The phase down in gasses will begin January 1, 2022. It requires the reduction of production and consumption of HFCs and will mostly impact FM-200 (HFC-227ea) and ECARO-25 (HFC-125). It's important to know this is a phase down and not a phase out. It’s not a complete elimination of HFC chemistries but it will affect the availability and the price of HFC gasses.
