NSC 373 Sustainable Production of Natural Dimension Stone
The Natural Stone Sustainability Standard
Our current primary initiative is promoting this ANSI sustainability standard and educating the design community about how to apply it to achieve their green building objectives.
What Makes Stone Sustainable?
The NSC 373 Sustainability Standard examines and verifies (through a third party) numerous areas of stone production; effectively improving the baseline for the environmental performance of natural stone. Learn more about what makes natural stone sustainable:

The NSC 373 Sustainability Standard has been established through ANSI, which is administered by the NSF. It is recognized by US Green Building Council (USGBC) with LEED v4 through the Sourcing of Raw Materials credit. The Living Building Challenge also recognizes the standard in the Material Petal, Responsible Industry.
One of the initiatives of the Natural Stone Council is to promote and monitor the use of the Genuine Stone® brand.
Genuine Stone® is defined as stone which has been harvested from its in situ position within the earth’s crust and fabricated without altering the natural fabric of the material. This includes, but is not limited to: granite, marble, limestone, travertine, slate, quartzite, sandstone, and onyx.
This does NOT include: engineered quartz surfaces, manufactured stone veneer, or other artificial building materials.
Cambria, Lapitec, Silestone, Caesarstone, Dekton, Neolith and other brand names may contain natural materials, but they do not fit our definition of Genuine Stone®.
If your material fits the Genuine Stone® definition, and you are a member of one of our affiliate organizations, you are welcome to use the logo in your marketing collateral.
