Havering Sees Biggest Ulez Air Quality Improvement in London
Several boroughs saw big drops in pollution too. Bromley, Sutton, and Merton all had 15 percent drops. Harrow and Croydon also decreased pollution. London’s mayor expanded the zone last August.
Cars and vans in outer London pollute less. Nitrogen oxide is down 14 percent compared to before the zone expanded. Particle pollution from car exhausts has also dropped, and it is 31 percent lower in outer London now.
Havering has seen pollution fall since 2019 too. Nitrogen oxide dropped 36 percent. To be exempt, petrol cars must be newer, usually registered after 2005. Diesel cars must be newer too, with most needing to be registered after September 2015.
Most outer London cars meet emission rules now. The report found 96.7 percent compliance in September 2024, up from 90.9 percent in June 2023. Non-compliant cars have decreased by 100,000.
Cars failing standards must pay a fee of £12.50 daily to drive inside the zone. London’s mayor backs the emission zone, protecting Londoners’ health. It’s a measure to help children’s lungs, and air quality protects against diseases like asthma. The mayor says expanding the zone was vital.
