Question to the Department for Transport:

To ask the Secretary of State for Transport, what estimate he has made of the amount of diesel that is used by the railway network and train companies each year.

The Office Rail and Road produces annual data on rail energy consumption and emissions per financial year since 2005. The latest published data can be found here: https://dataportal.orr.gov.uk/statistics/infrastructure-and-emissions/rail-emissions/table-6105-estimates-of-passenger-and-freight-energy-consumption-and-carbon-dioxide-equivalent-co2e-emissions/.

In our Transport Decarbonisation Plan the government commits to net zero by 2050, with the ambition of removing all diesel only trains by 2040.
