CO2e

Carbon dioxide equivalent is used to measure and compare emissions from greenhouse gases based on how severely they contribute to global warming, i.e. how much a particular gas would contribute to global warming if it was CO2. Gases other than the carbon dioxide are generally expressed in terms of carbon dioxide equivalents.

There are six greenhouse gases listed in the greenhouse gas protocol (see below). 

  • Carbon dioxide (CO2)
  • Methane (CH4)
  • Nitrous oxide (N2O)
  • Hydrofluorocarbons (HFCs)
  • Perfluorocarbons (PFCs)
  • Sulfur hexafluoride (SF6)
