Deaths linked to London air pollution have fallen 40%, study estimates
Summary
A study from Imperial College London found that deaths linked to air pollution in London dropped by about 40% between 2019 and 2024. The study also showed large cuts in harmful air pollutants and linked improvements to the city’s ultra-low emission zone (Ulez), which charges older, more polluting vehicles to reduce pollution.Key Facts
- Deaths tied to air pollution in London fell by an estimated 40% from 2019 to 2024.
- Nitrogen dioxide pollution dropped by 41%, and fine particulate matter fell by 28%. These are harmful substances that affect health.
- The number of premature deaths caused by air pollution was revised up to between 6,400 and 8,000 in 2019, falling to between 3,800 and 5,100 in 2024.
- London’s Ulez charges vehicles that do not meet emission standards to reduce pollution; most vehicles in the zone now meet these standards.
- Boroughs farther from central London still have the highest pollution-linked deaths, highlighting the need to expand Ulez city-wide.
- Other efforts include funding indoor air filters for schools and increasing zero emission buses in London’s public transport.
- Experts say clear action on pollution leads to real health benefits, but some groups call for further measures as many children still suffer breathing problems.
