EAF Shift Cuts Scope 1+2 by 22%

Challenge

High Scope 1 process emissions from BF-BOF, volatile coke/PCI performance, and fragmented electricity sourcing made it hard to quantify the true impact of route changes and RE procurement.

Approach

• Process telemetry: ingested coke ovens, sinter plant, hot metal chemistry, and EAF meter data.
• Route mix tracking: monthly BF-BOF vs DRI/EAF share with intensity deltas.
• Energy attribution: market-based Scope 2 with PPAs/RECs and residual mix disclosure.
• Controls: factor versioning (Worldsteel/DEFRA), reviewer sign-off, evidence vault.

Results

• 22% reduction in Scope 1+2 intensity YoY; 5% yield improvement coil-out.
• 7-point rise in EAF share; coke & PCI stabilized within control limits.
• Audit-ready exports for BRSR, CSRD (ESRS E1), and Worldsteel methodology.
