Two New NSF International Programs Help Eliminate Greenwashing

NSFNSF International has begun offering two environmental programs to meet the growing demand for science-based support to verify environmental product claims. NSF can now provide Product Category Rule (PCR) development and Environmental Product Declaration (EPD) verification across multiple product groups and industries.

Based on international environmental management guidelines (ISO 14025), Product Category Rules define how to conduct a life cycle assessment for a particular product group and what to include in the resulting report. A life cycle assessment measures inputs, outputs and environmental impacts of a product across its lifespan, from cradle to grave. The Environmental Product Declaration is the third-party-verified report that functions like a nutrition label to explain the data generated from a life cycle assessment.

Adopted by European countries and growing in recognition in the U.S., PCRs and EPDs provide an international standard of communication to compare and report a product’s environmental impact throughout its entire life cycle. This is a benefit for organizations that manufacture and sell products internationally.

As a leading ANSI-accredited developer of more than 70 American National standards, NSF’s National Center for Sustainability Standards (NCSS), serves as a Program Operator for developing Product Category Rules. The NCSS develops PCRs in a transparent and open process in accordance with internationally-recognized environmental standards.

NSF’s National Center for Sustainability Standards has already begun working with several flooring trade associations on the first North American PCR for resilient, carpet, laminate, tile, and wood flooring products, including:

Carpet and Rug Institute (CRI)

National Wood Flooring Association (NWFA)

North American Laminate Flooring Association (NALFA)

Resilient Floor Covering Institute (RFCI)

Tile Council of North America (TCNA)

Other industries expressing interest in PCRs and EPDs include building products and contract furniture. If your industry is interested in product category rules or environmental product declarations, contact NSF Sustainability Standards Specialist Mindy Costello at
