World’s first 24-hour Ultra Low Emission Zone now live in central London


The Mayor of London’s bold action to reduce toxic air pollution and protect Londoners’ health has resulted in the world’s first 24-hour Ultra Low Emission Zone going live in central London today. 

Two million Londoners – including more than 400,000 children – are living in areas which exceed legal limits for air pollution. Thousands of Londoners die early each year because of toxic air pollution. It is stunting the growth of children’s lungs, is a cause of cancer, and increases the risk of asthma, stroke and dementia.

The central London ULEZ will help clean up London’s dangerously polluted air and now operates in the same area as the current Congestion Charging Zone (CCZ). Vehicles that drive in the ULEZ will need to meet tough new emissions standards or pay a daily charge.

It is expected that the introduction of the ULEZ will reduce road transport NOx emissions by around 45 per cent in central London. The Mayor’s wider package of air quality measures, including cleaning up TfL’s buses, no longer licensing diesel taxis, and expanding the ULEZ to inner London in 2021 will cut emissions further. It is expected that this could reduce the number of schools in illegally polluted areas from over 450 down to zero in 2025 and will also help reduce the gap in pollution levels between the most and least deprived areas.

The positive effects of cleaner air will be especially beneficial to the young, older people and those who have respiratory problems, as well as residents of high pollution areas.
