The capital's most polluting buses are set to undergo a clean-up in an £86m programme, London mayor Sadiq Khan announced today.
Over half of London's bus fleet will upgraded to meet the latest Euro 6 emissions standard, so around 5,000 buses will be given a new exhaust system to slash emissions.
Transport for London's managing director of surface transport, Leon Daniels, said installing the green engine tech will mean being "able to reduce vehicle exhaust emissions significantly" – by up to 95 per cent.
By September 2020, the capital's entire bus fleet will meet the Euro 6 emissions standard at least.
The mayor had already previously announced that hundreds of new low-emission buses are being introduced to the fleet, and diesel-only buses are being phased out. From next year, all new double-deck buses will be either hybrid, electric or hydrogen.
In November, the mayor unveiled London's first hydrogen double-decker bus, and these are being trialled on the capital's roads this year. In March, Putney High Street was named the first of London's low-emission bus zones, serviced by cleaner buses to clamp down on nitrogen oxide emissions.
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.
There’s no doubt that by cutting the emissions of more than half of the fleet by up to 95 per cent, this innovative retrofit programme is going to make a huge difference to Londoners.
Some 11 other low-emission bus zones are planned by 2020, including Uxbridge Road to Shepherds Bush, Edmonton to Seven Sisters, and Lewisham to Catford.
