The comments made by Sadiq Khan, the Mayor of London, on 10 December 2021.
This shows how bold action reaps rewards on air quality and climate change. Just one month after expanding the world’s first Ultra Low Emission Zone, we have seen a significant reduction in the number of older, more polluting vehicles driving in our capital. This is vitally important because toxic air is an invisible killer, responsible for one of the biggest public health crises of our generation.
In central London, the ULEZ has already helped cut toxic roadside nitrogen dioxide pollution by nearly half. But pollution isn’t just a central London problem. Everyone should have the right to breathe clean air, which is why expanding the ULEZ was a crucial step. The high compliance rate means that millions of Londoners are already benefiting from cleaner air.
