ENVIRONMENTAL
STEWARDSHIP

Environmental stewardship is a core value at U. S. Steel, stemming from the Gary Principles created in the early 1900s and continuing today in our S.T.E.E.L. Principles.

We know we must operate our facilities in an environmentally responsible manner and take steps to protect and preserve our shared natural resources. As a company, U. S. Steel articulates our core value of environmental stewardship through three basic principles that are the responsibility of all our employees and our operations.

Those principles are:

  • Compliance with environmental laws and regulations;
  • Continuous improvement in environmental and resource management; and
  • Continued reduction of emissions through innovation.
With a focus on these principles, U. S. Steel collaborates with organizations and peers to promote sustainable and cost-effective environmental strategies through the development of appropriate air, water, waste and climate-change laws and regulations at the local, state, national, and international levels. We are committed to reducing our emissions in our operations and are implementing innovative best practice solutions to improve our environmental performance and reduce energy consumption.
