Under the existing ZEV mandate, car manufacturers operating in the UK are legally bound to ensure a rising percentage of the new vehicles they sell each year are zero-emission. This trajectory was designed to accelerate the transition away from fossil fuel cars, starting at 22% for 2024, increasing to 33% by 2026, and ultimately aiming for 80% of all new car sales to be fully electric by 2030. The government’s new proposal, however, suggests a potential cut to this critical 2030 target, contemplating a reduction to as low as 50% of all new car sales by the end of the decade. This consultation period is expected to conclude in late October, allowing various stakeholders to present their arguments.
This potential policy shift has ignited a fervent debate among industry players, environmental advocates, and political figures. Environmental groups have swiftly condemned the proposed relaxation, arguing that watering down such a crucial target would severely undermine the UK’s long-term climate commitments and its international standing on decarbonisation. They contend that any dilution of the mandate sends a dangerous signal, suggesting a wavering resolve in the face of the escalating climate crisis.
The implications of reducing the 2030 target from 80% to 50% are substantial. Primarily, it would provide car makers with greater flexibility to sell a higher proportion of hybrid vehicles, rather than pure battery electric vehicles (BEVs), to meet their overall sales obligations. If the pure electric sales target were indeed dropped to 50%, the remaining 50% could then comprise hybrid models, which combine a traditional internal combustion engine with an electric motor. While hybrids offer better fuel efficiency and lower emissions than purely petrol or diesel cars, they are not zero-emission and still contribute to air pollution and carbon footprints. This scenario contrasts sharply with the original intent of the ZEV mandate, which prioritised the rapid adoption of pure electric vehicles.
Another option being considered in the review is maintaining the 80% target for 2030 but introducing extended flexibility for car makers, potentially allowing them until as late as 2034 to fully comply. This approach aims to ease the immediate pressure on manufacturers while theoretically keeping the long-term ambition intact. Regardless of the specific outcome of the consultation, the overarching policy of an outright ban on selling new purely petrol or diesel cars beyond 2030 is set to remain in place. Similarly, a longer-term deadline for phasing out the sale of new hybrid vehicles by 2035 is also expected to be upheld, suggesting a continued, albeit potentially slower, transition towards a fully electric fleet.
The journey towards phasing out fossil fuel vehicles in the UK has been marked by several policy shifts. Boris Johnson, during his premiership, initially announced a ban on new petrol and diesel vehicle sales by 2030. However, his successor, Rishi Sunak, later pushed this deadline back to 2035, while simultaneously introducing the more gradual targets enshrined within the ZEV mandate. Labour, currently in opposition, has been quick to criticise these historical changes, accusing previous Conservative governments of "moving goalposts on phase out dates," a sentiment that could gain further traction if the current targets are indeed softened.
The primary catalyst for this review comes directly from the motor industry, which has persistently urged ministers to ease the targets. Industry figures argue that consumer demand for electric vehicles has not yet reached a sufficient level to meet the ambitious mandated growth, and that the financial burden of complying with the current ZEV mandate is proving too costly for manufacturers. This pressure comes despite data from the Society of Motor Manufacturers and Traders (SMMT) indicating that electric cars already accounted for a quarter of total new car sales in the UK during the first seven months of the year. While a significant proportion, manufacturers contend that the mandated year-on-year increases are becoming increasingly challenging without stronger market pull.
Mike Hawes, the influential boss of the SMMT, the leading car industry lobby group, stated that the ZEV mandate was "conceived under vastly different conditions." This implicitly refers to a period prior to recent economic headwinds, supply chain disruptions, and the cost of living crisis, all of which have impacted consumer purchasing power and confidence in making large investments like new EVs. He welcomed the review as a "timely opportunity to adjust the transition so it works for all," highlighting the industry’s desire for a more pragmatic and achievable pathway. Lisa Brankin, managing director of Ford of Britain, echoed this sentiment, welcoming the government’s "willingness to listen" to car makers and emphasising the vital need for "certainty" for both the industry and customers to plan long-term investments.
On the government’s side, Transport Secretary Heidi Alexander defended the review, stating on Friday: "It’s right we keep targets under review to ensure they’re practical and back British industry." She clarified that "The end goal hasn’t changed – but we need to take business with us on the journey, and that’s exactly what we’re doing today, by making sure industry has the chance to shape how we get there." This statement underscores a perceived need to balance environmental ambition with economic realism and industrial support, suggesting that a rapid transition without industry buy-in could jeopardise the sector.
However, electric car advocates and climate groups have vehemently criticised the government’s proposed flexibility. Tanya Sinclair, the boss of industry group Electric Vehicles UK, expressed dismay at the timing, questioning why the government would be "asking whether we should extend the availability of polluting vehicles amid our hottest summer on record." This highlights the perceived urgency of climate action and the disconnect between policy review and immediate environmental challenges.
Further solidifying these concerns, the Energy & Climate Intelligence Unit (ECIU), a respected think tank, conducted an analysis estimating that cutting the EV sales target to 50% by 2030 would result in a staggering 2.6 million fewer electric cars on UK roads by 2035. Such a reduction in EV uptake would inevitably lead to higher cumulative emissions, undermining the UK’s climate objectives. Gurjeet Grewal, chief of Octopus Electric Vehicles, warned that weakening the mandate "would send exactly the wrong signal, just as EVs are becoming some of the best-value cars on the road." He argued that softening targets could erode consumer confidence, slow down investment in crucial charging infrastructure, and ultimately delay the benefits of EVs, such as lower running costs, which have become particularly attractive given the spikes in petrol prices, exacerbated by global events like the Iran war.
The Climate Change Committee (CCC), which serves as the government’s independent adviser on climate change, has consistently identified the switch from diesel and petrol engines to EVs as the single most effective way of cutting carbon emissions over the next decade. Their expert advice stands in stark contrast to any policy that might decelerate this transition. The Green Alliance, another influential environmental think tank, warned that watering down targets would "lock in avoidable emissions while undermining the certainty manufacturers need to invest." This argument counters the industry’s call for certainty by asserting that clear, ambitious long-term targets are what truly provide manufacturers with the confidence to invest heavily in electric vehicle production and supply chains, rather than delaying the inevitable transition.
The debate also touches upon the role of hybrid vehicles. While often seen as a transitional technology, critics argue that an over-reliance on hybrids, particularly plug-in hybrids (PHEVs), could prolong the use of fossil fuels and delay the necessary investment in pure EV infrastructure. PHEVs, despite their electric range, still rely on internal combustion engines for longer journeys and can be charged infrequently if drivers do not fully utilise their electric capabilities.
Internationally, the UK’s potential backtracking could also send mixed signals. Many major economies, including those within the European Union and the United States, are pushing ahead with their own ambitious electrification strategies. A perceived weakening of resolve in the UK might impact foreign investment in its automotive sector, which is increasingly focused on EV manufacturing.
In essence, the government’s review of the ZEV mandate is a high-stakes balancing act. It seeks to reconcile the automotive industry’s pleas for a more gradual, less financially burdensome transition with the urgent demands of climate action and the long-term benefits of a fully electrified transport system. The outcome of this consultation will not only shape the future of the UK car market but also serve as a crucial test of the nation’s commitment to its environmental promises.
