There are creative, affordable ways to address community development and also achieve goals of environmental sustainability. Approximately thirty case studies, based on interviews and usually also site visits, were completed during 2005. The case studies examined community gardening and urban agriculture, the greening of publicly controlled urban electricity and bus agencies, reuse centers and local business associations in the United States. Policy recommendations for city governments that emerged from the case studies are summarized here. There are many opportunities for financially pressed cities to assist the development of 'just sustainability' projects with minimal financial commitments. They can do so by rechannelling the purchasing decisions of public agencies, building partnerships with community organizations and developing the small business sector.
