Researchers sound further warnings about HFOs

A new report from the German Environment Agency, and research from the University of New South Wales have raised more concerns about the environmental impacts of HFO refrigerants. When hydrofluorocarbons (HFCs) were identified as greenhouse gases, and targeted for phase-down under the Kigali Amendment to the Montreal Protocol, hydrofluoroolefins (HFOs) were put forward as an […]

Tensions rise over EU refrigerant transition

Debate is intensifying in Europe over the future of HFCs as the European Union eyes stricter limits on the global warming potential of refrigerants, and manufacturers push back on the proposed switch to hydrocarbons. The European Union (EU) is in the process of reviewing its F-Gas Regulation, which provides a roadmap for phasing down fluorinated […]

Chemours pledges to reduce HFC-23 emissions

Global chemistry company and refrigerant producer Chemours has announced a project to significantly reduce emissions of HFC-23 at its Louisville, Kentucky (US) manufacturing site. HFC-23 is a potent greenhouse gas with a 100-year global warming potential (GWP) of 12,400 – many times greater than most refrigerants used today. It is a by-product of producing R22, […]
