Contract-laden GSA calls for concrete, asphalt EPD submittals

Published by Concrete Products: A new U.S. General Services Administration standard targeting low embodied concrete on federal projects will require contractors to provide environmental product declarations (EPD), where available, from ready mixed suppliers.

EPDs express the GHG metric as global warming potential, measured by kilograms of carbon dioxide equivalent per cubic meter. Targets in the General Services Administration’s March 2022 “Low Embodied Carbon Concrete Standards” reflect a 20 percent reduction from the GWP (CO2e) limits the New Buildings Institute proposes in “Lifecycle GHG Impacts in Building Codes” (January 2022).
