Last week, hundreds of scientists, policymakers and journalists flocked to the University of Exeter to attend an international conference on “tipping points”.
The conference saw experts discussing the dangers of a range of Earth system tipping points, including the dieback of the Amazon, the melting of the Greenland ice sheet and the shutdown of the Atlantic Meridional Overturning Circulation (AMOC).
Attendees also explored “positive tipping points” – large-scale, self-propelling social changes that would reduce the impact of humans on the climate.
(For more on the key talking points, new research and ideas that emerged from the four-day event, see Carbon Brief’s full write-up of the event.)
On the sidelines of the conference, Carbon Brief asked a wide range of delegates which tipping point concerns them the most.
These are their responses, first as sample quotes, then, below, in full:
- Prof Gabi Hegerl: “I am particularly worried about tipping points that involve the biosphere and humans due to breaching thresholds for heat or drought that then ripple into food availability, livelihood and ecosystems.”
- Prof Carlos Nobre: “The Amazon is a very serious tipping point, because [dieback] could release around 250bn tonnes of CO2 by 2100 – which will make it impossible to [limit global warming] at 1.5C.”
- Gaia Vince: “I would say that we have already passed the tipping point for coral reef ecosystems…As a scuba diver, I find it a tragedy because I love coral reef ecosystems, but it’s also a tragedy for human systems.”
- Dr Andrew Hartley: “The tipping point I’m most concerned about is Amazon forest dieback…because of the significance of the carbon cycle and the feedback to the global climate. Also [due to] the effects that Amazon tipping has on food security, both locally and globally.”
- Prof Tim Lenton: “The Atlantic Meridional Overturning Circulation, or AMOC, for sure. The consequences of crashing that would be devastating globally – and also for where I live in the UK.”
- Prof Peter Cox: “The one that I’ve worked on most and worries me most at the moment is Amazon dieback. And that’s because we’ve got two things, two stressors, going on at once that push it in the wrong direction. Climate change is one, deforestation is another.”
- Prof Johan Rockström: “The tipping element that worries me most is coral reef systems, for the simple reason that the scientific uncertainty range is very limited.”
- Dr Patricia Pinho: “For me, it is the Amazon…I think it’s going to be a really profound, irreversible change that will affect the global population in the most dramatic way.”
- Prof Ricarda Winkelmann: “I’m mostly concerned about the Greenland and West Antarctic ice sheets. This is because we know that, even at lower warming levels, they are already at risk of transgressing tipping points in certain regions.”
- Dr Nico Wunderling: “The tipping element that worries me most is the Amazon rainforest. This is because the Amazon rainforest is not only threatened by climate change, but also by deforestation at the same time.”
- Dr Rebecca Shaw: “The coral reef tipping point…It signals the end of the most colourful and biodiverse ecosystem which supports the nutrition and livelihoods of over one billion people.”
- Dr David Obura: “The ice [tipping elements] – because they are the first ones to go that have cascading impacts on other tipping elements.”
- Dr David Armstrong McKay: “The Amazon is actually probably closer to a deforestation-induced tipping point than to a climate change-induced tipping point. So, I actually think that could be potentially in the offing sooner than we would like.”
- Kate Raworth: “The tipping point that I fear we will fail to cross is [the social tipping point] around transforming our mindsets.”

I am worried about all of them, but for the immediate future, I am particularly worried about tipping points that involve the biosphere and humans due to breaching thresholds for heat or drought that then ripple into food availability, livelihood and ecosystems. The Earth system tipping points will do that too, but maybe a little bit later. Examples [of this] are the coral diebacks triggered by marine heatwaves, forest change and fires, and droughts threatening livelihoods and putting people on the move.
I did a research project on the US Dust Bowl and the trigger [for that event] was drought causing vegetation and crop dieback, [which led to] extreme heat and dust storms in response – and migration, as memorialised in [the 1939 John Steinbeck novel] The Grapes of Wrath. And, now with warming, all droughts get supercharged.
Prof Carlos Nobre
Scientist and meteorologist who spearheaded the multi-disciplinary, multinational large-scale biosphere-atmosphere experiment in Amazonia
The Amazon is a very serious tipping point, because [dieback] could release around 250bn tonnes of CO2 by 2100 – which will make it impossible to [limit global warming] at 1.5C. We could also lose the largest [host to] biodiversity on the planet, which would induce a tremendous, large number of epidemics and several pandemics. Also, of course, the Amazon forest controls aspects of the global climate. In South America, the climate is entirely controlled by the Amazon forest.
I’m most worried about Amazon [dieback] because I have worked on it for 40 years. But the other tipping points deeply concern me. The melting of the permafrost will release more than 200bn tonnes [of greenhouse gases], mostly methane. Ice sheet melt in Greenland is a very serious tipping point because it could raise sea level rise by three metres in 200 years. The melting of Greenland has already started. Species extinction is also very serious.
One thing that was not much talked about [at this conference] is that when the ocean heats up, particularly the Arctic Ocean, then a tremendous amount of methane is released. And if that happens – if the Arctic Ocean warms up by 3-4C – the amount of methane that would be released could see [air] temperatures reach 8-10C [above pre-industrial levels]. At 8-10C, the only inhabitable places for us humans will be the top of the Alps, the Andes and the north and south poles. The rest of the planet would be uninhabitable.
Gaia Vince
Science writer and broadcaster
I would say that we have already passed the tipping point for coral reef ecosystems, for example. That really is a tragedy. As a scuba diver, I find it a tragedy because I love coral reef ecosystems, but it’s also a tragedy for human systems. They are the nursery for our fisheries. And, of course, they’re not just fisheries – they are a valid ecosystem and a biodiversity hotspot. This will have untold consequences and cascading impacts for other parts of the ecosystem, for example, the cycling of nutrients and coral reefs are really important to stop coastal erosion. And they actually provide sand, the lovely white sand that people go on holiday for Bucha.
Dr Andrew Hartley
Climate impacts scientist at the Met Office Hadley Centre
The tipping point I’m most concerned about is Amazon forest dieback and reduction in the function of the Amazon forest, because of the significance of the carbon cycle and the feedback to the global climate. Also [due to] the effects that Amazon tipping has on food security, both locally and globally, because of [the Amazon’s] contribution to major commodity markets, such as soybean and maize.
This might interact with climate change in the future to lead to more severe events, particularly in populated areas of Brazil. If an Amazon tipping point were to occur, it might lead to more severe events on the coast of Brazil which would affect a much larger population. There are negative impacts across the forest from the drying of the forest, for example for the Indigenous communities, but also globally.
Prof Tim Lenton
Founding director of the Global Systems Institute and chair in climate change and Earth system science at the University of Exeter
The Atlantic Meridional Overtoning Circulation, or AMOC, for sure. The consequences of crashing that would be devastating globally – and also for where I live in the UK. By our own calculation, we could have less than half the viable area for growing a couple of major staple crops, wheat and maize worldwide. We would have a widespread water crisis. We could have collapses of the monsoons in West Africa and India that would displace hundreds of millions of people. It is hard to see that as anything other than a catastrophe.
Prof Peter Cox
Professor of climate system dynamics in mathematics and director of the Global Systems Institute at the University of Exeter
The one that I have worked on most and worries me most at the moment is Amazon dieback. And that’s because we’ve got two things, two stressors going on at once that push it in the wrong direction. Climate change is one, deforestation is another. You can imagine crossing the boundary in various ways – but, if you push diagonally, you get there quicker.
If I had spoken to you 25 years ago, I would have said I’m really worried about [Amazon dieback]. Then I went through a phase of thinking that the models have overdone it. And now I’m thinking the models that don’t include land-use change are underdoing it. So, I’m more concerned about that one.
There are others as well, but that is the one that is also quite fast. The other [tipping points] we worry about, we’re worried about a long-term commitment. It takes a while for the AMOC to shut down, it really does. It takes a while for the Greenland ice sheet to melt. We’ve done work that suggests you can overshoot even a little bit for these slow systems. The Amazon forest is a decadal dieback, especially if it is fire driven.
Prof Johan Rockström
Director of the Potsdam Institute for Climate Impact Research (PIK) and professor in Earth system science at the University of Potsdam
There is not a simple answer to this – there is a two-part answer.
The tipping element that worries me most is coral reef systems, for the simple reason that the scientific uncertainty range is very limited. We have, unfortunately, ample evidence that at 1.5C we’re very likely to knock over, potentially, the entire tropical coral reef system on Earth. [This threatens] the livelihoods of 400 million people and a fundamental nursing ground for the whole ocean food web. So that is one deep concern. It is the canary in the coal mine – the first kid on the block to fall over. We’re so close.
The second one is AMOC – the whole overturning of heat in the Atlantic, which connects the entire ocean system. Not only is the latest science showing that we are going from low likelihood to uncomfortably high likelihood, but we also know – with very little uncertainty – that this would cause a catastrophic impact across the entire world, and it would go fast. So the AMOC, I would argue, is today the most important scientific message to the world. If you want a really hard-hitting reason to act at a level of planetary emergency, it is the AMOC. That is the second one.
From a planetary boundary perspective, it is important to recognise that – on climate science grounds – the Amazon basin is not at risk of tipping until 3-5C of warming. But as soon as you factor in loss of biodiversity, deforestation and changes in hydrology – then the temperature risk goes down to between 1.5-2C. So suddenly – when taking a more integrated [assessment] approach – the conclusion is that it is also very close to a tipping point.
Dr Patricia Pinho
Deputy science director at the Amazon Environmental Research Institute (IPAM)
For me, it is the Amazon. When we think of the planetary crisis, we think about the Amazon and all the regulating climate services it provides. This is not only regionally, but we know it’s a global “climate good”, if you will. But it is highly sensitive to land-use change and increasing temperature. So, if we transition to a point of no return – Amazon dieback – and transforming or transitioning to another ecosystem, the function of the forest will not be doing what it has been doing for the past millennium and so on. And then we cannot revert this loss. I think it is going to be a really profound, irreversible change that will affect the global population in the most dramatic way.
Of course, we have the people on the front line that I’m working with – Indigenous people, traditional population – that are safeguarding this resource, but they are also at the front line of climate risks and the impacts that we already observe. If we miss this opportunity of really reverting from increasing greenhouse emissions and increasing temperature, we’re going to miss the window of opportunity to really protect the region, protect the ecosystem and the forest for the global society.
Prof Ricarda Winkelmann
Founding director of the Max Planck Institute of Geoanthropology and professor of climate system analysis at PIK and the University of Potsdam
So I am thinking about this from a risk perspective – so both the likelihood as well as the impacts – and I think the answer depends on that. Because when it comes to the likelihood and the particular threshold – and we know about those – I’m mostly concerned about the Greenland and the West Antarctic ice sheets. This is because we know that, even at lower warming levels, they’re already at risk of transgressing tipping points in certain regions.
But when it comes to the impacts and also the timescales over which those play out, there are other tipping elements that worry me most. In particular, regional tipping elements. So if we think of the mountain glaciers, for instance, these impacts are already experienced right now and several mountain glaciers are undergoing these accelerated changes. And so thinking about the timescales when it comes to the impacts is also incredibly important.
Dr Nico Wunderling
Junior professor at the Center for Critical Computational Studies at Goethe University Frankfurt and researcher at the Potsdam Institute for Climate Impact Research.
The tipping element that worries me most is the Amazon rainforest. This is because the Amazon rainforest is not only threatened by climate change, but also by deforestation at the same time. So that means that the critical threshold from climate change alone, at around 3-4C of global warming, can come down to 1.5-2C. Climate change and deforestation basically go hand-in-hand to lower the [Amazon’s tipping] threshold because of this double threat.
Dr Rebecca Shaw
Chief scientist and senior vice-president at WWF
The coral reef tipping point – it comes first because of warming surface waters, and then the outcome is sealed by ocean acidification. It signals the end of the most colourful and biodiverse ecosystem which supports the nutrition and livelihoods of over one billion people and has captured the imagination of more people than any other through the characters like Nemo the clownfish, SpongeBob SquarePants, and, of course, Frank the coral [a character from an educational YouTube video].
If humanity is not motivated to act in the face of the loss of coral reefs, is there hope that we will act in time to prevent the Amazon and glacier tipping points?
Dr David Obura
Chair of the Intergovernmental Science-Policy Platform on Biodiversity and Ecosystem Services and founding director of CORDIO East Africa
The ice [tipping elements] – because they are the first ones to go that have cascading impacts on other tipping elements. When [ice masses] reduce, we lose their albedo, waters heat up more [and] the AMOC can collapse. That has the biggest impact across the planetary system, including the Amazon.
My own [research], of course, is coral reefs. So, in a way, the coral reef tipping point does concern me the most. [But] it doesn’t have cascading impacts on other tipping elements. It does on people, in socioeconomic terms – but not on other system elements. So, in a sense, it is the least worrying one.
Dr David Armstrong McKay
Lecturer in geography, climate change and society in the school of global studies at the University of Sussex and lead author on an influential tipping points assessment, published in Science in 2022
One of the tipping systems that concerns me the most is Amazon rainforest dieback. Because even though we assessed it a few years ago as having a warming threshold that’s a bit higher than what we might be seeing – we’ve thought it is maybe at a best estimate of 3.5C – there’s also deforestation as well. The Amazon is actually probably closer to a deforestation-induced tipping point than to a climate change-induced tipping point. So I actually think that could be potentially in the offing sooner than we would like. That would have huge impacts for biodiversity, for South America as a whole, by shifting rainfall patterns, which would really affect a lot of people for agriculture or ecosystems. Also, the Amazon as an ecosystem is so incredibly biodiverse and amazing in itself, it would be a tragedy to lose it.
Kate Raworth
Senior visiting research associate and lecturer at the University of Oxford’s Environmental Change Institute and co-founder and conceptual lead of Doughnut Economics Action Lab
The tipping point that I fear we will fail to cross is [the social tipping point] around transforming our mindsets. We need to move from the extractive, degenerative economy towards a regenerative one. This all starts within our head and it underlies everything.
[A failure to do this] is what is driving us towards all these [Earth system tipping points].

DeBriefed 3 July 2026: US faces scorching Independence Day | Record ocean temperatures | Vietnam’s EV surge
Welcome to Carbon Brief’s DeBriefed.
An essential guide to the week’s key developments relating to climate change.
This week
Heating up
NOT FREE FROM HEAT: “Dangerous, record-breaking” heat altered plans for 4 July celebrations across the US this weekend, reported the Associated Press. New York and Boston hit 100F (37.8C) on Thursday, said the newswire. CNBC reported that temperatures of up to 105F (40.5C) are forecast in central and eastern parts of the country, with “daily, monthly and all-time records possible”.
TEMPERATURES SOAR: Heat that hit western Europe last week spread east to “scorch” Germany, Hungary, Romania, Poland and others, said Bloomberg. Red warnings for extreme heat were issued in a number of nations, noted the outlet, adding that the heat “underscores how climate change is transforming summers in the world’s fastest-warming continent”. The Independent said last month was confirmed to be England’s hottest June on record.
HEAT DEATHS: June’s extreme temperatures caused more than 2,000 excess deaths in Spain and France, reported the Guardian. The countries are bracing for further heat that “could bring temperatures of 44C (111F) over the coming days”, said the newspaper. Deaths in France rose almost 30% at the heatwave “peak” on the week of 22 June, according to Le Monde. Last week’s conditions also led to around 480 excess deaths in the Netherlands, reported Reuters.
BOILING: Global ocean temperatures reached record levels for this time of year, reported NBC News, “fuelling fears of more dangerous heatwaves this summer and fanning concerns over the escalating global climate crisis”. Scientists told the Financial Times that this could lead the world towards “uncharted territory”. The newspaper said global average sea surface temperatures reached 20.96C on 21 June, exceeding June records for 2023 and 2024.
Around the world
- GOAL DROPPED: The World Bank will “abandon” its goal to devote 45% of annual lending resources to climate-related projects, reported Reuters. Carbon Brief explored what it could mean for global climate action.
- FIVE-YEAR PLAN: China plans to invest more than 20tn yuan ($2.9tn) in “key energy projects and new business models” over the next five years, according to International Energy Net.
- DRILLING: The Guardian said UK Labour politicians “urged” the likely next prime minister Andy Burnham to ignore “deluded” calls to develop the Rosebank oil field located in the Atlantic north of Scotland.
- PLASTIC TALKS: Countries and activists feared key issues could be sidelined at “critical” talks on a global treaty to curb plastic pollution in Kenya, said Climate Home News. A treaty could have “important implications” for climate change, reported Carbon Brief in 2024.
- CANADA PIPELINE: Canadian prime minister Mark Carney announced plans to build an oil pipeline to supply Asia with up to 1m barrels per day, reported the Financial Times. Earlier this week, Carney called the previous government’s climate plans “expensive” and “divisive”, said CBC News.
63
The number of UK newspaper editorials calling for more oil and gas extraction in the North Sea so far in 2026, according to Carbon Brief analysis.

Captured
Wind and solar were the world’s largest source of new energy in 2025, according to Carbon Brief analysis of the latest Energy Institute statistical review of world energy. Wind and solar also saw the fastest growth, up by 18% in 2025. Nevertheless, every source of energy – including coal, oil, gas, nuclear and hydro – also reached global all-time highs last year.
Spotlight
Vietnam’s EV surge
Carbon Brief explores the reasons behind soaring electric-vehicle sales in Vietnam.
Motorbikes are a constant fixture on streets across Vietnam. They pollute the air in cities and make crossing the road a feat of endurance.
But, increasingly, people are moving away from petrol-powered vehicles to save money and reduce air pollution.
Sales of electric motorbikes, scooters and mopeds more than doubled in Vietnam last year, according to a recent report from the International Energy Agency (IEA).
This identified that Vietnam has the largest electric vehicle (EV) market in south-east Asia.
Nearly one-in-five of the two-wheeled vehicles sold last year were electric, it noted, in a nation with 102 million people and 77m motorbikes.
This is “particularly impactful” given they are the main mode of transport in Vietnam, said Lam Pham, Asia energy analyst at thinktank Ember. He told Carbon Brief:
“Electrifying road transport is essential for Vietnam to achieve its net-zero target by 2050. Road transport accounted for around 86% of transport-sector emissions in 2022.”
The nation has just 6.8m cars, but this number is also climbing, partly due to EVs, with nearly 40% of new car sales being electric.
This is “above levels seen in most European countries”, noted the IEA. (The UK’s figure is around 30%.)
EV incentives
Fuel costs surged in south-east Asian countries earlier this year after the energy crisis caused by the US-Israel war on Iran.
This “accelerated” discussions from “why use EVs” to “why keep paying more for fuel”, said Dr Tham Nguyen, a lecturer at the Ho Chi Minh City campus of Australia’s Royal Melbourne Institute of Technology (RMIT) University, who has researched Vietnamese public attitudes to EVs.
But the surge is “not driven by fuel prices alone”, noted Pham.
Increased EV sales can also be attributed to a “convergence of affordability, convenience and sustainability”, Nguyen said:
“Vietnamese consumers buy EVs because they see real value with immediate personal benefits, such as cost savings and energy security, alongside long-term environmental gains.”
Government policies have also incentivised sales through registration fee exemptions and tax cuts for EVs.
Another factor is affordable EVs sold by Chinese companies and Vinfast, a Vietnamese manufacturer. The IEA report noted that Vietnam is the only country in south-east Asia with “sizeable” domestic production of accessible EVs.
Vinfast reported a 219% year-on-year increase in orders for electric motorbikes and e-bikes in the first quarter of 2026, but the company has yet to turn a profit.
Pham noted that “growing public awareness of air pollution” has also “dramatically strengthened” public support for EVs.
Future plans
Vietnam’s major cities also have plans to get drivers to go electric or turn to public transport.
The capital city Hanoi announced that it would ban fossil-fuel-powered motorbikes from a central zone this month, but this has been postponed until 2028.
Ho Chi Minh City, the nation’s largest city with more than 9.5 million people, intends to introduce low-emission zones and swap 400,000 petrol-powered motorbikes to electric by 2028.
The city’s green transport plans focus on metro lines, electric buses and e-bikes, explained RMIT associate professor Catherine Earl. She noted that walking and cycling are currently “not popular, accessible or safe for many residents in Ho Chi Minh City’s hot and humid climate”.
Looking ahead, Pham said Vietnam could focus on “purchase subsidies, financing schemes and adequate charging or battery-swapping infrastructure, to ensure lower-income riders, including delivery and ride-hailing drivers, are not negatively affected”.

The post DeBriefed 3 July 2026: US faces scorching Independence Day | Record ocean temperatures | Vietnam’s EV surge appeared first on Carbon Brief.
The World Bank has abandoned a target for 45% of the funding it gives developing countries to be “climate finance”, following months of pressure from the Trump administration in the US.
However, a concerted effort by developed- and developing-country shareholders has seen the bank hold onto its “action plan” for tackling climate change.
The multilateral development bank (MDB) – which is headquartered in Washington DC – is the single largest provider of climate finance globally, distributing $39.2bn in 2025 alone, primarily as loans.
Amid widespread aid cuts by developed countries, the World Bank and other MDBs have previously pledged to significantly scale up their climate finance over the next decade.
Despite scrapping its central target, the bank says it will continue to support the demands of its “clients”, many of which have explicitly stated their need for climate-related investment.
Here, Carbon Brief looks at the likely impact of the World Bank’s policy shift and whether it is – as one expert puts it – “mostly a symbolic victory” for the US.
- How does the World Bank support climate action?
- Why has the World Bank abandoned its climate-finance target?
- Why is the World Bank important for international climate finance?
- How will these changes affect global climate action?
How does the World Bank support climate action?
The World Bank is the oldest and largest MDB. It is tasked by its 189 member governments – the bank’s shareholders – with supporting development projects around the world.
The US is the bank’s largest shareholder, followed, in order, by Japan, China, Germany, France and the UK.
Every year, the bank provides billions of dollars – predominantly as loans – to developing countries.
(One part of the World Bank, the International Development Association – IDA – specifically distributes grants to lower-income nations, as well as lower-interest loans.)
Through its financing, the World Bank also has an important role in “mobilising” private investments in developing countries.
In recent years, the bank has increasingly focused on helping developing countries to cut emissions and adapt their economies for climate change.
The World Bank provided $164bn in what it calls financing with climate “co-benefits” between 2020 and 2025.
The largest share of this funding – roughly one-fifth – went to clean energy and electricity access projects. Smaller shares went to areas such as public transport, water supply and sustainable farming.
As the map below shows, the largest recipients of the bank’s climate funds since 2020 have been emerging economies, such as Turkey ($10.3bn), India ($9bn) and Nigeria ($6.3bn).
Among the largest World Bank projects in recent years are two extensive programmes in India, totalling nearly $3bn, supporting renewables and green hydrogen.
Others include $1.7bn for a Pakistan hydropower project, $926m for Iraq’s railways and $803m to boost “green development” in Colombia.
Despite the bank’s major role in providing climate finance to developing countries, it has faced heavy scrutiny from climate advocates.
In particular, they have noted the dominance of loans that push developing countries further into debt. The World Bank has also been criticised for a lack of transparency around how it classifies projects as “climate-related”, as well as “over-reporting” of climate finance.
Why has the World Bank abandoned its climate-finance target?
When World Bank president Ajay Banga – nominated by former US president Joe Biden – took over the institution in 2023, there were widespread calls for MDB reform.
Many of the bank’s shareholders wanted to see billions more dollars being channelled to support climate action. Later that year, Banga announced that the bank would ensure that 45% of the bank’s funding was climate finance by 2025.
This replaced an existing target of 35% for climate finance between 2021 and 2025, which had been set out in the bank’s second climate change action plan (CCAP).
The CCAP is intended to “mainstream” climate action in the bank’s work. With it in place, the World Bank’s climate finance more than doubled from $17.2bn in 2020 to $39.2bn in 2025.
As the chart below shows, this meant the World Bank exceeded its 2025 goal, with climate-related projects making up a 48% share of total funding that year.
When Biden was replaced by Donald Trump as president in 2025, the US administration turned against international cooperation, including climate finance.
However, the US did not walk away from the World Bank, where it exerts considerable power as the largest shareholder.
With the CCAP due to expire in July 2026, the US has spent months pressuring the bank and its shareholders to weaken or abandon the plan altogether.
US Treasury secretary Scott Bessent issued a statement during the 2026 World Bank and International Monetary Fund (IMF) spring meetings in April 2026, in which he called for “jettisoning” the 45% climate-finance target. More broadly, he said:
“We welcome the coming expiration of the CCAP and…expect the bank to immediately shift its myopic focus on climate and financing volumes to one that emphasises high-quality, durable projects.”
This vision involves a push for the World Bank to finance more fossil-fuel projects, including drilling for new gas. (The bank has committed since 2019 to stop funding upstream oil and gas projects.)
The decision on whether to continue with the CCAP was negotiated behind closed doors by the board of directors – representing national shareholders. There were reports of “deep divides”.
A joint statement from 19 of the 25 directors last year affirmed the need for both a plan and a target. The US, Russia, Kuwait and Saudi Arabia all declined to sign up, while Japan and India abstained, according to Reuters.
There were reports of European nations championing a climate plan, bolstered by support from the developing countries that would stand to receive climate finance. The US call to drop the 45% target entirely was reportedly backed by Saudi Arabia and Russia.
Ultimately, the day before the CCAP was due to lapse, the World Bank announced what appeared to be a middle ground. It would drop both the 45% target and the 35% goal it had replaced, while also “extend[ing]” the CCAP.
UK development minister Jenny Chapman told a committee hearing in the House of Commons the next day that this marked a “compromise”. She said:
“It wasn’t clear we were going to get a CCAP at all and a bank without an action plan on climate is a problem for us – so that’s a good outcome.”
Supportive shareholders had been pushing for a one-year extension of the plan. While the World Bank did not initially define the length, Chapman confirmed on LinkedIn that the plan had, in fact, been extended “indefinitely”.
The bank said it would also engage an “independent evaluation group” to assess the CCAP, in line with a board request.
Gaia Larsen, director of climate finance at the World Resources Institute (WRI), tells Carbon Brief that this evaluation will likely be “relatively free from political ideology” and could be “focused on how to make the CCAP more effective”.
Why is the World Bank important for international climate finance?
Under the Paris Agreement, developed countries – including major World Bank shareholders in Europe and elsewhere – are obliged to provide climate finance for developing countries.
This includes a target of $300bn a year by 2035, which is expected to largely come from developed countries. One significant way these nations can contribute to this goal is via their support for MDBs, particularly the World Bank.
The World Bank has described itself as “by far the largest provider of climate finance to developing countries”. Each year, it oversees half of all climate finance from MDBs and far more than any single donor country.
Many developed countries have, therefore, enthusiastically backed the World Bank’s climate efforts, as well as a “bigger” role for MDBs in development more broadly. The bank can lend sums that far exceed the amount of new public finance that individual nations are willing to commit.
This is particularly significant, given many of these nations, including the UK, Germany and France, have announced large cuts to their aid budgets in recent years.
Carbon Brief analysis suggests that roughly a fifth of the international climate finance provided and “mobilised” by developed countries in recent years can be attributed to their World Bank contributions, as the chart below shows.
(This only accounts for the World Bank financing that can be linked to developed-country shares in the bank. Developing countries, such as China, also have significant shares, which are not included in the chart below.)
MDBs – including the World Bank – have committed to providing $120bn in climate finance to developing countries by 2030.
This was set to come from greater shareholder contributions, combined with a programme of reforms to free up capital.
If the World Bank continued to provide half of the MDB total, it would need to increase its climate finance by around 50%, from $39.2bn today to $60bn in 2030.
Therefore, experts see a “key” role for the World Bank in achieving not only the $300bn target, but also the more aspirational $1.3n target that countries agreed as part of the “new collective quantified goal” (NCQG) on climate finance at COP29 in 2024. This includes the private capital it could “unlock” through its lending.
Joe Thwaites, international climate finance director at Natural Resources Defense Council (NRDC), tells Carbon Brief that these “NCQG politics” are “quite important”. He says:
“The maths of the $300bn does not work if the MDBs pull back and so I think that’s why you’re seeing developed countries taking a stand.”
How will these changes affect global climate action?
To date, the World Bank has only released minimal details about its new climate plans. As such, experts say the impact on future climate finance remains uncertain.
Jon Sward, environment project manager at the Bretton Woods Project, tells Carbon Brief:
“They have said they are going to retain all the same processes about climate-finance reporting. So, of course, there is a world in which, actually, climate finance continues to increase like it has been.”
Some of the World Bank’s internal organisations will, in fact, keep their climate-finance goals for the time being. For example, the IDA’s largely grant-based funding retains a 45% target for its current round, which will last until 2028 – the year of the next US presidential election.
However, WRI’s Larsen tells Carbon Brief that the changes, from a bank that was previously a “champion for climate action”, remain significant:
“This reality, reinforced by the elimination of the 45% goal, means that it would not be surprising to see a reduction in climate investments.”
In a statement, the World Bank said its “work on climate is and will remain firmly client driven”, noting that it supports nations undertaking their Paris Agreement climate plans.
Therefore, its climate focus may come down to whether there is demand for climate action from “client” countries receiving finance.
At an April event in discussion with the climate sceptic Bjørn Lomborg, Bessent said that global financial institutions should focus on growth, characterising climate action as an “elite belief”.
The implication from the US Treasury secretary was that recipient countries are not interested in climate action. However, as reported by Devex, a group of World Bank shareholders representing nearly 100 developing countries, wrote a letter that appeared to push back against this framing.
This “G11+” group, led by Brazil and China, said the bank “must remain firmly client-driven”, noting that countries are “following nationally determined pathways toward climate action”. NRDC’s Thwaites tells Carbon Brief:
“It’s one thing for the Europeans to talk about climate…This was the client countries [100 developing countries] saying: ‘No, we want this.’”
Recent research by the ODI thinktank found that 79% of developing-country officials polled wanted to see MDB investment in solar projects, 54% wanted hydropower and 47% wanted wind power. Only 13% wanted investment in gas-power plants.
Rishikesh Ram Bhandary, a senior development researcher at Boston University, has stressed the need for an “enhanced CCAP”, which could be supported by the bank’s new independent evaluation. Among other things, he tells Carbon Brief:
“The bank needs to make a more convincing case about how climate change is being integrated into development priorities rather than competing with them.”
Thwaites says he is hopeful that the outcome is “mostly a symbolic victory for the US”.
However, he says major shareholders from Europe and elsewhere should make it clear to the bank that it is not “the only game in town” when it comes to climate finance. He says:
“If [the World Bank] are going to cave into one shareholder, when the vast majority of the other shareholders are supportive of continuing climate action, they can take their money elsewhere.”

Q&A: How will the World Bank’s abandoned finance goal affect climate action?
Rich Wilson is CEO of the Iswe Foundation and co-founder of the Global Citizens’ Assembly.
The numbers are stark. According to the 2026 Global Report on Food Crises, 266 million people across 47 countries experienced high levels of acute food insecurity last year, nearly double the figure recorded a decade ago.
Meanwhile, disruptions to oil, gas and fertiliser flows through the Strait of Hormuz drove a 46% month-on-month spike in urea prices early this year, sending agricultural price indices up 8% and raising the spectre of a global affordability crisis.
This is not a blip. It is a new baseline. The EAT-Lancet Commission concluded that food systems now account for roughly 30% of total greenhouse gas emissions and are the largest single contributor to the climate crisis. The science has been clear for years.
Now some of the solutions to the problem are becoming socially acceptable too.

Can giant batteries unlock Africa’s green industrial future?
Battery energy storage systems (BESS) could drive clean tech manufacturing in Africa but shortfalls in finance and data are still limiting deployment at scale
Earlier this year, people from more than 60 countries and territories, selected not by vested interest, but by lottery, spent seven weeks examining the evidence on food and climate for the latest Global Citizens’ Assembly. They heard from scientists, farmers and industry. They worked through 42 hours of structured deliberation, engaging with some difficult trade-offs.
They were not asked to endorse a predetermined conclusion. They were asked an open question: what changes, if any, should we make to how we grow, share and eat food, so that everyone has enough to nourish themselves while tackling the causes and impacts of climate change?
Phase down industrial animal farming
Their answer was unambiguous. They voted to protect forests. They voted to phase down industrial animal food production. They voted for supply chain reform and corporate accountability, explicitly rejecting the idea that the burden of change should fall on individual consumers. All 22 of their Calls to Action passed with over 85% support, a super-majority of randomly selected people from every region of the world, in agreement.
Consider what the assembly was actually being asked to decide. Industrial animal food production is the primary driver of tropical deforestation. Protecting more land as forest and ecosystem means less land available for the expansion of industrial production. That is a real trade-off, with real consequences for real livelihoods. Politicians have spent years avoiding it.
These randomly selected people looked at the evidence, deliberated across time zones and cultures, and chose the forests, with 64% in strong support and a further 20% in favour. People from livestock farming communities voted for change. Not because they were told to. Because deliberation led them there.
We estimate there have now been more than 7,000 citizen participation initiatives worldwide in the last decade. They have been organised because, as our 2025 report: People in the Lead demonstrated, people are now consistently and significantly ahead of politicians on issues ranging from climate to AI governance.
The people know best
What the research consistently shows is that ordinary people, given proper evidence and time, produce recommendations that are more effective and more aligned with public values than what emerges from elected legislatures. The gap in global governance is no longer primarily between science and the public. It is between citizens and their political leaders.
That gap matters for more than procedural reasons. When policy treats people as passive recipients rather than active participants, it leaves out the very actors whose behaviour, trust and consent the transition depends on. Institutions that speak only to other institutions, and negotiate only with state actors and industry lobbies, are missing out on the trust and energy of the people they are supposed to serve.
Governments, left to their own devices, are not moving fast enough to prove that argument wrong. At COP30 in Belém last November, countries failed to agree on a fossil fuel phaseout roadmap, and even full implementation of every submitted national climate plan still leaves the world on course for 2.3 to 2.8C of warming.
Citizens’ track at COP
But the Brazilian presidency grasped something important. Among the conference’s more significant outcomes was the formal launch of a Citizens’ Track within the UNFCCC process, a mechanism for connecting the global participation field to intergovernmental climate negotiations. Türkiye and Australia, who together hold the COP31 presidency in Antalya this November, now have the opportunity to strengthen and institutionalise what Brazil began.
In Guatemala, Indigenous women build climate resilience with old and new farming methods
The question before us is no longer whether citizens can contribute to solving these problems. Across the world, in local food networks, in community assemblies and in participatory planning processes, they already are, quietly generating more ambitious and more legitimate solutions than those emerging from formal diplomatic channels.
What is required now is the political courage to connect people to power. Not to consult citizens and file the results. Not to invite them to observe while the real decisions are made elsewhere. But to recognise the public as partners in perhaps the most consequential governance challenge of our time.
