The Natural Stone Institute is a trade association representing every aspect of the natural stone industry. The current membership exceeds 2,000 members in over 50 nations. The association offers a wide array of technical and training resources, professional development opportunities, regulatory advocacy, and networking events. Natural stone is an easy solution to many green building goals. It is nearly complete as a building material in its natural state since mother nature does most of the manufacturing.

The industry-wide EPD is the product group benchmark to which product-specific EPDs can be compared. All life cycle data included in the Sustainable Minds® Transparency Reports [EPD]™ is third-party verified by Ecoform, LLC. SM Transparency Reports provide the technical information required in EPDs and bring that data to life by telling the natural stone sustainability story across the product life cycle.

The Health Product Declaration Collaborative (HPDC) is working with trade associations to assist their members in creating material transparency. The goal of this collaboration is to:
1. Increase participation in material transparency by reducing the friction to participate.
2. Have trade associations offer a multiplication-type effect within an entire industry.

NSI has created example product HPDs for our members to create their own product-specific HPDs.

As a single-ingredient, natural material, that emits no VOCs, natural stone is also a healthy choice for interior spaces. Its inherent durability allows stone to perform impeccably in commercial and residential applications, interior or exterior. Another key sustainable attribute of natural stone is its ability to be refinished and recycled with endless opportunities for reuse after it’s initial service life is complete. Throughout history we’ve seen natural stone used in iconic structures symbolizing strength and permanence. New materials strive to mimic its beauty, but genuine natural materials connect us with our planet and its future in a unique and undeniable way.
