Energy: In many countries, hybrid gas/EVs emit lower emissions than pure electric vehicles

An average battery electric and plug-in hybrid electric cars using electricity characterised by the current global average carbon intensity (518 grammes of carbon-dioxide equivalent per kilowatt-hour [g CO2-eq/kWh]) emit less GHGs than a global average ICE vehicle using gasoline over their life cycle. But the extent ultimately depends on the power mix: CO2 emissions savings are significantly higher for electric cars used in countries where the power generation mix is dominated by low-carbon sources. In countries where the power generation mix is dominated by coal, hybrid vehicles exhibit lower emissions than EVs.
