Founded in 1900, Weyerhaeuser is today one of the world's largest timber, land and forest products companies. We employ thousands of people in businesses that grow, harvest and sell trees and make a range of forest products essential to everyday life.


Our value chain is simple. We start by planting trees, lots of them. We manage our forests sustainably, over many decades, and help others manage their lands equally well. Once harvested, our trees and other wood fiber are made into useful products for society, and we sell our trees to other manufacturing companies that do the same. We are proud managers of a remarkable, renewable resource that, when managed well, can provide jobs, products, renewable energy, recreation and environmental benefits for many generations to come.


Over the last decade, we've planted more than 1 billion seedlings, most of which were grown in our own nurseries. Our tree-planting crews ensure our seedlings are planted correctly and given the best possible chance for survival.


We manage more than 26 million acres of timberlands in the United States, Canada and Uruguay — some of which we own and some of which we manage under long-term government licenses. Read more about our approach to sustainable forestry.

The wood we grow on our own timberlands is sold directly to our wood products and cellulose fibers mills or to customers all over the world. Read about where our logs go in our Annual Report.

We hire qualified logging professionals when harvesting our timberlands and require other forest landowners from whom we buy wood to do the same.


By far, the largest and most critical link in our supply chain is raw wood fiber (in the form of logs and chips), which we convert into wood products and cellulose fibers. We supply our own wood fiber and procure wood fiber from other sources.

Our Wood Procurement Policy ensures we and our sources do not cause or encourage destruction of forest areas at risk of loss from unsustainable practices or illegal logging. We conduct due diligence and document the species and country of origin of our products on our Product Environmental Profiles.

Our commitment to responsible fiber sourcing is verified through our certification to the Sustainable Forestry Initiative® standard. Read more about how we promote sustainable forest management with all of our wood suppliers and more about our certification programs.

At our manufacturing facilities, we produce most of our own energy with biomass residuals, but we still purchase some fuel and electricity to supplement our energy needs. We also rely heavily on transportation and logistics providers to move our raw material and our finished products from our forests to our mills and to our customers. 


We are proud that our company makes useful products for society. Our lumber and engineered wood products are used to construct commercial buildings and homes where people raise their families. Our cellulose fibers are used in diapers and other hygiene products that keep people clean and healthy. And we responsibly deliver the most value from every acre — in some cases, providing recreation access, energy production, conservation and other innovative products from trees.
