As COP31 opens in Antalya, the climate-finance agenda starts from a default that favours those who pay least. Mapping each major actor’s best alternative to a negotiated agreement shows why, and where the African Group of Negotiators should spend its limited bargaining capital.

Negotiation theory teaches that power sits with the party that can most comfortably walk away. In the language of the field, that party has the strongest BATNA. Namely, its best alternative to a negotiated agreement. Applied to the climate-finance agenda at COP31, the idea yields an uncomfortable conclusion. If Antalya produces nothing meaningful, developed countries lose very little, and the African Group of Negotiators (AGN) loses ground it may not recover.

This is because the no-deal outcome in Antalya is not a neutral midpoint. It is the compromise that developed countries already secured at COP30 in Belém. And the bargaining environment around that compromise is not standing still. It is eroding.

What ‘no deal’ would lock in

Antalya is not a fresh negotiation of the New Collective Quantified Goal (NCQG). At COP29 in Baku, Parties agreed on at least USD 300 billion a year by 2035, with developed countries ‘taking the lead’, alongside a much looser aspiration to scale finance from all public and private sources to USD 1.3 trillion. The NCQG deliberately allows outflows linked to multilateral development banks (MDBs) and mobilised private finance to be counted. It therefore already separates the legal language of developed-country leadership from an accounting architecture through which finance can be reported without matching public fiscal effort.

The Baku to Belém Roadmap does not repair that gap. It is a joint presidency initiative, not a negotiated decision. Its own report says it creates no new financing mechanism and labels 2026-28 contributions non-binding and non-exhaustive. Its indicative arithmetic for reaching USD 1.3 trillion assigns only USD 80 billion to bilateral concessional finance from developed countries and USD 40 billion to South-South cooperation, but USD 650 billion to cross-border private finance and USD 230 billion to ‘new sources’. If Antalya fails, five things stay as they are:

• The Paris Agreement obligation on developed countries to provide finance stays submerged in a diluted two-year work programme on Article 9 ‘as a whole’. Its agenda status and political weight remain unsettled after the June sessions in Bonn.
• Tripling adaptation finance remains a ‘call for efforts’ without a dollar amount, an enforceable trajectory or an agreed baseline. Even the decision text and post-COP analysis do not line up on the baseline and target year, a contested point that should be negotiated, not quietly assumed away.
• The roadmap remains a voluntary reference frame. Developed countries are urged to publish delivery plans by the end of 2026, but nothing specifies their content or the consequences of failing to do so.
• The Global Goal on Adaptation (GGA) remains without agreed text. Its deferral under Rule 16 at SB64 left the finance reference in brackets and the design of its taskforce unresolved.
• The Fund for Responding to Loss and Damage (FRLD), the Green Climate Fund (GCF) and the Global Environment Facility continue to rely on voluntary replenishment. The FRLD’s 2027 cycle and the GCF’s late-2027 pledging conference are institutional milestones, not Antalya commitments.

This default gives developed countries a high reservation value. A donor can accept thin language and retain discretion over quantum, instruments, channels, accounting, and timing. A recipient cannot turn an exhortation into fiscal space. The default also suits China: broad Article 9 language normalises voluntary flows from developing countries without converting them into an obligation. The only actors with a strong interest in moving the default are developing-country groups for which the quality of finance is a binding constraint.

Why finance is harder than trade

The asymmetry is structurally worse than on the companion trade agenda. On trade, the AGN at least faces identifiable regulatory counterparts, such as the European Union and the United Kingdom, with a revenue stream that could, in principle, be recycled and a market-access bargain that can be packaged with finance.

On climate finance, the largest historical contributor has left the room. The United States has withdrawn from the Paris Agreement, announced its withdrawal from the UNFCCC, rescinded its GCF commitments, and left the FRLD Board. The legal completion of UNFCCC withdrawal is expected around January 2027 and is contested over the form of notification. Operationally, however, the withdrawal is already in effect: the United States is dismantling the institutions and pledges through which it could be negotiated with.

The result is active erosion, not static under-provision. Roughly USD 4 billion in US GCF pledges has been rescinded. More than 98% of USAID climate-related awards have been terminated. US shareholder pressure contributed to the World Bank's decision to retire its 45% climate co-benefits target. The UK’s international climate finance has only about £6 billion of official development assistance (ODA) for 2026/27-2028/29, while European aid budgets contract. Faced with a demand for obligation, donors can now answer with fiscal constraint, MDB mobilisation or private-finance accounting.

Who can walk away

• The United States has the strongest BATNA, as an external shaper. It needs nothing from Antalya and can simply continue its exit, working instead through bilateral development and export finance, energy-security and critical-minerals diplomacy, its shareholder influence at the World Bank and IMF, and opposition to a shipping levy at the International Maritime Organisation. Its vulnerabilities are a Congress that may restore some foreign aid and a loss of international legitimacy.
• Russia has the cheapest walk-away. As an Annex I ‘economy in transition’, it carries no Annex II finance duty, and its rhetoric against Western unilateral measures aligns with the Global South rather than a contributor offer. Its outside options, such as the New Development Bank and nuclear export finance, provide no concessional finance to Africa.
• The European Union has a very strong inside BATNA. Namely, the European Investment Bank, Global Gateway, prospective EU budget resources, and carbon price revenue. But member-state ODA cuts and slow grant delivery weaken its credibility, and recycling carbon border revenue remains a candidate rather than a commitment.
• China’s BATNA is strong but commercial and geopolitical rather than contributor-side. Namely, clean-technology supply, the Belt and Road Initiative and the Forum on China-Africa Cooperation, multilateral banks it shapes, and its position as creditor. These flows are not grants and can aggravate debt vulnerability.
• The United Kingdom retains a moderate, DFI-centred alternative. Namely, British International Investment, export finance, MDB guarantees and re-channelled special drawing rights, but is constrained by its 0.3% ODA/GNI path, deep aid cuts and ministerial turnover.
• The AGN’s BATNA is the weakest, though improving. The African Credit Rating Agency, African Development Bank facilities, carbon markets, debt-for-climate operations and the leverage of an African-hosted COP32 are assets under construction. They cannot yet replace predictable concessional flows, while debt service and climate impacts are immediate.

The central crux is the contributor base. The EU and the UK want China and wealthy Gulf states to be treated as indispensable contributors to a broad USD 1.3 trillion architecture. China insists on the 1992 Annex distinction and on the voluntary character of South-South cooperation. This standoff does not open a route to more grant finance for Africa. It creates a mutual-excuse structure. The EU can defer a stronger Article 9.1 architecture until ‘all actors’ share the burden; China can defend not paying by pointing to obligations developed countries have not met. Both preserve their BATNAs. The AGN bears the cost of a work programme that debates who should pay, yet no one is compelled to do so.

What Africa can realistically win

There is no plausible zone of possible agreement in Antalya on a binding Article 9.1 quantum, on reopening the USD 300 billion figure, on compulsory expansion of the contributor base, or on compensation. The credible landing zone is qualitative, procedural, and access oriented. African negotiators, who have long pressed for grant-based and highly concessional finance, should push to:

• clarify the adaptation-finance baseline and target year;
• require reporting on grant-equivalence and concessionality;
• adopt GGA indicators with a Party-driven implementation pathway;
• establish FRLD replenishment modalities and simplified access;
• advance MDB reform on the cost of capital, access and callable capital;
• connect debt relief to climate investment;
• earmark revenue from voluntary levies; and
• establish transparency on Article 9.1 delivery.

None of these will make headlines. But accounting rules, access criteria, and reporting duties are where legal commitments either acquire content or quietly lose it. The AGN should package the finance work programme, the GGA and adaptation, and the trade track together. Importantly, the AGN should refuse to spend scarce capital on declaratory victories that leave the accounting and access architecture unchanged. In Antalya, the prize is not a bigger number. It is a finance architecture in which the existing numbers mean something.
