Is there a way to say in one sentence what sustainable communities are for the purpose of EE? Here is a great definition of Sustainable Communities From the Institute for Sustainable Communities (http://www.iscvt.org/impact/definition-sustainable-community/) : [A sustainable community is one that is economically, environmentally, and socially healthy and resilient. It meets challenges through integrated solutions rather than through fragmented approaches that meet one of those goals at the expense of the others. And it takes a long-term perspective – one that’s focused on both the present and future, well beyond the next budget or election cycle.
 
A sustainable community’s success depends upon its members’ commitment and involvement through:
Active, organized, and informed citizenship.
Inspiring, effective, and responsive leadership.
Responsible, caring, and healthy community institutions, services, and businesses.]
