How Clean is Your Electric Vehicle?
On average, electric vehicles (EVs) produce less carbon pollution than comparable gasoline-fueled cars. Just how much less depends on where they’re charged.
As the US electricity grid gets cleaner (by shifting away from coal and gas, and by adding solar and wind power), the benefits of EVs compared with gasoline vehicles will continue to grow.
How much global warming pollution is your EV responsible for? Enter your ZIP code, then a make, model, and year, to see how your car stacks up.
What is MPG-CO2e?
Shorthand for “miles-per-gallon carbon dioxide equivalent,” MPG-CO2e is a standard way to understand and compare emissions from electric vehicles. Specifically, it is the fuel economy a gas-powered car would have to achieve to generate an equivalent amount of pollution. A higher MPG-CO2e = less global warming pollution.
What if I charge from clean electricity?
The exact emissions from charging an EV depend on the electricity sources used to charge it. In this tool, we determine the average emissions from electric utilities at a regional level, and use your ZIP code to identify what region you’re in. If you charge with renewable energy (like wind or solar), or participate in green power programs, your driving can be virtually emissions free.
