Question to the Department for Transport:

To ask the Secretary of State for Transport, what assessment his Department has made of the potential effect of a third runway at Heathrow Airport on (a) noise and (b) air quality in West London.

The Appraisal of Sustainability that accompanies the revised draft Airports National Policy Statement provides a strategic level assessment of the potential social, economic, and environmental impacts of expansion, including on noise and air quality.

Should the revised draft Airports National Policy Statement be designated, then it would be for the promoter to undertake a detailed assessment of the noise and air quality impacts of the scheme, and put forward an appropriate package of mitigation measures.
