The Regenerative Network Opportunity. Tells the story of David Gottfried's creation of the Regenerative Network, after founding the U.S. Green Building Council and the World Green Building Council (now with GBCs in over 90 countries). The Network includes hand-selected, exclusive leading green building product manufacturers and service providers. It is now going global, following the US model. The Network creates a "network effect" from its coalition of best-in-class members.
