Bonn climate talks: Key outcomes from the June 2026 UN climate conference
Why this matters: environmental and climate reporting with long-term consequences.
Two weeks of tense UN climate talks in Bonn, Germany, have produced few tangible outcomes as diplomats faced “gridlock”. Negotiators failed to find agreement in numerous areas, such as scaling up global emissions cuts and funding for climate adaptation. In the closing plenary, many diplomats lamented weakened trust in the UN climate process, as it struggled to find its footing in a new geopolitical landscape. As ever, climate finance was one of the greatest sources of tension between developed and developing countries, influencing the debate around adaptation and trade in the Bonn talks. Many countries criticised “coordinated attacks” on science by those with “fossil-fuel interests”. Some delegates saw progress on a “just transition mechanism” to support communities through decarbonisation as a positive outcome, with a package of texts agreed for the COP31 climate summit in Antalya, Turkey. Reporting from the talks in Bonn, Carbon Brief covers the key outcomes and disputes at the 64th biannual sessions of the UN Framework Convention on Climate Change (UNFCCC) subsidiary bodies (SB64).

In particular, parties were unable to agree on text relating to the “global goal on adaptation” (GGA). Across the two weeks, progress was “stuck, stalled or deferred”, even in the rooms of technical adaptation items, Jeffrey Qi, policy advisor with International Institute for Sustainable Development’s (IISD) resilience program, told Carbon Brief. In many of the rooms, this was due to a “fault line” over finance, Ana Mulio Alvarez, policy advisor at thinktank E3G told Carbon Brief, as developing countries sought support to help protect themselves from escalating climate hazards.
