Summary
Clean Air Day is the UK's largest air pollution campaign, engaging thousands of people at hundreds of events, and reaching millions more through the media.

Air pollution is real and harms the health of millions. But there are lots of simple things we can do to improve air quality and look after our own and other people’s health.

Every year, air pollution causes up to 36,000 deaths in the UK.  The World Health Organisation and the UK Government recognise that air pollution is the largest environmental health risk we face today.

Clean Air Day is a chance to find out more about air pollution, share information with friends and colleagues, and help make the air cleaner and healthier for everyone.
