On 15 October 2016, in Kigali, the parties to the Mon- treal Protocol on Substances that Deplete the Ozone Layer (the Montreal Protocol) reached agreement at their 28th Meeting to phase down consumption and production of hydrofluorocarbons (HFCs). They adopted an amendment (the Kigali Amendment) in Decision XXVIII/1. This briefing note has been prepared by the Secretar- iat of the Montreal Protocol to help Parties to the Pro- tocol prepare for ratification, acceptance, or approval of the Kigali Amendment.
