While global climate negotiations are often defined by dramatic late-night bargaining and headline-grabbing outcomes at the annual UN Climate Conference (COP), much of the real architecture of climate governance is built in quieter negotiating halls.
The 64th sessions of the United Nations Framework Convention on Climate Change (UNFCCC) Subsidiary Bodies (SB64), taking place in Bonn from June 8 to 18, are emerging as a critical test of whether the world can translate past climate commitments into meaningful implementation.
Positioned between the landmark COP30 in Belém and COP31 scheduled for Antalya, SB64 comes at a defining moment for the global climate regime—particularly for climate-vulnerable countries like Bangladesh, where adaptation, finance, and climate justice remain urgent national priorities.
Why SB64 matters
Following the completion of the first Global Stocktake (GST-1) under the Paris Agreement, the focus of climate diplomacy is shifting from negotiations over frameworks to implementation. The GST delivered a sobering assessment: the world remains dangerously off track to limit warming to 1.5°C. It underscored the need to transition away from fossil fuels, triple renewable energy capacity, and double energy efficiency efforts globally.
At the same time, developing countries continue to raise concerns over climate finance. Although COP29 agreed on a new climate finance target of at least $300 billion annually by 2035, many vulnerable nations argue the figure falls far short of actual needs, estimated in the trillions.
For negotiators in Bonn, the challenge is turning unresolved issues from COP30—including adaptation finance, just transition, Article 9.1 obligations, and the Global Goal on Adaptation (GGA)—into workable pathways ahead of COP31.
Adaptation finance under scrutiny
Adaptation has emerged as one of the most politically sensitive agenda items at SB64.
International adaptation finance reached only $32 billion in 2024, significantly below the estimated annual requirement of $310–365 billion by 2030.
Negotiators are expected to discuss operationalizing the Baku Adaptation Roadmap and defining modalities for the Belém-Addis Vision task force, both seen as key to linking adaptation indicators with financial support.
Climate experts and vulnerable nations are also pushing developed countries to substantially increase public and grant-based adaptation finance over the coming decade.
Loss and damage concerns
The Fund for Responding to Loss and Damage (FRLD), once hailed as a major breakthrough, is also under growing scrutiny due to slow financial commitments. Following the conclusion of the Warsaw International Mechanism (WIM) review at COP30, loss and damage currently lacks a dedicated negotiating agenda item, raising concerns among vulnerable countries.
Negotiators in Bonn are expected to discuss institutional arrangements to ensure the issue remains central to climate governance, including mechanisms for assessing financial needs and non-economic losses.
Mitigation and NDC ambition
Another major focus is the Mitigation Work Programme (MWP), designed to scale up climate ambition during this decade.
Observers say the program has so far remained largely dialogue-driven, without sufficient policy outcomes.
At SB64, parties are expected to discuss stronger sectoral outcomes for hard-to-abate industries and clearer alignment between Nationally Determined Contributions (NDCs), Global Stocktake outcomes, and just transition strategies.
Just transition and carbon markets
The Belém-Antalya Mechanism (BAM) for Just Transition, launched at COP30, is likely to receive significant attention.
Delegates are expected to negotiate the framework’s structure, governance, and financing model to ensure meaningful participation from workers, Indigenous communities, and climate-vulnerable groups.
Meanwhile, negotiations under Article 6 carbon markets will focus on issues such as environmental integrity, baseline methodologies, and market oversight.
Trade and gender issues
SB64 will also host the first in a series of dialogues on trade and climate, following growing concerns among developing countries that climate-related trade standards could unfairly transfer decarbonization costs onto poorer economies.
Gender-responsive climate action is also expected to feature prominently under the newly adopted Belém Gender Action Plan, with discussions centering on integrating gender considerations into national climate policies and increasing funding for women-led climate initiatives.
“SB64 must deliver implementation pathways for adaptation, finance, and climate justice, especially for vulnerable countries like Bangladesh that are already facing escalating climate impacts,” said Md Shamsuddoha, chief executive of the Centre for Participatory Research and Development (CPRD).
For countries on the climate frontline, including Bangladesh, the success of Bonn will ultimately be measured not by diplomatic language but by whether negotiations lead to accessible finance, stronger adaptation systems, and tangible support for communities facing mounting climate risks.
