Definition
Global Warming Potential (GWP) is a factor describing the radiative forcing impact (degree of harm to the atmosphere) of one unit of a given GHG relative to one unit of CO2.[1]
CO2e is a universal unit of measurement that accounts for the global warming potential (GWP) when measuring and comparing GHG emissions from different gases. The time period generally used for GWP is 100 years. There are also 20-year GWPs that are available. The GWP remains constant for carbon dioxide over different time frames but there is a significant difference in the values of other gases. GWP 20 may be useful to measure impacts of gases.
