COP31 issues an implementation path or timetable for transitioning away from fossil fuels by 20 November 2026.
Antalya talks are debating next steps for moving away from fossil fuels. Success requires concrete timelines or roadmaps in the final summit text.
Across 6 frontier models answering independently, the panel thinks this is unlikely: the median is 16%.
They broadly agree, 25 points between GPT at 37% and Claude at 12%.
Nothing is settled until 11 Dec 2026, when the outcome is checked against sources and every number above gets a permanent score.

It turns on whether major producers accept dated language rather than another voluntary, nationally determined process.
- COP28’s 2023 text called for a transition away but set no timetable, and subsequent COP outcomes have avoided binding phaseout dates.
- A COP31 decision needs consensus by 20 November; Saudi Arabia and other producer states can block explicit fossil-fuel timelines.
- Odds rise sharply if the host and EU secure a pre-COP bargain pairing a roadmap with finance and flexibility for developing countries.

COP31 must convert Antalya's fossil-fuel debate into dated text within days, against a consensus rule and a year of stalled follow-through.
- COP28's 2023 'transition away' language was never operationalized; COP29 and this year's Bonn sessions produced no timetable, so the base rate for dated paths is near…
- Antalya runs 9-20 November 2026, so the final text lands essentially at the resolution deadline, leaving no room for a late rescue.
- Petrostates and the consensus rule can strip dates to 'pathways'; the tell would be a pre-conference draft with bracketed years, which has not appeared.

COP consensus on any fossil-fuel timetable still requires petrostate buy-in that has never materialized.
- Turkey as host must produce a text all 190+ parties accept by ~20 Nov; Saudi/Russia/OPEC+ have blocked dates at every COP since Dubai.
- No COP has ever attached a timetable or implementation path to the 2023 “transitioning away” language; finance and NDCs remain the usual substitutes.
- A last-minute EU-China-US joint demand plus Turkish pressure could flip it, but current Antalya drafts show only process language.

Consensus rules let petrostates easily veto explicit phase-out timetables or binding sectoral implementation pathways.
- UNFCCC consensus allows major producers like Saudi Arabia and Russia to dilute roadmaps into voluntary, unquantified pledges.
- COP28 took days of overtime just to mention 'transitioning away', and subsequent COPs have consistently avoided hard timelines.
- A major shift in G20 petrostate alignment or a radical overhaul of UNFCCC consensus decision rules would be required to pass this.

Consensus rule plus fossil-fuel-producer veto makes any concrete timetable historically unprecedented at COPs.
- No COP in 30 years has produced a binding fossil-fuel transition timetable; COP28's 'transitioning away' language was the ceiling after Saudi Arabia and others blocked…
- Turkey as host may push for a legacy outcome, but consensus decision-making means a single objection from Riyadh, Moscow, or Baghdad can strip concrete timelines from…
- A shift to qualified majority voting or a major geopolitical rupture among OPEC+ members would be needed to move this above 30%.

Hinges on whether COP31 (Antalya) final text sets binding timelines, which COP summits almost never deliver.
- COP28/29/30 history shows consensus texts favor vague 'transition away' language over concrete timetables due to oil-state veto power.
- Multiple major fossil-fuel producers (Saudi Arabia, Russia, others) must agree, and they've blocked timeline language at every prior COP.
- A surprise coalition push or EU/small-island bloc breakthrough before Nov 20 2026 is the main thing that could flip this toward yes.
