We collaborate with funders and supporter organisations on our Clean Air Day campaign to raise awareness and increase public understanding of the health impacts of air pollution and how we can take collective action for cleaner air.

Since 2017, Clean Air Day has:

  • Engaged businesses, schools, hospitals, health professionals, local authorities and devolved governments to take action on air pollution
  • Promoted walking, cycling and active travel to schools all over the country
  • Supported streets across the country to close as play streets, including Great Ormond Street enabling some children who had not been able to go outside for many months to come out and play
  • Resulted in the first petition to be handed in to the Labour government in July 2024, calling on them to get on board with clean air.

"Air pollution is the biggest environmental threat to your health, no matter who you are or where you live. It can harm every organ in your body, causing heart and lung disease, dementia, and strokes. But the good news is that the solutions to our air pollution problem already exist."
