What is an EPD?

Environmental Product Declarations, or EPDs, rely on Life-Cycle Assessment (LCA) to provide information on a number of environmental impacts of products over their life cycle. EPDs do not indicate that any environmental or social performance benchmarks are met, and there may be impacts that they do not encompass.  EPDs can complement but cannot replace tools and certifications that are designed to address these impacts and/or set performance thresholds – e.g. Type 1 certifications, health assessments and declarations, environmental impact assessments, etc.

EPDs regularly rely on estimations of impacts, and the level of accuracy in estimation of effect differs for any particular product line and reported impact. EPDs are not comparative assertions and are either not comparable or have limited comparability when they cover different life cycle stages, are based on different product category rules or are missing relevant environmental impacts.  EPDs from different programs may not be comparable.

CORRIM has produced and contributed to a number of EPDs in conjunction with the American Wood Council, Canadian Wood Council, and the Composite Panel Association. The declarations listed below are environmental product declarations in accordance with ISO 14040 standards (ISO 2006), ISO 21930 (ISO 2017), the Product Category Rule (PCR) for North American Structural and Architectural Wood Products (UL 2019) that will provide the guidance for preparation of North American wood product Environmental Product Declaration (EPD) and Part A: Life Cycle Assessment Calculations Rules and Report Requirements (UL 2018).
