Every increment of global warming above 1.5C increases the risk of crossing key tipping points in the Earth system – even if the overshoot is only temporary, says new research.
It is well established that if global temperatures exceed 1.5C above pre-industrial levels, there is a higher risk that tipping points will be crossed.
The new study, published in Nature Communications, investigates the risk of crossing four interconnected tipping points under different “policy-relevant” future emissions scenarios.
The authors investigate the risk of tipping where warming temporarily overshoots 1.5C, but global temperatures are then brought back down using negative emissions technologies. They find that the longer the 1.5C threshold is breached, and the higher the peak temperature, the greater the risk of crossing tipping points.
The most pessimistic scenario in the study sees global warming hit 3.3C by the end of the century – in line with the climate policies of 2020 – before dropping back below 1.5C over 2100-2300. Under this pathway, there is a 45% chance of crossing tipping points by 2300, the authors say.
The authors also warn that if global temperatures rise above 2C, the additional risk of tipping for every extra increment of warming “strongly accelerates”.
For temperatures between 1.5C and 2C, the risk increases by 1-1.5% for every 0.1C increase in overshoot temperature. However, for temperatures above 2.5C, tipping risk increases to 3% per 0.1C of overshoot.
The research “underlines the need for urgent emission cuts now that do not assume substantial carbon dioxide removal later”, a scientist not involved in the study tells Carbon Brief.
Overshoot scenarios
Scientists have warned for decades that as the planet warms, there is an increasing risk that Earth systems will cross “tipping points” – critical thresholds that, if exceeded, could push a system into an entirely new state.
For example, if climate change and human-driven deforestation push the Amazon rainforest past a critical threshold, large parts of the forest could experience “dieback”. This would cause entire sections of lush rainforest to eventually shift to dry savannah.
(See Carbon Brief’s explainer on the nine tipping points that could be crossed as a result of climate change.)
The planet has already warmed by 1.3C above pre-industrial levels, and a recent study warned that five tipping elements – including the collapse of the west Antarctic ice sheet – are already within reach.
That study emphasised the importance of limiting global temperature rise to 1.5C above pre-industrial levels – in line with the 2015 Paris Agreement. It finds that warming of 1.5C would render four climate tipping elements “likely” and a further six “possible”. Meanwhile, 13 tipping elements will be either “likely” or “possible” if the planet warms by 2.6C, as expected under current climate policies.
Many of the potential pathways to limiting global temperature rise to 1.5C by 2100 see the planet initially “overshoot” the threshold before negative emissions methods are used to bring temperatures back down.
The new paper investigates 10 future warming scenarios which run to the year 2300. The authors use the PROVIDE v1.2 emission pathways, which they describe as “an extended version of the illustrative pathways identified” used in the recent sixth assessment of the Intergovernmental Panel on Climate Change (IPCC).
The original scenarios run over 2015-2300, but the authors carried them forward for another 50,000 years by following the temperature trajectory set over 2290-2300. All scenarios stabilise at 1.5C, 1C or pre-industrial temperatures. However, many include overshoots, with peak temperatures ranging from 1.57C to 3.30C.
These scenarios show a range of options for how global temperatures change under these 10 scenarios in the “medium term” – until the year 2300 – as well as in the “long term”, which runs 50,000 years into the future to see how the planet eventually stabilises.
Scenarios that reach net-zero or negative emissions by 2100 and maintain them thereafter are classified as “NZGHG emission scenarios”. The table below gives more detail on each scenario.
| Scenario | Overshoot peak temperature | NZGHG | Stabilisation temperature | Scenario assumptions |
|---|---|---|---|---|
| CurPol-OS-1.5C | 3.30C | Never-NZGHG | 1.5C | Follows current (2020) policies until 2100, then declines |
| ModAct-OS-1.5C | 2.69C | Never-NZGHG | 1.5C | Follows current (2020) pledges (NDCs) until 2100, then declines |
| ModAct-OS-1C | 2.69C | Never-NZGHG | 1.0C | Follows current (2020) pledges (NDCs) until 2100, then declines |
| Ref-1p5 | – | not defined | 1.5C | Reference scenario designed in temperature space |
| SSP5-3.4-OS | 2.35C | No-long-term-NZGHG | 1.5C | Tests system response to rapid emission changes |
| SSP1-1.9 | 1.53C | No-long-term-NZGHG | 1.0C | Sustainable development, no long-term compensation of non-CO2 emissions |
| GS-NZGHG | 1.70C | NZGHG | pre-industrial | Gradual strengthening, returns warming to 1.5 °C by 2215 |
| SP-NZGHG | 1.57C | NZGHG | pre-industrial | Broad shift towards sustainable development |
| Neg-NZGHG | 1.67C | NZGHG | pre-industrial | Returns warming to 1.5 °C by 2100 with heavy CDR deployment |
| Neg-OS-OC | 1.67C | NZGHG | pre-industrial | Returns warming to 1.5 °C by 2100 with heavy CDR deployment |

There is quite a range between the 10 pathways.
At the high end, the “CurPol-OS-1.5C” scenario sees a continuation of the global climate policies implemented in 2020 until the year 2100, with warming peaking at 3.3C. It then sees a decline in global temperature until reaching a stabilisation of 1.5C by the year 2300.
At the low end, “Neg-OS-0C” scenario initially overshoots 1.5C to 1.67C, but then returns warming to 1.5C by 2100 using “heavy carbon dioxide removal deployment”. It also then sees average global temperatures drop to pre-industrial levels by the year 2300.
In the middle, the Ref-1p5 scenario is the only one that does not include an overshoot, instead stabilising quickly at 1.5C.
The chart below shows greenhouse gas emissions (top) and corresponding global temperature changes (bottom) associated with each scenario, identified by the different-coloured lines. The bottom chart illustrates the range in how quickly the pathways return to 1.5C or below.

Dr David McKay is a research impact fellow at the University of Exeter’s Global Systems Institute, who has published extensively on climate tipping points, but was not involved in this study.
He also notes that some of the scenarios shown in this study “may not be possible”, because there is debate about whether or not “the substantial carbon dioxide removal needed for large overshoots is feasible”.
Cascades
Many Earth systems are interlinked, so crossing one tipping point can increase the likelihood of crossing others. This is often described as a “domino effect” or “tipping cascade”.
The study focuses on four interconnected tipping points – collapse of the Greenland ice sheet and west Antarctic ice sheet, shutdown of the Atlantic Meridional Overturning Circulation and dieback of the Amazon rainforest.
Annika Högner is a researcher at the Potsdam Institute for Climate Impact Research (PIK) and co-lead author on the study. She tells Carbon Brief these four tipping points were chosen because they “play a significant role in the functioning of the Earth system” and “their tipping would have severe global impacts”.
The graphic below shows how the tipping points interact with each other. A “+” symbol indicates that crossing one tipping point can destabilise another. For example, a collapse of the Greenland ice sheet makes the AMOC more likely to shut down, as a result of the sudden influx of freshwater into the north Atlantic Ocean. A “±” symbol indicates that the relationship between two tipping points is uncertain.
A “-” symbol indicates that crossing one tipping point stabilises another. Högner tells Carbon Brief that the interaction between the Greenland ice sheet and AMOC is the only stabilising interaction in this study. She explains that if the AMOC were to cross a tipping point, “we [would] expect to see strong cooling in the northern hemisphere”, which will contribute to stabilising the Greenland ice sheet.

Earth system models “often don’t resolve tipping processes very well”, making them less suited to modelling full tipping cascades, Högner tells Carbon Brief.
Instead, she explains that the authors developed a “conceptual model”. This model does not attempt to simulate the entire Earth system, but instead just models the likelihood of tipping at different temperatures, based on existing knowledge about tipping elements from other studies.
The model takes temperature trajectories as an input and gives the state of the tipping elements after a specified time – that is, whether or not the element has tipped – as an output.
Importantly, these models include “hysteresis” – a feature of tipping systems, in which a system that has moved to a different state does not easily move back to the original state even if temperatures are reduced again.
Tipping risk
The authors use their conceptual model to calculate “tipping risk” under the 10 future warming scenarios. Högner tells Carbon Brief that tipping risk “refers to the model of all four interacting tipping elements analysed in the study”. For example, a 50% tipping risk means there is a 50% chance that at least one of the four climate elements will tip.
The top row of the graphic below shows the risk of tipping in the year 2300 (left) and in 50,000 years from now (right). Bars placed higher up indicate a greater likelihood of tipping. The dot shows the average value for each data point, while the bars show the 10-90% range.
The text on the right hand side gives likelihood levels in the calibrated language used by the IPCC: very likely means a likelihood of 90-100%, likely is 66-100%, about as likely as not is 33-66%; unlikely is 0-33%; and very unlikely is 0-10%.
The middle row shows the peak temperature under each scenario (left) and stabilisation temperature (right). The bottom row shows how long temperatures overshoot before stabilising in each scenario.

The longer the 1.5C threshold is breached for, and the higher the peak temperature is, the greater the risk of crossing tipping points by the year 2300, the study shows.
The authors find the greatest risk of crossing tipping points in the CurPol-OS-1.5C scenario (red), which follows the climate policies of 2020 until the year 2100 and then reaches 1.5C by 2300, as this scenario has the greatest overshoot temperature and duration.
Under this scenario, there is a 45% tipping risk by 2300 and a 76% chance in 50,000 years, according to the paper.
The five pathways that do not return warming to 1.5C by the year 2100 have the greatest medium-term risks, and those with less than 0.1C overshoot have the lowest medium-term risks.
In the long-term – looking to the next 50,000 years – the authors find that stabilisation temperature is “one of the decisive variables for tipping risks”. They find that even in the Ref1p5 scenario – which sees global temperatures stabilise at 1.5C without any overshoot – there is a 50% risk of the system tipping over the next 50,000 years.
The results “illustrate that a global mean temperature increase of 1.5C is not ‘safe’ in terms of planetary stability, but must be seen as an upper limit”, the study warns.
Högner tells Carbon Brief that the paper “underlines the importance of adhering to the Paris Agreement temperature goal”.
Tessa Möller – a researcher at the International Institute for Applied Systems Analysis (IIASA) and co-lead author on the paper – tells Carbon Brief that “we have a wide portfolio of technologies available” to limit warming to 1.5C, and just need to “implement” them.
However, she also highlights the “large credibility gap” between pledges from individual countries and the policies they have actually implemented. She tells Carbon Brief that not only do we need “stronger pledges”, but it is also essential that countries follow through on them.
Long-term climate
The authors also explore the risk of each individual tipping point being crossed in different scenarios.
The plot below shows the tipping risk by 2300 under different scenarios, at different temperatures, on the left. Each colour represents one scenario. Dots positioned further to the right indicate a greater peak temperature and dots positioned higher up indicate a greater tipping risk.
The plot on the right shows the percentage change in tipping risk for every additional 0.1C of overshoot, for different peak global temperatures, for the Amazon (cross), AMOC (plus), West Antarctic ice sheet (black dot) Greenland Ice sheet (square) and overall (yellow dot).

The authors find that AMOC collapse and Amazon dieback would likely be the first components to tip. This could be in the next 15-300 years and 50-200 years, respectively, depending on the scenario, they find.
Meanwhile, the Greenland and west Antarctic ice sheets have tipping timescales of 1,000-15,000 years and 500-13,000 years, respectively.
However, they note that as temperatures increase, the relative risk of each element tipping changes. The graph shows that while AMOC is the main driver of tipping risk at lower temperatures, the Amazon becomes the main driver once global temperatures exceed 2C.
Finally, they find that as global temperatures rise, the risk of tipping accelerates. Overall, tipping risk increases by 1-1.5% per 0.1C increase in overshoot temperature, for temperatures below 2C, according to the study. However, above 2.5C, tipping risk increases to 3% per 0.1C increase overshoot.
McKay notes that there are some limitations in the study. For example, he notes that the paper “has to rely on tipping threshold and timescale estimates with often wide ranges and sometimes low confidence, while tipping interaction estimates are based on dated expert judgement”.
However, he adds:
“This work makes it clear that every fraction of warming increases the chance of tipping points, even if global temperature subsequently falls, and underlines the need for urgent emission cuts now that do not assume substantial carbon dioxide removal later.”

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.

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”.

Climate Change
Q&A: How will the World Bank’s abandoned finance goal affect climate action?
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.”

Climate Change
As food shocks spread, citizens are showing more leadership than governments
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.
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.
