UNFCCC's SB64 page records the June Climate Meetings closing in Bonn on 18 June. In his closing statement, UNFCCC executive secretary Simon Stiell said there were still significant divides and substantial work for the intersessional period ahead. He credited parties with steps on a just transition mechanism and the review of the just transition work programme, but said the talks had not delivered on adaptation and mitigation despite broad agreement that action must deepen and accelerate.
Carbon Brief's account of the talks described few tangible outcomes after two weeks of gridlock. It reported that negotiators failed to find agreement in several areas, including scaling up global emissions cuts and funding for climate adaptation. Climate Home News reported similar splits between developed and developing countries over finance and science.
Table: Selected Bonn negotiation tracks
| Track | Bonn outcome | Next pressure point |
|---|---|---|
| Just transition | UNFCCC said parties took steps toward a mechanism and work-programme review | Texts and decisions prepared for COP31 |
| Adaptation | Stiell said parties did not deliver in Bonn | Finance and implementation demands continue into the intersessional period |
| Mitigation | Stiell said parties did not deliver in Bonn | COP31 must test whether emissions-cutting commitments become stronger decisions |
| Existing obligations | Stiell warned against reopening prior decisions or backsliding | Parties face pressure to preserve Paris Agreement commitments |

The just-transition movement is not trivial. In UN language, it concerns how economies shift away from high-emitting activity while protecting workers and communities. For countries dependent on fossil fuels, energy-intensive industry or climate-vulnerable jobs, the design of that mechanism affects whether decarbonisation is politically durable as well as technically possible.
