Consumer demand in Washington state for eco-friendly lumber is surpassing supply, even as a growing number of wood products firms turn to harvesting and selling timber from sustainably managed forests. The state Department of Natural Resources just announced that it would like to have as much as 1.1 million acres of state forestland certified as sustainably managed under the guidelines of the Forest Stewardship Council, an international certification group. Home Depot has approached the DNR seeking certified wood; last year, the corporation announced that by 2002 it will sell only lumber that has been certified as eco-friendly. Millions of acres of state, county, and municipal lands in Massachusetts, Minnesota, New York, Pennsylvania, and Wisconsin have already been certified as green.
