Every child in London is breathing toxic air, mainly caused by road vehicles. Led by the Mayor, Sadiq Khan, we are committed to helping Londoners breathe cleaner air.

As part of this commitment, the Ultra Low Emission Zone (ULEZ) in central London operates 24 hours a day.

How to meet air quality standards

If you drive in London, you may have to pay one or more of the charges aimed at improving our air quality. Find out what charges may apply by the type of vehicle you drive, or learn more about each charge.

Drivers going into central London may also have to pay the Congestion Charge.

Air quality consultation

In 2017/18 we consulted on an expansion of the ULEZ. You can see the results on our ULEZ/LEZ consultation page.
