    Climate Change

    CSN is committed to combating climate change and reducing its carbon footprint. While technologies to mitigate these emissions are not yet widely available or economically viable, the Company continues to seek sustainable solutions, aligning its environmental role with economic and social development.

    In 2025, the CSN Group’s second Climate Action Report will be published. It will present advances in the Company’s climate strategy, risk assessment, and progress on its mitigation and adaptation plans. The Guidelines for Climate Governance will also be made available with full transparency.

    Climate Strategy

    The CSN Group’s climate strategy aims to align its businesses with a low-carbon economy, focusing on three pillars: Mitigation, Adaptation, and Stakeholder Engagement.

    Through its Climate Action Plan (CAP), the Company organizes 30 initiatives and approximately 180 actions aimed at reducing environmental impacts and adapting to climate change.

    Under the Mitigation pillar, CSN develops sectoral roadmaps and projects to reduce greenhouse gas (GHG) emissions. This is based on reliable data and a GHG inventory that has been audited since 2014 and has received the Gold Seal since 2021.

    Decarbonization occurs in three phases:

    1. Blue (until 2030): operational efficiency;
    2. Olive (2030–2035): implementation of new technologies;
    3. Green (after 2035): use of disruptive technologies.

    The Company also uses MAC Curves to prioritize projects with the greatest abatement potential and invests in renewable energy to ensure 100% clean electricity in its Brazilian operations. The opening of the free natural gas market in Rio de Janeiro expands decarbonization opportunities at the Usina Presidente Vargas plant.

    CSN’s Stakeholder Engagement pillar seeks to create strategic partnerships that integrate market trends, new technologies, and public policies into the Company’s strategy, ensuring its sustainable evolution.

    CSN promotes transparency with investors, regulators, and society through reports like the Integrated Report and the CDP, disclosing its climate governance and progress in the transition to a low-carbon economy.

    Additionally, CSN engages with clients in sectors like automotive and civil construction to develop products aligned with decarbonization.

    The Company will continue to expand this strategy to meet the sustainability demands of its clients.

     

    Commitments to a low carbon emission

    CSN invests efforts and resources into reducing its greenhouse gas emissions and mitigating the impacts related to climate change. Through the assessment of performance indicators related to greenhouse gas emissions, the CSN Group develops roadmaps to identify new technologies aimed at reducing these emissions and develops decarbonization journeys for its businesses. Given that the steelmaking, cement and mining segments have the most significant impacts, they each have their own decarbonization journeys.

    Steel Industry Reduce CO2e emissions by 10% per ton of crude steel by 2030 and by 20% by 2035, following the premises of the World Steel Association (WSA) methodology.
    Cement Industry Reduce CO2e emissions by 23% per ton of cementitious material by 2030. In this segment, the methodology of the Global Cement and Concrete Association (GCCA) is used.
    Mining Reduce CO2e emissions by 30% per ton of ore produced by 2035 and achieve Net Zero by 2044 for Scopes 1 and 2.

    ESG Engagement

    A CSN believes in the responsible and transparent management of the natural resources with which its operations interact. Annually, one of the ways the Company communicates its practices and environmental performance data to its stakeholders is by reporting to the CDP (Disclosure Insight Action).
