Analysis: Weaker EV Targets Could Cost UK Consumers £3 Billion a Year by 2030

Weakening UK electric vehicle targets could cost consumers £3 billion a year by 2030, require importing an extra 17 million barrels of oil, and add 2.5% to national emissions, according to Carbon Brief analysis. The analysis comes as the Labour government under Prime Minister Andy Burnham considers cutting the 2030 BEV sales target from 80% to as low as 50%, with a consultation reportedly under review at Number 10.

It could require the UK to import an extra 17m barrels of oil in 2030, raising expected net imports by 8%, as well as adding 2.5% to national emissions that year, the analysis shows. After years of fierce lobbying https://www.carbonbrief.org/factcheck-what-the-uk-car-industry-is-not-saying-about-ev-targets by parts of the car industry — and despite the significant savings https://www.carbonbrief.org/analysis-uks-ev-drivers-are-now-saving-1100-each-a-year-and-3bn-in-total on offer for EV drivers — media reports https://www.carbonbrief.org/daily-briefing-canadas-out-of-control-fires-typhoon-dolphin-deadly-climate-denial suggest that EV targets could be “ watered down https://www.thetimes.com/uk/politics/article/miatta-fahnbulleh-delay-target-fossil-fuels-ffmnr9780 ”. Under current rules, battery EVs — BEVs, those which run only on electricity — must make up a rising share of new car sales in the UK. This policy, known as the “ zero-emission vehicles https://www.carbonbrief.org/factcheck-what-the-uk-car-industry-is-not-saying-about-ev-targets ” ZEV mandate, was introduced https://www.carbonbrief.org/in-depth-qa-what-is-the-uks-net-zero-plan-for-transport by the previous Conservative government and sets a goal for 33% BEV sales in 2026, rising to 80% in 2030. Carmakers are able to use “ flexibilities https://www.carbonbrief.org/factcheck-what-the-uk-car-industry-is-not-saying-about-ev-targets ” to help meet their targets, which reduces the effective target under the ZEV mandate to an estimated https://storage.googleapis.com/public download assets/ecc pdfs/20260505%20ECC%20April%202026.pdf 25% of sales in 2026. Now, the government under new Labour prime minister Andy Burnham https://www.carbonbrief.org/28-quotes-from-next-uk-leader-andy-burnham-on-climate-net-zero-and-fossil-fuels is reported to be considering a cut in the BEV target for 2030 to just 50% https://www.thetimes.com/uk/politics/article/miatta-fahnbulleh-delay-target-fossil-fuels-ffmnr9780 of new car sales, alongside options for 60% or 70%. Carbon Brief understands that a consultation on weakening the ZEV mandate is being reviewed by the prime minister’s office in Number 10, ahead of being formally released. If the mandate is weakened to 50% by 2030 — and if carmakers make more use of “flexibilities” — there could be up to 3m fewer BEVs on UK roads by 2030, according https://www.transportenvironment.org/te-united-kingdom/articles/a-government-flip-flop-on-zev-mandate-would-be-bad-for-drivers-bad-for-the-environment-and-bad-for-british-manufacturing to the NGO T&E https://www.transportenvironment.org/te-united-kingdom/ . Previous Carbon Brief https://www.carbonbrief.org/analysis-uks-ev-drivers-are-now-saving-1100-each-a-year-and-3bn-in-total analysis found that BEVs are around £1,100 cheaper to run per year than a petrol car, thanks to far lower fuel costs. Overall, BEVs are more than £1,000 per year cheaper to own than either petrol cars https://eciu.net/media/press-releases/2025/snap-analysis-evs-still-1-000-cheaper-to-run-with-3p-mile-charge or plug-in hybrids https://eciu.net/media/press-releases/softening-ev-sales-target-could-spark-another-dieselgate-think-tank-says PHEVs, which can run on petrol or electricity . This is according to analysis of the “total cost of ownership” by the Energy and Climate Intelligence Unit https://eciu.net/ ECIU , including purchase price, fuel costs, insurance and proposed pay-per-mile charges https://www.carbonbrief.org/uk-budget-2025-key-climate-and-energy-announcements . In total, Carbon Brief analysis shows that UK drivers could be hit with an extra £3bn in annual ownership costs by 2030, if the ZEV mandate is weakened, as shown below. A weaker ZEV mandate could “put billions of pounds of committed investments at risk”, reports BusinessGreen , including in the EV charging network and battery supply chains. Industry group Energy UK https://www.energy-uk.org.uk/ says https://www.energy-uk.org.uk/publications/energy-uk-explains-why-is-the-zero-emission-vehicle-zev-mandate-important/ that the mandate is “working in the way it was designed to work” and that it is the “single biggest driver of emissions reductions” in government climate plans https://www.carbonbrief.org/qa-the-uk-governments-carbon-budget-delivery-plan-for-2035/ . However, Carbon Brief analysis shows that a weaker ZEV mandate could result in an extra 7.4m tonnes of carbon dioxide emissions MtCO2 in 2030. This would add the equivalent of 2.5% to national emissions in 2030, under the UK’s international climate goal https://www.carbonbrief.org/ccc-cut-uk-emissions-61-by-2030-for-fifth-carbon-budget/ for that year. In addition, a weaker ZEV mandate could result in the UK needing to import an extra 17m barrels of oil in 2030, equivalent to 8% of projected net imports https://www.nstauthority.co.uk/data-and-insights/insights-and-analysis/production-and-expenditure-projections/ that year. Energy UK says that shifting to EVs will help to reduce household energy bills “for everyone”. This is not only through direct cost-of-ownership savings for EV drivers, but also by spreading the costs of upgrading https://www.carbonbrief.org/qa-how-the-uk-government-aims-to-break-link-between-gas-and-electricity-prices the electricity system across a wider user base. Car industry group the Society of Motor Manufacturers and Traders https://www.smmt.co.uk/ claims https://www.smmt.co.uk/ev-mandate-debate-needs-facts-not-anti-industry-fiction/ that its members are spending “billions…on discounts, finance incentives and marketing support” and that “natural” EV demand is below the level required to meet the current ZEV mandate. Its claims are disputed https://www.transportenvironment.org/te-united-kingdom/articles/britains-auto-industrys-case-for-weakening-the-zev-mandate-does-not-stack-up .
