Introduction
For years, the UK car industry has consistently argued that consumer demand for electric vehicles (EVs) is insufficient to meet the government’s ambitious “zero-emission vehicle” (ZEV) targets. However, a closer look at the data reveals a different story: the industry has not only met but exceeded the targets set by the ZEV mandate. This article unpacks the facts behind the rhetoric, exploring how carmakers have leveraged flexibility mechanisms to over-comply, and why the narrative of failure persists.
The Pattern of Pessimism
Each month, the Society of Motor Manufacturers and Traders (SMMT) publishes new UK car sales figures. Following these releases, the SMMT and large segments of the media routinely claim that EV sales are lagging behind the ZEV mandate’s requirements. Dozens of articles have incorrectly stated that car companies are missing their targets, despite official data showing the opposite. This recurring cycle of negative messaging has been used to lobby the government for an “urgent review” of the targets, with the industry arguing that “natural demand is still well below the level demanded by the mandate.”
How the ZEV Mandate Actually Works
Introduced by the Conservative government in 2021 and inspired by California’s similar scheme, the ZEV mandate sets rising annual targets for the share of new car and van sales that must be zero-emission. For cars, the target began at 22% in 2024, increasing gradually to 80% by 2030. Manufacturers that fall short can still avoid penalties by trading credits with other firms or borrowing allowances from future years.
Real Results: Over-Compliance in 2024
In November 2024, the SMMT warned that EV’s market share was “just…18.7%” and that the industry would “likely fall short” of the 22% goal, potentially incurring a £1.8 billion fine. Yet official figures released in early 2025 told a different tale: the car market actually over-complied with the mandate. All carmakers avoided fines, despite EVs accounting for only 19.8% of new sales—a figure higher than the SMMT’s estimate. How? Because the mandate includes a series of flexibilities.
The Role of Flexibilities
These flexibilities, created and expanded after lobbying by the car industry, allow manufacturers to reduce their ZEV sales target by selling internal combustion engine vehicles with lower emissions, such as hybrids or plug-in hybrids. When these adjustments are factored in, the car market met the equivalent of a 24.5% target in 2024—a surplus of 2.5% that could be banked for future years. The government’s data clearly shows this over-compliance, yet the industry’s messaging continues to focus on the headline 22% figure.
Industry Lobbying and Media Amplification
The SMMT’s persistent claims of falling demand have been widely picked up by the media, reinforcing a narrative that the ZEV mandate is unrealistic. However, the data indicates that the industry is using these claims to push for a relaxation of the targets, despite having already proven that compliance is achievable. This pattern of pessimism serves to protect profit margins rather than reflect actual market conditions.
What the Industry Isn’t Saying
Car manufacturers rarely mention the flexibilities that make compliance easier. They also omit the fact that they have banked surplus credits, which will help them meet future, higher targets. By focusing on the unadjusted 22% figure, they create the impression of a struggling market, when in reality, the mandate’s design allows for a smooth transition.
Conclusion
The UK’s ZEV mandate has succeeded in its first year, with the car industry over-complying through available flexibilities. The persistent narrative of failure is not supported by the evidence and appears to be a strategic lobbying tool. As the mandate tightens towards 2030, understanding these mechanisms is crucial for informed policy debate. The industry’s claims should be taken with a grain of salt—especially when the data shows they are already meeting the targets they say are impossible.
