I’d like to thank the Member for his question and say that the voluntary Welsh bus quality standard, which was published in March of this year, encourages bus operators right across Wales to introduce lower emission vehicles, especially in those areas where the quality of air that we breathe is threatened by harmful emissions where traffic congestion persists. Under that scheme, local authorities are able to prioritise lower emission vehicles under the enhanced requirements of the standards, and if they are achieved, then they can attract a premium payment available from the Welsh Government’s bus services support grant.
