Carbon Dioxide Equivalent (CO2e)
CO2e (Carbon Dioxide Equivalent) is a standard unit for measuring and comparing the total greenhouse gas emissions based on their global warming potential relative to carbon dioxide. To calculate CO2e, each greenhouse gas is multiplied by a conversion factor to convert it into a single unit of measure. The specific conversion factors for each greenhouse gas may change over time depending on the concentration of the gas in the atmosphere.
“The factory emitted 1000 kg of nitrous oxide emissions, the equivalent of 298,000 kg CO2e emissions (using a conversion factor of 298 kg N2O/1 kg CO2).”
