the process. Stakeholders will also be able to register to receive updates on progress towards the second Assessment, and opportunities to get involved, by signing up for email alerts via the Commission’s website.
5.2 Developing recommendations
Managing uncertainty
There are several external factors that impact the supply and demand of infrastructure, including the environment and climate change, population and demography, technological change, economic growth, and behaviour change following the Covid-19 pandemic. In particular, the long term effects of the pandemic have highlighted the uncertainty that will be present when the Commission comes to develop the second Assessment. The Commission’s report Behaviour change and infrastructure beyond Covid-19 describes how the spread of potential outcomes for transport – particularly public transport – is wider than for other sectors, although all sectors will face challenges.267
The Commission will develop scenarios for the second Assessment to explore how the key drivers may affect the future supply and demand of economic infrastructure, including using those set out in Behaviour change and infrastructure beyond Covid-19. These scenarios will be published in spring 2022.
The Commission takes a range of approaches to managing the uncertainty around future trends that impact infrastructure, to ensure that its recommendations stand the test of time as far as possible. As set out in the first Assessment, these approaches include:
- Balancing the risks of major investments, prioritising investments where the potential costs of inaction are higher than those of action, such as increasing the water supply to prepare for droughts, but taking a more ‘adaptive’ approach where it is possible to make changes incrementally as the situation develops – for example in flood defences.
- Making complementary recommendations, such as investing in both urban transport and rural fibre to mitigate uncertainty about where people will live and work in future.
- Planning for future decisions, for example by trialling options for low carbon heat to improve the evidence base for decarbonising heat over the 2020s.
The Commission will continue to follow these approaches in the second Assessment. While the infrastructure industry requires as much certainty as possible, sometimes plans will need to be changed as more evidence emerges. Adaptive frameworks will therefore continue to be particularly important for the Commission in managing these trade offs.
Analysis topics for the second Assessment
The Commission will analyse the impacts of its recommendations in six key areas:
- Public spending impact: The Commission’s binding fiscal remit requires it to demonstrate that all its recommendations are consistent with, and set out how they can be accommodated within, gross public investment in economic infrastructure of between 1.1 and 1.3 per cent of GDP each year between 2025 and 2055.
- Bills impact: the Commission’s reports must also include a transparent assessment of the impact on costs to businesses, consumers, government, public bodies and other end users of infrastructure that would arise from implementing the recommendations. The second Assessment will also show the total costs of recommendations on a household level, comparing current household bills to the additional costs of the Commission’s recommendations.
- Distributional impacts: Assessing whether recommendations will have disproportionate impacts on specific groups of people.
- Climate change impact: Assessing the impacts of economic infrastructure and the Commission’s recommendations on greenhouse gas emissions.
- Environmental impact: Assessing how economic infrastructure and the Commission’s recommendations affect the UK’s natural capital and biodiversity.
- Regional impacts: Assessing whether recommendations will have disproportionate impacts on regions.
