About the project

Vehicle Idling Action is a London-wide behaviour change campaign which is helping to reduce localised air pollution caused by motorists leaving their engines running when parked.

The project has expanded to 31 local authorities. We are continuing the delivery of idling action events, in which teams of volunteers, local authority officers and project staff work to educate both motorists and pedestrians. We are also delivering school workshops, engaging with businesses, offering vehicle fleet training, and are working with all local authorities to ensure idling regulations are enforced across London.

The project to date

The Idling Action Project has been running since 2016. Now in its fourth phase it is jointly led by the City of London Corporation and the London Borough of Camden. The campaign is funded by the Mayor’s Air Quality Fund.
