Assessments of GHG emissions from light-duty vehicles should take a cradle-to-grave life cycle perspective and capture important regional effects. Lifecycle GHG emissions per km for different powertrain types (ICEV, LW-ICEV HEV, PHEV, and BEV) in selected counties. Darker blue areas show counties with greater emission savings from EVs.
