"The global warming potential from electric vehicle production is about twice that of conventional vehicles."
In addition, producing batteries and electric motors requires a lot of toxic minerals such as nickel, copper and aluminium. Hence, the acidification impact is much greater than that of conventional car production.
In regions where fossil fuels are the main sources of power, electric cars offer no benefits and may even cause more harm, the report said.
"It is counterproductive to promote electric vehicles in regions where electricity is primarily produced from lignite, coal or even heavy oil combustion."
