DOE: Life cycle GHG emissions for 2020 electric small SUV were half those of a conventional gasoline small SUV

Green Car Congress

C2G emissions are a sum of WTW emissions and emissions associated with vehicle manufacturing. The vehicle manufacturing cycle includes impacts of raw material extraction, vehicle parts production, assembly, as well as its disposal and related materials recycling processes. Key assumptions for these two scenarios (e.g.,
