Brazilian President Luiz Inacio Lula da Silva will attend the COP31 climate summit in Antalya, Turkey, the Brazilian presidency said on October 30, 2026, adding a prominent voice to a leaders’ gathering that organisers hope will turn long-standing climate promises into measurable action. Lula is scheduled to arrive in Antalya on November 10 for the leaders’ summit on November 11 and 12, before travelling onward to the Philippines for the ASEAN summit on November 13. His confirmation came shortly after his re-election in Brazil the previous Sunday, and it places Brazil at the centre of a handover moment: Brazil currently holds the COP presidency and will hand it to Turkey, which will oversee the conference over the next year under a shared arrangement with Australia, which is coordinating the diplomatic negotiations.
So far, 77 heads of state and government have confirmed their participation in the summit, according to the Brazilian presidency’s announcement reported by Reuters. That figure is significant not because attendance alone guarantees an outcome, but because the leaders’ segment sets the political tone for the two weeks of negotiation that follow. When heads of government are present, delegations tend to arrive with clearer instructions, and disagreements that might otherwise drift through technical sessions can be resolved, or at least narrowed, at the top. Conversely, a thin leaders’ turnout can leave negotiators without the authority to close difficult trade-offs on finance, emissions cuts and adaptation support.
The conference itself runs from November 9 to 20, 2026, at the Antalya Expo Center, according to the United Nations Framework Convention on Climate Change, known as the UNFCCC. Formally, it is the 31st session of the Conference of the Parties to the UNFCCC, together with the meetings of the parties to the Kyoto Protocol and the Paris Agreement. In practice, it is the largest annual forum where almost every country in the world negotiates together on climate change, and where governments, businesses, cities and civil society groups present plans, projects and demands side by side. The Turkish presidency is led by Murat Kurum, who has been nominated as COP31 president, while Chris Bowen of Australia will serve as president of negotiations, a division of roles that reflects the shared Turkey-Australia arrangement for this cycle.
What the Antalya climate summit must deliver
The central test in Antalya is implementation. For more than a decade, countries have announced targets, frameworks and long-term goals. The question now, repeatedly raised by negotiators and by vulnerable countries in particular, is whether those commitments are being put into practice quickly enough to matter. The European Union’s negotiating position, adopted by its Council on October 12, 2026, frames COP31 as a moment that must mark a step-change in delivery of the Paris Agreement. EU ministers called for the effective implementation of nationally determined contributions, known as NDCs, which are the climate action plans each country submits under the Paris Agreement, and for the urgent submission of any NDCs that remain outstanding.
That emphasis matters because NDCs are the main mechanism through which the Paris Agreement is supposed to work. The agreement does not impose a single global emissions quota on each country. Instead, each government sets its own contribution, and the collective effect of those contributions is reviewed over time. If many plans are missing, vague or unimplemented, the gap between what countries have promised and what the atmosphere actually requires will remain wide. The EU position also stresses the need to deliver collectively on the outcomes of the first global stocktake, the formal review completed at an earlier COP that assessed progress toward the Paris goals. That includes the transition away from fossil fuels and an accelerated clean energy transition, with clean electrification identified as an important component.
Climate finance will run through almost every discussion in Antalya, even where it is not the headline item. Developing countries have long argued that they cannot implement ambitious plans without predictable funding for clean energy, resilient infrastructure and adaptation measures such as flood defences, drought-resistant agriculture and early warning systems. Developed countries, in turn, point to their existing contributions and to the growing role of private finance. The EU Council addressed climate finance in separate conclusions adopted on October 9, 2026, noting that the EU and its member states continue to be among the world’s largest public contributors. The October 12 conclusions themselves did not announce a new climate finance amount, a limitation that negotiators from recipient countries are likely to probe in Antalya. The summit’s agenda, which organisers have described as covering nearly 100 items across 12 thematic days, includes dedicated sessions on finance, energy security, transport and electrification, food, agriculture and health, industry, nature and sustainable development.
The 1.5-degree goal and the overshoot debate
One of the most sensitive questions in Antalya will be how to talk honestly about the Paris Agreement’s goal of limiting warming to 1.5 degrees Celsius above pre-industrial levels. EU ministers acknowledged in October that the goal is likely to be exceeded, at least temporarily. Their position does not abandon the target. Instead, it argues for urgent action to avoid every additional fraction of a degree of warming and to return to the 1.5-degree trajectory in line with the best available science. Ministers described an overshoot-peak-decline pathway as the best remaining option to keep warming below 1.5 degrees by the end of the century.
That language will be contested, and it should be understood for what it is: a negotiating position, not a forecast that the goal will be met. Scientists and negotiators use the term overshoot to describe a period in which temperatures rise above a target before measures such as emissions cuts and carbon removal bring them back down. Supporters of this framing argue that it keeps ambition alive and gives countries a credible path back, rather than declaring the target dead at the first breach. Critics argue that overshoot language can be used to justify delay, because it implies that excess warming can simply be undone later, even though some impacts, such as the loss of glaciers, coral reefs and species, cannot be reversed on human timescales. Small island states and least developed countries, which face the most immediate risks from sea-level rise and extreme weather, are likely to press hardest on this point, insisting that minimising the size and duration of any overshoot is itself a moral and practical obligation.
A pre-COP ministerial meeting held in Fiji and Tuvalu in early October underscored that concern. A statement from that meeting said deep, rapid and sustained emissions reductions are required to minimise the magnitude and duration of overshoot. Pacific leaders have consistently argued that their nations should not be treated as an afterthought in global negotiations, and the COP31 Pacific Partnership involving Australia and Pacific partners is intended to keep Pacific voices and solutions at the centre of the process. Whether that partnership translates into concrete finance and adaptation outcomes in Antalya will be one measure by which Pacific delegations judge the summit.
Why Lula’s presence carries weight beyond Brazil
Lula’s attendance matters for reasons that go beyond protocol. Brazil is one of the world’s largest countries, a major agricultural producer, and home to a large share of the Amazon rainforest, whose preservation is central to global climate efforts. As the outgoing COP president, Brazil also carries institutional knowledge from the previous round of negotiations and a responsibility to help ensure continuity between presidencies. The handover to Turkey is not merely ceremonial. The incoming presidency sets the agenda, chairs key sessions and, in the final days, brokers compromises when talks stall. A visible, engaged handover, with both the outgoing and incoming leadership present, can help prevent the loss of momentum that sometimes occurs when presidencies change.
Lula’s re-election the previous Sunday also gives his attendance a domestic political dimension, though its international significance should not be overstated. A newly re-elected leader attending a major summit can speak with a fresh mandate, but that mandate does not by itself resolve disagreements among nearly 200 parties. Brazil’s own climate record will be examined in Antalya, including its policies on deforestation, land use, energy and agriculture, just as every major emitter’s record will be. The value of Lula’s presence is therefore best measured not by the announcement itself, but by what Brazil brings to the table in terms of updated plans, finance positions and willingness to compromise on contested texts.
The United Kingdom’s prime minister, Andy Burnham, was also reported among those planning to attend, according to the same Reuters report, illustrating the breadth of the leaders’ segment. Attendance lists will continue to change in the days before the summit, and some leaders may send senior ministers instead. What matters for negotiators is not the final headcount alone, but whether the leaders who do attend arrive ready to make decisions on the issues that technical negotiators cannot settle on their own, particularly finance and the pace of the fossil fuel transition.
What to watch in the two weeks ahead
Several markers will indicate whether Antalya is producing real progress. The first is the treatment of missing and updated NDCs. If countries that have not yet submitted plans do so, and if updated plans show higher ambition rather than restated targets, that will be a tangible outcome. The second is finance: whether negotiators agree on clearer delivery timelines, reporting rules and support for adaptation, rather than repeating general commitments. The third is the final decision text. COP outcomes are often judged by a few paragraphs that either strengthen, weaken or merely restate previous language on fossil fuels, renewable energy and loss and damage, the term used for support to countries suffering climate impacts they did not cause and cannot adapt to alone.
Observers should also watch the thematic days, which are designed to connect negotiations to practical sectors. Sessions on food, agriculture and health at the start of the conference will test whether climate policy is being linked to everyday concerns such as crop resilience and heat-related illness. Later sessions on energy security, transport, cities and industry will show whether governments and companies are presenting projects that can be built, financed and replicated, or only aspirations. The leaders’ summit on November 11 and 12 sits in the middle of this sequence, and its statements will be read closely for signals about where political compromises might be possible in the second week.
It is important to keep expectations proportionate. No single COP resolves climate change. Each conference is one step in a process that began with the UNFCCC treaty in 1992 and the Paris Agreement in 2015, and that continues through national policies, investments and court decisions far from the conference halls. Antalya’s success will therefore be judged in stages: first by what is agreed in the negotiating rooms, then by what governments actually implement in the months that follow. For readers following the summit from home, the most useful question is not whether leaders used ambitious language in Antalya, but whether the plans, money and timelines agreed there make emissions cuts and adaptation support more likely in 2027 and beyond.
