The Urban Green Growth in Dynamic Asia project explores how to promote green growth in cities in Asia, examining policies and governance practices that encourage environmental sustainability and competitiveness in a rapidly expanding economy. This synthesis report presents the results of case studies along with practical policy recommendations, reflecting the local contexts of Southeast Asia. While Southeast Asian cities are affected by a range of economic, infrastructure, environmental and social challenges, ongoing rapid development offers opportunities to shift towards greener growth models. The concept of urban green growth can be a powerful vector of sustainable development, by emphasising the existence and potential of co-benefits between economic and environmental performance.
