Our Best for All® strategy provides our customers with profitable steel solutions while creating a more sustainable future for all stakeholders — our customers, investors, employees and communities where we work and live.

This strategy is aligned with our sustainability objectives, as we focus on innovative solutions and industry-leading, low-carbon process technologies.


We are committed to reducing our carbon footprint, and helping our customers reduce theirs, by providing advanced steel products that are manufactured with fewer emissions than traditional steelmaking methods and that can be recycled repeatedly. Our goal is to achieve net-zero greenhouse gas (GHG) emissions (Scope 1 and 2) by 2050.

Disruption in the steel industry is inevitable. We intend to focus on disruptive innovation that is vital to our success, and that advances our sustainability strategy. We are already proving the value of this approach with innovations such as verdeX® and InduX™, infinitely recyclable steels produced from up to 90% scrap while reducing GHG emissions by 70-80%.

We envision a true transformation that goes beyond the steels we make or the manufacturing processes we have used. We will be a steelmaker that is best for our people, our customers, our communities and our planet.


At U. S. Steel, our mission of delivering profitable steel solutions for people and planet underlies everything we do. In 2023, supported by our Board of Directors (Board), we continued our work to fulfill this mission by executing our strategy to deliver the BEST for all our stakeholders.
Our culture is based on our S.T.E.E.L. Principles: Safety First; Trust and Respect; Environmental Stewardship; Excellence and Accountability; and Lawful and Ethical Conduct. We expect our employees and members of our Board to take personal responsibility to “do what’s right,” and our Code of Ethical Business Conduct serves as the foundation for the actions of our employees and directors. To further ensure that employees understand the Company’s expectations and all applicable rules, we provide annual ethics and compliance training to our employees and share communications about key compliance topics, including senior management messages underscoring the importance of doing business with integrity. In addition, through our annual policy certification process, employees of U. S. Steel Košice (USSK) in Košice, Slovakia, non-represented employees in the United States, and members of our Board certify their ongoing compliance with our Code of Ethical Business Conduct.
