COP31 in Antalya: Türkiye's Climate Diplomacy and the Zero Waste Initiative

Why It Matters

COP31 is the 2026 UN climate summit, and it will be held in Antalya, Türkiye, in November 2026. Türkiye holds the COP presidency as host, while Australia has been given a separate leadership role over the negotiations. The summit matters because it is the first time a Eastern Mediterranean, upper-middle-income G20 economy with a coal-heavy power mix hosts the world's main climate forum, and it will test how finance, adaptation and implementation commitments are balanced after the Paris Agreement's first decade.

Background

What COP31 is

A COP, or Conference of the Parties, is the annual decision-making meeting of the countries that have joined the 1992 UN Framework Convention on Climate Change (UNFCCC). The Paris Agreement (2015) is meeting-run under the same system: parties review progress, negotiate finance and adaptation rules, and set expectations for the next round of national climate pledges, known as Nationally Determined Contributions (NDCs). COP31 is the 31st such session.

Hosting rotates among the five UN regional groups. The 2026 turn belonged to the Western European and Others Group (WEOG), which includes Türkiye, Australia, most of Europe, Canada and others. Because UN climate decisions are taken by consensus, a host must be acceptable to all parties; if no host is agreed, the conference defaults to the UNFCCC secretariat's seat in Bonn, Germany.

How the Antalya arrangement came about

Both Türkiye and Australia put forward candidacies for COP31, and neither would step aside through the COP29 (Baku) and COP30 (Belém) cycle. At COP30 in November 2025, the parties reached a compromise, as announced by the governments concerned and reported by international media:

• Türkiye hosts COP31 in Antalya, and a Turkish official holds the COP Presidency, led from the Ministry of Environment, Urbanization and Climate Change.
• Australia holds a newly created 'President of Negotiations' role, with its climate minister Chris Bowen leading the negotiating track.
• A pre-COP meeting is to be held in a Pacific island country, reflecting the interests of states most exposed to sea-level rise.

This split is unusual: under normal UNFCCC practice, the host-country president both chairs the plenary and steers the negotiations. Observers therefore describe the arrangement as a negotiated workaround rather than a standing precedent. Exact job descriptions are being defined with the UNFCCC secretariat, so readers should check official COP31 communications for the latest details.

Türkiye's climate framework in brief

Turkish authorities' 2053 net-zero goal sits alongside a 2030 target. The 2023 NDC update states a reduction of up to 41 percent from the business-as-usual projection by 2030 (an emissions ceiling of 643 million tonnes of CO2-equivalent that year), with emissions expected to peak before 2038. Because the baseline is a projection rather than a fixed historical year, analysts note that it allows emissions to keep rising in absolute terms for some time. According to national inventory data published by TurkStat, annual greenhouse gas emissions are roughly 550–570 million tonnes of CO2-equivalent in recent years, with energy the largest source.

Key Players & Positions

Türkiye (host and COP President). The Ministry of Environment, Urbanization and Climate Change and the Presidency of the Republic present COP31 as an opportunity to showcase implementation, adaptation, the circular economy and the Zero Waste agenda, while seeking recognition of Türkiye's development needs.

Australia (President of Negotiations). Canberra's stated aim was to bring COP31 to the Pacific region, and the compromise gives it control of the negotiating track and a Pacific-based pre-COP. Australia's government has described the deal as a way to elevate the voice of Pacific nations.

Pacific island states. Countries such as Fiji, Tuvalu and Vanuatu have stressed that sea-level rise and loss and damage need to remain central to any COP31 outcome, regardless of the venue.

European Union and other developed economies. The EU and other WEOG members want COP31 to advance the transition away from fossil fuels agreed in principle at COP28 in Dubai, and to keep 1.5°C within reach. The EU's Carbon Border Adjustment Mechanism (CBAM), whose definitive phase begins in 2026, is also a point of interaction with Türkiye as a major EU trade partner.

Developing-country blocs. The G77 and China, the African Group and others continue to press developed countries on climate finance. At COP29 in Baku, parties agreed a new collective finance goal of at least USD 300 billion a year by 2035, a figure many developing countries consider too low.

Independent analysts. Climate Action Tracker has rated Türkiye's 2030 target as 'critically insufficient' relative to a 1.5°C pathway, pointing to continued coal-fired generation and the lack of a firm coal phase-out date. Other analysts note that Türkiye has one of the fastest-growing solar and wind sectors in its region and that the 2025 Climate Law and a planned emissions trading system create new policy tools. Both assessments can be true at once.

🇹🇷 Official Policy · Primary Sources

Türkiye's Position

The points below summarize Ankara's stated policy as expressed by the Ministry of Foreign Affairs (MFA), the Presidency of the Republic and the Ministry of Environment, Urbanization and Climate Change.

• Special circumstances and common but differentiated responsibilities (CBDR). Ankara argues that Türkiye's listing in the UNFCCC's Annex I, made in 1992, does not reflect its economic situation today and that the Marrakesh decision of 2001 recognizes its distinct position. According to the MFA's climate-change page and President Erdoğan's 2021 UN address, Türkiye considers itself a developing economy that bears less historical responsibility than the countries that industrialized earlier. The legal basis is Article 3 of the UNFCCC and Article 2(2) of the Paris Agreement, which refer to common but differentiated responsibilities and respective capabilities in light of different national circumstances.
• Climate finance. Ankara argues that climate action should be backed by predictable financing and technology transfer and that countries in its position should have fair access to multilateral climate funds. Turkish statements at UN climate conferences have repeatedly called on developed countries to meet their finance commitments, referencing Article 9 of the Paris Agreement.
• Net zero by 2053 and the national framework. The Presidency announced the 2053 target in 2021 after TBMM's approval of Paris. The Ministry of Environment, Urbanization and Climate Change describes the 2023 NDC, the 2025 Climate Law and a forthcoming emissions trading system as the framework for delivering it, together with renewable energy and nuclear power expansion.
• Zero Waste as Türkiye's flagship contribution. Led by First Lady Emine Erdoğan, the initiative began in Türkiye in 2017 and became national regulation in 2019. A UN High-Level Advisory Board on Zero Waste was established in 2020, and UN General Assembly resolution 77/161, introduced by Türkiye, created the International Day of Zero Waste on 30 March. Ankara says waste reduction and circular resource use cut methane and other emissions and are a practical, inclusive entry point for all countries.
• Host role. Turkish officials have framed Türkiye's COP31 role as that of a bridge between developed and developing countries, consistent with its G20, NATO and Mediterranean identities. Ankara has accepted the shared presidency arrangement, saying it will work with Australia and the UNFCCC secretariat. Its broader multilateral philosophy, that global institutions should be more inclusive, echoes its argument in UN Security Council Reform: What 'The World Is Bigger Than Five' Means.

Why Antalya, and What Does Türkiye Want?

Why Antalya? Antalya is Türkiye's main Mediterranean tourism and conference city, with a large international airport, extensive hotel capacity and the Antalya Expo site, which hosted the 2016 horticultural Expo. It also regularly hosts the Antalya Diplomacy Forum, an annual gathering of leaders and ministers organized under the MFA. Substantively, the Mediterranean basin is widely identified in scientific assessments, including those of the IPCC, as a climate-change hotspot warming faster than the global average, with heat, drought, wildfire and water stress risks. Hosting there lets Ankara tie the summit to regional adaptation. The sensitive politics of the same sea are covered in Eastern Mediterranean Maritime Disputes: Continental Shelf, EEZ and Mavi Vatan Explained.

What does Türkiye want? Based on its official statements, Ankara is seeking:

1. a successful, consensus-based conference that demonstrates Türkiye's diplomatic capacity;
2. progress on finance delivery and adaptation, with attention to middle-income economies;
3. wider international recognition of Zero Waste and circular-economy approaches;
4. a trade and climate policy environment, including CBAM implementation, that it does not consider discriminatory toward its exporters.

The Turkish government has not published a full list of COP31 deliverables, so these priorities should be read as inferences from public statements.
