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 align our environmental management systems with the internationally accepted standard known as ISO 14001. For the second, we rely on North American based standards: the Sustainable Forestry Initiative® and the Canadian Standards Association's sustainable forest management standard. In Uruguay and China, we will certify to appropriate national standards based on availability and customer need. In addition to certification, all forestlands we own are managed to the requirements of Weyerhaeuser's internal sustainable forestry standard, which ensures a consistently high level of stewardship.

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.
