The California Air Resources Board (CARB) will hold a public workshop to discuss proposal for reducing high-global warming potential hydrofluorocarbon refrigerant emissions.
At the workshop, CARB staff will present an overview of reduction efforts to date, and next steps on the HFC mitigation strategies identified in the Short Lived Climate Pollutant (SLCP) Strategy. As next steps, CARB is considering:
Prohibiting refrigerants with a GWP of 750 or greater in new stationary air‑conditioning systems starting January 1, 2023.
Limiting the use of refrigerants with high GWP values in stationary refrigeration systems.
