There are 3,826 hybrid buses, 1,397 battery electric buses, and 20 hydrogen fuel cell buses operating in London, as of March 2024, out of a total bus fleet of 8,776 – this is around 60% of the bus fleet.[1]
As of March 2024[update], the battery electric fleet of the city is the second largest in Europe behind of Moscow, which has over 1,700 electric buses operating.[2] Transport for London (TfL) note that the bus fleet has the lowest carbon dioxide emissions per passenger kilometre of other major cities such as New York, Paris and Vancouver.[3]
In 2021, it was announced that all buses in the fleet meet or exceed Euro VI emission standards, following the phasing out of older buses, the retrofitting of diesel vehicles and the introduction of new hybrid & electric buses.[4] From 2021, all new buses will be zero emission, and the entire bus fleet will be zero emission by 2034,[5][6] although TfL have stated that with additional funding, this could be achieved by 2030.[4][7]

The number of zero emission vehicles in the fleet is expected to increase to 700 by the end of 2021.
