The Scottish government will miss a key target to remove the majority of diesel buses from public transport by next year, according to a report.

Transform Scotland found only about 16% of the bus fleet will be electric or hydrogen powered by the end of 2023.

Its analysis of 10 transport goals stated that while some of the commitments were on track, progress in other areas had slowed or stalled.

Transport Scotland said it was “right to aim high”.

The SNP’s 2021 Holyrood election manifesto pledged to “remove the majority of fossil fuel buses from transport in Scotland by 2023“. The ambition was repeated in ministers’ Programme for Government.
