Real Time Carbon Footprint Tracking Through Enhanced MES to Drive Green Steel Production

Wednesday 19th June 16:15 - 16:45


As part of their own decarbonization process, steel customers are increasingly asking for detailed CO2 footprints of individual products and pieces they buy. For this, correspondingly transparent CO2 tracking and reporting during steel production is necessary and will become the norm. In many industries, reporting CO2 emissions is still high level and often based on yearly production tonnage and related average CO2 equivalents for different processes and plant areas. This paper will highlight a Product Carbon Footprint (PCF) approach implemented as part of the quality management within a steel manufacturing execution system based on process snapshots from all production steps. It introduces hierarchically defined CO2 equivalent emission factors on levels of production area, production line and production step. Thus, all relevant CO2 equivalent emissionscan be calculated and tracked in real time on piece and product level along the entire chain of steel production steps. The results are stored on the related nodes of the material genealogy. Furthermore, PCF tracking and forecasting provide essential input foroptimized production planning, scheduling, and execution with a weighted trade-off between economic and ecological KPIs.Finally, products with labels from certified PCF tracking methodologies allow establishing green lead markets, fostering anincrease in demands for green steel with improved accountability, transparency and trust from investors, government and final customers.
