Sustainable Cities



A sustainable city or eco-city (also “ecocity”) is a city designed with consideration of environmental impact, inhabited by people dedicated to minimisation of required inputs of energy, water and food, and waste outputs of heat, air pollution (CO2), methane, and water pollution.

Therefore, the category of Sustainable Cities collects Blueprints and solutions focused on urban sustainability, as well as community building and active citizenship.
