This presentation focuses on eco-city development initiatives in developing countries towards developing low carbon society. Rapid urbanization in developing countries may be the most significant demographic transformation in our century as it restructures national economies and reshapes the lives of billions of people. At the same time, urbanization has also contributed to environmental and socioeconomic challenges, including climate change, pollution, congestion, and the rapid growth of slums. But as a major style of residential environment, city, has been endowed new contents by new ideas ever emerged in the history and eco-city development has emerged as a way to address climate change issues in the context of developing sustainable cities in developing countries. Eco-cities have the potential to address many of the problems like climate change and socio-economic aspects associated with urban development, as does the concept of sustainable development in an urban setting. Drawing on lessons learned from the planning and development process of several low-carbon eco-cities, this paper explores the potential of an integrated urbanism approach for developing countries. The objective is not only to mitigate factors contributing to climate change, but to manage risk, maximize resilience, and promote the successful economic and social growth of the urban eco community in developing countries. An integrated urbanism approach to planning may give us the tools to leapfrog the environmental and public health costs of economic progress and create a new model for cities across the developing world.
