The UK government is considering weakening its near-term zero emission vehicle (ZEV) targets for 2030, with credible reports as of June 2026 indicating that the planned 80% ZEV sales requirement for cars and 70% for vans is under active review.

The current mandate requires 22% of new car sales to be zero emission in 2024, rising to 25% in 2025 and 50% in 2026, on a trajectory toward 80% for cars and 70% for vans by 2030. The 100% target for both categories is fixed at 2035, aligned with the government's decarbonisation commitments under the Climate Change Act. A separate requirement from 2030 onward — that all new cars must be either hybrid or fully zero emission — remains untouched in current discussions.

Pressure to revise these interim targets is mounting from two quarters. Automotive manufacturers have long contended that the ramp, particularly the jump to 50% by 2026, outpaces consumer demand and the rollout of charging infrastructure. What lends political weight to their case is that Unite the union — which represents tens of thousands of workers in UK automotive manufacturing — has now backed a target reduction, supporting revised figures of 38% for cars and 34% for vans in the year following adjustment. Union endorsement of a slowdown removes a key argument the government would normally use to hold firm: that relaxing targets would harm workers, not just the environment.

Under the regulations, manufacturers have some flexibility through a credit and penalty system, but missing annual thresholds carries significant legal exposure. Notably, there are no mandatory CO2 emissions targets for UK manufacturers until the end of 2030, making the ZEV percentage targets the primary compliance mechanism during this period. Revising the 2030 goal would therefore ripple backward through every annual checkpoint, reshaping fleet strategy, capital investment timelines, and inventory decisions across the supply chain.

The 80% and 70% 2030 targets were framed in government documents as "broadly aligned" with earlier technical consultations — they were negotiated figures, not arbitrary ones, reflecting what officials believed technically achievable with sufficient industrial commitment. Revising them now poses a structural risk: if intermediate targets bend under pressure, the market signal to invest in EV manufacturing capacity and charging infrastructure weakens at precisely the moment it should be strongest.

One layer of this picture matters for the broader decarbonisation framework. The 2035 endpoint for 100% ZEV sales has not been flagged for revision, suggesting the government's current thinking is to compress a steeper ramp into fewer years rather than push back the final deadline. This is arithmetically tighter, not looser — but it does delay the mandatory phase-out of combustion engine technology and buys manufacturers time to recover their investment in conventional platforms. Whether that trade-off survives until 2035 will hinge heavily on how quickly the European market, which supplies much of the UK's vehicles, aligns with its own post-2035 combustion phase-out trajectory.

The government's next step — and the precise revised target figures it adopts — will be read closely by manufacturers facing a delicate balance: slash targets too sharply and consumer confidence in the EV transition stalls further; adjust them too modestly and manufacturers may face compliance costs they pass along in pricing, dampening demand from the other side. The Unite endorsement of 38% and 34% interim figures offers ministers a politically defensible resolution. Whether they accept it is now the central question.
