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 cooperates with the Directorate-General for 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 organisational structures, which include teams and sustainability officers in each Business Sector and a key subsidiary. ESG thematic pillar managers work with central and local management teams, ensuring coordination, monitoring progress and providing technical guidance, with the aim of systematically integrating the principles of sustainable development across the Company's range of activities.

At the same time, METLEN applies a systematic due diligence approach to manage actual and potential significant sustainability impacts, risks and opportunities. This approach is based on the international guidelines for responsible business conduct and includes: identification and impact assessment processes, setting targets, action plans, monitoring mechanisms, taking corrective actions, consulting stakeholders and promoting value chain partnerships.

Through these mechanisms, METLEN ensures that sustainability issues are integrated into its business strategy and day-to-day operation, enhancing long-term value creation for all stakeholders.
