As the united voice of the stone industry, the Natural Stone Council has been involved in most of the large initiatives within the industry since our establishment in 2003. We lead the charge when it comes to sustainability and research. We also support other associations in their efforts to promote, defend, and improve Genuine Stone® products.
NSC/ANSI 373 Natural Stone Sustainability Standard
The NSC 373 standard examines and verifies (through a third party) numerous areas of stone production; effectivly improving the baseline for the environmental performance of natural stone. Learn More:

Our Natural Stone Sustainability Standard has been established through ANSI, which is administered by the NSF. It is recognized by 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® 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.
If your material fits the Genuine Stone® definition and your organization is a member of one of Natural Stone Council's affiliate's- you are welcome to request permission to use the logo in your marketing collateral.
Benchmark surveys are conducted by the Natural Stone Council every 5 years. These measure how natural stone facilities comply with current regulations. This research is used to make recommendations to MSHA/OSHA boards. We also do our best to let the industry know about new regulations and how to comply.
Research & Results
The NSC is committed to supporting sustainable initiatives and innovations at all levels of the production of Genuine Stone products. Significant work has been accomplished to gather accurate data characterizing the environmental impacts of the natural stone industry in the form of Life Cycle Inventories, Best Practices, Case Studies, and Material Fact Sheets.
In 2014, several misleading articles and claims were made public about the existence of harmful radiation in granite building materials. Several independent companies conducted research that proves conclusively that the amount of radon found occasionally in a slab of granite is not harmful to humans exposed to it.
The Natural Stone Council is constantly looking forward. The landscape of the stone industry is ever changing and we try our best remain a step ahead. A few items that are on our radar include skilled labor shortages, environmental product disclosures (EPDs), and consumer confusion about the term 'natural stone'.
