London’s Ultra Low Emission Zone cuts NO2 by one-third

London’s Ultra Low Emission Zone (ULEZ) has cut nitrogen dioxide (NO2) pollution by a third since coming into effect on 8 April 2019.

An official report on the ULEZ’s effect on air quality in Central London within the first six months shows it has been successful in cutting pollution. In addition to a significant drop in NO2, the new report shows that there are now 13,500 fewer polluting vehicles being driven into Central London each day.

The report also reveals that the average compliance rate with the ULEZ standards was 77 per cent in a 24-hour period (74 per cent in congestion charging hours). This is significantly higher than the 39 per cent that were compliant in February 2017 and the 61 per cent in March 2019 during congestion charging hours.

Polluting vehicles account for around half of London’s harmful NOx air emissions, with air pollution costing the capital up to £3.7 billion every year.
