NRMCA Producer member Graniterock has certified Environmental Product Declarations (EPDs) for 150 products it manufactures at its concrete production facilities in the San Francisco and Monterey Bay areas. Developing and certifying (also called verifying) EPDs requires a rigorous process of conducting a life cycle assessment (LCA) of plant operations and product formulation followed by an extensive review by independent LCA professionals using a standard called a Product Category Rule (PCR). Graniterock chose the NRMCA EPD Program to certify its EPDs. It followed the Product Category Rule for Concrete developed by the Carbon Leadership Forum and relevant international standards. Athena Sustainable Materials Institute conducted the LCA and developed the EPDs for Graniterock and NSF International verified the EPDs. As is required by the international standards, the EPDs are published on NRMCA’s Web site.
