The 2016 Kigali Amendment: 

  • Added HFCs to the list of controlled substances; 
  • Set a timeline for their gradual reduction by 80-85% by the late 2040s. The first reductions by developed countries are expected in 2019, with developing countries to follow with a freeze of HFC consumption levels in 2024 and in 2028 for some nations.
