Welcome to Carbon Brief’s DeBriefed.
An essential guide to the week’s key developments relating to climate change.

This week

Finance and 1.5C dominate talks

AGENDA ADOPTED: Negotiations at the COP30 UN climate talks began in the Brazilian city of Belém this week, attended in person by Carbon Brief’s Daisy Dunne, Josh Gabbatiss and Anika Patel. The Brazilian hosts scored an unexpected early win by dodging an “agenda fight” over proposals to add various contentious issues to the official docket. Despite the neat footwork, four issues kept off the agreed agenda – climate finance; emissions reporting; trade measures; ambition and 1.5C – still loom large, having merely been diverted into “presidency consultations”.

PRESIDENCY PROMISES: By Wednesday, the presidency was promising “good news” at a plenary later that day, which had been due to offer an update on progress with the four extra items. Instead, it ended abruptly, with COP30 president André Corrêa do Lago promising to say more at another plenary scheduled for tomorrow. It remains unclear how the presidency intends to deal with these thorny issues, leaving the COP rumour-mill in full swing.

MINISTERIAL MAGIC: Aside from the extra issues, the official agenda at COP30 already has more than 100 items to contend with, including how to track progress on adaptation and how to ensure a “just transition” as emissions-cutting measures are implemented. (You can follow them all via the Carbon Brief text tracker.) While draft texts have started to emerge, many items remain stalled, with persistent divisions along familiar lines (see below). Negotiators will be hoping that ministers arriving over the weekend are primed to unlock progress. Brazil has appointed pairs of these politicians to push for deals in key areas.

Around the world

  • Ethiopia has said it will host COP32 after beating out a bid from Nigeria, Reuters reported. Turkey and Australia are still in deadlock over who should host COP31, with a decision due by the end of these talks, BBC News reported. 
  • China will not contribute to Brazil’s Tropical Forest Forever Facility, Bloomberg reported, while Devex said two multilateral development banks are considering paying in. More than $5.5bn has been pledged so far, which BusinessGreen noted is “well short” of a $25bn target. The fund was labelled a “false solution” by some Indigenous and civil society groups.
  • After Brazilian president Luiz Inácio Lula da Silva called for a “roadmap” away from fossil fuels ahead of COP’s opening, rumours are swirling over how this might take shape. A new declaration spearheaded by Colombia and a roadmap with backing from a number of countries, including Denmark, the UK, France, Kenya and Germany, are being floated as possible options.
  • China is currently among the countries pushing for “provision of finance from rich countries and unilateral trade measures” to be included on the agenda, reported Climate Home News. Chinese delegation head Li Gao told Agence France-Presse it is “crucial” for developed countries to fulfil their $300bn commitment.
  • Dozens of Indigenous protesters forced their way into COP’s blue zone on Tuesday night, expressing anger at a lack of access to the negotiations, Reuters said. On Friday, a peaceful protest blocked the entrance to the blue zone, causing lengthy queues as delegates were forced to use a side door.

Captured

China’s carbon dioxide emissions have “now been flat or falling for 18 months” since March 2024, analysis for Carbon Brief has found, due, in particular, to the transport, cement and steel sectors. The analysis has been covered widely in publications including China’s Global Times, the New York Times, Financial Times, Reuters, Bloomberg and on the frontpage of the Guardian.

Spotlight

What to expect from COP30 talks

This week, Carbon Brief’s expert team walk through what is happening with the biggest issues being negotiated at COP30.

‘Cover text’

Can you judge a COP by its cover text? At COP, the presidency has the option to pull together a new negotiated “cover text”​​, an overarching political overview of decisions agreed at the summit, along with other issues not on the agenda that it wants to draw attention to.

COP30 president André Corrêa do Lago might have dismissed a catch-all “cover decision” as a “last-minute solution” ahead of COP and dodged the question since, but other parties have been less shy in hinting that a cover text is, indeed, coming.

Cover decisions are often the product of fraught negotiations, high stakes, too little time and too many parties to accommodate.

This year, there is added pressure to address what is happening in the wider world outside the “negotiations” and to politically signal that the UN climate process is alive and making progress, despite the withdrawal of the US.

What elements could go into it? As a member of the “BASIC” group of nations comprising Brazil, South Africa, India and China, trade measures could find a place. But ideas pushed by Brazilian president Lula for new “roadmaps” away from fossil fuels and deforestation might find a place. Finance, however, could be much trickier to fit in.

Adaptation

One of the key expected outcomes of COP30 is agreement on a list of 100 indicators that can be used to measure progress under the “global goal on adaptation” (GGA). After two years of work by experts, negotiations got underway with a suggested list that had been whittled down from nearly 10,000 possible indicators.

Despite the focus on the GGA by the COP30 presidency and others, division has quickly emerged around the timeline for the adoption of the indicators. The African Group has notably requested a two-year work programme to further refine the list, while other parties are pushing for the indicators to be adopted in Belém as planned.

On Wednesday, an informal note was published that compiled elements for a draft decision. Significantly, for the first time under the GGA, this included a call for developed countries to “at least triple their collective provision” of adaptation finance by 2030, with a target to reach $120bn. This echoed a suggested target originally set out by the negotiating group of least developed countries (LDCs), supported by the African Group, Arab Group and the Association of Latin America and the Caribbean (AILAC) countries.

Just transition and mitigation work programmes

Over the past year, civil society groups have been calling for the establishment of a mechanism to enact the agreed UNFCCC principles of a “just transition”. This gained momentum on Wednesday within negotiations of the just transition work programme (JTWP), when the G77 and China called for the development of the “Belem Action Mechanism” (BAM).

Chile, the Alliance of Small Island States (AOSIS), India and other developing countries supported the mechanism. However, Norway, the UK, Australia and Japan pushed back. Other long-standing points of contention have also raised their heads, including around unilateral trade measures and references to fossil fuels and aligning to global temperature goals.

Within the mitigation work programme (MWP) talks, negotiators are looking to build on two dialogues held this year. The main themes at COP30 are the links between the MWP and the global stocktake (see below) and the future of the programme itself.

Old divisions have emerged in negotiations, focused predominantly on the mandate of the MWP and the potential development of a digital platform as part of its continuation.

UAE dialogue

The landmark outcome of the first “global stocktake”, agreed at COP28 in Dubai, called on all countries to contribute to a “transition away from fossil fuels”. It also mandated a “UAE dialogue” on “implementing the global stocktake outcomes”.

Two years later, countries remain deadlocked over what this dialogue should discuss. Many want it to cover all parts of the stocktake, including the energy transition, while others want an exclusive focus on climate finance. They also disagree on whether the dialogue should have substantive outcomes, including a formal process to keep discussing the issues raised.

Having failed to reach agreement at COP29 last year, the latest draft text shows parties are just as far apart in Belém, nearly halfway into the summit.

Finance

Climate finance for developing countries does not occupy a high-profile position in the formal COP30 negotiations. Yet, as demonstrated by its role in adaptation talks and the agenda dispute, finance still has the potential to derail proceedings.

Ahead of the conference, the COP30 and COP29 presidencies released their “Baku to Belém roadmap”, exploring how finance could be ramped up to $1.3tn by 2035.

An influential group of experts also released new analysis showing a “feasible path” to this goal, leaning on private finance. They said this work would provide a “valuable signal” to those in the finance sector.

However, with no position in the Belém negotiations, it was unclear how – or whether – the roadmap would be taken forward by governments beyond COP30.

Instead, finance negotiators have been occupied with technical matters, but these still show signs of division. For example, some developing-party groups have pushed back against an EU priority goal to extend a “dialogue” about “making finance flows consistent” with climate objectives.

Planned offshore oil and gas expansion threatens key marine ecosystems, report

Published

June 5, 2026

By

Ocean and coastal creatures are being put at risk by the spills, noise, dredging and shipping associated with new offshore oil and gas infrastructure, says a new report by a group of environmental NGOs.

The report by a group of twelve environmental groups analysed planned new offshore oil and gas blocks covering 430,000 square kilometres – an area the size of Sweden – in 11 countries.

Blocks in countries such as Kenya, Indonesia and Australia overlap with some of the planet’s hotspots for marine biodiversity, home to mangroves, coral reefs, sea turtles, sharks and whales.

Oil and gas expansion is advancing in spite of the legal protections already in place, the report says, with a third of the area being licensed overlapping with marine and coastal protected areas.

    “It is alarming to see the research findings and the sheer scale of fossil fuel expansion trajectories threatening the health and future of our shared ocean,” said Tyson Miller, Executive Director of Earth Insight, one of the environmental NGOs involved in the report.

    At the first conference on Transitioning Away from Fossil Fuels in Santa Marta, around 60 countries floated the idea of creating “fossil-fuel-free zones”, which would seek to place limits on coal, oil and gas in areas where development would lead to severe social and environmental harm.

    As part of the landmark Kunming-Montreal biodiversity deal, governments have also pledged to protect 30% of the planet’s land and marine ecosystems by 2030. This could be used as an opportunity to limit oil and gas expansion in sensitive areas, Miller said.

    The report says the findings “reinforce the need for governments, financial institutions and companies to stop funding and supporting offshore oil and gas expansion”, and calls for the creation of fossil-fuel-free zones in “high-value marine and coastal areas”.

    Oil bidding in biodiversity hotspots

    As one of the case studies, Kenya — which is set to host the Our Ocean Conference in Mombasa later this month — has opened 50 offshore oil and gas blocks for bidding in the Lamu Basin, one of East Africa’s marine biodiversity hotspots.

    These blocks overlap with all the region’s mangroves and coral reefs, the report says, which provide nursery habitats for fish, sea turtles and the vulnerable dugong.

    These ecosystems are already under severe stress from climate change-related ocean heating and increased water acidity and could now face seismic surveys, offshore drilling, dredging, increased shipping traffic, oil spills, chemical discharge and underwater noise pollution.

    The government estimates that oil production will start by 2026, aligning with “global best practices”, and has said the Lamu basin has vast “untapped potential”. The country is expected to open bidding for the first 10 blocks by September.

    Muturi wa Kamau, network coordinator for the Kenya Oil and Gas Working Group, said in a statement that the country “is preparing to open ecologically sensitive areas for fossil fuel exploration” while positioning itself as a leader in ocean diplomacy.

    “The question is: at what cost are we willing to risk these fragile ecosystems and the livelihoods of coastal communities who have depended on them for generations?” Kamau said.

    Australia’s Otway Basin

    After a four-year pause, Australia — which will act as co-presidency of the COP31 climate summit — resumed offshore exploration in the Otway basin last year, with American energy firm ConocoPhillips among the operators approved for exploratory drilling off the country’s southern coast.

    The sites under exploration are as close as one kilometre from a series of marine reserves known as sanctuaries for pygmy blue whales, who travel thousands of kilometres to reproduce in those waters. Orange roughy, a deep-sea fish that can live for over 140 years, may also be harmed.

    In total, the report analysed new LNG export projects in Argentina, Alaska, Mexico and Tanzania, as well as expanded offshore oil and gas licensing in Australia, Cameroon, Indonesia, Jamaica, Kenya, Norway, and Trinidad and Tobago.

    The scramble to stockpile critical minerals could drive up energy transition costs

    Published

    June 5, 2026

    By

    As competition for minerals needed to produce clean energy technologies intensifies, a growing number of countries have resorted to an age-old mechanism to cope with the threat of scarcity: stockpiling.

    The world’s biggest economies are racing to shore up reserves of cobalt, lithium, graphite and rare earths, which are needed to produce batteries, electric vehicles, wind turbines and electric systems to wean the global economy off fossil fuels. The same minerals are also increasingly sought after to manufacture military hardware and chips for AI, adding further pressure on supplies.

    But the cutthroat scramble to build up reserves threatens to drive up the costs of the energy transition by intensifying competition and pushing up prices of key materials needed to produce clean energy technologies, research published today has found.

    “If you undermine the financial viability of [clean energy] projects through higher raw material costs, you’re going to delay their roll-out,” co-author Hugh Miller, the critical minerals lead at the Centre for Economic Transition Expertise at the London School of Economics and Political Science, told Climate Home News.

    Stockpiling “is happening, whether we like it or not”, said Miller. “But if we’re going to do it, we need to have it in a coordinated manner that means we don’t have massive market volatility and adverse implications from every country trying to go at it alone,” he added.

    The rise of stockpiles

    A growing number of governments have adopted national stockpiling programmes in response to heightened geopolitical tensions around mineral supply chains.

    Earlier this year, US President Donald Trump announced the establishment of a critical mineral reserve known as “Project Vault” to protect American businesses from shortages after China imposed export restrictions on rare earth supplies.

    Beijing suspended the measures until November as part of a trade truce with Washington but the episode spooked Western governments and exposed how strategic materials can be weaponised to achieve geopolitical objectives.

    Australia, China, the EU and India have also announced measures to create strategic mineral reserves. Japan and South Korea already have long-standing mineral stockpiling programmes.

    “Legitimate concerns”

    “There are legitimate concerns with regards to potential global shortages of these minerals,” said Miller, citing rapidly rising and concurrent mineral demand for the energy transition, AI, data centres, and military technologies, combined with underinvestment in new supplies for some minerals, such as copper.

    While stockpiling can serve as an emergency response mechanism during acute shortages, it does nothing to address the underlying concentration risks in mineral supply chains. The Democratic Republic of Congo holds around 70% of the world’s cobalt reserves, for example, while China dominates the processing of 19 out of 20 minerals deemed critical by a large number of nations.

      Uncoordinated stockpiling programmes risk heightening the price volatility they are designed to hedge against, according to the report.

      Researchers found that if Australia, China, the EU, India, Japan, South Korea and the US simultaneously built reserves of minerals to cover six months of imports, the aggregate stockpile demand could represent up to 34% of global annual cobalt supply and over 10% of global lithium, graphite and copper supply. That could cause a shock to the market, triggering the shortages and price spikes they are trying to avoid.

      Miller said it was unlikely that every country would stockpile at that rate, but aggregate stockpiling demand of just 5% of global mineral supply would have an impact on prices.

      Coordinating stockpiles: a role for the IEA?

      Researchers found that avoiding the negative impacts of stockpiling requires global coordination over how mineral stocks are accumulated and released – a mechanism which already exists for other commodities, including oil.

      Coordination should include agreed rules for countries to build up their stocks over a slow and staggered timeline and pre-agreed conditions for releasing reserves to provide market predictability and reduce the risk of price spikes.

      The International Energy Agency (IEA), which was established after the 1970s oil crisis to coordinate emergency oil stock releases among member countries, is best placed to oversee such a mechanism, they say.

      Earlier this year, IEA member countries called on the agency to strengthen its work on critical minerals, including by providing support to countries “that choose to establish and expand critical minerals stockpiling systems”.

      But Miller and his co-author Pau Morandi, a policy fellow at the Centre for Economic Transition Expertise, argue that members should go one step further and mandate the IEA to coordinate the security of supplies, rather than only helping individual governments.

      The IEA has been contacted for comment.

      A call to action for the G7

      Miller said he hoped the research could be picked up by the G7 group of wealthy countries, which could lead on mandating the IEA to take on this coordination role.

      France, which is presiding over the group this year and is hosting leaders in Evian on the shores of Lake Geneva in mid-June, has made strengthening the resilience of critical minerals value chains a priority.

      In a communique last month, finance ministers agreed to “deepen and expand our cooperation among G7 members and with like-minded partners” to strengthen and diversify critical mineral supply chains and to continue discussions “on how to best organise analytical cooperation”.

      Sebastien Treyer, executive director of the Paris-based Institute for Sustainable Development and International Relations (IDDRI), said he hoped the G7 leaders’ summit can help move the discussion on critical minerals towards greater international cooperation to secure the resources the world needs to build a clean economy.

      From inclusive and mutually beneficial partnerships to mine resources to stockpiling minerals, “we need to coordinate more like a trade organisation than something that is about securing supply,” he said.
