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/21: Potential non-compliance with consumption of Annex A, group I, ozone-depleting substances (CFCs) by Article 5 Parties for the control period 1 July 2001-31 December 2002, and requests for plans of action

The Fifteenth Meeting of the Parties decided in Dec. XV/21:

  1. To note that the following Article 5 Parties have failed to report data for consumption of Annex A, group I, substances for the control period from 1 July 2001 to 31 December 2002, and have reported annual data for 2001 and/or 2002 which are above their requirement for a freeze in consumption: Dominica, Haiti, Saint Kitts and Nevis, and Sierra Leone. In the absence of further clarification, those Parties are presumed to be in non-compliance with the control measures under the Protocol;
  2. To urge those Parties to report data for Annex A, group I, substances for the control period from 1 July 2001 to 31 December 2002 as a matter of urgency and, in addition, for consideration at the next meeting of the Implementation Committee, explanations for their excess consumption, together with plans of action with time-specific benchmarks to ensure a prompt return to compliance. Those Parties may wish to consider including in their plans of action the establishment of import quotas to freeze imports at baseline levels and support the phase-out schedule, a ban on imports of ODS-using equipment, and policy and regulatory instruments that will ensure progress in achieving the phase-out;
  3. To note also, however, the special situation of Haiti, which has only recently ratified the Montreal Protocol and begun to implement its refrigerant management plan;
  4. To monitor closely the progress of those Parties with regard to the phase-out of CFCs. To the degree that those Parties are working towards and meeting the specific Protocol control measures, they should continue to be treated in the same manner as Parties in good standing. In that regard, those Parties should continue to receive international assistance to enable them to meet their commitments in accordance with item A of the indicative list of measures that may be taken by a Meeting of the Parties in respect of non-compliance. Through the present decision, however, the Parties caution those Parties, in accordance with item B of the indicative list of measures, that in the event that any Party fails to return to compliance in a timely manner, the Parties will consider measures consistent with item C of the indicative list of measures. Those measures may include the possibility of actions available under Article 4, such as ensuring that the supply of CFCs (that is, the subject of non-compliance) is ceased and that exporting Parties are not contributing to a continuing situation of non-compliance.
