UL Environment develops ISO 14025-compliant Environmental Product Declarations in five steps.


1. Find an appropriate product category rule (PCR)

  • The first step in creating an EPD is to find or create a PCR that’s applicable to a particular product.

2. Conduct and verify the product lifecycle assessment (LCA)

  • Once an LCA is conducted on a particular product, it must be verified by an independent party to ensure it meets the requirements defined in the product category rules.

3. Compile the EPD

  • The EPD presents the results of the LCA along with additional information about the product’s performance and other sustainability attributes.

4. Verify the EPD

  • An independent, third party conducts a thorough review and verification of the findings presented in the EPD.

5. Register the EPD

  • The EPD program operator adds the EPD to its list of registered EPDs.
