The following table includes the 100-year time horizon global warming potentials (GWP) relative to CO2. This table is adapted from the IPCC Fifth Assessment Report, 2014 (AR5)i.

Mar 25, 2025 · The GWP is the ratio of the warming caused by a substance to the warming caused by a similar mass of carbon dioxide. Thus, the GWP of CO2 is defined to be 1.0 . CFC-12 has a GWP of 8,500, while CFC-11 has a GWP of 5,000.

The tables below show the lifetimes and direct (except for CH4) 100-year global warming potentials (GWP) relative to CO2 for ozone-depleting substances and their replacements.

Feb 13, 2023 · “Global warming potential” (GWP) measures a greenhouse gas’s ability to trap heat for 100 years. Carbon dioxide has a global warming potential of one, and other greenhouse gases are measured against it: so methane, which has a GWP of about 25, traps roughly 25 times as much heat over 100 years.

Global Warming Potential (GWP) of Refrigerants: Why are Particular Values Used? Ever since the Montreal Protocol agreed to phase out hydrochlorofluorocarbons (HCFCs), there has been an increasing interest within the Protocol on climate issues. Decision XIX/6, taken in 2007, to adjust the Protocol to accelerate the phase out of

The global warming potential (GWP) is defined as an "index measuring the radiative forcing following an emission of a unit mass of a given substance, accumulated over a chosen time horizon, relative to that of the reference substance, carbon dioxide (CO 2). The GWP thus represents the combined effect of the differing times these substances ...

Jun 7, 2024 · CFCs have a high global warming potential (GWP), meaning they have a much greater ability to trap heat compared to carbon dioxide (CO2). For example, one molecule of CFC-12 has a GWP of approximately 10,900 over a 100 …

Jan 16, 2025 · Chlorofluorocarbons (CFCs), hydrofluorocarbons (HFCs), hydrochlorofluorocarbons (HCFCs), perfluorocarbons (PFCs), sulfur hexafluoride (SF 6) , and nitrogen trifluoride (NF 3) are sometimes called high-GWP gases because, for a given amount of mass, they trap substantially more heat than CO 2.

Global warming potential (GWP) is a measure of how much heat a greenhouse gas (GHG) will trap in the Earth’s atmosphere over a set period. The higher the GWP, the more heat the GHG traps, leading to a warming planet.
