HFO-1234yf will contribute cumulative emissions of 1.7Gt during 2024–2060, while the cumulative amount of TFA deposition from HFO-1234yf emissions will reach 0.4–1.0Gt, the study says
Arctic ice studies and other research point to growth of TFA, widely considered a PFAS, in the environment.
But PEER is continuing its lawsuit to determine why EPA used that PFAS definition.
Stakeholders can provide feedback on the bill through July 3.
ATMOsphere will convene PFAS experts at the Montreal Protocol meeting to explain the European approach to the PFAS Restriction Proposal.
Panelists will discuss EPA’s narrow definition of PFAS, which excludes refrigerants and their TFA atmospheric degradation product.
Trifluoroacetic Acid (TFA) is formed from the atmospheric breakdown of refrigerants HFO-1234yf and HFC-134a.
