TfL has announced that more than 1,000 older buses on more than 50 of London's routes have now been fitted with equipment that removes around 90% of NOx emissions, concluding the world's biggest emissions busting retrofit scheme.
Innovative pollution reducing equipment has now been installed on the exhaust systems of 1,015 buses operating on more than 50 routes across London, and the Mayor and TfL are now exploring plans to expand the programme further, with the Department for Transport (DfT).
Priority was given to bus routes passing through areas with high nitrogen dioxide concentrations including those serving Elephant and Castle, Marylebone Road, Fulham Broadway, Oxford Street and Putney High Street. The £10m retrofit programme funded by TfL and the DfT has already delivered significant air quality benefits to 102 of the 187 nitrogen dioxide focus areas identified by the Mayor in the capital.
Matthew Pencharz, the Mayor's Senior Advisor for Environment and Energy, said: "Part of the most ambitious and comprehensive programme of measures being driven by the Mayor to reduce emissions and improve London's air quality, this ground-breaking retrofit programme is making a big impact across the city. Greening the capital's bus fleet is one of the Mayor's top priorities. As well as completing the retrofit of over 1,000 older buses with this pollution busting equipment, we continue to expand the city's fleet of hybrid buses - which includes the roll out of the New Routemasters - and are also trialling the use of electricity, hydrogen and bio-diesel to power the capital's fleet."
The retrofit process involves fitting a Selective Catalytic Reduction (SCR) system Such as those commonly found on New Euro VI vehicles, to the exhaust of each bus. The equipment was trialled in 2012, and demonstrated NOx emission reductions of up to 88%.
