The UK would be able to increase its emissions while still meeting its next legally binding climate goal if the government uses a “surplus” to weaken the target, official advisers warn.

The government has asked the Climate Change Committee (CCC) if it should carry over “surplus” emissions, after the UK overachieved the third “carbon budget” for 2018-2022.

This surplus is equivalent to an extra year’s worth of emissions, so carrying it forward would increase the size of the fourth carbon budget for 2023-2027 by a fifth.

Doing so would make it far easier for the next government to meet that budget, allowing emissions to rise by around 15% from current levels – instead of falling towards net-zero.

In a letter, published today, the Climate Change Committee (CCC) says its “unequivocal” advice is that doing this would place the UK’s future climate goals at “very serious risk” and would make the 2050 net-zero target “more expensive and harder to achieve”.

The letter says that the surplus is largely the result of a sluggish economy and the impact of Covid-19. The committee emphasises that the UK’s emissions cuts need to accelerate to stay on course for long-term goals, rather than slow down.

‘Surplus’ emissions cuts

Under the Climate Change Act, the UK must hit legally binding interim emissions targets, known as carbon budgets, that get gradually lower on a pathway to net-zero emissions by 2050.

Earlier this month, the government published final greenhouse gas emissions figures showing that the UK overachieved in its third carbon budget. Total net emissions were 2,153m tonnes of carbon dioxide equivalent (MtCO2e) between 2018 and 2022, the figures show, against a target of 2,544MtCO2e. 

This means the UK came in 391MtCO2e – or 15% – below the budget for this five-year period. This “overachievement”, largely due to the impact of the Covid-19 pandemic and other external factors (see below), is equivalent to around one year of UK emissions.

Earlier this month, UK climate minister Graham Stuart asked the CCC for its view on “carrying forward” the emissions “surplus” to the next carbon budget.

Under section 17 of the Climate Change Act, the government is legally entitled to do this if it wishes, but must first seek and take into account the CCC’s advice.

Carrying forward some or all of the surplus effectively weakens the UK’s next carbon budget, by an equivalent amount. Nevertheless, the flexibility was included in the Climate Change Act in order to encourage – and reward – early action to cut emissions.

Five years ago, the CCC issued a similar warning that the UK should not carry forward the surplus from the second carbon budget to the third period, because that overachievement was also largely due to external factors rather than genuine early action.

However, the government ignored the CCC’s advice – the first time it had done so – and carried forward 88MtCO2e into the third carbon budget.

Today, the CCC has once again written to the government warning it not to weaken the fourth carbon budget by making use of surplus emissions.

Indeed, as the chart below shows, making full use of the third budget surplus would allow the UK to legally increase its emissions in the current fourth carbon budget period 2024-2027, rather than cutting them in line with its longer-term goals. 

UK emissions could rise by 15% if government uses 'surplus' to weaken target

The red line indicates the maximum emissions that could legally be allowed if the “surplus” emissions from the third carbon budget are carried forward into the fourth budget period. The “delivery pathway” is an indicative pathway from the CCC based on the government’s carbon budget delivery plan, showing the path the government intends to take to meet the target of net-zero by 2050. Projected shares of emissions from international aviation and shipping (IAS) have been removed from the delivery pathway, to bring it in line with the historical emissions figures. Unlike earlier carbon budgets, the sixth carbon budget includes IAS emissions. Source: CCC, DESNZ, Carbon Brief analysis.

With the third carbon budget surplus of 391MtCO2e being equivalent to a whole extra year of emissions in the UK, the country could emit around 20% more over the five-year budget than the amount officially legislated.

Adding this amount to the fourth carbon budget would enable the UK to emit 200MtCO2e more between 2023-27 than it did over the course of its third carbon budget, following decades of relatively consistent cuts.

This would amount to a 9% increase in emissions between budgets and an increase of as much as 15% from 2022 levels, across the fourth budget period.

It would also push the UK far off course from the government’s own carbon budget delivery plan for meeting near- and long-term targets, which it set out last year. 

If the government decides to carry over the surplus and emissions are allowed to rise to their maximum level under a looser fourth carbon budget, getting back on track for the fifth carbon budget would require a “huge and impractical” total emissions reduction of 1,036MtCO2e over the following five years, according to the CCC.

This is twice as fast as anticipated in the government’s plan – and 40% quicker than the most ambitious scenario devised by the CCC.

‘Very serious risk’

In light of these potential outcomes, interim CCC chair Prof Piers Forster writes in his response to Stuart’s request that the surplus should not be used:

“The committee’s unequivocal advice is that surplus emissions from the third carbon budget should not be carried forward.”

The committee warns against “setting conditions that allow for a legally compliant slowdown in progress” when the focus “should be on accelerating and broadening emissions reductions”.

It concludes that both the UK’s domestic goal of the sixth carbon budget for 2033-37 and its 2030 international climate target under the Paris Agreement would be placed at “very serious risk” if the carryover is allowed.

The fourth carbon budget was set when the UK’s 2050 emissions goal was an 80% reduction rather than 100%. This means that the government should be overachieving, rather than underachieving, on the budget’s target emissions reductions in order to stay on a “sensible” track for its future goals, according to the CCC.

The CCC’s response reiterates its previous recommendations to Stuart’s predecessors about carrying forward surplus from the first and second carbon budgets.

Moreover, the committee points out that “most” of the surplus emissions cuts in recent years have not been the result of the government’s climate policies.

According to the committee, roughly half of them resulted from a “tighter than expected” EU ETS cap. This meant “less was required” of government policy in areas outside of the ETS, such as transport and heating buildings.

Most of the remaining surplus is accounted for by “lower-than-expected GDP” and less travel due to the Covid-19 pandemic, the CCC adds.

The CCC emphasises the need for continued incentives and pressure to make emissions cuts across all sectors, concluding:

“The Climate Change Act and the carbon budgets provide a clear, longrun signal to investors and businesses on the UK’s decarbonisation trajectory. Carrying forward the third carbon budget surplus would weaken this message, causing uncertainty, and could ultimately result in net-zero being more expensive and harder to achieve.”

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

Published

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.
