Product Category Rules (PCRs)

A PCR establishes product-specific requirements for the creation of life cycle assessments (LCA) and reporting their findings through Environmental Product Declarations (EPD).

What are product category rules (PCRs)?

PCRs are necessary tools that define the rules and requirements for creating product category specific life cycle assessment studies and summarizing the results in Environmental Product Declarations (EPDs). PCRs are developed in an open and collaborative manner, much like industry standards. Interested parties and stakeholders may participate in 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, nongovernmental organizations, public agencies, life cycle assessment practitioners and certification bodies.

UL Solutions, a program operator functioning in accordance to ISO 14025, maintains all comments and questions received during the development process and then posts PCRs for a public comment period. Then, UL Solutions will submit a final version of the PCR to a review panel for approval. Once approved, it is published on UL Standards website. Most PCRs expire every five years and must be reviewed at that time to address relevant changes in the industry. However, PCRs are living documents and may be updated within this window, if needed.

To move forward with certification of an EPD with UL Solutions, a PCR must already exist for the product type. UL Solutions can certify EPDs using existing PCRs created by any program operator. When no PCR exists for a product group or particular geography, UL Solutions will work with stakeholders to create one or address regionally-specific requirements for existing PCRs that were created for another market.

Below are links to PCRs and geographic-specific addenda created and published by UL Solutions:

PCR – Building related products

The Building Related Products PCR is broken into a Part A core PCR for all building materials, and a Part B, which is product-type specific.   Part A and relevant Part B are to be used together as the full PCR for products within the scope.
