The reinforced concrete industry supports the transparent reporting of environmental impacts associated with construction materials. Many green building rating systems (LEED V4), standards (ASHRAE 189.1) and green building codes (IgCC) require the submission of Environmental Product Declarations (EPDs) for products delivered to the project site. EPDs are based on life-cycle assessments (LCAs) and provide information on a range of environmental impacts including global warming potential, ozone depletion potential, acidification potential, eutrophication potential and ozone creation potential.

This industry-wide EPD for steel reinforcement covering the product life cycle from cradle to fabricator gate, satisfies the submission requirements for programs such as LEED and Green Globes. It covers fabricated steel rebar produced by CRSI member companies in the United States and applies to the following specifications.

1. ASTM A615/A615M – Standard Specification for Deformed and Plain Carbon-Steel Bars for Concrete Reinforcement, or
2. ASTM A706/A706M – Standard Specification for Deformed and Plain Low‐Alloy Steel Bars for Concrete Reinforcement

Limitations

This EPD is valid only under the following conditions:

1. This EPD may only be used for mill material produced in the United States.
2. For fabricated steel reinforcement, the EPD is valid only when the material is produced by a current CRSI fabricator member sourcing from participating United States mills.
3. Use of this EPD with products incorporating imported steel or steel from non-participating mills may result in non-conservative estimates of environmental impact.

The CRSI industry-wide EPD represents an average environmental profile based on data from CRSI member mills that participated in the study. It is intended for use only by fabricators sourcing from these mills. Stakeholders should avoid applying this EPD to materials from non-participating or unknown sources.

Guidelines for Member Fabricators Applying the CRSI EPD

When submitting this EPD in support of project requirements, member fabricators must:

1. Confirm that reinforcing steel is sourced from covered U.S. mills.
2. Ensure proper use of the industry-average GWP and environmental impact values, avoiding misrepresentation in project documentation.
