Green Cities
Which investments are required? The ultimate test of the long-term feasibility of any urban development model is its sustainability, since a primary purpose of an urban area is to provide a venue for economic activity undertaken by its inhabitants. Thus, environmental sustainability holds the key to long-term survival of urban environments, as well as sustained economic advance. Six types of investments are required for achieving green cities, and thus ensuring the long-term survival of the urban environment: (i) low-carbon transport systems; (ii) a green industrial sector; (iii) energy-efficient buildings; (iv) greening of the city itself; (v) green, resilient infrastructure; and (vi) intelligent systems (Figure 2). Asia’s urban policy makers are increasingly aware of the importance of pursuing these six types of investments. This awareness is reflected in the fact that Asian cities are increasingly embracing urban development models that reduce the rate at which energy is consumed by buildings, industries, and transport systems.
