Key developments
US ocean actions cause alarm
DEEP-SEA BREACHES: US president Donald Trump signed an executive order “aimed at making it easier for companies to mine the deep seafloor”, including in international waters, according to National Public Radio. BBC News reported that the move “has been met by condemnation from China, which said it ‘violates’ international law”. In the South China Morning Post, two researchers at Nanjing University wrote that the order “will force China to act”, adding that Trump has “set the stage for heightened geopolitical tensions”. They concluded: “Should the US insist on unilateral mining, China, in collaboration with international partners, may implement maritime monitoring initiatives…[that] could document the environmental impact and breaches of standards.”
RISKY BUSINESS: Meanwhile, a Trump proclamation to loosen fishing regulations surrounding federally protected areas of the ocean – issued in mid-April – “poses major risks”, the Guardian reported. The Pacific Islands Heritage Marine national monument is home to the “most undisturbed coral reef within the US”, as well as “many threatened, endangered and depleted species”, the outlet added. Other experts said that the order – which purportedly aims to promote US fishing interests – “will negatively impact American fishers in the long run, leading to higher seafood prices for American consumers”.
OCEAN FUNDING FALLS: The 10th edition of the Our Ocean conference was held in Busan, South Korea, over 28-30 April, EFE Verde reported, where it was “attended by ministerial representatives from 100 different countries”. The newswire added that the conference would “serve as an impetus for participants to announce effective actions to accelerate the achievement of the goal of protecting 30% of the world’s oceans by 2030”. According to Mongabay, delegates to the conference announced funding commitments “totalling around $9.1bn”, but added that “this year’s numbers were the lowest since 2016”. The outlet noted that this edition was the first time the US “did not send an official delegation or make any pledges”.
Between tariffs and traceability
TARIFF-DRIVEN DEFORESTATION: US tariffs on Indonesian and Malaysian palm oil could drive up demand for soybean oil – a cheaper but more land-intensive option – and exacerbate deforestation, according to climate experts consulted by BusinessGreen. Elsewhere, Dialogue Earth reported on expectations that Brazil could expand its export of agricultural commodities to China, increasing the risk of deforestation in the South American country. Experts told the outlet that products such as soya, corn, beef and chicken could experience a surge in international demand. It added that Brazil captured a significant share of the Chinese soya market from the US during Trump’s first term.
BACKWARDS STEPS: Brazil’s supreme court ruled that Mato Grosso, the country’s biggest farming state, is allowed to withdraw tax incentives for signatories of the “soy moratorium” initiative, Reuters reported. The soy moratorium, a 2006 voluntary ban aimed at disincentivising soybean purchases from deforested areas of the Amazon, has been praised by conservationists for “slowing damage to the world’s largest rainforest”, the newswire said. However, farm lobbyists interested in increasing production are opposed to the agreement. The ruling needs to be ratified by a panel of supreme court justices before entering into force in January 2026.
COFFEE TRACEABILITY: The EU deforestation regulation has coffee farmers in Ethiopia “scrambling”, the New York Times reported. Under the new EU environmental regulation, which will enter into force at the end of the year, producers of major commodity crops will have to provide geolocation data to demonstrate that their products were not grown on recently deforested land. The outlet quoted the head of a coffee farmers’ cooperative, who said they need support to carry out the traceability of their products, adding that to do so is “very challenging and costly, and we don’t have any help”.
Spotlight
The climate uncertainties for west Africa’s fishers
This week, Carbon Brief unpacks three key takeaways from a recent report, published by the Salata Institute for Climate and Sustainability, on the sustainability of west African fisheries.
In west Africa, coastal fishing communities underpin a large proportion of the region’s economies and traditional ways of life.
Their number has only increased in recent years as a result of population growth and migration, driven by economic opportunity – even as fishers have faced declining catches.
A new report detailed the challenges facing the Gulf of Guinea’s fisherfolk amid a warming climate, as well as offering insight into what the future of the fishery could look like.
Here, Carbon Brief unpacked three key messages from the report.
1. Key fish catches have declined dramatically since the 1990s.
The report identified three major factors that have contributed to the decline of fish stocks in the Gulf of Guinea: climate-change-driven ocean warming, illegal fishing by industrial Chinese trawling ships and overfishing by fisherfolk using traditional methods.
According to the report, sea surface temperatures along the Ghanaian coast have increased at a rate of 0.011C annually since the 1960s – and could increase by another 1.6C by the end of the century under a high-emissions scenario. This warming is driving “significant geographic shifts” in the range of the species targeted by west Africa’s fisherfolk, the report said.
The report also identified other climate-driven threats to fishers, such as sea level rise, deoxygenation of ocean waters and beach erosion.
As a result of dwindling numbers, catches have fallen significantly – in some cases, by more than 50% – since the early 1990s “despite an increased number of workdays spent fishing, evidence of an underlying stock collapse”, the report warned.
Even under good fisheries management in the future, the report warned that the maximum catch potential will continue to decline due to warming.
2. Current management strategies are not sufficient to allow fish stocks to recover.
The climate pressures on the Gulf of Guinea fish stocks are compounded by overfishing from two main sources – industrial trawling ships, predominantly from China, and an increasing number of artisanal fisherfolk using improved equipment, such as outboard motors.
Ghana’s artisanal fishing fleet has grown from around 8,000 canoes in 1990 to more than 12,000 in 2022. Previous research has estimated that this fleet lands up to 70% of the small fish taken in the country. The report did not mince words:
“They clearly contribute to overfishing.”
Both Ghana and neighbouring Ivory Coast have implemented “closed seasons” during peak spawning months in an attempt to allow the fish populations to recover, but the policies “have produced disappointing results so far”, the report noted. It said:
“To be technically effective in rebuilding fish stocks, the closed seasons should have begun prior to 2016, before spawning stock biomass had been so badly harmed.”
3. Diversifying income will be key for adapting these communities to climate change.
The researchers surveyed fishing communities in Ghana, Ivory Coast and Nigeria that relied on fishing for “nearly all” of their livelihoods. Most of the individuals identified a decrease in catch over the preceding years.
A large majority of respondents answered “no” when asked if their children would be able to make a living off fishing or fishing-related activities.
The researchers then evaluated programmes in Ghana, undertaken alongside the US Agency for International Development, that were focused on helping fishing households diversify their income. The weekly earnings “were far from a full replacement for fishing income, but to a varying extent they did provide a useful supplement”, the authors wrote.
However, funding for these programmes was cancelled by the Trump administration in its attempt to dismantle USAID in early 2025. The report added:
“Finding substitute funding…will be difficult.”
News and views
CONSERVATION REFORM: The Washington Post editorial board called for “reforming” the US Endangered Species Act “to better incentivise citizens to protect the country’s precious biodiversity”, amid Trump’s attempted weakening of the landmark law. It argued for “giving landowners financial incentives to assist in conservation efforts” – similar to existing subsidy programmes from the US agriculture department. The editorial said: “The scale of the threats to biodiversity…makes it essential to expand federal conservation strategy beyond punitive measures.”
IMPORT IMBALANCE: Amid growing US-China tensions, top Chinese policymakers “said the country could do without American farm and energy imports”, according to the Financial Times. China’s state planner, Zhao Chenxin, “said domestic farm and energy production, along with imports from non-US sources, would be more than enough to satisfy demand”, the outlet reported. At the same time, the FT said, the “loss of the Chinese market would be a substantial hit for US farmers”. It added: “China has shown little appetite for negotiations and repeatedly blasted Washington’s claims of ongoing discussions as false.”
WAYWARD WHALES: Australia’s whale-watching season “started early” this year, according to the Sydney Morning Herald, which said the early migration was a “possible sign of stress from climate change”. A population of humpback whales migrates from Antarctica to Australia at the end of the southern hemisphere summer in “one of the longest migrations of any mammal”, the outlet said. The newspaper cited Dr Olaf Meynecke, a research fellow at Australia’s Griffith University, who explained that the “earlier migration was probably because record-low sea ice reduced krill numbers, making it harder for whales to find food”.
COFFEE GOES UP: The Associated Press reported that coffee prices have remained high due to drought and heat last year that impacted production in Brazil and Vietnam, the world’s largest coffee growers. US tariffs on coffee-producing countries “are expected to drive up costs for Americans”, the newswire added. Elsewhere, extreme weather conditions, such as drought and tropical cyclones, have affected major coconut-growing countries, with the Philippines’ output expected to decline by 20%, Bloomberg reported.
OFFSET OPPOSITION: Inhabitants of the Kajiado county, in Kenya, clashed over a carbon-offsetting initiative that would have set up a 40-year land lease deal, the Daily Nation reported. The project involved leasing 168,000 acres of the community’s ancestral land in return for “promis[ed] financial benefits”. Opponents of the deal said they were “misled and misinformed about the whole process”, but the community’s chair “dismissed the allegations of fraud or coercion”. The final signing of the deal was “postponed indefinitely”, as the two sides could not come to an agreement.
INCOMPLETE ACCOUNTING: Science Feedback questioned a recent study, published in Environmental Research Letters and covered in the media, that claimed agriculture is the largest greenhouse gas-emitting sector. According to climate scientists consulted by the outlet, while methane emissions from agriculture and fossil fuels are comparable, fossil fuels have a greater impact on CO2 emissions. Prof Pierre Friedlingstein, a climate scientist at the University of Exeter, told the outlet that the paper only considered gross emissions, not factoring in the carbon sequestration that occurs in agriculture.
Watch, read, listen
ATTENBOROUGH’S OCEAN: BBC News covered Sir David Attenborough’s new documentary, which chronicles the Earth’s oceans.
SIGHTING BIRDS: The New York Times chronicled a bird-watching trip to the Panama Canal, home to a thousand native and migratory birds.
WHALE SONGS: A Mongabay podcast interviewed biological oceanographer Dr John Ryan, who explained why listening to whales’ songs is important for their conservation.
FORESTS MONITORING: A short video by France24 featured the European Space Agency’s new satellite, which is aimed at monitoring the world’s forests.
New science
- Research published in Nature Ecology & Evolution found that there is no “one-size-fits-all” approach to preserving biodiversity amid growing agriculture. The scientists found that neither agricultural expansion and intensification “consistently benefits biodiversity” and urged a “context-dependent balance” between the two.
- Intense tropical cyclones may pose an extinction risk to organisms living on five island chains that are biodiversity hotspots, a Biological Conservation study found. The researchers tracked the trajectory and frequency of severe tropical cyclones over the last 50 years and used the IUCN red list to identify species at risk.
- Another Nature Ecology and Evolution study found that implementing strategic restoration measures – such as those outlined in the EU nature restoration law – could improve the conservation status of more than 20% of endangered species and increase carbon sequestration.

Cropped 7 May 2025: Ocean alarm; Tariff deforestation risk; West Africa’s fisheries
As COP30 reaches its midway point in the Brazilian city of Belém, Carbon Brief has hosted its second “ask us anything” webinar to exclusively answer questions submitted by holders of the Insider Pass.
The webinar kicked off with an overview of where the negotiations are on Day 8, plus what it was like to be among the 70,000-strong “people’s march” on Saturday.
At present, there are 44 agreed texts at COP30, with many negotiating streams remaining highly contested, as shown by Carbon Brief’s live text tracker.
Topics discussed during the webinar included the potential of a “cover text” at COP30, plus updates on negotiations such as the global goal on adaptation and the just-transition work programme.
Journalists also answered questions on the potential for a “fossil-fuel phaseout roadmap”, the impact of finance – including the Baku to Belém roadmap, which was released the week before COP30 – and Article 6.
The webinar was moderated by Carbon Brief’s director and editor, Leo Hickman, and featured six of our journalists – half of them on the ground in Belém – covering all elements of the summit:
- Dr Simon Evans – deputy editor and senior policy editor
- Daisy Dunne – associate editor
- Josh Gabbatiss – policy correspondent
- Orla Dwyer – food, land and nature reporter
- Aruna Chandrasekhar – land, food systems and nature journalist
- Molly Lempriere – policy section editor
A recording of the webinar (below) is now available to watch on YouTube.

A sobering truth hangs over the COP30 climate talks in Belém: negotiators are discussing adaptation indicators with the enthusiasm of technocrats while quietly starving frontline communities of the resources they need to survive.
The UN’s latest adaptation gap report could not be clearer. Needs are skyrocketing. Finance is collapsing. And yet the global community continues to debate how to measure progress, rather than how to enable it. They act as if weighing a cow will make it fatter, rather than giving it any food.
This contradiction exposes the heart of the climate crisis: adaptation is not merely a technical challenge; it is a political and moral one. Every finance gap is a justice gap. Behind every unmet target are farmers who cannot plant, families who cannot rebuild, and communities forced into displacement because “resilience” was promised but never delivered.
Adaptation is the difference between dignity and despair. It determines whether societies can endure rising temperatures, intensifying floods, or prolonged droughts — or whether they are pushed beyond the limits of survival.
Yet, as negotiators haggle over the Global Goal on Adaptation (GGA) and its indicators, the foundations needed to achieve these goals are crumbling. How do we talk about climate-resilient development when the means to achieve it are drying up? How do we measure resilience while draining the very resources that make resilience possible?

COP30 Bulletin Day 5: COP30 could greenlight work on a fossil fuel transition roadmap

COP30 Bulletin Day 6: First week ends with a colourful march and much work left to do
UN climate chief Simon Stiell tells governments “to give a little to get a lot”, as many thorny issues remain for ministers to resolve next week
At COP30, countries must resist the impulse to rush through a weak indicator framework simply to claim progress. This would give us a system that measures activity, not impact. – that measures paperwork, not protection.
Africa is championing a fit for purpose GGA, but some have misunderstood and wrongly accused it of stalling the GGA process. But Africa is not delaying adaptation work. Africa is living adaptation every day. For us, adaptation is not a choice or a policy preference or an interesting side issue. It is an existential threat that is already reshaping livelihoods, economies, and ecosystems.
Africa needs this COP to get the GGA right. What we reject is an approach that turns adaptation into an exercise in reporting rather than a vehicle for survival.
A meaningful GGA must track whether finance actually reaches those who need it, whether technologies are shared equitably, and whether vulnerable countries are being supported to build early-warning systems, climate-resilient infrastructure, water security, and heat-resilient health systems. Without this backbone of finance and technology-sharing by the rich world, adaptation indicators become little more than an empty checklist.
And this is where COP30 stands at a crossroads. If rich countries succeed in pushing through a set of indicators that sideline finance, it will confirm that the world’s poorest are once again being asked to run a race with no shoes. No community can adapt without resources. No farmer can withstand worsening heatwaves without irrigation and drought-resistant seeds. No coastal town can protect its people without early-warning systems and resilient infrastructure. To pretend otherwise is not merely flawed policy; it is a profound injustice.

Global South’s climate adaptation bill to top $300 billion a year by 2035: UN
Warning over massive shortfall in climate adaptation funding comes days before COP30 in Brazil, where the issue is set to be a major theme
Some will argue that indicators and finance should remain separate discussions. But this is a fiction. You cannot track progress on adaptation without the means to adapt. Adaptation is where political decisions determine whether people live safely or suffer needlessly.
The world is not short of evidence of this suffering, it is short of political courage. Extreme weather displaces more than 30 million people a year, with Africa bearing the brunt. While communities rebuild with scarce resources, developed countries continue to cut aid or repackage support as loans which shackles poor countries with eye-watering debt. This does not build resilience — it entrenches vulnerability.
The Global Goal on Adaptation will become a white elephant if it is not paired with predictable, grant-based finance. Indicators that pretend adaptation is happening without resourcing it will fail the people they claim to protect. COP30 is the moment to close the distance between science and solidarity: wealthy nations must scale up adaptation finance, share technologies, and support long-term resilience planning.
Until then, the world’s most vulnerable will continue carrying the heaviest burden with the lightest support — a defining injustice of our time.

Global Goal on Adaptation: Weighing the cow won’t make it fatter
Last Monday, to get the COP30 agenda agreed, Brazil promised to hold consultations on four controversial issues: emissions-cutting, transparency, trade and finance. Last night, after most delegates had spent their day off exploring the Amazon, the Presidency released a five-page document summarising what was said in those consultations.
Nothing in that “summary note” has been agreed by countries. But it collects together divergent views and forms the basis of what could become a politically agreed statement (known in the jargon as a cover decision) at the end of the COP. It has three key strands on boosting climate finance, strengthening emissions reductions and tackling trade measures linked to decarbonisation.
It includes the key rhetorical messages the COP30 presidency wants to include – that this is a “COP of Truth”, multilateralism is alive (despite President Trump’s efforts to thwart climate action) and the Paris Agreement is now moving from negotiation to implementation.
On emissions-cutting and the need to raise ambition – sorely lacking after the latest round of national climate plans (NDCs) – the note includes an option to hold an annual review and explore the “opportunities, barriers and enablers” to achieve the global efforts agreed at COP28 in Dubai to triple renewable energy and double energy efficiency by 2030; accelerate action to transition away from fossil fuels; and halt and reverse deforestation. This is essentially where any reference to a roadmap to transition away from fossil fuels could be anchored.

COP30 Bulletin Day 5: COP30 could greenlight work on a fossil fuel transition roadmap

COP30 Bulletin Day 6: First week ends with a colourful march and much work left to do
UN climate chief Simon Stiell tells governments “to give a little to get a lot”, as many thorny issues remain for ministers to resolve next week
The document also includes proposals to “urge” developed nations to include finance in their NDC climate plans and “encourage” all countries that have set a range of percentage emissions reductions in their NDCs – like the EU’s 66.25-72.5% – to move toward the upper end of the range.
On finance, options include a three-year work programme on provision of finance by wealthy governments and a goal to triple adaptation finance (something the least-developed countries are pushing for) or just repeating the finance goal agreed at COP29 and “noting” a new roadmap to achieve that (which rich nations very much prefer).
There are also various options for how to talk about where climate and trade overlap: an annual dialogue, roundtables, consultations, a new platform or just to keep discussing in the ‘response measures’ strand of climate talks.
Li Shuo, head of the Asia Society Policy Institute’s China Climate Hub, told Climate Home News it was highly significant that – after two years of the issue being buried in climate talks – trade has now been “anchored in the endgame of this COP”.
The various potential outcomes in the summary note could be included in existing agenda items or they could be lumped together into what is usually referred to as a cover text but the Brazilian government would likely prefer to call a “mutirão decision” or a delivery, response or global action plan.
Essentially, after governments ignored the presidency’s pleas not to add contentious items to the agenda, it looks like they could get at least some of what they want by turning those issues into the headline deal from COP30 .
At the start of the high-level segment of the conference on Monday morning, where environment ministers deliver their speeches, UN climate chief Simon Stiell urged governments “to get to the hardest issues fast”.
“When these issues get pushed deep into extra time, everybody loses. We absolutely cannot afford to waste time on tactical delays or stone-walling,” he added.
The presidency consultations on the issues in the note will continue on Monday, along with negotiations on adaptation metrics and a Just Transition Work Programme among others. The COP30 president then plans to convene a “Mutirao” meeting of ministers and heads of delegation on Tuesday “to bring together various outcomes”.
Korea joins coal phase-out coalition at COP30
As fossil fuels have grabbed headlines at COP30, major coal producer South Korea kicked off the second week of the Belém conference with an actual concrete pledge: the country will phase out most of its coal power by 2040.
Operating the seventh-largest coal fleet in the world, Korea announced on Monday that it will join the Powering Past Coal Alliance (PPCA), an initiative launched in 2017 by the UK and Canada to encourage countries to wean themselves off the planet’s largest source of emissions. Oil and gas exporter Bahrain is another new member.
Asian industrial giant Korea said that out of 62 operating coal power plants, it will commit to retiring 40 of them by 2040. The phase-out date of the remaining 22 plants “will be determined based on economic and environmental feasibility”.
Korean Minister of Environment Kim Sung-Hwan said at an event announcing the pledge that the country will play a “leading role” in the energy transition.
“South Korea is known as a manufacturing powerhouse. Unfortunately renewable energy has taken a low share in our power mix, but going forward we are determined to foster renewable energy industries,” he told journalists. “We will show the world that we can create a decarbonised energy transition.”
Asked about a fossil fuel transition roadmap – an idea floated around by many governments in Belém – Sung-Hwan said “humanity and all of the governments should work together to achieve a decarbonised green transition”, adding that “COP30 will be an important momentum”.
UK climate minister Katie White said Korea was taking an “ambitious step”, and that they can “reap the rewards that we are seeing from our own clean energy transition”.
Korea is a major importer of oil and gas. Domestically, it has historically relied on coal for electricity, but the country’s production of the fossil fuel has decreased steadily by 86% in the last 25 years, according to the International Energy Agency (IEA). Their nuclear fleet, on the other hand, has nearly doubled in the same time period.
