Bus operator Go North East is to introduce its first all-electric services next year.
It is part of a £12m investment in a new fleet of environmentally-friendly vehicles, which includes nine electric and 34 low-emission busses (pictured).
Most of the new buses will start operating in September in Newcastle, Sunderland and Durham, with electric vehicles due to be on the road by July 2020.
MD Martijn Gilbert said: “If we are serious about improving air quality then we have to properly embrace public transport and tackle rising congestion.
"These buses represent a major investment from us as we continue to play our part in supporting the mass mobility and connectivity of the communities we serve by providing high quality, dependable and green public transport services."
