Environmental impacts The environmental cost of copper mining was estimated at 3.7 kg -eq per kg of copper in 2019. Codelco, a major producer in Chile, reported that in 2020 the company emitted 2.8 t -eq per ton (2.8 kg -eq per kg) of fine copper. Greenhouse gas emissions primarily arise from electricity consumed by the company, especially when sourced from fossil fuels, and from engines required for copper extraction and refinement. Companies that mine land often mismanage waste, rendering the area sterile for life. Additionally, nearby rivers and forests are also negatively impacted. The Philippines is an example of a region where land is overexploited by mining companies.
