Summary
A study by Imperial College London estimates that deaths linked to air pollution in London fell by 40% between 2019 and 2024, coinciding with the expansion of the city's ultra-low emission zone (ULEZ). The research found nitrogen dioxide levels dropped 41% and fine particulate pollution fell 28%. London Mayor Sadiq Khan credited the ULEZ policy with saving lives, while Imperial's researchers noted that updated scientific evidence shows air pollution has an even greater impact on health than previously understood.
