Letter to Secretary of State for Transport relating to the Government response to the committees report on Airport expansion and Climate and Nature targets, 22 January 2026

From: Environmental Audit Committee

Inquiry: Airport expansion and climate and nature targets

Summary

The Environmental Audit Committee welcomes the Government's general response to its airport expansion report but expresses significant concerns about lack of specificity. The committee seeks clarification on economic analysis, air quality limits, noise targets, carbon budgeting mechanisms, sustainable aviation fuel analysis, and parliamentary scrutiny arrangements for the revised Airports National Policy Statement, requesting a response by 28 February 2026.

Key findings

  • Committee welcomes government commitment to use ANPS review to address Net Zero, pollution, and biodiversity issues, and commitment to include international aviation emissions in carbon budgets from 2033 onwards by summer 2026
  • Committee remains concerned response lacks specific targets, measures, and explicit commitments needed to scrutinise progress on balancing airport expansion with climate and environmental goals
  • Committee requests confirmation that government will provide detailed economic impact data for airports beyond Heathrow, including cumulative effects on regional airports
  • Committee seeks explicit air quality pollution ceilings, noise targets benchmarked against WHO limits, and transparent mapping of noise pollution exceedances in revised ANPS
  • Committee expresses concern that parliamentary time commitment for aviation carbon budget legislation carries qualification 'subject to parliamentary time availability'—language used previously without legislative follow-through
