EV Targets in the UK: Separating Industry Claims from Reality
In recent years, the UK car industry has repeatedly argued that consumer demand for electric vehicles (EVs) is too weak to meet government-mandated sales targets. However, official data tells a different story: manufacturers have actually beaten these targets thanks to flexible compliance rules. This Q&A unpacks the facts behind the headlines, explaining how the ZEV mandate works, what the industry is not saying, and why an ‘urgent review’ may be unnecessary.
Why does the UK car industry claim EV demand is too low?
Every month, after the Society of Motor Manufacturers and Traders (SMMT) publishes new UK car sales figures, the industry warns that natural demand for electric vehicles is falling short of the government’s Zero Emission Vehicle (ZEV) mandate targets. For example, in November 2024, the SMMT stated that EV market share stood at just 18.7% and that the industry was ‘likely to fall short’ of the 22% target, potentially incurring £1.8 billion in compliance costs. These claims are then widely amplified by media outlets, which often incorrectly report that car companies are missing their targets. The industry uses this narrative to lobby for an ‘urgent review’ of the mandate, arguing that the mandated levels are out of step with real-world demand. However, as we’ll see, this framing ignores the flexibilities built into the system that allow manufacturers to over-comply even when raw EV sales appear lower.
Has the car industry actually missed its ZEV targets?
No, the industry as a whole has not missed its targets. In fact, official figures published in early 2026 confirmed that the UK car market ‘over-complied’ with the ZEV mandate in 2024. Although only 19.8% of new car sales were pure battery electric vehicles (BEVs) that year—lower than the headline 22% target—the mandate includes a range of flexibilities. When these are taken into account, the industry met the equivalent of a 24.5% target, banking a surplus of 2.5% credits for future years. Every carmaker avoided fines. The key point is that the 22% figure is not a hard, unadjusted requirement; it is reduced by credits earned from selling low-emission combustion cars, hybrids, and plug-in hybrids. So while the industry’s public messaging focuses on the raw BEV share, the reality is that compliance was achieved comfortably.
How does the UK’s ZEV mandate actually work?
Introduced by the Conservative government in 2021 and inspired by California’s scheme, the ZEV mandate sets rising annual targets for the share of new car and van sales that must be zero-emission vehicles. For cars, the target started at 22% in 2024 and increases gradually to 80% by 2030. Each manufacturer must meet its individual target, calculated based on total sales. If they fall short, they can either buy ‘credits’ from other companies that have exceeded their targets, or ‘borrow’ allowances from future years. Importantly, the mandate also includes flexibilities: selling combustion-engine cars with lower CO2 emissions—such as hybrids or plug-in hybrids—can reduce a manufacturer’s effective ZEV target. This means the headline 22% is not the actual bar; the real required share is lower, depending on each firm’s product mix. The government calculates compliance after applying these flexibilities, which explains how the industry over-complied in 2024.
What are the flexibilities and how did they help in 2024?
The ZEV mandate’s flexibilities are mechanisms that allow manufacturers to lower their effective zero-emission sales target. They were created and expanded after lobbying by the car industry itself. The main flexibility lets firms count sales of low-emission combustion-engine cars—like mild hybrids, full hybrids, and plug-in hybrids—as reducing the ZEV target proportionally. For example, a company selling many efficient hybrids might see its required EV share drop from 22% to, say, 18% or 19%. In 2024, when raw BEV sales were 19.8%, the application of these flexibilities meant the market’s actual compliance threshold was equivalent to a 24.5% target. The surplus of 2.5% was ‘banked’ as credits for future years. Without these flexibilities, the industry would have missed the 22% mark, but since they exist—and were heavily negotiated by manufacturers—the industry’s claim of missing targets is misleading. Essentially, the system works as intended, giving firms headroom while still pushing for higher EV adoption.
What was the actual compliance outcome for 2024?
Official government data published in early 2026 show that the UK car market over-complied with the ZEV mandate in 2024. After applying all flexibilities, the industry met the equivalent of a 24.5% target, beating the headline 22% by 2.5 percentage points. This surplus was ‘banked’ to be used in future years. No manufacturer paid any fines. The final raw EV market share was 19.8%, slightly higher than the industry’s November 2024 estimate of 18.7%, but still below the unadjusted 22%. The over-compliance was possible because many manufacturers sold enough low-emission hybrids and plug-in hybrids to lower their effective targets. This outcome contradicts the industry’s narrative of a demand crisis. It also shows that the mandate’s design—with its built-in flexibilities—provides a realistic pathway for the transition, even if public adoption of pure EVs is slower than hoped.
Why does the industry want an ‘urgent review’ of the targets?
Despite over-complying in 2024, the car industry continues to lobby for an ‘urgent review’ of the ZEV mandate. The SMMT and other groups argue that ‘natural demand is still well below the level demanded by the mandate’ and that the rising targets (e.g., 28% in 2025, 33% in 2026) will become unattainable without stronger consumer incentives. Critics suggest the real motive is to slow down the transition timeline and reduce production costs, as many manufacturers are struggling to sell EVs profitably. However, the fact that the industry met the 2024 target with ease—thanks to flexibilities they themselves requested—undermines the urgency of their request. The government has so far resisted a full review, maintaining that the mandate is working as intended. The industry’s focus on raw BEV share rather than compliance metrics appears to be a strategic move to shape public and policy perception, potentially aiming for weaker future targets or more generous flexibilities.
