Ultra Low Emission Zone
London UK vehicle charging zone
The Ultra Low Emission Zone (ULEZ) is an area in London, England, where an emissions standard based charge is applied to non-compliant road vehicles. Plans were announced by London Mayor Boris Johnson in March 2015 for the zone to come into operation in September 2020. Sadiq Khan, the subsequent mayor, introduced the zone early on 8 April 2019. The zone initially covered Central London, the same area as the existing London congestion charge and raised £224 million in 2022.
