A common misconception is that Environmental Product Declarations (EPDs) are the same as life cycle assessment (LCA) reports. While LCAs are essential components of EPDs, the LCAs used in EPDs must fulfill certain product-specific calculations and requirements known as product category rules (PCRs).

PCRs help minimize market confusion by streamlining the procedures by which products are evaluated for their environmental impacts and ensuring globally consistent data collection and analysis. EPDs therefore allow for the fair comparison of environmental impacts between similar products.

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 consultation 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 will prepare a short summary of all comments and questions received during the open consultation process, along with any edits to the PCR. Then, UL Environment will submit a final version of the PCR to a review panel for approval.

If you are interested in working with UL Environment on the creation of PCRs, email us at:

Request for Information

Stakeholder engagement is an essential component in the development of UL Environment PCRs, and your time and assistance is greatly appreciated.

Product Category Rules Developed By UL Environment

UL Environment can certify EPDs using existing PCRs created by any program operator. When no PCRs exist for a product group, UL Environment will work with stakeholders to create them. Below you will find PCRs created by UL Environment:
