The IIR is pursuing its mission to disseminate and popularise knowledge about refrigeration and sustainable development by posting a new article on its website.
Based on the latest updated data fromUNEP's RTOC 2022 report, to which the IIR contributed as a reviewer, the article provides a brief definition and contextualisation of global warming potential (GWP) before presenting a summary table.
The table gives 100-year and 20-year GWP values for HFC refrigerants, including both pure HFCs and blends containing at least one HFC in their composition.
Consult the table in the Encyclopedia
