Goal: Implement compact, sustainable cities in Asia that are ecological, livable, and smart
Positioning: To serve as a key proponent for the development of compact, low carbon cities in Asia using a holistic and integrated urban management approach
Principle: Employ a multi-disciplinary, multi-sectoral approach to every stage of a city’s
development cycle
Tool: Sustainable System Integration Model (SSIM)
• Fully leverage AECOM’s professional experience in planning, design, economy, energy, transportation, ecology, environment,
water management, green construction and other fields
• Committed to the concept of sustainable development
• Participate in the entire life cycle of urban and land development, from planning to implementation, monitoring, management
and continuous optimization
