Environmental Stewardship

Why It Matters

We’re certainly not strangers to environmental risks. The effects of climate change—such as extreme weather events and heat waves—may directly impact our ability to operate, making it critical to proactively manage:

  • Greenhouse gas (GHG) emissions
  • Energy
  • Air pollutants
  • Water use
  • Material sourcing
  • Waste generation

Doing so allows us to:

  • Enhance operational efficiency
  • Ensure regulatory compliance
  • Alleviate risks to long-term business success

The GHG emissions avoidance in CMC produced steel vs. the industry average equates to powering 1.8M homes for a full year using renewable electricity.

Our Approach

The drive to innovate and improve keeps us at the forefront of energy and resource efficiency. We implement new operating technologies and approaches to improve resource utilization. By reducing our energy intensity and diversifying our power supplies, we’re actively reducing our climate footprint. We also ensure compliance with environmental laws and regulations across jurisdictions.

While most of our environmentally focused activities take place in our mills—which consume more than 95% of our company’s total energy needs—we continue to address environmental risks across our businesses including our recycling and fabrication facilities, among other operations.

Focus on Sustainable Practices

Amid rapidly changing stakeholder expectations, we must heighten our focus on sustainable business practices. CMC continues to invest in advanced processes and technologies that minimize our environmental footprint and use of natural resources while maximizing performance, reducing business risks and building trust with our customers.
