S2 is you. Since 1991, local community members have gathered to align, amplify, and activate a more sustainable Seattle. S2’s Indicators for a Sustainable Community was emulated by over 90 cities and garnered an award from the United Nations, and the Center for Applied Sustainability changed our landscape forever. Today the S2 community includes upwards of thirty thousand people, twenty-five community organizers, and over a dozen gatherings a year. 

S2 wishes to acknowledge that its efforts take place on the traditional homelands of the Coast Salish peoples, including the unceded territory of the Duwamish Peoples.
