Greenhouse Gas Equivalencies Calculator

Enter Your Data Below

There are two options for entering data into this calculator.
Option 1:

**This calculator uses an eGRID non-baseload national average emissions rate when calculating "kilowatt-hours of electricity" to "carbon dioxide equivalent".

Option 2:

If you have already estimated the quantity of avoided emissions reductions (e.g., metric tons of carbon dioxide equivalent), you can input the amount of avoided emissions and select the appropriate units for the corresponding greenhouse gas type.

Amount Unit Gas
CO2 - Carbon Dioxide
CH4 - Methane
N2O - Nitrous Oxide
- Hydrofluorocarbon gases
- Perfluorocarbon gases
SF6 - Sulfur Hexafluoride
Carbon Equivalent

The sum of the greenhouse gas emissions you entered above is of Carbon Dioxide Equivalent.

Equivalency Results

The information you entered above is equivalent to one of the following statements:

Annual greenhouse gas emissions from passenger vehicles
CO2 emissions from gallons of gasoline consumed
CO2 emissions from barrels of oil consumed
CO2 emissions from tanker trucks’ worth of gasoline
CO2 emissions from the electricity use of homes for one year
CO2 emissions from the energy use of homes for one year
Carbon sequestered by tree seedlings grown for 10 years
Carbon sequestered annually by acres of pine or fir forests
Carbon sequestered annually by acres of forest preserved from deforestation
CO2 emissions from propane cylinders used for home barbeques
CO2 emissions from burning railcars’ worth of coal
Greenhouse gas emissions avoided by recycling tons of waste instead of sending it to the landfill
Annual CO2 emissions of coal fired power plants
