We can tell you our forests are managed sustainably and our wood products are made from sustainable sources, but it's important for us to back up our claim. Forest certification, fiber-sourcing certification and chain-of-custody certification are three ways we demonstrate our commitment to sustainable forest management.

ENCOURAGING CERTIFICATION

Today, only 11 percent of the world's forests are certified, with the vast majority in the Northern Hemisphere. Internationally recognized certification standards provide customers and stakeholders with an objective, third-party determination of whether or not companies are implementing sustainable business practices and making products that come from legal and well-managed sources. We support the use of these standards and the use of independent, third-party audits to verify compliance.

We are the first to admit that forest certification can get complicated, quickly. In the United States and Canada, where we operate, there are multiple forest certification programs in use.

The Sustainable Forestry Initiative® [SFI] program is an independent, non-profit organization dedicated to promoting sustainable forest management. It oversees the standards for the largest forests certification program in North America, with more than 285 million acres certified. We are a strong supporter of SFI and believe it is a consistent, science-based standard that allows us to offer a reliable supply of quality, responsibly sourced products at competitive prices.

The American Tree Farm System is the oldest and largest certification system for small, private landowners in the United States. Family forest landowners own nearly one-third of U.S. forestlands and are a critical link in the wood fiber supply chain. We are committed to supporting these landowners and encouraging more landowners to join the program.



The Programme for the Endorsement of Forest Certification is a global umbrella organization that evaluates and recognizes forest certification systems demonstrating compliance with PEFC principles. With more than 741 million acres of certified forests, PEFC endorses nearly 38 sustainable forest management standards worldwide.

Forest Stewardship Council International™ sets national and regional standards for multiple independent certifiers throughout the world. FSCTM International has approximately 470 million certified acres worldwide, with 35 million acres in the United States. FSC International recognizes other FSC standards but is not recognized by PEFC.

We believe having multiple certification systems is advantageous because:

  • It encourages greater use of responsible forest management worldwide, across all types of forest ownerships. 
  • Different programs accommodate different situations, resources and needs of different forest managers (e.g., government, industrial, family). 
  • Manufacturers and their customers have greater flexibility in meeting consumer demands. 
  • Competition encourages all programs to continually improve over time.

LIVING OUR VALUES

America's first certified tree farm

In 1941, 120,000 acres of timberlands owned by the Weyerhaeuser Timber Company in southwest Washington was established as the nation's first certified tree farm under the American Tree Farm System.

The Clemons Tree Farm launched a nationwide program to help private landowners practice forest management on a sustainable basis.
