Green buses and coaches made up 53.5% of all new buses registered in the UK in 2015.
That’s a threefold increase compared to 2014, according to data released by the Society of Motor Manufacturers and Traders (SMMT).
The models registered had low emission Euro-VI technology, which captures 99% of soot particulates and “drastically” reduces emissions of Nitrogen Oxides (NOx).
The boost in demand for this type of vehicle comes as the regulatory period of grace which has allowed operators to specify older technologies for their fleets is due to end, the SMMT added.
Operators in Glasgow and Birmingham renewed the largest proportion of their fleets with 143 new Euro-VI vehicles.
In London more than a half of new vehicles featured the green technology.

Mike Hawes, SMMT Chief Executive said: “Industry has invested billions of pounds in advanced vehicle technology that delivers real results so it is encouraging to see this rapid uptake of Euro-VI in the UK.
“The UK automotive sector remains committed to working alongside operators, government and local councils to encourage widespread adoption of the latest vehicles that will help dramatically improve the air quality in our towns and cities.”
