The Environmental Product Declaration
An Environmental Product Declaration (EPD) describes a product’s environmental impact, energy use and efficiency, global warming potential, emissions to air, soil and water, and waste generation. EPD is internationally recognised, serving as a product’s environmental label or declaration.
The information comes from a science-based life cycle assessment (LCA) of a product. For a list of LCA terminology, click here.
EPDs are available for US softwood plywood, OSB, I-joists and LVL , and they all comply with EN 15804, the key environmental standard for determining an Environmental Product Declaration (EPD). These have been produced jointly by the American Wood Council (of which APA is a member) and the Canadian Wood Council. A shortened version, a Transparency Summary, is also available. If you want the shorter version, click here.
Business-to-business (B2B) EPDs for wood products are generally limited to specific stages of the life cycle, such as cradle-to-gate, since manufacturers may not be able to characterise how their product might be used after it is sold. While the requirement for an EPD is not yet included in the CPR, this is planned.
