We have a project on which we're using a large amount of wool, and we'd like to be able to take credit for biobased materials.  Since we're unable to find any wool that is Rainforest Alliance certified, we'd like to work with the manufacturer to provide "manufacturer-declared conformance to the SAN Sustainable Agriculture Standard."   Having reviewed the SAN standard, this doesn't appear to be a small task.   Has anyone had any success using this approach?  If so, do you have any documentation you could share to use as an example for this manufacturer?  For reference, the latest SAN standard is HERE.
