ICCT: PHEVs electrify many trips, but currently emit on average 2-4 times more CO2 than advertised
Plug-in hybrid electric vehicles (PHEVs), which combine an electric and a conventional combustion engine drive train, offer the potential to reduce global greenhouse gas (GHG) emissions and local air pollution if they drive mainly on electricity. However, there is limited evidence on how much driving PHEVs actually do on electricity and how much conventional fuel they use in real-world operation.
