Summary:
Mayor of London, Sadiq Khan, has announced plans to extend the Ultra Low Emission Zone (ULEZ) to cover all of Greater London. The ULEZ is a pollution charge for vehicles that do not meet European emissions standards and is currently in place in central London. The expansion of the ULEZ is aimed at improving air quality in the city, as 99% of London’s residents live in areas that exceed World Health Organization limits for particulate matter (PM) 2.5, which is largely emitted by vehicles. The ULEZ has had a positive impact on air quality in London, with a 29% reduction in nitrogen dioxide concentrations between July and September 2019, according to the Greater London Authority. However, some research has found that the effects of the ULEZ on air quality are limited due to the proportion of vehicles that already comply and pollution levels linked to other activities and vehicles.
