NRMCA has verified a system level Environmental Product Declaration (EPD) program to help members meet new product transparency credits in green building standards. Martin Marietta is the first concrete producer to verify EPDs using the new system level EPD verification procedure; it has verified 300 products (50 concrete mix designs from six plants) owned and operated by the Rocky Mountain Division. The new program meets international standards for EPD verification, but streamlines the verification process more efficiently, which consisted of reviewing life-cycle assessments (LCA) that were generated from an on-demand EPD software tool developed by Climate Earth. The software tool integrates LCA impacts with mix design batch operating system to generate EPDs when desired. The software and underlying life cycle data for each plant was reviewed and verified by Sustainable Solutions Corporation, a verifier in NRMCA’s EPD program. From this point forward, Martin Marietta can generate EPDs on-demand from each of its six plants using the Climate Earth tool. Martin Marietta EPDs can be found here.

Established in 2012, NRMCA’s EPD Program aims to help concrete producers and concrete product suppliers meet new requirements in green building rating systems such as LEED v4 and other standards, including the International Green Construction Code (IgCC) and the Architecture 2030 Challenge for Products. As the leading Environmental Product Declaration (EPD) Program Operator for the concrete industry, NRMCA has verified over 2,400 mix designs.

As part of the Build with Strength campaign, NRMCA promotes Strength Through Transparency for member and industry competitiveness in the green building marketplace and the trends toward product and company transparency.
