UNFCCC Secretariat
UN treaty secretariat for the United Nations Framework Convention on Climate Change (adopted 1992, in force 1994). Administers the Warsaw Framework for REDD+ (COP 19, 2013), the methodological framework that national forest reference levels and forest monitoring systems must follow to access results-based payments for deforestation emission reductions. Does not operate satellites or produce EO data; mandates national forest monitoring systems that must use remote sensing combined with ground-based inventory.
The UNFCCC Secretariat is the United Nations administrative body established under Article 8 of the UN Framework Convention on Climate Change, adopted 9 May 1992 in New York and in force from 21 March 1994.[^unfccc-treaty-un] Based on the UN Campus in Bonn, Germany since 1996, the secretariat supports approximately 450 staff and serves 198 parties across three treaty regimes: the Convention, the 1997 Kyoto Protocol, and the 2015 Paris Agreement.[^unfccc-secretariat-about]
The secretariat's institutional role is governance and facilitation, not data production. It supports the Conference of the Parties (COP) as supreme decision body, and the CMA (Paris Agreement) and CMP (Kyoto Protocol) as parallel treaty bodies, plus subsidiary bodies SBSTA and SBI. Executive Secretary Simon Stiell of Grenada has led the secretariat since August 2022.[^unfccc-secretariat-about]
Three UNFCCC-administered frameworks create direct demand for Earth observation data. The Enhanced Transparency Framework (ETF), grounded in Article 13 of the Paris Agreement, requires all parties to submit Biennial Transparency Reports including national GHG inventory reports built on 2006 IPCC Guidelines.[^paris-agreement-page] The Global Stocktake (Article 14, Decision 19/CMA.1) reviews collective climate progress every five years; the first concluded at COP28 in 2023, and the second cycle runs 2026-2028. CEOS and CGMS deliver annual statements to the SBSTA and provide climate data records and Essential Climate Variables through a dedicated GST Portal to inform stocktake inputs.
The strongest explicit EO mandate in the UNFCCC framework is REDD+, which governs reducing emissions from deforestation and forest degradation in developing countries.[^redd-platform-home] Under the Warsaw Framework for REDD+ (seven decisions at COP19, 2013), countries seeking results-based payments must establish national forest monitoring systems that use a combination of remote sensing and ground-based forest carbon inventory approaches, a direct policy requirement for satellite or airborne forest observation (Decisions 4/CP.15, 1/CP.16, 11/CP.19).[^redd-nfms] Measurement, reporting, and verification of forest-related emissions must satisfy Decision 14/CP.19. The UNFCCC operates the REDD+ Web Platform (mandated Decision 2/CP.13) to support country reporting.[^redd-warsaw-framework]
Readers encountering UNFCCC requirements in methodology or regulatory pages should distinguish: IPCC provides the scientific assessment layer and inventory guidelines; WMO and GCOS define Essential Climate Variables; CEOS/CGMS deliver the satellite data records; the UNFCCC Secretariat sets the treaty-level rules that make all of this necessary.
