Forest Certification

All of the forests we own or manage worldwide have environmental management systems registered to the ISO 14001 standard. In addition, 100 percent of the forests we own or manage in North America have been independently certified as meeting either the SFI or CSA standard (as of April 2008). In Uruguay, we will certify to appropriate national standards based on availability and customer need. See our Certification Standards for more information on our forestry management and certification systems.

Our certified status exceeds the averages for North America (35 percent) and Western Europe (52 percent), the two regions with the highest percentage of certified forests.

Manufacturing Facilities

All of our mills in the United States that use logs or wood chips as their raw material are independently certified as meeting the procurement provisions of the SFI standard. This includes all primary facilities—that is, those using logs or chips to produce pulp, paper, lumber, plywood and oriented strand board. In addition, 86 secondary manufacturing plants meet the fiber-sourcing provisions of the SFI standard. These include four of our I-joist plants, two Parallam facilities, four Laminated Veneer Lumber and two open web I-joist plants. Also, all of our primary mills* are independently certified as meeting either the chain-of-custody requirements of the CSA standard or the procurement provisions of the SFI standard.

What Certification of Our Procurement Systems Says About Our Products

• We know the areas our wood comes from and the type of supplier, whether they are certified forests owned by major timberland owners, small family forests, sawmills that supply residual chips, wood dealers or provincial governments in Canada. We can identify the percentage and source of certified content in our products.
• We use independent auditors. Auditors of the SFI and CSA standards must be accredited by the American National Standards Institute or the Standards Council of Canada. The SFI standard itself is governed by an independent board with equal representation from environmental organizations, the forest products industry, and the broader forestry community. The CSA standard's governance represents four interests: professional, environmental, government and business. Both standards provide for public consultation.
• The SFI standard, unique among certification systems, requires manufacturers to reach out to family forest owners and educate them about sustainable forestry.
• We monitor the use of best management practices by our log suppliers. These practices, developed state by state, specify proper techniques for protecting watersheds and riparian areas. In 2007, 93 percent of the primary raw material used by Weyerhaeuser's U.S. mills was harvested by professionally trained loggers.
• We promote sustainable forestry practices among those owners who have not yet pursued certification. In the United States, nearly half of our fiber comes from family forest owners for whom formal certification is a major hurdle.

Five Plants Meet SFI Chain-of-Custody Standard

Weyerhaeuser manufacturing facilities that have adopted the SFI chain-of-custody standard are:

• Evergreen, Ala., iLevel Trus Joist brand I-joists
• Natchitoches, La., iLevel Trus Joist brand I-joists
• Colbert, Ga., Parallam® mill
• Longview, Wash., liquid packaging, pulp
• NORPAC, Wash., paper products

Under the standard, wood from certified forests used to make these products is tracked through each stage of production. Modeled after a similar provision used by the European-based Programme for the Endorsement of Forest Certification, the chain-of-custody provision allows more precise claims about certified content and has opened the door for SFI-certified products to earn preferred status in European markets. Weyerhaeuser has several engineered wood products customers in Great Britain.
