Certified, Sustainable Natural Stone

Certification to ANSI/NSC373 provides architects and owners stone sources for their buildings that are 3rd party verified as being produced in an economic, environmental and socially responsible manner. Project teams and consumers can now clearly recognize which natural stones support these important project goals.  Watch video

ANSI/NSC 373 Sustainable Production of Natural Dimension Stone and Natural Stone Council Chain of Custody standards have been developed to document and improve the sustainability profile of natural dimension stone production.

The Chain of Custody Standard establishes the rules by which stone originating from a certified quarry and then processed in a certified processing facility is documented as it passes through the supply chain to its end user.   The goal is to insure that the end user who purchases certified stone for a project actually receives verified, certified stone.

The Guidance for Conformance document provides guidance on how ANSI/NSC373 is to be interpreted and gives examples that best provide evidence of criteria compliance by the quarries and processors seeking certification, as well as for the third party entities who will verify compliance.
