 The two BEVs modeled, midsize and full-size, are based on the two most popular BEV models sold in the United States in 2015, the Nissan Leaf and the Tesla Model S. The study found that all-electric cars representative of those sold today, on average produce less than half the global warming emissions of comparable gasoline-powered vehicles, despite taken into account the higher emissions associated with BEV manufacturing.Considering the regions where the two most popular electric cars are being sold, excess manufacturing emissions are offset within 6 to 16 months of average driving.The study also concluded that driving an average EV results in lower global warming emissions than driving a gasoline car that gets in regions covering two-thirds of the U.S. population, up from 45% in 2009.
