High-GWP Refrigerants - California Air Resources Board
High-global warming potential (high-GWP) refrigerants include all ozone-depleting substances and any refrigerant with a GWP of 150 or higher. What is Global Warming Potential? Global Warming Potential, or GWP, is a measure of how destructive a climate pollutant is.

Dec 30, 2023 · This dataset provides 20- (GWP-20), 100- (GWP-100) and 500-year (GWP-500) GWPs from the 4th (AR4), 6th (AR6) IPCC assessment reports, and 20- (GWP-20) and 100-year (GWP-100) GWPs from the 5th (AR5) report (AR5 provided no 500 yr GWPs).
Understanding Global Warming Potentials | US EPA
Jan 16, 2025 · UNFCCC guidelines now require the use of the GWP values from the IPCC's Fifth Assessment Report (AR5), published in 2013.
(WGIII AR5). The material presented in this annex documents metrics, methods, and common data sets that are typically used across multiple chapters of the report. The annex is composed of three parts: Part I introduces standards metrics and common definitions adopted in the report; Part II presents methods to derive or calculate certain quanti-

Jun 28, 2010 · If we use AR5 values, GWP for methane is 28 times higher than that of CO2. According to the report, the atmospheric abundance of CO2 is 390.5 ppm, whereas for methane that’s 1803.2 ppb.
The Fifth Assessment Report of the IPCC - UNFCCC
Nov 12, 2013 · The Fifth Assessment Report (AR5) of the Intergovernmental Panel on Climate Change (IPCC) was published in 2014. Working Group I, Working Group II, and Working Group III reports were approved in 2013 and 2014 and the Synthesis Report was finalized in October 2014.
