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”.
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.

New summit in Colombia seeks to revive stalled UN talks on fossil fuel transition
A landmark conference hosted by Colombia and the Netherlands will aim to lay the foundations for renewed talks on transitioning away from fossil fuels at COP31, though organisers say it remains unclear what concrete outcomes it will deliver.
The First Conference on the Transition Away from Fossil Fuels will take place in April in the city of Santa Marta, on Colombia’s Caribbean coast, where first-moving countries, states and cities will seek to restart last year’s stalled push for a global roadmap away from coal, oil and gas.
Bastiaan Hassing, head of international climate policy for the Dutch government, told an online briefing last week that the “most obvious” impact of the conference would be for its hosts to report back to the UN climate summit on what was agreed in Santa Marta.
“Ideally, but this is also more complicated, we discuss with each other (at COP) what next steps we could take in the implementation, for instance, of paragraph 28 of the COP decision in Dubai, which talks about the global transition away from fossil fuels,” Hassings said.
He noted that there are many options for how the conference can influence UN talks on implementing the global transition away from fossil fuels, but the exact possibilities would depend on the outcome of the talks. “Rest assured that we will be looking into this,” he added.
At last year’s COP30, a bloc of 80 countries, including small island states, as well as some Latin American, European, and African countries, called for the creation of a roadmap to transition away from fossil fuels.
But major oil and gas producers and consumers blocked the initiative in Belém. As a compromise, Brazil’s COP presidency promised to draft proposals for two voluntary roadmaps: one to end deforestation and another to guide the transition away from fossil fuels.
Brazil has launched consultations seeking input for those plans, asking governments and stakeholders about technological and economic barriers, climate justice considerations and examples of best practice. Last week, COP30 president André Corrêa do Lago told Brazilian media that he would hold discussions on his roadmap proposal at the Santa Marta conference.
Colombia’s environment minister Irene Vélez Torres told reporters last week that “this is the moment to be honest about the challenges involved in transitioning away from fossil fuels”.
“It is not easy. It involves commitments from both the Global North and South. It involves interests and tensions at the subnational level,” she added. “Yet none of this diminishes its urgency or the need to reach agreements at the international multilateral level”.
Process to end fossil fuels
Vélez Torres said she hoped the Santa Marta meeting would help establish an ongoing process to advance discussions that often stall in the formal UN negotiations, where decisions are made by consensus and fossil fuel producers resist stronger language.
“This is the first conference, and we want it to be followed by another. We also want to establish a technical secretariat to sustain these debates,” said Vélez Torres, who added that the initiative would be “articulated with [the] COP30 and COP31” presidencies.
Colombia has been one of the few fossil fuel-producing countries that pledged to halt all new coal, oil and gas exploration. The move triggered backlash from industry and political opponents – with former president Iván Duque calling the decision “political and economic suicide”. The South American country depends on fossil fuels for about 10% of fiscal revenues and 4% of GDP, according to the International Monetary Fund (IMF).
Organisers of the Santa Marta conference said they expect between 40 and 80 high-level representatives from governments, both at national and subnational levels. Colombian president Gustavo Petro is expected to participate, and invitations have been extended to California governor Gavin Newsom and Dutch prime minister Rob Jetten.

No turning back
The conference comes amid renewed volatility in global energy markets. As the US and Israel’s war in Iran disrupts oil and gas supplies and threatens to cause severe global economic damage, analysts say governments should seek to reduce their dependency on fossil fuels through investments in renewables and energy efficiency.
The upcoming Santa Marta conference should build momentum to plan that transition away from fossil fuels and signal that “there is no turning back”, said Peter Newell, professor of international relations at the University of Sussex and one of the main proponents of a fossil fuel non-proliferation treaty.
“Its outcomes, which might include a declaration on key principles and next steps (for the fossil fuel transition), should give renewed vigour to efforts within the UN climate negotiations to drive the agenda forward,” Newell said.
Because major fossil fuel producers have effectively “vetoed” discussions on a fossil fuel phase-out at COPs, he added, willing countries must move forward independently with initiatives like the Santa Marta conference.
Andreas Sieber, head of political strategy at the NGO 350.org, agreed that the push away from fossil fuels is “both necessary and economically inevitable”, adding that a conference on phasing out fossil fuels would have been “unthinkable just five years ago”.
Countries moving forward
COP30 host Brazil has taken the lead in developing its own national roadmap away from fossil fuels, which President Luiz Inácio Lula da Silva requested his government to draft late last year. The roadmap is expected to be formally developed this year.
The plan – expected to include a dedicated energy transition fund – was initially due in February but has not yet been made public as ministers continue technical discussions.
In Europe, governments have also stepped up efforts to curb fossil fuel use following the energy shocks triggered by Russia’s invasion of Ukraine and the conflict in the Middle East.
Leo Roberts, a fossil fuel transition analyst at the climate think tank E3G, said the recent surge in gas prices linked to the Iran conflict reinforces the case for accelerating the transition to boost energy security and protect people from price shocks.
“Hopefully, Santa Marta is able to really demonstrate that not only is there momentum at the international sphere through the COP30 roadmap process, but there’s huge momentum away from fossil fuels in the real world,” he said.

The US’s critical minerals club threatens an equitable clean energy transition
Nick Dearden is the director of Global Justice Now.
The US push for nations to join a club that would coordinate the trade of critical minerals outside China signals a giant shift in Washington’s vision for how to govern the global economy But it will, unfortunately, also hinder the clean energy transition.
Critical minerals such as lithium, nickel, copper and rare earths are needed to manufacture clean energy technologies such as solar panels, wind turbines and batteries on which the transition from fossil fuels to clean energy depends.
But these minerals also have applications for a wide range of advanced technologies, not least military equipment and digital infrastructure. In recent years, AI deployment and the build out of data centres have become the primary political justification for mineral extraction.
No US official mentioned clean energy technologies as they promoted the new minerals club in Washington last month. Instead, the trading bloc aims to break China’s dominance over mineral supply chains and ensure US access to the resources it needs for digital and military sectors.
Analysis by Global Justice Now found that almost one in five of the 33 minerals that the UK identified as critical in 2024 are not needed to achieve the International Energy Agency’s decarbonisation pathways. A further 15 play only a very small role and only seven require significant production increases for the clean energy transition.
Prioritise minerals for the energy transition
The urgency of addressing climate change means we must prioritise the use of minerals to rapidly and equitably wean the global economy off coal, oil and gas while reducing resource overconsumption in the Global North. The US approach could make this prioritisation a lot harder.
For Washington, this isn’t about addressing climate change, but America’s ever deepening rivalry with China, a renewable energy superpower. In contrast, Donald Trump has called climate change “a hoax” and overseen unprecedented climate deregulation in favour of fossil fuels.
The minerals trading bloc risks diverting mineral resources towards carbon-intensive military and technology build-up in the US, which is directly at odds with the need to use these resources to manufacture clean energy technologies.
What’s more, for the green transition to be just, fair and equitable, resource-rich governments must be able to refine and add value to their resources, creating jobs and economic development in the process. But Trump’s trading bloc is intended to tell “partner” countries what role they should play in the global mineral supply chains to best serve US interests.
Serving US interests rather than clean energy
Countries with the smallest and least developed economies stand to lose out.
More than a dozen countries have signed bilateral deals with the Trump administration. The terms of the deals appear to get better the richer a country is.
At the poorer end is the deal with DRC – an outright piece of imperialism with one-sided obligations that override the country’s mineral sovereignty by giving the US first dibs on a range of strategic mining sites and the energy needed to power these sites.
‘America needs you’: US seeks trade alliance to break China’s critical mineral dominance
In the middle, Malaysia committed to facilitate American involvement in its mineral sector and refrain from banning or imposing quotas on exports of raw minerals to the US. This risks restricting the development of Malaysia’s refining capacities, making value addition harder.
At the top end is the UK, which has signed a deal that includes a commitment to streamline mineral permitting, but appears more focused on facilitating financial services to members of the trading bloc.
Wherever countries sit in the pecking order, the agreements signed with the US limit governments’ strategic sovereignty over their resources and stifle their ability to create a more sustainable economy which meets people’s needs.
Tools for a way forward
There is some hope, however. Trump’s mineral trading bloc would operate with profoundly different rules than the neoliberal trade deals, which we have become used to.
Some of its components – like price floors and state ownership – have not been seen in trade deals for a long time. In the right hands, these tools could help governments plan, coordinate and prioritise a globally just green transition and break away from the ‘market knows best’ logic which has long locked poorer countries into low-value exports of raw materials.
If governments work together, outside the coercive US trade bloc, to adopt some of these tools and policies, they might be able to draw local benefits from their mineral wealth and build a genuinely fair and equitable trade in transition minerals.

Greenpeace urges governments to defend international law, as evidence suggests breaches by deep sea mining contractors
SYDNEY/FIJI, Monday 9 March 2026 — As the International Seabed Authority (ISA) opens its 31st Session today, Greenpeace International is calling on member states to take firm and swift action if breaches by subsidiaries and subcontractors of The Metals Company (TMC) are established. Evidence compiled and submitted to the ISA’s Secretary General suggests that violations of exploration contracts may have occurred.
Louisa Casson, Campaigner, Greenpeace International, said: “In July, governments at the ISA sent a clear message: rogue companies trying to sidestep international law will face consequences. Turning that promise into action at this meeting is far more important than rushing through a Mining Code designed to appease corporate interests rather than protect the common good. As delegations from around the world gather today, they must unite and confront the US and TMC’s neo-colonial resource grab and make clear that deep sea mining is a reckless gamble humanity cannot afford.”
The ISA launched an inquiry at its last Council meeting in July 2025, in response to TMC USA seeking unilateral deep sea mining licences from the Trump administration. If the US administration unilaterally allows mining of the international seabed, it would be considered in violation of international law.
Greenpeace International has compiled and submitted evidence to the ISA Secretary-General, Leticia Carvalho, to support the ongoing inquiry into deep sea mining contractors. This evidence shows that those supporting these unprecedented rogue efforts to start deep sea mining unilaterally via President Trump could be in breach of their obligations with the ISA.
The analysis focuses on TMC’s subsidiaries — Nauru Ocean Resources Inc (NORI) and Tonga Offshore Mining Ltd (TOML) — as well as Blue Minerals Jamaica (BMJ), a company linked to Dutch-Swiss offshore engineering firm Allseas, one of TMC’s subcontractors and largest shareholders. The information compiled indicates that their activities may violate core contractual obligations under the United Nations Convention on the Law of the Sea (UNCLOS). If these breaches are confirmed, NORI and TOML’s exploration contracts, which expire in July 2026 and January 2027 respectively, the ISA should take action, including considering not renewing the contract.
Letícia Carvalho has recently publicly advocated for governments to finalise a streamlined deep sea mining code this year and has expressed her own concerns with the calls from 40 governments for a moratorium. At a time when rogue actors are attempting to bypass or weaken the international system, establishing rules and regulations that will allow mining to start could mean falling into the trap of international bullies. A Mining Code would legitimise and drive investment into a flagging industry, supporting rogue actor companies like TMC and weakening deterrence against unilateral mining outside the ISA framework.
Casson added: “Rushing to finalise a Mining Code serves the interests of multinational corporations, not the principles of multilateralism. With what we know now, rules to mine the deep sea cannot coexist with ocean protection. Governments are legally obliged to only authorise deep sea mining if it can demonstrably benefit humanity – and that is non-negotiable. As the long list of scientific, environmental and social concerns with this industry keeps growing, what is needed is a clear political signal that the world will not be intimidated into rushing a mining code by unilateral threats and will instead keep moving towards a moratorium on deep sea mining.”
—ENDS—
Key findings from the full briefing:
- Following TMC USA’s application to mine the international seabed unilaterally, NORI and TOML have amended their agreements to provide payments to Nauru and Tonga, respectively, if US-authorised commercial mining goes ahead. This sets up their participation in a financial mechanism predicated on mining in contradiction to UNCLOS.
- NORI and TOML have signed intercompany intellectual property and data-sharing agreements with TMC USA, and the data obtained by NORI and TOML under the ISA exploration contracts has been key to facilitating TMC USA’s application under US national regulations.
- Just a few individuals hold key decision-making roles across the TMC and all relevant subsidiaries, making claims of independent management ungrounded. NORI, TOML, and TMC USA, while legally distinct, are managed as an integrated corporate group with a single, coordinated strategy under the direct control and strategic direction of TMC.
