Just two weeks after the launch of the Ultra Low Emission Zone (ULEZ) in central London, the Mayor and TfL have taken further measures to reduce toxic air in the capital’s most polluted areas by introducing three new Low Emission Bus Zones (LEBZ). The three zones, in Lewisham, Stratford and Edmonton, cover more than 1,330 buses across 79 different bus routes.

Only buses that meet the cleanest emission standards operate within the new LEBZs, which have been delivered through a combination of new and retrofitted vehicles. This takes the total number of clean buses introduced as a result of the LEBZ to more than 3,000. The Mayor has pledged to work towards the entire London bus fleet being made up of zero emission vehicles.

In working towards this goal TfL has committed to ensuring the entire bus fleet uses the cleanest Euro VI vehicles as a minimum and has already upgraded more than three quarters of its buses to meet or exceed this standard, with all buses due to meet this standard by October 2020. This will mean that next year the entire city will become a Low Emission Bus Zone.

Cleanest in the world

London’s bus fleet is already one of the cleanest in the world with all buses operating in central London meeting or exceeding tough new ULEZ admissions standards. Under Sadiq’s leadership, London now has Europe’s largest zero emission bus fleet, with 68 new electric double deck buses to be in place by summer 2019. TfL is only buying zero emission or hybrid double deck buses, as well as retrofitting older buses to reduce NOx emissions by up to 90%. In addition, all new single deck buses will be zero emission from 2020. The entire fleet of around 9,000 buses will be zero emission by 2037 at the latest. There are now ten LEBZs across London, reducing NOx emissions from buses by up to 90% along some of the capital’s most polluted roads. In the Putney High Street LEBZ hourly exceedances of nitrogen dioxide (NO2) have been reduced by up to 99% and annual concentrations by nearly 50%.

In Brixton the LEBZ reduced hourly exceedances of NO2 by up to 85% and annual concentrations by nearly 20%. With the completion of these three new zones, TfL will reduce toxic air pollution for more than 40 schools, nurseries and academies along the routes and surrounding roads. The Mayor of London, Sadiq Khan, said: ‘London is facing an air quality emergency, with pollution from vehicles, including buses, responsible for over half the harmful emissions we breathe.

‘Our existing Low Emission Bus Zones have dramatically reduced pollution and improved the health of thousands of Londoners who live or work along the routes – I’m delighted we can now bring the benefits to Lewisham, Stratford and Edmonton.

‘These zones complement the introduction of the world’s first Ultra Low Emission Zone in central London earlier this month.

‘Experts estimate that without action it would take 193 years to bring London’s air quality to within legal levels – but with the action we’re taking we can hope to achieve this goal in just six years.’
