Some good news for a change! A year on from the ULEZ expansion to outer london, roadside NO2 concentrations are at levels that are up to 4.8% lower than would have been expected without the expansion.
NOx emissions from cars and vans fell by 13% and 16% respectively, while PM2.5 emissions in the area fell by around 31%
Since the original ULEZ was introduced in 2019 compared to a scenario without the ULEZ:
- NOX emissions are estimated to be 24% lower.
- PM2.5 exhaust emissions are estimated to be 29% lower.
- CO2 emissions are estimated to be 2% lower
As of September last year, 96.7% of all vehicles across the whole of London were seen to be ULEZ compliant. 15 months earlier this figure was 91.6%. When the first Low Emission Zone was established, the figure was 39%.
Great news for Londoner's lungs, and a reminder that Public Health interventions are very powerful!
