In this report NRDC and 18 other non-profit organizations jointly recommend ten key principles of low-carbon urbanization for Chinese cities. These principles fall into three categories: Low-Carbon Urban Form, Resource Efficiency, and Inclusive Urban Governance. Most Chinese cities have already resolved to take a green development approach that stresses a more rational spatial layout, green transportation, low-carbon industry development, renewable energy, and good governance among other things. Building off of this foundation, we have identified specific principles that address the most important and pervasive weak points observed in Chinese cities. These recommended principles are essential features of a holistically low-carbon city.
