Electric cars tend to produce less carbon pollution than gas-powered ones—but just how much less? Enter your ZIP code below to see how different types of vehicles stack up in your area. Entering a make, model, and year will narrow results to a specific EV model.

What is CO2e?

Shorthand for “carbon dioxide equivalent,” CO2e is a standard unit for measuring all of a vehicle’s greenhouse gas emissions. A higher number of CO2e emissions = more 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.
