Ozone Secretariat The Ozone Secretariat coordinates international action on stratospheric ozone depletion and facilitates implementation of the Montreal Protocol and its Amendments, including the Kigali Amendment and the Beijing Amendment. It supports meetings of the Conference of the Parties (Montreal Protocol), the Meeting of the Parties (MOP), the Open-ended Working Group (OEWG), and technical panels such as the Technology and Economic Assessment Panel and the Scientific Assessment Panel. The Secretariat serves as a hub linking national focal points, bilateral donors, multilateral institutions and specialized agencies including the United Nations Environment Programme, the United Nations Development Programme, and the World Meteorological Organization.

History

The Secretariat was established in 1988 following the entry into force of the Vienna Convention for the Protection of the Ozone Layer and the subsequent negotiation of the Montreal Protocol on Substances that Deplete the Ozone Layer. Its creation paralleled global scientific assessments led by figures associated with the World Meteorological Organization and the Intergovernmental Panel on Climate Change, and drew on diplomatic precedents from the United Nations Environment Programme and the United Nations Conference on Environment and Development. Early milestones included coordination during the phasedown of chlorofluorocarbons and the negotiation of the London Amendment, the Copenhagen Amendment, and the Montreal Amendment. The Secretariat’s work intersected with environmental diplomacy at fora such as the Rio Earth Summit and later with climate diplomacy at the United Nations Framework Convention on Climate Change meetings, including the Conference of the Parties (UNFCCC) sessions and the Paris Agreement discussions. Leadership and staff have engaged with scientists from institutions like the National Aeronautics and Space Administration, the National Oceanic and Atmospheric Administration, NASA research programs, and academic centers such as Cambridge University, Massachusetts Institute of Technology, and Scripps Institution of Oceanography.

The Secretariat’s mandate derives from the Vienna Convention and the Montreal Protocol, tasked with servicing Meetings of the Parties, organizing technical panels including the Environmental Effects Assessment Panel and the Implementation Committee, and maintaining treaty records. It administers decision texts, party communications, and data reporting systems used by national ozone officers and by implementing agencies like the Multilateral Fund for the Implementation of the Montreal Protocol, the Global Environment Facility, and donor countries including United States, Japan, Germany, Norway, and Canada. Functional activities include logistics for sessions of the Meeting of the Parties, facilitation of replenishment cycles, dissemination of scientific assessments from bodies like the Scientific Assessment Panel, and coordination with standard-setting bodies such as the International Organization for Standardization and the International Electrotechnical Commission for refrigerant management.

The Secretariat is hosted within the United Nations Environment Programme in Nairobi with a substantive presence in Geneva and links to regional offices spanning Panama, Bangkok, and Addis Ababa. Its organizational design comprises the Executive Officer, professional staff units for legal, scientific, and administrative functions, and policy support for subsidiary bodies including the Technology and Economic Assessment Panel, the Implementation Committee, and the Open-ended Working Group. It liaises with national ozone units in capitals, diplomatic missions to the United Nations, and intergovernmental organizations such as the World Health Organization, the Organisation for Economic Co-operation and Development, and the World Customs Organization. Collaboration extends to research networks like the International Ozone Commission and the Global Atmosphere Watch programme.

Notable initiatives coordinated by the Secretariat include implementation support for phasing down hydrofluorocarbons under the Kigali Amendment, management of surveys on production and consumption reported under the Montreal Protocol, and facilitation of technology transfer through the Multilateral Fund. The Secretariat supports capacity-building projects with partner agencies such as the United Nations Industrial Development Organization, the United Nations Development Programme, and regional development banks including the World Bank and the Asian Development Bank. It organizes global assessment cycles that synthesize work from the Scientific Assessment Panel, the Environmental Effects Assessment Panel, and the Technology and Economic Assessment Panel, while convening special sessions to address issues raised by Parties including illegal trade coordinated with the World Customs Organization and standards bodies such as the International Organization for Standardization.

Operational funding and project finance flow through mechanisms tied to the Multilateral Fund for the Implementation of the Montreal Protocol, assessed contributions from Parties to the United Nations Environment Programme, and voluntary contributions from governments and foundations, including donors such as United States Agency for International Development, the European Commission, Japan International Cooperation Agency, and philanthropic entities. Budgetary oversight involves the United Nations Board of Auditors, internal audit units, and reporting to the Meeting of the Parties where replenishment decisions for the Multilateral Fund and administrative budgets are made.

The Secretariat acts as the primary secretariat to Parties to the Montreal Protocol, maintaining official communication channels with national ozone officers, Permanent Missions to the United Nations, and environment ministries across capitals such as Washington, D.C., Beijing, New Delhi, Brasília, and Moscow. It forges partnerships with international financial institutions including the International Monetary Fund, the World Bank, and regional development banks; technical partnerships with the World Health Organization, Food and Agriculture Organization, and the International Labour Organization; and scientific partnerships with research agencies like the European Space Agency and national academies such as the Royal Society and the National Academy of Sciences.

The Secretariat’s facilitation contributed to global compliance that has led to documented declines in atmospheric concentrations of key ozone-depleting substances monitored by NASA, NOAA, and the World Meteorological Organization’s Global Atmosphere Watch. Its convening role enabled the rapid negotiation of the Kigali Amendment to phase down hydrofluorocarbons, influencing climate mitigation pathways assessed by the Intergovernmental Panel on Climate Change. Over decades, coordinated action under the Montreal Protocol has delivered public health co-benefits reported by the World Health Organization and ecosystem benefits documented in studies by institutions like Woods Hole Oceanographic Institution and Columbia University. The Secretariat’s work remains central to multilateral environmental governance alongside instruments such as the Convention on Biological Diversity and the United Nations Framework Convention on Climate Change.
