Answered By:

There are in excess of 120 different routes that run through these boroughs and, as such, I have asked TfL to contact you directly with details of vehicles allocated and any plans for further emission enhancements.

TfL's pan-London approach is to bring all vehicles in the bus fleet up to or above the Euro IV engine emission standard for NOx by the end of this year. This will achieve a 20 per cent cut in nitrogen oxides emitted by the fleet compared to 2012 levels.

It is already four-fifths of the way to achieving this goal with more than 1,500 Euro III engine buses retrofitted with selective catalytic reduction (SCR) equipment. SCR achieves NOx reductions of up to 88 per cent in real-world conditions.

The next stage involves retrofitting at least a further 300 Euro III engine buses that are expected to remain on routes for the next few years and replacing others with new ultra-low-emission Euro VI-engine buses which reduce NOx by up to 95 per cent.

This strategy enables TfL to address Euro III buses that are a contributor to NOx emission across the capital in an integrated and cost-efficient way, linked to the tender renewal process. As part of a separate initiative, the current number of 1,400 hybrid diesel electric buses will also increase to more than 1,700 by 2016.
