i-sustain (I-S) is the website for two synergistic organizations with the shared mission of helping cities to use substantially less resources while improving the well-being of its citizens. The International Sustainability Institute (ISI), a 501-C3 non-profit, brings leaders from public, private and academic sectors together to implement superior urban strategies in their own cities. International Sustainable Solutions (ISS), a for profit corporation, inspires urban leaders about global best practices in sustainability by taking them to cities throughout the world that provide exceptional and replicable examples. ISS and ISI each have their own dedicated sections and content within this website, but share a common Resource Center, Photo Gallery and Contact Info.
