Argentine lawmakers are set to vote this week on government proposals to weaken a landmark law that bans mining on and around glaciers, days after President Javier Milei’s libertarian administration signed a critical minerals supply deal with the US.
Milei will ask Congress to amend 2010 legislation known as the glaciers law – hailed as the first of its kind in the world – which prohibits activities such as mining or oil drilling on the nearly 17,000 glaciers and surrounding periglacial areas that supply water to millions of Argentines and the vital agricultural sector.
While glaciers account for less than 1% of Argentina’s vast territory, they overlap with large mineral deposits, especially copper, a critical mineral which is in hot demand for use in renewable energy systems, power grid infrastructure and batteries for electric vehicles (EVs).
Soaring demand for the red metal is driving a supply shortage that could reach 30% by 2035, according to the International Energy Agency.
Argentina, already a leading global lithium exporter, does not produce copper at present, but several major projects – on hold for years – could go ahead if Milei’s glacier law overhaul is approved by Congress, environmental campaigners and mining advocates say.
The nation’s mining exports reached $6.04 billion in 2025, according to the government.
Mineral-rich provinces would define protected areas
Milei says his bid to amend the glacier law is a way to give greater autonomy to the provinces by allowing them to decide exactly which glacial areas should be protected and off-limits for mining due to their role in water systems, and which should lose that status. Provincial authorities would then be allowed to grant mining permits in periglacial areas.
The amendment comes as part of a wider push by Milei – a close ideological ally of US President Donald Trump – to draw investment to the country, and the legislative overhaul is backed by mining companies and governors in the nation’s biggest mining provinces such as San Juan, Salta, Jujuy and Mendoza.
“This bill we are sending to Congress will bring investments that could create one million jobs,” Milei said of his plan to overhaul the glaciers law in November, adding that “environmentalists would prefer people to die of hunger before touching anything”.

At ‘Davos of mining’, Saudi Arabia shapes new narrative on minerals
Over 100 countries attended the Future Minerals Forum in Riyadh, putting the Kingdom at the heart of discussions on minerals for the energy transition
Earlier this month, Milei’s administration signed a critical minerals deal with the US to strengthen and secure supply chains, saying the accord was expected to drive significant economic growth and new investment.
But many environmental scientists in Argentina say the government’s proposal puts business interests before safeguards vital to protecting the nation’s water supplies at a time when climate change is taking a heavy toll on glacial areas.
“There is a clear intention among those pushing for these modifications to portray the current protection of the periglacial environment, or glacial waste rock, as a legal exaggeration, minimising the importance of these areas within the glaciers themselves and the ecosystem services they provide,” Guillermo Folguera, an environmental researcher from Argentina’s National Council for Scientific and Technical Research (CONICET), told Climate Home News.
Some mining experts say regulators could protect water supplies by establishing technical criteria – such as the ice content of periglacial areas.
Copper projects on ice – for now
By opening a door to mining on areas that are currently protected, Milei’s plan could clear the way for at least four large copper projects that have been on hold since the glaciers law was passed 15 years ago, said FARN, an Argentine NGO focused on environmental issues and natural resources.
“Today, some projects violate the glaciers law and that, with this regulatory change, could potentially begin operating,” Leandro Gómez, environmental policy coordinator at FARN, told Climate Home News.
Giant copper mining projects that could be revived if the overhaul passes Congress include El Pachón and Agua Rica, both of which are owned by Swiss miner and commodities trader Glencore, according to FARN, which along with 26 other environmental organisations published a document rejecting the government’s proposal.
Last year, Glencore said it planned to spend $4 billion to develop Agua Rica and $9.5 billion to develop El Pachón.
The other two copper projects that FARN says could get the go-ahead if Milei’s amendments are passed are Los Azules and Josemaria in San Juan province.
All four projects are located in areas classified as periglacial zones with rock glaciers, according to surveys by IANIGLIA, the national agency responsible for conducting inventories of such areas.
Asked to comment on its Agua Rica project, now called MARA, Glencore said in a statement the site was not located on a rock glacier.
“There is no rock glacier located in the footprint of the MARA project; neither in any current works nor within the foreseen area of future operations,” it said, adding that water management was a key element of the project’s design.
“We have been developing a system designed to minimise or mitigate impacts on the local communities or the environment,” it said.
Milei is confident of congressional approval
Milei’s La Libertad Avanza party gained ground in Congress following a midterm election in October, and he voiced confidence in January about having enough votes to pass his glacier law proposal.
Last week, José Peluc, a deputy for San Juan from La Libertad Avanza, was designated head of the lower house’s environment commission in a signal of support for the amendment, though some opposition lawmakers have condemned Milei’s plan.
Lawmaker Maximiliano Ferraro from the centrist Civic Coalition told Congress in a recent debate that the proposal “is in clear violation” of the country’s constitution and Latin America’s 2018 Escazu Agreement on environmental rights.
The amendment, like other government measures aimed at boosting big mining projects such as the Large Investment Incentive Regime (RIGI), is supported by the CAEM chamber that groups Argentina’s major mining companies. It has also said the change would help revive deadlocked copper projects.
“Seventy-five percent of the surface area of the copper projects that were announced need clarification of the law because they are in areas considered periglacial,” Roberto Cacciola, CAEM president, told La Nación newspaper.
“Most have already started the application to enter the Large Investment Incentive Regime (RIGI),” he said.
“Irreparable consequences” feared near copper project
In the small town of Andalgalá in Catamarca province, which lies about 17 kilometres from the Agua Rica project, anti-mining activists have been holding weekly marches against the mine’s development since 2010 and they describe heavy-handed police tactics aimed at stifling their protests.
They are dismayed by the government’s attempt to water down the glaciers law, fearing that allowing the mine to operate would endanger the town’s water supplies from the Andalgalá River.
“Starting up Agua Rica would mean large-scale environmental destruction,” said Juan José Cólica, an agricultural engineer who worked for 35 years, until his retirement last year, at the National Institute of Agricultural Technology’s Andalgalá office.

Glencore said it was working to complete the exploitation phase environmental impact report (EIR) for the project, which would be subjected to a technical review by the regulatory authority and public consultation.
“We engage with our host communities to understand and address their concerns, including in respect of economic and social development opportunities for the region,” the company said.
Cólica said allowing the mine to operate at the foot of the snow-capped Aconquija mountain would cause “irreparable consequences that could last for generations”.
“There is no technical method or technology to remedy the damage that could be caused, nor to safeguard the population of Andalgalá from the geological, hydrological, environmental and health risks,” he said.

Argentina’s pioneering glacier law on the line as Milei bets on copper rush
The British government has notified the UN’s Green Climate Fund (GCF) that it will cut the contribution it pledged for 2024-2027 in half, a GCF spokesperson told Climate Home News.
The reduction, which is part of a wider UK shift from development aid to military spending, will restrict the GCF’s ability to fund projects that help developing countries cut emissions and adapt to climate change.
Harjeet Singh, director of the Satat Sampada Climate Foundation, called the UK’s decision “moral bankruptcy”, noting that Britain has a historical responsibility for climate change “as a nation built on fossil-fuelled industrialisation”.

UK cuts support for climate action abroad to fund military instead
The UK’s foreign minister said the cuts to the aid budget would “deliver the biggest increase in defence spending since the Cold War”
Liane Schalatek, who observes GCF board meetings for the Heinrich Böll Foundation, said the UK’s move was “an unfortunate signal”, especially as it comes just before the GCF launches its next fundraising round.
She noted that the UK has been the biggest contributor to the GCF, and “with the UK halving – where doubling would be needed – this will give permission to others to do the same”.
There are fears that other countries could follow suit as governments in Europe trim their aid budgets, while the US has refused to deliver any further money under climate change-sceptic President Donald Trump and has also given up its seat on the GCF board.
The GCF was established in 2010, and has since funded over $15 billion of climate projects across the developing world. Its financing comes mainly from developed countries pledging money in regular replenishment rounds.
During the last GCF replenishment round in 2023, the UK’s previous Conservative government promised £1.622 billion ($2.18 billion) for the 2024-27 period, with then development minister Andrew Mitchell saying the pledge “underlines our sustained commitment to tackling climate change”.
But, as of March 2026, the UK had only handed over £655 million ($885 million) of that pledge, which is its third to the fund, and has now informed the GCF it will only deliver £815 million ($1.1 billion). The GCF’s total funding for the 2024-2027 period is $10.149 billion.
The UK’s Foreign, Commonwealth & Development Office has been contacted for comment.
Approved projects unaffected
A GCF spokesperson told Climate Home News that all current projects under implementation have guaranteed funding while the GCF is assessing what the cuts mean for the projects that are being prepared and are expected to come before the GCF board in 2026 and 2027.
“Our focus will continue to be delivering the greatest impact with the investments we make, working with the largest network of partners in the financial architecture and mobilizing the greatest amount of resources to fulfill GCF’s critical and unique mandate,” the spokesperson said.
Scientists warn El Niño could intensify climate extremes in 2026
In a separate email to GCF board members, seen by Climate Home News, the GCF’s executive director Mafalda Duarte warned that the cuts are “expected to have a material impact” on the fund’s work over the next two years.
Duarte said the cuts were part of the UK wider decision to reduce international development spending “and invest more in addressing growing security threats”.
Development to military
Announcing this decision in March, UK foreign minister Yvette Cooper said the cuts were a “hugely difficult decision” and “not ideological”, but necessary “to deliver the biggest increase in defence spending since the Cold War”. The US has been pressuring countries in the NATO alliance to boost military budgets as conflict surges around the world, from Ukraine to the Middle East.
Cooper reiterated Labour’s commitment to restore overseas development spending to 0.7% of gross national income (GNI) “when fiscal circumstances allow”, but did not provide a timeline when pressed by an opposition member of parliament. UK aid was reduced from 0.7% to 0.5% of GNI by the previous Conservative government in 2021, and is now set to fall further to 0.3%.
While the UK government has claimed it is only cutting international climate finance by around 13% compared to the previous government’s level of spending, analysis by Carbon Brief suggests that the real figure is close to 50% once inflation and accounting changes are considered.
The leadership of the UK is currently in doubt with several ministers from the ruling Labour Party calling on Prime Minister Keir Starmer to resign, with a challenge to his leadership of the party and country expected after poor local election results for Labour.

UK halves Green Climate Fund contribution, as it spends more on security
The Santa Marta summit moved beyond the blockages in the UN climate process, building a coalition of around 60 countries that want to tackle a shift away from fossil fuels. The host countries said the outcomes would feed into the voluntary roadmap on the energy transition being put together by COP30 hosts Brazil, which is due to be presented before COP31.
June’s mid-year climate talks in Bonn, followed by London Climate Action Week, will be key moments to reflect on the progress so far and work out ways to bring the strands closer together. How might that happen while fossil fuels remain the elephant in the UNFCCC room and there’s no formal place for a roadmap on the agenda?
Tune in to hear our expert reporters discussing this and other key topics set to headline at the Bonn session, both in the negotiations and on the sidelines! Questions and comments will be welcome from participants and used to inform our future coverage.

Key developments
New documents ramp up pressure on coal
‘STRICTLY CONTROL’ FOSSIL FUELS: On 22 April, China issued a set of “guiding opinions” on energy conservation and carbon reduction that urged local governments to “strictly control fossil-fuel consumption”, according to the text published by state news agency Xinhua. Hu Min, director and co-founder of the the Beijing-based Institute for Global Decarbonization Progress, said in comments to Carbon Brief that the document was a clear signal of China’s political leaders’ desire to reduce the country’s coal usage and a “way to move things forward” until more specific policies are published. Government officials noted that the opinions are of “great significance for building broader and stronger consensus across society”, reported information platform Tanpaifang.
INCREASED OVERSIGHT: The next day, the government announced new evaluation criteria for judging provinces on their efforts to meet China’s climate goals, including on raising “clean-energy consumption” and limiting “use of coal and oil”, reported Bloomberg. The 14 indicators underscore China’s “key priorities” and encourage broader carbon reduction efforts, said energy news outlet China Energy Net. They build on China’s existing inspection system to create a “much stronger accountability and compliance system”, Qin Qi, China analyst at the Centre for Research on Energy and Clean Air, told Carbon Brief. For more detail see Carbon Brief’s Q&A on what the two policies mean for China’s energy transition.
‘RARE’ SIGNAL: Both documents were issued by the highest levels of the nation’s political system, which is “extremely rare” and “reflects the strategic importance” of China’s climate goals, Wu Hongjie, deputy secretary-general of the China Carbon Neutrality 50 Forum, told Jiemian News. In a comment article for finance news outlet Caixin, Chen Lihao – a member of the Jiusan Society, environment minister Huang’s political party – said the two documents “form the institutional foundation” for China’s “full-scale transition” to a “dual control of carbon” system.
Downpours in south China
‘RECORD-BREAKING’ RAIN: Heavy rainfall is hitting central and southern China, with Hunan, Guizhou and Jiangxi provinces reporting record-breaking levels of precipitation last week, reported the Communist party-affiliated People’s Daily. It added that the government is ramping up “flood control” measures in response. On 26-27 April, one part of Guangxi province received as much as 14cm of rain per hour, reported the state-supporting newspaper Global Times. Meanwhile, Chinese vice-premier Liu Guozhong met with the World Meteorological Organization secretary-general Celeste Saulo to discuss cooperation on global “meteorological governance”, said state news agency Xinhua, with the discussion touching on early warning systems and disaster relief.
EL NIÑO RISK: Officials at China’s National Climate Center (NCC) have said that an El Niño weather pattern is “likely to set in around May” and “intensify during the summer and autumn”, said China Daily. The state-run newspaper also quoted NCC chief forecaster Chen Lijuan saying it was “premature” to conclude that the El Niño could be at its strongest in 140 years, or that it could lead to record-breaking heat, although he added that the risks of such weather are “clearly increasing”. Wang Yaqi, a senior engineer at NCC, noted that the phenomenon “could hit hydropower-dependent regions hard, pushing them to burn more fossil fuels”, according to the Hong Kong-based South China Morning Post.
Solar capacity growth slows
CLEAN CAPACITY: China’s clean-energy grid capacity now exceeds 2,400 gigawatts (GW), as of March 2026, or 60% of the total power mix, said state broadcaster CGTN in coverage of comments from energy officials at a press conference. It added that, within this, total wind and solar capacity reached 1,900GW. Energy news outlet International Energy Net cited the officials saying that China’s operational capacity for “green hydrogen” stands at 250,000 tonnes, with another 900,000 tonnes under construction.
SOLAR SLOWS: However, a data release showed that China added 41GW of new solar capacity in the first three months of 2026, reported BJX News, down from 60GW of new capacity in January-March 2025. Bloomberg noted that new solar capacity additions “slowed sharply to hit a four-year low” in March, adding that wind and thermal capacity growth also both slowed.

‘MOST AMBITIOUS GOAL’: In a separate press conference, Chinese officials confirmed to Bloomberg that a pledge in the 15th five-year plan to double “non-fossil energy” in 10 years referred to energy capacity – not generation or consumption – and would run from 2025-2035. These details were “unclear” in the five-year plan itself, the outlet added. The economic news outlet Economic Daily said that the doubling goal was “one of the most ambitious goals in China’s energy transition history”, adding that “accelerating” the energy transition would allow the country to both reduce its reliance on the international energy market and “seize the high ground in the global race” to develop low-carbon industries.
More China news
- NEW BLEND: China has begun a project to blend gas supplies with 10% hydrogen in a part of Shandong province, reported the South China Morning Post, which added that the shift could cut China’s annual carbon emissions by “roughly 30m tonnes”.
- SKY-HIGH: China launched a “high-precision” satellite to monitor greenhouse gas emissions, said Xinhua.
- SUNNY SPAIN: Chinese automaker SAIC plans to build an electric vehicle (EV) factory in Spain, reported Bloomberg.
- MING YANG: Bloomberg also said that wind turbine maker Ming Yang is considering Spain after plans for a factory in the UK were blocked.
- FORMAL COMPLAINT: China has “formally submitted a complaint” to the EU about its Industrial Accelerator Act, said China Daily.
- EU TARIFFS: China’s commerce minister said he reached a “soft landing” with EU officials on EU tariffs on imports of Chinese-made EVs, according to Reuters.
Spotlight
How war, silver and taxes propelled China’s cleantech exports
China’s export of clean-energy technologies surged in March, driven by a doubling in solar shipments, according to analysis by Carbon Brief of Chinese customs data.
The spike can be explained in part by the impact of the conflict in the Middle East, but analysts argue that a newly enacted solar export policy is also behind the figures.
In this issue, Carbon Brief explores the factors behind the export spike and whether or not it will be sustained.
China’s exports of the “new three” clean-energy technology surged by 70% year-on-year in March 2026, reaching $21.6bn, according to Carbon Brief analysis.
Exports of the three technologies – solar cells and panels, electric vehicles (EVs) and lithium-ion batteries – were also up 37% from February, the month before the Iran war.
The conflict in the Middle East is one explanation for the surge, as it has caused several countries to emphasise the need to increase non-fossil energy supplies.
However, there are also other important drivers, revealed by Carbon Brief analysis of customs data showing differences in exports between solar, EVs and batteries.
Solar exports were notably higher in March 2026 than in the previous two months, jumping 99.2% compared to February.
By contrast, neither batteries’ nor EVs’ March figures came close to the surge in solar cells.
China’s March exports of batteries rose 37% compared with the previous month, while month-on-month EV shipments increased just 1.4%.
(Figures from the China Passenger Car Association suggest a larger rise in percentage terms, but this is based on a narrower scope that does not capture all exports.)
This may be because both technologies saw strong export performance throughout the first quarter of 2026. According to the customs data, more than one million EVs were exported from China between January and March, up 73% compared with the same period last year.
These quarterly exports may have helped meet growing interest in EVs due to the conflict, with BloombergNEF estimating that sales of EVs rose to 1.1m – up 2% year-on-year – in March. (Bloomberg said, within this total, sales “cooled” in China and the US but “surged” in Europe and parts of Asia.)
Solar surge
The chart below shows the export volumes of solar cells, EVs and batteries in March 2025, plus the first three months of 2026.
March’s solar exports were capable of generating 68 gigawatts (GW), equivalent to Spain’s entire installed solar capacity, according to energy thinktank Ember.
The Ember analysis showed that 50 countries set all-time records for Chinese solar imports in March, with another 60 reaching their highest levels in six months.
Exports to Asia doubled to 39GW, while shipments to Africa surged 176% to 10GW. Combined, these two regions accounted for three-quarters of the overall increase in exports.
The Middle East conflict has boosted demand, but a domestic policy deadline was a more immediate driver, analysts told Carbon Brief.
The Chinese government removed export tax rebates for solar products on 1 April, prompting manufacturers to rush out shipments before the change took effect.
Qin Qi, China analyst at the Centre for Research on Energy and Clean Air, told Carbon Brief that such policy deadlines “can create a very sharp one-month jump in shipments”.
Batteries and EVs currently continue to receive export rebates.
Falling silver prices are another potential factor, as silver paste is used to make a key component in solar panels. The reversal of a recent price rally that had raised costs helped manufacturers make more panels ahead of the export switch, Marius Mordal Bakke, head of solar research at consultancy Rystad Energy told Reuters.
Temporary spike
Analysts predict that China’s April solar exports are unlikely to repeat March’s surge. Moreover, February exports were depressed by the Chinese New Year public holiday, making the March comparison unusually unfavourable.
“A month-on-month drop in April would not be surprising,” said Qin.
But she remains optimistic that global solar capacity additions outside China will continue to grow in 2026 due to energy supply concerns sparked by the Middle East conflict.
Dave Jones, chief analyst at Ember, said the removal of the export rebate will not “dramatically change demand”, especially as the conflict continues.
He argued that the policy could be positive, telling Carbon Brief: “This is what the global market needs: a more level playing field with China.”

Watch, read, listen
TARGET ‘DIFFICULTIES’: Two researchers at the Energy Research Institute, a state thinktank, wrote in Economic Daily that China faces several “difficulties” in meeting its new carbon-intensity targets, including already-high renewable capacity installations and high levels of energy efficiency.
COMPARE AND CONTRAST: The US-China Podcast interviewed Prof Alex Wang on China’s approach to environmentalism and his view on the country’s energy transition.
GOVERNMENT CALLOUT: State broadcaster CCTV published a segment critiquing the massive investments and special treatment that local governments gave to their EV industries, fuelling intense competition.
‘THIN ARGUMENT’: A comment in Lawfare argued that the US should focus more on the “genuine geopolitical risks of climate change and [geoengineering] development”, rather than “thin” arguments around China weaponising weather modification technologies.
