That means they didn’t just look at the emissions from the power EVs use, but also the emissions created in manufacturing EVs, in transporting fuel to powerplants, and in extracting fuel. How efficient a gas car would have to be to match the emissions profile of the average EV in each region. That 59 mpg figure isn’t just better than any pure gas car can manage. In many ways, it’s the exact opposite of the gas car paradigm. From then on, each year they offset more and more emissions that an equivalent gas car would have produced.
