. . . The team from Carnegie Mellon University led by Dr. Jeremy Michalek accounted for regional differences in emissions due to marginal grid mix; ambient temperature; patterns of vehicle miles traveled (VMT); and driving conditions (city versus highway). . . .

As usual, for the ICE it only takes in to account the burning of that gallon of fuel in the ice, not drilling for it, pumping it out, moving it, refining it, pumping it again, delivered via another ICE to a gas station, then pumping it finally in to your vehicle. I wish I could remember where I read it, but if I recall correctly, to get a gallon of gasoline to the average car in the use consumes over 1 kWh of electricity, right there alone throws everything out the window...

If they want to compare them, then include everything, don't pick and choose depending on the vehicle on the road.

Drives me nuts...

They then derived estimated life cycle CO2 emissions for each vehicle type and location by adding vehicle and battery manufacturing emissions, gasoline combustion and upstream emissions (based on computed gasoline consumption), and electricity production and upstream emissions (based on computed electricity consumption, timing, and location).
