In 2025, CMOC continued to implement its Environmental Policy, which applies to all operating units across the Group. Aligned with international best practices, the policy reinforces commitments in key areas such as climate change, water resources, biodiversity, waste management, and pollution control, providing clear guidance for environmental management across our operations.

As a mining company with operations spanning extraction, processing, smelting, and associated activities, we recognize that each stage of production carries potential environmental risks. Environmental considerations therefore remain a key focus area, including climate change; energy consumption and greenhouse gas emissions; biodiversity and ecological impacts; tailings; water; air quality; waste management; and mine rehabilitation and closure. We are committed to complying with environmental laws and regulations applicable to our operations. We manage environmental impacts through risk-based management of material issues and adherence to relevant standards. 

We also invest in a range of environmental projects to reduce pollution and mitigate environmental impacts. In 2025, the Company received the highest Wind ESG AAA rating, and was included in S&P Global’s “Sustainability Yearbook (China Edition) 2025” for three consecutive years. In October 2025, the TFM copper-cobalt mine in the DRC successfully passed The Copper Mark’s re-audit, with all areas rated as “fully compliant”.
All of our operations maintain a mature Environmental Management System (EMS) certified to the ISO 14001 standard. These management systems are independently audited at each operating site and include required training of all employees and contractors on environmental objectives and procedures.
