Current EPDs for Wood Products
List of Environmental Product Declarations (EPDs) available for wood products as of March 2026
Environmental Product Declarations (EPDs), sometimes referred to as Type III environmental declarations, report environmental impacts from cradle to gate1 for many construction products, including wood products. They are based on detailed life cycle assessment (LCA) reports and governed by product category rules (PCRs) specific to each product type.
The wood industry was the first to develop transparent, third-party-verified EPDs in partnership with Underwriters Laboratories and in conformance with international standards (ISO 14025, 14040, 14044, and 21930).
North American Structural Wood EPDs
For many years, the American Wood Council (AWC) and Canadian Wood Council (CWC) produced industry average EPDs that covered various North American structural wood products. When many of those EPDs expired in 2025, the organizations decided to move to regional EPDs, in response to industry demand for more granular data. Below is the current list of structural wood product EPDs now available from these two organizations:
- U.S. Inland Northwest softwood lumber
- U.S. Pacific Coast softwood lumber
- U.S. Southern softwood lumber
- U.S. Northern softwood lumber
- U.S. Southern softwood plywood
- U.S. Western softwood plywood
- U.S. oriented strand board (OSB)
- U.S. glued laminated timber (glulam)
- U.S. laminated veneer lumber (LVL)
- U.S. engineered wood I-joists
- North American laminated strand lumber (LSL)
- Regionalized Canadian softwood lumber
- Regionalized Canadian OSB
- Canadian softwood plywood
- Canadian pre-fabricated wood I-joists
- Regionalized Canadian wood trusses
The above EPDs can be downloaded from AWC’s and CWC’s websites. The LCAs that provide the basis for many of these EPDs are available from the Consortium for Research on Renewable Industrial Materials (CORRIM) for U.S. products and Athena Sustainable Materials Institute (ASMI) for Canadian products.
Product-Specific EPDs
The industry average EPDs listed above represent most light-frame wood products available in the U.S. today. In addition, the following EPDs are currently available from WoodWorks manufacturer and supplier partners:
Mass Timber Products:
- Boise Cascade:
- Veneer-laminated timber (VLT) and laminated veneer lumber (LVL): Cradle-to-gate
- VLT and LVL: Cradle-to-grave

1 The production stage of a life cycle, which includes raw material extraction or harvest, transportation of those raw materials to the factory or mill, and manufacturing of the product itself, is often referred to as “cradle-to-gate.” Read more about the life cycle stages here.
