Fleet Managers Are Losing Confidence in the EV Transition
The road to full fleet electrification was supposed to be clearly signposted. Firm government targets, tightening emissions regulations, and growing corporate sustainability commitments all pointed in the same direction: electric vehicles were the future of company car fleets. But in 2025, that road looks considerably less certain. A growing wave of regulatory ambiguity on both sides of the English Channel is causing fleet operators to pump the brakes on their EV commitments — and in some cases, shift into reverse.
A major new survey from leasing firm Alphabet has laid bare just how significantly the regulatory backdrop is reshaping fleet planning. The findings from Alphabet's 2026 European Fleet Emission Monitor report paint a picture of an industry in genuine strategic confusion, with operators increasingly unwilling to commit to full electrification while the policy ground keeps shifting beneath their feet.
What the Data Actually Shows
The numbers in Alphabet's European Fleet Emission Monitor report are striking. Only half — 50% — of European fleet operators are now factoring sustainability into their fleet planning decisions. That is the lowest figure recorded since the annual study launched in 2023, and it represents a meaningful decline in the corporate appetite for green procurement.
Perhaps even more telling is the reason behind that retreat. A full 60% of respondents cited regulatory uncertainty as a direct factor impacting their decision-making. These are not businesses that have abandoned their environmental credentials out of indifference. Rather, they are pragmatic operators who cannot build a coherent multi-year fleet strategy on a regulatory foundation that keeps changing.
Back in the UK, one in nine businesses — approximately 11% — are now forecasting a permanent long-term role for petrol or diesel vehicles on their company car fleets. That may sound like a minority, but it is a meaningful and growing constituency of operators who have effectively concluded that full electrification is not a realistic near-term destination.
The EU's Softened CO2 Targets Have Changed the Calculus
One of the pivotal moments driving this shift in sentiment was the European Union's decision to soften its CO2 reduction targets for new cars and vans. The original 2021 regulation had set a 100% reduction target by 2035 against a 2021 baseline — effectively an internal combustion engine ban. The revised position weakens that to a 90% reduction, with the remaining 10% compensated through low-carbon steel manufacturing and the use of alternative fuels.
On the surface, a 10 percentage point adjustment may appear modest. In practice, it is a seismic policy shift. It means that hybrid vehicles and conventional combustion-engined cars will remain legally available to sell across European showrooms for longer than previously anticipated. For fleet managers conducting five- to ten-year procurement planning, that changes the entire equation. Why commit fully and immediately to an all-electric fleet if the regulatory endpoint has moved?
The decision reflects political reality across the EU, where several member states pushed back hard against the original timeline, citing consumer affordability concerns and the pace of charging infrastructure rollout. But while the pragmatism is understandable, the consequence for industry planning is a loss of the long-term regulatory certainty that businesses desperately need.
The UK Picture Is No Less Confusing
Although the UK has not directly followed the EU in softening its own 2035 targets — the Zero Emission Vehicle mandate remains in place — the political backdrop for UK fleet decision-makers is far from straightforward. The ZEV mandate requires manufacturers to sell a rising proportion of zero-emission vehicles each year, with escalating penalties for non-compliance. Yet the rules have already been adjusted once, and industry lobbying for further flexibility continues.
For fleet operators, this creates a deeply uncomfortable planning environment. They are being asked to make large-scale procurement decisions — decisions involving significant capital expenditure, multi-year lease agreements, and infrastructure investment — without clear confidence that the regulatory framework underpinning those decisions will remain stable.
Add to this the ongoing variability in benefit-in-kind tax treatment for company cars, uncertainty around public charging infrastructure investment, and the continued evolution of manufacturer EV ranges and pricing, and it becomes easier to understand why fleet managers are hesitant to go all-in on electric.
Hybrids and ICE Vehicles Are Staging a Quiet Comeback
The practical consequence of all this uncertainty is visible in procurement behaviour. Fleet operators are increasingly looking back toward hybrid vehicles — both mild hybrids and plug-in hybrids — as a hedging strategy. These vehicles offer improved emissions performance over traditional combustion engines while avoiding the full infrastructure dependency of pure battery electric vehicles.
Petrol and diesel are also retaining a foothold in fleet planning, particularly for high-mileage drivers, those in rural areas with limited charging access, and operators running specialist or heavy-duty vehicles where EV options remain limited or cost-prohibitive. The return of combustion options to fleet conversations would have seemed unlikely just two years ago. Today, it reflects rational risk management in an uncertain environment.
What Fleet Managers Need to Move Forward
The path back to confident EV adoption is not complicated in principle, even if it is difficult in practice. Fleet operators consistently identify a small number of core requirements:
- Long-term regulatory stability: Businesses need confidence that EV mandates and tax incentive structures will remain consistent over the planning horizon of a typical fleet cycle — typically four to seven years.
- Expanded and reliable public charging infrastructure: Range anxiety remains a genuine barrier for high-mileage fleet drivers, and patchy charging provision continues to undermine confidence in full electrification.
- Transparent total cost of ownership data: Fleet managers need robust, real-world data comparing the whole-life costs of EVs against hybrid and ICE alternatives, including residual values and energy costs.
- Consistent benefit-in-kind tax treatment: The current BIK advantage for zero-emission company cars is a powerful incentive, but fleet planners need assurance it will remain competitive over the medium term.
The Risk of Losing Momentum
There is a broader concern sitting beneath the immediate procurement statistics. The fleet market has historically been one of the most powerful accelerants of new vehicle technology adoption in the UK. Company cars purchased today become used cars available to private buyers in three to four years. If fleet electrification stalls, it slows the flow of affordable second-hand EVs into the wider market — the very vehicles that will be essential for broadening electric adoption beyond early adopters and higher-income buyers.
Regulatory clarity, then, is not just a fleet industry issue. It is a cornerstone of the UK's broader clean transport transition. The current uncertainty is costly — and the longer it persists, the harder and more expensive the eventual catch-up will be.
