The dust is settling after COP30, and two things have become clear. First, the outcomes of the world’s most important climate conference were disappointing. Secondly, those outcomes had less to do with the limits of climate science and more to do with geopolitics.
If they want to meaningfully push for better climate agreements, future COP presidencies will need to take a more proactive role in orchestrating climate negotiations and do so in a way that accounts for the new geopolitical reality. If they don’t, climate action will remain mostly talk.
The shortcomings in Belém
Brazil’s COP30 presidency placed three big bets on the 2025 climate summit: it would be “the COP of implementation;” the rainforest setting would unify actors; and wider participation would unlock new avenues for progress.
Instead, the summit – held in Belém (the “gateway to the Amazon”), in the most deforested country on earth – ended with no roadmap for fossil fuel phaseout, an agreement that only briefly mentions deforestation, and an institutional apparatus less trusted than it was at the start.
In part, these outcomes reflect rare missteps by COP President André Aranha Corrêa do Lago, who pushed contentious issues like unilateral trade measures (including the EU’s carbon border tax) into a separate negotiation track and dedicated only a small part of the agenda to political conversation.
But COP30 also suffered from broader issues that are straining multilateralism. Conflicts in Ukraine and the Middle East have made it harder to form cross-regional coalitions, record debt distress in developing countries has weakened trust in global institutions, and collaborative efforts to regulate global shipping emissions and reform international taxation have stalled.
How geopolitics show up at COP
Climate diplomacy is becoming less insulated from these geopolitical pressures. Observers noted this during COP28 (Dubai), and since then, it has become more pronounced, while COP hosts have done little in response.
Great-power rivalry is now shaping even technical negotiations, trust in the idea of COP is waning, and the lines between climate and trade are increasingly blurred. At COP30, we saw this firsthand in the form of three key shifts compared to past summits:
Feasibility is no longer the binding constraint. The scientific, technical, and policy cases for rapid decarbonisation have never been stronger – pathways to limit warming to 1.5°C have been well mapped by the UN’s Intergovernmental Panel on Climate Change; onshore wind and solar power are respectively 60% and ~80% cheaper than in 2015; and each year of inaction measurably raises the costs of mitigation.
But inside the negotiation rooms in Belém, we saw countries not only weighing climate commitments against fiscal, trade, and energy priorities, but also calibrating their positions to avoid antagonising key international partners (chiefly the United States) or empowering domestic political rivals in upcoming elections.
Narrative power has reached its limits. Narratives once turbocharged climate deals, from stories of shared purpose building momentum at COP21 (Paris) to discussions of climate justice pushing “loss and damage” to the fore at COP27 (Sharm-el-Sheikh). But while Brazil saw some of the most compelling storytelling of any COP – with President Lula framing the Amazon as a global commons to be protected, indigenous flotillas on the river, and even the Pope pushing for concrete action – it was not enough to overcome structural blockages to progress on fossil fuels, climate finance or forests.
Emerging powers have gone from adapting to institutions to reshaping them. China, India, Brazil, and the Gulf states are no longer negotiating at the edges of a Western-designed system, but actively redesigning climate governance to reflect their strategic interests. This showed up in a desire to compartmentalise discussions on trade and emissions, and in resistance to overly prescriptive language on mitigation. Red lines will likely continue to harden as developing countries flex – especially if the US stays away from the table.
Action options for future COP presidencies
COP presidencies historically acted as conveners, focusing on the agreement text – largely with the interests of major developed countries in mind. Convening power and elegant drafting are necessary but no longer sufficient. To be successful in the new reality, COP presidencies must act as orchestrators – managing political interdependencies, sequencing issues strategically, and brokering alignment across rival blocs.
Below are four options available to Türkiye and Australia for 2026, and Ethiopia for 2027, to help set up climate negotiations for greater success:
1. Invest in the pre-work to build momentum and trust. The landmark Paris Agreement was achieved in part because ministers were engaged early and often, and expectations were disciplined. COP presidencies should engage political stakeholders throughout the 12 (or ideally, 18) months leading up to the summit and keep a tighter lid on public ambitions. They should also push countries to make good on their commitments if they are to overcome a growing sense of mistrust. This year, more than 70 new national climate plans for 2035 were still missing by the end of COP, including top-10 emitters India, Iran, and Saudi Arabia.
2. Explicitly engage with influential blocs. The COP presidency can play a much more proactive role in brokering agreements. With China, that will mean focusing on implementation (e.g., clean manufacturing, grid-scale deployment and technology diffusion) rather than rehashing mitigation targets.
With other ‘Like-Minded Developing Countries’, including India, it will mean moving from abstract calls for “ambition” toward specific packages that link mitigation to predictable finance, technology access, and transition timelines – especially in hard-to-abate sectors. And with progressives like the Beyond Oil and Gas Alliance and AOSIS, it will mean translating “climate leadership” into real economic signals, with the COP presidency pushing existing multilateral institutions to provide access to transition finance in response to ambitious climate commitments.
3. Use creative approaches, but carefully. Brazil offered a response to brittle relationships in the form of mutirão (Portuguese for “collective effort”) sessions. These included closed-door meetings, informal consultations and sidebars, typically without technical staff present, where ministers and high-level delegates could have off-the-record conversations and negotiate political trade-offs that would not survive plenary scrutiny.
Mutirão showed some promise, but its overuse at COP30 degraded transparency and highlighted a paradox in climate diplomacy that the means of identifying compromise and building consensus among some parties also damages trust with others. Future COP presidencies should be careful not to over-use mutirão itself, but instead to design other approaches that structure informal bargaining and connect it to the formal process.
This could include: making political huddles mandatory; baking in more inclusiveness by inviting fixed or rotating representatives from large coalitions (as happens in the G77 and WTO “Green Room” meetings); withholding details on the deliberations themselves but publicly communicating what issues are in scope and any red lines (akin to the forward guidance issued by central banks); and requiring closed-door sessions to feed outcomes back into open negotiating tracks (which helped rapidly translate ministerial consultations into draft text at COP21 in Paris). The combined candour and accountability of these and other approaches could help COP presidencies broker alignment among blocs with fundamentally different political economies.
4. Acknowledge climate governance is entering a post-consensus era. The assumption that all 198 parties to the UNFCCC can converge on a single, high-ambition pathway is no longer credible. Progress will increasingly depend on coalitions of the willing and plurilateral arrangements that complement the multilateral system. COP presidencies should feel comfortable speaking hard truths to power and pushing for stronger, narrower agreements than broader, weaker ones.
The challenge of climate negotiations is no longer knowing what needs to be done or how to do it, but aligning the interests, power and institutions needed to make it possible.
Responding to these dynamics requires a different kind of COP presidency – one focused less on targets and text, and more on managing real-world political priorities. Until geopolitics becomes the starting point of climate action, rather than an inconvenient backdrop, real world implementation will remain a promise deferred.

Indonesia’s nickel production cuts are not enough to create a sustainable industry
Bhima Yudhistira Adhinegara is the Executive Director of the Center of Economic and Law Studies (CELIOS), an Indonesia-based economic think tank. Muhammad Zulfikar Rakhmat is the Director of the China-Indonesia desk at CELIOS.
Indonesia produces around 60% of the world’s nickel, a metal used to manufacture batteries for electric vehicles (EVs) – more than any other country in the world. But in 2026, the government sharply reduced how much of its nickel can be extracted from the ground.
Production quotas were reduced by around 40% this year compared to 2025. Weda Bay, the largest nickel mine on Earth, had its allowance cut by more than 70% and exhausted its full-year quota by the end of May, halting mining entirely; it cannot resume large-scale extraction until next year unless regulators grant an extension.
The policy has sparked a vivid debate in Indonesian policy circles: how can the country shift its strategy from a decade of mining vast quantities of cheap nickel to producing a high-value and low-carbon material that the rest of the world wants for EV batteries.
The cuts aren’t a silver bullet to clean up Indonesia’s nickel industry, whose smelters are powered by coal – the most polluting fossil fuels. But alongside stricter enforcement of environmental rules, it is one side of efforts to produce more sustainable nickel for a premium.
Restricting Indonesia’s nickel output
Production quotas were introduced to stop the collapse of nickel prices because of oversupply in the market. Prices had fallen more than 40% in 2023 alone and kept sliding as Indonesian supply kept growing, hitting a four-year low of around $13,900 a ton in late 2025.
Critics called the recent tightening of production quotas proof that Indonesia’s nickel strategy has failed, arguing that the industry shouldn’t need to throttle its own output to survive. But when assessed against what the policy was supposed to do – push up nickel prices – it has worked. Prices jumped to $20,000 a ton in May, the highest since 2024.
Chinese industry groups representing companies that have invested billions to mine and refine the country’s nickel were furious, warning Indonesia’s president Prabowo Subianto that the cuts put $50 billion worth of investment at risk. But much of that Chinese capital is sunk into smelters and processing plants built specifically to run on Indonesian ore, and cannot simply be moved elsewhere. That gives Jakarta more room to hold its ground than the warning suggests.
Stronger environmental enforcement
Since the start of the year, Indonesia’s forestry task force has seized more than four million hectares of land from mines and plantations operating illegally in protected forests, collecting over two trillion rupiah ($113 million) in fines.
This included 148 hectares seized from Weda Bay for lacking a forestry permit. The share of nickel produced from illegal small-scale mining also fell from about a quarter in 2022 to roughly 10% by 2024.
The crackdown responds to serious environmental damages in the nickel industry. On Obi Island, a waste pond collapsed after heavy rain in June 2025, flooding three villages and killing a resident. Internal company tests found chromium-6 – a carcinogen – in the water, in quantities far above the legal limit. The footprint of another mine near Raja Ampat, which is home to some of the world’s richest coral reefs, grew 60-fold in just eight years.

The market is responding to early cleanup efforts. Low-carbon nickel now sells for a real premium, roughly $18,800 to $19,300 a ton compared with $17,900 to $18,300 otherwise, as carmakers seek to source cleaner materials to comply with the European Union’s new emissions rules for imports.
In turn, this is incentivising the industry to do more to green its operations. Vale Indonesia’s smelter in South Sulawesi now runs almost entirely on hydropower, for example.
None of this addresses coal use, however. Major Indonesian nickel producers still emitted an estimated 15 million metric tons of greenhouse gases in 2023. Indonesia may be cracking down on illegal mining and rewarding cleaner producers but it is still running its mines on the dirtiest fuel available.
Unequal benefits
For Indonesia to truly benefit from producing cleaner and high-value nickel, it needs to reap the economic benefits too. Although the industry has boosted the country’s economic growth, the reality on the ground tells a different story.
Konawe in Southeast Sulawesi is home to a major smelting complex. Growth in the district jumped from 6% to 22% between 2015 and 2023, driven almost entirely by the nickel industry, according to a study by the Lowy Institute study. At the same time, poverty levels increased slightly and unemployment remained unchanged.
In Halmahera, another epicentre of the nickel industry, spending by the poorest fifth grew just 5% between 2019 and 2022, compared with 28% for the wealthiest fifth, according to a separate study.
Part of the reason for this inequality is the system for transferring mining royalties to district authorities where the mines are located. In theory, they are entitled to the largest share. But in practice, payments are delayed, companies routinely dispute what they owe and royalties are pooled and distributed across a larger area.
The Natural Resource Governance Institute has found that decentralisation handed local governments power to approve new mines faster than they could build their capacity to manage them. Higher output raises national income on paper, but local governments remain constrained by fiscal rules and infrastructure costs that scale with mining.
None of this makes the 2026 quota cuts a mistake. Indonesia has every right to defend its pricing power over a resource it controls. But limiting extraction isn’t going to fix underlying issues around environmental enforcement and revenue-sharing. That requires rules that are consistently enforced, royalties that reach communities living by the mines, and a plan to wean smelters off coal.

Risk of “catastrophic” oil spill reaching Kimberley coast found in Woodside’s Scott Reef gas drilling plans
SYDNEY, Monday 24 August 2026 – New analysis of Woodside modelling released by Greenpeace Australia Pacific and Environs Kimberley has revealed the oil and gas corporation’s plans to drill at Scott Reef could cause an oil spill up to 30 times bigger than the 2009 Montara disaster, impacting the Kimberley coastline and reaching as far as Indonesia.
The new analysis details the “catastrophic” oil spill risk put to environmental regulators for approval by Woodside in its Browse to North West Shelf Project (Browse) plans, the worst-case scenario being a blowout directly below Scott Reef, polluting whale migratory pathways and covering isolated turtle nesting ground with oil condensate.
An FOI application (F348) revealed the federal environment department (DCCEEW) asked offshore oil and gas regulator NOPSEMA to look into the oil spill risk in 2025. NOPSEMA’s response to the application refused access to its report, and one document shows DCCEEW sought further advice this year.
Greenpeace and Environs Kimberley are calling on the Federal Government to publicly release the NOPSEMA report given the risk of an uncontrolled release of oil condensate from directly below Scott Reef.
Hannah Schuch, Senior Campaigner at Greenpeace Australia Pacific, said: “Woodside is aware that drilling at Scott Reef risks a massive oil spill that would have severe, far-reaching consequences. It appears environmental regulators are aware too.
“The state and federal governments need to take this risk from Woodside’s drilling plans seriously, as they could end up allowing the worst oil spill in Australian history.
“The pygmy blue whales that migrate up and down the WA coast with their newborns each year could be swimming and feeding in toxic, oil-slicked water. Woodside’s proposal to drill at Scott Reef is an environmental disaster waiting to happen, and the WA and federal governments have one surefire way to prevent catastrophe — reject Browse.”
Martin Prichard, Executive Director at Environs Kimberley, said: “A catastrophic oil spill by Woodside would be disastrous not just for marine life in the area but also for the Kimberley’s $500 million tourism industry.
“The state and federal governments will see five marine parks on the Kimberley coast included in the risk area of a catastrophic Woodside oil spill.
“The Montara oil spill was disastrous for West Timor with the toxic oil destroying seaweed farmers’ livelihoods. The Kimberley dodged a bullet with Montara, we were lucky the spill didn’t head our way. Myself and a crew flew over the Montara oil spill and followed it as far as we could. It was like a scene from a disaster movie.”
After the WA Environmental Protection Authority deemed Browse “unacceptable” due, in part, to oil spill risk, Woodside submitted a mitigation plan based on technology that has never been used “in anger”, a weakness stated in an independent expert review of the plan.
Professor Richard Steiner, independent oil spill expert, said: “A large offshore spill is impossible to effectively contain or recover. Historically, only 2-6% of total spill volume is recovered and the ecological injury from the release of toxic hydrocarbons in the sea can be severe, extensive, and long-term.
“Here in Alaska, government research concludes that several marine populations injured by the 1989 Exxon Valdez oil spill, including whales, fish, and seabirds, are still not recovering today, 37 years later. We should expect similar long-term ecological impacts in Western Australia if there were to be a major oil spill. The only sure way to avoid the risk of a catastrophic marine oil spill is to not develop oil and gas projects in marine environments.”

Woodside’s own modelling reveals catastrophic oil spill risk at Scott Reef
What if Australia’s worst offshore oil spill hasn’t happened yet?
I’m terrified by the thought.
Our new report in partnership with Environs Kimberley analyses Woodside’s own oil spill modelling and it reveals a worst-case blowout at the corporation’s proposed Browse gas project at Scott Reef could be up to 30 times larger than the Montara oil spill – one of Australia’s worst environmental disasters to date.
Woodside’s own modelling warns that oil pollution could spread across Scott Reef, the Kimberley coast and beyond, with impacts Woodside itself describes as “severe”, “potentially irreversible” and “catastrophic”.

What’s at stake?
Scott Reef really is like nowhere else on Earth.
Scott Reef is Australia’s largest freestanding oceanic reef, a pristine marine ecosystem that has thrived for around 15 million years. About 270 kilometres off the Kimberley coast, it supports more than 2,000 marine species, including endangered pygmy blue whales, nesting green sea turtles, the endangered dusky sea snake and ancient corals.
Yet Woodside wants to drill up to 57 toxic wells around and underneath it, causing decades of deafening seismic blasting, light and noise pollution, shipping traffic and, of course, the risk of a ‘catastrophic’ oil spill.

What did Woodside’s modelling find?
Before Browse can be approved, Woodside is required to assess what could happen if something goes wrong. We analysed the corporation’s own environmental assessment documents, and the findings are deeply concerning.
Woodside’s modelling shows that the most severe Browse scenario would be the worst oil spill in Australian history, releasing up to 893,739 barrels of condensate into the Timor Sea. For context, the Montara oil spill released 30,000 barrels of oil.
A blowout of this scale could see oil spread hundreds of kilometres, reaching some of Australia’s most important marine environments, extending into Indonesian and Timor-Leste waters and even washing up along parts of the Kimberley coast. Entrained oil – oil mixed throughout the water column – is predicted to travel up to 863 kilometres from the spill site.
The modelling identifies potential impacts to at least nine marine parks, eight reefs and three Indigenous Protected Areas, as well as important habitats for endangered species, including pygmy blue whales, green sea turtles, seabirds and other marine life.

These aren’t just places on a map. They are globally significant marine ecosystems that support ancient coral reefs, endangered wildlife, tourism, fisheries and coastal communities. A spill of this scale wouldn’t simply affect one reef; it has the potential to impact an entire connected marine ecosystem.
Why this matters now
The most important thing is that Browse has not yet been approved. That means there is still time to stop Browse and the serious risks outlined in Woodside’s own modelling.
The science has been done. The risks have been modelled. The decision now rests with the Australian Government.
Governments are often forced to respond after environmental disasters happen. This is one of those rare moments where they have the opportunity to act before one does.
What you can do
Together, we still have the power to stop Woodside and save Scott Reef.
You can help by:
- Sending an email to Environment Minister Murray Watt and Prime Minister Anthony Albanese, calling on them to reject Browse.
- Sharing this story to help more Australians understand what’s at stake.
- Encouraging your friends and family to take action.
The more people who support saving Scott Reef, the harder it is for governments to approve Woodside’s drilling plans – Browse.
Together, we can ensure a reef that has existed for millions of years is known for its incredible biodiversity – not as the site of Australia’s worst oil spill.
Let’s save Scott Reef.
