Forest Certification

Weyerhaeuser supports third-party certification of forestry practices. Our approach relies on two types of standards: one for environmental management systems, the other for specific practices associated with growing and harvesting trees. For the first, we use the internationally accepted standard for environmental management systems known as ISO 14001. For the second, we rely on national standards: the Sustainable Forestry Initiative® and the Canadian Standards Association's sustainable forest management standard.

We invested in this companywide approach to certification to ensure a reliable supply of products from responsible sources, and to protect the company's preferred position with key customers.

Weyerhaeuser supports mutual recognition among credible certification standards to help facilitate the expansion of certification systems worldwide.
