Argentina passes Milei’s Glacier Mining Bill, a key change in President Javier Milei’s environmental and economic policies, which will remove limits on mining operations in the glacier and periglacial regions of the Andes, allowing mining companies access to important minerals, including lithium, copper, and silver. While the government contends that these measures will lead to greater economic opportunity and draw in additional foreign investment, the environmental community is voicing concerns that this will do irreparable harm to these delicate ecosystems and the vital freshwater reserves.

What Does the Glacier Mining Bill Change in Argentina’s Environmental Policy?

• Expanding mining zones: The legislation permits extraction operations within the periglacial zone, which was off-limits under the Glacier Protection Law enacted in 2010. Periglacial zones hold substantial quantities of minerals such as lithium and copper necessary for energy transitions on a global level.
• Change in regulation: This change shifts part of the jurisdiction over the designation of protected glacier territories from scientific institutions on a national level to the regional authorities.
• Scale of glacier resources at risk: According to data from the Argentine Glacier Inventory (2018), there are around 17,000 glaciers and rock glaciers within the country. Hence, Argentina is one of the most glacierized countries in South America after Patagonia.
• Impact on access to clean water: Environmental experts suggest that glaciers provide drinking water sources for up to 70% of Argentinians, especially in arid regions of the Andes.

Why Is the Government Promoting Mining Even with Environmental Concerns?

• GDP growth expectations: Argentina’s central bank predicts that mining exports may increase threefold by 2030 due to lithium demand for EV batteries and renewable energy storage.
• Growing global demand for lithium: The International Energy Agency forecasts that lithium demand may multiply over 40 times by 2040 in clean energy scenarios, putting Argentina, which falls within the “Lithium Triangle,” in an advantageous position.
• Political backing from neighboring regions: Provinces in favor of mining, including Mendoza, San Juan, Catamarca, and Salta, back the legislation, emphasizing the generation of employment and infrastructural development associated with massive mining initiatives.
• Legal clarity on vague terms: Mining executives believe that the amendment addresses ambiguous terminology in the 2010 glacier law, offering “legal certainty” to stakeholders involved in mining projects such as the Los Azules copper mine.

What Are the Ecological and Sociological Impacts of This Legislation?

Environmental organizations claim that mining activity in mountains that contain glaciers and forms of new permafrost carries a degree of irreversibility to the landscape. Glacial arteries produce most of our fresh water supply by moderating flow to rivers for consumption in agriculture and urban centers. Research conducted by the Institute of Snow Research in Argentina has shown that glaciers located in regions with a large mining presence in the northwestern provinces of Argentina have contracted by 17% in the last 10 years; the primary drivers of the decline are climate change.

Argentina passes Milei’s Glacier Mining Bill, which has already prompted reactions from civil society, and thousands of protestors, including Greenpeace, gathered in front of Argentina’s Congress on the day of the vote to hold high-visibility demonstrations. Several high-visibility and high-intensity protests took place in addition to the presence of multiple groups.
