David Carlin's Guide to the Outcomes of COP30
A big failure on fossil fuels, but progress on adaptation, just transition, and forests.
Nearly 60,000 delegates travelled to the heart of the Amazon. They came hoping that this COP would pivot from negotiation design to real-world implementation. COP30 in Belém was billed as the “COP of Truth”. It took place during a year marked by record heat, widespread climate disasters, and a growing sense of global instability. With the United States withdrawing again from the Paris Agreement and geopolitical tensions rising, expectations for the summit were layered with uncertainty.
Belém saw progress on climate finance, adaptation, and the just transition. It also exposed the widening gap between what the climate crisis demands and what governments are prepared to agree. But above all, it revealed a stark reality, after 30 COPs, the world still cannot agree on a collective plan to phase out the fossil fuels that are driving the crisis.
The Fossil Fuel Roadmap That Wasn’t
For many, COP30 was expected to be the moment when countries finally confronted the central driver of the climate crisis. More than eighty nations agreed in Belém on a roadmap to phase out fossil fuels. The hosts had championed the idea in the run-up to the summit, and support grew quickly among Latin American states, Europe, and many vulnerable nations. Even major fossil fuel exporters such as Norway signalled openness to the discussion.
By the end of the first week, that early momentum had collided with political reality. Major oil producers and several emerging economies made clear that any reference to a fossil fuel roadmap was unacceptable. Delegations spent nights in huddles trying to find compromise language, but every formulation that hinted at a structured transition away from coal, oil and gas was rejected. As the hours passed, all mention of fossil fuels was gradually stripped from the negotiating text.
The final decision that emerged in Belém did not include a single reference to fossil fuels. After thirty global climate conferences, the world is still unable to name the primary source of rising greenhouse gas emissions in an agreed UN text. It is similar to holding three decades of lung health conventions without ever mentioning smoking. The scientific evidence is clear, public support is strong, and yet political consensus on fossil fuels remains out of reach.
To avoid a complete collapse of the talks, Brazil offered an alternative. The presidency committed to launch two voluntary roadmaps, one on fossil fuel transition and one on ending deforestation. These will be developed outside the UN system and presented at future meetings. While this gesture aims to keep the conversation alive, it lacks the authority that formal COP decisions provide.
The failure to deliver a fossil fuel roadmap must be remembered as a defining outcome of COP30. It casts a long shadow over the other areas of progress and underscores the widening gulf between what climate science demands and the actions nations are willing to take.
Climate Finance: Progress, Commitments and Continuing Gaps
Climate finance remains the backbone of global cooperation. At COP30, countries reaffirmed the pathway set in Baku (COP29) to mobilise at least 300 billion dollars in annual funding for developing nations by 2035. They also recommitted to the broader goal of 1.3 trillion dollars a year from public and private sources over the same period.
These steps reflect a continued strengthening of the finance architecture. They also highlight areas where the system is still fragile. Many developing countries questioned whether these commitments can be met without the involvement of the United States. Others asked how the promised resources will flow when existing funds remain difficult to access and slow to disburse. The absence of the United States’ financial and diplomatic weight hung over every negotiation.
Forest protection also received an infusion of funding. Support for Brazil’s Tropical Forests Facility reached more than 9 billion dollars. While this represents a significant sum, it is still far below what rainforest countries have said is needed to halt deforestation and support the communities that depend on these ecosystems.
Finance is moving, but not at the scale or speed required in a world already experiencing costly climate impacts.
Adaptation: A Step Forward, But Short of What Vulnerable Nations Need
Belém had already been described as an “Adaptation COP”. The headline outcome was the agreement to triple adaptation finance by 2035. This represents progress, particularly after several years of stalled conversations. However, many vulnerable nations had called for tripling by 2030. Extending the timeline by an extra five years delays resources that communities already need.
The Global Goal on Adaptation advanced as well, but not without deep frustration. Technical experts had spent two years developing a set of indicators to measure progress on adaptation efforts. In the final hours of COP30, the list was significantly shortened and diluted. Several African and Latin American countries described the revised indicators as unclear and unusable. They warned that adaptation metrics that fail to reflect realities on the ground weaken the entire framework.
Despite these concerns, countries did agree to expand reporting and transparency on adaptation efforts. This may help strengthen accountability, but the gap between adaptation needs and adaptation finance remains large and growing.
Just Transition: An Important Institutional Advance
One of the most meaningful outcomes of COP30 was the agreement to create a just transition mechanism. This new platform is intended to help countries manage the shift from fossil fuel-based economies in ways that support workers, protect communities, and broaden the economic benefits of clean energy.
The just transition mechanism was welcomed by civil society, unions, and many developing countries. It offers a practical tool for planning the economic and social changes that accompany decarbonisation. As countries grapple with how to replace fossil systems with cleaner alternatives, this mechanism can help shape more stable and equitable transitions.
In a summit where progress was uneven, this stands out as a genuine achievement.
Trade, Cooperation and a Shifting Geopolitical Landscape
Trade took on an unexpectedly central role at COP30. Several countries pressed for language addressing concerns about carbon border measures, particularly the European Union’s new import levy on high-emissions goods. As a result, COP30 agreed to begin a series of dialogues on trade and climate cooperation.
This reflected wider geopolitical dynamics. With the United States absent from the talks, the European Union found itself increasingly isolated. China and India emphasised trade fairness and flexibility. Russia and Saudi Arabia played a more assertive role in blocking mitigation language. Many observers described Belém as a turning point that reflected a new distribution of global influence.
While trade discussions may help align climate policy with a rapidly changing world economy, they also reveal the difficulties of maintaining unity in a fragmented geopolitical environment.
Forests and Nature: Promising Signals and Persistent Gaps
Brazil entered COP30 determined to put forests at the heart of global climate action. Support for the Tropical Forests Facility grew steadily over the two weeks, and more than 90 countries backed the call for ending deforestation.
Yet the summit did not deliver a negotiated roadmap to halt and reverse forest loss. As with fossil fuels, the roadmap was shifted to a voluntary process outside the formal UN structure. This was disappointing for many countries, especially given the symbolic importance of hosting a climate summit in the Amazon.
Forests remain one of the most effective natural climate solutions, and protecting them is essential for limiting warming. Belém delivered momentum, but not the structural progress many hoped for.
Brazil’s Ambitions and the Reality of Consensus Politics
President Lula opened COP30 with bold aspirations. He called for roadmaps to phase out fossil fuels and stop deforestation. His vision was widely supported by civil society and many governments.
The presidency, however, faced a familiar challenge. Delivering an ambitious agreement in a process that requires consensus from nearly 200 countries was always unlikely. The final COP text reflects this tension. It includes new initiatives on implementation and cooperation, but it excludes the central element that many believed defined the success of Belém: a clear commitment to move away from fossil fuels.
Brazil’s leadership was praised for keeping the talks from collapsing. At the same time, the gap between the president’s ambition and the final negotiated outcome was unmistakable.
Is the COP System Still Fit for Purpose?
The most difficult question raised in Belém was about the COP process itself. That process was designed to produce incremental progress through consensus. Our moment of climate crisis requires urgent, coordinated action. Unfortunately, the current COP model is not aligned with that reality.
Several countries called for discussions on reforming COPs, including changes to voting rules, streamlined negotiation tracks, and greater reliance on coalitions of willing actors. These conversations were promising, but no major reforms were agreed. The need for change is clear, and Belém made that hard to ignore.
Looking Ahead to COP31
COP31 will be hosted by Türkiye, with Australia taking an unusual role in running the talks. This dual structure will add complexity, but might offer chances for new breakthroughs.
The coming year will be defined by three processes. First, countries will submit strengthened national climate plans. Second, Brazil will lead voluntary work on fossil transition and deforestation roadmaps. Third, negotiations will continue on finance, trade and adaptation.
The stakes for 2026 could not be higher. The credibility of the COP system, the global trajectory of emissions, and the future of the Paris Agreement will depend on what countries choose to do over the next twelve months.
In sum, COP30 saw progress in places, but climate change demanded more
COP30 made progress on climate finance, adaptation, just transition, and forest protection. These achievements matter. They also fall short of what science tells us is required.
Without meaningful commitments to phase out fossil fuels, the world remains on a path to deeper climate instability. As the world looks to COP31, the task ahead is clear. Countries must turn promises into implementation and voluntary roadmaps into real change. The window for keeping 1.5 degrees within reach is rapidly closing, and the need for decisive action has never been more urgent.
