A new analysis estimates that deaths linked to London’s air pollution fall by around 40% over the five years from 2019. The study is led by researchers at Imperial College London and examines health outcomes associated with pollution levels in the capital. According to the reporting, the researchers also find that air pollution has a worse impact on health than previously understood, suggesting earlier estimates may have underestimated harm.
The findings are being presented in the context of London’s Ultra Low Emission Zone (ULEZ). Mayor Sadiq Khan publicly welcomes the results and describes them as strong evidence that the ULEZ is helping prevent deaths. Multiple outlets cite the mayor’s position that the study provides compelling support for the policy’s expansion.
Some coverage also notes related efforts to improve air quality beyond ULEZ, including initiatives and funding for cleaner-air projects in London boroughs, as well as broader public information about the ongoing push to reduce pollution. The reports overall treat the figures as estimates from the Imperial College analysis, rather than directly measured individual outcomes.
