Conclusion
5th Report - Airport expansion and clim…
Deferred
We heard concerns that if airport expansion is focused around the South East of England it could concentrate wider growth in those regions. This could be detrimental to the aviation and airport sectors, and the local economy, around the rest of the United Kingdom. Whilst there were representations from regional …
Government response. The government's response deflects by discussing the review of air quality limits and other environmental assessments for Heathrow expansion, with consultations in summer 2026, without addressing the committee's concern about the regional concentration of economic growth.
4
Recommendation
5th Report - Airport expansion and clim…
Accepted in Part
In response to this report the Government should set out how the planned expansion of London Airports will impact the aviation and airport sector around the rest of the UK and the economic impact and level of growth in the wider regions. We recommend that this analysis should be published …
Government response. The government stated that the DfT will develop updated analysis on the economic impacts of Heathrow expansion as part of the ANPS review and will consider changes to the Making Best Use policy for airports beyond Heathrow.
5
Conclusion
5th Report - Airport expansion and clim…
Deferred
The Government has confirmed that it is updating the Airports National Policy Statement (ANPS). We welcome the letter from the then Aviation Minister, Mike Kane MP, to the Committee following his appearance which confirmed that the Heathrow decision would not be taken before the new ANPS is published. (Conclusion, Paragraph …
Government response. The government's response deflects from the committee's welcome of the ANPS update and Heathrow decision delay, instead detailing the review of noise impacts for Heathrow expansion, with mitigations and consultations planned for summer 2026.
6
Conclusion
5th Report - Airport expansion and clim…
Deferred
We are concerned that airport expansion plans will have been produced prior to the publication of a new ANPS which ought to be in place to provide the airports with strategic guidance. We are also deeply concerned that, given a number of airport expansions will have been approved prior to …
Government response. The government deflects from the concern about airport expansion plans being approved under an outdated policy framework by stating that it is reviewing and updating environmental assessments like the Appraisal of Sustainability and Habitats Regulations Assessment, which will be subject …

Conclusion
5th Report - Airport expansion and clim…
Acknowledged
Whilst air pollution around Heathrow has reduced in recent years due to cleaner aircraft and road vehicles, airport expansion will make it harder for Governments, both national and local, to deliver on air quality targets. The Airports National Policy Statement fails to sufficiently account for the impact airport expansion will …
Government response. The government stated that as part of the ANPS review, DfT is considering how air quality tests for Heathrow expansion should be set, reviewing changes in legislation/policy/data, and determining mitigations for air quality impacts, with consultation in summer 2026.
9
Recommendation
5th Report - Airport expansion and clim…
Deferred
The Government, when updating the Airports National Policy Statement, should impose air quality limits for areas surrounding airports covering all key air quality pollutants such as nitrogen oxides and particulate matter. Having established those limits, government should require that any airport expansion is accompanied by measures to ensure no consequential …
Government response. The government deflects the recommendation for air quality limits and pollution mitigation around airports by detailing its Non-CO2 Research and Development Programme and Contrails Impact Mitigation Task and Finish Group, focusing on non-CO2 climate impacts rather than local air quality.
10
Recommendation
5th Report - Airport expansion and clim…
Deferred
The Government should set out in its response to this report what work and research it is supporting to reduce non-CO2 emissions that damage air quality around airports. It should also confirm whether it has identified which current aircraft have the least impact on air quality around airports. We recommend …
Government response. The government deflects the recommendation regarding non-CO2 emissions and local air quality around airports by focusing its response on carbon pricing mechanisms (UK ETS, CORSIA), decarbonisation targets, sustainable aviation fuels, and global action for achieving net-zero CO2 emissions by 2050.
11
Conclusion
5th Report - Airport expansion and clim…
Deferred
The Airports National Policy Statement fails to account for noise pollution. Whilst improvements have been seen in reducing the level of noise made by individual flights, more must be done to minimise the impact on those who live under and around flight paths. (Conclusion, Paragraph 58)
Government response. The government stated its policy to mitigate aviation noise and noted that the DfT is considering noise impacts and mitigations as part of an ongoing Airports National Policy Statement (ANPS) review, with any amendments subject to consultation in summer 2026.
12
Recommendation
5th Report - Airport expansion and clim…
Deferred
The Government should ensure that it is actively working to minimise and mitigate all impacts of noise pollution on relevant populations caused through flying. It should also include a target, within the new ANPS, on the level of acceptable noise from flights both individually and cumulatively. The Government should set …
Government response. The government entirely deflects the recommendation on noise pollution mitigation and setting noise targets in the ANPS by discussing its use of carbon markets (UK ETS, CORSIA) to drive CO2 decarbonisation in the aviation sector.
13
Conclusion
5th Report - Airport expansion and clim…
Acknowledged
We understand the need for the Government to modernise the airspace around the UK, particularly if this will minimise the queuing of planes at airports and reduce the time planes spend circling before they can land. However, this work is likely to expand the area covered by flight paths and …
Government response. The government details its ANPS review for Heathrow expansion, stating that its four tests, including climate, air quality, and noise, will be considered. It commits to consultations on any ANPS amendments and associated environmental assessments by summer 2026, and to …
14
Recommendation
5th Report - Airport expansion and clim…
Deferred
The Government must publish an impact assessment of its airspace modernisation work in regard to how it will change noise impacts as well as publish a map which allows people to see where the noise of aircraft is likely to exceed the World Health Organisation (WHO) recommended levels. Where this …
Government response. The government defers to an ongoing ANPS review which will consider relevant changes and be subject to consultation by summer 2026. Specific impact assessments, maps, and mitigation expansion will be part of future DCO applications, rather than being committed to …
15
Recommendation
5th Report - Airport expansion and clim…
Accepted
The Airports National Policy Statement (ANPS) is not fit for purpose and requires updating to reflect Government policy. The ANPS specifically fails to: • Provide an integrated view on the role of the aviation and airport system across the country as a whole, • Provide information on environmental limits including …
Government response. The government confirmed that a review of the ANPS commenced in October and will consider legislative changes, environmental tests (including cumulative impacts), and update associated assessments, with DfT expecting to consult on a revised ANPS by July 2026 if amendments …
16
Recommendation
5th Report - Airport expansion and clim…
Deferred
The Government should update the Airports National Policy Statement no later than six months after the publication of this report. The updated Statement should: • set out a coherent plan from Government about the airport and aviation system that takes into account wider innovations such as flight path modernisation and …
Government response. The government has begun a review of the ANPS and expects to consult on a revised ANPS by July 2026 if amendments are needed, significantly deferring the committee's recommended six-month timeline.
17
Conclusion
5th Report - Airport expansion and clim…
Accepted
Whilst the Committee understands the Government position that it includes international aviation emissions within its carbon calculations, the UK is yet to formally legislate to include international aviation emissions within the Carbon Budgets, despite it agreeing to do so previously. (Conclusion, Paragraph 79) 45
Government response. The government accepted the committee's observation, stating it is already acting on the basis that international aviation emissions are formally included from 2033 and intends to lay the relevant legislation by summer 2026.
18
Recommendation
5th Report - Airport expansion and clim…
Accepted
We reiterate the recommendation made by the Climate Change Committee, our predecessor Committee and others that the Government makes Parliamentary time available to introduce the necessary legislation to formally include international aviation emissions within Carbon Budgets and its Net Zero targets. The Government should do this within the current Parliamentary …
Government response. The government accepts the recommendation, stating they intend to lay the necessary legislation to formally include international aviation emissions within Carbon Budgets by summer 2026, subject to parliamentary time.
19
Conclusion
5th Report - Airport expansion and clim…
Accepted
Whilst a reduction in aviation emissions is necessary to deliver a net zero aviation sector, an important contribution to the UK’s efforts is the reduction of non-CO2 effects, such as contrails. (Conclusion, Paragraph 81)
Government response. The government acknowledges the importance of addressing non-CO2 aviation impacts like contrails, highlighting existing initiatives such as the £29 million Non-CO2 Research and Development Programme and the Contrails Impact Mitigation Task and Finish Group.
20
Recommendation
5th Report - Airport expansion and clim…
Deferred
Within six months of the publication of this report the Government must consult on airspace-wide contrail avoidance measures. Furthermore, given the significant role that non-CO2 effects play in global warming, the Government must account for these in its assessment of the overall impact of the aviation sector. (Recommendation, Paragraph 82)
Government response. The government acknowledges the recommendation but defers action on contrail avoidance consultation and accounting for non-CO2 effects due to significant uncertainty and ongoing research. It highlights a £29m R&D programme and a task group assessing feasibility, with findings to inform …
21
Conclusion
5th Report - Airport expansion and clim…
Acknowledged
The Government’s Jet Zero Strategy remains reliant on demand management measures that are as yet insufficient to deliver Net Zero objectives, especially if there is an increase in demand. The strategy relies on a far higher cost to industry to abate carbon emissions than are currently seen. It also requires …
Government response. The government acknowledges the committee's concerns about the Jet Zero Strategy, clarifying that carbon prices and emission savings were illustrative, and reaffirms its commitment to strengthening the UK ETS and developing Sustainable Aviation Fuels as key parts of its existing …
22
Recommendation
5th Report - Airport expansion and clim…
Acknowledged
The government’s Jet Zero strategy is now a few years old and was commissioned under the previous government. Government should consider updating the analysis of the baseline and the pathways to net zero aviation. It should ensure that the plans have kept pace with technological developments in the time since …
Government response. The government reiterated its commitment to carbon pricing and strengthening the UK ETS and CORSIA, clarifying that the Jet Zero Strategy's carbon prices and emission savings were illustrative, not targets. It mentioned a recent monitoring and evaluation report to inform …
23
Recommendation
5th Report - Airport expansion and clim…
Not Addressed
If the Government proceeds with airport expansion it should set out to the Committee in its response to this report, in-depth analysis on: • How it will ensure carbon costs will reach the level the Government expected in the Jet Zero Strategy. It should also set out a realistic timeline …
Government response. The government reiterated its commitment to existing carbon pricing mechanisms and stated that Jet Zero Strategy figures were illustrative, not targets. It did not provide the requested in-depth analysis on how carbon costs would be ensured, specific emission savings, penalties, …
24
Conclusion
5th Report - Airport expansion and clim…
Accepted
The aviation sector does not fully pay for its carbon emissions, whether this is through the lack of a direct carbon tax, VAT on its fuel, or the greater benefits it receives through the Emissions Trading Scheme compared to other high emitting sectors. This makes aviation artificially cheap and provides …
Government response. The government stated that it drives decarbonisation through existing carbon pricing schemes like the UK ETS and CORSIA, which align with the ‘polluter pays’ principle, and committed to reviewing the treatment of Sustainable Aviation Fuel under the UK ETS.
25
Recommendation
5th Report - Airport expansion and clim…
Accepted
The Government should ensure that the aviation sector pays its fair share towards mitigating its carbon emissions and the benefits it receives in comparison to other sectors. Aviation should be included in Emissions Trading Schemes and the government should include the use of Sustainable Aviation Fuels within the ETS. (Recommendation, …
Government response. The government states that aviation is already included in the UK Emissions Trading Scheme for certain flights, and the scheme already supports the use of Sustainable Aviation Fuels. It notes the UK ETS Authority will review SAF treatment and consult …
26
Recommendation
5th Report - Airport expansion and clim…
Accepted
Government should also conduct a wider review of aviation taxation to ensure that the ‘polluter pays’ principle is upheld, and the aviation industry does not receive benefits which are denied to other important industries. The aviation industry will then be incentivised to decrease emissions. (Recommendation, Paragraph 113)
Government response. The government stated that Air Passenger Duty and carbon markets like the UK ETS and CORSIA already incorporate the ‘polluter pays’ principle and drive decarbonisation, without committing to a wider review of aviation taxation.
27
Conclusion
5th Report - Airport expansion and clim…
Acknowledged
Whilst it may be possible for the Government to deliver airport expansion alongside its climate and environment targets, we are concerned that the proposed environmental impact from airport expansion will make such targets significantly more difficult to achieve and at much greater effort and cost. Furthermore, the Government has not …
Government response. The government reaffirmed its commitment to net zero, stating that airport expansion is factored into carbon planning and that the ANPS review will consider climate, air quality, and noise, alongside reviewing and updating various environmental assessments. It also committed to …
28
Recommendation
5th Report - Airport expansion and clim…
Accepted
The Government must undertake a detailed review on whether significant airport expansion will realistically allow it to deliver on its legally binding climate, environment and biodiversity targets. This should include a detailed examination of the measures that need to be taken to remain within the aviation carbon budget. (Recommendation, Paragraph …
Government response. The government accepts the recommendation, stating that a review of the Airports National Policy Statement (ANPS) commenced in October to consider changes in legislation, policy, and data. This review will assess compliance with climate and environmental commitments, update assessments, and …
29
Recommendation
5th Report - Airport expansion and clim…
Accepted
The results of this review should be published before or alongside the refreshed ANPS and before any further substantial airport expansion projects are underway. This is crucial to enable proper scrutiny. Failure to do so could put the Government and any airport expansion projects at risk of legal challenge which …
Government response. The government committed that any amendments to the ANPS and its associated assessments, reflecting the review's findings, will be subject to consultation by summer 2026 as part of the parliamentary scrutiny process.
