Calculate your emissions.
- EPA’s Personal Emissions Calculator
Estimate your personal greenhouse gas emissions or your family’s greenhouse gas emissions.
- Climate Change Calculator
Determine the CO2 generated by your use of fossil fuels & the number of trees it will take to remove that amount of CO2.
- Greenhouse Gas Equivalencies Calculator
Translate greenhouse gas (GHG) reductions from units that are typically used to report reductions (e.g., metric tons of carbon dioxide equivalent) into terms that are easier to conceptualize (e.g., equivalent number of cars not driven for one year).
- What fuel is used to produce the electricity I use?
U.S. electricity is generated in many different ways, with a wide variation in environmental impact.

|Electricity: National average emissions factor for electricity is 1.37 pounds CO2 per kilowatt-hour. Every kilowatt-hour of electricity saved keeps 1.5 to 2 pounds of CO2 out of the atmosphere.1|
|Carbon coefficient for natural gas: 117 pounds of CO2 per million BTU, or 0.12 pounds per cubic foot of gas. Each therm (gas heat): 1 therm of natural gas leads to emission of 11.7 lbs. of CO2.2|
|Carbon coefficient for distillate fuel (fuel oil): 161.44 pounds of CO2 per million BTU, or 22.29 pounds per gallon. Each gallon of gas burned produces 20 pounds of C02 for cars and 21 pounds of C02 for trucks/vans.2|
|Note: The average per person emissions estimates or per capita emissions estimates are usually derived from national estimates of GHG emissions, which include GHG emissions from all sources in the U.S., including industrial emissions (emissions from manufacturing of goods and services)3|
|Converting Between Carbon Dioxide Equivalents and Carbon Equivalents
To convert from CE to CO2e, multiply by 44/12
To convert from CO2e to CE, multiply by 12/44
The conversion between CO2e and CE is directly related to the ratio of the atomic mass of a carbon dioxide molecule to the atomic mass of a carbon atom (44:12).

|Natural gas-fired Power Plants||The average emissions rates in the United States from natural gas-fired generation are: 1135 lbs/MWh of carbon dioxide, 0.1 lbs/MWh of sulfur dioxide, and 1.7 lbs/MWh of nitrogen oxides.
Note: Compared to the average air emissions from coal-fired generation, natural gas produces half as much carbon dioxide, less than a third as much nitrogen oxides, and one percent as much sulfur oxides at the power plant.
|Oil-fire Power Plants||The average emissions rates in the United States from oil-fired generation are: 1672 lbs/MWh of carbon dioxide, 12 lbs/MWh of sulfur dioxide, and 4 lbs/MWh of nitrogen oxides.|
|Coal-fired Power Plants||The average emission rates in the United States from coal-fired generation are: 2,249 lbs/MWh of carbon dioxide, 13 lbs/MWh of sulfur dioxide, and 6 lbs/MWh of nitrogen oxides.|
|Nuclear Power Plants||Nuclear power plants do not emit carbon dioxide, sulfur dioxide, or nitrogen oxides.|
|Electricity generation is the dominant industrial source of air emissions in the United States today.|
|Fossil Fuel-fired Power Plants||Fossil fuel-fired power plants are responsible for 67 percent of the United State’s sulfur dioxide emissions, 23 percent of nitrogen oxide emissions, and 40 percent of man-made carbon dioxide emissions.|
