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 XVI/22: Non-compliance with the Montreal Protocol by Chile

The Sixteenth Meeting of the Parties decided in Dec. XVI/22:

  1. To note that Chile has reported annual data for the controlled substances in Annex B, group I (other fully halogenated CFCs), Annex B, group III (methyl chloroform), and Annex E (methyl bromide) for 2003 which are above its requirements for those substances. As a consequence, for 2003, Chile was in non-compliance with its obligations under Articles 2C, 2E and 2H of the Montreal Protocol;
  2. To request Chile, as a matter of urgency, to submit a plan of action with time-specific benchmarks to ensure a prompt return to compliance. Chile may wish to consider including in its plan of action the establishment of import quotas to freeze imports at baseline levels and support the phase-out schedule, and policy and regulatory instruments that will ensure progress in achieving the phase-out;
  3. To monitor closely the progress of Chile with regard to the phase-out of other CFCs, methyl chloroform and methyl bromide. To the degree that Chile is working towards and meeting the specific Protocol control measures, it should continue to be treated in the same manner as Parties in good standing. In that regard, Chile should continue to receive international assistance to enable it to meet its 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 Meeting of the Parties cautions Chile, in accordance with item B of the indicative list of measures, that, in the event that it fails to return to compliance in a timely manner, the Meeting of 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 other CFCs, methyl chloroform and methyl bromide (that is, the subject of non-compliance) is ceased and that exporting Parties are not contributing to a continuing situation of non-compliance.
