Why are 17 environmental groups urging the EPA to reject Chemours' application for Opteon 2P50?

The coalition, led by Earthjustice, argues that Chemours' science is flawed—specifically minimizing Opteon 2P50's harm and global warming potential—and that the company is seeking to exploit expedited regulatory review. They warn the PFAS-based coolant poses unacceptable risks to human health and the environment, especially given widespread existing PFAS contamination in U.S. drinking water and heightened exposure risks for nearby communities and workers.

What specific concerns do the environmental groups raise about Opteon 2P50 and its use in data centers?

The groups express concern that Opteon 2P50—a PFAS-based coolant—is part of the 'forever chemicals' class known for extreme persistence, bioaccumulation, and toxicity; they warn its deployment in data centers would increase PFAS contamination in surrounding areas and elevate occupational exposure for workers, compounding an already critical public health issue as many Americans already face PFAS-contaminated drinking water.
