Ultra Low Emissions Zone expanded across Greater London in 2023
29 August 2023

The Ultra Low Emissions Zone (ULEZ) has been expanded across Greater London from today (29th August 2023).
The extension moves the ULEZ boundary beyond the existing north and south circular roads, incorporating all London boroughs, from Hayes in the West to Hornchurch in the East, and from Enfield in the North to Biggin Hill in the South.
The new ULEZ is 18 times larger than the current zone and Transport for London (TfL) says it will impact around 160,000 cars and 42,000 vans which currently drive in the new zone on a daily basis, meaning a sizeable 15% of existing traffic flow is liable for the charge.

The expansion promises to improve air quality of more than five million people across the capital, saving an estimated 27,000 tonnes of CO2, reducing nitrogen oxides (NOx) by up to 10%, and reducing PM2.5 emissions by nearly 16%.
