COP31 and Zero Waste: What Climate Diplomacy Adds to Türkiye's Diplomatic Horizon

Why It Matters

COP31 gives Türkiye its first turn at the centre of the UN climate process, and it arrives with a signature national brand, the Zero Waste initiative, that Ankara has already taken to the General Assembly. The question for observers is whether a host that is both an emerging economy and a fossil-fuel-reliant energy consumer can turn convening power into negotiated results. This guide explains how the hosting arrangement works, how the UN climate system operates, what Zero Waste is, how Ankara links climate to development diplomacy, and what critics say.

Background

How the UN climate negotiation system works

The UN climate regime rests on the 1992 UN Framework Convention on Climate Change (UNFCCC), which entered into force in 1994. The Conference of the Parties (COP) is its supreme decision-making body and meets annually. The 1997 Kyoto Protocol and the 2015 Paris Agreement (in force since November 2016) added binding procedures and a shared temperature goal: holding warming well below 2°C and pursuing efforts to limit it to 1.5°C.

Three features matter for understanding COP31:

• Consensus. Decisions are in practice adopted without objection from any Party, so negotiating outcomes reflect the lowest common denominator unless the presidency brokers wider agreement.
• Rotating presidency. The COP presidency rotates among the UN regional groups. The host government appoints a President, who chairs plenaries, runs consultations and sets an action agenda, while the UNFCCC Secretariat handles the technical process.
• NDC cycle. Under Paris, each Party submits a Nationally Determined Contribution (NDC) every five years, reviewed collectively through the Global Stocktake. At COP29 in Baku (2024), Parties agreed a new collective finance goal of at least USD 300 billion per year by 2035 for developing countries, a figure many developing states considered too low.

The COP31 arrangement

Both Türkiye and Australia sought to host COP31, and both belong to the Western European and Others Group (WEOG), whose turn it was. Because consensus is required even for choosing a host, the contest was resolved through a compromise announced around COP30 in Belém (November 2025). Under that arrangement, as publicly described by the parties and the UNFCCC process:

• COP31 takes place in Antalya, Türkiye, in November 2026, with a Turkish COP President.
• Australia holds a dedicated negotiations-leadership role (described as 'President of Negotiations'), with its climate minister Chris Bowen leading it.
• Pre-COP consultations are to be held in the Pacific, reflecting the priorities of island states most exposed to sea-level rise.

Readers should check the UNFCCC website for final dates, venue arrangements and the division of responsibilities, since host-country agreements are formalised after the political announcement.

Chronology

Origin and goals of Zero Waste

Zero Waste began as a national programme in 2017 to reduce waste generation, improve separate collection and recycling, and treat waste as a resource within a circular-economy logic. It was institutionalised through the 2019 Zero Waste Regulation, which set obligations for public institutions, businesses and municipalities. Turkish authorities report steadily rising recycling rates under the programme; readers should consult the Ministry of Environment, Urbanisation and Climate Change for current figures, since methodologies differ across countries.

Internationally, the project moved through the UN system. A High-Level Advisory Board on Zero Waste was created in 2020, and on 14 December 2022 the General Assembly adopted resolution 77/161, 'Promoting zero-waste initiatives to advance the implementation of the 2030 Agenda', designating 30 March as the International Day of Zero Waste. The Day is facilitated jointly by UNEP and UN-Habitat and was first observed in 2023. The resolution links waste reduction to the Sustainable Development Goals, notably responsible consumption and production (SDG 12) and sustainable cities (SDG 11), and to the reduction of methane and other emissions from landfills.

Key Players & Positions

• UNFCCC Secretariat and UN Secretary-General. They stress that the world remains off track for 1.5°C and that NDCs must be strengthened and financed. Their reports are the baseline most media and governments cite.
• Australia. As co-leader of the COP31 arrangement, Canberra emphasises ambition on mitigation and Pacific priorities, and has framed the compromise as a way to combine host-country logistics with Pacific voice.
• Pacific Island states and the Alliance of Small Island States. They push for adaptation finance, loss and damage funding and a firm 1.5°C pathway.
• The European Union. It presses for faster phase-out of fossil fuels and has a 2030 emissions-reduction target of at least 55% relative to 1990 under its own legislation; it has also introduced a carbon border adjustment mechanism that affects Turkish exporters.
• Developing-country groups (G77 and China, LMDC, African Group). They insist on finance, technology transfer and the principle of common but differentiated responsibilities, and many argue that developed countries have not met earlier finance promises.
• Major fossil-fuel producers. Several resist language on phasing out fossil fuels, and consensus rules give them substantial leverage over final texts.
• Civil society and think tanks. Groups such as the Climate Action Tracker and Turkish environmental organisations scrutinise national targets and the host's own record.

What to Watch

• Whether Türkiye submits or strengthens its NDC and what baseline it uses.
• How the Turkish presidency and Australia divide agenda-setting and negotiation roles.
• Progress on the finance goal agreed at COP29 and on adaptation finance.
• Implementation of the 2025 Climate Law and the emissions-trading scheme.
• Whether Zero Waste and circular-economy language enters COP31 outcome texts.

Key Terms & Related Guides

• COP (Conference of the Parties): the annual meeting of the states that are Party to the UNFCCC; decisions require consensus.
• NDC (Nationally Determined Contribution): a country's own climate pledge under the Paris Agreement, updated every five years.
• Zero Waste: a Turkish-originated approach that prioritises prevention, reuse and recycling; the UN observes the International Day of Zero Waste on 30 March.
• Business-as-usual (BAU) baseline: a projection of emissions without new policies, used by Türkiye to express its 2030 target.
• Special circumstances: a status recognised in UNFCCC decisions of 2001 that distinguishes Türkiye's position from that of other Annex I Parties.
