Researchers find Nissan LEAF creates less CO2 than Toyota Prius hybrid in west US and Texas, but more in N. Midwest

Regionally specific lifecycle CO 2 emissions per mile traveled for plug-in hybrid electric vehicles (PHEVs) and battery electric vehicles (BEVs) in the US can vary widely based on grid emission factors (i.e., the “carbon footprint” of electricity production and use), according to a new study by researchers at Carnegie Mellon University. 12 more words
