Quantifying the emissions intensity of production at the product level is essential for assessing the environmental profile of high value-added steel products and supporting strategic decarbonization in the industry. A modular and systematic methodology enables CO₂ emissions calculation across Scope 1 and Scope 2 within a closed-loop BF-BOF (blast furnace – basic oxygen furnace) production cycle. The methodology breaks down the production process into individual technological steps, with each step evaluated based on its specific energy, fuel, and material inputs. Emission factors and technological constants are used to quantify both direct and indirect emissions. Consistency and reliability are maintained through real-data validation, energy balance control, and automated correction of deviations. The model allows transparent tracking of emissions per process step and final product, while supporting compliance with environmental reporting standards. The outlined methodology serves as a foundation for adaptable emissions accounting in primary steelmaking environments.
