Core Insights - The EU's Carbon Border Adjustment Mechanism (CBAM) will fundamentally alter the economic logic of global trade starting January 2026, impacting metal suppliers and buyers by exposing direct and immediate costs related to carbon emissions [1][6] - Carbon intensity will become a core factor determining market access, profit margins, and cost structures, shifting the focus of corporate strategies towards carbon management [1][5] Cost Implications - CBAM will impose carbon costs based on embedded emissions for products like steel, aluminum, cement, fertilizers, electricity, and hydrogen, linked to the EU Emissions Trading System (EUA) prices [7] - As free allowances are phased out, the obligation will increase annually until full implementation in 2034, with EUA prices expected to rise from approximately €70-75 per ton in 2025 to about €130 by 2030 [2][7] - By 2034, carbon costs are projected to represent a significant portion of the import value for most CBAM-covered products, reshaping the cost competition landscape [2][7] Sector-Specific Impacts - The steel industry is expected to bear about 75% of the potential CBAM liabilities, with high-emission steel importers facing additional costs of €40-60 per ton when EUA prices reach €90 in 2026 [3][8] - Aluminum importers may incur burdens close to €500 million in 2026, potentially escalating to €4.7 billion by 2030 if indirect emissions from electricity are included [3][8] Regional Exposure and Trade Risks - CBAM's impact will be concentrated, with over half of the costs expected to arise from major exporting countries like India, Turkey, and Russia, with India alone projected to bear 18% of total CBAM costs [4][9] - This concentration of responsibility indicates a shift in supply chain risks from cost-related to regional and structural risks, necessitating a reevaluation of supply chain strategies [4][9] Strategic Guidance for Enterprises - CBAM represents not just a compliance mechanism but a systematic framework extending the EU's carbon pricing to global trade, making carbon emissions a real cost on financial statements and a decisive variable in business strategies [5][10] - The report "Margins on the line" provides quantitative insights for decision-makers in the metals supply chain, helping to transform regulatory risks into actionable strategies [10]
