NSF Certification Verifies Sustainability of Stone
December 2, 2013
Calling stone “natural” doesn’t cut it anymore: NSC 373 sets a new standard for quarrying, processing, and transporting dimension stone.Although stone has inherently green properties, its life cycle includes many environmental stumbling blocks (see “ ”). A new NSF International standard developed by the Natural Stone Council (NSC)—NSC 373, Sustainability Assessment for Natural Dimension Stone—aims to distinguish products with a lighter environmental footprint.
The program examines such sustainability indicators as transportation energy (the source of stone’s greatest environmental impact), water use, site management, chemical and waste management, and health and safety.
An NSC chain-of-custody program, reportedly to be published soon, will supplement the new standard by holding a product’s entire distribution network accountable for environmental stewardship as well. “NSC 373 provides a needed standard of excellence in sustainability for the natural stone industry and will serve as the first step of the developing NSC chain-of-custody program,” said NSC executive director Duke Pointer in a press release. The two together “will define and help promote more sustainable products within our industry.”
