NSF/ANSI 140 Sustainability Assessment for Carpet is the foremost standard by which to evaluate and certify sustainability of commercial carpet products across their entire product life cycle. NSF’s Sustainable Product Solutions provides certification to the NSF/ANSI 140, Sustainability Assessment for Carpet. This U.S. national standard was developed by NSF through a consensus-based public process by a multi-stakeholder group of manufacturers, suppliers, regulatory agencies, customers, end users, academia and other industry participants. The purpose of this standard is to provide a market-based definition for a path to sustainable carpet, to establish performance requirements for public health and environment and to address the triple bottom line, economic-environmental-social, throughout the supply chain. Based on life-cycle assessment principles, NSF/ANSI 140 employs an easy-to-use point system to evaluate commercial carpet products against established prerequisite requirements, performance criteria and quantifiable metrics in six key areas: Public Health and Environment, Energy and Energy Efficiency, Bio-Based, Recycled Content Materials or Environmentally Preferable Materials, Product Manufacturing, Reclamation and End-of-Life Management and Innovation.
