In collaboration with the Product Category Rule (PCR) Committee, Michigan auditor NSF International has revised the Concrete PCR to include new life cycle inventory data sources. The revisions inform individual plant or producer, or industry average, environmental product declarations (EPD) for ready mixed and manufactured concrete.
Portland Cement Association recently published new industry average EPDs for Portand Cement and Portland-Limestone Cement through ASTM International. Compared to earlier report data, each declaration demonstrated a significant reduction in carbon impact associated with producing cement in the United States. Each time its specific set of life cycle inventory data sources is revised, the Concrete PCR may warrant updating. New cement data has compelled the National Ready Mixed Concrete Association to revise the Concrete PCR, posted here. Additional information on the Concrete and Cement PCRs can be obtained from NRMCA Vice President, Sustainability Initiatives James Bogdan, 412/420-4138, [email protected].
