Types of EPD
While an EPD is for disclosure-purposes only, who prepares it carries a weight in obtaining sustainability credibility by providing validated supporting documentation towards credits with systems like LEEDv4, WELL and other sustainability-driven certifications. They can be self-declared, or certified by a 3rd-party. Clearly, having the EPD created by someone other than the manufacturer carries more weight.
EPD Level I
- From the raw material extraction and processing until the end of the manufacturing process
EPD Level II
- Cradle-to-Gate with Options
- Like Level I, and adds other optional information for the end of life stage such as impacts during demolition and waste disposal stages
EPD Level III
- 3rd party-created
- Complete life-cycle of the product, including installation into the building, maintenance, replacement, and end of life stages
Prepare an EPD Level III and counsel the manufacturer about offensive ingredients that need to be modified in order to pass certification. Once the ingredients are replaced, update the EPD.
