Title: CO2 emissions associated with electric vehicle charging: The impact of electricity generation mix, charging infrastructure availability and vehicle type

The emission reduction benefits of EVs are dependent on the time and location of charging. An analysis of battery electric and plug-in hybrid vehicles under four charging scenarios and five electricity grid profiles shows that CO2 emissions are highly dependent on the percentage of fossil fuels in the grid mix. Availability of workplace charging generally results in lower emissions, while restricting charging to off-peak hours results in higher total emissions.
