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.

It’s the right thing for the environment.

Certifying to the NSC 373 standard gave us an opportunity to identify changes that reduce our carbon footprint without reducing productivity.  For example, when we completed our chemical inventory for the standard we found that we, along with most stone companies, were using dozens of carcinogenic, mutagenic, and toxic chemicals that were very harmful to our employees.

- Aaron Hicken, Delta Stone Products

It’s the right thing for the stone industry.

The natural stone industry is behind other building products in the green building world.  We desperately need to embrace the NSC 373 Sustainability Standard as an industry in order to better position ourselves and our products.  I believe it is critical that we tell our story through certification so that we can show our competitive advantage over other materials, especially man made imitations.

- Rob Teel, Continental Cut Stone

It’s the right thing for your bottom line.

We have been awarded jobs based on our certification – it is that simple.  Architects & designers have made it clear that they value our certification and that it is a key differentiator for our stone.  They can now use our granite as a qualified material for either their LEED or Living Building Standard applications which has brought us into more important jobs and at a higher level of consideration.

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:

Well Recognized

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.

Genuine Stone®

One of the initiatives of the Natural Stone Council is to promote and monitor the use of the Genuine Stone® brand.

Definition

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®.
