Question to the Department for Transport:

To ask the Secretary of State for Transport, whether his Department has made an assessment of the potential merits of offering incentives for the adoption of fuel converters that lower the total amount of emissions produced by a vehicle.

The Department has not investigated the merits of offering incentives for fuel converters. Companies who have developed retrofit technologies are encouraged to utilise the Government’s Clean Vehicle Retrofit Accreditation Scheme (CVRAS). This scheme has been designed specifically to allow them to have their performance assessed and verified independently.
