Payback time? As an EV does not remove any CO2 it can never recover the CO2 released in its manufacture, operation or recycling. One does, however, often see comparisons to similar sized ICE vehicles. The two long poles in the tent are the amount of CO2 released in the process of producing the battery and the amount released in operation. The latter clearly depends on where the electricity used to charge comes from. The CO2 released in Quebec (where power comes from hydro) is 0. In West Virginia where power comes from burning coal it is clearly much higher but still only perhaps 20% of that from an ICE vehicle. As estimates of battery carbon burden vary all over the place time to parity also varies all over the place. I've seen estimates of from 2 to 7 years.Anyone want to take a stab at what the carbon payback time is for an EV? I’ve seen some studies, and I recall that the carbon payback is region dependant, and on the order of 5 years.
