Carbon dioxide equivalent (CO2e / CO2-eq)
A metric measure used to compare the emissions from various greenhouse gases based upon their global warming potential (GWP). Carbon dioxide equivalents are commonly expressed as: million metric tons of carbon dioxide equivalents (MMTCO2Eq). The carbon dioxide equivalent for a gas is derived by multiplying the tons of the gas by the associated GWP.
MMTCO2Eq = (million metric tons of a gas) x (GWP of the gas)
