NSF/ANSI 140: Sustainability Assessment for Carpet is the industry-leading standard for sustainability evaluation and certification of carpet products across their entire life cycle. In fact, the U.S. General Services Administration (GSA) now requires all broadloom and carpet tile purchased by the U.S. government to be certified to NSF /ANSI 140 at the gold certification level.

What is NSF/ANSI 140?

NSF/ANSI 140: Sustainability Assessment for Carpet was developed by the NSF National Center for Sustainability Standards (NCSS) through a consensus-based public process with a multi-stakeholder group of participants. This standard provides a market-based definition and path to more sustainable carpet through performance requirements for the individual product and the manufacturing organization.

Based on life-cycle assessment principles, NSF/ANSI 140 employs a 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
  • Biobased, recycled content materials and environmentally preferable materials
  • Manufacturing
  • Reclamation and end-of-life management
  • Innovation

Benefits of Certification

NSF/ANSI 140 certification allows you to:

  • Distinguish your "green" products from your competitors’, making you a preferred vendor to those seeking sustainable solutions.
  • Meet state and federal procurement guidelines for sustainable products. NSF/ANSI 140 is included in EPA's Recommendations of Specifications, Standards, and Ecolabels for Federal Purchasing.
  • Achieve the most credible type of certification available in the marketplace.
  • Save money by adopting more sustainable operational practices and business approaches.

Certification is based on point totals to achieve a Silver, Gold or Platinum level. Manufacturers certified by NSF are authorized to use the NSF Sustainability Certified mark on their products and in their advertising.
