Clean Air Night 2025 - Celebration and insights report

(14/10/25)
Report cover: Clean Air Night 2025. Celebration and insights report. The background of the cover is a dark sky scattered in stars.

Wood burning is one of the biggest sources of the air pollution in the UK, contributing to a range of health problems including lung and heart disease, diabetes and dementia. But many people are not aware of the facts about wood burning – or may have been exposed to confusing messages about burning. We believe that everyone should have access to the information they need to make informed decisions about how to heat their homes.

The second year of Clean Air Night focused on sparking more productive conversations about these health harms of wood burning, focusing much of our campaigning on London – where the vast majority of people have another way to heat their home and the health impacts of burning can be felt by many people. It was amazing to see people across London and the country learning about this burning issue and sharing what they had learned online and with friends and family.

Here are some highlights from the second Clean Air Night campaign:

  • 65% campaign awareness ion London, with 992,370 Londoners reached with information about the health harms of wood burning through paid media.

  • 116 media mentions of Clean Air Night, including coverage in The Times, Daily Express, LBC, Yahoo, BBC Radio 5 Live and the Daily Record.

  • 92% of people in the UK who are aware of Clean Air Night support the introduction of at least one measure to tackle air pollution from wood burning in their local area.
