As every year, Eramet was assessed by the Carbon Disclosure Project (CDP), a leading organization in evaluating companies’ environmental impact.

Following the 2025 assessment, Eramet achieved the following scores:

  • A- for water security, a significant improvement compared to the B rating obtained in 2024.
  • A- for climate change, a performance stable compared to 2024.

These results demonstrate the Group’s ability to turn commitments into concrete actions, in line with its Act for Positive Mining roadmap deployed across all its countries of operation.

This recognition places Eramet among the most advanced companies in terms of environmental transparency, within a panel of nearly 20,000 companies assessed worldwide in 2025.

This recognition highlights the consistency of Eramet’s approach to environmental performance as well as the progress of our climate and water-related commitments. As expectations for clear information disclosure continue to grow, data transparency remains a key lever to accelerate action and manage risks for responsible mining and metallurgical activities.

At Eramet, Major Progress in Sustainable Water Management

The significant improvement in the water-related rating reflects in-depth work carried out in recent years across all the Group’s sites:

  • Strengthening data reliability, with a notable improvement in quality and accuracy.
  • Development of water balances for all sites, providing a global and coherent view of consumption and resource dependencies.
  • Progressive alignment of water management plans with major international standards, including the IRMA standard and ICMM guidelines.

This approach helps anticipate water-related risks, optimize usage, and fully integrate these issues into daily operational practices.

CDP: a global benchmark for environmental transparency

The CDP is an international non-profit organization that manages the world’s leading independent system for environmental information disclosure. Each year, it collects and analyzes environmental data provided by companies on a voluntary basis or at the request of financial institutions.

CDP scores have become a key tool for investors. In 2025, more than 640 financial institutions (institutional investors, asset management companies, banks, and insurers) requested data through CDP.

The rating is based on a progressive scale from D- to A, organized into four levels:

  • Disclosure (D / D-): basic transparency on environmental data.
  • Awareness (C / C-): understanding of issues, impacts, and environmental risks.
  • Management (B / B-): implementation of policies, objectives, and structured action plans.
  • Leadership (A- / A): adoption of advanced best practices and demonstration of environmental leadership. Achieving an A- level means the company demonstrates an advanced approach, based on robust data, strong governance, and concrete actions integrated into operations.
