Today I have received figures on the new bus for London's fuel economy and emissions from Transport for London (TfL).
The Routemaster-inspired bus, which runs on diesel and electricity, has been touted by the mayor as "the greenest double decker hybrid in the world", and is being used to argue for more investment in London transport.
Today the mayor is in Northern Ireland showing off the new chassis production line for the 'New Bus for London', a modern design based on the old Routemaster which has prototypes running on two routes.
