On the Chemical Pathways Influencing the Effective Global Warming Potential of Commercial Hydrofluoroolefin Gases
Science
4 Apr 2024 | ChemSusChem
The introduction of hydrofluoroolefins as a low Global Warming Potential substitute for hydrofluorocarbons raised concerns about the long-term atmospheric fate of their primary degradation products, particularly TFE, TFF, and TF due to the potential secondary formation of HFC-23, a potent greenhouse pollutant. This analysis indicates a need for further research to assess the climate risks associated with HFOs.
