The London Atmospheric Emissions Inventory, published by the GLA, includes emissions from airport activity up to 1 km above ground. This feeds into the associated air quality modelling of London and is referenced in my Air Quality Strategy.

The Airports Commission has recently launched its consultation on expansion options at Heathrow and Gatwick. The Commission, in its published technical work, has assumed that the pollution from aircraft is broadly dispersed and so has a limited impact on air quality outside the airport boundary. As a result, the Commission does not seem to have undertaken an assessment of the local air quality impacts of aircraft emissions. I believe this is a serious omission and I will be raising this and other concerns when I submit my response to the Airports Commission consultation.
