new climate promises takeaways from the un summit of the future

Largely focusing on climate change, key measures include net-zero by 2050, SDG financing, and reversing biodiversity loss, will the Pact for the Future deliver real change? The skater girl doesn’t skate. The punk doesn’t rage. Identity now comes prepackaged, flattened into moodboards, starter packs, and TikTok’s endless... Stepping into a C2 elevator feels less like entering a quiet campus space and more like being swallowed by a wall of competing announcements. In three decades of these meetings aimed at forging global consensus on how to prevent and deal with global warming, this will go down as among the most divisive.

Many countries were livid when COP30 in Belém, Brazil ended on Saturday with no mention of the fossil fuels that have heated up the atmosphere. Other nations - particularly those with most to gain from their continued production - felt vindicated. The summit was a reality check on just how much global consensus has broken down over what to do about climate change. Here are five key takeaways from what some have called the "COP of truth". The most important thing to come out of COP30 is that the climate 'ship' is still afloat 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. Half of global greenhouse gas emissions are now covered by a 2035 climate pledge following a key UN summit this week, Carbon Brief analysis finds. China stole the show at the UN climate summit held in New York on 24 September, announcing a pledge to cut greenhouse gas emissions to 7-10% below peak levels by 2035.

However, other major emitters also came forward with new climate-pledge announcements at the event, including the world’s fourth biggest emitter, Russia, and Turkey. Following the summit, around one-third (63) of countries have now announced or submitted their 2035 climate pledges, known as “nationally determined contributions” (NDCs). The NDCs are a formal five-yearly requirement under the “ratchet mechanism” of the Paris Agreement, the landmark deal to keep temperatures well-below 2C, with aspirations to keep to 1.5C, by the end of this... 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. The 2025 UN Climate Summit, held in Geneva, Switzerland, brought together leaders from nearly 200 nations to address the pressing challenges of climate change. As the world faces rising temperatures, extreme weather events, and unprecedented environmental crises, the summit aimed to strengthen global commitments to sustainability and carbon neutrality. While the summit highlighted ambitious goals, significant challenges remain: The 2025 UN Climate Summit reaffirmed the urgency of addressing the climate crisis and showcased promising commitments from nations worldwide. While challenges remain, the global community’s collective action offers hope for a sustainable future.

As the world looks ahead, the success of these commitments will depend on continued collaboration, innovation, and accountability. Stay tuned for updates on the progress of these critical climate initiatives. 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. It’s been an action-packed first few days in Baku.

As of Wednesday morning, three countries—Brazil, the UAE, and the UK—have all released parts or all of their new nationally-determined contributions, or NDCs, months ahead of the February 2025 deadline. Experts have welcomed the leadership these countries have shown by announcing early NDCs, and praise the ambitious targets set by the UK government. But experts also say that two of these new plans—from Brazil and the UAE, two of the three Troika members tasked with leading COP29 to success—are not aligned with Paris targets, and do not... Nationally-determined contributions, or NDCs, are commitments made by countries under the Paris Agreement to reduce their greenhouse gas emissions and adapt to climate change impacts. Each country determines its own contribution based on its national circumstances and capabilities. Experts say that appropriately aggressive NDCs must pass a series of thresholds, including commitments to phase out fossil fuels and scaling up commitments for climate finance.

According to the Intergovernmental Panel on Climate Change (IPCC) and the first Global Stocktake of the Paris Agreement, emissions cuts of 60% by 2035 compared to 2019 are recommended in these new NDCs. But thus far, only the UK goes above and beyond this benchmark, while Brazil and the UAE’s plans are lacking the aggressive leadership promised by the Troika. “We had a catastrophic year with events we’ve never seen before, but what people didn’t understand is that this is the new normal,” Prof Niklas Höhne, NewClimate Institute, a Climate Action Tracker partner, said. “National governments have set net-zero targets and acknowledged the need to decarbonize, but what’s missing is short-term action. That’s why new NDCs for 2035 are so important. If we look at all the NDCs on the table so far, GHGs will remain stable until 2035, and if we stay on this course, we will emit twice as much as what is...
