As nations assemble at COP29 in Baku, Azerbaijan, one issue is expected to dominate the summit: climate finance.
In total, countries need to invest trillions of dollars to build clean-energy systems, prepare for an increasingly hotter world and deal with the aftermath of climate change-fuelled disasters.
The UN climate convention also specifically requires developed nations to provide financial resources – usually referred to as “climate finance” – to help developing countries do this.
Under the Paris Agreement, governments agreed to set a new climate finance target by 2025 that would channel money into these nations and help them tackle climate change.
But negotiations over this “new collective quantified goal” (NCQG) for climate finance in recent months have exposed deep divides in the UN climate process.
Nations disagree on virtually every element of the NCQG, including the amount of money that needs to be raised, who should contribute, what types of finance should feed into it, what it should fund and what period of time it should cover.
Developing countries are looking to high-income parties, such as the US and the EU, to provide the money. Meanwhile, developed countries want an all-encompassing goal that includes input from private companies and large, emerging economies, such as China.
In this article, Carbon Brief explores the issues countries have been clashing over, which will have to be resolved to secure an outcome in Baku.

- What kind of activities will the NCQG support?
- How long will countries have to meet the NCQG?

Why are countries discussing a new climate finance goal?
Climate finance is at the heart of international climate politics. It is widely understood that developing countries need to invest large sums of money if they are to cut their emissions and prepare for a hotter world, in line with their climate plans.
The nature of climate finance is disputed, but, currently, it largely comes from developed countries’ aid budgets and contributions from multilateral funds and development banks (MDBs), such as the World Bank. Smaller amounts come from the private sector.
When nations negotiated the UN Framework Convention on Climate Change (UNFCCC) in 1992, the treaty said that developed countries “shall provide” financial resources to help developing countries tackle climate change.
In 2009, developed countries agreed to “mobilise” $100bn of climate finance a year by 2020 – an annual target that was meant to run through to 2025. This became a fraught topic, as developed nations missed the 2020 deadline and only reached it two years later in 2022.
In the Paris Agreement of 2015, Article 9 reaffirms that “developed country parties shall provide financial resources to assist developing country parties”. Nations also decided that, before 2025, they:
“Shall set a new collective quantified goal from a floor of $100bn per year, taking into account the needs and priorities of developing countries.”
This “new collective quantified goal” (NCQG) is the focus of negotiations at COP29. With the 2025 deadline approaching, this will be the final opportunity to settle on the new target.
Negotiators have been gathering for months to discuss the issue, in an effort to find a landing ground. However, the NCQG is both very technical and highly politicised, leaving them deadlocked on most issues.
Following several rounds of negotiations, the co-chairs (from Australia and the United Arab Emirates) overseeing the talks were tasked with producing a “substantive framework for a draft negotiating text”, which would form the basis of COP29 deliberations.
The resulting document offers the outlines of the new climate finance target and crystallises the key areas of remaining disagreement. It is nine pages long and contains 173 elements that are still in square brackets, meaning they are undecided.
What number will replace $100bn in the new target?
Unlike the $100bn, which was an arbitrary number put forward by global-north leaders, the NCQG must take into account the “needs and priorities of developing countries”. Many assessments have shown that these nations’ investment needs will run to trillions of dollars for tackling climate change in the coming years.
However, setting a numerical climate finance target – or “quantum” – is not straightforward. Many of the future demands of dealing with climate change are difficult to quantify and there has been no officially mandated effort to work out what these needs are under the NCQG.
The closest attempt is the “needs determination report” from the UN Standing Committee on Finance, based on combining various reports in which developing countries have self-assessed their own requirements. However, the committee stresses that its estimate of $5-6.9tn over the next five years contains “significant gaps” and, therefore, is not a true reflection of needs.
An analysis by the Overseas Development Institute (ODI) points out that this leaves NCQG negotiators relying on various calculations by NGOs, management consultancies and research groups “undertaken under different contexts, for possibly different objectives and with different mandates”.
Despite this lack of clarity, negotiators have converged around the need for trillions of dollars to deal with climate change. But arriving at a more precise figure for the NCQG has proved difficult, in part because countries do not agree on what it is supposed to include.
Developing countries prefer a target made up largely of public funds from developed countries. Meanwhile, developed countries have proposed targets covering a much larger range of sources and including “global investment flows”, rather than public money given by developed countries to developing ones alone. (See: What sources of money should be included in the NCQG?)
As a result, Iskander Erzini Vernoit, director of the Imal Initiative for Climate and Development, tells Carbon Brief that, “while all parties are talking about trillions, they are doing so in entirely different ways”.
Developing country groups, including the Like-Minded Developing Countries, the Arab Group and the African Group, have proposed a few ideas for climate finance targets, all in the region of $1-1.3tn a year, as the chart below shows. Pakistan has proposed the highest figure so far – “a minimum of $2tn” – but it has not specified the timeframe.
Meeting such a target would require an unprecedented tenfold boost in climate finance by 2025. (However, it is difficult to compare like-for-like, as countries have different expectations about the sources that will make up the NCQG target.)

After years of developed countries struggling to hit the relatively modest $100bn goal, these new demands raise the issue of plausibility.
Major contributors including the UK, France and Sweden have all slashed their aid budgets in recent years, reducing the pool of public finance available.
Meanwhile, the US has consistently underperformed in providing climate finance. This is despite most analyses indicating that it should be by far the largest contributor, as it is the world’s richest country and the biggest historic contributor to climate change.
Jonathan Beynon, a senior policy associate at the Center for Global Development, tells Carbon Brief:
“Public budgets are under pressure in most developed countries, prospects for such massive increases in climate finance look limited, however justified they might seem.”
Developed countries stress the need for a “realistic” NCQG target. In one statement, the US mentions the annual needs of developing countries exceeding $1tn a year, but says “it is clear that public international finance alone cannot reach such levels”. It adds:
“There is a fine line between a support goal that stretches contributing parties and one that is so unrealistic that it actually diminishes incentives and potentially undermines the Paris Agreement process.”
Furthermore, the US argues that developed countries do not have to meet the “totality of needs” in developing countries, noting that the NCQG mandate only requires parties to “tak[e] into account” these needs.
Developed countries have largely resisted suggesting a numerical target for the NCQG. They argue that a specific amount cannot be agreed upon until a decision is made on who will contribute towards it. The US has only gone so far as to restate that the goal should be “from a floor of” $100bn per year – as already set out by the Paris text.
(Experts have noted that the $100bn goal should be corrected for inflation, at the very least, which would add many billions of dollars. Beynon says “inflation and economic growth alone” would allow “perhaps a doubling by 2035”.)
Another developed-country proposal from the EU mentions a goal of $2.4tn annually by 2030, a number identified by the Independent High-Level Expert Group on Climate Finance – a group of economists tasked with working out the “investment” needs in developing countries.
In the expert group’s proposal, just $150-200bn per year would come directly from other countries, with $1.4tn from the domestic resources of developing countries themselves.
Alex Scott, a senior associate in climate diplomacy at the thinktank ECCO, noted in a recent briefing that progress outside negotiations, such as mobilising more climate finance from the World Bank, could “build a bit more confidence amongst developed countries that…there are other sources of finance that are going to complement what they can put on the table”.
One recent assessment by a team of NGO climate-finance analysts concluded that a “business-as-usual” scenario could result in $173bn of climate finance being provided and mobilised by 2030 – a 50% increase from 2022 levels. This is based on existing pledges by developed countries and planned reforms to multilateral institutions.
Others in civil society point to the trillions spent on Covid-19 and the war in Ukraine, and the trillions that could be raised by taxing fossil fuels and billionaires. Meena Raman, head of programmes at the Third World Network, tells Carbon Brief that the unwillingness of developed countries to commit to more funding is a failure of “political will”:
“It’s very dubious when you say you have not got enough money for climate, but you see that there is a lot of money for bombs and wars.”
Which countries will contribute to the new target?
One of the most contested topics in NCQG negotiations is whether to expand the list of countries that must provide climate finance.
Global-north nations broadly want relatively wealthy, emerging economies, such as China and the Gulf states, to start contributing officially under the UN climate regime. Developing countries argue that, after failing to meet their climate-finance targets, developed countries are trying to shift their responsibilities.
As it stands, only 23 countries are obliged to provide climate finance, including western Europe, the US, Japan, Australia, Canada and New Zealand. The EU must also provide climate finance, independently from the funds provided by its member states.
This group, listed in “Annex II” of the UNFCCC, is based on the membership of the Organisation for Economic Co-operation and Development (OECD) in 1992. (OECD member Turkey secured removal from Annex II in 2001, on the basis that it was an emerging economy.)
The world has changed a lot in the three decades since the contributor list was agreed.
As the chart below shows, emissions from non-Annex II countries, particularly China, have increased significantly since 1992. Many of these nations are also wealthier, and both of these factors are frequently cited as reasons for such countries to start paying climate finance.

There have been consistent efforts by donor countries to broaden the pool of climate finance providers. Indeed, the language in the Paris Agreement reflects this, saying that “other parties” are “encouraged to provide” climate finance “voluntarily”.
However, the division between countries “obliged” versus “encouraged” to contribute has remained. Only Annex II countries were responsible for delivering the $100bn goal.
Developed countries are clear that bringing more donors on board for the NCQG is a priority for them. In a submission ahead of negotiations, the EU refers to “evolving” responsibilities and abilities to pay. It states that:
“The collective goal can only be reached if parties with high greenhouse gas emissions and economic capabilities join the effort.”
The US says that, in its view, agreeing to renegotiate the climate-finance target from 2025 was done on the basis of considering new contributors, making this topic “entirely legitimate, indeed appropriate”.
Developing countries, on the other hand, are firmly opposed to any changes. They argue that it is beyond the legal mandate of the NCQG.
The G77 and China group of 134 developing countries stresses that the NCQG falls under the Paris Agreements and the UNFCCC. Therefore, it includes the principle of “common but differentiated responsibilities and respective capabilities” (CBDR-RC).
In this case, CBDR-RC refers to developed countries’ obligation and capacity to provide climate finance to developing countries. This principle is “not negotiable” and the NCQG mandate “does not include any discussions on modifications” to climate treaties, the G77 and China group says.
There is no agreed-upon way to determine how responsible countries are for causing climate change, and how much they should be helping to prevent it. This makes determining who could or should contribute to an expanded donor base complicated.
The table below, which draws on a recent paper led by Dr Pieter Pauw of Eindhoven University of Technology, shows various metrics that have been considered to identify new donors for the NCQG.
These include how countries are identified under various international treaties, measures of emissions and wealth, membership of powerful institutions and willingness to contribute to global development funds.
There are 50 non-contributor countries that tick two or more of these boxes, with a handful of relatively wealthy or large nations scoring the highest. (As with any attempt to identify new contributors, this ranking relies on subjective criteria. It scores all of these factors equally without making a judgement of how important they are, and countries are ranked in the order they appear in the study).
Non-contributor countries that meet a selection of potential criteria for contributing to the NCQG. Criteria include how countries are defined under various international treaties, including the UNFCCC, the Montreal Protocol and the Convention on Biological Diversity. Other criteria include different measures of higher CO2 emissions or gross national income (GNI) than the median Annex II country; membership of powerful institutions (EU, OECD, G20); and “significant” (greater than $5m) contributions to global climate, environment and development funds. Source: Adapted from Pauw et al. (2024).
Most proposals for identifying new contributors consider a country’s ability to pay – measured using gross national income (GNI) – and its responsibility for climate change, often based on historical emissions. Nations such as Canada and Switzerland have proposed a new system for determining climate-finance donors, based on this kind of data.
Yet different versions and combinations of these metrics can yield very different results. Focusing on total emissions and economic status generally throws up a selection of large, emerging economies, including China, India, Russia and Brazil.
However, many analyses include some variation of per-capita emissions and income, to ensure a “fairer” representation that does not penalise countries with large populations.
Such calculations suggest that small, wealthy fossil-fuel producers, including the United Arab Emirates, Qatar and Kuwait, and small, high-income nations, such as Israel, South Korea and Singapore, should contribute to climate finance.
But outcomes can vary significantly, even when accounting for per-capita measures. The best example of this is China, which is the consistent focus of developed-country efforts to expand the contributor list.
Some assessments identify China as an obvious candidate for future contributions – and one that could make a big difference to total spending. Analysis by the Centre for Global Development (CGD) suggests, based on methods that take per-capita metrics into account alongside other factors such as aggregate GNI, that China should contribute up to around 7% of climate finance.
However, if comparability with Annex II countries is considered important when measuring per-capita historical emissions and income, as in analysis by the thinktank ODI, the results are very different. China still ranks far below any of the current developed countries that provide climate finance on these measures.
In fact, the charts below, based on WRI figures, show that major climate finance contributors still largely surpass emerging economies on both per-capita historical emissions from fossil fuels and industry, and per-capita GNI. (These rankings remain roughly the same if land-use emissions are included, although Russia rises higher in the list.)

Given this, the ODI concludes in its analysis that demands for China to become a contributor have “dubious” scientific basis and are “based on geopolitics, particularly China’s status as global power and international financier”.
All of this is further complicated by the fact that many relatively wealthy countries that are not obliged to provide climate finance, including China and South Korea, already contribute climate-related aid and other funding that could be classified as climate finance.
Yet there is resistance from nations such as China to formally classifying their activities as “climate finance” under the UN. Doing so could result in them facing more scrutiny and accountability.
It could also have great political significance given the long-standing division between “developed” and “developing” states in UN talks. This “firewall” was partially broken down with the Paris Agreement, which compelled all countries to set their own “nationally determined contribution” to climate action, but has remained in place for climate finance.
Charlene Watson, a senior research associate at the ODI, says developed country officials argue that having more countries on board makes it easier for them to persuade their treasuries to release more climate finance. However, she questions the value of insisting countries that already provide climate-related funds are included in the UN system:
“My view is that the cake is not going to get any bigger in the short term. It’s just going to be that we can better see the size of the cake.”
Pauw says there is a need for more nuance, including a new category of “net recipients” that both give and receive climate finance. He says coming up with a new list of contributors may be too difficult:
“Whatever you push forward as an idea is arbitrary. There will always be countries who say ‘we cannot agree to this’ – which means that you will not reach agreement.”
One compromise that has been proposed is to introduce different contributor bases for different “layers” of the NCQG, if countries agree on a “multilayered” goal.
That way, China and others might not be responsible for contributing to the “new $100bn” part of the goal, but may be covered by another layer. (See: What sources of money should be included in the NCQG?)
Meanwhile, Vernoit says poorer developing countries are “extremely wary” of the contributor base discussions, as any ambiguity over who is obliged to provide climate finance could hamper its provision. “Accountability is why burden-sharing frameworks and differentiated lists, like the Annex II list, are important to poorer recipient countries,” he explains.
What sources of money should be included in the NCQG?
Another highly contentious issue in the NCQG negotiations is what types of finance should feed into it. This inevitably influences the discussion of how big the goal could be.
The $100bn target is already fairly broad, covering finance “from a wide variety of sources, public and private, bilateral and multilateral, including alternative sources of finance”.
This in itself is controversial, with civil society groups and developing countries often arguing that the goal relies too much on low-quality finance, such as non-concessional loans. Nevertheless, the NCQG has the potential to be even broader.
Developed countries argue that expanding the scope, with a focus on private investment and gearing the entire financial system towards climate action, is the only way to raise the trillions of dollars of money required.
These wealthier nations generally want the goal to be “multilayered”, with a large outer layer consisting of “global investment flows for climate action”. The framing is important, as it could refer to all kinds of money being spent everywhere – not only in developing countries – including investments made by the developing countries themselves.
The developed nations also propose a smaller sub-goal within this investment layer, more aligned with traditional “climate finance”, which consists of finance “provided” and “mobilised” for developing countries.
(Here, “provided” is understood as referring to climate finance given by one country to another, while “mobilised” refers to private investment that comes as a result of public money “de-risking” investments and getting projects off the ground.)
This approach could make a big difference to how much money these countries would be obliged to provide. For example, an EU submission describes an “investment” goal in the trillions, in contrast to a “provided and mobilised” goal in the billions.
In addition, developed-country statements have stressed the “important role of the private sector”, the need for “reforming the multilateral financial architecture to further unlock climate finance” and the role of “innovative financial instruments” to raise more money.
By contrast, many developing countries have argued for a single goal that channels high-quality climate finance from developed countries to them in a reliable way.
In practice, this means developing countries want as much of it as possible to come in the form of grants from developed countries’ public coffers. The Arab Group has suggested that at least $441bn of the $1.1tn in annual climate finance it has proposed should come from developed-country grants.
All of this speaks to a central tension about the significance of two articles in the Paris Agreement. Article 9 states that developed countries are obliged to provide climate finance to developing countries and others are encouraged to do so voluntarily. Article 2.1c, meanwhile, calls for all “financial flows” to be aligned with the agreement’s goals.
As the WRI diagram below shows, developing countries want to keep the NCQG talks focused on Article 9, whereas developed countries say both articles should be covered. Developed countries, such as Japan, have said that they think Article 2.1c also justifies expanding the contributor base. (See: Which countries will contribute to the new target?)

Pauw of Eindhoven University of Technology tells Carbon Brief that this comes down to a fundamental difference of opinion on what climate finance is and should be.
On the one hand, the world needs to channel as much money as possible into tackling climate change and, on the other hand, there is the question of transferring money from developed to developing countries – often framed using the language of climate justice. He says:
“You can’t mobilise a lot of money if you provide everything in grants. So those two motivations seem to clash, and it’s important to understand that both of them are relevant, both of them are important and both of them need to be realised.”
The wording below from the proposed “draft negotiating text” released ahead of the COP29 negotiations shows the main options on the table for the NCQG.
Option 1 broadly captures ideas proposed by developing countries, while option 2 captures the layered “annual investment goal” presented by developed countries.

There are practical reasons for developing countries wanting to avoid certain types of finance in the NCQG.
Some global-north leaders have framed private finance as essential for meeting the needs of developing countries. For example, when asked about climate finance, former US climate envoy John Kerry repeatedly stated that “we don’t have the money”, arguing that the key would be to encourage more private capital into climate-related activities.
Yet the amount of private climate finance “mobilised” by developed countries remained virtually unchanged at around $14bn each year between 2016-2021, only increasing significantly to $22bn in 2022. (This is based on OECD data for private finance with a clear causal link to a donor country sending development finance to a project.)
Private investment is also far less likely to flow into the poorest countries, many of which are the most in need of climate finance. It is often viewed as unsuitable for many climate-adaptation projects, which are less likely to generate profits than mitigation work such as clean-energy projects.
Moreover, while national governments are within the remit of the UNFCCC and the Paris Agreement, private companies and other financial actors, such as banks, are not. This could make it more risky to rely on them to meet the NCQG.
There are also strong calls from many developing countries to exclude “non-concessional” loans – provided at or near market rates – from climate finance altogether.
Since 2016, around 70% of public climate finance has been delivered in the form of loans, with Japan, France and Germany, as well as MDBs, providing most of their contributions in this way.
UN figures suggest that at least one-fifth of reported loans are “non-concessional”, resulting in wealth flowing back to the donor countries as loan repayments and interest, according to a Reuters investigation.
Many of the poorest countries are spending more on servicing debts than they receive in climate finance, according to the International Institute for Sustainable Development.
These debates form part of a wider discussion around the “quality” of finance.
Developing countries want finance to be predictable and accessible, especially given the complications they often face when obtaining it from MDBs and large funds.
For their part, developed countries are more likely to emphasise the need for “effective” climate finance – meaning funds that are used for their intended purposes and have a climate impact.
What kind of activities will the NCQG support?
Finance for climate action is divided into broad categories, depending on its main purpose. The $100bn target supports two types of activities: those that cut emissions – mitigation; or those that help countries adapt to climate change.
Now, there is pressure from most developing countries to include loss and damage as a “third pillar” in the NCQG. This would enshrine support for the victims of climate disasters as an official component of the international climate finance goal, for the first time.
After years of fraught negotiations, developing countries secured a “win” last year with the launch of the loss-and-damage fund at COP28.
However, contributions to the fund have been small compared to the scale of climate-related damages, which are estimated to reach $447bn-894bn per year by 2030.
Some developing countries would like to see NCQG sub-goals in order to ensure there is ring-fenced funding available for adaptation – which remains poorly resourced compared to mitigation – and for loss and damage. This would involve percentages of the overall target being assigned to each of the three pillars.
Sherri Ombuya, a consultant at Perspectives Climate Group, tells Carbon Brief that there has been some convergence between parties on the general idea of increasing adaptation finance. “This builds on some existing positions that have already taken place within the broader negotiation space,” she says.
(Developed country parties have already pledged to double adaptation finance from 2019 levels by 2025, for example.)

However, developed countries broadly do not want to incorporate loss and damage under the NCQG. They argue that, while a fund for loss and damage finance has now been established, contributions to it are voluntary and not part of the NCQG mandate.
Moreover, Article 9 of the Paris Agreement only refers to climate finance for “mitigation and adaptation” – and the Paris “decision text” that mandates the NCQG does the same.
Developing countries argue that including loss and damage in the NCQG is nevertheless valid, because Article 8 of the Paris Agreement separately “recognises” the importance of “averting, minimising and addressing” loss and damage.
They also see room for the climate-finance goal to expand over time, to reflect the changing needs of developing countries, in line with the Paris Agreement requirement that “efforts of all parties will represent a progression over time”.
How long will countries have to meet the NCQG?
Parties at COP29 must also agree on the timeframe for the provision of climate finance under the NCQG, as this was not specified in Paris.
A key source of conflict concerns whether the target should cover a shorter period of around five years or a longer one of 10 years or more.
Some developing party groupings, including the LMDCs and the Arab Group, have expressed a preference for a five-year goal covering the period from 2025-2030, with the same amount of money – roughly $1tn – provided every year.
An advantage of having a shorter timeframe could be that it gets money moving faster. Supporters also stress the importance of a “revision” or “review” process once the five years are up, in order to adequately reflect “the evolving needs of developing countries”.
Other developing countries, including AOSIS and the Least Developed Countries (LDCs), have supported a 10-year timeframe, but with some kind of review after around five years.
Some parties and civil-society groups have pointed out that a five-year timeframe aligns with existing processes for monitoring progress under the Paris Agreement.
Both the global stocktake and national climate plans – known as “nationally determined contributions” (NDCs) – run on five-year cycles and could, therefore, feed into a review of the NCQG goal.
In an assessment of the NCQG, the World Resources Institute (WRI) notes that, while there are advantages to revisiting the target, “reopening negotiations on the NCQG during revision cycles has the potential to cause additional delays and complexity”.
Meanwhile, developed countries including Switzerland and the EU favour a 10-year timeline.
Notably, they have suggested that the NCQG will be achieved “by 2035”. This leaves room to gradually scale funding up over time rather than achieving it up from 2025 onwards, meaning less immediate pressure on contributors.
How will progress towards the target be reported and tracked?
There is general agreement that a workable NCQG requires a system where governments and other institutions report their climate finance transparently. Only then can progress towards the goal be tracked – and contributors held accountable.
As it stands, there are fundamental gaps in the system for tracking climate finance.
Despite being agreed upon in 2009, there was no official UN system in place to track progress towards the $100bn goal until the Standing Committee on Finance (SCF) was tasked with doing so in 2021 – one year after the goal was supposed to have been delivered.
This does not mean that no one has been reporting climate finance. Developed countries have to produce reports for the UNFCCC every two years, which must include the finance they have channelled into developing countries, both directly and through multilateral institutions.
Developed countries also submit information about climate-related spending to the OECD, which publishes its own assessments of climate-finance progress. (In addition, the OECD served as the de facto tracker of progress towards the $100bn goal.)
Meanwhile, NGOs – particularly Oxfam – have produced regular analyses of climate finance.
Crucially, these assessments arrive at very different estimates of how much climate finance has been provided to developing countries. This is partly because there is no widely accepted definition of “climate finance” in the UN climate process.
Nations are allowed to come up with their own definitions of what counts, as well as their own methodologies to track, measure and report it to official bodies. “This results in challenges in aggregating data on climate finance,” according to the SCF.
The lack of clarity around climate-finance figures has contributed to a “continuous erosion of trust between parties in international climate negotiations”, according to one paper.
Real-world implications include governments inflating the amounts they have given and labelling questionable funding for everything from coal to hotels as climate finance.
So far in the NCQG discussions, there has been a broad consensus that the enhanced transparency framework (ETF) is the best way to report on progress. The ETF is a system set up under the Paris Agreement, which requires most parties to submit information about their climate progress in biennial transparency reports (BTR) from the end of this year.
However, the ODI’s Watson tells Carbon Brief that even if this is agreed there will still be plenty to discuss in the NCQG transparency negotiations:
“The ETF just captures reporting from countries…The more we start talking about whether other sources [of finance] count, or how to capture finance from purely private actors, they’re obviously not covered by the BTRs that come out of the ETF. So what else do we need to know?”
These discussions are, therefore, tied to the question of which sources feed into the NCQG and also which countries contribute towards the goal.
Developing countries have fewer reporting obligations under the ETF and there may be pressure on them to report more if the contributor base is expanded, Watson says.
As for tracking the resulting figures, some parties have suggested the SCF should be given this task. Governments may prefer to opt for a UN committee rather than leaving the task to an NGO or external international body, but this may still face opposition.
Finally, despite the apparent convergence between parties on some of the transparency requirements, there is far less agreement on the need to define “climate finance”.
The G77 and China group of developing countries has pushed for such a definition, calling for non-concessional loans and “non-climate specific finance” to be excluded.
Many developing countries stress that climate finance must be defined as “new and additional”, in line with the language used when the $100bn target was set and in the original UNFCCC treaty. This is broadly understood to mean money that comes on top of other obligations.
However, developed countries provide much of their climate finance from their aid budgets and studies suggest that much of this is not “new and additional”.
Given the impact it could have on their finances, developed countries have strongly resisted a strict definition. Perspectives Climate Group’s Ombuya tells Carbon Brief that, while she thinks it is possible that parties could converge on excluding some types of finance from the NCQG, “I feel that to have a successful outcome, it’s likely that parties will have to have a willingness to do without a common definition on climate finance”.

The 2026 budget test: Will Australia break free from fossil fuels?
In 2026, the dangers of fossil fuel dependence have been laid bare like never before. The illegal invasion of Iran has brought pain and destruction to millions across the Middle East and triggered a global energy crisis impacting us all. Communities in the Pacific have been hit especially hard by rising fuel prices, and Australians have seen their cost-of-living woes deepen.
Such moments of crisis and upheaval can lead to positive transformation. But only when leaders act with courage and foresight.
There is no clearer statement of a government’s plans and priorities for the nation than its budget — how it plans to raise money, and what services, communities, and industries it will invest in.
As we count down the days to the 2026-27 Federal Budget, will the Albanese Government deliver a budget for our times? One that starts breaking the shackles of fossil fuels, accelerates the shift to clean energy, protects nature, and sees us work together with other countries towards a safer future for all? Or one that doubles down on coal and gas, locks in more climate chaos, and keeps us beholden to the whims of tyrants and billionaires.
Here’s what we think the moment demands, and what we’ll be looking out for when Treasurer Jim Chalmers steps up to the dispatch box on 12 May.
1. Stop fuelling the fire
2. Make big polluters pay
3. Support everyone to be part of the solution
4. Build the industries of the future
5. Build community resilience
6. Be a better neighbour
7. Protect nature
1. Stop fuelling the fire

In mid-April, Pacific governments and civil society met to redouble their efforts towards a Fossil Fuel Free Pacific. Moving beyond coal, oil and gas is fundamental to limiting warming to 1.5°C — a survival line for vulnerable communities and ecosystems. And as our Head of Pacific, Shiva Gounden, explained, it is “also a path of liberation that frees us from expensive, extractive and polluting fossil fuel imports and uplifts our communities”.
Pacific countries are at the forefront of growing global momentum towards a just transition away from fossil fuels, and it is way past time for Australia to get with the program. It is no longer a question of whether fossil fuel extraction will end, but whether that end will be appropriately managed and see communities supported through the transition, or whether it will be chaotic and disruptive.
So will this budget support the transition away from fossil fuels, or will it continue to prop up coal and gas?
When it comes to sensible moves the government can make right now, one stands out as a genuine low hanging fruit. Mining companies get a full rebate of the excise (or tax) that the rest of us pay on diesel fuel. This lowers their operating costs and acts as a large, ongoing subsidy on fossil fuel production — to the tune of $11 billion a year!
Greenpeace has long called for coal and gas companies to be removed from this outdated scheme, and for the billions in savings to be used to support the clean energy transition and to assist communities with adapting to the impacts of climate change. Will we see the government finally make this long overdue change, or will it once again cave to the fossil fuel lobby?
2. Make big polluters pay

While our communities continue to suffer the escalating costs of climate-fuelled disasters, our Government continues to support a massive expansion of Australia’s export gas industry. Gas is a dangerous fossil fuel, with every tonne of Australian gas adding to the global heating that endangers us all.
Moreover, companies like Santos and Woodside pay very little tax for the privilege of digging up and selling Australians’ natural endowment of fossil gas. Remarkably, the Government currently raises more tax from beer than from the Petroleum Resource Rent Tax (PRRT) — the main tax on gas profits.
Momentum has been building to replace or supplement the PRRT with a 25% tax on gas exports. This could raise up to $17 billion a year — funds that, like savings from removing the diesel tax rebate for coal and gas companies, could be spent on supporting the clean energy transition and assisting communities with adapting to worsening fires, floods, heatwaves and other impacts of climate change.
As politicians arrive in Canberra for budget week, they will be confronted by billboards calling for a fair tax on gas exports. The push now has the support of dozens of organisations and a growing number of politicians. Let’s hope the Treasurer seizes this rare window for reform.
3. Support everyone to be part of the solution
As the price of petrol and diesel rises, electric vehicles (EVs) are helping people cut fuel use and save money. However, while EV sales have jumped since the invasion of Iran sent fuel prices rising, they still only make up a fraction of total new car sales. This budget should help more Australians switch to electric vehicles and, even more importantly, enable more Australians to get around by bike, on foot, and on public transport. This means maintaining the EV discount, investing in public and active transport, and removing tax breaks for fuel-hungry utes and vans.
Millions of Australians already enjoy the cost-saving benefits of rooftop solar, batteries, and getting off gas. This budget should enable more households, and in particular those on lower incomes, to access these benefits. This means maintaining the Cheaper Home Batteries Program, and building on the Household Energy Upgrades Fund.
4. Build the industries of the future

If we’re to transition away from fossil fuels, we need to be building the clean industries of the future.
No state is more pivotal to Australia’s energy and industrial transformation than Western Australia. The state has unrivaled potential for renewable energy development and for replacing fossil fuel exports with clean exports like green iron. Such industries offer Western Australia the promise of a vibrant economic future, and for Australia to play an outsized positive role in the world’s efforts to reduce emissions.
However, realising this potential will require focussed support from the Federal Government. Among other measures, Greenpeace has recommended establishing the Australasian Green Iron Corporation as a joint venture between the Australian and Western Australian governments, a key trading partner, a major iron ore miner and steel makers. This would unite these central players around the complex task of building a large-scale green iron industry, and unleash Western Australia’s potential as a green industrial powerhouse.
5. Build community resilience
Believe it or not, our Government continues to spend far more on subsidising fossil fuel production — and on clearing up after climate-fuelled disasters — than it does on helping communities and industries reduce disaster costs through practical, proven methods for building their resilience.
Last year, the Government estimated that the cost of recovery from disasters like the devastating 2022 east coast floods on 2019-20 fires will rise to $13.5 billion. For contrast, the Government’s Disaster Ready Fund – the main national source of funding for disaster resilience – invests just $200 million a year in grants to support disaster preparedness and resilience building. This is despite the Government’s own National Emergency Management Agency (NEMA) estimating that for every dollar spent on disaster risk reduction, there is a $9.60 return on investment.
By redirecting funds currently spent on subsidising fossil fuel production, the Government can both stop incentivising climate destruction in the first place, and ensure that Australian communities and industries are better protected from worsening climate extremes.
No communities have more to lose from climate damage, or carry more knowledge of practical solutions, than Aboriginal and Torres Strait Islander peoples. The budget should include a dedicated First Nations climate adaptation fund, ensuring First Nations communities can develop solutions on their own terms, and access the support they need with adapting to extreme heat, coastal erosion and other escalating challenges.
6. Be a better neighbour
The global response to climate change depends on the adequate flow of support from developed economies like Australia to lower income nations with shifting to clean energy, adapting to the impacts of climate change, and addressing loss and damage.
Such support is vital to building trust and cooperation, reducing global emissions, and supporting regional and global security by enabling countries to transition away from fossil fuels and build greater resilience.
Despite its central leadership role in this year’s global climate negotiations, our Government is yet to announce its contribution to international climate finance for 2025-2030. Greenpeace recommends a commitment of $11 billion for this five year period, which is aligned with the global goal under the Paris Agreement to triple international climate finance from current levels.
This new commitment should include additional funding to address loss and damage from climate change and a substantial contribution to the Pacific Resilience Facility, ensuring support is accessible to countries and communities that need it most. It should also see Australia get firmly behind the vision of a Fossil Fuel Free Pacific.
7. Protect nature

There is no safe planet without protection of the ecosystems and biodiversity that sustain us and regulate our climate.
Last year the Parliament passed important and long overdue reforms to our national environment laws to ensure better protection for our forests and other critical ecosystems. However, the Government will need to provide sufficient funding to ensure the effective implementation of these reforms.
Greenpeace has recommended $500 million over four years to establish the National Environment Agency — the body responsible for enforcing and monitoring the new laws — and a further $50 million to Environment Information Australia for providing critical information and tools.
Further resourcing will also be required to fulfil the crucial goal of fully protecting 30% of Australian land and seas by 2030. This should include $1 billion towards ending deforestation by enabling farmers and loggers to retool away from destructive practices, $2 billion a year for restoring degraded lands, $5 billion for purchasing and creating new protected areas, and $200 million for expanding domestic and international marine protected areas.
Conclusion
This is not the first time that conflict overseas has triggered an energy crisis, or that a budget has been preceded by a summer of extreme weather disasters, highlighting the urgent need to phase out fossil fuels. What’s different in 2026 is the availability of solutions. Renewable energy is now cheaper and more accessible than ever before. Global momentum is firmly behind the transition away from fossil fuels. The Albanese Government, with its overwhelming majority, has the chance to set our nation up for the future, or keep us stranded in the past. Let’s hope it makes some smart choices.

What fossil fuels really cost us in a world at war
Anne Jellema is Executive Director of 350.org.
The war on Iran and Lebanon is a deeply unjust and devastating conflict, killing civilians at home, destroying lives, and at the same time sending shockwaves through the global economy. We, at 350.org, have calculated, drawing on price forecasts from the International Monetary Fund (IMF) and Goldman Sachs, just how much that volatility is costing us.
Even under the IMF’s baseline scenario – a de facto “best case” scenario with a near-term end to the war and related supply chain disruptions – oil and gas price spikes are projected to cost households and businesses globally more than $600 billion by the end of the year. Under the IMF’s “adverse scenario”, with prolonged conflict and sustained price pressures, we estimate those additional costs could exceed $1 trillion, even after accounting for reduced demand.
Which is why we urgently need a power shift. Governments are under growing pressure to respond to rising fuel and food costs and deepening energy poverty. And it’s becoming clearer to both voters and elected officials that fossil dependence is not only expensive and risky, but unnecessary.
People who can are voting with their wallets: sales of solar panels and electric vehicles are increasing sharply in many countries. But the working people who have nothing to spare, ironically, are the ones stuck with using oil and gas that is either exorbitantly expensive or simply impossible to get.
Drain on households and economies
In India, street food vendors can’t get cooking gas and in the Philippines, fishermen can’t afford to take their boats to sea. A quarter of British people say that rising energy tariffs will leave them completely unable to pay their bills. This is the moment for a global push to bring abundant and affordable clean energy to all.
In April, we released Out of Pocket, our new research report on how fossil fuels are draining households and economies. We were surprised by the scale of what we found. For decades, governments have reassured people that energy price spikes are unfortunate but unavoidable – the result of distant conflicts, market forces or geopolitical shocks beyond anyone’s control. But the numbers tell a different story.
What we are living through today is not an energy crisis. It is a fossil fuel crisis. In just the first 50 days of the Middle East conflict, soaring oil and gas prices have siphoned an estimated $158 billion–$166 billion from households and businesses worldwide. That is money extracted directly from people’s pockets and transferred, almost instantly, into fossil fuel company balance sheets. And this figure only captures the immediate impact of price spikes, not the permanent economic drain of fossil dependence. Fossil fuels don’t just cost us once, they cost us over and over again.
First, through our bills. Every time there is a war, an embargo or a supply disruption, fossil fuel prices surge. For ordinary people, this means higher costs for energy, transport and food. Many Global South countries have little or no fiscal space to buffer the shock; instead, workers and families pay the price.
Second, through our taxes. Governments around the world continue to pour vast sums of public money into fossil fuel subsidies. These are often justified as a way to protect the most vulnerable at the petrol pump or in their homes. But in reality, the benefits are overwhelmingly captured by wealthier households and corporations. The poorest 20% receive just a fraction of this support, while public finances are drained.
Third, through climate impacts. New research across more than 24,000 global locations gives a granular account of the true costs of extreme heat, sea level rise and falling agricultural yields. Using this data to update IMF modelling of the social cost of carbon, we found that fossil fuel impacts on health and livelihoods amount to over $9 trillion a year. This is the biggest subsidy of all, because these massive and mounting costs are not charged to Big Oil – they are paid for by governments and households, with the poorest shouldering the lion’s share.
Massive transfer of wealth to fossil fuel industry
Adding up direct subsidies, tax breaks and the unpaid bill for climate damages, the total transfer of wealth from the public to the fossil fuel industry amounts to $12 trillion even in a “normal” year without a global oil shock. That’s more than 50% higher than the IMF has previously estimated, and equivalent to a staggering $23 million a minute.
The fossil fuel industry has become extraordinarily adept at profiting from instability. When conflict drives up prices, companies do not lose, they gain. In the current crisis, oil producers and commodity traders are on track to secure tens of billions of dollars in additional windfall profits, even as households face rising bills and governments struggle to manage the fallout.
Fossil fuel crisis offers chance to speed up energy transition, ministers say
This growing disconnect is impossible to ignore. Investors are advised to buy into fossil fuel firms precisely because of their ability to generate profits in times of crisis. Meanwhile, ordinary people are told to tighten their belts.
In 2026, unlike during the oil shocks of the 1970s, clean energy is no longer a distant alternative. Now, even more than when gas prices spiked due to Russia’s invasion of Ukraine in 2022, renewables are often the cheapest option available. Solar and wind can be deployed quickly, at scale, and without the volatility that defines fossil fuel markets.
How to transition from dirty to clean energy
The solutions are clear. Governments must implement permanent windfall taxes on fossil fuel companies to ensure that extraordinary profits generated during crises are redirected to support households. These revenues can be used to reduce energy bills, invest in public services, and accelerate the rollout of clean energy.
Second, we must shift subsidies away from fossil fuels and towards renewable solutions, particularly those that can be deployed quickly and equitably, such as rooftop and community solar. This is not just about cutting emissions. It is about building a more stable, fair and resilient energy system.
Finally, we need binding plans to phase out fossil fuels altogether, replacing them with homegrown renewable energy that can shield economies from future shocks. Because what the current crisis has made clear is this: as long as we remain dependent on fossil fuels, we remain vulnerable – to conflict, to price volatility and to the escalating impacts of climate change.
The true price of fossil fuels is no longer hidden. It is visible in rising bills, strained public finances and communities pushed to the brink. And it is being paid, every day, by ordinary people around the world.
It’s time for the great power shift.
Full details on the methodology used for this report are available here.
The Great Power Shift is a new campaign by 350.org global campaign to pressure governments to bring down energy bills for good by ending fossil fuel dependence and investing in clean, affordable energy for all

Traditional models still ‘outperform AI’ for extreme weather forecasts
Computer models that use artificial intelligence (AI) cannot forecast record-breaking weather as well as traditional climate models, according to a new study.
It is well established that AI climate models have surpassed traditional, physics-based climate models for some aspects of weather forecasting.
However, new research published in Science Advances finds that AI models still “underperform” in forecasting record-breaking extreme weather events.
The authors tested how well both AI and traditional weather models could simulate thousands of record-breaking hot, cold and windy events that were recorded in 2018 and 2020.
They find that AI models underestimate both the frequency and intensity of record-breaking events.
A study author tells Carbon Brief that the analysis is a “warning shot” against replacing traditional models with AI models for weather forecasting “too quickly”.
AI weather forecasts
Extreme weather events, such as floods, heatwaves and storms, drive hundreds of billions of dollars in damages every year through the destruction of cropland, impacts on infrastructure and the loss of human life.
Many governments have developed early warning systems to prepare the general public and mobilise disaster response teams for imminent extreme weather events. These systems have been shown to minimise damages and save lives.
For decades, scientists have used numerical weather prediction models to simulate the weather days, or weeks, in advance.
These models rely on a series of complex equations that reproduce processes in the atmosphere and ocean. The equations are rooted in fundamental laws of physics, based on decades of research by climate scientists. As a result, these models are referred to as “physics-based” models.
However, AI-based climate models are gaining popularity as an alternative for weather forecasting.
Instead of using physics, these models use a statistical approach. Scientists present AI models with a large batch of historical weather data, known as training data, which teaches the model to recognise patterns and make predictions.
To produce a new forecast, the AI model draws on this bank of knowledge and follows the patterns that it knows.
There are many advantages to AI weather forecasts. For example, they use less computing power than physics-based models, because they do not have to run thousands of mathematical equations.
Furthermore, many AI models have been found to perform better than traditional physics-based models at weather forecasts.
However, these models also have drawbacks.
Study author Prof Sebastian Engelke, a professor at the research institute for statistics and information science at the University of Geneva, tells Carbon Brief that AI models “depend strongly on the training data” and are “relatively constrained to the range of this dataset”.
In other words, AI models struggle to simulate brand new weather patterns, instead tending forecast events of a similar strength to those seen before. As a result, it is unclear whether AI models can simulate unprecedented, record-breaking extreme events that, by definition, have never been seen before.
Record-breaking extremes
Extreme weather events are becoming more intense and frequent as the climate warms. Record-shattering extremes – those that break existing records by large margins – are also becoming more regular.
For example, during a 2021 heatwave in north-western US and Canada, local temperature records were broken by up to 5C. According to one study, the heatwave would have been “impossible” without human-caused climate change.
The new study explores how accurately AI and physics-based models can forecast such record-breaking extremes.
First, the authors identified every heat, cold and wind event in 2018 and 2020 that broke a record previously set between 1979 and 2017. (They chose these years due to data availability.) The authors use ERA5 reanalysis data to identify these records.
This produced a large sample size of record-breaking events. For the year 2020, the authors identified around 160,000 heat, 33,000 cold and 53,000 wind records, spread across different seasons and world regions.
For their traditional, physics-based model, the authors selected the High RESolution forecast model from the Integrated Forecasting System of the European Centre for Medium-Range Weather Forecasts. This is “widely considered as the leading physics-based numerical weather prediction model”, according to the paper.
They also selected three “leading” AI weather models – the GraphCast model from Google Deepmind, Pangu-Weather developed by Huawei Cloud and the Fuxi model, developed by a team from Shanghai.
The authors then assessed how accurately each model could forecast the extremes observed in the year 2020.
Dr Zhongwei Zhang is the lead author on the study and a researcher at Karlsruhe Institute of Technology. He tells Carbon Brief that many AI weather forecast models were built for “general weather conditions”, as they use all historical weather data to train the models. Meanwhile, forecasting extremes is considered a “secondary task” by the models.
The authors explored a range of different “lead times” – in other words, how far into the future the model is forecasting. For example, a lead time of two days could mean the model uses the weather conditions at midnight on 1 January to simulate weather conditions at midnight on 3 January.
The plot below shows how accurately the models forecasted all extreme events (left) and heat extremes (right) under different lead times. This is measured using “root mean square error” – a metric of how accurate a model is, where a lower value indicates lower error and higher accuracy.
The chart on the left shows how two of the AI models (blue and green) performed better than the physics-based model (black) when forecasting all weather across the year 2020.
However, the chart on the right illustrates how the physics-based model (black) performed better than all three AI models (blue, red and green) when it came to forecasting heat extremes.

The authors note that the performance gap between AI and physics-based models is widest for lower lead times, indicating that AI models have greater difficulty making predictions in the near future.
They find similar results for cold and wind records.
In addition, the authors find that AI models generally “underpredict” temperature during heat records and “overpredict” during cold records.
The study finds that the larger the margin that the record is broken by, the less well the AI model predicts the intensity of the event.
‘Warning shot’
Study author Prof Erich Fischer is a climate scientist at ETH Zurich and a Carbon Brief contributing editor. He tells Carbon Brief that the result is “not unexpected”.
He adds that the analysis is a “warning shot” against replacing traditional models with AI models for weather forecasting “too quickly”.
The analysis, he continues, is a “warning shot” against replacing traditional models with AI models for weather forecasting “too quickly”.
AI models are likely to continue to improve, but scientists should “not yet” fully replace traditional forecasting models with AI ones, according to Fischer.
He explains that accurate forecasts are “most needed” in the runup to potential record-breaking extremes, because they are the trigger for early warning systems that help minimise damages caused by extreme weather.
Leonardo Olivetti is a PhD student at Uppsala University, who has published work on AI weather forecasting and was not involved in the study.
He tells Carbon Brief that “many other studies” have identified issues with using AI models for “extremes”, but this paper is novel for its specific focus on extremes.
Olivetti notes that AI models are already used alongside physics-based models at “some of the major weather forecasting centres around the world”. However, the study results suggest “caution against relying too heavily on these [AI] models”, he says.
Prof Martin Schultz, a professor in computational earth system science at the University of Cologne who was not involved in the study, tells Carbon Brief that the results of the analysis are “very interesting, but not too surprising”.
He adds that the study “justifies the continued use of classical numerical weather models in operational forecasts, in spite of their tremendous computational costs”.
Advances in forecasting
The field of AI weather forecasting is evolving rapidly.
Olivetti notes that the three AI models tested in the study are an “older generation” of AI models. In the last two years, newer “probabilistic” forecast models have emerged that “claim to better capture extremes”, he explains.
The three AI models used in the analysis are “deterministic”, meaning that they only simulate one possible future outcome.
In contrast, study author Engelke tells Carbon Brief that probabilistic models “create several possible future states of the weather” and are therefore more likely to capture record-breaking extremes.
Engelke says it is “important” to evaluate the newer generation of models for their ability to forecast weather extremes.
He adds that this paper has set out a “protocol” for testing the ability of AI models to predict unprecedented extreme events, which he hopes other researchers will go on to use.
The study says that another “promising direction” for future research is to develop models that combine aspects of traditional, physics-based weather forecasts with AI models.
Engelke says this approach would be “best of both worlds”, as it would combine the ability of physics-based models to simulate record-breaking weather with the computational efficiency of AI models.
Dr Kyle Hilburn, a research scientist at Colorado State University, notes that the study does not address extreme rainfall, which he says “presents challenges for both modelling and observing”. This, he says, is an “important” area for future research.
