The researchers found that in Europe, electric cars pose a "10% to 24% decrease in global warming potential (GWP) ".

The researchers suggest to improve eco-friendliness of electric vehicles by "reducing vehicle production supply chain impacts and promoting clean electricity sources " and using the electric cars for a longer time, .
