Carbon Footprint Calculator: Estimate Your CO2 Emissions
Estimate your annual CO2 emissions based on your car usage and energy habits.
What is a Carbon Footprint?
A carbon footprint is the total amount of greenhouse gases (including carbon dioxide and methane) that are generated by our actions. Personal transportation is often one of the largest contributors to an individual's footprint.
How Driving Emissions Are Calculated
- Determine the total gallons of fuel used (Miles Driven ÷ MPG).
- Multiply gallons by the CO2 coefficient per gallon.
- Burning 1 gallon of gasoline produces approximately 19.6 lbs (8.887 kg) of CO2.
- The result is your annual emission weight.
