Management model GRI 103-2, 103-3 SDG 11.6

We value responsible action, preventing impacts to the environment and the conscientious use of natural resources. We want to be eco-efficient: that is, to produce more and produce it better, using fewer resources and generating less waste. We seek the best environmental performance possible, whether in our administrative centers, mines or smelters. Our environmental goals are:

75% of recirculation and lower specific use of water;

Reduce the specific emission of greenhouse gases by 5%;

Decrease the disposal of tailings in dams and reduce, by 50%, the specific generation of mining and smelting waste;

Ensure that 100% of the units have prepared a future-use alternative study and an updated decommissioning plan, in line with the sector’s benchmarks.

We use a combined management system based on an Integrated Policy that establishes the guidelines that govern the conduct of the businesses, with a focus on quality management of environmental, health and workplace safety and social responsibility matters. In addition, we strictly respect all environmental laws and regulations pertaining to our business in each country where we operate. SDG 13.2

All of our operating units are ISO 14001 certified and, thus, follow globally recognized systems and compliance standards that support the effort to meet our targets. Annually, each unit undergoes an assessment of compliance with legislation and environmental commitments, conducted by outside specialists. In a two-year cycle, the Unit’s Environmental Management System is audited internally and a self-assessment is conducted each year to identify improvement opportunities. GRI 102-11

Environmental investments SDG 7.A

We invested in diverse programs that address climate change actions to reduce carbon emissions, lower energy consumption and optimize water use. We sought opportunities to be more eco-efficient, betting on innovative projects (see more about Innovation), which led to improvements in equipment and processes and delivered significant environmental gains.

In 2018, investments in the environment totaled US$ 95.1 million, 54.5% higher than in 2017. Of this total, 34% was for waste disposal, 14% went toward effluent treatments and 7% was earmarked for environmental prevention.
