Recommendation 21

There are a range of other issues that will need to be considered as part of the transition to zero-emission cars. We are concerned about the impact of lost taxes from fuel duty and the potential standstill in technological change for the internal combustion engine.48 The Department for Transport explained that technological changes for the internal combustion engine are not expected to stop as it is using regulatory instruments to continue to drive down carbon emissions in these engines, including for other vehicles like buses. The Department expects to publish a Green Paper on the post-EU regime for carbon emissions later in 2021.49
