The plot thickens:
...the conservation chamber of SFI’s Board of Directors sent an open letter to media regarding ForestEthics.  The letter is below.   I encourage you to demonstrate your support by commenting on this letter, the SFI program and all the great work the more than 2,500 organizations involved in our program do.
Excerpts from said letter:
As members of the Conservation Chamber of SFI’s Board of Directors, we take strong exception to ForestEthics’ current campaign against SFI. ... The six of us who serve on the Environmental Chamber of the SFI Board have dedicated our lives to conservation. We would not be on the SFI Board if we did not believe it is a credible forest certification program, which we are able to advise and guide through our combined and diverse conservation expertise.
UPDATE: The president and CEO of SFI guest-posts over at GreenBiz about what to do when Forest Ethics comes knocking:
We aim to work constructively with organizations throughout the supply chain to ensure that these campaigns don't cause procurement professionals to throw up their hands and decide that responsible forestry is more trouble than it's worth.
