Product Category Rule (PCR) Development

  • Overview
  • NSF Developed PCRs
  • Why Work With NSF?

Product category rules (PCRs) allow for review and comparison of different environmental product attributes among products in a defined category.

As an American National Standards Institute (ANSI) eligible program operator, NSF’s National Center for Sustainability Standards can guide industries, trade organizations or individual companies through an ISO 14025-compliant process to develop a PCR for their product categories. We use an open consultative process to develop PCRs with participation from expert stakeholders in product manufacturing, supply chain management, regulatory, environmental consulting, life cycle assessment and other interested parties.
