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.
2.10.2 Direct Global Warming Potentials - AR4 WGI Chapter 2: …
All GWPs depend on the AGWP for CO 2 (the denominator in the definition of the GWP). The AGWP of CO 2 again depends on the radiative efficiency for a small perturbation of CO 2 from the current level of about 380 ppm.

IPCC AR4, AR5, and AR6 20-, 100-, and 500-year GWPs
2023年12月30日 · IPCC AR4, AR5, and AR6 20-, 100-, and 500-year GWPs Metadata Updated: December 30, 2023 The International Panel for Climate Change (IPCC) produces regular Assessment Reports that provide global warming potentials (GWPs) for greenhouse gases (GHG) in the context of multiple time horizons including 20, 100, and 500 years.
• AR4 recommends that Radiative Forcing Index (RFI) introduced in IPCC (1999) should not be used as an emission metric does not account for the different lifetimes of different forcing agents. • Revised GWP concept including efficacy of forcing agent efficacies are less uncertain than climate sensitivities
Global warming potential (GWP) is intended as a quantified measure of the globally averaged relative radiative forcing impacts of a particular greenhouse gas. It is defined as the cumulative radiative forcing–both direct and indirect effects–

GWPs are calculated using a set time horizon. All GWPs used for GHG inventory purposes are considered over a 100-yr timeframe. GWPs are updated periodically with improvements to the underlying science. CARB uses 2007 IPCC AR4 GWPs for the current emissions inventory.
