METLEN has established a comprehensive governance framework for the management of sustainability issues, which is integrated into the Company's core decision-making and oversight processes. The role of the Management is clearly defined and ensures continuous supervision and strategic guidance on sustainability issues.
In particular, the Sustainable Development Committee, as a committee of the Board of Directors, is responsible for monitoring the implementation of the sustainable development strategy, approving relevant policies and monitoring the Company's ESG performance. The Committee meets regularly and collaborates with the General Division of Corporate Governance and Sustainable Development, which plays a crucial role in coordinating all sustainability issues within the Company. The governance of sustainability issues is supported by specially defined organizational structures, which include teams and sustainability officers in each Business Unit and core subsidiary. Those responsible for each ESG thematic pillar work with central and local management teams, ensuring coordination, monitoring of progress and providing technical guidance, with the aim of systematically integrating the principles of sustainable development across the Company's full range of activities.
At the same time, METLEN applies a systematic due diligence approach to manage actual and potential significant impacts, risks and opportunities on sustainability issues. This approach is based on the international guidelines for responsible business conduct and includes: identification and impact assessment procedures, setting targets, action plans, monitoring mechanisms, taking corrective actions, consulting stakeholders and promoting partnerships with the value chain.
Through these mechanisms, METLEN ensures the integration of sustainability considerations into its operational strategy and day-to-day operations, enhancing long-term value creation for all stakeholders.

At the heart of the approach is the active prevention of any identified risk of pollution from the Company's activities, in accordance with the main axes of METLEN's Environmental Policy. The Company fully embraces and integrates the internationally accepted Principles of Responsible Entrepreneurship of the UN Global Compact, within which the protection of the Environment emerges as a special area of commitment.
The Central Environmental Policy forms the framework of the Company's actions to reduce the environmental impact at every level of operation, while the Major Industrial Accident Prevention Policy applied to the primary aluminium production plant, enhances safety with mechanisms to prevent serious incidents that could affect local communities and ecosystems. At the same time, the Code of Conduct for Suppliers and Partners provides specific guidelines for the prevention of any form of pollution, contributing to resilience and transparency throughout the Company's supply chain. The Company fully embraces and integrates the internationally accepted Principles of Responsible Entrepreneurship of the UN Global Compact, within which the protection of the Environment is highlighted as a special area of commitment.
METLEN promotes sustainable development through systematic actions to prevent pollution and manage the environmental impact in all its areas of activity. With an emphasis on technological upgrading and strict adherence to environmental standards, the Company aims to protect the environment and ensure the safety of its facilities.

In the Metals Division, and specifically in the production of alumina and primary aluminum, the Company has set specific targets regarding the management of air pollutants and maintains actions for continuous and documented compliance with the legislative limits, as set by the Environmental Terms Approval Decision (EIA) of the plant.
In the Energy Sector, with regard to the emissions of Power Plants from the combustion of Natural Gas, the targets are monitored through monthly reports. As far as 2025 is concerned, the values of the emissions recorded remained within the prescribed limits, effectively contributing to the achievement of the objectives for the protection of the environment.
In the METKA subsidiary of the construction sector, the state of the environment and the observance of the environmental construction conditions is monitored through the data collected from the construction sites, while at the same time in the Management Systems there is a goal for zero environmental accidents.
In 2025, there were no pollution incidents that degraded soil or water as a result of the productive activity. The Company monitors changes in pollutant emissions over time, analyzing trends and factors that affect them. The measurement of pollutants is carried out using both direct measurements from certified monitoring stations and computer models where required, depending on the nature of the emission and its source. The environmental permits of each facility specify the monitoring points, frequency and methodology, as well as the legal requirements for reporting.
