It’s what engineers and anyone who can do the math have been telling folks for years:

Data shows PHEVs emit just 19% less CO2 than petrol and diesel cars, an analysis by the non-profit advocacy group Transport and Environment found on Thursday. Under laboratory tests, they were assumed to be 75% less polluting.

When they look closely (and correctly) at Battery powered cars, they are gonna find that they aren’t as “green” as people think either.
