The government's response
Published 12 January 2026. The deadline was 24 December 2025.
Summary written by Accountability Index from the government's response. It is not the government's own words.The Government's response largely points to its ongoing review of the Airports National Policy Statement (ANPS), with any proposed amendments to be consulted on in summer 2026, while setting out its existing carbon pricing and sustainable aviation fuel measures.
- On economic analysis, the Department for Transport (DfT) will develop updated analysis of the economic impacts of Heathrow expansion, with outputs published alongside any ANPS amendments for consultation "by summer 2026".
- On air quality and noise, the Government says mitigations "will be determined as part of the review process", with any amendments to the existing ANPS subject to consultation in summer 2026.
- On including international aviation emissions in carbon budgets, the Government says that, "subject to the allowances of parliamentary time", it "intends to lay the relevant legislation by summer 2026".
- On the Committee's request for a six-month contrail consultation and accounting for non-CO2 effects, the Government points to significant uncertainty about non-CO2 impacts and its research programme, with contrail findings to be published "in due course".

Recommendations and conclusions 29 shown
2: Commission detailed research and set out expected economic growth from airport expansion.
Recommended (the committee's words)3: Government failed to address concerns over regional economic impact of South East airport expansion.
Concluded (the committee's words)4: Publish analysis of London airport expansion's economic impact on wider UK regions.

Concluded (the committee's words)7: Current airport planning approach lacks strategic UK-wide consideration and scrutiny.
Recommended (the committee's words)8: Airport expansion hinders air quality targets; ANPS fails to account for pollution impact.
Concluded (the committee's words)9: Impose air quality limits around airports and mandate measures for no net pollution increase.
Recommended (the committee's words)10: Incentivise airlines to use aircraft reducing non-CO2 emissions and consult on fleet age
Recommended (the committee's words)11: Airports National Policy Statement inadequate in accounting for aircraft noise pollution
Concluded (the committee's words)12: Include specific noise pollution targets for flights within updated Airports National Policy Statement
Recommended (the committee's words)13: Airspace modernisation likely to expand flight paths and increase noise impact
Concluded (the committee's words)14: Publish noise and biodiversity impact assessments for airspace modernisation, and expand mitigation
Recommended (the committee's words)15: Airports National Policy Statement unfit for purpose, lacking integrated environmental limits
Recommended (the committee's words)16: Update Airports National Policy Statement with coherent plan, specific environmental limits, and cumulative impacts
Recommended (the committee's words)17: International aviation emissions not formally legislated within UK Carbon Budgets
Concluded (the committee's words)18: Legislate to formally include international aviation emissions within Carbon Budgets and Net Zero targets
Recommended (the committee's words)19: Reducing non-CO2 aviation effects like contrails crucial for achieving net zero
Concluded (the committee's words)20: Require consultation on airspace-wide contrail avoidance and account for non-CO2 aviation effects.
Recommended (the committee's words)21: Government's Jet Zero Strategy insufficient to deliver Net Zero aviation objectives.
Concluded (the committee's words)22: Update Jet Zero Strategy analysis to reflect technological developments and current policy changes.
Recommended (the committee's words)23: Set out detailed analysis on aviation impacts and mitigations if airport expansion proceeds.
Recommended (the committee's words)24: Aviation sector's carbon emissions are not fully paid for, creating artificial cheapness.
Concluded (the committee's words)25: Ensure aviation sector pays fair share and include Sustainable Aviation Fuels in ETS.
Recommended (the committee's words)26: Conduct wider review of aviation taxation to ensure 'polluter pays' principle is upheld.
Recommended (the committee's words)27: Airport expansion risks climate targets and lacks demonstrated economic benefits outweighing environmental harm.
Concluded (the committee's words)28: Undertake detailed review of airport expansion's impact on climate, environment, and biodiversity targets.
Recommended (the committee's words)29: Publish detailed review findings on airport expansion before refreshed ANPS or new projects.
