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.

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

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

Montreal Protocol MOP 28

MOP 28’s primary decision was to adopt the Kigali Amendment, which amended the Protocol to include hydrofluorocarbons (HFCs) as part of its ambit. MOP 28 also adopted a number of substantive and procedural decisions.

37th Meeting of the Open-Ended Working Group of the Parties to the Montreal Protocol

Delegates made slow and steady progress throughout the week, with many lauding discussions for moving from a general nature to addressing specific challenges. Although the contact group was not able to complete its mandate, a sense of optimism remained after the closing session with expectations that the next round of negotiations would continue to make significant progress and provide concrete steps towards adopting an amendment on HFC management in 2016.
