What is your carbon footprint?

Take a few minutes to find out with EPA's Household Carbon Footprint Calculator.

 
Please enter a valid number of people.
Please enter a valid five-digit ZIP Code.
We could not find your ZIP code in our database. Please try again, or you may continue using the calculator with a default value. Using the default will give you average estimates.

About

  • Many of our daily activities - such as using electricity, driving a car, or disposing of waste - cause greenhouse gas emissions. Together these emissions make up a household's carbon footprint.
  • The calculator estimates your footprint in three areas: home energy, transportation and waste. Everyone's carbon footprint is different depending on their location, habits, and personal choices.
  • For an explanation of the calculator's assumptions and sources, see the Assumptions and References page.

How To

  • You can get a quick, rough estimate of your carbon footprint by using U.S. average values. They are provided (along with other useful information) in the "tool tips" throughout the calculator.
  • For a more accurate estimate, use your own numbers. Gather your utility bills (electricity, natural gas, fuel oil, propane) to calculate your average use over a year. You can find your car's rated fuel efficiency at fueleconomy.gov, or you can calculate your car's actual efficiency.

Your Carbon Footprint

Annual CO2 emissions (lbs.) Even though it's a gas, CO2 is measured in units of mass such as pounds, kilograms, and tons. Below are some useful comparisons to put CO2 emissions in context*: 100 lb of CO2 = emissions from burning 5 gallons of gasoline; 500 lb of CO2 = emissions from burning 244 pounds of coal; 1,000 lb of CO2 = emissions from burning 1.1 barrels of oil
