UK ZEV Targets Weakened to 50% by 2030 Could Raise Consumer Energy Costs by £3bn Annually

UK government consultation on easing zero-emission vehicle mandates risks higher energy costs and emissions for households by 2030

The UK government’s consultation on weakening zero-emission vehicle (ZEV) targets to 50% battery electric vehicle sales by 2030—down from current 33% (effective 25% due to carmaker flexibilities)—could raise annual consumer energy costs by up to £3bn by 2030. Weaker targets might also require the UK to import 17 million additional barrels of oil in 2030 and increase national emissions by 2.5% (7.4 million tonnes of CO2). Carbon Brief analysis notes 3 million fewer BEVs on UK roads by 2030 under the proposed targets, though this figure is an estimate with potential for variation.

This friction in energy access directly impacts SUSTENANCE: households would face higher energy costs for transportation and heating as the UK shifts away from cleaner vehicle options. The consultation’s outcome could delay the transition to affordable, low-emission mobility for millions, particularly as carmakers adjust flexibilities and consumer behavior evolves.

Source analysis does not account for post-consultation changes in carmaker incentives or consumer choices. The full detail remains with Carbon Brief’s 2026-08-12 report.
