Key developments

Climate leadership and cooperation

ENVOY REMARKS: Xinhua published an exclusive interview with Chinese climate envoy Liu Zhenmin, in which he spoke about how China-Europe cooperation could make a “positive contribution” to combating climate change. In the interview, Liu said that developed countries were “generally worried about who will share the responsibilities that the US should bear” after its withdrawal from the Paris Agreement, adding that China “deeply regretted” the “shrinking space” for US-China climate cooperation. The outlet quoted Liu saying: “However, we must see that China and the US do not have fundamental differences in the field of climate change, but rather have broad space for cooperation.”

EU AMBIVELANCE: Meanwhile, the EU’s ambassador to China, Jorge Toledo, warned that the EU may not hold an expected “high-level economic [and] trade dialogue” with China in July, due to current negotiations over Chinese EV tariffs and supply chains “not making progress”, reported the Hong Kong-based South China Morning Post (SCMP). European countries, such as the Netherlands, France and Germany, on the other hand, have expressed interest in more collaboration in areas such as climate and the low-carbon transition, said state-supporting media the Global Times. Belinda Schäpe, China policy analyst at Centre for Research on Energy and Clean Air (CREA), nevertheless wrote on LinkedIn that while both China and Germany “expressed support” for tackling climate change, it is “unclear how this will translate into Germany’s position on cooperation in areas like energy transition or climate diplomacy”.

EARLY PEAK?: China’s emissions will “likely peak a few years ahead of its self-set deadline of 2030”, Bloomberg said, reporting comments by Zhu Guangyao, who was the country’s vice minister of finance from 2010-2018 and who cited analysis recently published by Carbon Brief. The outlet quoted Zhu saying: “It’s most likely China will realise the peak of carbon emissions a few years before 2030…That’s good news for China, also good news for Asia, for the whole world.” Meanwhile, the SCMP published a comment article by former UN secretary general Ban Ki-moon on China’s “green energy leadership”. In the article, Ban called on China to target a 30% reduction in emissions below 2023 levels by 2035 in its next international climate pledge (nationally determined contribution, NDC).

New plan for ‘green’ manufacturing

上微信关注《碳简报》

‘GREEN TRANSFORMATION’: China’s central government approved an action plan for “advancing the green and low-carbon development” of the manufacturing sector between 2025 and 2027 at a State Council executive meeting, reported state news agency Xinhua. The full text of the action plan is not yet public. The meeting called for “deep[ening the] green transformation of traditional industries” while “accelerat[ing] innovation in green technologies”, added the outlet. The state-owned newspaper Securities Daily said that the policy extends “intensive” regulatory support and will affect a range of industries, including steel, metals and construction. About 20% of the “total output of China’s manufacturing industry” in 2024 had already come from “national-level green [factory] plants”, added the newspaper. (According to the “general principals” outlined by the Chinese government, such plants have tighter requirements on their emissions of greenhouse gases and other pollutants.)

RECTIFY THE ‘RAT RACE’: Meanwhile, the National Development and Reform Commission (NDRC) commented on “neijuan” (内卷) – officially translated as “rat race competition” that leads to oversupply in affected industries, including clean energy, steel and oil refining, reported Xinhua. According to the newswire, the NDRC said at its May press conference that this “rat race” had “disrupted” fair competition and “must be rectified”. According to the NDRC transcript, government officials called for eliminating “inefficient and backward production capacity” in the oil refining and steel industries, “preventing blind new construction” in the coal chemical and aluminium industries, and “guiding” “new-energy vehicle” (NEV) and solar companies to “focus on technology research and development”. Nevertheless, the officials stated that the majority of the investments the NDRC had approved from January to April this year were still in the “energy” and “advanced technology” sectors, among others, reported Chinese media outlet Dazhong News. The NDRC also said its “two new” policy “stimulated green consumption” of products such as NEVs, according to the transcript. Separately, the production of NEVs rose by 39% in April, said the Communist party-affiliated People’s Daily, adding that China’s “shift toward intelligent and green development is gaining momentum”.

‘Record’ solar added as policy deadline looms

SOLAR RUSH: China installed a “record” 105 gigawatts (GW) of solar capacity between January and April 2025, industry outlet PV Tech said, citing a recent data release by the National Energy Administration (NEA). It added that “April alone” accounted for 45GW of new additions – compared to a total of 46GW solar installations in China between January and March 2024 – as a deadline set by a new renewable pricing policy “triggered a project installation rush”. [Outside China, the US is the only country in the world to have more than 105GW of solar capacity in total. The UK has 18GW.]

THERMAL FALL: Analysis by thinktank Climate Energy Finance found that the amount of new solar installations between January and April was eight times larger than that of new thermal capacity (13GW, mainly coal). It added that China’s coal plants were only running 46% of the time on average in the first four months of 2025, saying that this was a “record low”. Similarly, Reuters reported that “thermal power generation in China, fuelled mainly by coal, fell 2% in April and 4% from January to April amid slower overall power output growth”. New data from energy thinktank Ember found that wind and solar power generated 26% of the country’s electricity in April 2025, the “highest monthly share on record”.

ROOFTOP ‘BOOM’: Meanwhile, separate data from consultancy Rystad Energy found that, of the 60GW of solar installed between January and March 2025, rooftop solar installations accounted for 36GW, marking the “highest quarterly total for distributed solar in [China’s] history”, solar news outlet PV Magazine reported. Industry news outlet SolarQuarter said that, according to Rystad Energy’s forecasts, the rooftop solar installation “boom” will continue through to June 2025, “potentially pushing total distributed solar capacity additions for the year to 130GW”.

SOLAR CYBER SCARE: Reuters reported that the US government is “reassessing the risk posed by Chinese-made” renewable energy components after “rogue communication devices not listed in product documents ha[d] been found in some Chinese solar power inverters by US experts”. The newswire added that it “was unable to determine how many solar power inverters and batteries they have looked at”. Following this, the Japanese government also “launched an investigation into Chinese-made solar panels”, reported SCMP. Tom Nunlist, associate director at consultancy firm Trivium China, wrote on LinkedIn that while “an industrial-scale plot to disrupt the US power grid” cannot be ruled out, it is “far more likely that we’re dealing with commonplace bill of materials errors”. He added that “given the atmosphere, I think there’s a good chance this will get blown way out of proportion”. Meanwhile, the industry association SolarPower Europe called for stronger cybersecurity rules for Europe’s clean-energy installations, following the discovery of “unexplained electronic components in imported circuit boards from an unnamed country destined for [Denmark’s] energy infrastructure”, PV Magazine said. It added that the “suspicious elements were not solar components”.

Extreme weather sweeping across China

RAIN AND FLOODING: Four people were killed by “torrential rain” in Guizhou province in southwest China and 17 people remained missing, reported Reuters on 23 May. China is facing “hotter and longer heatwaves and more frequent and unpredictable heavy rain as a result of climate change” and its “huge population” made the country “especially vulnerable to the effects of climate change, authorities have said”, added the outlet.

EXTREME HEAT: Temperatures in north China reached as high as 43C in May, according to China Qixiang Aihaozhe, a popular scientific blog. State broadcaster CGTN reported that many places in the provinces of Henan and Hebei broke local temperature records for May and that ground temperatures in “multiple places” broke 70C on 20 May. The outlet noted that May is a “critical” period for maximising wheat harvest yields. Reuters reported that China disbursed 1.4bn yuan ($194m) for “agricultural production disaster prevention and relief”. Meanwhile, cooling demand from air conditioners could drive electricity demand to be about 100GW higher than last year, Bloomberg cited the NEA as saying. Lauri Myllyvirta, lead analyst at CREA, posted on Bluesky that, even if this demand does disrupts the recent plateau in China’s emissions, the “structural trend” of clean-energy additions pushing overall emissions down will continue to drive reductions in the long-term. 


68%

The share of China’s overseas energy investments that went to solar and wind projects between 2022-2023, reported Inside Climate News citing data from Boston University’s Global Development Policy Center. Only 13% of investments had gone into solar and wind from 2000-2021, added the outlet, noting that 2021 was the year that China pledged to stop funding overseas coal projects.


Spotlight 

What is China’s ‘Shenzhen model’ for city-level low-carbon transition? 

Shenzhen, a city bordering Hong Kong that is known for pioneering China’s economic reforms, is leading the country in several carbon mitigation measures and is seen as a “pilot” for the construction of “low-carbon cities”.

Carbon Brief looks back at Shenzhen’s efforts to date and assesses its progress on carbon mitigation. The full article will be available on Carbon Brief’s website.

Electric transportation

Since the 2000s, Shenzhen has developed strategies for “low-carbon development”. Part of this included nourishing the growth of a number of “strategic emerging industries”, such as “new-energy vehicles” (NEVs).

According to a government work report, Shenzhen – whose population makes up 1% of the country’s total – produced 22% of China’s NEVs in 2024. NEV also comprised 77% of the new car sales in Shenzhen last year, significantly higher than the national share of 48%.

The city has also replaced all of its buses, taxis and ride-hailing cars with electric versions – the first city to have done so in China.

Heran Zheng, lecturer in sustainable infrastructure economics and finance at University College London (UCL), told Carbon Brief that a city’s green transition mainly requires two focuses: “transport transition” and “industry decarbonisation”.

With no major heavy industries, Shenzhen has an “advantage” in industry low-carbon transition, said Zheng, which allows it to set “more ambitious” emissions targets.

Carbon control

Shenzhen was China’s “first city to explicitly state its commitment to the ‘dual control [of carbon]’ system”, according to Dialogue Earth. It issued twoimplementation plans” towards this effort and developed a city-level carbon emissions cap.

Shenzhen plans to reduce its energy intensity by 14.5% before the end of 2025, compared to 2020 levels. The national energy intensity target is 13.5% during the same period.

Zheng said that Shenzhen’s commitment “should be within its capacity”, adding:

“There are three major carbon mitigation areas – steel, cement and electricity. Shenzhen has no major steel and cement industries, so it only needs to largely focus on electricity…In addition, the city is a technology hub. A lot of high-emission manufacturers have moved out of Shenzhen to its neighbouring cities.”

Another “big difference” between Shenzhen and other cities is that “Shenzhen has its own nuclear power”, said Zheng, which is “important” for the city’s electricity transition – the remaining sector that Shenzhen needs to put efforts on towards green transition.

Low-carbon energy

According to a 2021 report, nuclear power is Shenzhen’s “largest local power source”. It contributed 35% of the city’s total power generation in 2021.

Nuclear dwarfs all the other clean energy sources feeding into the city’s grid. The Shenzhen local authority’s 2025 government work report says current solar power capacity stands at about 1GW – and it does not mention wind capacity.

Its “14th five-year plan for climate change response” says that Shenzhen’s renewable energy capacity has “little room” for future growth due to “scarce” energy resources and “limited” land for wind and solar power.

In 2024, China approved the construction of more nuclear reactors in Shenzhen’s neighbouring city of Huizhou.

The Shenzhen government also aims to “raise the combined share of natural gas, nuclear and renewable energy to 90% in 2025, up from the current figure of 77%, which is noticeably ahead of the nationwide figure of 52%”, according to research published in 2022.

‘Green finance’

Shenzhen was one of the first seven cities and provinces in China that established a local “pilot” emissions trading system (ETS) in 2013, ahead of the national rollout in 2021.

Yan Qin, carbon analyst at consultancy firm ClearBlue Markets, told Carbon Brief that despite Shenzhen’s plans to expand the coverage of its ETS, most pilot ETSs are seeing their coverage “shrinking” due to enterprises leaving to join the national ETS.

In the meantime, Shenzhen issued China’s first overseas sales of “green government bonds” in 2021 in Hong Kong. In contrast, China’s national sovereign bonds were only available to international buyers from April 2025.

Zheng said that the impact of the green bonds is “hard to evaluate”. He added that projects, such as sewage treatment, can “also fall into the category of ‘green bonds’”. Although linked to energy efficiency improvement, they nonetheless make only “limited contributions” to cutting carbon emissions, he added.

‘Shenzhen model’

The local government and media outlets have touted the city’s achievements on climate as the “Shenzhen model”.

But Shenzhen’s journey is not all “replicable”, said Shen Xinyi, analyst and China team lead at the Centre for Research on Energy and Clean Air (CREA), adding that “Shenzhen capitalised on the opportunities of its era”.

Zheng said Shenzhen can “only represent a [certain] type of city in China, the ‘top tier’, such as Beijing, Shanghai and Guangzhou”. He added:

“There are more than 300 cities in China, all facing unique transition situations. It is meaningless for coal-heavy industrial cities to learn from Shenzhen.”

Other cities must “adapt strategies according to their unique conditions”, Shen added.

CRITICAL MINERALS: An episode of consulting firm Trivium China’s podcast discussed China’s critical mineral export controls.

‘MARSHALL PLAN’?: Sam Geall, Dialogue Earth’s outgoing chief executive officer, published a comment on China’s new role amidst shifting “climate politics”.

US-CHINA DECOUPLING: In an exclusive interview with Chinese financial media Caixin, Huang Hanquan, dean of the Chinese Academy of Macroeconomic Research – a thinktank under the direct management of NDRC – said there are still “risks” in US-China decoupling.

‘ZERO-CARBON’ PARKS: The 21st Century Business Herald, a Chinese media outlet, published an interview with Chai Qimin, director of the International Cooperation Department at the National Center for Climate Change Strategy and International Cooperation, a thinktank under the China’s Ministry of Ecology and Environment, talking about “zero-carbon industrial parks”.

New science 

Peer effects on rural household carbon emissions in China

Scientific Reports

New research found that the “peer effect” – a phenomenon where an individual’s behavior and attitudes are influenced by their peers – has a “significant positive impact” on carbon emissions in rural China. The paper quantified emissions from rural Chinese households over 2012-20 using data from “China family panel studies” and “carbon emission accounts and datasets”. The authors found that carbon emissions from “low social status families” are influenced by those of “high social status families”. They added that the “peer effect has a relatively greater impact on the carbon emissions of farmers in the eastern region”.

The impact of carbon news coverage on corporate green transformation

Scientific Reports

A new study of Chinese companies found that “carbon news coverage significantly enhances the corporate green transformation”. The authors examined the effect of “carbon news coverage” on the green transformation of “Chinese A-share listed enterprises” over 2013-21. They found that “carbon news coverage” can help enterprises with their “green transition” by “alleviating financing constraints, strengthening environmental information disclosure and increasing R&D investment”. They added that “carbon emissions trading market and carbon news coverage serve as multiple co-regulations of formal and informal environmental regulation, synergistically advancing enterprises’ green transformation”.

The 2026 budget test: Will Australia break free from fossil fuels?

Published

on

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

Published

on

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.

    Traditional models still ‘outperform AI’ for extreme weather forecasts

    Published

    on

    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.

    Accuracy of the AI models

This is measured using “root mean square error” (RMSE) – a metric of how accurate a model is, where a lower value indicates lower error and higher accuracy. Source: Zhang et al (2026).

    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.
