When is Clean Air Day in 2025?

Clean Air Day falls on the third Thursday of June every year, so this year's will be on the 19th of June.

ARM Environments are organising a sponsored walk to raise funds for the Ella Roberta Foundation in conjunction with the Building Engineering Services Association (BESA).

The walk will start from the soon to be unveiled memorial for Ella in Mountsfield Park in Catford and end at Elmgreen School in Tulse Hill.

Participants will be citizen scientists for the day, measuring air quality as they take varying routes between the start and finish to see who can avoid air pollution the most.
