UK chancellor Rachel Reeves has unveiled the first spending review under the current Labour government, announcing funding for nuclear power, energy efficiency and carbon capture and storage (CCS).
A spending review establishes each ministry’s spending limits and priorities for the rest of the parliamentary term.
The Department of Energy Security and Net Zero (DESNZ) received one of the largest jumps in capital spending, despite energy secretary Ed Miliband reportedly being one of the last to agree to a spending settlement.
Before the final details had been announced, the Times was describing Miliband as one of the “biggest winners” from the process.
High-profile funding announcements in the Treasury’s spending review include £14.2bn for the Sizewell C new nuclear power plant in Suffolk, the first state-backed nuclear power station for decades.
Elsewhere, two new CCS clusters – Acorn and Viking – were allocated funding and railways across the nation were given a boost.
Below, Carbon Brief runs through the key announcements.
- Departmental spending
- Energy efficiency
- Energy infrastructure investment
- Transport
- Other announcements
Departmental spending
Spending reviews are an opportunity for governments to stake out their priorities by setting the budgets for departments over the rest of this parliament.
Reeves’ spending review has been viewed by experts and media commentators as an opportunity to boost Labour’s flagging popularity and pursue some of its key manifesto commitments, including net-zero.
It covers plans for departmental “resource” spending – including day-to-day running costs – out to 2028-29 and “capital” spending out to 2029-30.
The latter includes injections of funding for infrastructure and public services, such as major clean-energy and transport projects.
In her speech launching the review, Reeves did not specifically mention the terms net-zero or climate change, but stressed the importance of achieving energy security via domestic, low-carbon power. “Clean energy” also featured prominently in the review document itself.
Overall, total departmental budgets are set to grow by 2.3% in real terms across the spending review period.
The Department for Energy Security and Net Zero (DESNZ) is expected to see a 16% increase in overall departmental spending, reaching £12.6bn in 2028-29.
(This does not include the boost in funding for Sizewell C nuclear plant, which will see a 15.6% increase thanks to a £14.2bn investment over the next five years. See: New nuclear.)
The chart below – taken from the spending review document – shows that while the absolute increase in spending on areas such as health, defence and education is higher, DESNZ is among the most highly prioritised in relative terms.
The review document emphasises that this increase in public money is necessary to mobilise private investment and “secure the UK’s electricity system with homegrown, clean power by 2030”.
Other departments that are also relevant for climate action have not seen the same overall increases in budget.
The Department for Transport (DfT) is set to see its overall departmental spending drop by 0.4%. However, the review notes that capital spending will increase, including more money for local low-carbon transport options and major rail projects.
The Department for Environment, Food and Rural Affairs (Defra) budget is also expected to fall overall, but support for “nature-friendly farming” is set to more than double over the review period.
Energy efficiency
Leading up to the spending review, there had been speculation that the government might cut plans to invest £13.2bn on upgrading the nation’s homes under its “warm homes plan”, which had been a manifesto commitment ahead of last year’s election.
Such a move could have cost households more than £1.4bn a year in avoidable energy bills, according to analysis from thinktank the Energy and Climate Intelligence Unit (ECIU).
However, the spending review confirmed the pledged £13.2bn in funding for the scheme, covering spending between 2025-26 and 2029-30.
The government says this will help to cut bills by up to £600 per household through energy efficiency measures, heat pumps, solar panels and batteries. It will also help support tens of thousands of jobs across the country, the spending review adds.
According to innovation agency Nesta, the warm homes funding is roughly double the previous government’s commitment, amounting to a £6.6bn increase in government spending on home upgrades over the current parliament, compared with the previous one.
It will see around one-fifth of the nation’s housing stock upgraded by 2029, although to a varying degree.
Responding to the announcement, trade association Energy UK’s chief executive Dhara Vyas said in a statement:
“It’s also very important that millions of customers will see a direct benefit from today’s announcements. By reaffirming the funding to improve the energy efficiency of millions of homes and supporting the switch to cleaner heating alternatives, customers can expect warmer and more comfortable homes, cleaner air and cheaper bills – showing how the energy transition can improve their daily lives.”
Funding for the warm homes plan in the spending review follows £3.4bn in investment announced for the scheme at the autumn budget in 2024. At the time, Labour had said that this was just the “first step” in investment for decarbonisation and household energy efficiency within the scheme.
Further details for the warm homes plan will be confirmed in October, the spending review says.
Beyond energy efficiency, Reeves announced what she called the “biggest boost to investment in social and affordable housing in a generation”, confirming £39bn in funding for a 10-year affordable homes programme.
This will nearly double government spending on affordable housing, according to reporting earlier this week.
Miliband recently announced changes to the “future homes standard” that will mean almost all new homes will have to be built with rooftop solar as a default, high levels of energy efficiency and low-carbon heating, such as heat pumps.
As such, new properties built under the affordable homes programme will largely have to include energy efficiency measures and low-carbon energy technologies.
Energy infrastructure investment
GB Energy
The spending review also confirms that it will allocate £8.3bn in funding for Great British Energy (GB Energy) and the linked GB Energy – Nuclear, another manifesto commitment.
It says this has been achieved by allocating £9.6bn in “additional financial transactions, such as loans and equity investments, to support growth”.
(It explains that “financial transactions” are designed to “allow government to invest alongside the private sector, through equity investments, loans and guarantees”. The document also says that GB Energy will be designated as a “public financial institution”.)
In addition to this top-line confirmation for GB Energy, the spending review also gives it an extra £300m in support for offshore wind supply chains.
This forms part of the “government’s investment in resilient and clean energy security, boosting domestic jobs, mobilising additional private investment and securing manufacturing facilities for critical clean energy supply chains such as floating offshore platforms”, it notes.
The spending review confirms up to £80m for port investment to support floating offshore wind deployment in Port Talbot in Wales, subject to final due diligence.
GB Energy funding follows on from Labour’s manifesto, promising investment into technologies such as floating offshore wind, as well as partnering with local authorities and the private sector to support the deployment of mature technologies.
New nuclear
Ahead of the spending review, the chancellor announced a £14.2bn investment in the planned Sizewell C new nuclear power plant in Suffolk.
The plant is being jointly developed by the UK government with French state-owned utility firm EDF Energy, which is already building the Hinkley C plant in Somerset.
Each new plant will have a capacity of 3.2 gigawatts (GW), enough to power six million homes. During its construction, Sizewell C will provide 10,000 jobs, including 1,500 apprenticeships, according to the government.
In a statement earlier this week, energy secretary Ed Miliband said new nuclear was needed for energy security, lower bills and to help cut emissions. He said:
“We need new nuclear to deliver a golden age of clean-energy abundance, because that is the only way to protect family finances, take back control of our energy, and tackle the climate crisis.
“This is the government’s clean energy mission in action- investing in lower bills and good jobs for energy security.”
Speaking on BBC Radio 4’s Today programme following the investment announcement, Miliband stated that China would not be able to invest in the new nuclear plant in Suffolk. He further clarified that, while the majority of the investment would come from the UK government, there will also be private investment announced at a later date.
Sizewell C will be one of the first new nuclear power stations in the UK in decades, with no new nuclear power plants having opened since 1995 and all but one of the existing fleet expected to retire by the early 2030s.
The under-construction plant at Hinkley Point C is also being developed by EDF and is expected to serve as a “blueprint” for Sizewell C.
The Hinkley C plant is being funded via a “contract for difference” (CfD), under which EDF is responsible for the upfront investment costs, but will receive £92.50 per megawatt hour (MWh, 2012 prices) for each unit of electricity generated. (This will drop to £89.50/MWh in 2012 prices as a result of the Sizewell C project going ahead.)
EDF has reportedly accepted that Hinkley C will cost more than £40bn to complete, but has “rejected claims” that the Sizewell C scheme would cost a similar amount.
Sizewell C is due to be funded under the “regulated asset base” (RAB) model and so will not receive a CfD, but the details of this deal are not yet available. The final investment decision on the project is due later this summer, according to reports.
Additionally, the government announced Rolls-Royce has been selected to build small modular nuclear reactors (SMRs) following a “rigorous” two-year competition.
Rolls-Royce will partner with Great British Energy – Nuclear as part of the government’s industrial strategy, which will see £2.5bn invested over the spending review period.
The firm is expected to build three SMRs, with the first connecting to the grid “in the mid-2030s”, according to Rolls-Royce.
The spending review also included over £2.5bn for nuclear fusion. This will include support for the design and build of a prototype energy plant in Nottinghamshire.
The document notes that the government is providing a “pathway for privately led advanced nuclear technologies”, although details are not elaborated.
Great British Energy – Nuclear will shortly publish a new framework with the National Wealth Fund for exploring further investment opportunities for viable nuclear projects.
The spending review includes £13.9bn for the Nuclear Decommissioning Authority, to keep “former nuclear sites and facilities safe and secure as it decommissions sites and manages nuclear waste”.
Carbon capture and storage
The UK has already pledged “up to” £21.7bn of funding over 25 years to support five carbon capture and storage (CCS) projects, involving “clusters” of connected facilities.
Most of this funding will come from levies on consumers, but the government has also been gradually announcing chunks of public investment to get these initiatives off the ground.
The spending review allocates another £9.4bn of capital spending by 2029. This will partly go towards “maximis[ing] deployment to fill the [CO2] storage capacity” of the first two funded clusters.
At the same time, the government also confirmed its support for the next two clusters – Acorn in north-east Scotland and Viking in the Humber in the spending review. These projects are set to be up and running in the 2030s.
The review states that the government is providing the “development funding to advance [the] delivery” of these clusters, with a final investment decision expected “later this parliament, subject to project readiness and affordability”.
Pathways set out by government advisors at the Climate Change Committee (CCC) suggest CCS is required to meet the UK’s net-zero targets.
However, the government has faced intense scrutiny over its investments in CCS. A report by the influential Public Accounts Committee earlier this year said investing public funds in this relatively undeveloped technology was a “high risk” approach.
Transport
The spending review includes a number of commitments for regional transport projects that could help cut UK emissions, including rail upgrades, bus lanes and cycleways.
Overall, the Department for Transport (DfT) settlement will reach total funding of £31.5bn in 2028-29, a slight increase from current levels. This includes support for the HS2 high-speed rail project.
HS2, which had its second phase out to Manchester cancelled under the Conservatives in 2023, will see its funding drop over the spending period.
Meanwhile, capital spending on transport projects around the country is set to experience a 4% real-terms growth rate each year out to 2029-30.
Regional transport projects receiving funding include the TransPennine Route Upgrade between York and Manchester, with £3.5bn, as well as £2.5bn for East-West Rail between Oxford and Cambridge and £300m for rail investment in Wales.
(For comparison, despite the declining funds, HS2 will receive £25.3bn over the period.)
Other relevant investments in the spending review include a commitment to “more than double” city region transport spending per year by 2029-30, by providing a total of £15.6bn for elected mayors across England. The review says this could go towards local transport priorities, including “zero-emission buses, trams and local rail”.
Additionally, there is another £2.3bn allocated for investment in local transport grants to support “bus lanes, cycleways and congestion improvement measures” for areas outside the larger regions with mayors.
The review includes a relatively small sum – £2.6bn – of capital investment that is set aside to “decarbonise transport” as “part of the government’s clean energy mission”.
This is made up of £1.4bn to “support continued uptake” of electric vehicles, in particular vans and heavy goods vehicles (HGVs), as well as £400m for charging infrastructure and £616m for walking and cycling infrastructure.
Some of these funds will also support the production of “sustainable” aviation fuel (SAF) in the UK by extending the government’s advanced fuels fund.
The spending review also includes funding for transport projects that may not help to decarbonise the nation’s transport. Notably, there is £24bn of funding by 2030 to “maintain and improve motorways and local roads across the country”.
Also, while the project is not mentioned in the spending review document itself, Reeves’s speech mentioned “backing Doncaster airport” alongside “investment to connect our cities and our towns”. (The airport is currently closed, but there has been a local political effort to reopen it.)
Other announcements
R&D funding
The government is increasing research and development (R&D) funding to £22.6bn per year by 2029-2030.
This will include funding for the UK’s science base, the spending review says, such as the non-departmental public body UK Research and Innovation and research initiative Horizon Europe.
Part of this funding will go to the government’s new R&D missions accelerator programme. Some £500m of public funds are intended to leverage a further £1.5bn of private investment in innovation that supports the government’s “missions”.
(One of the five key “missions” announced by the Labour government in its manifesto is to “make Britain a clean-energy superpower”.)
Additionally, R&D funding will include up to £750m for a new supercomputer at Edinburgh University, the largest in the UK. This will be used to support a broad range of fields, including climate and weather predictions and research into fusion power.
In a statement, secretary of state for Scotland Ian Murray welcomed the funding for the supercomputer, adding:
“This will see Scotland playing a leading role in creating breakthroughs that have a global benefit – such as new medicines, health advances and climate change solutions.”
Ahead of the publication of the delayed UK industrial strategy, the spending review lists relevant R&D commitments.
It says over £3bn in R&D and capital funding over the next four years will go to advanced manufacturing across the UK, “anchoring the supply chain of zero emission vehicles, batteries and ultra-low and zero-carbon emissions aircraft[s]”.
Clean-energy industries will also receive “significant additional funding”, it adds.
Flood defences and farming funds
As part of the spending review, the government announced investment in climate adaptation and the natural environment to “increase the UK’s resilience to the effects of climate change and protect the ecosystems that underpin the economy and food security”.
This includes £2.7bn in sustainable farming and nature recovery funding until 2028-29, as well as £4.2bn to build and maintain flood defences from 2026-27 to 2028-29.
According to the spending review, farmers will benefit from £2.3bn through the farming and countryside programme and up to £400m from additional nature schemes
There will be increasing support for “nature-friendly farming” through environmental land management schemes, which will grow from £800m in 2023-24 to £2bn by 2028-29. This will be sustained by “rapidly winding down” other subsidy payments.
The spending review states that this will make a “significant contribution” to the Environment Act targets, including improvements to water and air quality and creating spaces for wildlife to support biodiversity.
Funding for both flood defences and farm schemes follows the government stating that it was facing “significant funding pressures” of almost £600m in 2024-25 in the autumn budget.
Foreign aid and climate finance
The government announced in February that it would further cut aid spending to 0.3% of gross national income (GNI) by 2027 in order to fund higher defence spending.
This came just three months after the UK, alongside other developed countries, had committed to raising at least $300bn a year for climate action in developing countries at the COP29 climate summit.
Developed countries have traditionally used their aid budgets to meet such “climate finance” goals.
But observers have noted that scaling up climate finance to meet this new target will be difficult, as nations cut back their overseas spending and the world faces overlapping humanitarian crises.
When announcing the cut earlier this year, prime minister Keir Starmer said that the UK would retain its focus on “tackling climate change” in its aid spending. The government also acknowledged that the decision to cut aid would require “many hard choices”.
The government has a pledge to spend £11.6bn over five years on climate finance in developing countries, which ends in 2025-26. Beyond that, it is expected to announce a new pledge to feed into the $300bn goal.
The spending review does not provide details of precisely what this goal will be, or whether it will be more ambitious as other aid programmes undergo swingeing cuts.
It states that the funding plan “prioritises UK multilateral investment across issues where the international system needs to deliver at scale and to reform”, including the “climate and nature crisis”.
It also says the three departments that provide nearly all UK climate finance – the Foreign, Commonwealth and Development Office, DESNZ and Defra – will “maintain progress” on the nation’s international climate goals.
However, the amounts of aid channelled via all three of these departments will be lower in the coming years than they are now, according to the government’s figures.
Response to climate-risks report
In a separate document published alongside the spending review, the government also set out its response to the latest “fiscal risks and sustainability” (FRS) report, published by the Office for Budget in September 2024.
Within this, the government reiterates its intention to “accelerate to net-zero”, including via its target for clean power by 2030.
The response adds that, alongside this, the government recognises that it “must also take action to build resilience and ensure the UK is well-prepared for the changing climate”.
It says that FRS identified flooding and extreme heat as areas that need particular attention, before setting out its spending commitments in these areas.
The response also confirms two important dates for UK climate-policy watchers.
First, the response says the government will, in October 2025, publish its “carbon budget delivery plan”. This will set out the plans and policies the government will put in place in order to meet the first six carbon budgets, covering the years out to 2037.
Second, it says that the government will legislate for the seventh UK “carbon budget” by June 2026. This is a legally binding limit on emissions covering five years from 2038 to 2042. The CCC has recommended an 87% reduction below 1990 levels.

DeBriefed 14 November 2025: COP30 DeBriefed: Finance and 1.5C loom large at talks; China’s emissions dip; Negotiations explained
Welcome to Carbon Brief’s DeBriefed.
An essential guide to the week’s key developments relating to climate change.
This week
Finance and 1.5C dominate talks
AGENDA ADOPTED: Negotiations at the COP30 UN climate talks began in the Brazilian city of Belém this week, attended in person by Carbon Brief’s Daisy Dunne, Josh Gabbatiss and Anika Patel. The Brazilian hosts scored an unexpected early win by dodging an “agenda fight” over proposals to add various contentious issues to the official docket. Despite the neat footwork, four issues kept off the agreed agenda – climate finance; emissions reporting; trade measures; ambition and 1.5C – still loom large, having merely been diverted into “presidency consultations”.
PRESIDENCY PROMISES: By Wednesday, the presidency was promising “good news” at a plenary later that day, which had been due to offer an update on progress with the four extra items. Instead, it ended abruptly, with COP30 president André Corrêa do Lago promising to say more at another plenary scheduled for tomorrow. It remains unclear how the presidency intends to deal with these thorny issues, leaving the COP rumour-mill in full swing.
MINISTERIAL MAGIC: Aside from the extra issues, the official agenda at COP30 already has more than 100 items to contend with, including how to track progress on adaptation and how to ensure a “just transition” as emissions-cutting measures are implemented. (You can follow them all via the Carbon Brief text tracker.) While draft texts have started to emerge, many items remain stalled, with persistent divisions along familiar lines (see below). Negotiators will be hoping that ministers arriving over the weekend are primed to unlock progress. Brazil has appointed pairs of these politicians to push for deals in key areas.
Around the world
- Ethiopia has said it will host COP32 after beating out a bid from Nigeria, Reuters reported. Turkey and Australia are still in deadlock over who should host COP31, with a decision due by the end of these talks, BBC News reported.
- China will not contribute to Brazil’s Tropical Forest Forever Facility, Bloomberg reported, while Devex said two multilateral development banks are considering paying in. More than $5.5bn has been pledged so far, which BusinessGreen noted is “well short” of a $25bn target. The fund was labelled a “false solution” by some Indigenous and civil society groups.
- After Brazilian president Luiz Inácio Lula da Silva called for a “roadmap” away from fossil fuels ahead of COP’s opening, rumours are swirling over how this might take shape. A new declaration spearheaded by Colombia and a roadmap with backing from a number of countries, including Denmark, the UK, France, Kenya and Germany, are being floated as possible options.
- China is currently among the countries pushing for “provision of finance from rich countries and unilateral trade measures” to be included on the agenda, reported Climate Home News. Chinese delegation head Li Gao told Agence France-Presse it is “crucial” for developed countries to fulfil their $300bn commitment.
- Dozens of Indigenous protesters forced their way into COP’s blue zone on Tuesday night, expressing anger at a lack of access to the negotiations, Reuters said. On Friday, a peaceful protest blocked the entrance to the blue zone, causing lengthy queues as delegates were forced to use a side door.

Captured
China’s carbon dioxide emissions have “now been flat or falling for 18 months” since March 2024, analysis for Carbon Brief has found, due, in particular, to the transport, cement and steel sectors. The analysis has been covered widely in publications including China’s Global Times, the New York Times, Financial Times, Reuters, Bloomberg and on the frontpage of the Guardian.
Spotlight
What to expect from COP30 talks
This week, Carbon Brief’s expert team walk through what is happening with the biggest issues being negotiated at COP30.
‘Cover text’
Can you judge a COP by its cover text? At COP, the presidency has the option to pull together a new negotiated “cover text”, an overarching political overview of decisions agreed at the summit, along with other issues not on the agenda that it wants to draw attention to.
COP30 president André Corrêa do Lago might have dismissed a catch-all “cover decision” as a “last-minute solution” ahead of COP and dodged the question since, but other parties have been less shy in hinting that a cover text is, indeed, coming.
Cover decisions are often the product of fraught negotiations, high stakes, too little time and too many parties to accommodate.
This year, there is added pressure to address what is happening in the wider world outside the “negotiations” and to politically signal that the UN climate process is alive and making progress, despite the withdrawal of the US.
What elements could go into it? As a member of the “BASIC” group of nations comprising Brazil, South Africa, India and China, trade measures could find a place. But ideas pushed by Brazilian president Lula for new “roadmaps” away from fossil fuels and deforestation might find a place. Finance, however, could be much trickier to fit in.
Adaptation
One of the key expected outcomes of COP30 is agreement on a list of 100 indicators that can be used to measure progress under the “global goal on adaptation” (GGA). After two years of work by experts, negotiations got underway with a suggested list that had been whittled down from nearly 10,000 possible indicators.
Despite the focus on the GGA by the COP30 presidency and others, division has quickly emerged around the timeline for the adoption of the indicators. The African Group has notably requested a two-year work programme to further refine the list, while other parties are pushing for the indicators to be adopted in Belém as planned.
On Wednesday, an informal note was published that compiled elements for a draft decision. Significantly, for the first time under the GGA, this included a call for developed countries to “at least triple their collective provision” of adaptation finance by 2030, with a target to reach $120bn. This echoed a suggested target originally set out by the negotiating group of least developed countries (LDCs), supported by the African Group, Arab Group and the Association of Latin America and the Caribbean (AILAC) countries.
Just transition and mitigation work programmes
Over the past year, civil society groups have been calling for the establishment of a mechanism to enact the agreed UNFCCC principles of a “just transition”. This gained momentum on Wednesday within negotiations of the just transition work programme (JTWP), when the G77 and China called for the development of the “Belem Action Mechanism” (BAM).
Chile, the Alliance of Small Island States (AOSIS), India and other developing countries supported the mechanism. However, Norway, the UK, Australia and Japan pushed back. Other long-standing points of contention have also raised their heads, including around unilateral trade measures and references to fossil fuels and aligning to global temperature goals.
Within the mitigation work programme (MWP) talks, negotiators are looking to build on two dialogues held this year. The main themes at COP30 are the links between the MWP and the global stocktake (see below) and the future of the programme itself.
Old divisions have emerged in negotiations, focused predominantly on the mandate of the MWP and the potential development of a digital platform as part of its continuation.
UAE dialogue
The landmark outcome of the first “global stocktake”, agreed at COP28 in Dubai, called on all countries to contribute to a “transition away from fossil fuels”. It also mandated a “UAE dialogue” on “implementing the global stocktake outcomes”.
Two years later, countries remain deadlocked over what this dialogue should discuss. Many want it to cover all parts of the stocktake, including the energy transition, while others want an exclusive focus on climate finance. They also disagree on whether the dialogue should have substantive outcomes, including a formal process to keep discussing the issues raised.
Having failed to reach agreement at COP29 last year, the latest draft text shows parties are just as far apart in Belém, nearly halfway into the summit.
Finance
Climate finance for developing countries does not occupy a high-profile position in the formal COP30 negotiations. Yet, as demonstrated by its role in adaptation talks and the agenda dispute, finance still has the potential to derail proceedings.
Ahead of the conference, the COP30 and COP29 presidencies released their “Baku to Belém roadmap”, exploring how finance could be ramped up to $1.3tn by 2035.
An influential group of experts also released new analysis showing a “feasible path” to this goal, leaning on private finance. They said this work would provide a “valuable signal” to those in the finance sector.
However, with no position in the Belém negotiations, it was unclear how – or whether – the roadmap would be taken forward by governments beyond COP30.
Instead, finance negotiators have been occupied with technical matters, but these still show signs of division. For example, some developing-party groups have pushed back against an EU priority goal to extend a “dialogue” about “making finance flows consistent” with climate objectives.

Developed countries have poured billions of dollars into railways across Asia, solar projects in Africa and thousands of other climate-related initiatives overseas, according to a joint investigation by Carbon Brief and the Guardian.
A group of nations, including much of Europe, the US and Japan, is obliged under the Paris Agreement to provide international “climate finance” to developing countries.
This financial support can come in forms such as grants and loans from various sources, including aid budgets, multilateral development banks (MDBs) and private investments.
The flagship climate-finance target for more than a decade was to hit “$100bn a year” by 2020, which developed countries met – albeit two years late – in 2022.
Carbon Brief and the Guardian have analysed data across more than 20,000 global climate projects funded using public money from developed nations, including official 2021 and 2022 figures, which have only just been published.
The data provides a detailed insight into how the $100bn goal was reached, including funding for everything from sustainable farming in Niger to electricity projects in the United Arab Emirates (UAE).
With developed countries now pledging to ramp up climate finance further, the analysis also shows how donors often rely on loans and private finance to meet their obligations.
- The $100bn target was reached in 2022, boosted by private finance and the US
- Relatively wealthy countries – including China and the UAE – were major recipients
- A tenth of all direct climate finance went to Japan-backed rail projects
- There was funding for more than 500 clean-power projects in African countries
- Some ‘least developed’ countries relied heavily on loans
- US shares in development banks significantly inflated its total contribution
- Adaptation finance still lags, but climate-vulnerable countries received more
- Methodology
The $100bn target was reached in 2022, boosted by private finance and the US
A small handful of countries have consistently been the top climate-finance donors. This remained the case in 2021 and 2022, with just four countries – Japan, Germany, France and the US – responsible for half of all climate finance, the analysis shows.
Not only was 2022 the first year in which the $100bn goal was achieved, it also saw the largest ever single-year increase in climate finance – a rise of $26.3bn, or 29%, according to the Organisation for Economic Cooperation and Development (OECD).
(It is worth noting that while OECD figures are often referenced as the most “official” climate-finance totals, they are contested.)
Half of this increase came from a $12.6bn rise in support from MDBs – financial institutions that are owned and funded by member states. The rest can be attributed to two main factors.
First, while several donors ramped up spending, the US drove by far the biggest increase in “bilateral” finance, provided directly by the country itself.
After years of stalling during the first Donald Trump presidency, when Joe Biden took office in 2021, the nation’s bilateral climate aid more than tripled between that year and the next.
Meanwhile, after years of “stagnating” at around $15bn, the amount of private investments “mobilised” in developing countries by developed-country spending surged to around $22bn in 2022, according to OECD estimates.
As the chart below shows, the combination of increased US contributions and higher private investments pushed climate finance up by nearly $14bn in 2022, helping it to reach $115.9bn in total.
Both of these trends are still pertinent in 2025, following a new pledge made at COP29 by developed countries to ramp up climate finance to “at least” $300bn a year by 2035.
After years of increasing rapidly under Biden, US bilateral climate finance for developing countries has been effectively eliminated during Trump’s second presidential term. Other major donors, including Germany, France and the UK, have also cut their aid budgets.
This means there will be more pressure on other sources of climate finance in the coming years. In particular, developed countries hope that private finance can help to raise finance into the trillions of dollars required to achieve developing countries’ climate goals.
Some higher-income countries – including China and the UAE – were major recipients
The greatest beneficiaries of international climate finance tend to be large, middle-income countries, such as Egypt, the Philippines and Brazil, according to the analysis.
(The World Bank classifies countries as being low-, lower-middle, upper-middle or high-income, according to their gross national income per person.)
Lower-middle income India received $14.1bn in 2021 and 2022 – nearly all as loans – making it by far the largest recipient, as the chart below shows.
Most of India’s top projects were metro and rail lines in cities, such as Delhi and Mumbai, which accounted for 46% of its total climate finance in those years, Carbon Brief analysis shows. (See: A tenth of all direct climate finance went to Japan-backed rail projects.)
As the world’s second-largest economy and a major funder of energy projects overseas, China – classified as upper-middle income by the World Bank – has faced mounting pressure to start officially providing climate finance. At the same time, the nation received more than $3bn of climate finance over this period, as it is still classed as a developing country under the UN climate system.
High-income Gulf petrostates are also among the countries receiving funds. For example, the UAE received Japanese finance of $1.3bn for an electricity transmission project and a waste-to-energy project.
To some extent, such large shares simply reflect the size of many middle-income countries. India received 9% of all bilateral and multilateral climate finance, but it is home to 18% of the global population.
The focus on these nations also reflects the kind of big-budget infrastructure that is being funded.
“Middle-income economies tend to have the financial and institutional capacity to design, appraise and deliver large-scale projects,” Sarah Colenbrander, climate programme director at global affairs thinktank ODI, tells Carbon Brief.
Donors might focus on relatively higher-income or powerful nations out of self-interest, for example, to align with geopolitical, trade or commercial interests. But, as Colenbrander tells Carbon Brief, there are also plenty of “high-minded” reasons to do so, not least the opportunity to help curb their relatively high emissions.
A tenth of all direct climate finance went to Japan-backed rail projects
Japan is the largest climate-finance donor, accounting for a fifth of all bilateral and multilateral finance in 2021 and 2022, the analysis shows.
Of the 20 largest bilateral projects, 13 were Japanese. These include $7.6bn of loans for eight rail and metro systems in major cities across India, Bangladesh and the Philippines.
In fact, Japan’s funding for rail projects was so substantial that it made up 11% of all bilateral finance. This amounts to 4% of climate finance from all sources.
While these rail projects are likely to provide benefits to developing countries, they also highlight some of the issues identified by aid experts with Japan’s climate-finance practices.
As was the case for more than 80% of Japan’s climate finance, all of these projects were funded with loans, which must be paid back. Nearly a fifth of Japan’s total loans were described as “non-concessional”, meaning they were offered on terms equivalent to those offered on the open market, rather than at more favourable rates.
Many Japan-backed projects also stipulate that Japanese companies and workers must be hired to work on them, reflecting the government’s policies to “proactively support” and “facilitate” the overseas expansion of Japanese business using aid.
Documents show that rail projects in India and the Philippines were granted on this basis.
This practice can be beneficial, especially in sectors such as rail infrastructure, where Japanese companies have considerable expertise. Yet, analysts have questioned Japan’s approach, which they argue can disproportionately benefit the donor itself.
“Counting these loans as climate finance presents a moral hazard…And such loans tied to Japanese businesses make it worse,” Yuri Onodera, a climate specialist at Friends of the Earth Japan, tells Carbon Brief.
There was funding for more than 500 clean-power projects in African countries
Around 730 million people still lack access to electricity, with roughly 80% of those people living in sub-Saharan Africa.
As part of their climate-finance pledges, donor countries often support renewable projects, transmission lines and other initiatives that can provide clean power to those in need.
Carbon Brief and the Guardian have identified funding for more than 500 clean-power and transmission projects in African countries that lack universal electricity access. In total, these funds amounted to $7.6bn over the two years 2021-22.
Among them was support for Chad’s first-ever solar project, a new hydropower plant in Mozambique and the expansion of electricity grids in Nigeria.
The distribution of funds across the continent – excluding multi-country programmes – can be seen in the map below.
A lack of clear rules about what can be classified as “climate finance” in the UN climate process means donors sometimes include support for fossil fuels – particularly gas power – in their totals.
For example, Japan counted an $18m loan to a Japanese liquified natural gas (LNG) company in Senegal and roughly $1m for gas projects in Tanzania.
However, such funding accounted for a tiny fraction of sub-Saharan Africa’s climate finance overall, amounting to less than 1% of all power-sector funding across the region, based on the projects identified in this analysis.
Some ‘least developed’ countries relied heavily on loans
One of the most persistent criticisms levelled at climate finance by developing-country governments and civil society groups is that so much of it is provided in the form of loans.
While loans are commonly used to fund major projects, they are sometimes offered on unfavourable terms and add to the burden of countries that are already struggling with debt.
The International Institute for Environment and Development (IIED) has shown that the 44 “least developed countries” (LDCs) spend twice as much servicing debts as they receive in climate finance.
Developed nations pledged $33.4bn in 2021 and 2022 to the 44 LDCs to help them finance climate projects. In total, $17.2bn – more than half of the funding – was provided as loans, primarily from Japan, France and development banks.
The chart below shows how, for a number of LDCs, loans continue to be the main way in which they receive international climate funds.
For example, Angola received $216.7m in loans from France – primarily to support its water infrastructure – and $571.6m in loans from various multilateral institutions, together amounting to nearly all the nation’s climate finance over this period.
Oxfam, which describes developed countries as “unjustly indebting poor countries” via loans, estimates that the “true value” of climate finance in 2022 was $28-35bn, roughly a quarter of the OECD’s estimate. This is largely due to Oxfam discounting much of the value of loans.
However, Jan Kowalzig, a senior policy adviser at Oxfam Germany, tells Carbon Brief that, “generally, LDCs receive loans at better conditions” than they would have been able to secure on the open market, sometimes referred to as “concessional” loans.
US shares in development banks significantly raised its total contribution
The US has been one of the world’s top climate-finance providers, accounting for around 15% of all bilateral and multilateral contributions in 2021 and 2022.
Despite this, US contributions have consistently been viewed as relatively low when considering the nation’s wealth and historical role in driving climate change.
Moreover, much of the climate finance that can be attributed to the US comes from its MDB shareholdings, rather than direct contributions from its aid budget.
These banks are owned by member countries and the US is a dominant shareholder in many of them.
The analysis reveals that around three-quarters of US climate finance provided in 2021-22 came via multilateral sources, particularly the World Bank. (For information on how this analysis attributes multilateral funding to donors, see Methodology.)
Among other major donors – specifically Japan, France and Germany – only a third of their finance was channelled through multilateral institutions. As the chart below shows, multilateral contributions lifted the US from being the fifth-largest donor to the third-largest.
While the Trump administration has cut virtually all overseas climate funding and broadly rejected multilateral institutions, the US has not yet abandoned its influential stake in MDBs.
Prior to COP29 in 2024, only MDB funds that could be attributed to developed country inputs were counted towards the $100bn goal, as part of those nations’ Paris Agreement duties.
However, countries have now agreed that “all climate-related outflows” from MDBs – no matter which donor country they are attributed to – will count towards the new $300bn goal.
This means that, as long as MDBs continue extensively funding climate projects, there will still be a large slice of climate finance that can be attributed to the US, even as it exits the Paris Agreement.
Adaptation finance still lags, but climate-vulnerable countries received more
Under the Paris Agreement, developed countries committed to achieving “a balance between adaptation and mitigation” in their climate finance.
The idea is that, while it is important to focus on mitigation – or cutting emissions – by supporting projects such as clean energy, there is also a need to help developing countries prepare for the threat of climate change.
Generally, adaptation projects are less likely to provide a return on investment and are, therefore, more reliant on grant-based finance.
In practice, a “balance” between adaptation and mitigation has never been reached. Over the period of this analysis, 58% of climate finance was for mitigation, 33% was for adaptation and the remainder was for projects that contributed to both goals.
This reflects a preference for mitigation-based financing via loans among some major donors, particularly Japan and France. Both countries provided just a third of their finance for adaptation projects in 2021 and 2022.
However, among some of the most climate-vulnerable countries – including land-locked parts of Africa and small islands – most funding was for adaptation, as the chart below shows.
Among the projects receiving climate-adaptation funds were those supporting sustainable agriculture in Niger, improving disaster resilience in Micronesia and helping those in Somalia who have been internally displaced by “climate change and food crises”.
Methodology
The joint Guardian and Carbon Brief analysis of climate finance includes the bilateral and multilateral public finance that developed countries pledged for climate projects in developing countries. It covers the years 2021 and 2022.
(These “developed” countries are the 23 “Annex II” nations, plus the EU, that are obliged to provide climate finance under the Paris Agreement.)
The analysis excludes other types of funding that contribute to the $100bn climate-finance target for climate projects, such as export credits and private finance “mobilised” by public investments. Where these have been referenced, the figures are OECD estimates. They are excluded from the analysis because export credits are a small fraction of the total, while private finance mobilised cannot be attributed to specific donor countries.
Data for bilateral funding comes from the biennial transparency reports (BTRs) each country submits to the UNFCCC. The lag in official reporting means the most recent figures – published around the end of 2024 and start of 2025 – only go up to 2022.
Many of the bilateral projects recorded by countries do not specify single recipients, but instead mention several countries. These projects have not been included when calculating the amount of finance individual developing countries received, but they are included in the total figures.
The multilateral funding, including projects funded by MDBs and multilateral climate funds, comes from the OECD. Many countries – including developing countries – pay into these institutions, which then use their money to fund climate projects and, in the case of MDBs, raise additional finance from capital markets.
This analysis calculated the shares of the “outflows” from multilateral institutions that can be attributed to developed countries. It adapts the approach used by the OECD to calculate these attributable shares for developed countries as a whole group.
As the OECD does not publish individual donor country shares that make up the total developed-country contribution, this analysis calculated each country’s attributable shares based on shareholdings in MDBs and cumulative contributions to multilateral funds. This was based on a methodology used by analysts at the World Resources Institute and ODI. There were some multilateral funds that could not be assigned using this methodology, which are therefore not captured in each country’s multilateral contribution.

Key developments
Gearing up
PRE-COP COMMITMENTS: China has “become the defender of international cooperation on climate change”, said state-sponsored newspaper Global Times the day before COP30 opened. China’s commitment to “dual carbon” goals will be the “driving force” of building a “beautiful China”, said an article by the Communist party-affiliated newspaper People’s Daily under the byline of Wang Huning, chairman of the Chinese People’s Political Consultative Conference.
WORLD’S EXPECTATIONS: China’s deputy permanent representative to the UN, Geng Shuang, said the country is “globally recognised as the [one] with the strongest determination, the most vigorous actions” on tackling climate issues, reported news agency Xinhua. John Kerry, former US climate envoy, told the Shanghai-based Paper: “The global climate agenda has undergone a fundamental shift, and calls are being made for China to continue playing a leading role in the event of a possible absence of the US.”

FINANCE PLEA: Meanwhile, Brazilian president Luiz Inacio Lula da Silva “urged” China’s vice premier Ding Xuexiang at a pre-COP30 meeting to “join financing initiatives for climate transition and resilience” and “help fund green technology and investment projects”, said the Hong Kong-based South China Morning Post (SCMP).
‘OUTPERFORM[ING]’ TARGETS: Most experts in a new survey expect China to “outperform” its 2035 emissions-reduction target, reported Bloomberg. About 71% of the surveyed experts believe China’s carbon-emission peak will “happen between 2026 and 2030, with most expecting it in 2028” – ahead of the official timeline of 2030, said Agence France-Presse.
Early moves
‘PROMISES KEPT’: China “keeps its promises and delivers on its commitments” on climate change, Ding said on 6 November, in remarks at COP30’s leaders summit, according to a transcript published by Communist party-affiliated newspaper the People’s Daily. Ding suggested that, to “advance” climate action, the world must “stay on the right track”, balancing “environmental protection, economic development, job creation and poverty eradication”. In addition, Ding said countries must “remove trade barriers” if the world is to meet its targets, said BBC News.
BUILDING COALITIONS: Over the weekend ahead of COP, Brazil, China and the UK co-led a summit on methane, launching initiatives that could “accelerate global action on methane and other non-CO2 greenhouse gases”, said a press release published on the COP30 website. These included “mobilising” at least $150m to support seven developing countries’ efforts, it added. China and the EU also agreed to join a Brazilian-led carbon-market coalition, Bloomberg reported, which “aims to develop common standards for monitoring, reporting and verification”.
TFFF FOREGONE: There are “still no guarantees” that China will contribute to Brazil’s Tropical Forest Forever Facility (TFFF), CNN Brasil said, contrary to reporting by Reuters in July that China might invest in the fund. The outlet added that Brazil may be able to push for Chinese participation again at the G20 meeting in late November. SCMP said “Chinese negotiators told their Brazilian counterparts that Beijing supported the fund in principle”, but cited the common but differentiated responsibilities concept as a reason not to commit.
OPENING STATEMENTS: In the face of an “intensifying” climate crisis, China “will not stop supporting” international action, Huang said at the opening of the China pavilion at COP30, attended by Carbon Brief. A number of representatives of major international organisations – including the UNFCCC’s Simon Stiell, the UN climate advisor Selwin Hart, UNEP executive director Inger Andersen – as well as Chinese climate envoy Liu Zhenmin all spoke at the event. Hart captured the mood, saying: “We are certain to count on the leadership of China over the course of the next two weeks, and also over the next decade.”
Trade spats
AGENDA FIGHT: The agenda for COP30 was “adopted on Monday as originally drafted without any amendments”, despite a request by a country group that includes China that the lineup include “provision of finance from rich countries and unilateral trade measures” such as the EU’s carbon border adjustment mechanism, Climate Home News reported. The topics are instead being discussed in presidency-led consultations, alongside calls from small-island states to push for greater emissions-cutting ambition and from the EU on emissions reporting. Carbon Brief’s Simon Evans set out the issues on Bluesky.
RIGHT HERE RIGHT NOW: The Like-Minded Developing Countries (LMDCs) group – of which China is a part – together with the Arab Group stated that unilateral trade measures “penalise developing countries and impact their ability to take action to address climate change”, reported Earth Negotiation Bulletin. They pushed back against arguments by Japan, the EU and others that discussions of unilateral trade measures would be “more appropriate under the World Trade Organization”, it added.
PRESIDENCY PAUSE: A “stocktaking plenary” on Wednesday ended abruptly with COP30 president André Corrêa do Lago announcing a further plenary on Saturday. Do Lago said that – despite “more than eight hours” of discussions – further consultations were still needed. Rumours are flying around how Brazil will manage this, with many expecting a COP30 decision responding to these thorny issues. It may be called a “cover decision” or be part of a “mutirão package”, a reference to an Indigenous word for collective efforts.
Cough up the cash
INDIA FOR BASIC: Meanwhile, according to a government press release, India has submitted a statement on behalf of the BASIC group, an institution initiated by China, as well as LMDCs, reaffirming that the “architecture of the Paris Agreement must not be altered, and that [common but differentiated responsibilities (CBDR)] remains the cornerstone of the global climate regime”. It added that “developed countries must…fulfil their obligations on finance, technology transfer and capacity-building to developing countries”, in particular by increasing adaptation finance flows by “nearly fifteen times” from current levels.
STATUS QUO: Chinese delegates have repeatedly emphasised China’s status as a developing country and the need for CBDR in early statements at COP. Writing in the Backchannel substack, Asia Society Policy Institute China climate hub and climate diplomacy director Kate Logan and E3G senior policy advisor Lily Hartzell wrote that China’s “high-level delegations have cautiously avoided any wording that might suggest a bid for formal climate leadership, particularly when it comes to climate finance”.
LEADING COMMENT: In his speech at the leaders’ summit, Ding stated that “developed countries should fulfill their obligations to take the lead in reducing emissions, honour their financial commitments and provide developing countries with more technical and capacity-building support”. This contrasts his address at COP29, where Ding highlighted China’s role in “provid[ing] and mobilis[ing]” climate finance – sparking much speculation that the country may soon change its approach to the topic.
COME BACK TO US: Li Gao, the head of China’s delegation at COP30, told Agence France-Presse that China “welcome[d]” the “Baku to Belém roadmap” towards the aspirational target of $1.3tn in climate finance by 2035 from all sources, but that it is “crucial” for the developed countries to fulfil their $300bn commitment made at COP29. Li added that “we hope that some day, and we also believe that some day in the future, the US will come back”, because “addressing climate change needs every country”.
Global south solidarity
KEY THEME: China is working towards “jointly creating a green future” for the global south, Huang said in a session on south-south development held on the first day of COP30, attended by Carbon Brief. He added: “We pay attention to the needs of developing countries.” President of the Belt and Road International Green Development Coalition (BRIGC) Zhao Yingmin said on a separate event at the China pavilion that “construction of the [Belt and Road Initiative (BRI)] is also an important driver for developing countries to advance their green transitions”. A number of initiatives were publicised during the first few days of COP, including an agreement between China, Malawi and Kenya on clean cooking and a project to collate “global case studies on green development” by BRIGC.
BUILDING CAPACITY: The BRIGC programme is “exactly the type of example we want [to see at] the COP – implementation, implementation, implementation”, said COP30 CEO Ana Toni, speaking at the launch event attended by Carbon Brief. Selwin Hart, special adviser to the secretary-general on climate action and just transition at the United Nations, emphasised at a China pavilion event that Brazil and China showed “leadership” in climate action, noting that “you [emerging economies] understand us better” than developed countries – referencing an understanding of the need for capacity building in global south countries.
‘FRANK REMARKS’: Meanwhile, an opinion article in the state-supporting Global Times, bylined simply as “Global Times”, quoted COP30 president André Corrêa do Lago saying “You can’t insist that China has to lower its emissions [and then] complain that China is putting cheap [electric vehicles] all over the world”. It added that these “frank remarks should serve as a wake-up call” against “politicising China’s green efforts”.
STRONG INTEREST: The two events on south-south cooperation, both attended by Carbon Brief, appeared to be the best-attended China pavilion events so far. One audience member, a Brazilian chemical engineer, told Carbon Brief that she was attending the session because she was interested in understanding China’s experience of navigating the energy transition as a developing country.
Views on the energy transition
‘CONCRETE PROGRESS’: “We have made concrete progress in energy transformation”, Li said at the China pavilion, adding it involved a “very hard effort”. Climate envoy Liu noted at the same event that “China, as a major country, reaffirms its confidence in achieving the [Paris Agreement] goals”. He said that China “sees the next 10 years as a critical period for delivering on the commitments made under the Paris Agreement”, adding: “We look forward to all countries delivering their contributions on this goal.”
FOSSIL PHASE-OUT?: In his opening speech at the leaders’ summit, Brazil’s Lula called on world leaders to draw roadmaps to “overcome dependence on fossil fuels”, adding that he was “convinced” that this could be done “despite [countries’] difficulties and contradictions”, Argus Media reported. In the opening session of the China pavilion, attended by Carbon Brief, UNEP’s Andersen said she “encourage[d] China to take even bolder action…[and] explore setting targets on coal”.
PRIORITIES FOR 2030: Lyu Wenbin, director general of China’s Energy Research Institute, stated that a key task in the next five years included “improving the quality of energy supply”, including “boosting non-fossil energy” while “shifting coal power to a supporting role” in the energy mix. He added that in the medium- to long-term, China will build an energy system that has “non-fossil energy as the main supply [of power] and fossil energy as a guarantee [of energy security]”.
FLAT OR FALLING: Meanwhile, analysis for Carbon Brief found that China’s carbon dioxide emissions were “unchanged from a year earlier in the third quarter of 2025, extending a flat or falling trend that started in March 2024”. The analysis has been covered widely in publications including China’s Global Times, the New York Times, Financial Times, Reuters, Bloomberg and on the frontpage of the Guardian.
Captured
Bai Quan, director of the Energy Research Institute of the Academy of Macroeconomic Research – a research institution managed by the National Development and Reform Commission – outlined how China’s energy landscape might evolve between 2024 and 2060, during the launch of the China Energy Transformation Outlook (CETO) 2025 at the China Pavilion, attended by Carbon Brief.

The number of delegates China has sent to Belém, according to analysis by Carbon Brief. This includes more than 100 party delegates and almost 700 “overflow” delegates, including from local government, the private sector, non-government organisations and foreign consulting firms.
New science
Scientific Reports
“Environmental penalties indirectly influence climate-friendly technological innovation through their effects on the digital economy and financial technology”, according to a new study. The paper used data from Chinese cities to model this influence. The authors found that environmental penalties have a “U-shaped” effect, noting a “critical inflection point where environmental penalties shift from promoting to inhibiting these innovations”.
Scientific Reports
New research investigated the “carbon rebound effect”, defined in the paper as “the phenomenon in which, after energy efficiency improvements, carbon emissions rebound due to increased economic activity, thus undermining the reduction in emissions achieved through efficiency gains”. Using machine-learning methods, the authors assessed data from Chinese cities collected over 2010-21. According to the paper, the effect is stronger in the north of China than the south and in the east than the west.
