This chapter reviews current policies and practices in the Southeast Asian cities. It identifies opportunities and benefits existing in the green growth strategic areas and offers innovative policy recommendations for urgent implementation. The first section aims to answer the question “where are the potential areas?”. It presents the numerous areas of opportunity at the disposal of cities in the following six policy areas: land use and transport, energy, housing and buildings, water resource management, solid waste management, and green industries and services. The second section provides an analysis of the six policy areas in the case study cities. Gaps are identified and recommendations and useful examples from other OECD/non-OECD cities are highlighted. The third section highlights key policy strategies to maximise the complementarities and synergies across policy areas. Other cross-sector policy strategies particularly relevant in the context of emerging economies (demand-side policies, policies for long-term growth, ICT innovation for growth, etc.) are also discussed. The final section summarises the key message and indicates the way forward.
