An ultimate goal of Environmental Product Declarations (EPDs) is comparability of products. However, that’s impossible without having a common set of rules to use when calculating and reporting product-specific impacts. This is where Product Category Rules (PCRs) come into play.
PCRs help minimize market confusion by streamlining the procedures by which products are evaluated for their environmental impacts, ensuring globally consistent data collection and analysis and consistent reporting in EPDs. Ultimately, EPDs therefore enable a more fair comparison of environmental impacts between similar products.
UL is committed to furthering the consistency and transparency of PCR development processes and works with a variety of global program operators and green building schemes to ensure alignment of PCRs and resulting EPDs.
How PCRs are Developed
PCRs are developed in an open and collaborative manner, much like industry standards. Interested parties and stakeholders may participate in what’s known as an open development process, which allows them to review the draft PCR, ask questions, and share comments electronically. Stakeholders may include material suppliers, manufacturers, trade associations, purchasers, users, consumers, non-governmental organizations, public agencies, LCA practitioners, and certification bodies.
UL Environment, a Program Operator functioning under ISO 14025, maintains all comments and questions received during the development process and then posts PCRs for a public comment period. Then, UL Environment will submit a final version of the PCR to a review panel for approval, and once approved, it is published on UL’s Standards website (http://www.shopulstandards.com/). PCRs expire every three to five years and must be updated to address relevant changes in the industry; however, PCRs are living documents and may be updated within this window, if needed.

Product Category Rules Developed By UL Environment
UL Environment can certify EPDs using existing PCRs created by any Program Operator. When no PCR exists for a product group or particular geography, UL Environment will work with stakeholders to create one, or address regionally specific requirements for PCRs created for another market. Below you will find PCRs and geographic-specific addenda created and published by UL Environment:
