Green Steel: What It Is, How It's Made, and Why Buyers Are Paying Attention

Conventional steel production emits 1.8-2.2 tCO2 per tonne, while hydrogen-based direct reduced iron (DRI) can achieve as low as 0.3-0.5 tCO2/tonne, making green steel an increasingly important decarbonization target. Major buyers including automakers, data center developers, and construction firms are purchasing lower-carbon steel due to regulatory pressures like the EU’s Carbon Border Adjustment Mechanism (CBAM) and corporate sustainability commitments. Standardized, facility-level carbon intensity data is essential for comparing steel producers across different production methods and geographies.
