NSF/ANSI 342: Sustainability Assessment for Wallcovering Products is the foremost standard to evaluate and certify the sustainability of wallcovering products across their entire life cycle. The standard covers materials such as textiles, vinyl, alternative polymer (or vinyl- or alternative polymer-coated), paper and other natural fiber products. NSF/ANSI 342 was developed by the NSF National Center for Sustainability Standards (NCSS) through a consensus-based public process with a multi-stakeholder group. The NSF/ANSI 342 standard assigns point values to prerequisite requirements and elective criteria in a number of categories. Unique to this standard is the requirement to combine points from both the manufacturer and distributor to determine the certification level as Conformant, Silver, Gold or Platinum. Each organization is responsible for its own rating and applies for evaluation individually. Manufacturers are evaluated on categories including: Raw material inputs, Indoor air quality, Product recyclability and Energy use. Distributors must follow environmentally-preferable practices in areas including: Product distribution, Recycling infrastructure support, Waste minimization and Corporate governance.
