The National Ready Mixed Concrete Association has certified the inaugural Environmental Product Declaration for cement in North America, covering five grades from Capitol Aggregates’ flagship mill in San Antonio, Texas. The Environmental Product Declaration for Capitol Aggregates, a National Ready Mixed Concrete Association member since 1957, follows a September 2015 milestone when the association certified its 2,000th concrete declaration-by far the most of any building product category.
Developing and certifying Environmental Product Declarations requires material producers to conduct a life cycle assessment of plant operations and product inputs, followed by a review.
The National Ready Mixed Concrete Association Environmental Product Declaration Program follows ASTM International’s Product Category Rule for Portland, Blended Hydraulic, Masonry, Mortar, and Plastic (Stucco) Cements. Consistent with international standards protocol, the Environmental Product Declarations verified by National Ready Mixed Concrete Association are published online at www.nrmca.org/sustainability/Environmental Product Declaration Program.
Established in 2012, National Ready Mixed Concrete Association’s Environmental Product Declaration Program aims to help concrete producers and allied suppliers meet requirement in new green building rating systems, chiefly LEED v4, plus standards accompanying the International Green Construction Code and Architecture 2030 Challenge for Products. Environmental Product Declarations are third-party verified reports suppliers, processors and manufacturers publish to provide quality-assured and comparable information regarding environmental performance of their materials and products.
Architects and engineers request or require Environmental Product Declarations to demonstrate reduction in the environmental impacts of their building projects. Design professionals can objectively compare the environmental impacts of the materials or products they specify against an industry benchmark, or average.
The National Ready Mixed Concrete Association was one of the first industry groups to publish an industry-wide Environmental Product Declaration and industry benchmarks.
