The Global Green Growth Institute (GGGI) is an international organization dedicated to supporting and promoting strong, inclusive, and sustainable economic growth in developing countries and emerging economies. GGGI interventions are premised on the promise of green growth—a simultaneous advancement of economic growth, environmental sustainability, poverty reduction, and social inclusiveness. GGGI develops and delivers its global products and services in partnership with government bodies, international organizations, academic institutions, civil society organizations (CSOs), and the private sector. Its interventions emphasize change in four themes—energy, land use, water, and green city development (GCD)—where member countries have highlighted gaps and demonstrated success, and that are therefore considered key to transforming these countries’ economies. Countries often have various definitions of a “city” and “urban areas.” These definitions are based on criteria such as population size and density, government structure, type of economic activity, physical characteristics, level of infrastructure, or a combination of these or other criteria. Thus, there is often a huge discrepancy in the definition of a “city” in one country versus another. GGGI recognizes these differences, and refers to a “city” in this document as any urban area that satisfies the criteria to be considered a “city” in the country of concern
