Green development has been promoted as part of quality-oriented development in recent years. But inadequate attention has been devoted to how to achieve green development in the processes of both urbanization and suburbanization, driven by substantially increased income and affordability. This presentation attempts to elucidate this question based the international experience and personal observation. It is argued that while demands for basic materials for a good life remain, demands for a much improved living environment and associated cultural, spiritual, regulating, and other goods and services will intensify. How to fulfill these demands in view of the limited supplies of natural resources and environmental carrying capacity is the huge challenge we face. Human ingenuity and market and non-market forces must be mobilized effectively to that end.
