Enter your ZIP Code, annual miles driven, and your gas vehicle's MPG alongside your EV efficiency and electricity source to calculate your annual CO₂ savings — plus see how your gas vehicle emissions stack up against EV emissions and how many equivalent trees your switch is worth.

Tailpipe emissions are the greenhouse gases your car produces when driving. Upstream emissions are the GHGs associated with the production and distribution of gasoline and electricity used to power the vehicle.
GHG emissions vary by region based on how electricity is produced. For example, electricity from coal results in higher emissions than electricity from renewable sources like wind or solar.
The calculations use EPA emission factors and regional electricity grid data to provide realistic estimates. Actual savings may vary based on driving patterns, vehicle efficiency, and local electricity sources.
EV emissions depend primarily on how the electricity is generated in your region, the efficiency of the electric vehicle, and your driving patterns. Areas with cleaner electricity grids show greater emission reductions.
Most drivers can reduce transportation emissions by 50-80% by switching to an EV, even accounting for electricity generation. The exact reduction depends on your current vehicle's efficiency and local electricity sources.
EVs have zero tailpipe emissions but do have upstream emissions from electricity generation. However, they typically produce significantly fewer total emissions than gas vehicles, especially as the electrical grid becomes cleaner.
The average American drives about 12,000 miles per year. However, you can adjust this number based on your actual driving habits for more accurate CO₂ savings estimates.
You can find your vehicle's EPA-estimated MPG on the fuel economy sticker or by visiting fueleconomy.gov. For more accuracy, calculate your actual MPG by dividing miles driven by gallons used over several fill-ups.
