True, but the overall carbon reduction in owning an EV over its lifetime is still leagues lower; "Production-weighted average carbon footprints are 183 g CO2e/mi for BEVs; 351 g CO2e/mi for PHEVs; 445 g CO2e/mi for HEVs; and 521 g CO2e/mi for ICEVs." from [0] which does take into account the carbon-emitting percentage of the electrical grid.

Also, see Figure 4[1] in the study which states "Results demonstrate that, even under unfavorable conditions, BEVs still have a 30% lower life cycle carbon footprint."
