Negotiations on cooperation with other international organizations at the United Nations Framework Convention on Climate Change (UNFCCC) 31st Conference of Parties (COP31) in November come at a time of growing recognition that climate change, biodiversity loss, and land degradation are deeply interconnected and cannot be addressed effectively through fragmented international processes. There is a need for a more coherent and coordinated approaches to implementation across the Rio Conventions—the UNFCCC, Convention on Biological Diversity (CBD), and the UN Convention to Combat Desertificiation (UNCCD)—and other multilateral environmental agreements (MEAs).
2026 presents a political opportunity to move the debate forward. This “triple COP” year for the three Rio Conventions coincides with wider efforts to deliver on the Sustainable Development Goals (SDGs) and advance consideration of what a post-2030 development framework could look like—including through the UN Expert Group on Climate-SDG Synergies.1Expert Group on Climate and Sustainbale Development Goals (SDG) Synergies, Synergy Solutions for a World in Crisis: Tackling Climate and SDG Action Together (UNFCCC and UNDESA, 2023), https://sdgs.un.org/synergy-solutions-world-crisis-tackling-climate-and-sdg-action-together. It also overlaps with ongoing discussions under the UN’s system-wide reform plan (the UN80 Initiative). Specifically, it connects to UN80’s “Work Package 27” (WP27) on environment.2UN80 Initiative, “Environment: Progress and Next Steps,” https://un80actions.un.org/data/progress/wp27.pdf (Advance Copy). Together, these processes need to effectively respond to calls for stronger international cooperation and more integrated implementation approaches.
While support for a synergistic approach to climate action is growing, institutional fragmentation remains a significant challenge and initial findings under WP27 have identified the Rio Conventions as a particular opportunity for improved coherence. Countries continue to navigate overlapping reporting requirements, separate workstreams, and parallel implementation processes across conventions that often pursue related objectives. For many developing countries and smaller delegations, these duplications create administrative burdens that strain already limited technical and financial capacities.
There is already a basis for stronger cooperation between the UNFCCC and other MEAs. Given the wider context of reforms under UN80 and widespread budget cuts, there may value in further enhancing policy coherence and cooperation across convesions. Parties could push for further cooperation while still respecting the distinct legal mandates, governance arrangements, and decision-making aurthority of each Convention, and while fitting within existing resources If there is political will, the discussions at COP31 could provide an opportunity to move beyond general calls for enhanced coordination toward more practical cooperation, such as reducing reporting burdens for countries across Conventions and strengthening existing cooperative activities through the Joint Liaison Group of Rio Convention Secretariats (JLG) and across UNFCCC workstreams.
13. Parties to all three Rio Conventions and other MEAs have acknowledged that climate change, biodiversity loss, and land degradation are interconnected and should be addressed in a more coordinated manner.
14.The conversations under the UNFCCC are unfolding against three important backdrops that could create conditions outside of the UNFCCC to further strengthen cooperation on climate among MEAs:
15. Member States at UNEA-6 (2023) adopted a resolution on promoting synergies, cooperation or collaboration for national implementation of MEAs and other relevant environmental instruments that encouraged Member States to enhance synergies among MEAs and highlighted the importance of climate-SDG synergies.4UN Environment Programme (UNEP), Resolution on promiting synergies, cooperation or collaboration for national implementation of multilateral environmental agreements and other relevant environmental instruments, UNEP/EA.6/L.7 (February 28, 2024), https://docs.un.org/en/UNEP/EA.6/L.7. At CBD COP16 (2024), Parties welcomed the GST’s calls for strengthened Rio synergies.5Convention on Biological Diversity (CBD), Biodiversity and climate change, Decision 16/22 (November 1, 2024), https://www.cbd.int/doc/decisions/cop-16/cop-16-dec-22-en.pdf. At UNCCD COP16 (2024), Parties adopted a decision encouraging enhanced collaboration across conventions.6UNCCD, Promotion and strengthening of relationship with other relevant conventions and international organizations, Decision 8/COP.16 (December 14, 2024), https://www.unccd.int/sites/default/files/2025-03/8-cop16.pdf. Further negotiations on synergies are expected across both for a this year.7UN Convention on Combatting Desertification (UNCCD) COP17, Provisional agenda with annotations, ICCD/COP(17)/1, Agenda Item 4 (April 17, 2026), https://www.unccd.int/sites/default/files/2026-04/cop1-advance.pdf (Advance copy); CBD COP17, Provisional agenda, CBD/COP/17/Rev.1, Agenda Item 13 (March 16, 2026), https://www.cbd.int/doc/c/8344/fbc9/280c8fa06e317bd6aafec8ad/cop-17-01-rev1-en.pdf.
16. However, despite growing recognition of the need for synergistic approaches and initiatives to increase synergies, implementation and institutional processes often remain fragmented. Countries continue to navigate overlapping reporting requirements, separate workstreams, and parallel initiatives across conventions that frequently pursue related objectives. WP27 has also identified that the Rio Conventions, in particular, are frequently undertaking similar workstreams—including on implementation support, capacity building, and reporting—through separate institutional processes.8UNEP, “Working Group 27 Briefing,” April 23, 2026.
17. For many lower capacity countries, this fragmentation creates unnecessary burdens. Reporting obligations are a particular challenge, especially where conventions request overlapping information through different timelines and formats. This fragmentation can undermine effective delivery of the Paris Agreement by increasing transaction costs and stretching limited national capacities.
18. Developing voluntary tools or platforms that help countries streamline reporting processes across conventions could be one practical focus for future work. A targeted technical support mechanism, similar to one modeled by the Paris Agreement’s Capacity Building Initiative for Transparency, could help align reporting efforts while respecting the distinct legal mandates of each agreement and support more integrated national implementation strategies. At the same time, institutional requirements under reporting regimes should aim to improve coherence and avoid duplication, for example, by identifying overlapping reporting requirements with respect to the enhanced transparency framework guidelines and SDG delivery indicators.
19. Panama’s NDC 3.0 could be highlighted as an example of streamlining overlapping reporting requirements across conventions. It submitted one document to all three Rio Conventions, serving as nationally determined contribution (NDC) and national adaptation plans (NAP) to the UNFCCC, its national biodiversity strategy and action plan (NBSAP) to the CBD, and its land degredation neutrality (LDN) target to the UNCCD.9Panama Ministerio de Ambiente, Pacto de Panamà con la Naturaleza (2025), https://unfccc.int/sites/default/files/2025-11/Pacto%20de%20Panam%C3%A1%20con%20la%20Naturaleza%20%28Nature%20Pledge%29.pdf.
20. Initial findings under UN80’s WP27 show fragmentation and opportunities for stronger coordination. A more complete analysis and mapping of coordination and implementation across MEAs is expected in June for presentation to the Secretary-General. The findings will be reflected in an information brief to be made available by September 2026.10UN80 Initiative, “Environment: Progress and Next Steps.” The value of stronger cooperation will ultimately be determined not by whether new coordination mechanisms exist, but by whether they make implementation more effective and less burdensome for Parties.
21.As Parties work to meet their climate, biodiversity, land restoration, and sustainable development commitments—often under significant financial and technical constraints—greater alignment among international organizations and the UNFCCC may be needed. The discussions at COP31 may help clarify how the UNFCCC can best contribute to wider coherence efforts underway across the UN system, including through the UN80 initiative and broader SDG implementation discussions, while fully respecting the mandates and governing bodies of other conventions and organizations.
22. The UN expert group on climate and SDG synergies, co-convened by the UN Department of Economic and Social Affairs (UN DESA) and the UNFCCC secretariat, has developed recommendations on how to simultaneously achieve the SDGs and tackle climate change, recognizing the importance of synergies in confronting interconnected challenges. In order to avoid the worst climate impacts, SDGs including poverty, inequality, hunger, food security, deforestation, and energy access must be at the heart of 1.5 degree C transition pathways. With 80 percent of SDG targets directly linked to climate change, acting on climate and human development together can deliver close to 40% greate efficiency in government spending.11UN Expert Group on SDG Climate Synergies, Harnessing Climate and SDG Synergy Quantifying the Benefits: Third Global Report on Climate and SDG Synergies (UN DESA and UNFCCC, 2025), https://sdgs.un.org/sites/default/files/2025-11/2025%20UN%20Synergy%20Solutions%20coversFinal-111125.pdf.
23. This was further supported by the 2024 High Level Political Forum (HLPF) Political Declaration, which stated “we commit to enhance synergies towards effective national climate and development policies and actions, contributing to the achievement of global climate goals and delivering on the 2030 Agenda.”
24. Parties diverge on what they see as an appropriate scope for future work under the agenda item on cooperation with other international organizations. There is no consensus on what work under the agenda item should encompass going forward. Parties emphasized that work must be undertaken with respect to the decision-making authority of distinct Conventions, and within existing mandates and resources.
25. The information note by the Secretariat on cooperative activities suggests that the SBSTA consider:1UNFCCC, Summary of cooperative activities with United Nations entities and other international orgnizations that contribute to the work under the Convention.
26. While several Parties expressed interest in working to improve the function of the JLG, tensions over procedural considerations and a lack of common understanding of what Parties could feasibly do to strengthen the JLG through SB conclusions or a COP decision slowed progress at SB64.
27. Some Parties are wary that further work under the agenda item could create duplicative processes and increase burdens on countries. Further, some Parties raised concerns that since the COP cannot mandate work by the JLG, discussions about what the group could do to improve cooperation may be futile. It is important to not that while the COP cannot mandate activities by the JLG, it can invite or urge the JLG to undertake activities—and has done so in the past. The COP could also invite or urge the Secretariat or Executive Secretary to undertake activities to improve cooperation with other international organizations.
28. Some Parties expressed a desire to improve synergistic approaches through this agenda item, while others expressed concerns with the term “synergies.” When the UNFCCC initially formally recognized the JLG in decision 13/CP.8, it did so in the context of “promoting synergies under the common objective of sustainable development.”
29. Any future work should seek to balance improved coordination and coherence with respect to the distinct legal mandates, governance arragements, and decision-making authority of each Convention, while fitting within existing resources.
30. If Parties were to decide that there was sufficient political will, several decision elements are possible without changing existing mandates, resources, and governance arrangements. One potential way forward could be to ask the UNFCCC Secretariat, in consultation with other Secretariats, to make suggestions on what could be done within the above restrictions.
31. Greater attention could be given to JLG of the Rio Convention Secretariats. The current “triple COP” year presents an opportunity to strengthen both the transparency and practical role of the JLG in supporting coordinated implementation. Parties could consider encouraging more regular engagement between Secretariats and clearer communication in ongoing collaborative work.
32. While Parties cannot mandate activities by the JLG in a COP decision, they could invite or urge the JLG, in a manner that is consistent with the Conventions’ respective mandates, governance arrangements, and existing resources, to engage in a range of activities including:
33. Parties also have the ability to request the UNFCCC Secretariat to undertake activities to strengthen cooperation with other international organizations, recalling Article 8.2(e) under the Convention. This could include:
34. Existing mandates under the UNFCCC also provide useful entry points to improve synergies with other international organizations. For example, under the Belém Gender Action Plan, Activity C.4 calls for strengthening cooperation among subsidiary bodies, relevant UN entities, and the JLG to support gender responsive action.
35. The CBD proposal for a multi-level roadmap supporting implementation across the Rio Conventions could also help inform discussions.2CBD, Recommendation adopted by the Subsidiary Body for Scientific, Technical, and Technological Advice on 23 October 2025: Biodiversity and Climate Change, CBD/SBSTTA/A/REC/27/3 (October 24, 2025), https://www.cbd.int/doc/recommendations/sbstta-27/sbstta-27-rec-03-en.pdf.
36. Parties will need to determine whether and how work on this agenda item should continue beyond 2026. Options could inter alia include:
37. With regard to the frequency of discussions under the SBSTA agenda item on cooperation with other international organizations, options include
38. If Parties were to agree to continue consideration at future sessions, such discussions could:
39. Parties could consider:
40. In considering options to strengthen cooperation with international organizations under the UNFCCC, Parties may also wish to note parallel opportunities available under the other Rio Conventions.
41. The provisional agenda for UNCCD COP17 in Ulaanbaatar (August 2026) includes a dedicated item on “Promotion and strengthening of relationships with other relevant conventions and international organizations, institutions and agencies.”1UNCCD, Provisional agenda and annotations. This agenda item provides a direct mandate for Parties to consider measures relating to cooperation and coordination with international organizations and other multilateral processes.
42. Recent UNCCD decisions further underscore the importance of coordinated action across the Rio Convention agendas. Decisions 7/COP.16 and 8/COP.16 encourage Parties to adopt holistic and integrated approaches to addressing desertification, land degradation, and drought, while recognizing their links with climate change and biodiversity loss and promoting the scaling up of nature-based solutions and ecosystem-based approaches.2UNCCD, Enhancing implementation of the Convention and the 2018-2030 Strategic Framework of the United Nations Covention to Combat Desertification, Decision 7/COP.16, ¶ 13 (December 14, 2024) , https://www.unccd.int/sites/default/files/2025-03/7-cop16.pdf; UNCCD, Promotion and strengthening of relationships with other relevant conventaions and international organizations, instutions and agencies, Decision 8/COP.16 (December 14, 2024), https://www.unccd.int/sites/default/files/2025-03/8-cop16.pdf.
43. Parties to the CBD are also expected to discuss cooperation with other Rio Conventions. Under CBD Decision 16/22 on biodiversity and climate change, Parties initiated work on enhancing coherence and cooperation across the Rio Conventions, including consideration of a possible joint work programme.3CBD, Biodiversity and Climate Change, Decision 16/22 (November 1, 2024) , https://www.cbd.int/decisions/cop?m=cop-16. SBSTTA Recommendation 27/3 builds on this mandate by inviting the Convention secretariats and Presidencies to develop a multilevel roadmap and accompanying mapping study to identify concrete opportunities for enhanced cooperation and synergies at the short-, medium-, and long-term horizons.4CBD, SBSTTA Recommendation 27/3 (October 24, 2025) , https://www.cbd.int/recommendations/sbstta?m=sbstta-27. Discussions at this year’s CBD COP17 in Yerevan (October 2026) are expected to build on these recommendations.
44. Many Parties are members of all three Conventions and may therefore pursue complementary approaches across forums to reinforce coherence, reduce duplication, and support integrated implementation at national and international levels.
