We agree with the European Commission's conclusion that legislation on car efficiency is necessary. The target should be challenging but achievable. A target for average new car tailpipe CO2 emissions of 130 g/km is, in principle, around the right level. But more work will be necessary to examine the feasibility and impacts of this target (including full impact assessments and consultation) before making any final decisions. Similarly, there will need to be careful consideration of how the target should be structured. We will continue to engage actively in discussions at the EU level, and we will also be calling on the European Commission to develop longer term targets in order to give the car industry greater certainty.
