ULEZ Success? London's Air Quality Improves, Deaths Drop by 40%!
A new study reveals a significant 40% reduction in air pollution-related deaths in London since 2019. Is ULEZ the game-changer? Dive into the details and Sadiq Khan's reaction!
London Mayor Sadiq Khan has declared the expansion of the Ultra Low Emission Zone (ULEZ) to be "crucial," following a groundbreaking new study. This report estimates a significant 40 percent reduction in deaths linked to toxic air across the capital over the past five years.
The ULEZ, which now stands as the world's largest pollution charging zone, began its expansion across inner London in October 2021. Its reach was further broadened to encompass the entire city in August 2023. Under the scheme, vehicles failing to meet minimum emissions standards, and without specific exemptions, are required to pay a daily fee of £12.50 for entering the zone.
A recent report by Imperial College London's environmental research group highlights a dramatic improvement. The study estimates that the number of premature deaths in London attributable to poor air quality was between 3,800 and 5,100 in 2024, a notable decrease from 6,400 to 8,000 in 2019. The authors of the study, which was commissioned by the Greater London Authority and Transport for London, noted that they used "a scientifically stronger approach" compared to previous research.
Researchers also found a substantial drop in fine particulate pollution – extremely small particles that can have serious health implications – falling by 28% from 2019 to 2024. While the report does not isolate the impact of ULEZ as a standalone policy, or any other single measure, Mayor Khan attributes the positive changes to the city's "bold action."
Boosting air quality has been a key priority for Sir Sadiq since he took office in 2016. In addition to introducing the ULEZ in April 2019, other related measures contributing to London's cleaner air include a scrappage scheme for older, more polluting vehicles, providing air quality filters in schools, and increasing the number of electric buses. Sir Sadiq stated, "The evidence is now overwhelming and unarguable: the bold action we have taken in London has reduced pollution, improved public health and saved lives. From childhood asthma to dementia, we know what a wide range of [impacts toxic air has]."
