What is the carbon footprint of electric cars?

All vehicles emit greenhouse gas (GHG) emissions at one or more life stages during manufacturing, operation, and end-of-life and the amounts differ significantly between gas-powered cars and electric cars. During the manufacturing phase electric vehicles usually emit more GHG emissions than gas vehicles however this reverses shortly after the cars hit the road. At about 6 months, gas vehicle GHG emissions surpass electric vehicle GHG emissions, and from then on electric vehicle GHG emissions are significantly lower. 

Electric vehicles do not have tailpipes and do not directly produce GHGs. However the source of electricity powering the vehicle matters. Washington State, with a predominantly renewable and clean electricity grid, is one of the best states in the country to reduce GHG emissions by transitioning to electric transportation.
