GLA – First month of Mayor’s ULEZ sees 74 per cent of vehicles comply
Since launching in the central London congestion charging zone on 8 April, the ULEZ has already driven a significant increase in vehicle compliance.
This press release, issued by the Mayor of London, was first published on london.gov.uk
- New figures reveal progress made since February 2017, when the Mayor confirmed the introduction of the Toxicity Charge (T-Charge) as a stepping stone towards the ULEZ
- Number of older, more polluting non-compliant vehicles has reduced by 9,400 on an average day
The Mayor of London, Sadiq Khan, yesterday praised thousands of motorists across the capital for changing their behaviour to help improve London's air quality, as a report evaluating the first month's impact of his Ultra-Low Emission Zone (ULEZ) found that 74 per cent of vehicles driving into the zone were compliant with the new standards.
Polluting vehicles account for around half of London's harmful NOx air emissions, and air pollution costs the capital up to £3.7 billion every year. Launched on 8 April and operating alongside the congestion charge, the world's first Ultra-Low Emission Zone is helping address London's toxic air health crisis that currently leads to thousands of premature deaths annually, and increases the risk of asthma, cancer and dementia.
It operates 24 hours a day, seven days a week, 365 days a year in the central London congestion charging zone. Motorists who drive in the zone in a vehicle that does not meet the new emission standard (petrol vehicles that do not meet Euro 4 standards and diesel vehicles that do not meet Euro 6) have to pay a daily charge.
Yesterday's report examines the initial impact of the ULEZ throughout April, the first month since its launch.* Its key findings include:
- In the first month of operation (excluding non-typical days) the compliance rate with the ULEZ standards was around 74 per cent in a 24-hour period, and 71 per cent in congestion charging hours - a huge increase from 39 per cent in February 2017, and 61 per cent in March 2019 (congestion charging hours).**
- There were around 9,400 fewer older, more polluting, non-compliant vehicles seen in the zone on an average day (excluding non-typical days), a reduction of over a quarter (26 per cent).
In addition to examining the first month after launch, the report also outlines how the 'preparation period' for the ULEZ affected the numbers and types of vehicles driving into central London, as Londoners and businesses replaced their older polluting vehicles and began using cleaner transport alternatives including walking, cycling and public transport.*** The Mayor has also led by example by ensuring every bus operating in central London meets or exceeds the ULEZ standards.
The report highlights how compliance has been improving since February 2017, when the Mayor confirmed the introduction of the Toxicity Charge (T-Charge) as a stepping stone towards the ULEZ and Londoners and businesses began preparing for the new schemes. The report compares the number of vehicles detected in the ULEZ and compliance rates for February 2017, March 2019 (the month before launch) and April 2019, and found that over the period as a whole:
- There were around 36,100 fewer older, more polluting, non-compliant vehicles seen in the zone on an average day (excluding non-typical days), a reduction of around 58 per cent, from February 2017 to April 2019.
- There was an 80 per cent increase in the proportion of vehicles in the central zone that were compliant from February 2017 to April 2019 (excluding non-typical days).
This has already started translating into real-world improvements in air quality, including a reduction of approximately 20 per cent in NO2 concentrations measured at roadside monitoring sites in the zone since February 2017.
