The 2025 Bonn Climate Conference advanced the consideration of arrangements for the transition of the Adaptation Fund to exclusively serve the Paris Agreement on climate change. Delegates also settled on guidance for refining the list of indicators to measure progress toward the Global Goal on Adaptation (GGA).

According to the Earth Negotiations Bulletin (ENB) summary report of the meeting, “[p]art of that compromise was a reference to ‘indicators for means of implementation to measure: access, quality, and adaptation finance, including provision,’ a key priority for developing countries to close the widening adaptation finance gap.”

The Bonn Conference was the first time parties to the UNFCCC convened since the 2024 Baku Climate Change Conference adopted the new collective quantified goal on climate finance (NCQG). “The widespread disappointment among developing countries with that outcome cast its shadow over the June Subsidiary Bodies’ meetings,” ENB writes. It took parties almost two days to adopt the agendas due to a proposal by the Like-Minded Developing Countries (LMDCs) to include in the discussions the implementation of developed countries’ climate finance obligations and trade-restrictive unilateral measures. “Although this impasse was eventually resolved, it set the tone for the negotiations to come,” ENB reports, during which “parties repeatedly clashed over the provision of means of implementation,” encompassing finance, technology transfer, and capacity building.

On science, following two weeks of difficult negotiations, delegates were able to find agreement to “take note” of the World Meteorological Organization’s (WMO) ‘State of the Global Climate 2024’ and ‘Global Annual to Decadal Climate Update 2025-2029’ reports and the multi-decadal estimates of current global warming of between 1.34 and 1.41°C. No agreement was reached on the technology implementation programme, with views diverging on its contribution to implementing the decision on the first Global Stocktake (GST) under the Paris Agreement, especially with regards to energy transition.

On many issues, parties captured progress made in Bonn to serve as a basis for further negotiation at their next meeting in Belém, Brazil, in November 2025. “These documents have varying degrees of maturity,” ENB notes, “with some merely compiling proposals, while others already indicate potential landing zones.”

According to the ENB analysis of the meeting, incoming “Presidency-led consultations on the development of the roadmap to USD 1.3 trillion in climate finance, which is supposed to be presented in Belém, gave little assurance that it will produce the actionable measures that many expect.”

The 2025 Bonn Climate Conference convened from 16-26 June 2025 in Bonn, Germany. It included the 62nd meetings of the Subsidiary Body for Implementation (SBI) and the Subsidiary Body for Scientific and Technological Advice (SBSTA), mandated events, and side events.
