Question to the Department for Transport:

To ask His Majesty's Government what assessment they have made of whether converting bus routes to trams in urban areas with low-cost vehicles fuelled by biomethane has a role in achieving the UK's commitment to the Global Methane Pledge to reduce methane emissions by 30 per cent by 2030.

Mass transit, including light rail and bus rapid transit, is largely devolved in England outside London. It is for local authorities to determine whether mass transit interventions are appropriate and proportionate, including with respect to technology, fuel choice and local decarbonisation ambitions.
