Vienna Convention and Montreal Protocol on Substances that Deplete the Ozone Layer

Concerns the Earth’s stratospheric ozone layer could be at risk from chlorofluorocarbons (CFCs) and other anthropogenic substances first arose in the early 1970s. By 1985, scientific understanding of ozone depletion and its impacts on human health and the environment had advanced. In response, governments adopted the Vienna Convention for the Protection of the Ozone Layer—a framework convention that lays out agreed principles to combat this ozone depletion. It does not, however, require countries to take control actions to protect the ozone layer.

In September 1987, efforts to negotiate binding obligations to reduce use of ozone depleting substances led to the adoption of the Montreal Protocol on Substances that Deplete the Ozone Layer. The Montreal Protocol phases out both the production and consumption of ozone-depleting substances. The Protocol has been adjusted or amended six times since its creation, most recently by the Kigali Amendment in 2016.

4th Extraordinary Meeting of the Parties to the Montreal Protocol (ExMOP-4) and 1st Part of the 43rd Meeting of the Open-ended Working Group (OEWG43)

Parties met online to address issues around funding the Multilateral Fund for Implementation of the Montreal Protocol, agreeing to facilitate payments until replenishment negotiations are complete later this year, and provide guidance to the Replenishment Task Force.

Conference of the Parties (COP) 21 May 2021 - 25 May 2021

12th Meeting of the Conference of the Parties to the Vienna Convention (Part I) and 32nd Meeting of the Parties to the Montreal Protocol

As the meeting closed, delegates agreed that the meeting sent an important signal that despite difficulties caused by the COVID-19 pandemic, the goals of the Montreal Protocol are well on track and, while virtual meetings are difficult, they showed that if something should be done, it can be done.

Conference of the Parties (COP) 23 November 2020 - 27 November 2020

42nd Meeting of the Open-ended Working Group of the Parties to the Montreal Protocol on Substances that Deplete the Ozone Layer (OEWG 42)

This online technical session addressed the Technology and Economic Assessment Panel (TEAP) Replenishment Task Force’s (RTF) report on the replenishment of the Multilateral Fund (MLF) for 2021-2023, which is essential to the continued success of the Montreal Protocol in phasing out ozone depleting substances and greenhouse gases.

Event 14 July 2020 - 16 July 2020

31st Meeting of the Parties to the Montreal Protocol on Substances that Deplete the Ozone Layer (MOP 31)

Delegates to the 31st Meeting of the Parties to the Montreal Protocol successfully completed five days of negotiations, with the most pressing agenda items—terms of reference for the study on the 2021-2023 replenishment of the Multilateral Fund, the unexpected emissions of trichlorofluoromethane (CFC-11), and the areas of focus for the 2022 quadrennial assessment reports of the three Assessment Panels—requiring careful negotiation to balance different parties’ agendas. 

Conference of the Parties (COP) 4 November 2019 - 8 November 2019

41st Meeting of the Open-Ended Working Group of the Parties to the Montreal Protocol on Substances that Deplete the Ozone Layer (OEWG 41)

Event 1 July 2019 - 5 July 2019

30th Meeting of the Parties to the Montreal Protocol on Substances that Deplete the Ozone Layer

MOP 30 adopted 21 decisions on: issues important to the January 2019 entry into force of the Kigali Amendment on Hydrofluorocarbons (HFCs), including data reporting issues, including timeline and revised reporting forms, ways to report mixtures and blends, and setting global warming potential (GWP) values for HCFC-123, HCFC-124, HCFC-141, and HCFC-142

Event 5 November 2018 - 9 November 2018

Workshop on Energy Efficiency Opportunities While Phasing-Down Hydrofluorocarbons (HFCs) and 40th Meeting of the Open-Ended Working Group of the Parties to the Montreal Protocol on Substances that Deplete the Ozone Layer

During OEWG 40, delegates considered the outcomes of this workshop and the report by the Technology and Economic Assessment Panel (TEAP) on energy efficiency in the refrigeration, air-conditioning and heat pump sectors, and how to take up energy efficiency opportunities while phasing down HFCs under the Protocol in the future. Much of OEWG 40 focused on addressing appropriate action in response to an unexpected increase in trichlorofluoromethane (CFC-11) emissions
