We are one of Europe’s main steel manufacturers and a leader in the production of low‑emission circular steel. We produce steel using electric arc furnaces based on the recycling of ferrous scrap — a highly efficient system that minimises the environmental impact of the process.

As Europe’s first producer of steel made from scrap, we operate one of the continent’s largest recycled steel supply chains, consolidating an industrial model built on circularity, efficiency and sustainability.

We give infinite lives to finite resources

Sustainability roadmap

We integrate environmental, social and governance criteria into our management as a means of generating long-term sustainable value.

Our roadmap translates these priorities into action, setting out a clear commitment to decarbonisation, circularity, resource efficiency, people development and the strengthening of a robust governance model aligned with best practice.

Sustainability pillars

Environment

We are making progress with the implementation of our decarbonisation plan, focusing on energy efficiency and the responsible use of resources as key drivers for reducing emissions.

In addition, we are continuing to roll out our climate resilience plan, strengthening our ability to anticipate and adapt to the risks posed by climate change.

This approach is underpinned by an environmental management system geared towards preventing and mitigating impacts, ensuring robust performance in line with the most demanding standards.

We have also strengthened our climate ambition by updating our decarbonisation targets, which have been validated by the Science Based Targets initiative (SBTi), ensuring they are aligned with science and international commitments on climate change.

Circularity

Circularity defines how Celsa optimises resources, reduces its environmental impact and strengthens its industrial model.

Through integrated value chain management, we are moving towards increasingly sustainable and competitive solutions. This approach is reflected in three priority areas: the efficient and resilient management of scrap supply, the recovery of steel mill waste, and the development of products with high standards of circularity.

We use 94% recycled material as raw material and recover 91% of the waste generated. Furthermore, 100% of the steel contained in our products is 100% recyclable, reinforcing the circular nature of our business.

People

We promote a safe, collaborative and development-oriented working environment, where safety, a shared culture and professional growth are key priorities.

We align our values, leadership and communication to foster a shared culture, and we support talent development through training and the acquisition of new skills.

We have a team of 5,097 professionals and are committed to stable, high-quality employment: 92% are on permanent contracts and over 96% work full-time, reflecting a robust model that is committed to people.

Governance

Ethics and transparency, ESG risk management and dialogue with stakeholders form the framework of our governance model.These interrelated areas guide decision-making and ensure management is aligned with the principles of accountability, compliance and good governance.

Through this approach, we strengthen control and oversight mechanisms, anticipate risks and opportunities, and maintain an ongoing dialogue with our stakeholders, integrating their expectations into our strategy and operations.

Contribution to the Sustainable Development Goals

In 2025, we reviewed and updated our double materiality assessment, strengthening the identification and evaluation of the impacts, risks and opportunities associated with sustainability matters across the entire value chain, from sourcing through to the marketing of products and services.We align our contribution to the United Nations Sustainable Development Goals (SDGs) with the results of the double materiality assessment and with our strategic priorities.

This has enabled us to identify and prioritise those goals where we can have the greatest impact. This contribution is reflected in the definition of our own targets in the areas of climate, circularity, safety and governance, which guide our actions and support progress towards a measurable and transformative impact.

Since 2021, we have been a participant in the United Nations Global Compact, committing to the integration of its ten principles in key areas such as labour rights, environmental protection and the fight against corruption.
