中国清洁能源创纪录的增长使该国二氧化碳(CO2)排放量在2024年的后10个月里保持在低于上年同期的水平。
然而,Carbon Brief 基于官方和商业数据进行的新分析显示,2024年1月和2月,中国正处于疫情解封经济反弹的尾声阶段,加之能源需求异常高的增长,2024年全年CO2排放量未能下降。
尽管中国2024年的CO2排放量相比2023年增长了0.8%,但与截至2024年2月前的12个月期间相比,排放量有所减少。
该分析的其他主要调研结果包括:
- 2024年第四季度,中国的CO2排放量同比增长0.6%,原因外界对经济刺激措施的预期推动了工业用煤使用量和石油需求的上升。
- 此外,2024年最后一个季度风能和太阳能发电量低于预期水平,煤电则同比持平,这可能是因为煤电项目获得优先并网。
- 随着大型风能、太阳能和核电项目竞相试图在“十四五”规划期结束前完工,2025年清洁能源发电装机将加速增长。
- 2024年夏季以来,工业用电需求增长放缓,全年第四季度的能源总需求增速也有所下降。
- 这些因素预计将在2025年推动中国的燃煤发电量下降,这将对全球能源市场和排放产生重要影响。
- 然而,如果政府通过刺激政策推动工业需求增长,尤其是房地产市场复苏,可能会改变这一趋势。
最新分析表明,与以往类似,2025年的政策决策将对中国未来几年的排放轨迹产生重大影响,尤其是中国将在2025年同时制定《巴黎协定》下新的国家自主贡献承诺,以及该国的下一个五年规划。
2024年2月以来排放量趋稳
中国在2023年3月正式结束疫情“清零”政策,导致能源需求从3月到2024年2月同比快速增长。
这使得中国在2024年第一季度的CO2排放量增长了3.8%。
2024年3月至12月,排放量趋于稳定。这是由于清洁电力供应的增长满足了全部电力需求增长,与此同时,水泥和钢铁生产的排放量由于建筑材料需求的萎缩而下降。如下图所示。

2024年2月后,石油消费增长也趋于稳定。化工行业的煤炭使用量以及其他工业部门的煤炭和天然气使用量继续增长,抵消了建筑材料行业排放量的下降。
下图显示了2024年后10个月排放平稳期的各影响因素,在有数据情况下按燃料和行业分列。

非化石能源发电量增长在2023年首次创纪录后再创新高,较2023年增加了逾500TWh(太瓦时)。
这一增量超过了德国2023年全年的总发电量。其中,太阳能发电占清洁电力供应增长的一半。
第四季度排放量小幅上升

在第四季度,尽管电力行业的排放量保持稳定,但电力以外的工业排放量出现增长。由于电力行业排放量的减少未能抵消这部分增长,因此总体排放量估计同比增加0.6%。
中国的CO2排放量在2024年第一季度上升,但自3月起开始下降。在第二季度下降了1%,第三季度趋于稳定。
这其中的主要因素是电力行业以外的石油和天然气需求反弹。下图中“所有行业”和“其他行业”下的长条显示了这一点。
国家统计局初步数据显示,2024年第四季度,天然气和石油需求分别同比增长10%和3%。
同时,成品油供应下降1.5%,因此石油需求的增长显然完全来自化工行业的原油消费。

此外,受2024年9月底出台的刺激政策影响,钢铁产量有所回升。在2024年1月至9月累计下降了4%后,10月至11月增长2%,12月增长12%。
然而,12月的增长主要是因为2023年12月钢铁产量曾骤降15%,这是为了遵守政府设定的当年钢铁产量上限而采取的紧急措施。因此,2024年12月的钢铁产量同比大幅增加,但仍低于2022年水平。
天然气消费量正在从2022年的消费量下降(因当年天然气价格飙升所致)中恢复,但今年的需求增长预计将放缓。
水泥产量在2024年最后一个季度同比下降6%,延续了自2020年开始的下降趋势。由于建筑活动减少,中国的水泥产量已从峰值下降近四分之一。
煤电与清洁能源的冲突
如上图所示,2024年第四季度电力行业的排放量保持平稳,煤炭排放量略有下降,天然气排放量略有上升。然而,鉴于电力需求增速放缓至3.5%,排放量本应下降。
尽管10月至11月电力需求增长放缓,化石燃料发电量却继续增长。通过万德(Wind)金融终端获得的中国电力企业联合会的数据显示,这是由于风能和太阳能发电利用率都急剧下降。
利用率在不同月份有所波动是正常现象,尤其是风电利用率会因风力条件而变化,但这一时期太阳能发电利用率的降幅创下有记录以来的最大值。而无论是太阳能还是风能,此次利用率下降都无法用天气条件充分解释。
如果利用率下降不是由天气原因造成的,那么另一个可能的原因是可再生能源弃电量的增加,即不能被完全并入电网的太阳能和风能电力增加。
然而,官方报告的弃电率仅小幅上升。
11月未报告的风能和太阳能弃电量明显增加,显示出中国电力市场可能会出现的问题,尤其是当对煤电的需求开始下降时。
政府一直在推动电力买家与煤电公司签订保证煤电销量的长期合同。这已经成为一种支撑盈利能力和新煤电产能投资的方式。
然而,这一政策似乎正与清洁能源增长以及减少排放的努力发生冲突。
当清洁能源发电量增长超出预期,或电力总需求增长低于预期时,签订了长期合同的电力买家可能会面临违约处罚,除非他们拒绝清洁能源电力供应,转而购买煤电。
当大量新增煤电装机容量进入市场时,这种冲突会更加突出。这些新机组往往设有内部生产目标,并且至少在某些情况下已提前签订购电协议,因此即使电网没有足够空间,它们也不愿减少出力。
值得注意的是,在2015年前后可再生能源弃电首次成为中国的主要问题,当时煤电需求正在下降。
统计分析还显示,当煤电产能利用率下降时,风能和太阳能利用率往往也会下降——这与预期情况相反。在一个运行良好的市场中,当清洁能源供应增加时,煤电的利用率应当下降。
有统计模型利用每日气象数据预测各省太阳能和风能利用率,但该模型未能预测到2024年10月和11月的利用率下降,这表明天气状况并非主因。
如果2025年电力需求增长放缓,且新增清洁能源装机容量如预期般创下新高(见下),煤电与清洁能源之间的矛盾可能会加剧。煤电需求可能会下降,即使煤炭行业预计仍会快速扩张。
解决这一冲突的唯一可能方式是放宽政府的长期购电合同目标,并接受煤电产能利用率下降。
2024年排放量是否达峰?
我们在一年前的分析中曾预测,中国的碳排放量将在2024年3月由增转降,并持续减少,最终在2024年全年减少2%。
这一预测基于以下三个假设:
- 清洁能源新增装机持续增长;
- 水力发电量恢复至历史平均水平;
- 在2020年至2023年疫情及后疫情时期能源消费异常快增长后,能源消费增速将放缓。
从实际情况来看,清洁能源装机不仅保持增长,而且进一步加速,2024年新增风能和太阳能装机容量有望创下新纪录。水电发电量也有所恢复,但尚未完全恢复到历史平均水平。
下图显示,新增清洁能源装机规模(柱图)足以覆盖新冠疫情前的历史能源需求增长水平(灰色曲线)。
事实上,2024年清洁能源供应的增长远超2015年至2020年间任何一年的能源需求增长。然而,由于高度依赖高耗能产业拉动经济增长,2023年至2024年的能源需求增长高于历史水平,其增速明显快于疫情前的年份,即使在GDP增速放缓的情况依然如此。

具体而言,2024年中国的电力需求增长率为6.8%,而GDP增长率为5%。相比之下,去年的分析假设,在疫情结束及其直接影响消退后,电力需求增长率和GDP增长率将趋同。
这一差异足以推翻对2024年的排放量预测。由于能源需求增长远超预期,即使2024年清洁能源新增装机容量巨大,也只能使排放量保持稳定,而不能使其下降。
这意味着,尽管中国的CO2排放量自3月以来一直平稳,但全年仍可能略有增长,预计增幅约为0.8%,这主要由于1月至2月受疫情后经济反弹影响,排放量快速上升。
因此,根据当前估算,2023年并未成为中国碳达峰之年,因为排放量仍在上升。
从某种角度来看,尽管能源需求增长迅猛,排放量仍能保持稳定已是一项重大成就。但从另一个角度看,若要使全球气候目标仍然有可能实现,中国的排放量必须开始在绝对值上下降。
2025年清洁能源新增装机或将更大
在2023年中国清洁能源装机容量(尤其是太阳能)大幅增长后,即使最乐观的预测也未能预料到2024年会进一步增长。
然而,2024年中国新增太阳能和风能发电装机容量分别同比增长28%和5%,分别有277GW(吉瓦)的太阳能和79GW的风能发电并网。
2025年清洁能源可能再创纪录,因为“十四五”规划(2021-2025年)即将收官,大型太阳能、风能和核电项目将加速完工。国企、地方政府和其他相关主体都在为实现各自设定的目标而努力。
根据TrendForce新能源研究中心的预测,2025年新增太阳能发电装机容量预计将与2024年相当,新增并网容量约265GW。
根据中金公司的预测,2025年新增风电装机将达110至120GW,或刷新纪录,其中海上风电预计将达到14至17GW,较2024年的7GW大幅增长。
在经过两年的低增长期后,中国的核电装机预计将显著增加,从目前的61GW增加到2025年底的65GW。
2024年底,中国新增了约3GW核电装机,其将从2025年开始为非化石能源供应做出贡献。此外,由于2023年和2024年获核准的核电项目数量创历史新高,目前中国共有55GW核电机组已获批或在建,意味着未来五年平均每年将有超过10GW的核电机组投产。
此外,根据全球能源监测(Global Energy Monitor)提供的2024年4月在建水电容量数据,减去去年已投产的容量,截至2024年底,中国仍有至少14GW的常规水电项目在建。
总体来看,2025年可能并入中国电网的新增太阳能、风电、水电和核电装机预计每年可提供超过600TWh的电力,高于2024年新增的500TWh清洁能源发电量。

然而,如上所述,如果新增清洁能源装机能顺利并网且不会出现大规模弃电问题,新增部分才能降低燃煤发电量和CO2排放量。
为了避免该情况发生,中国国家发改委于2025年1月初发布了一项新的电力系统行动计划,目标是在2025至2027年每年新增200GW以上的风能和太阳能消纳利用。
虽然这一目标低于近年来创纪录的新增清洁能源装机容量,但仍表明中央政府支持未来几年有类似的快速增长。
2024年12月,中国最高经济决策者呼吁在中国西部加快建设超大规模的清洁能源“基地”,并提出了创建“零碳工业园区”的新政策。由于工业园区排放的CO2占中国总排放量的30%,这一政策也将推动对清洁能源的进一步投资。
能源需求展望
在未来,中国的排放量是保持稳定,还是达峰后开始下降,仍然取决于新增清洁能源装机与能源需求增长之间的竞赛。
关键问题在于,近期能源需求增长异常迅猛的趋势是否会持续下去,还是会放缓,从而进入一个能源需求增速低于GDP增速的时期。
此前,即2004年和2010年前后,都曾出现类似的能源需求快速增长期,但随后都经历了需求增长放缓的阶段。特别是在2015年前后,能源需求增长明显放缓,中国的排放量也在数年内趋于平稳。
从中国近期的能源需求数据来看,有迹象表明这一模式正在重演。
具体而言,电力需求在2023年和2024年工业大幅上升,但在2024年下半年明显放缓,如下图左上角所示。
服务业和居民用电量的反弹掩盖了这一现象。居民电力需求只是回归至疫情前的趋势线,而服务业电力需求仍低于该趋势线,这反映了疫情对经济结构的长期影响。

近期的能源需求激增,背后是侧重高耗能制造业的经济战略在推动。
由于中国的制造业扩张导致了供应过剩、工业产品价格下跌和利润下降,这一做法可能已达到其极限。
现在,中国政府的目标是通过刺激家庭消费(与制造业相比,家庭消费耗能更低)和“止跌企稳”房地产行业来加快经济增长。
然而,达成这一目标并非易事。2022年的经济工作会议也曾表示,疫情后的经济复苏应由消费主导,但这一愿景并未实现。
2024年的会议减少了对“高质量发展”的着墨,这一概念不鼓励由“低质量”的建设项目所驱动的增长。当局表示要“统筹好提升质量和做大总量的关系”,而2023年当局称“高质量发展”是“硬道理”。
中国能源和排放未来会怎样?
在2024年创纪录的基础上,今年清洁能源的增加将进一步加快。与此同时,工业电力需求的增长自夏季以来已明显放缓。
这两种趋势表明,今年电力行业的排放量可能会下降。然而,政府的刺激措施可能会导致重工业再次出现快速增长,尤其是在建筑业反弹的情况下,这可能会抵消CO2排放量的下降。
如果建筑活动强劲复苏,可能会进一步推动排放增长。煤炭行业看涨,中国煤炭运销协会预计2025年煤炭消费将增长1%。
中国煤炭工业协会预计燃煤和燃气发电量将增长4.5%。该协会认为,扩大投资和稳定房地产市场的刺激政策将导致钢铁、水泥和其他主要耗煤行业的产量增加。
然而,即使政策制定者真的实施了建筑业刺激政策,一个关键问题是其效果有多大、速度有多快。
无论行业协会抱有怎样的希望,迄今为止政府的刺激措施尚未改变市场对钢铁需求下降的预期。
预计实施经济刺激政策的地方政府可能难以大幅增加支出,而且与以往的经济刺激周期相比,对新基础设施的需求要少得多。
如果政府能成功地将低耗能的家庭消费重振为增长来源,那么能源需求的增长就会恢复正常,清洁能源就可以轻松满足所有的增长需求。如果是这样,排放量将开始持续下降。
2025年之后,中国的能源和排放趋势将更加难以确定。例如,尽管最近出现了积极的信号,但今年之后新增清洁能源装机的速度更加不确定。
中国在《巴黎协定》下新的自主贡献承诺预计将在今年发布,其中包含2030年和2035年的目标。此外,涵盖2026至2030年的“十五五规划”将在今年编制,并在2026年初发布。因此,2025年做出的政策决定不仅会在今年,而且会在未来多年对中国的排放轨迹产生重大影响。

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

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

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

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

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

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

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

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