Sustainability Standards and Protocols
NSF has developed industry-leading standards and protocols for services and service providers, carpet, resilient flooring, textiles, roofing and many more categories.
Standards and Protocols
NSF/ANSI 140: Sustainability Assessment for Carpet
Based on life-cycle assessment principles, the standard employs a point-based system to evaluate commercial carpet products and manufacturers against established prerequisite requirements, performance criteria and quantifiable metrics in six key areas: public health and environment, energy and energy efficiency, biobased or recycled content materials/environmentally preferable materials, manufacturing, reclamation and end-of-life management, and innovation.
NSF/ANSI 332: Sustainability Assessment for Resilient Flooring
This science-based and credible standard establishes a consistent approach to the evaluation and determination of more sustainable resilient floor coverings. Resilient flooring product and manufacturers are evaluated against prerequisite requirements and performance criteria in these key areas: product design, product manufacturing, long-term value, end-of-life management, corporate governance and innovation.
NSF/ANSI 336: Sustainability Assessment for Commercial Furnishings Fabric
NSF/ANSI 336 addresses the environmental, economic and social aspects of furnishing fabric products and manufacturers. This life-cycle, point-based standard includes prerequisite requirements and performance criteria in eight key areas: fiber sourcing, safety of materials, water quality and conservation, energy use, air quality and emissions, recycling practices in manufacturing/end of use and social accountability.
NSF/ANSI 342: Sustainability Assessment for Wallcovering Products
The standard covers materials such as textiles, vinyl, alternative polymer (or vinyl- or alternative polymer-coated), paper and other natural fiber-based wallcovering products. It assigns points by evaluation against prerequisite requirements and performance criteria. Unique to this standard is the requirement to combine points from both the manufacturer and distributor to determine the certification level of a product.
NSF/ANSI 347: Sustainability Assessment for Single Ply Roofing Membranes
NSF/ANSI 347 evaluates single ply roofing membrane products and their manufacturers against prerequisite requirements and performance criteria in five key areas: product design, product manufacturing, membrane durability, corporate governance and innovation. This life-cycle, point-based standard includes criteria across the product life cycle from raw material extraction through manufacturing, use and end-of-life management.
NSF P391: Sustainability Assessment Criteria for Services and Service Providers
This protocol evaluates the environmental, labor and social impact of services, as well as the practices of service provider organizations. A life cycle approach takes into account the inputs to the service provided (such as energy, fuel, packaging, employee training, etc.), the impacts of the service activities (such as transporting employees/materials, etc.) and the outputs associated with providing the service (such as air emissions, waste, GHGs, etc.).
NSF/ANSI 391.1: General Sustainability Assessment Criteria for Professional Services
This standard establishes criteria for evaluating the environmental, social and economic impacts of professional services providers, including organizations classified as professional service providers by the U.S. Federal Professional Services Schedule (PSS) or NAICS Sector 54. Service providers can use NSF/ANSI 391.1 to differentiate themselves from competitors by documenting sustainable business practices, meet state and federal procurement guidelines for sustainable services, and guide their business practices and sustainability programs.
