Milei’s controversial glacier reform bill approved by Congress

Lead

Argentina’s lower house of Congress has approved a controversial reform to the nation’s Glacier Law, a move that eases restrictions on mining in periglacial areas and grants provinces greater control over which glaciers are protected. The reform, championed by President Javier Milei, passed early Thursday with 137 votes in favour, 111 against, and three abstentions, after nearly 12 hours of debate. It was previously approved by the Senate in February and will take effect once published in the official gazette.

The amendment modifies the 2010 Glacier Protection Law, which had previously prohibited mining and exploration in glacier and periglacial zones. Under the new framework, the responsibility for designating protected areas shifts from the national scientific body, IANIGLA, to provincial governments. This change is expected to facilitate mining projects for copper, lithium, and silver in the Andes, according to multiple reports.

Coverage Comparison

Reports from Al Jazeera, France 24, and The Guardian emphasized the approval and the ensuing outrage from environmentalists, highlighting protests and the arrest of seven Greenpeace activists who scaled a statue outside Congress. The Buenos Aires Times provided more detailed political context, noting the ruling party’s support from PRO, UCR, and provincial parties, as well as two rebel Peronist lawmakers.

BBC World’s coverage focused on the human stakes, featuring Virginia de Valle, a Mendoza winemaker who fears the reform threatens her vineyard’s water supply. It also noted that Argentina was the first country to pass a law specifically protecting glaciers.

Another Buenos Aires Times article, sourced from Bloomberg, framed the vote as a win for Milei and copper miners, emphasizing the potential US$28 billion in investment for projects like BHP’s Vicuña and Glencore’s El Pachón.

Key Claims

• Vote and Legislative Process: The Chamber of Deputies approved the reform with 137 votes in favour, 111 against, and three abstentions, after nearly 12 hours of debate, as reported by Al Jazeera, France 24, and the Buenos Aires Times. The Senate had already approved it in February.
• Scope of Reform: The reform narrows the definition of protected periglacial environments and allows mining in areas previously off-limits, pending provincial approval. It also updates the national glacier inventory, potentially excluding smaller formations, according to several outlets.
• Shift of Authority: Responsibility for determining which glaciers are “strategic” water reserves moves from IANIGLA to provincial governments, a change supporters say clarifies imprecise criteria and opponents argue will lead to unsustainable exploitation.
• Environmental Concerns: Protesters, including Greenpeace, argue the reforms weaken protections for crucial water sources. Greenpeace Argentina said the change “would put the water security of millions of people at risk.” Activists also warned of the risk to “the water of 70 percent of Argentines,” as quoted by Enrique Viale.
• Supporters’ Position: Proponents, including President Milei and governors from Catamarca, San Juan, Salta, and Mendoza, argue the reform is necessary to attract mining investment and boost the economy. They claim the 2010 law was an unnecessary barrier and that Argentina could triple mining exports by 2030, according to Central Bank estimates.
• Scientific Controversy: Scientists and environmentalists dispute the reform’s basis, with glaciologist Lucas Ruiz calling it based on “false arguments.” IANIGLA director Pablo Villagra said the reform “blurs the role of scientific and technical criteria.”

Perspectives

The reform has drawn starkly different reactions. Supporters, including President Milei and mining industry representatives, see it as essential for unlocking Argentina’s natural resource wealth. Milei stated on social media that the country now has “true environmental federalism” and that “stubborn environmentalists… have once again lost.” Michael Meding of the Los Azules copper project said, “We want legal certainty; we want clear definitions.”

Opponents, including environmental groups and some lawmakers, fear the reform will damage glaciers, which serve as vital freshwater reserves for seven million people across 12 provinces. Greenpeace biologist Agostina Rossi Serra argued that all glaciers act as freshwater reservoirs. Opposition congresswoman Caren Tepp said the law would “no longer [be] a protection but a tool at the service of mega miners.”

Environmental organizations, including FARN and Greenpeace, have announced plans to file a collective lawsuit to declare the reform unconstitutional, calling it a “betrayal” and a “setback.”

Temporal context: The reform passed amid growing global demand for copper and lithium, which are critical for the energy transition. As The Guardian noted, Argentina is a major lithium producer, and miners have argued that the 2010 law prevented them from accessing resources needed for renewable energy technologies. However, glaciologist Lucas Ruiz highlighted the “stark paradox” that mining these minerals could accelerate glacier melt, undermining the very ecosystems that provide water to communities.
