What Is COP31 in Antalya? Dates, Hosting Deal and Key Issues

In a few days the world’s climate agenda moves to Antalya. The 31st session of the UN climate conference, COP31, takes place in Antalya, Türkiye, from 9 to 20 November 2026. Over those two weeks the news will be full of words like “negotiations”, “draft text” and “presidency”, but it is rarely explained what a COP actually is, who decides what, and why any of it matters to an ordinary person. Coming from an environmental-engineering background, I wanted to set out the basic picture in plain language before the conference opens. This is not a prediction of outcomes; it is a guide to what is on the table.

What is a COP, and who takes part?

COP stands for Conference of the Parties. The “parties” are the countries, plus the European Union, that have joined the UN Framework Convention on Climate Change (UNFCCC), adopted in 1992. The conference is the convention’s top decision-making body. It meets every year, and decisions are normally taken by consensus, meaning texts that no party openly objects to.

Several meetings actually run side by side in the same fortnight. The Antalya session is formally labelled “COP31–CMP21–CMA8”: the 31st meeting under the Convention, the 21st meeting of the Kyoto Protocol parties and the 8th meeting of the Paris Agreement parties. These days most of the substantive work happens in the Paris Agreement meeting (CMA).

It is not only government delegations who attend. Scientists, civil society groups, local governments, businesses and journalists are accredited too. While formal negotiations happen behind closed doors, hundreds of side events, panels and exhibitions run on the same site.

An unusual arrangement: Türkiye hosts, Australia runs the talks

Both Türkiye and Australia bid to host COP31. After a long stand-off, a compromise was reached during COP30 in Belém, Brazil, in November 2025. According to the Australian Prime Minister’s office:

Türkiye physically hosts the conference and the World Leaders Summit in Antalya and holds the COP Presidency. Murat Kurum, Minister of Environment, Urbanisation and Climate Change, is the COP31 President.
Australia takes on the role of “President of Negotiations”, running from the end of COP30 to the end of COP31, with exclusive authority over the formal negotiations. Climate and Energy Minister Chris Bowen fills that role.
A Pacific pre-COP was also agreed. It was held in Fiji and Tuvalu in early October 2026.

Put simply: Australia steers the bargaining over the official texts, while Türkiye hosts and leads the “Action Agenda”, the voluntary, implementation-focused initiatives that sit alongside the negotiations. This kind of split is not a familiar model in COP history, and Antalya will be the first time we see how it works in practice.

Tip: When reading coverage, it helps to tell the "COP President" apart from the "President of Negotiations". Stories about final decision texts mostly concern the negotiations side; announcements of new initiatives and pledges mostly belong to the Action Agenda.

The main issues on the table

Every COP has a long agenda, but pre-conference analyses, for example from United Nations University and Carbon Brief, highlight a similar set of issues for COP31.

Adaptation

Preparing for the impacts of climate change, living with floods, droughts and heatwaves, is rising up the agenda. COP30 adopted 59 indicators under the Global Goal on Adaptation, but parties could not agree on the details of that goal at the Bonn intersessional meetings in June 2026. There is also the question of how the pledge to triple adaptation finance for developing countries by 2035 will be delivered.

Climate finance

A new climate finance goal (NCQG) was adopted at COP29 in Baku in 2024. Developing countries pushed for a dedicated “climate finance work programme” on the COP31 agenda to follow up on it. Who pays how much, from what sources and on what terms remains one of the hardest questions.

The second global stocktake

The Paris Agreement requires a collective review of progress every five years. The first one concluded in Dubai in 2023. According to the UNFCCC, the second global stocktake starts at this conference and concludes in 2028.

New national climate plans (NDCs)

Countries were expected to submit new plans covering the period to 2035 during 2025. Carbon Brief’s early-November 2026 tracker counts around 150 parties that have done so, while some have not. Whether the plans add up to enough is one of the big background questions at the conference.

Just transition and the Action Agenda

COP30 agreed a just-transition mechanism whose details are still being shaped. Türkiye, for its part, is emphasising Action Agenda themes such as electrification, waste reduction and emissions from buildings. Moving away from fossil fuels is not a formal agenda item, though it is widely expected to come up in the corridors.

Why it matters for Türkiye

Hosting means visibility first of all. Türkiye’s own climate policies, its 2053 net-zero target and the Climate Law that entered into force in 2025 will be in the spotlight. There are also some concrete links:

Trade: The EU’s Carbon Border Adjustment Mechanism entered its definitive phase at the start of 2026. For Turkish exports of steel, aluminium, cement and fertilisers to the EU, carbon pricing is now a direct cost question.
Adaptation needs: The Mediterranean basin is warming faster than the global average. Drought, wildfires and coastal risks make Türkiye a direct stakeholder in adaptation debates.
Access to finance: Part of the investment needed for the green transition comes from international funds and development banks. How their rules evolve affects projects in Türkiye too.

What should an ordinary reader watch?

COP coverage can look like pure diplomatic theatre. But decisions taken here can, over the years, feed into energy bills, urban planning, farm support and exporters’ costs. A few questions I find useful when following along:

Does a concrete number or timeline emerge on adaptation finance and indicators?
Is the finance debate channelled into a new work programme, or postponed?
Which countries and institutions back the initiatives on Türkiye’s Action Agenda?
Do the decision texts contain clear steps for implementing promises made at earlier COPs?

Note: Draft texts change frequently in the final days, and closing sessions often run over time. For a fair assessment, wait for the texts adopted at the closing plenary and the UNFCCC's official announcements.

Key takeaways

COP31 runs 9–20 November 2026 in Antalya, alongside the 8th meeting of the Paris Agreement parties.
Türkiye is host and COP President; Australia is the "President of Negotiations" running the formal talks.
Key issues: adaptation indicators and finance, climate finance, the second global stocktake and new NDCs.
For Türkiye, the direct links are trade (CBAM), adaptation needs and access to finance.

Are COP31 decisions legally binding?

It depends on the text. The Paris Agreement is an international treaty, but the content of each country's national targets is set by that country. COP decisions mostly clarify rules, timelines and processes.

Can anyone attend?

The negotiation area (the "blue zone") is open only to accredited delegations, observer organisations and press. Hosts usually also run a public area for events; check the official conference announcements for details.

Why are two countries sharing the role?

When Türkiye and Australia both bid for the same year, a compromise was struck at COP30: Türkiye hosts and holds the COP Presidency, while Australia runs the formal negotiations. This is an unusual split in COP history.

Where can I follow the results?

Adopted texts are published on the UNFCCC's official website. For daily summaries, established climate news outlets and research institutes are helpful.
