'The World Is Bigger Than Five': Türkiye's UN Security Council Reform Case and COP31 Climate Diplomacy

Why It Matters

The doctrine 'The world is bigger than five' argues that the UN Security Council, which holds primary responsibility for international peace and security under the UN Charter, should be more representative, accountable and effective, because five states set its agenda and can block any substantive decision with a veto. Türkiye pairs this institutional case with a second track in global governance: the Zero Waste initiative and the hosting of the COP31 climate conference. Together they show how Ankara frames multilateralism as a question of fairness, not only of power.

Reform remains stalled, mainly because reformers disagree among themselves about whether to add permanent seats, and because any Charter amendment needs the consent of all five permanent members. Understanding who wants what is the key to judging whether change is realistic.

Background

How the Council is built

The Council's structure comes from the 1945 UN Charter. Article 23 names five permanent members, and Article 27(3) gives each the power to block non-procedural decisions. The Council was enlarged once, from 11 to 15 members, through an amendment to Article 23 that entered into force in 1965. The ten elected seats are distributed by regional groups, and members serve two-year terms.

Amending the Charter is deliberately difficult. Under Article 108, an amendment needs a two-thirds vote in the General Assembly and ratification by two-thirds of UN members, including all five permanent members. Each of the five therefore holds an effective veto over reform of the veto itself.

Chronology of the reform debate

The IGN process focuses on five negotiating clusters: categories of membership, regional representation, the size of an enlarged Council and its working methods, the Council's relationship with the General Assembly, and the veto. After more than fifteen years, there is no consolidated negotiating text that all sides accept.

Climate and the Council

The link between the two topics is practical. In December 2021 a draft Council resolution on climate and security, drafted by Ireland and Niger, failed after Russia vetoed it and India voted against. The episode is often cited as an example of how Council politics can limit action on global challenges that most members want to address. Climate governance itself runs mainly through the UNFCCC process and its annual Conference of the Parties (COP), where decisions are taken by consensus among parties rather than by a small group of states.

Key Players & Positions

The permanent five

• United States: In September 2024 Ambassador Linda Thomas-Greenfield announced US support for two permanent seats for African states and one rotating seat for small island developing states, while saying new permanent members should not receive an expanded veto. Washington has previously backed permanent seats for several large states.
• United Kingdom and France: Both say they support expansion in both permanent and non-permanent categories, including permanent seats for Brazil, Germany, India and Japan and a stronger African presence. France has also promoted voluntary veto restraint in mass atrocity situations.
• Russia and China: Both publicly support giving developing countries, especially African states, a larger voice, and Russia has voiced support for the aspirations of India and Brazil. Both resist changes that would dilute the veto and generally insist on a broad, consensus-based process.

Reform groupings

• G4 (Brazil, Germany, India, Japan): Seek permanent seats for themselves and an expanded Council in both categories.
• L.69 group: A bloc of developing countries from Africa, Latin America and the Caribbean, and Asia-Pacific, named after a 2007 draft document. It supports expansion in both categories and stronger representation of the Global South.
• African Group: Under the Ezulwini Consensus and Sirte Declaration, it seeks at least two permanent seats with all prerogatives, including the veto, and five non-permanent seats.
• Uniting for Consensus (UfC): Led by Italy and Pakistan, with members including Argentina, Canada, Colombia, Costa Rica, Malta, Mexico, the Republic of Korea, San Marino, Spain and Türkiye. It opposes new permanent seats and proposes a new category of longer-term elected seats, with the possibility of immediate re-election, within a Council in the mid-twenties in size.
• ACT group: A cross-regional group of states focused on accountability, coherence and transparency in Council working methods, including veto restraint.

The deepest divide is therefore not between 'reformers' and 'opponents', but between those who want new permanent members and those who see that as entrenching a new tier of privilege.

Source Comparison

Both views contain verifiable elements. UN documents confirm the absence of agreement on any reform model and the existence of resolution 77/161. Assessments of Türkiye's climate ambition rest on emissions data and policy implementation, which independent trackers and Turkish authorities interpret differently.
