According to U. S. Steel, the declarations provide quantifiable, independent, and audited environmental data about hot-rolled, cold-rolled and corrosion-resistant steels melted at Big River.  

“These enhanced disclosures are valid for five years and equip U. S. Steel customers with objective information about the life cycle impacts and emissions of steel products, enabling them to select more sustainable products for their manufacturing. These (declarations) represent a step forward in the journey to measure our product carbon footprint,” U. S. Steel said in a statement. 

The declarations are certified and audited by the American Society for Testing and Materials, U.S. Steel said.  

Kenneth E. Jaycox, U. S. Steel senior vice president and chief commercial officer, said the declarations will benefit U. S. Steel customers. 

“This development unlocks substantial value to our customers who want to be more informed about their supply chain’s environmental impact,” he said. “Presenting transparent and data-backed validation of our products empowers our customers to make more informed and sustainable decisions.”
