Taking both production and expected lifetime into account, the answer is 'maybe, especially if coal is used to power both'.

"The study highlights in particular the "toxicity" of the electric car's manufacturing process compared to conventional petrol/diesel cars. It concludes that the "global warming potential" of the process used to make electric cars is twice that of conventional cars.

The study also says - as has been noted many times before - that electric cars do not make sense if the electricity they consume is produced predominately by coal-fired power stations."


"Although EVs are an important technological breakthrough with substantial potential environmental benefits, these cannot be harnessed everywhere and in every condition."
