Why are environmental groups urging the EPA to reject Chemours' Opteon 2P50 PFAS fluid for data center cooling?

The coalition of 17 environmental groups, led by Earthjustice, is petitioning the EPA to reject accelerated approval of Chemours' Opteon 2P50 because they assert Chemours has used 'bad science' to downplay the chemical's toxicity and environmental risks, emphasize that PFAS are 'forever chemicals' with potential for leakage and significant contamination even in closed systems, and highlight concerns about missing toxicological data and Chemours' history of pollution.

What specific concerns do the environmental groups raise about Opteon 2P50's safety and regulatory review?

The coalition raises concerns that Chemours has employed 'bad science' to minimize the toxicity and environmental risks of Opteon 2P50, notes the inherent persistence of PFAS as 'forever chemicals', warns of potential leakage and significant contamination despite use in supposedly closed cooling systems, points to missing toxicological data, and cites Chemours' documented history of pollution as grounds for heightened scrutiny.
