1. About engine idling

Westminster suffers from the worst air pollution in the country. With 9.9 million drivers in the capital and 370 million miles driven in Westminster each year, road transport contributes to more than half of the most deadly emissions.

We want to take action to improve the air quality for our community and its visitors, by eliminating engine idling from the areas of highest pollution in the city. It’s an issue that affects everyone, so everyone should care. By making this small change we can all make a big difference.



2. Become an air quality champion

We can help reduce the number of idling vehicles by encouraging drivers to minimise or stop idling when stationary through an informative chat, and interactive and engaging resources.

Why not come along and make a difference in our local community? Anti-idling event days are a great way to meet other community members, get to know the area, and improve the air we breathe.

3. Report engine idling

If you see a vehicle engine idling, report it online.

Report engine idling

Leaving an engine running unnecessarily while a vehicle is stationary pollutes the air we breathe, causes unnecessary noise and costs drivers money. Switching off your engine is an easy way to help improve air quality and the health of people in Westminster. 

Turn off your engine when stationary, loading or waiting at the roadside, and:

  • reduce pollution - turning off and restarting an engine causes less pollution than keeping the engine running
  • protect your health - turning off your engine could help to reduce asthma, heart disease and lung cancer
  • save money - idling wastes fuel and money
  • protect your car - idling can increase wear and tear on your engine

Marshals are out on the streets talking to drivers about the impact idling has on pollution, noise and health.

If a driver is asked to turn their engine off by a Marshal and refuses, they could be issued with an £80 Penalty Charge Notice.

4. Spread the word

If you can help us to spread the word about #DontBeIdle and your support of it, we have produced a range of materials to help you do this.

Retail poster

Print and display this poster in your shopfront or office entrance, to remind customers not to idle their engines when parked outside.

Resident poster

5. Businesses

We're calling on businesses in Westminster to help us reduce pollution by switching off engines.
