Plaintiffs challenged the environmental impact assessment for the continuation of a mining project in Cerro Colorado, in the Taparaca Region of Chile. The main claim refers to the lack of due consideration of citizen observations on the mining project's impact on groundwater resources and related surface ecosystems.
The court did not question the methodology for evaluating the impact on water resources, nor did it annul the mitigation measures originally imposed within the evaluation process. Quite the opposite, it considered that these measures were aligned with the relevant norms. However, the Tribunal considered that a proper approach considering the country's international commitments under the UNFCCC and the Paris Agreement also requires the incorporation of climate change scenarios. Thus, it requires re-assessing the mitigation measures regarding the extraction of groundwater water resources in the area in light of current and potential climate change impacts.
