Scotland is providing funding worth £2 million to make its bus fleet greener.
Transport Minister Humza Yousaf said the latest round of support will see 46 new low emissions buses introduced by three key operators – First Scotland East, Lothian Buses and Stagecoach East Scotland.
The new investment is part of the Scottish Green Bus Fund which has supported 269 low carbon emission buses across the country so far.
Mr Yousaf said: “The Scottish Government is committed to reducing our carbon emissions and one way to do this is by introducing cleaner transport such as these buses.
“The SGBF is also helping our public transport partners invest in the latest emission reducing technology and is another clear indication of our support and commitment to the bus industry in Scotland.”
