In London, the implementation and expansion of the Ultra-Low Emission Zone (ULEZ) has reduced air pollution by decreasing amounts of nitrogen dioxide, fine particulate matter and carbon emissions, according to new data by City Hall reviewed by independent air quality experts.
In total, air quality in London is improving at a faster rate compared to the rest of England, and the ULEZ has reduced enough carbon emissions to equal the impact of removing 3 million one-way passenger trips from Heathrow Airport to New York City, according to the report.
The Ultra-Low Emission Zone was first implemented in 2019, when it became the first low-emission zone to operate 24/7. In February 2023, a peer-reviewed study by the London mayor’s office showed that the zone was working after an initial expansion to include inner London. At that point, the zone had led to a 21% decrease in nitrogen dioxide levels in inner London and a 46% reduction in these emissions in central London. That report also found a decline in fine particulate matter and carbon emissions both inside the ULEZ and across London entirely.
In August 2023, the ULEZ was expanded again to cover the entire city, with expectations that this move would improve air quality for 5 million more people living in London’s outer boroughs. The ULEZ is now the largest low-emission zone globally.
Now, new data proves that London's ultra-low emission zone has made serious improvements to the air quality in and around the city, including a 27% decline in nitrogen dioxide levels, across London.
“When I was first elected, evidence showed it would take 193 years to bring London’s air pollution within legal limits if the current efforts continued. However, due to our transformative policies we are now close to achieving it this year,” London Mayor Sadiq Khan said in a statement. “Today’s report shows that ULEZ works, driving down levels of pollution, taking old polluting cars off our roads and bringing cleaner air to millions more Londoners.”
