The United States Court of Appeals for the District of Columbia Circuit rejected an appeal brought by refrigerant manufacturers Chemours and Honeywell, in addition to the Natural Resources Defense Council (NRDC), on the courts decision to overturn a ban on the usage of HFC refrigerants.
In 2015, the EPA ruled to ban high GWP refrigerants including R404A, R134a, R407C and R410A from use in certain new products as early as January 1, 2021.
Refrigerant manufacturers Mexichem and Arkema appealed the 2015 ruling, claiming that the EPA could not use a section of the Clean Air Act to target HFCs. The US Court of Appeals for the District of Columbia agreed, and in August last year decided 2-1 in favor of the appeal, discontinuing the ban on HFC’s.
While this court decision slows efforts to phaseout HFC’s, states like California are creating their own phase-down schedules and other states are likely to follow. There is also uncertainty on whether the Trump administration will ratify the Kigali Amendment, which met it’s 20-country threshold for ratification in November of 2017.
