New research shows the carbon emissions benefits of electric vehicles are far greater than initially suspected. Prior studies have shown that manufacturing and driving battery electric vehicles (BEVs) produces substantially less carbon emissions than internal combustion engine vehicles. So for climate-conscious consumers, the case for choosing an electric vehicle over a gasoline vehicle for a new purchase has long been clear. It typically took about three years for the lower emissions of driving a battery electric vehicle to offset the emissions required to produce it. The authors modeled an array of different scenarios for replacing gasoline or standard hybrid electric vehicles with battery electric vehicles before the end of the vehicle’s useful lifespan.
