Green flat steel meeting 0.8 metric tons CO₂ emissions thresholds commands €100-150 per metric ton premiums, below mill asking prices exceeding €200 per metric ton. The Carbon Border Adjustment Mechanism implementation in 2026 & European Steel & Metals Action Plan aim to accelerate adoption through regulatory frameworks, yet high electricity costs create competitive disadvantages.
