Argentina’s Glacier Law Faces Overhaul Amid Push for Mining Investment
Buenos Aires – Argentine lawmakers are preparing to vote on government proposals to weaken a landmark law protecting glaciers, a move that comes days after President Javier Milei’s administration secured a critical minerals supply deal with the United States. The proposed changes aim to facilitate mining activities in and around glacial regions, sparking concerns from environmental scientists and activists.
A Landmark Law Under Threat
Enacted in 2010, Argentina’s glacier law was the first of its kind globally, prohibiting mining and oil drilling on the country’s nearly 17,000 glaciers and surrounding periglacial areas. These areas are crucial water sources for millions of Argentines and the nation’s agricultural sector. While glaciers cover less than 1% of Argentina’s territory, they overlap with significant mineral deposits, particularly copper, a critical mineral increasingly in demand for renewable energy technologies and electric vehicles. Climate Change News reports that the International Energy Agency forecasts a potential 30% copper supply shortage by 2035.
Government Rationale and Proposed Changes
President Milei argues that the current law creates “uncertainties” regarding the extent of periglacial areas and unnecessarily restricts economic activity. The Buenos Aires Herald details that the government’s bill proposes granting provincial governments the authority to define protected areas and decide whether to allow mining within them. This shift aims to offer provinces greater control over their natural resources, aligning with Argentine law that generally grants them management and development rights, though these can be limited by national legislation.
Provincial Support and Economic Incentives
The bill has garnered support from the governments of Catamarca, Jujuy, Salta, Mendoza, and San Juan – provinces rich in minerals like lithium and copper. These provinces believe the law hinders sustainable economic development. Milei has stated that the changes could lead to one million new jobs and unlock significant investment, emphasizing that “environmentalists would prefer people to die of hunger before touching anything.” The government’s broader agenda includes labor, tax, and crime law reforms, alongside the 2026 budget, all under consideration during these extraordinary congressional sessions.
Concerns from Scientists and Environmental Groups
Environmental scientists express concerns that weakening the glacier law prioritizes business interests over vital water safeguards, especially given the impacts of climate change on glacial areas. Guillermo Folguera, an environmental researcher at Argentina’s National Council for Scientific and Technical Research (CONICET), warns of an attempt to downplay the importance of periglacial areas and their role in the ecosystem. Organizations like FARN highlight that at least four large copper projects, previously stalled due to the glacier law, could proceed if the overhaul is approved.
Potential Mining Projects
Among the projects potentially revived are El Pachón and Agua Rica, owned by Glencore, as well as Los Azules and Josemaria in San Juan province. Science.org notes that Glencore has plans to invest $4 billion in Agua Rica and $9.5 billion in El Pachón. Glencore maintains that its Agua Rica project (now called MARA) is not located on a rock glacier and prioritizes water management. GCN reports that the changes seek to set “clear rules” for mining operations.
Political Landscape and Future Outlook
Milei’s La Libertad Avanza party gained seats in the October midterm elections, bolstering his confidence in securing congressional approval for the glacier law proposal. The appointment of José Peluc to head the lower house’s environment commission signals further support for the amendment. Still, opposition lawmakers have condemned the plan, citing potential constitutional violations and non-compliance with the 2018 Escazu Agreement on environmental rights. The outcome of the vote will significantly impact Argentina’s environmental protections and its pursuit of mining investment.
