How to Calculate Home Energy Emissions

Home energy emissions come from the fuels used to power and heat your home.

Emission Factors

  • Electricity: 0.92 lbs CO2/kWh (US grid average)
  • Natural Gas: 11.7 lbs CO2/therm
  • Heating Oil: 22.4 lbs CO2/gallon
  • Propane: 12.7 lbs CO2/gallon

    • Formula

    Total CO2 = Sum of (Usage * Emission Factor) for each fuel / 2,204.6

    Exemple Résolu

    A home using 900 kWh/month electricity, 40 therms/month gas, no oil or propane.

    1. 01Electricity: 900 * 12 * 0.92 = 9,936 lbs CO2
    2. 02Natural Gas: 40 * 12 * 11.7 = 5,616 lbs CO2
    3. 03Total: 15,552 lbs / 2,204.6 = 7.06 metric tons/year

    Questions Fréquentes

    What is the biggest source of home emissions?

    For most US homes, electricity and natural gas heating are the two largest sources. Switching to renewable electricity can cut home emissions by 40-60%.

    How does the electricity emission factor vary?

    It depends on your regional grid mix. Coal-heavy areas exceed 1.5 lbs/kWh while hydro-heavy regions may be below 0.2 lbs/kWh.

    Does a heat pump reduce emissions?

    Yes. A heat pump is 2-4x more efficient than direct combustion, significantly cutting heating emissions especially with cleaner grid electricity.
