Comparison: Your Car vs. an Electric Vehicle
How does your gasoline vehicle compare to a typical electric vehicle for greenhouse gas emissions?
Input your vehicle’s approximate miles per gallon (MPG) and annual mileage below. Results show annual carbon dioxide (CO2) emissions in metric tons.

The results presented are estimates. For a more detailed assessment of total greenhouse gas (GHG) emissions from a specific electric vehicle and a typical gas vehicle using regional grid values, visit Greenhouse Gas Emissions from Electric and Plug-In Hybrid Vehicles.
Assumptions
Total GHG emissions = tailpipe + upstream emissions. Upstream emissions include the GHGs associated with the production and distribution of gasoline and electricity.
- Tailpipe-CO2 Emissions from a gallon of gasoline = 8,887 grams CO2/ gallon
- Upstream-Tailpipe CO2 emissions are multiplied by a national average factor of 1.25 to account for emissions associated with gasoline production, e.g., drilling, refining, and transportation, etc.
For a “typical” electric vehicle: the Model Year 2025 median energy consumption is 39 kWh/100 miles (combined city/hwy) using the national average electricity CO2 emission factor from eGRID 2023.
