Khan says he is fighting a "war on poisonous air" as City Hall launches ULEZ expansion consultation

Expanding the Ultra-Low Emission Zone to cover the whole of Greater London could take more than 100,000 older, more polluting cars off the road, according to Sadiq Khan.The Mayor of London on Friday invited Londoners to have their say on his plans to further expand the ULEZ from August 2023 in a bid to cut toxic air pollution and congestion in the capital.Under the plans, drivers of vehicles which do not meet strict emissions standards would face a daily charge of £12.50 to drive within the M25 boundary. The zone currently stretches from the north to the south circular road following an initial expansion last October.
