Lynn L. Bergeson, “Chemical Compliance: Montreal Protocol Addresses HFCs,” Chemical Processing, November 28, 2016.

October 15, 2016, was a historic day for international climate action: nearly 200 countries reached an agreement to phase out use of hydrofluorocarbons (HFC) at the 28th meeting of the parties to the Montreal Protocol in Kigali, Rwanda. This column summarizes this historic event and its implications.

The Montreal Protocol is the international treaty designed to protect the earth’s ozone layer by requiring the phasing out of production and use of chlorofluorocarbons (CFC), substances believed to contribute to ozone depletion, many of which also contribute to greenhouse gas (GHG) production. By many accounts, the Montreal Protocol is one of the most successful international agreements ever implemented.
