The Kigali Amendment to the Montreal Protocol establishes a global structure for the phasedown of hydrofluorocarbons (HFCs). Under the amendment, countries committed to cut the production and consumption of HFCs by more than 80 percent over the next 25 years. The phasedown puts a maximum cap on the production of new, virgin refrigerant, so the only way to keep old machines operational will be to reclaim the old refrigerant.
