About CMC


Sustainability at CMC

Successful companies increasingly understand that the sound corporate governance of both financial and non-financial factors—such as environmental and social issues—benefits their bottom lines. In other words, sustainability issues are business issues, and vice versa. CMC fully embraces this thinking.

Sustainability is and always has been central to what we do. We integrate our sustainability and business strategies as part of our aim to be the first choice for customers and suppliers. Since our first day in operation, we have valued product stewardship and sustainability. We pay close attention to our impact on the world around us, and we look for new ways to strengthen our business while investing in innovations that yield greater efficiencies and environmental benefits.

We pride ourselves on the fact that we’ve had a positive sustainability story from the beginning for over 100 years. Our mills are innovating with the cleanest steel-making methods, and each line of our business plays a role in our sustainability journey.

CMC is also reaching beyond our operations to infuse sustainable activities across the steel industry. In 2023, we became a proud founding member of the Global Steel Climate Council (GSCC).  As such, we believe the global steel industry must play a significant role in global decarbonization efforts and that producers must work towards achieving the goals of the Paris Climate Agreement to limit climate change. GSCC is one step toward getting us there.

We also look to how our products contribute beyond the products themselves. Our Tensar Geogrid product line help decarbonize infrastructure construction projects by reducing the time, energy and materials needed during construction and over the lifecycle of stabilized landforms.
