The UK government is undertaking a review of its flagship zero emission vehicle (ZEV) mandate, a policy designed to accelerate the transition to electric vehicles, following a sharp decline in domestic car production. With UK vehicle production hitting its lowest level since 1952, ministers are now considering adjustments to the quotas carmakers must meet for EV sales. The move raises questions about the future pace of the UK’s ambitious climate goals and the broader strategy for decarbonizing transport.
The ZEV mandate, introduced by the Labour government after taking power in 2024, requires manufacturers to ensure an increasing percentage of their fresh car and van sales are zero-emission each year. The ultimate aim is to effectively ban the sale of new petrol and diesel cars by 2030, with a full 100% target set for 2035. The targets increase annually, with 22% required in 2024, 28% in 2025, and 33% slated for 2026. Non-compliance carries significant financial penalties for automakers.
Production Decline and Policy Review
The review comes as new figures reveal a significant downturn in UK car manufacturing. February 2026 saw a 17% drop in overall vehicle production compared to the same period in 2025, according to recent data. Production of electric, plug-in hybrid, and hybrid vehicles also experienced a decline, falling by 3% to 26,629 units. This downturn has prompted concerns within the industry and fueled calls for a reassessment of the ZEV mandate’s current trajectory.
A government spokesperson confirmed the review, stating, “We recognise manufacturers are facing challenges, but we’ve shown we are adaptable before, and are beginning conversations to inform the planned review of the ZEV mandate, to be published by early 2027.” They added that, despite the challenges, “It has never been easier or cheaper to own an EV, especially against the backdrop of high and fluctuating prices at the pumps,” and pointed to government grants aimed at boosting EV sales.
Industry Concerns and Political Reactions
The ZEV mandate has faced criticism from some quarters, with concerns raised about its potential impact on carmakers’ profitability and the affordability of electric vehicles for consumers. The Society of Motor Manufacturers and Traders (SMMT) has highlighted the financial burden placed on manufacturers by the mandate, estimating that penalties for non-compliance have already cost the industry around £10 billion over the first two years. These costs have, in turn, led to discounts on EVs to encourage sales.
The Conservative party has been vocal in its opposition to the mandate, accusing the government of pursuing “misguided net zero zealotry.” Richard Holden, the Tory shadow transport secretary, argued that the Conservatives have a more pragmatic plan, “led by innovation and consumer choice rather than an ideological direction set by [Net Zero Secretary] Ed Miliband.” He urged the government to adopt the Conservative’s alternative approach.
Labour, however, remains committed to its ambitious targets. The party aims to increase domestic vehicle manufacturing to 1.3 million vehicles per year by 2035 – nearly double the current output. This ambition underscores the government’s belief that a thriving EV industry is crucial for both environmental sustainability and economic growth.
Factors Influencing the EV Market
Several factors are contributing to the current challenges in the EV market. In April 2025, the government removed some buyer incentives, including the vehicle excise duty exemption for EVs, and announced plans for a “pay-per-mile” road tax for electric vehicles starting in 2028. These changes have potentially dampened consumer demand.
international trade dynamics are playing a role. The imposition of 25% import tariffs on cars and car parts from the US by former President Donald Trump has impacted the UK market, given the significant trade relationship between the two countries and with the EU. In response, the government adjusted the ZEV mandate slightly, allowing hybrids to remain on sale until 2035 and exempting smaller manufacturers from the 2030 phase-out of petrol and diesel vehicles. Carmakers were also given more flexibility in how they meet the ZEV targets.
What’s Next?
The outcome of the government’s review, expected to be published by early 2027, will be crucial in shaping the future of the UK’s electric vehicle market. The review will likely consider the pace of EV adoption, the availability of charging infrastructure, and the competitiveness of the UK automotive industry. Stakeholders will be closely watching for any adjustments to the ZEV mandate, which could have significant implications for both car manufacturers, and consumers. The government has indicated a willingness to adapt, but the extent of any changes remains to be seen.
The ongoing debate highlights the complex challenges of transitioning to a low-carbon economy. Balancing environmental ambitions with economic realities will be key to ensuring a sustainable and equitable future for the UK automotive industry.
