Myth Busted: Electric Cars Versus Diesel

Transcript

Are electric cars dirtier than diesel? Generally, no, when you count the full life cycle. Electric cars do start with a real emissions penalty, because battery production is energy-intensive. The International Council on Clean Transportation estimates that production emissions are about forty percent higher than for combustion cars. But lower emissions from driving usually outweigh that penalty. In its European comparison, an electric car produces roughly sixty-three grams of carbon dioxide equivalent per kilometer over its life, versus about two hundred thirty-four for diesel. The extra production emissions are offset after roughly seventeen thousand kilometers, typically within one to two years. The caveats matter: results depend on grid carbon intensity, vehicle and battery size, and mileage. Electric cars are not emissions-free, but they are generally lower-emission over their full life than diesel.
