Welcome to the Heathrow Airwatch website, the source for air quality information in the Heathrow area. This website provides you with information about where air quality is measured around Heathrow and what the air quality levels are right now, and over the past week. There's also more general information about air quality, including an explanation of the terms used.
This site has been funded by a joint working partnership consisting of the Heathrow Airport Ltd, London Boroughs of Hillingdon and Hounslow, Slough and Spelthorne Borough Councils and British Airways. The contact page provides contact information for the Heathrow Airwatch partners.
This website is focused on air quality and does not attempt to address the issues of greenhouse gas emissions and climate change. We recognise that these are serious issues which have links to health related air pollutants, but are beyond the scope of this website. For further information on climate change strategies please contact the relevant project partners.
