momentum gathers towards cop30 as close to 100 countries unfccc

UN Climate Summit takes place against a backdrop of extreme weather, underlining urgency of more ambitious climate action ahead of COP30 in Brazil. Some 100 countries, including nearly 40 Heads of State and Government, have declared their commitment to new climate targets to try to rein in temperature increase. The announcements came at a Climate Summit convened by UN Secretary-General António Guterres and President Luiz Inácio Lula da Silva of Brazil during the 80th session of the UN General Assembly and ahead of... For the first time, several major economies including China – the world’s largest emitter – as well as Nigeria announced economy-wide emissions reduction targets covering all greenhouse gases and all sectors. Other nations detailed ambitious renewable energy goals, plans to curb methane emissions, strategies to safeguard forests, and measures to phase out fossil fuels. “The science demands action.

The law commands it. The economics compel it. And people are calling for it,” declared the UN Secretary-General in his opening statement to the Climate Summit. The 2025 UN climate talks wrapped on Saturday, Nov. 22 after negotiations pushed into overtime. The resulting decision secured some important wins, both inside and outside the negotiations.

But it omitted some of the big-ticket items many hoped to see. With efforts to halt temperature rise severely off track and climate disasters becoming ever-more destructive, the summit (COP30) aimed to establish clear pathways to deliver past pledges and put the world on a safer... A key question was how countries would address lagging ambition in their new climate commitments (NDCs). Hopes that countries would commit to roadmaps to end fossil fuel use and halt deforestation were ultimately dashed after opposition from petrostates. The final decision only included new voluntary initiatives to accelerate national climate action, though the Brazilian Presidency intends to move forward with fossil fuel and deforestation roadmaps outside of the formal COP talks. Building resilience to climate impacts took center stage, with COP30 securing a new target to triple finance for climate adaptation.

The COP also laid out practical solutions to increase finance for the low-carbon transition. In an era of trade wars and tariffs, negotiators also agreed for the first time to hold discussions on how trade policies can help — or hinder — climate action. Against the backdrop of the Amazon, nature also saw advances, including a new fund for tropical forest conservation. Indigenous Peoples and other local communities were recognized like never before. And outside the formal negotiations, the summit saw a raft of new pledges and action plans from cities, states, countries and the private sector. It is clear that we are moving from negotiations to implementation, and from wrangling over what to do to how to do it.

These victories matter. It shows that international cooperation can still deliver, despite deepening divides on climate action and a difficult geopolitical context. All eyes turned to Belém this weekend as divided nations scrambled to deliver a final deal at a UN climate conference battered by “roaring political headwinds”. COP30 kicked off with high hopes for a historic outcome, if not solely due to its poignant proximity to the Amazon rainforest, a crucial regulator of the climate. It was also the first UN climate talk where a US delegate was completely absent, following Donald Trump’s controversial decision to abandon the Paris Agreement. The charismatic heft of Brazilian President Luiz Inácio Lula da Silva fuelled the push for an ambitious final deal.

But, did any of this actually help in the end - and what has two weeks of strung-out negotiations actually achieved? Here are five key outcomes from COP30, and what they mean for the future. While transitioning away from fossil fuels wasn’t originally on COP30’s official agenda, political momentum around the issue rapidly transformed it into a flashpoint discussion during negotiations. The 30th UN Climate Change Conference of the Parties (COP 30) brought the world to Belém, Brazil, for a negotiating round surrounded by rising climate impacts and growing expectations. After two weeks of talks, countries adopted a bundle of decisions now referred to as the Belém Political Package. Here are five key outcomes of COP 30:

Adaptation finance is the funding that helps countries cope with climate impacts already unfolding, such as building flood-resilient roads, improving water storage during droughts or expanding early warning systems. At COP 30, countries indicated that adaptation finance should increase threefold by 2035. While this is not yet a binding commitment, it is a major political signal. Current funding falls far short of what vulnerable countries need, and impacts are escalating quickly. A clear expectation to scale up resources over the next decade gives international institutions and national governments a direction of travel, even as the details on contributions still need to be negotiated. Countries’ Nationally Determined Commitments (NDCs) while providing progress if implemented are falling short to reach the mitigation necessary to avoid 1.5°C.

In an effort to bridge the gap between current climate targets and the 1.5°C goal, the Baku-Belém Political Package establishes two initiatives designed to support nations in strengthening and achieving their commitments. The "Belém Mission to 1.5" aims to encourage higher ambition in national climate plans (NDCs) by fostering dialogue on the necessary international cooperation and investment. This is complemented by the "Global Implementation Accelerator," a voluntary and cooperative platform intended to assist countries in moving from planning to action, facilitating the practical delivery of mitigation and adaptation measures needed to... One of the summit’s most consequential outcomes was the creation of a just transition mechanism. In line with the Sustainable Development Goals (SDGs), just transition refers to the idea that climate action should not leave anyone behind, particularly communities and workers whose livelihoods depend on fossil fuels or carbon-intensive... It also means giving developing countries the support they need to grow their economies in cleaner, more resilient ways.

The new Belém Action Mechanism (BAM) will serve as a platform to coordinate assistance, share best practices, mobilize resources and track progress. Its establishment means that fairness in the global shift toward sustainable economies is no longer only a political slogan but now has a formal home within the UN climate system. For years, Parties have been trying to define how to measure global progress on adaptation, which is a difficult task considering climate resilience looks different from place to place. COP 30 finally produced an agreed set of indicators for the Global Goal on Adaptation (GGA). These will help evaluate improvements in areas such as water security, food systems, infrastructure resilience, the reach of early warning systems and access to adaptation finance. Negotiations were difficult, and many governments stressed that the indicators will need further refinement, leaving significant work for coming COPs.

Still, having a first version in place gives countries a common framework to assess whether adaptation efforts are on track.
