The COP30 climate summit in Belém will put adaptation to a warming world front and centre, with the aim of moving negotiations from technical debate to deciding how to measure adaptation progress and accelerating action on the ground, according to Alice Amorim, Brazil’s COP30 programme director.
At the mid-year UN talks in Bonn, countries reached a compromise on work to select a set of 100 indicators this year for the Global Goal on Adaptation (GGA), which is part of the Paris Agreement.
But a key sticking point has been how to track funding for vulnerable communities to become more resilient to climate shifts – which affect everything from agriculture to water and infrastructure – in a way that can help ensure that developed countries are providing adequate support to developing nations.
IEA says some oil and gas projects must shut early to meet 1.5C limit
A meeting of technical experts in late August narrowed down the list of GGA indicators to 113, but was unable to agree on how to monitor finance for adaptation, according to a summary released this week.
With the negotiations set to continue at COP30, Amorim told this month’s Africa Climate Summit in Addis Ababa that she hopes countries will finally agree on the indicators in Belém, adding that the Brazil conference – being described as an “implementation COP” – must go further to shape a system that can quickly turn those decisions into real-world results.
“This is a moment where we don’t need to wait anymore for all parties to agree on what needs to happen to make adaptation finance flow to Africa, to Latin America, to the small island states and so on. It’s about acting upon it, it’s about moving from commitments to practice,” Amorim said.
She added that there should be no more delay in investing in adaptation and resilience-building because resources are needed urgently to build climate-safe infrastructure and implement national adaptation plans.
COP30 will not launch “shiny new initiatives”, she added, but will bring existing solutions “to understand what is already happening on the ground that needs to be leveraged and what are the gaps that financial sector players and policy makers need to address”.
An existing goal to double adaptation finance to around $40 billion a year by 2025 – agreed at COP26 – expires this year, and experts say it has helped drive more money into adaptation.
The Least Developed Countries group has called for a new goal of tripling finance from 2022 levels by 2030 to close to $100 billion a year. But even that would not close the gap which the UN estimates to be $160 billion-$340 billion a year by 2030.
Addis summit gets behind adaptation
Brazil’s Amorim told the Africa climate summit in Ethiopia last week that the need for adaptation “is clear and tangible” on the continent. What is missing, however, are the conditions to drive it in a much wider and faster way, she added.
Adapting to climate change by shoring up defences against negative impacts such as extreme heat, floods and food insecurity remains a priority for African countries. Leaders at the summit made it clear in their final declaration – yet to be published – that the continent needs scaled-up, grant-based and concessional finance for adaptation, whose delivery should avoid loading countries with more debt.
Since 2017, most adaptation finance flows to the continent have come as loans, with little private sector investment, raising fears over rising debt burdens on the continent. While Africa needs about $70 billion annually for adaptation, it received only $14.8 billion in 2023, according to an analysis by the Global Center on Adaptation (GCA) and Climate Policy Initiative (CPI) released during the summit.
The analysis showed that since most adaptation finance comes from international public sources such as donor governments and multilateral development banks, cuts in bilateral aid mean capital flows to sub-Saharan Africa are projected to decline in 2025.
“Public health emergency”: Report shows fossil fuel impacts on every stage of life
Reacting to the report’s findings, Macky Sall, former president of Senegal and chair of the GCA, said the aid cuts from major donor countries would be “unprecedented – and unacceptable – precisely when resilience spending must rise”.
To enable African countries to build resilient infrastructure without piling on unsustainable debt, Sall called on developed-country partners “to reverse planned reductions, ring-fence adaptation within aid budgets, and expand guarantees and local-currency facilities”.
Tadeous Chifamba, permanent secretary of environment, climate and wildlife in Zimbabwe, said COP30 should focus attention on increasing adaptation finance flows to Africa, drive a restructuring of the global financial architecture and ensure developed countries, which are responsible for historical emissions, play their part in mobilising funds for adaptation.
“It has become a moral obligation on their part to ensure that there is fairness, justice and that they assume responsibility just as we are doing as the first-line defenders,” Chifamba told an event on the sidelines of the Addis summit.
Mobilising African money too
While African leaders need developed countries to help deliver finance for adaptation, they made it clear at the summit that the continent is not asking for charity, but is championing local solutions and will also mobilise resources from African financial institutions to respond to climate shocks.
At the summit, the second phase of the Africa-led Adaptation Acceleration Program (AAAP)- a joint initiative of the African Development Bank and the GCA – was launched with a goal to mobilise $50 billion by 2030 to climate-proof Africa and build resilience in different sectors including agriculture, infrastructure, food systems and urban areas, as well as creating jobs.
This is a boost to the program’s initial target of $25 billion and will be achieved through a convergence of private-sector leadership, innovation and resilient economic growth, according to the GCA.
COP observers invited to reveal who is bank-rolling their participation at climate talks
Bernadette Arakwiye, Rwanda’s environment minister, told the summit that Africa needs to shift from a position of deficit to opportunity, and start leveraging its assets by unlocking domestic capital. “Africa’s financial institutions hold trillions in assets and yet only a fraction is flowing to climate resilience – we need to change this,” she added.
Investing for resilient growth
Unlocking private finance would scale up adaptation investments to equip countries to quickly respond to climate shocks, Arakwiye emphasised, adding that private capital can move the continent away from small and fragmented initiatives to large-scale bankable projects.
The Baku-to-Belém Roadmap for boosting climate finance to $1.3 trillion a year by 2035, to be presented at COP30, will go some way in showing how more funds can be raised for adaptation, including through multilateral development banks, private investment and country platforms for investment, Melanie Robinson, global climate director at the World Resources Institute (WRI), told journalists this week.
Comment: How COP30 could deliver an ambitious outcome on global finance flows
Citing WRI’s research, she noted that every dollar invested in adaptation can generate more than ten times its value in economic, social and environmental benefits.
In addition to finance, policy and regulatory changes such as insurance systems, land zoning and business incentives are also needed to support adaptation on the ground, she said.
“COP30 will be an opportunity to focus more on adaptation and resilience – and this is about investing, not just to save lives, although that’s very important, but actually to drive resilient growth and enable communities and businesses to thrive in a changing climate,” she added.

Can COP30 turn adaptation talks into real-world investments?
The head of the United Nations has launched an initiative aimed at holding artificial intelligence companies accountable for their exploding environmental impacts, including their carbon emissions, the amount of water and land used for data centres, and the energy they consume.
During a speech at London Climate Action Week on Tuesday, António Guterres noted that AI can accelerate climate solutions, among other key challenges, and said its potential must be harnessed.
“But AI is also hungry for land, water and power,” he emphasised, adding that the data centres needed to run AI models already consume more electricity than most countries.
The UN Secretary-General repeated a call he first made in July 2025 for all big AI companies to commit to power every data centre with renewable energy by 2030.
Some tech firms have announced they are sourcing or building out clean energy to run their hubs, but growing power demand is also contributing to gas-fired generation in the US, according to data from Global Energy Monitor.
The International Energy Agency (IEA) estimates that data centres are set to more than double the emissions from the electricity they use between 2024 and 2030 in a high-growth scenario. But AI’s use could lead to far larger reductions in the energy sector through efficiency gains if adopted widely.

At the 11th Our Ocean conference in Kenya, its founder John Kerry says the ocean must become central to climate solutions and needs to be looked after
‘No more hidden costs’
Proposing the new “AI Environmental Transparency Initiative” on Tuesday, Guterres also urged big AI firms companies to measure and publicly disclose the full environmental impact of their systems, including their carbon, water, and land footprints.
“No more hidden costs. No more shifting the burden onto those least able to bear it. It is time to come clean,” he said in a major speech on responding to the world’s twin climate and energy crises. “If AI is to help build a better future, it must be honest about what it costs us now.”
A report issued earlier this month by the UN University Institute for Water, Environment and Health noted that most current assessments of AI’s environmental cost focus on carbon emissions from training models. But, it added, this misses a substantial part of the picture.
Every kilowatt-hour of electricity for AI also carries a water footprint, from cooling and generation, and a land footprint, from infrastructure and supply chains, it said.
Explainer: Will AI data centres make or break the energy transition?
The report estimated that AI data centres globally could consume 945 terawatt-hours of electricity annually by 2030 – more power than all but five countries and roughly twice France’s 2025 consumption.
Offsetting this carbon footprint by 2030 would require growing some 6.7 billion trees over 10 years, it calculated. Producing power for the data centres would consume water equal to the basic needs of 1.3 billion people in sub-Saharan Africa for a year and take up land of more than 14,500 square kilometers, roughly twice the Jakarta metropolitan area.
The European Union said earlier this month it will develop minimum energy-efficiency standards for both new and existing data centres, with a “needs assessment” due by 2027, Reuters reported. It’s also planning a sustainability label for data centres, covering criteria including water use and clean energy supply – but that has been delayed.
US community push-back
Asked after his speech what the response had been, the UN chief said “we’ll see”, without giving more details.
But, he argued that, in his view, the push for transparency “is perfectly reasonable and even positive for the AI industry, because eventually some people will say that they consume much more than they really do”. “I think the truth is essential,” he added.
Concerns about the environmental impacts of AI and the infrastructure needed to run the technology have led to growing opposition in some communities, especially in the US.
This month, Monterey Park in Los Angeles County was the first city in the United States to enact a citywide prohibition on data centres through a voter-approved ballot measure. The developers behind a proposed centre in the area had already pulled the project in April amid an increasingly hostile local environment and regulatory uncertainty.
The vote that stopped a data center: US communities query resource-hungry AI
According to nonprofit Data Center Watch, around $64 billion-worth of data centre projects nationwide were delayed or blocked between May 2024 and March 2025 as communities pushed back against them.
Industry lobby groups argue that data centres can provide economic benefits in their host communities. According to the US-based Data Center Coalition, which represents big operators and developers, data centres generate tax revenue, support construction and technical jobs, and provide infrastructure needed for cloud computing, scientific research and AI development.
The industry has also challenged claims that data centers necessarily raise electricity costs for households.
Force for good?
The UN chief said benefits can be few in the places that are home to the data centre, while “communities are often left in the dark about the environmental impact of the infrastructure rising around them”.
Guterres said companies have an “obligation” to be clear and open about the services they are offering but also the level of resources they require.
“Transparency is essential for the decisions that communities must make – and transparency is essential even for the future of artificial intelligence, and to make sure that artificial intelligence is essentially a force for good,” he told an audience of climate professionals in London
A senior UN official told journalists ahead of Tuesday’s announcement that the AI industry has started to talk about and disclose some of their impacts, but those efforts are not yet comprehensive enough.
The hope is that the new initiative will “encourage the industry to come together and take further action on it”, the official said.

Cited 23 June 2026: Project Cosmos launch | Science ‘under attack’ at Bonn | Emissions inequality
Welcome to Cited, your essential guide to new climate research.
In the news
SCIENCE ‘UNDER ATTACK’: Climate Home News reported that “dozens” of countries called out “coordinated attacks” aimed at “undermining the role of climate science” at UN climate talks in Bonn, Germany, last week. According to the outlet, the countries said that UN decision-making had to remain based on the “best available science”, including the reports of the Intergovernmental Panel on Climate Change. One negotiator said that India and Saudi Arabia “opposed calls in draft texts to encourage scientific work on scenarios that would minimise the magnitude and duration of any overshoot of 1.5C”, the article noted. For more, read Carbon Brief’s summary of the negotiations.
REPORT OPPOSITION: “Oil industry allies” in the US are targeting a report on extreme weather attribution, due to be published by the National Academies of Sciences, Engineering and Medicine, according to Politico. The outlet reported that the “heightened scrutiny – which involves a secretive opposition research group scouring scientists’ emails – has prompted two people to leave the 15-person panel tasked with producing the report”. Separately, the Guardian reported that the Trump administration has “reversed its decision” to dismantle the Ocean Observatories Initiative, a $368m deep-sea observation system.
SUPER EL NIÑO: BBC News reported that the US National Oceanic and Atmospheric Administration announced that El Niño had “officially begun”. Forecasts suggest the event could be among the “strongest ever recorded”, it added. Meanwhile, a “vigorous debate” is taking place about whether climate change is making the El Niño phenomenon more intense, according to the New York Times. The outlet explained that some scientists see the run of “comparatively strong” El Niño events in recent decades as an indication that “climate change is supercharging El Niño”. However, it added that “others say there is no clear evidence to support that theory”.

Spotlight
Introducing: Project Cosmos
Carbon Brief explains how it built a major new database of climate science research and unveils a new ranking of the 500 most highly cited publications, authors and institutions in climate science.
This week, Carbon Brief launched Project Cosmos – the world’s largest and most complete database of climate change research.
The database features more than 1.8m academic papers, books and reports, capturing the vast body of human knowledge about climate change that has accumulated over more than a century of academic study.
The climate science “universe” is based on reports from the Intergovernmental Panel on Climate Change (IPCC), which are recognised as the world’s most authoritative summaries of the latest climate science.
Since its first report was published in 1990, humanity’s knowledge about human-caused climate change has ballooned. The IPCC has published six sets of reports in total – each one longer than the last.
In total, IPCC reports reference more than 100,000 other papers, books and reports. This is the core of our climate science universe. Carbon Brief then built on this core, by looking at four other sources of data. Read more about how the Cosmos database was created here.
Every single publication in the Cosmos database is linked to at least one other through references. Visualising these links reveals a “galaxy” of references. In the image above, each colour and cluster reveals different topics and densities of research. Explore the galaxy in an interactive map here.
Cosmos 500
As part of an initial wave of preliminary analysis to demonstrate the scope of the Project Cosmos database, Carbon Brief has ranked the 500 most highly cited publications, authors and institutions in the database.
The most highly cited climate scientist is Prof Philippe Ciais, who has spent almost four decades researching the planet’s carbon cycle – and the ways in which humans have been impacting its balance. Carbon Brief recently interviewed Ciais in Paris.
The US tops the tables for the most highly-cited authors and institutions. Almost half of the 500 most highly-cited authors are from US institutions. This raises particular concerns for the future of climate science, as American climate scientists and institutions are coming under attack under the Trump administration.
Experts from global south countries account for only 4% of all authors in the Cosmos 500. China stands out as the most highly-cited global south country. Meanwhile, only 10% of authors in the Cosmos 500 are women.
There are many possibilities for future avenues of research using the Cosmos database. Over time, the database could be used to reveal, for example, how interest in different areas of climate science has changed over time, plus identify potential knowledge gaps and, thus, opportunities for future research.
Carbon Brief invites researchers – including academics, journalists and analysts – to submit their own proposals for co-authored studies, literature reviews and analytical projects.
