WebSep 10, 2024 · The 100-year Global Warming Potential (GWP-100) has extensively been employed in climate policy to report emissions of different greenhouse gases on the same scale. If the evolution of the individual GHGs are not known, this can make it difficult to evaluate how a given global multi-gas emission pathway specified only in CO 2 … WebSep 4, 2012 · The “global warming potential” (or “GWP”) of a GHG indicates the amount of warming a gas causes over a given period of time (normally 100 years). GWP is an index, with CO 2 having the index value of 1, and the GWP for all other GHGs is the number of times more warming they cause compared to CO 2 .

Some GHGs may last only for a short while in our atmosphere but have a much higher heat-trapping potential compared to CO 2 (i.e., methane). This ...
WebGlobal Warming Potentials (GWPs) indicate the relative effectiveness of GHGs in trapping the Earth’s heat over a certain time horizon. CO 2 is used as the reference gas and has a GWP of one. 4 For example, the 100-year GWP of SF 6 is 23,500, indicating that its radiative effect on a mass basis is 23,500 times that of CO 2 over the same time ...
