How Carbon Footprint Is Estimated

Your carbon footprint includes emissions from transportation, home energy, and air travel.

Emission Factors Used

  • Driving: 19.6 lbs CO2 per gallon of gasoline
  • Electricity: 0.92 lbs CO2 per kWh (US average)
  • Natural Gas: 11.7 lbs CO2 per therm
  • Flights: ~90 kg CO2 per flight hour per passenger (x 2.2 for lbs)
  • Lösungsbeispiel

    12,000 miles at 28 MPG, 900 kWh/mo electricity, 40 therms/mo gas, 10 flight hours.

    1. 01Driving = 12,000 / 28 x 19.6 = 8,400 lbs CO2
    2. 02Electricity = 900 x 12 x 0.92 = 9,936 lbs CO2
    3. 03Natural gas = 40 x 12 x 11.7 = 5,616 lbs CO2
    4. 04Flights = 10 x 90 x 2.2 = 1,980 lbs CO2
    5. 05Total = 8,400 + 9,936 + 5,616 + 1,980 = 25,932 lbs = 11.8 tonnes

    Häufig Gestellte Fragen

    What is the average carbon footprint in the US?

    The average American produces about 16 metric tonnes of CO2 per year, one of the highest per-capita rates in the world. The global average is about 4 tonnes.

    How can I reduce my carbon footprint?

    Drive less or switch to an EV, improve home insulation, use renewable energy, fly less, eat less meat, and reduce waste.

    What is a carbon offset?

    Carbon offsets fund projects that reduce emissions elsewhere (tree planting, renewable energy, methane capture) to compensate for your own emissions.
