The eleventh meeting of the Conference of the Parties to the Vienna Convention (COP 11) and the twenty-ninth Meeting of the Parties to the Montreal Protocol (MOP 29), being held during the thirtieth anniversary of the Montreal Protocol, will meet from 20-24 November 2017 in Montreal, Canada.

The preparatory segment will be held from 20-22 November 2017 and the high-level segment will be held from 23-24 November 2017.

Combined issues to be considered during the preparatory segment include the financial reports and budgets of the trust funds as well as the extension of the trust funds for the Vienna Convention and the Montreal Protocol. The MOP will consider, inter alia: the Kigali Amendment to the Montreal Protocol to phase down hydrofluorocarbons (HFCs); the Multilateral Fund (MLF) replenishment; issues related to Article 2 of the Protocol; use of controlled substances as process agents; energy efficiency; and safety standards relevant to low global-warming-potential alternatives. The COP will consider the report of the tenth meeting of the ozone research managers of the parties to the Vienna Convention and the status of the general trust fund for financing activities on research and systematic observations relevant to the Vienna Convention.

The high-level segment includes presentations by the assessment panels on the status of their work, including latest developments, and by the Chair of the MLF Executive Committee on its work. There will also be a high-level roundtable on identifying future opportunities and priorities, as well as a science event entitled ‘the science of ozone layer depletion and recovery: reflections on the past, present and future.’

The high-level segment will also address the report of the co-chairs of the preparatory segment and consideration of the decisions recommended for adoption by COP 11 of the Vienna Convention and MOP 29 of the Montreal Protocol.
