Heathrow Airport: Construction

The question

To ask the Secretary of State for Transport, what assessment her Department has undertaken on the potential impact on air pollution as a result of the expansion of Heathrow.

Answered by Keir Mather

As part of the review of the Airports National Policy Statement (ANPS) the Government will develop updated assessments of the noise and air quality impacts of expansion at Heathrow and will review and update the existing appraisal of sustainability and health impact analysis in line with any amendments made to the ANPS.

We expect to publish any revisions to the ANPS for consultation by summer 2026, together with supporting assessments.
