GWP is 1 for CO2. For other gases it depends on the gas and the time frame. Carbon dioxide equivalent (CO2e or CO2eq or CO2-e) is calculated from GWP. For any gas, it is the mass of CO2 that would warm the earth as much as the mass of that gas. Thus it provides …

Web2.15.7.1 Global Warming Potential. The GWP is a number that refers to the amount of global warming caused by a substance.
