Environmental Product Declarations: EPDs
Capitol Aggregates is proud to be the first cement producer in the United States to publish an EPD for cement.
​
Environmental Product Declarations are independently verified documents that provide transparent and comparable information about the environmental impacts of similar products. This data analyzes the impacts across a product's complete life-cycle: from extraction and manufacturing, through usage and disposal. By examining a product's complete life-cycle, a consumer can truly design a project that has the least environmental impact and highest resiliency.
Capitol Aggregates Cement Environmental Product Declaration
This declaration has been prepared in accordance with ISO 14025 and ISO 21930, the cement category rules and NRMCA EPD Program Operator Instructions. The LCA and EPD was developed and prepared by the Athena Sustainable Materials Institute and independently verified by Sustainable Solutions Corporation. The intent of this document is to further the development of environmentally compatible and more sustainable construction products by providing comprehensive environmental information related to potential impacts of cement available in the USA in accordance with international standards.
Products Covered:
• Type I
• Type III
• ECO-MENT Endure®
• ECO-MENT Spec®
• ECO-MENT® Duropozz®
• Masonry Type N

Concrete’s Contribution to LEED v4
Since its inception, the LEED® green building rating system has been used to reduce the environmental impacts of the built environment. LEED has served as a market-transformation tool affecting all sectors of the construction industry, including concrete production and construction. The system is credit-based, allowing projects to earn points for environmentally responsible strategies implemented during the design and construction process. Due to concrete’s versatility, it can be used in many applications throughout a building project—from foundations and superstructures to sidewalks and parking lots. As a result, concrete can contribute to credits across every LEED category.
Guide to Specifying Concrete for LEED v4
In earlier versions of LEED®, the evaluation of material impacts focused on individual attributes such as recycled content, rapid renewability, or regional sourcing. While these attributes are important, they represent only part of a product’s environmental profile. A material may perform well in one category but poorly in another. LEED v4 Materials and Resources (MR) credits take a more holistic approach by incorporating life cycle assessment (LCA) and product transparency. This document can assist in the preparation of LEED v4 MR submittals for concrete. Other structural materials—such as structural steel, reinforcing bars, masonry, precast concrete, and wood—may follow a similar approach.
