"Deaths linked to air pollution fell by an estimated 40% in London over the five years from 2019, according to new analysis.
Toxic air pollution in London had reduced sharply, with nitrogen dioxide levels down 41% and fine particulate pollution down 28%.
Imperial’s researchers said updated scientific evidence showed that the impact of air pollution on health was greater than previously understood"
"London is proof that things can be different. Between 2019 and 2024, the city saw a 40% drop in deaths linked to air pollution.
Mayor Sadiq Khan attributed the results to the Ultra Low Emission Zone (Ulez), an area where vehicles that fail to meet minimum emissions standards must pay a daily fee or a fine. Created in 2019, the zone was expanded to include the entire City of London and all of its boroughs in 2023, making it the world’s largest clean air zone. "
"Children’s lungs grew bigger and stronger after the most polluting vehicles were restricted from entering London, a study has found.
The researchers said the findings were a vindication of the low-emission zone policy, which had been criticised as a burden on motorists."
