Annex II. IPCC Global warming potential values
This annex provides 100-year time horizon global warming potential (GWP) values from the Intergovernmental Panel on Climate Change (IPCC). The table below is adapted from the IPCC Sixth Assessment Report, 2020 (AR6)
The AR6 values are the most recent, but the Fourth Assessment Report (2007) and Fifth Assessment Report (2014) values are also provided because they are sometimes used for inventory and reporting purposes. The use of the latest values (AR6) is recommended. IPCC also publishes 20-year and 500-year time horizon GWPs but these are not included in this annex. For more information, refer to the original IPCC data sources:
