Answered By:

In my earlier answer to MQ 1381/2013, it was not stated that TfL would be testing emissions of vehicles on route 24 as computer monitoring systems on buses do not measure exhaust emissions. This can be most effectively achieved at an official test facility which enables all buses to be compared in identical operating conditions. This has already been undertaken for a New Routemaster and demonstrated that it offers much better fuel consumption compared to similar generation double-deck buses.

TfL has committed to publishing comparative fuel consumption data on New Routemasters in service as soon as it is finalised.
