Billions of dollars of foreign aid have been reclassified as “climate finance”, thereby helping rich countries to meet a long-overdue target, according to new analysis.

Newly released figures suggest that developed nations achieved their goal of raising $100bn in climate aid for developing countries in 2022 – two years after the deadline.

The Organisation for Economic Co-operation and Development (OECD) says these countries raised $115.9bn for climate-related projects, following a record surge in spending.

However, analysis conducted by the Center for Global Development (CGD) and shared with Carbon Brief suggests that around $27bn of the $94.2bn increase in public climate funds over the past two decades came from existing development aid.

Specifically, the CGD identified at least $6.5bn of climate aid within the record 2022 increase that was diverted from other aid programmes. This is despite pledges by wealthy countries to provide climate finance that is “new and additional”. 

Such accounting changes could allow some developed countries to reach their climate targets, even while slashing their wider aid budgets

Meanwhile, wealthy nations are under pressure to rapidly increase climate spending in the global south. At COP29 this year, all parties must agree on a new climate target that will help raise the trillions of dollars these nations say they need to address climate change. 

‘Largest increase’

The $100bn target was set in 2009 at COP15 in Copenhagen to help developing countries cut their emissions and protect themselves from climate change.

A group of “developed” countries, including many European nations, the US, Canada, Japan, Australia and New Zealand, agreed to “mobilise” this amount by 2020 and then each year through to 2025.

This money largely comes from countries’ foreign-aid budgets, which finance climate-related development projects. A smaller proportion is also raised from the private sector.

Crucially, countries have determined during UN climate negotiations that climate finance should be “new and additional”. This is generally interpreted as meaning it should be supplied on top of existing aid.

Developed countries failed to hit the $100bn goal by 2020, raising just $83.3bn that year. This was poorly received by developing country governments, who view this money as essential to meet their climate targets under the Paris Agreement

Last year, the OECD, which tracks international climate finance, announced that developed countries had “likely” met the target in 2022 – two years late. It did not release the data underpinning this estimate at the time.

The OECD has now published a report confirming that the $100bn goal was met. In fact, the organisation says climate finance underwent its “largest year-on-year increase observed to date” in 2022 – reaching $115.9bn. This $26.3bn increase can be seen in the chart below.

This uptick in climate finance was driven by record increases in spending both bilaterally – directly from country-to-country – and via multilateral development banks and funds.

There was also an unprecedented $7.5bn increase in private finance, which was mobilised by developed country investment. This comes after years of private investment remaining essentially unchanged each year.

The OECD notes that the “lion’s share” of public climate finance was provided as loans – around 69% of the total. This has raised concerns, given the number of global south countries that are already struggling with debt

‘New and additional’

Countries are set to decide on a new climate-finance goal – known as the “new collective quantified goal” – at COP29 in Baku, Azerbaijan, later this year. This target is expected to go beyond the $100bn goal and be based on an assessment of countries’ real-world needs.

Meanwhile, some wealthy countries have announced major cuts to their foreign-aid budgets. Many nations have also decided to channel large amounts of aid to Ukraine, following Russia’s invasion in 2022, while also diverting funds to accommodate refugees on their own soil. 

All of this could squeeze the wider development-aid budget and, in theory, make achieving climate finance goals more challenging.

Some countries, including the UK, have opted to meet their climate finance targets by “redirecting” or “relabelling” existing funds as “climate finance”, while failing to commit new money in sufficient volumes.

According to analysis by the CGD – released one week ahead of the OECD’s assessment – this is largely what enabled developed countries to meet the $100bn target in 2022.

It concluded that, when considering public climate finance, the goal was “partly achieved by adding climate objectives to existing development finance flows”. (The CGD analysis did not attempt to estimate the increase in private finance, assuming it would remain stable as it had in previous years.)

Applying the CGD analysis to the public portion of the OECD’s $115.9bn climate finance figure – which amounted to $94.2bn – shows that around $27bn comes from existing development aid.

This is based on overall aid only increasing $67.2bn between 2009 and 2022, meaning the remaining increase in climate aid must have come from existing sources.

Ian Mitchell, the CGD senior policy fellow who led the analysis, tells Carbon Brief:

“The intention was to provide ‘new and additional’ finance and I think the very lowest bar for that is that the face value of [total] finance would have gone up $100bn.”

As the chart below shows, while the overall aid budget grew in 2022, due partly to new aid for Ukraine and more spending on housing refugees, existing bilateral development aid fell in 2022.

Given this, the CGD says the $6.5bn increase in climate finance that year can definitively be attributed to countries’ existing foreign-aid budgets, rather than an increase in spending.

Diverting funds

Mitchell highlights the key issue with hitting climate finance targets without committing enough new resources:

“The problem with meeting that $100bn from existing resources is that it’s either rebadging it, which is not providing climate finance, or it’s diverting it from other development objectives…reducing spend on health or education.”

However, Joe Thwaites, senior international climate finance advocate at the Natural Resources Defense Council (NRDC), tells Carbon Brief that not all diversions are “bad diversions”.  

A report by the thinktank ODI last year found that much of the funding being reclassified came from sectors such as energy and transport. Thwaites points out that this could mean cutting back on support for fossil fuels and targeting clean energy instead:

“Given the massive development and climate needs, we need to be growing the overall international public-finance pie. But shifting finance from one area to another isn’t necessarily a bad thing, it all depends what it’s being taken from and going to.”

More broadly, Harjeet Singh, global climate lead at Climate Action Network (CAN) International, tells Carbon Brief that developed countries are taking advantage of “creative accounting” and “fiscal loopholes” to meet their targets. 

He warns that, as nations prepare to negotiate a new climate finance target at COP29, there is a need for a clear definition of what counts as “climate finance” to avoid such behaviour:

“The absence of a unified definition of climate finance is not a mere oversight; it mirrors historical patterns of power…Developed countries have aimed to keep their financial responsibilities ambiguous.”

DeBriefed 10 October 2025: Renewables power past coal; Legacy of UK’s Climate Change Act; Fukushima’s solar future

Published

on

Welcome to Carbon Brief’s DeBriefed.
An essential guide to the week’s key developments relating to climate change.

This week

Renewables overtake coal

‘HISTORIC FIRST’: Renewables have overtaken coal to become the world’s leading source of electricity for the first six months of this year in a “historic first”, BBC News said. The analysis, from the thinktank Ember, found the world generated “almost a third” more solar power in the first half of the year, compared with the same period in 2024, while wind power grew by “just over 7%,” reported the Guardian.

HEAVY LIFTING: According to the report, China and India were “largely responsible for the surge in renewables”, while the US and Europe “relied more heavily on fossil fuels,” the Guardian wrote. China built more renewables than every other country combined in the first half of this year, the newspaper added.

CONTINENTAL SHIFTS: A second report from the International Energy Agency (IEA) predicted a “surge” in global wind and solar capacity by 2030, but shaved 5% off its previous forecast, the Financial Times said. The IEA revealed that India is set to become the second-largest growth market for renewables after China, “with capacity expected to increase 2.5 times by 2030”, Down to Earth reported. The IEA also upped its forecast for renewables in the Middle East and north Africa by 23%, “helped by Saudi Arabia rolling out wind turbines and solar panels”, but halved the outlook for the US, the FT noted.

Around the world

  • EV BOOM: Sales of electric and hybrid cars made up “more than half” of all new car registrations in the UK last month, a new record, according to data from the Society of Motor Manufacturers, reported BBC News.
  • BANKING COLLAPSE: A global banking alliance launched by the UN to get banks to slash the carbon footprint of their loans and investments and help drive the transition to a net-zero economy by 2050 has collapsed after four years, Agence France-Press reported.
  • CUTS, CUTS, CUTS: The Trump administration plans to cut nearly $24bn in funding for more than 600 climate projects across the US, according to documents reviewed by the Wall Street Journal.
  • PEOPLE POWER: A farmer, a prison guard and a teacher were among those from the Dutch-Caribbean island Bonaire who appeared at the Hague on Tuesday to “accuse the Netherlands of not doing enough to protect them from the effects of climate change”, Politico reported.

UK_Climate_Change_Act_DeBriefed

The UK’s Climate Change Act, landmark legislation that guides the nation’s response to climate change, is increasingly coming under attack from anti-net-zero right-leaning politicians. In a factcheck published this week, Carbon Brief explained how the UK’s Climate Change Act was among the first comprehensive national climate laws in the world and the first to include legally binding emissions targets. In total, 69 countries have now passed “framework” climate laws similar to the UK’s Climate Change Act, with laws in New Zealand, Canada and Nigeria among those explicitly based on the UK model. This is up from just four when the act was legislated in 2008. Of these, 14 are explicitly titled the “Climate Change Act”.

Spotlight

Fukushima’s solar future

This week, Carbon Brief examines how Fukushima helped to recover from nuclear disaster by building solar farms on contaminated farmland.

On 11 March 2011, an earthquake off the pacific coast of Japan caused 15m-tall waves to crash into the eastern region of Tōhoku, killing 19,500 people and injuring a further 6,000.

In the aftermath, flooding at the Fukushima Daichi nuclear power plant caused cooling systems to fail, leaching radioactive contaminants into the soil and leading to a major nuclear incident.

Some 1,200km2 around the site was restricted and up to 100,000 people were evacuated – in some cases forever.

In the years following, Japan entered a fraught debate about nuclear energy.

In 2010, nuclear power provided 25% of Japan’s electricity, but, in the years following the disaster, its 54 nuclear reactors were taken offline.

Successive governments have fought over reintroducing nuclear power. Today, some 14 reactors are back online, 27 have been permanently closed and another 19 remain suspended. (Japan’s newly-elected prime minister Sanae Takaichi has promised to make nuclear central to her energy strategy.)

Against this backdrop, Fukushima – a prefecture home to 1.8 million people – has emerged as a surprise leader in the renewables race.

In 2014, the Fukushima Renewable Energy Institute (FREA) opened with the twin goals of promoting research and development into renewable energy, while “making a contribution to industrial clusters and reconstruction”.

That same year, the prefecture declared a target of 100% renewable power by 2040.

Contaminated land

“A lot of these communities, I know, were looking for ways to revitalise their economy,” said Dr Jennifer Sklarew, assistant professor of energy and sustainability at George Mason University and author of “Building Resilient Energy Systems: Lessons from Japan”.

Once evacuation orders were lifted, however, residents in many parts of Fukushima were faced with a dilemma, explained Skarlew:

“Since that area was largely agricultural, and the agriculture was facing challenges due to stigma, and also due to the soil being removed [as part of the decontamination efforts], they had to find something else.”

One solution came in the form of rent, paid to farmers by companies, to use their land as solar farms.

Michiyo Miyamoto, energy finance specialist at the Institute for Energy Economics and Financial Analysis, told Carbon Brief:

“The [Fukushima] prefecture mapped suitable sites early and conducted systematic consultations with residents and agricultural groups before projects were proposed. This upfront process reduced land-use conflicts, shortened permitting timelines and gave developers clarity.”

As a result, large-scale solar capacity in Fukushima increased to more than 1,300 megawatts (MW) from 2012 to 2023, according to Miyamoto. Moreover, installed renewable capacity now exceeds local demand, meaning the region can run entirely on clean power when conditions are favourable, Miyamoto said.

Today, aerial pictures of Fukushima reveal how solar panels have proliferated on farmland that was contaminated in the nuclear disaster.

Charging on

Last year, 60% of Fukushima’s electricity was met by renewables, up from 22% in 2011. (The country as a whole still lags behind at 27%.)

And that is set to grow after Japan’s largest onshore windfarm started operations earlier this year in Abukuma, Fukushima, with a capacity of 147MW.

The growth of solar and wind means that Fukushima is already “ahead of schedule” for its 2040 target of 100% renewable power, said Miyamoto:

“The result is a credible pathway from recovery to leadership, with policy, infrastructure and targets working in concert.”

Guest post: How Caribbean states are shifting climate legislation

Published

on

The Caribbean region is among the most vulnerable to climate change, despite historically contributing less than half of one percent of global greenhouse gas emissions.

Rising sea levels, extreme heat and more frequent and intense storms – such as the 2024 Hurricane Beryl, which made landfall in Grenada – pose urgent and growing threats to the small island states, coastal nations and overseas territories that comprise the Caribbean region.

With global progress to address climate change still too slow, Caribbean countries are taking matters into their own hands by enacting more robust legislation to help protect against climate risks.

In a new study published in the Carbon and Climate Law Review, we identified 78 climate laws and legally binding decrees across 16 Caribbean states, as well as two constitutional references to climate change and a growing recognition of the right to a healthy environment.

Our analysis suggests that, together, these developments are not only enhancing resilience, but also positioning Caribbean states as influential actors in the global climate arena.

Caribbean climate laws on the rise

Climate governance in the Caribbean has expanded significantly in recent years. In the past decade, countries such as Cuba and the Dominican Republic have embedded climate obligations and programmatic guidelines into their national constitutions.

At the same time, legislative recognition of the human right to a healthy environment is gaining momentum across the region. Six Caribbean nations now affirm the right in their constitutions, while 15 have recognised it through international instruments, such as the UN Council, UN Assembly and the Escazu Agreement, as shown in the figure below.

More recently, there has been a notable rise in targeted, sector-specific climate frameworks that go beyond broader environmental statutes.

Saint Lucia stands out as the only country with a climate framework law, or a comprehensive national law that outlines long-term climate strategies across multiple domains. Meanwhile, several other Caribbean governments have adopted climate-specific laws that focus on individual sectors, such as energy, migration and disaster management.

According to our analysis, more than a quarter of climate-relevant legislation in the region – comprising 21 laws and legally binding decrees – now has an explicit focus on climate change, as illustrated in the chart below.

Our research suggests that this represents an ongoing shift in legislative focus, reflecting changes in how climate legislation is being structured in one of the world’s most climate-vulnerable regions.

Caribbean nations are also advancing legal reforms to structure and institutionalise climate finance and market mechanisms directly into domestic law, aligned with Article 6.2 of the Paris Agreement.

For example, the Bahamas has introduced provisions for carbon credit trading, while Antigua and Barbuda, Barbados and Grenada have established national climate financing mechanisms to support mitigation and adaptation efforts.

Some states, including Belize and Saint Kitts and Nevis, have incorporated regional bodies such as the Caribbean Community Climate Change Centre – the climate arm of the intergovernmental Caribbean community organisation CARICOM – into national frameworks. This indicates an increasing alignment between regional cooperation and domestic law.

In addition to the influx of regulations specifically addressing climate change, Caribbean nations are also legislating broader environmental issues, which, in turn, could provide increased resilience from climate impacts and risks, as shown in the graph above.

Key trends in these types of climate-related laws include the expansion of disaster risk management governance, which addresses national preparedness for climate-induced weather events or related catastrophes. Likewise, energy law is an increasingly prominent focus, with countries including Antigua and Barbuda and Saint Vincent and the Grenadines integrating renewable energy and energy efficiency goals into national climate governance.

More broadly, many Caribbean nations have adopted wide-ranging and comprehensive environmental laws, many of which were developed in alignment with existing climate commitments. In combination, these legal developments reflect a dynamic and evolving climate governance landscape across the region.

Proactive vs reactive approaches

Despite general alignment with these broader regional trends, our research reveals distinct developmental pathways shaping domestic climate regulation.

In the eastern Caribbean, for example, we saw both proactive, long-term planning strategies and reactive, post-disaster reforms.

Saint Lucia’s multifaceted approach to climate resilience evolved steadily over the course of more than a decade. During this time, the country developed numerous adaptation plans, strengthened cross-sectoral coordination and engaged in institutional climate reforms in areas such as energy, tourism, finance and development.

More recently, the passage of Saint Lucia’s Climate Change Act in 2024 marked a milestone in climate governance, by giving legal force to the country’s obligations under the UNFCCC, the Kyoto Protocol and the Paris Agreement – making Saint Lucia one of the few small island states to incorporate global climate commitments into domestic law.

Our research indicates that this strategy has not only positioned the country as a more climate-resilient nation, but also solidified its access to international climate financing.

In contrast, Dominica’s efforts evolved more rapidly in the aftermath of Hurricane Maria in 2017, which destroyed over 200% of the country’s GDP. The storm’s impacts were felt across the country and hit particularly hard for the Kalinago people – the Caribbean’s last Indigenous community – highlighting the role of socioeconomic disparities in shaping climate vulnerability and resilience.

In response, the government passed the Climate Resilience Act, creating the temporary Climate Resilience Execution Agency for Dominica (CREAD).

Beyond establishing an exclusively climate-focused institution, the act aimed to embed resilience into governance by mandating the participation of vulnerable communities – including Indigenous peoples, women, older people and people with disabilities – in shaping and monitoring climate resilience projects.

As noted in a recent statement by the UN special rapporteur on Climate Change, Dr Elisa Morgera, these frameworks underscore the government’s ambition to become the world’s first “climate-resilient nation.”

Although challenges persist, Dominica’s efforts demonstrate how post-disaster urgency can drive institutional change, including the integration of rights and resilience into climate governance.

Uneven progress and structural gaps

Despite significant progress, our research shows that several key opportunities for climate governance across the Caribbean continue to exist, which could enable improvements in both resilience and long-term ambition.

The region’s legal landscape remains somewhat heterogeneous. While Saint Lucia has enacted a comprehensive climate framework law, the rest of the region lacks similar blanket legislation. This includes some states that entirely lack climate-specific laws, instead relying on related laws and frameworks to regulate and respond to climate-related risks.

Other nations have yet to adopt explicit disaster-risk management frameworks, leaving Caribbean populations vulnerable before, during and after climate emergencies. Most have yet to enshrine the right to a healthy environment at the national level.

Our research suggests that outdated legal frameworks are further limiting progress in addressing current climate risks. Because many of the longer-standing environmental laws in the region were adopted well before climate policy became a mainstream concern, some fail to address the nature, frequency and intensity of modern climate challenges, such as sea-level rise, tropical storms, wildfires, floods, droughts and other impacts.

More broadly, many Caribbean climate laws include limited integration of gender equity, Indigenous rights and social justice. As Caribbean nations such as Grenada and the Dominican Republic begin to link climate resilience with these issues, the region has an opportunity to lead by example.

Ultimately, capacity and resource constraints persist as significant barriers to implementation and adaptation.

The Caribbean region faces debt that exacerbates ongoing development challenges, a burden made heavier by the repeated economic shocks of climate-related disasters. Along with regional debt-for-resilience schemes, increased funding from high-emitting countries to support adaptation measures in climate-vulnerable nations – as endorsed under the Paris Agreement – is likely to be critical to ensuring the region’s climate laws can be executed effectively.

Global implications of Caribbean climate law

Our research suggests that Caribbean countries are outpacing other regions in terms of the scope and ambition of their climate laws. This legislation has the potential to serve as a model for climate-vulnerable nations worldwide.

Continuing efforts in the region show that legal frameworks in the field can not only drive resilience, embed rights and strengthen claims to international finance, but also highlight how regional cooperation and diplomacy can enhance global influence.

These findings demonstrate that innovation in climate law need not wait for action from major emitters, but can instead be led by those on the front lines of climate change.

IEA: Renewables have cut fossil-fuel imports for more than 100 countries

Published

on

More than 100 countries have cut their dependence on fossil-fuel imports and saved hundreds of billions of dollars by continuing to invest in renewables, according to the International Energy Agency (IEA).

It says nations such as the UK, Germany and Chile have reduced their need for imported coal and gas by around a third since 2010, mainly by building wind and solar power.

Denmark has cut its reliance on fossil-fuel imports by nearly half over the same period.

Renewable expansion allowed these nations to collectively avoid importing 700m tonnes of coal and 400bn cubic metres of gas in 2023, equivalent to around 10% of global consumption.

In doing so, the fuel-importing countries saved more than $1.3tn between 2010 and 2023 that would otherwise have been spent on fossil fuels from overseas.

Reduced reliance

The IEA’s Renewables 2025 report quantifies the benefits of renewable-energy deployment for electricity systems in fossil fuel-importing nations.

It compares recent trends in renewable expansion to an alternative “low renewable-energy source” scenario, in which this growth did not take place.

In this counterfactual, fuel-importing countries stopped building wind, solar and other non-hydropower renewable-energy projects after 2010.

In reality, the world added around 2,500 gigawatts (GW) of such projects between 2010 and 2023, according to the IEA, more than the combined electricity generating capacity of the EU and US in 2023, from all sources. Roughly 80% of this new renewable capacity was built in nations that rely on coal and gas imports to generate electricity.

The chart below shows how 31 of these countries have substantially cut their dependence on imported fossil fuels over the 13-year period, as a result of expanding their wind, solar and other renewable energy supplies. All of these countries are net importers of coal and gas.

In total, the IEA identified 107 countries that had reduced their dependence on fossil fuel imports for electricity generation, to some extent due to the deployment of renewables other than hydropower.

Of these, 38 had cut their reliance on electricity from imported coal and gas by more than 10 percentage points and eight had seen that share drop by more than 30 percentage points.

Security and resilience

The IEA stresses that renewables “inherently strengthen energy supply security”, because they generate electricity domestically, while also “improving…economic resilience” in fossil-fuel importer countries.

This is particularly true for countries with low or dwindling domestic energy resources.

The agency cites the energy crisis exacerbated by Russia’s invasion of Ukraine, which exposed EU importers to spiralling fossil-fuel prices.

Bulgaria, Romania and Finland – which have historically depended on Russian gas for electricity generation – have all brought their import reliance close to zero in recent years by building renewables.

In the UK, where there has been mounting opposition to renewables from right-wing political parties, the IEA says reliance on electricity generated with imported fossil fuels has dropped from 45% to under 25% in a decade, thanks primarily to the growth of wind and solar power.

Without these technologies, the UK would now be needing to import fossil fuels to supply nearly 60% of its electricity, the IEA says.

Other major economies, notably China and the EU, would also have had to rely on a growing share of coal and gas from overseas, if they had not expanded renewables.

As well as increasing the need for fossil-fuel imports from other countries, switching renewables for fossil fuels would require significantly higher energy usage “due to [fossil fuels’] lower conversion efficiencies”, the IEA notes. Each gigawatt-hour (GWh) of renewable power produced has avoided the need for 2-3GWh of fossil fuels, it explains.

Finally, the IEA points out that spending on renewables rather than imported fossil fuels keeps more investment in domestic economies and supports local jobs.
