Heathrow Airport: Air Pollution
(asked on 20th July 2017) - View Source
Question to the Department for Transport:
To ask the Secretary of State for Transport, what assessment he has made of the effect of aircraft on air quality levels in the area surrounding Heathrow airport.
This question was answered on 8th September 2017
There are 22 air quality monitoring sites in the area surrounding Heathrow Airport, with monitors measuring a variety of pollutants from all sources. Emissions from aircraft are a ground-level air quality concern when the aircraft are below an altitude of 1000 feet above the ground. Therefore while aircraft do affect air quality levels in the immediate vicinity of the airport, factors other than aircraft have a greater contributory effect.
