Environmental Product Declarations reaffirm the company’s commitment to sustainability

PITTSBURGH--(BUSINESS WIRE)-- Today, United States Steel Corporation (NYSE: X) (U. S. Steel) announced environmental product declarations (EPDs) across three key offerings including Hot-Rolled, Cold-Rolled and Corrosion-Resistant flat-rolled products where the steel has been melted at Big River Steel Works. The EPDs provide quantifiable, independent, and audited environmental data on these core products. These enhanced disclosures are valid for five years and equip U. S.

These EPDs represent a step forward in the journey to measure our product carbon footprint.

“We are thrilled to have secured EPDs on our three major flat-rolled steel coil products, representing all products melted at Big River Steel Works.
