Environmental Protection Agency: Greenhouse Gas Equivalencies Calculator

Did you ever wonder what reducing carbon dioxide (CO2) emissions by 1 million metric tons means in everyday terms?

The greenhouse gas equivalencies calculator can help you understand just that, translating abstract measurements into concrete terms you can understand, such as the annual emissions from cars, households, or power plants.

Please note that these estimates are approximate and intended for communication purposes. They should not be used for emission inventories, formal carbon footprints, or formal emissions analysis. See Other Resources for additional tools that EPA maintains for emissions analysis and Other Calculators for additional calculators that EPA maintains.
