Clean Air Day - 17 June 2021

What is Clean Air Day?


We’re proud to be the co-ordinators of the UK’s largest air pollution campaign, Clean Air Day. Since the first Clean Air Day in 2017, thousands of people have taken part in hundreds of events, and our air quality messages have had a reach of millions.


Clean Air Day is an award-winning annual campaign. It works to improve public understanding of air pollution both indoors and outdoors and to build awareness of how air pollution affects our health. The campaign also explains some of the easy things we can all do to tackle air pollution, helping to protect the environment and our health too.

What happens on Clean Air Day?

Clean Air Day is co-ordinated by Global Action Plan, and is made possible by partners who help us fund the day, and supporters who help us deliver it.


It’s a day which brings people together across the UK - from schools, businesses, communities and the health sector. It’s a day of action on air quality where people try something different - this could be anything from choosing to travel without a car, to closing the street in front of your school for a day and having a street party.


Clean Air Day usually takes place on the third Thursday of June, this year taking place on Thursday 17 June 2021.

Over the years, we’ve seen Great Ormond Street close on Clean Air Day to become a rainbow-bedecked play street, people testing their lung capacity in Lung Domes in Manchester’s Piccadilly Gardens and dancing in George Square Glasgow. All around the UK we’ve seen people getting involved in spreading the message that we all have a role to play in making our air clean.
