COP31 2026 — Istanbul
COP31 is the annual UN Climate Change Conference (Conference of the Parties to the UNFCCC), held in Istanbul for the first time. Hosted by Turkey — a nation bridging Europe and the Middle East, with significant fossil fuel use but rapidly expanding renewables — COP31 takes place against the backdrop of the first NDC cycle fully aligned with the 1.5°C pathway. The conference will assess whether countries' updated climate pledges are on track to limit warming to 1.5°C, and advance implementation of the landmark COP28 "transition away from fossil fuels" language.

COP31 key agenda themes
| Agenda item | Status / key question |
|---|---|
| NDC assessment | Are 2025-submitted NDCs collectively aligned with 1.5°C? Global stocktake follow-up |
| Fossil fuel phase-out implementation | Translating COP28 "transition away" language into country-level commitments and timelines |
| Climate finance (NCQG) | Operationalising the post-2025 climate finance goal; developed country contributions |
| Article 6 carbon markets | Article 6.2 bilateral mechanisms; 6.4 Paris Agreement Crediting Mechanism implementation |
| Loss and damage fund | Capitalisation and governance of the new Loss and Damage fund; first disbursements |
| Fossil fuel subsidy reform | Country reporting on subsidy phase-out progress; IMF/World Bank subsidy reform support |
| Just Transition | Coal transition financing; developing economy support for phasing out fossil fuels fairly |
Fossil fuel phase-out: the COP28 legacy
COP28 (Dubai, 2023) marked the first time the UNFCCC process explicitly mentioned "fossil fuels" — language calling for a "transition away from fossil fuels in energy systems" by 2050. COP31 is the first major COP where implementation of this language becomes a live accountability issue:
- Major oil producers (Saudi Arabia, Russia, Iran) will face scrutiny of their NDC ambition vs their production plans
- Major fossil fuel consumers (India, China, USA, EU) will report on coal, oil, and gas demand reduction progress
- The IEA's tracking of COP28 pledges (triple renewables, double efficiency by 2030) provides an early scorecard
Fossil fuel subsidy reform at COP31
Fossil fuel subsidies are increasingly central to COP discussions because they directly undermine the energy transition:
- Global fossil fuel subsidies (explicit + implicit/tax expenditure basis) exceeded $7 trillion in 2022 (IMF estimate) — primarily through suppressed fuel prices in oil-producing and developing nations
- Countries with large fuel subsidies (Iran, Saudi Arabia, Venezuela, Nigeria, Indonesia) face COP pressure to show phase-out timelines
- The IMF and World Bank support country-specific subsidy reform roadmaps, including social protection measures for vulnerable households
For country-specific subsidy reform analysis, see our Nigeria subsidy removal, Indonesia fuel subsidies, and Middle East subsidy reform. For the subsidy concept, see our fuel subsidy glossary entry.
What COP31 outcomes mean for fuel markets
COP31's outcomes will signal whether the world is on a credible 1.5°C path — which, in the IEA's modelling, requires oil demand to peak by 2030 and fall rapidly thereafter. If COP31 produces strong NDCs with concrete EV mandates, carbon pricing commitments, and subsidy phase-out schedules, long-run oil demand expectations will shift downward — potentially reducing investment in new upstream capacity and setting up a supply-constrained market in the 2030s. If COP31 produces weak outcomes, the "high fossil demand" scenario becomes more likely, with higher long-run prices but also higher climate risk.

Frequently asked questions
-
Where and when is COP31?
- COP31 takes place 9–20 November 2026 in Istanbul, Turkey. Turkey hosts as a nation bridging Europe and the Middle East, with significant renewables expansion and EU accession candidacy. COP31 follows COP30 (Belém, Brazil, 2025) and is the first COP to assess NDCs submitted under the new 1.5°C-aligned cycle.
-
What are the key agenda items for COP31 2026?
- Key COP31 agenda: assessing whether 2025 NDCs are on a 1.5°C path; implementing COP28 "transition away from fossil fuels" language; climate finance (NCQG); Article 6 carbon market implementation; Loss and Damage fund operationalisation; fossil fuel subsidy phase-out progress; and just transition support for fossil-fuel-dependent developing economies.
-
How does COP31 affect oil demand and fuel prices?
- COP decisions shape long-run fuel demand through EV mandates, carbon pricing, and subsidy reform commitments. Near-term pump prices are not directly set by COP. Over a 5–15 year horizon, strong COP outcomes (ambitious NDCs, subsidy phase-outs, carbon pricing expansion) reduce oil demand growth — eventually weighing on long-run crude prices. Weak outcomes support higher long-run demand and prices.
