Plug-in hybrids spew out 2.5 times more CO2 in real life than in tests

Spewing forth an average of two-and-a-half times the carbon dioxide on the road as they appear to in lab tests, plug-in hybrid vehicles are a 'wolf in sheep's clothing'. This is the warning of groups Greenpeace and Transport & Environment, who argue for hybrids to be added to the upcoming ban on new petrol and diesel cars. Hybrid cars run off of a battery which can be charged either from the electricity grid, or via their conventionally-fuelled onboard engine. While they are often marketed as low-carbon alternatives to traditional vehicles, the groups' analysis suggests that a typical hybrid emits 188.3 grams of CO2 per mile. This is compared with the figure of 70.8 cited from laboratory examinations — a discrepancy that the groups blame on the vehicles' limited range. In addition, they said, hybrid owners do not recharge their vehicles' batteries often enough — increasing their emission levels when driven in reality. UK Transport Secretary Grant Shapps has indicated that a ban on the sales of new petrol, diesel and hybrid vehicles could be brought forward from 2040. The accelerated time frame would help meet carbon reduction targets. 'Plug-in hybrids are the car industry's wolf in sheep's clothing,' said Greenpeace UK's head of politics, Rebecca Newsom. 'They may seem a much more environmentally friendly choice, but false claims of lower emissions are a ploy by car manufacturers to go on producing SUVs and petrol and diesel engines,' she explained. 'It's great that the Government is considering bringing the ban on new ...
