The supermarket refrigeration sector is sensing the demise of high-GWP HFCs for use in HVAC systems, including some of the most commonly used refrigerants, R-404A and -507. Even if the line between high- and low-GWP HFCs has yet to be drawn, the industry is considering low-GWP options more frequently.
