NRMCA recently verified a system level Environmental Product Declaration (EPD) program for CalPortland Company. Mix designs from nine plants in its Oregon and Southwest Washington division were verified, demonstrating CalPortland's continued efforts to disclose environmental impacts of ready mixed concrete. The EPD was developed in consultation with and based on a software tool by Athena Sustainable Materials Institute. Athena’s Ready Mixed Concrete EPD Calculator is a web-based tool for instant, custom environmental footprint data on ready mixed concrete products. The software tool integrates LCA impacts with mix design criteria to generate EPDs when desired. The software, underlying life cycle data for each plant and EPD was reviewed and verified by Sustainable Solutions Corporation, a verifier in NRMCA’s EPD program.
Glendora, CA-based CalPortland can generate EPDs on demand using the Athena tool. CalPortland’s EPD public listing can be found here, which also includes other CalPortland verified EPDs for ready mix plants and cement products. To date, the North American ready mixed concrete industry, including material suppliers, have verified almost 60 EPDs with more than 20,000 products/mixes and is the leading material industry that reports environmental impacts.
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.
