Wherever They Charge, Electric Car Emissions Are Less Than Gas-Powered Cars

Fact: Electric cars are better for the climate, no matter how they are charged

Myth: EVs are charged on fossil fuels, so there’s no climate benefit.

Explanation: For all Americans, plugging in anywhere in the United States, the average new EV produces far fewer greenhouse gas emissions than the average new gasoline car. Convention internal combustion engines produce more greenhouse gases in all regions than electric car emissions released by power generating resources to charge the vehicles.  

Conclusive research by Bloomberg New Energy Finance (BNEF) found that in 2018, carbon dioxide emissions from battery-powered vehicles were about 40 percent lower than for internal combustion engines last year. Even in regions with electric grids most reliant on coal, such as China, EVs were responsible for fewer greenhouse gas emissions.

Furthermore, according to the Union of Concerned Scientists, who conducted a landmark “well-to-wheel” life cycle analysis of electric vehicles, EVs are always more climate-friendly, even while factoring in manufacturing, operation, and disposal.

It’s true that the emissions from charging an EV will vary considerably depending on where you plug in. But as this UCS map shows, charging an EV off of the dirtiest grids in the country (in and around Colorado and Kansas) yield global warming pollution equivalent to driving a 35 mile-per-gallon gasoline-powered car.

In California, where over 40% of the nation’s EVs have been sold, driving an EV produces emissions equal to a gasoline car that achieves 87 mpg.
