Question to the Department for Transport:

To ask the Secretary of State for Transport, what recent estimate she has made of total transport-sector emissions since July 2024; and if she will make an assessment of how that figures compares with projections made when the Zero Emission Vehicle Mandate was introduced.

Transport was estimated to emit 111.8MtCO2e (megatonnes carbon dioxide equivalent) in 2023, with 78.1MtCO2e from cars and vans. The ZEV Mandate came into force in 2024; it requires that, by 2030, 80% of new cars and 70% of new vans should be fully zero emission. In 2024, the Government estimated that this policy would deliver 420MtCO2e of savings by 2050, averaging a reduction of 5.8MtCO2e between 2028 and 2032 and 15.8MtCO2e between 2033 and 2037. The emission savings estimates have been slightly reduced by the flexibilities announced in April but by less than 3% overall.
