Question to the Department for Transport:

To ask the Secretary of State for Transport, what assessment her Department has made of the potential impact of a third runway at Heathrow Airport on the likelihood of annual nitrogen dioxide emissions in the Greater London urban area exceeding the 2025 level.

To inform the draft Heathrow Expansion National Policy Statement, the department commissioned indicative analysis, more detail on this analysis can be found here: Air quality support for review of ANPS: review of emissions source data and trends (NO2, NOX, PM10 and ammonia) and here: Air Quality Support for Review of ANPS: Review of Airside Emissions.
