Argentina’s Senate passes glacier law reform to unlock mining projects

BUENOS AIRES, Feb 26 (Reuters) – Argentina’s Senate approved on Thursday a reform to the law protecting Andean glaciers, a measure promoted by the libertarian President ​Javier Milei’s government with the aim to ‌unlock investments by mining companies.

The bill, which has been protested by environmental groups, was passed by the Senate with a vote of 40 to 31 as environmental groups protested opposite the Argentina Congress.

The ‌reform ​will now move to the ⁠lower house for a vote.

Mieli’s ⁠bill is part of a broader pledge by his administration to “end arbitrary interpretations” of the glacier law, which the government says has stalled investment and economic ​development.

If enacted, the controversial bill would enable provinces to set their own standards for protecting glaciers and ⁠periglacial environments – high-altitude ice formations, often ⁠covered by rock debris, that serve as ​key freshwater reserves.

Mining companies have argued that the current law, ​which prohibits mining and oil exploration activities from ‌all glaciers identified through a national scientific inventory, requires clearer definitions to enable long-term investment.

“It’s a game changer. It will allow for a clearer understanding of what a ⁠periglacial environment is, and across each province,” said Tomas Lanardonne, an attorney with the firm MHR, which works with energy, ⁠mining, and natural ‌resources businesses.

Environmental groups have pushed back against ⁠the reform, arguing that changes to the ​original ‌glacier law of 2010 will weaken protections ​of water ⁠resources in favor of economic interests.

“To a greater or lesser extent, all Argentines will be affected by the water shortage this will cause in the short term,” said Agostina Rossi Serra of Greenpeace Argentina.
