On 1 March 2021, tougher standards for the heavy vehicles operating with the Low Emission Zone (LEZ) were introduced. This report shows that six months on from their introduction, these changes were already delivering results. 95 per cent of large and heavy vehicles operating in London met the standards in August 2021, up from 48 per cent in February 2017 when the scheme was announced.
The LEZ also has significant benefits outside of London, with independent analysis showing vehicles that passed through London’s Low Emission Zone went on to drive through 95 per cent of the major towns and cities in England and Wales, bringing air quality benefits to a combined population of 18 million people.
