The three prerequisites for greening urban infrastructure:
- Cities must adopt aggressive energy reduction goals and best-practice approaches to urban planning.
- Innovative financing strategies are needed to provide $20 trillion to $30 trillion in funding for additional up-front capital costs, with developed nations working together to assist developing nations in their low-carbon urban infrastructure initiatives.
- The latest technological advances must be utilized to support and enable the planning, construction, and usage of urban infrastructure in all cities.
