Some work has been done on rewriting the refab monifesto, helping fablabs keep an eye on effecient use of energy and materials, with the purpose of moving towards completely zero-waste and zero-emission labs.
This is a growing document that will appear on this page as wel as on the homepages of several fablabs. It is currently under revision, based on the discussion at Fabfuse 2012, and the new version will pop up soon.
