Enter your ZIP Code, Miles Driven Per Year, and EV Efficiency to calculate your EV Annual CO₂ Emissions — then add a Gas Car Fuel Efficiency to see your Annual CO₂ Reduction and exactly how much cleaner your electric drive really is.

Tailpipe emissions are the greenhouse gases your car produces while driving. For gas cars, this includes CO₂ from burning fuel. EVs have zero tailpipe emissions. Upstream emissions are the greenhouse gases from producing and distributing gasoline or electricity. This calculator includes both types for a complete comparison.
Your ZIP code determines your regional electricity grid composition. Areas with more coal power have higher emissions per kWh, while regions with more renewable energy sources like wind, solar, or hydroelectric have lower emissions. This significantly affects your EV's carbon footprint.
This calculator focuses on fully electric vehicles (BEVs) versus traditional gas cars. For plug-in hybrids (PHEVs), you would need to estimate what percentage of miles are driven on electric power versus gas, then calculate each portion separately.
The calculator uses EPA and EIA data for regional electricity grid emissions and standard conversion factors. Results are estimates based on average values and may vary depending on specific vehicle models, driving conditions, and actual electricity sources.
No, this calculator focuses on operational emissions from driving the vehicles. It does not include lifecycle emissions from manufacturing, battery production, or vehicle disposal, which can vary significantly between models and manufacturers.
If you primarily charge with solar or other renewable energy, select the appropriate electricity source option. Solar charging typically results in near-zero operational emissions for your EV, maximizing the environmental benefits.
Choose a more efficient EV model, charge during times when renewable energy is more prevalent on the grid, install home solar panels, reduce overall driving through trip planning, and advocate for cleaner electricity sources in your region.
