Weyerhaeuser has become the first company to offer products which meet the new Sustainable Forestry Initiative (SFI) chain of custody standard.

The company can now offer Trus Joist I-joists made from wood from certified forests. The SFI chain of custody also ensures that non-certified material used by participating mills comes from non-controversial sources.

Three of Weyerhaeuser’s residential wood products operations situated in the southern US have had their raw material chain of custody procedures independently audited by SFI.

Cassie Phillips, Weyerhaeuser’s vice-president sustainable forests and products, said: “It allows us to assure our customers that a verified portion comes from forests managed to international standards for sustainable forest management.

“It is one more way to demonstrate to the market place Weyerhaeuser’s commitment to strong environmental performance.”
