Air quality continues to improve in Wandsworth

Air quality is continuing to improve across the borough, with latest data showing pollution levels are down from last year’s.

There has been a significant improvement in levels of the dangerous pollutant, nitrogen dioxide (NO2), which is primarily caused by vehicle engines and commercial and residential fossil fuel heating systems.

The monitoring sites in Clapham Junction, Tooting High Street, Battersea’s Thessaly Road, Putney High Street, and Putney’s Felsham Road all recorded falling pollution levels that meet UK air quality objectives.

In Putney High Street, average concentrations of NO2 recorded in 2024 have fallen by 40 per cent since 2021, while levels have also dropped at each of the other monitoring sites.

Paul White, Cabinet Member for Environment, said: “It’s really encouraging to see the commitment we have made to air quality is making a real difference to levels of pollutants across the borough.

“But we are not complacent about the ongoing hard work needed to continue improving air quality for all our residents and businesses throughout Wandsworth. As part of our latest Air Quality Action Plans, we were one of the first London boroughs to adopt the World Health Organisation’s interim targets and we remain committed to achieving our ambitious local air quality objectives.

“We’ve enhanced our air quality monitoring network and will continue to keep track of pollution levels and take meaningful action to keep improving.”

Wandsworth’s latest air quality monitoring data has been approved by the Mayor of London and the Greater London Authority as part of the London Local Air Quality Management (LLAQM) system.
