Environmentally Preferable Product (EPP) Downstream

The Environmentally Preferable Product (EPP) Downstream certification, administered by the Composite Panel Association (CPA), is designed for manufacturers and fabricators who use composite wood panels as inputs in their own products. Companies that earn the EPP Downstream designation have demonstrated their environmental commitment by sourcing at least 50% of their composite wood panel purchases from CPA EPP-certified suppliers — meaning the panels themselves meet the CPA's rigorous environmental standards for composite wood products.

The EPP program is the most widely specified environmental certification for composite wood products in North America, covering markets in the United States, Canada, and Mexico. For downstream users — such as furniture manufacturers, cabinet makers, and building product fabricators — achieving this certification signals to buyers and specifiers that their products are made with environmentally vetted materials.

This program is relevant for construction and manufacturing companies that want to substantiate environmental claims about their finished goods, meet green building specifications, or respond to procurement requirements that prioritize sustainable sourcing. The EPP Downstream logo provides a recognizable, third-party-backed signal that a product's supply chain reflects meaningful environmental standards.
