Hybrid buses clean up the capital's streets
Hybrid buses, which combine batteries, a conventional diesel engine and an electric motor, are part of the Mayor's plans to improve air quality in the city.
The buses are cleaner, quieter and use around 30 per cent less fuel than a standard diesel bus - lowering operating costs and reducing harmful emissions.
The 300th hybrid bus is now in service on route 211 between Waterloo and Hammersmith.
A further 104 hybrid buses are on order thanks to £5m of funding from the Department for Transport so that, in total, more than 400 will be in service by next year.
In addition, the Mayor has committed to introducing 600 New Bus for London vehicles, which also use hybrid technology.
Combined, this means at least 1,000 hybrid buses will be on the Capital's streets by 2016.
Mayor Boris Johnson said: 'I am determined to clean up London's buses to improve quality of life.
'We are pioneering new technology to do so, including through the wider introduction of these greener hybrid vehicles and my brand new bus for the Capital.
'This is all part of my plans to cut pollution across the city.'
