Local air pollution

Responsible Heathrow 2020 - Local air pollution

A range of emissions in European and UK cities contribute to local air pollution and we are committed to playing our part in improving air quality in the local area around Heathrow.As well as activities at the airport, local emissions come from surrounding roads, industry and housing.

We are working with partners to reduce emissions from aircraft, vehicles and buildings to make sure we act as a responsible neighbour and play our part in meeting EU and UK Government limits.
