This document discusses using the built environment for social good. It addresses why this is important and what can be done in several areas: economic prosperity, environmental sustainability, social equity, cultural vitality, and physical safety and comfort. It proposes that systems change, innovative economics, and partnerships/collaboration are needed. Economics approaches include environmental and social accounting, linking finance and impact, and fiscal instruments. Partnerships and collaboration across different sectors are emphasized as the greatest degree of sustainable benefits can be achieved when resources are jointly managed for all. Examples of initiatives in Mauritius that use these approaches are also provided.
