The concept of “green growth” is tied to the “green economy for sustainable development and poverty reduction,” the first theme of the Rio + 20 United Nations Conference on Sustainable Development (UNCSD). Furthermore, formulating strategies for making cities and human settlements inclusive, safe, resilient, and sustainable has emerged as one of the 17 Sustainable Development Goals. To effectively achieve green growth, developing a low-carbon society should occur at multiple levels: international, regional, national, and subnational. The Asia Pacific region, the site of rapidly growing populations and economies, can show the global impact of sustainable development partly because this region includes a key advanced economy, Japan, and two key emerging economies, China and Indonesia.
