Why SB64 Matters?
The 64th Sessions of the UNFCCC Subsidiary Bodies (SB64), taking place in Bonn from 8-18 June 2026, represent the first formal climate negotiations since COP30 in Belém and the primary opportunity for Parties to advance technical work before COP31 in Antalya. While Bonn is not expected to produce major political decisions, it will play a critical role in determining whether Parties can rebuild trust, advance implementation, and maintain momentum across key areas, including adaptation finance, loss and damage, just transition, trade, and food systems.
SB64 also arrives at a moment of growing geopolitical uncertainty, increasing climate impacts, and mounting pressure on governments to demonstrate that international climate commitments are translating into real-world action. For Africa and other developing regions, the Bonn session will provide important signals on the future direction of climate finance, adaptation support, and the broader implementation of the Paris Agreement.
Adaptation
Can Adaptation Move from Frameworks to Implementation?
Adaptation remains one of the most politically significant issues at SB64. Following the adoption of the Belém Adaptation Indicators and the launch of the Belém–Addis Vision at COP30, negotiators now face the challenge of translating technical frameworks into practical support and measurable resilience outcomes. Discussions in Bonn are expected to focus on adaptation indicators, National Adaptation Plans (NAPs), adaptation finance, and the broader architecture supporting implementation. For vulnerable countries, particularly in Africa, the key question is whether adaptation can move beyond reporting and measurement toward delivering tangible resilience benefits on the ground.
Climate Finance
Can Climate Finance Move from Promises to Delivery?
Climate finance remains the foundation upon which implementation depends. While recent COP outcomes have produced new finance commitments and roadmaps, questions remain about accessibility, predictability, and scale.
Discussions at SB64 will provide an early indication of how Parties intend to operationalize the New Collective Quantified Goal (NCQG) and broader efforts to mobilize climate finance. Particular attention will focus on adaptation finance, implementation pathways, and efforts to improve access for developing countries. For many observers, the credibility of the climate regime increasingly depends on whether financial commitments begin translating into real-world support.
Loss and Damage
Is Loss and Damage Entering an Implementation Phase?
With the operationalization of the Fund for Responding to Loss and Damage underway, attention is increasingly shifting from institutional design to delivery. Bonn will provide an opportunity to assess progress on resource mobilization, governance arrangements, and broader efforts to strengthen the loss and damage architecture.
Discussions will also contribute to ongoing work under the Warsaw International Mechanism and emerging efforts to improve methodologies for assessing climate-related losses. For many developing countries, the central question is whether support mechanisms can respond at the scale required by growing climate impacts.
Just Transition
What Does a Just Transition Mechanism Actually Look Like?
Following decisions taken at COP30, discussions on just transition are expected to enter a more operational phase. Negotiators will begin exploring how the newly agreed mechanism can support countries, workers, and communities navigating economic transformation.
Key debates are likely to focus on governance, participation, capacity-building, and implementation support. For developing countries, including many across Africa, just transition discussions remain closely linked to broader questions of industrialization, employment, energy access, and sustainable development.
Trade and Climate
How Will Trade and Climate Interact in the Coming Decade?
Trade is emerging as one of the most important and politically sensitive frontiers of climate governance. New dialogues launched after COP30 will begin exploring how climate and trade policies interact, particularly in relation to carbon border adjustment measures, industrial policy, competitiveness, and international cooperation.
The outcome of these discussions could have significant implications for developing economies seeking to industrialize while also responding to climate challenges. For Africa, the debate increasingly centres on whether climate-related trade measures will create new barriers or new opportunities for economic transformation.
Action for Climate Empowerment (ACE)
Can Action for Climate Empowerment Move Beyond Awareness-Raising?
The midterm review of the Glasgow Work Programme on Action for Climate Empowerment presents an important opportunity to strengthen one of the key enablers of climate action. ACE connects climate policy to education, training, public participation, public awareness, and access to information.
Discussions at SB64 are expected to explore implementation gaps, support needs, and the future direction of the ACE agenda. For youth and civil society actors, the process will help determine whether ACE evolves into a stronger implementation framework capable of supporting whole-of-society climate action.
The Youth Print Assessment
SB64 is unlikely to produce headline political outcomes. Its significance lies in whether Parties can establish the technical foundations, political trust, and implementation pathways necessary for meaningful progress towards COP31 and the broader goals of the Paris Agreement.
For Africa, the session will be particularly important in determining whether adaptation, finance, loss and damage, and just transition receive the political attention and practical support required to address the continent's growing climate challenges.
As the climate regime increasingly shifts from negotiation to implementation, Bonn will provide an important test of whether multilateral climate cooperation can deliver at the scale and speed required in the years ahead.
