TeachMeFinance.com - explain Carbon Dioxide Equivalent Carbon Dioxide Equivalent The term 'Carbon Dioxide Equivalent' as it applies to the area of energy can be defined as ' The amount of carbon dioxide by weight emitted into the atmosphere that would produce the same estimated radiative forcing as a given weight of another radiatively active gas. Carbon dioxide equivalents are computed by multiplying the weight of the gas being measured (for example, methane)by its estimated global warming potential (which is 21 for methane).'Carbon equivalent units' are defined as carbon dioxide equivalents multiplied by the carbon content of carbon dioxide (i.e., 12/44)'. The term 'Carbon Dioxide Equivalent' as it applies to the area of the environment can be defined as '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. The use of carbon equivalents (MMTCE) is declining'.
