A further 800 Transport for London (TfL) contracted buses are to be fitted with Selective Catalytic Reduction (SCR) equipment following a £500,000 contribution from the Department for Transport.

It had already been planned to fit a further 400 Euro 3 buses with SCR from October. However, the successful bid for external partnership funding means another 400 will be upgraded in addition to the 1,019 already retrofitted. This cuts individual vehicle exhaust NOx by up to 88%. Other un-retrofitted Euro 3 buses in the fleet will be replaced by Euro 6 buses or better, which cut individual vehicle exhaust NOx by up to 95% compared with a standard Euro 3 vehicle.

The two measures will deliver a 20% cut (equivalent to 1,000 tonnes) of NOx a year from the bus fleet by 2015 compared to 2012 levels.
