Clean Air Day, the UK's largest air pollution campaign

Air pollution is associated with around 30,000 deaths a year in the UK. The World Health Organization and the UK Government recognise that air pollution is the largest environmental threat to our health.

The campaign highlights how both outdoor and indoor pollutants from transport emissions to household products impact our physical, mental, and brain health. It serves as a call to action for individuals, schools, and workplaces to adopt cleaner habits
