London’s red buses turn green

RATP Dev Transit London is one of the largest bus operators in London and is committed to supporting the Mayor of London’s ambitious plans for a zero-emissions bus fleet in the capital by 2034. With 28% of its in-service fleet being fully electric, RATP Dev has the greatest proportion of electric buses in their fleet within the London market.

RATP Dev Transit London began with a pioneering trial of electric buses in 2014, and in 2018 began operating their first two electric routes. Today RATP Dev has 17 electric routes in operation from five converted garages. By the second quarter of 2023 this will increase to 18 electric routes. The five remaining garages are in conceptual planning phase, and RATP Dev Transit London is working towards a fully electric fleet by 2030.

RATP Dev Transit London is highly supportive of ‘green’ transport solutions and is committed to helping to improve the air quality in London for the benefit of all Londoners.
