"More toxic air pollution has been averted by London’s ultra-low emission zones than is produced by the capital’s airports or its river and rail transport combined, according to a new analysis of the effects of the Ulez.
The report showed that improvements in air quality between 2019 and 2022 from lowering motor vehicle pollution – even before the expansion of the Ulez throughout the capital since August – rivalled the potential savings from entirely cleaning up London’s aviation or industrial and commercial heat and power generation."
