The Mayor of London was speaking a year after the scheme was expanded.
Mayor of London Sadiq Khan stated that the Ulez scheme is not about raising money for Transport for London. He cited the Ulez One Year report, which showed reductions in harmful air pollutants, particularly in boroughs that opposed the expansion. Khan emphasized the scheme's purpose is to improve air quality and noted a significant increase in Ulez-compliant vehicles in London. A City Hall study showed reductions in nitrogen oxides.
