ENVIRONMENTAL STEWARDSHIP
Environmental stewardship is a core value at U. S. Steel. Embedded within our S.T.E.E.L. Principles, caring for the environment is integral to our culture and guides how we conduct our business. Preserving the planet’s future requires responsible management of the natural resources that support healthy communities and resilient ecosystems.
Given the wide range of environmental regulations applicable to our industry, U. S. Steel is subject to extensive compliance obligations across its operations. Accordingly, ensuring strong environmental compliance and fostering constructive relationships with the communities where we operate are top priorities for the U. S. Steel Environmental Affairs team.
Our environmental compliance costs include outlays for testing, sampling, monitoring, inspections and equipment. U. S. Steel spends approximately $100 million annually on environmental compliance. Our environmental expenditures totaled $401 million in 2025, $354 million in 2024, and $345 million in 2023, representing approximately 2% of U. S. Steel’s total costs and expenses for those years.
2025 Environmental Excellence Awards
Our Environmental Excellence Awards program, initiated in 2023, recognizes individuals and teams who demonstrate a strong commitment to environmental stewardship. The program is designed to foster a culture of shared responsibility by encouraging employees across the organization to actively contribute to initiatives that deliver positive environmental impact.
In 2025, across multiple facilities, 12 teams of employees were recognized for leadership and collaboration on projects that strengthened environmental compliance and operational performance. Initiatives focused on improving wastewater and water treatment systems, reducing air emissions, minimizing material losses, and enhancing recycling and slag management practices. Teams implemented new equipment, monitoring systems, and process improvements that reduced costs, improved efficiency, and ensured compliance with evolving regulatory requirements. Collectively, these efforts demonstrate strong commitment to environmental stewardship, continuous improvement, and teamwork across U. S. Steel operations.
