Case Study: ArcelorMittal Steligence achieves up to 50% embodied carbon reduction with One Click LCA

ArcelorMittal Steligence - Customer Case Study

ArcelorMittal Steligence, the construction engineering arm of the global steel and mining company ArcelorMittal, needed a practical way to support low-carbon building design while balancing cost, speed, flexibility, and material performance. Its teams had to help architects, designers, and project owners make better carbon decisions early in the design process, where the biggest sustainability gains can be achieved. They used One Click LCA to run lifecycle carbon assessments and compare steel-based design options.

With One Click LCA, ArcelorMittal Steligence could quickly and reliably analyze projects, identify CO2 hotspots, test design alternatives, and support EPD interpretation and reporting. The platform’s comprehensive EPD database, easy-to-use interface, BIM link, and strong support helped the team optimize designs and communicate results clearly. By combining low-carbon steel products with intelligent design, ArcelorMittal Steligence says it has achieved up to 50% reductions in building carbon impact, while supporting products such as XCarb® with a published A1-A3 GWP of 333 kg CO2eq/t for sections and merchant bars.
