The Hammarby Model, which is the district’s attempt at a balanced, “closed-loop urban metabolism”, accounts for the unified infrastructure of energy, water and waste. In addition to the Hammarby Model infrastructure, the presence of urban-scaled density, access to multiple modes of transit with an emphasis on reduced car commuting, preservation and restoration of existing natural systems, and progressive construction and housing policies make Hammarby Sjostad an “effective demonstration that ecological and urban go together” by means of comprehensive planning (Beatley 2004:251, 255).
Stockholm is crafting policies and using planning to create a more sustainable society. The planning system in Sweden is termed “community planning”, which is a system that focuses on enhancing or altering the production and consumption of society that is normally left up to the market to determine. Planning is about formulating strategies to improve the quality of life for Swedes and the quality of the natural environment. Planning and environmental policies focus on this “dual” purpose of urban development patterns and green space preservation—crafting guidelines and policies to ensure that humans are close to nature and that natural areas maintain their ecological functions.
