The Imperial College study now estimates premature deaths attributable to air pollution in London at 6,400–8,000 in 2019, falling to 3,800–5,100 in 2024, a decline of roughly 40%. Nitrogen dioxide levels dropped 41% and fine particulate pollution 28% over the same period. The boroughs with the highest ratio of attributable deaths in 2024 were outer London, including Bexley, Havering and Sutton, after the Ultra Low Emission Zone expanded city-wide in 2023.
