Question to the Department for Transport:

To ask the Secretary of State for Transport, pursuant to the Answer of 18 December 2025 to Question 99840, whether she will publish the full cost-benefit analysis underpinning the Government’s assessment of the Zero Emission Vehicle Mandate, including all assumptions, modelling inputs, sensitivity analyses, and any internal estimates of the proportion of costs falling to the public purse.

A full, final cost-benefit analysis was published alongside the VETS order 2023 on Gov.UK.

A projection of the overall costs falling to government from the policy were not estimated as part of this assessment.
