Sustainability Standards and Protocols
- Why Work With NSF?
NSF Sustainability life-cycle based, multi-attribute sustainability assessment standards and protocols are the benchmarks that define sustainability for products or services in many industries. NSF Sustainability, through the National Center for Sustainability Standards, has developed industry-leading standards and protocols for services and service providers, carpet, resilient flooring, textiles, roofing and many more categories. Learn more about individual NSF Sustainability assessment standards.
For standard development or revision status, visit the NSF Online Workspace.
Get involved with NSF standards and protocol development by joining a Joint Committee. The NSF Standards Department is seeking experts to serve on various NSF joint committees. Learn more.

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. Learn more about NSF/ANSI 140.
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. Learn more about NSF/ANSI 332.
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. Learn more about NSF/ANSI 336.
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. Learn more about NSF/ANSI 342.
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. Learn more about NSF/ANSI 347.
NSF P391: Sustainability Assessment Criteria for Services and Service Providers
This protocol, which is under development as a standard, 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.). Learn more about NSF P391.
Why Work With NSF?
NSF is accredited by the American National Standards Institute (ANSI) to develop American National Standards. Standards development includes stakeholders from industry, non-governmental organizations, government, academia and customers who work together in a consensus-based process. The outcome is standards that provide a sustainability framework for industry.
Sustainability assessment standards and protocols can provide credibility and market acceptance for new products or emerging technologies. Certification to these standards can also provide opportunities for existing products to attract new customers looking for more sustainable products or services.
