Supporting Our Customers in Sustainability

CMC is well-positioned to capitalize on opportunities to help our customers in construction and infrastructure industries as they focus on meeting the growing demand for sustainable projects.

CMC has a long history of supporting our customers with our variety of steel products that are all produced using EAF technology and recycled scrap material. In addition to our steel products, CMC partners with customers to provide guidance and offer sustainable solutions regardless of the product purchased. For example, Tensar’s geogrid products provide ground reinforcement and stabilization to shorten construction schedules for our customers, leading to lower costs and reduced emissions from fewer trucks required to deliver materials. Our Geopier division is a design-build engineering firm that works with customers to find the most efficient and sustainable ground improvement solutions for their foundation and site challenges.

We publish Environmental Product Declarations (EPDs) in the U.S. and EU that help our customers make informed purchasing decisions by providing data on the environmental performance of our products and their potential impacts on the environment. Our EPDs are verified by independent third parties and are frequently required for public and private projects, and often help customers seeking credit for green building certifications, such as Leadership in Energy and Environmental Design (LEED®) certifications.

CMC publishes EPDs on most of our products and updates them periodically in accordance with applicable standards including ISO 21930, ISO 14025, ISO 14040, ISO 14044 and EN 15804+A2:2019. For CMC’s core steel products, including merchant bar, rebar and wire rod, recent updates of our EPDs have demonstrated improvements in our environmental performance over the past five years, with average reductions of 20% in the global warming potentials (GWP) of these products. For example, our unfabricated rebar saw a reduction in global warming potential of 14% averaged across our US mills.

CMC’s products annually contribute to positive ratings for

hundreds of LEED® eligible projects.

New EPDs for Tensar's Geogrid Products

In 2025, Tensar added nine EPDs to our existing portfolio of products produced in the UK, bringing the total number to 41. The additions strengthened the range of EPDs available for geogrids providing stabilization functions and widened the scope of EPDs to cover products used in asphalt interlayers and high strength basal reinforcement applications.

See chapter 1 in the full report to learn more about which of our products have EPDs.

All of Tensar’s geogrids and geocomposites are primarily manufactured from polypropylene or high-density polyethylene materials that are widely recycled across a growing number of industries. Tensar is committed to supporting the circular economy while meeting product performance requirements.
