New analysis by Kearney, a consultancy, suggests the car industry is on course to run out of its remaining “carbon budget” by 2035, and that it will overshoot by as much as 75% by 2050. However, many experts believe the industry is far from achieving emissions reductions that would be compatible with less than 1.5C of global heating, the goal of the 2015 Paris climate agreement. Lawmakers should treat PHEVs based on their actual emissions.”Ĭutting the car industry’s carbon emissions is seen as a vital part of slowing the rate of global heating. In city tests, just one of the PHEVs has the electric range advertised, while all three emit more than claimed in commuter driving. But real-world testing shows this is a myth. Some in the industry expect a minimum zero-emissions range requirement for cars to be allowed to be sold.Īnna Krajinska, vehicle emissions manager at T&E, said: “Plug-in hybrids are sold as the perfect combination of a battery for all your local needs and an engine for long distances. The findings come as the UK government considers which hybrids will be allowed for sale between 2030 and the complete ban on new hybrid sales in 2035. T&E said the tests showed governments should focus on incentivising the purchase of fully electric vehicles rather than hybrids. The Peugeot 308 managed just over half the electric range, while the BMW 3 Series achieved three-quarters. The Peugeot and the BMW also failed to live up to their official zero-emissions range. The latest data suggest that PHEV technology in some newer models still pollutes significantly more than official tests suggest. The campaign group Transport & Environment (T&E) commissioned the Graz researchers after similar analysis in 2020 found much higher emissions than advertised from PHEVs, particularly as some users do not charge them. Burning more fuel adds to running costs and increases polluting carbon emissions. Tests by independent groups, including UK consumer group Which?, have repeatedly found that PHEVs burn more fuel than the laboratory figures suggest. Peugeot’s 308 polluted 20% more than its official rating of 27g, while Renault’s Megane was 70% above the official test of 30g. The research found that BMW’s 3 Series emitted 112g of carbon dioxide per kilometre, three times its official rating of 36g. However, campaigners argue that the cars are more polluting than claimed. Carmakers say they can offer the best of both worlds by allowing owners to drive long distances while retaining the ability to drive with zero emissions. Plug-in hybrid electric vehicles (PHEVs) combine a small battery with a traditional petrol or diesel engine.
