NSF/ANSI 140 Standard

Carpet for Business Green Building and The Environment NSF/ANSI 140 Standard

Identifying Sustainable Carpet

Architects, designers and end users seeking environmentally preferred building materials can now identify carpet that has a reduced environmental impact through the American National Standards Institute (ANSI), NSF/ANSI 140 Sustainability Assessment for Carpet.

View a complete list of carpet products certified to the standard.

The carpet industry has made significant progress in reducing the environmental footprint of carpet, including landfill diversion, carbon dioxide emissions, energy consumption, waste generation, water usage and hazardous air pollutants per square yard of carpet. The standard is a means by which these achievements can be quantifiably measured. Further, the standard establishes a pathway towards sustainable carpet by identifying economic, environmental and social benchmarks throughout the supply chain.

NSF/ANSI 140 recognizes sustainable carpet on three performance levels — silver, gold and platinum — using a rating system for performance and quantifiable metrics in the following areas:

  • Public Health and Environment
  • Energy and Energy Efficiency
  • Biobased or Recycled Materials
  • Manufacturing and Reclamation and End of Life Management
