London’s most polluting buses are to be upgraded, cutting their emissions by up to 95%.
Mayor of London Sadiq Khan announced around 5,000 buses will take part in the retrofit programme, bringing them up to the latest ultra-low Euro VI emissions standards.
This is around half of the capital city’s existing fleet – by 2020 every London bus will meet the standard.
The £86.1 million programme will see the vehicles fitted with new bespoke exhaust systems to reduce nitrogen oxides and particulate matter.
Currently 700 to 800 low-emission buses are being introduced to the fleet every year as traditional diesel models are slowly phased out.
From next year, all new double-decker buses will be hybrid, electric or hydrogen powered.
The Mayor said: “We know that pollution from our roads is a major contributor to London’s toxic air.
“That’s why we are working so hard to introduce new clean buses on our streets and why we are continually looking for innovative ways to clean up the most polluting buses.”
Earlier this year the Mayor announced the introduction of 10 new Low Emission Bus Zones for the city.
