Research paper concerning the life-cycle CO2 emissions per mile traveled for plug-in hybrid electric vehicles (PHEVs) and battery electric vehicles (BEVs) across the United States. The authors found large variations in the estimates across regions, charging schemes (for example, higher use of coal to generate power during overnight charging), and vehicle models (including differing relative results between models under different regional charging scenarios).

FEV North America, Inc. has been tasked by the US Environmental Protection Agency with conducting an extensive literature review on the subject of EV battery durability to inform the EVE informal group deliberations. This is the second (final) draft version of the FEV study.
