New Mayor for London Sadiq Khan has announced that he plans to more than double the size of the proposed new Ultra Low Emissions Zone so that it covers the area ringed by the North and South Circular roads.
Previously Boris Johnson had proposed that the zone would only cover the Congestion Charge area.
With the new boundaries the ULEZ will cover much of Lambeth including Vauxhall, Stockwell and Brixton which have high levels of air pollution.
The extension of the ULEZ will also bring benefits to areas of Lambeth such as Streatham, Norwood and Gypsy Hill which are outside the zone. These areas are served by bus routes that travel into the zone and these will run using ULEZ compliant cleaner buses. It is estimated that over half the pollution in densly packed roads such as Streatham High Road and in central Brixton over half of the pollution comes from buses. These measures will come into place, subject to consultation, in 2020.
