The Montreal Protocol on Substances that Deplete the Ozone Layer

The Montreal Protocol on Substances that Deplete the Ozone Layer is a global agreement to protect the Earth’s ozone layer by phasing out the chemicals that deplete it. This phase-out plan includes both the production and consumption of ozone-depleting substances. The landmark agreement was signed in 1987 and entered into force in 1989.

The parties to the Protocol meet once a year to make decisions aimed at ensuring the successful implementation of the agreement. These include adjusting or amending the Protocol, which has been done six times since its creation. The most recent amendment, the Kigali Amendment, called for the phase-down of hydrofluorocarbons (HFCs) in 2016. These HFCs were used as replacements for a batch of ozone-depleting substances eliminated by the original Montreal Protocol. Although they do not deplete the ozone layer, they are known to be powerful greenhouse gases and, thus, contributors to climate change.

The Montreal Protocol provided a set of practical, actionable tasks that were universally agreed on. The Protocol has successfully met its objectives thus far and continues to safeguard the ozone layer today. Thanks to the collaborative effort of nations around the world, the ozone layer is well on its way to recovery.

Decision XV/27: Non-compliance with the Montreal Protocol by Armenia

The Fifteenth Meeting of the Parties decided in Dec. XV/27:

  1. To note that Armenia has now been reclassified as a developing country under decision XIV/2 of the Fourteenth Meeting of the Parties;
  2. To note that ratification of the London Amendment is a precondition for Multilateral Fund funding, and therefore to call upon Armenia expeditiously to complete its process of ratification of the London Amendment;
  3. To note further, however, that despite the absence of financial assistance, Armenia has reported data showing it to be in compliance with the freeze on CFC consumption, and to congratulate Armenia on its achievements.
