One of the most common questions I’m asked about electric cars is, “how clean are they?”
Five years ago, UCS answered this question, publishing its first look at the global warming emissions from electric vehicles (EVs) in our ‘State of Charge’ report. In early 2017, the US EPA updated their data on emissions from electricity generation, now capturing power plant emissions through the end of 2014. How does this new data change our assessment of EVs?
