Current Certification Status

Forest certification overview

Weyerhaeuser has chosen to maintain a Timberlands environmental management system that aligns with the ISO 14001standard, but is not third-party certified. Weyerhaeuser’s North American Timberlands have been third-party certified since 2001. After a several-month review, we determined we could maintain a robust environmental management system by:

• Clearly identifying how our EMS will align with the ISO 14001 standard
• Completing annual internal audits of the EMS
• Ensuring accountability by reviewing the internal audit results and follow-up actions items with top management

We remain committed to our long history of forest stewardship and will maintain our third-party certified, sustainable forest management certification. These certifications include SFI in the U.S., CSA in Canada and PEFC in our Uruguayan forest operations. We will continue to comply with all laws, regulations and company policies that guide our forest management activities.

Manufacturing certification overview (as of June 2009)

All of our primary mills in Canada are independently certified as meeting the chain-of-custody requirements of the CSA, PEFC or SFI standard.
