In an increasingly connected and interdependent world, the global sustainability challenge needs to be addressed by organizational networks from a whole-systems perspective. This study explores organizations through the lens of network theory and the Framework for Strategic Sustainable Development, with a special focus on networks already considering sustainability issues. The purpose of the research was to identify key factors critical to the success of an organizational network in the sustainability field, as well as define specific barriers to success for these networks. These specific factors and barriers to success are identified and explored across: Academic, Business, and Non-Profit sectors, with the ultimate objective of increasing the performance of Emerging Sustainability Networks (ESNs), removing barriers in the field, and planning strategically to achieve success in the sustainability movement.
