Introduction

In 2014, the heads of state of China and France signed the Letter of Intent on Constructing Sino-French Wuhan Ecological Demonstration City as a sustainable development practice of Sino-French cooperation in coping global climate change. Based on the sustainable technologies and experience of China and France in the fields of urban planning, construction and management, the project will implement the concept of low carbon, ecology and industry-city integration, value renewable energy utilization and ecological environment technologies, highlight the low carbon transport system and green building application, and promote the development of technology R&D and innovation.

Objective of the practice

Sino-French Wuhan Ecological Demonstration City is positioned as a sustainable demonstration zone through which developing countries cope with environmental problems, an eco-prioritized and livable new city in China's Yangtze River Economic Belt, as well as a world-renowned, appealing, high-added-value and knowledge-based platform for Sino-French technical cooperation and cultural exchanges.

China has entered the stage of fast urbanization and achieved great success, but brought along many environmental problems: While becoming the world's second-largest economy, China is becoming the world's largest carbon emitting country. As climatic and environmental problems are becoming increasingly urgent, global consensus on energy conservation and emission reduction is becoming clearer. At the 2015 United Nations Climate Change Conference in Paris, in its "Intended Nationally Determined Contributions", China stated that it would peak carbon emissions and raise the proportion of non-fossil energy in primary energy to 20 percent by 2030. The master plan of Sino-French Wuhan Ecological Demonstration City was unveiled at the conference for the first time, and was promoted as a practice and exploration of sincere cooperation between a developed country and a developing country in addressing global climatic and environmental problems.

The concept of Sino-French Wuhan Ecological Demonstration City highly tallies with the concept of "innovation, coordination, green, opening and sharing" proposed by the Chinese government, and fits in with the eco-civilization construction advanced by China. The Chinese government also stressed that China must take a long-term view, take a road of ecology priority and green development, and develop on the basis of environmental protection in order to promote the development of the Yangtze River Economic Belt. The project should strengthen the concept of respect for nature, historical inheritance and low carbon, take environmental capacity and urban carrying capacity as the basis of determining city orientation and scale, initiatively advance green, cyclic and low carbon development, first create an industrial structure, growth pattern and consumption mode of energy resource conservation and environmental protection, and extend them to the rest of the country.

The project will promote the development of technology R&D and innovation, build Sino-French Tech Valley, and make the zone an important economic growth pole in Wuhan's urban development area.

China and France will cope with challenges in fields such as global climate change and environmental protection, explore more sustainable models of urban development, and push forward all-round cooperation and exchanges in fields such as urban planning, building, transportation, housing and energy efficiency. As both countries have long history and profound cultural deposits, the project will become an important platform for Sino-French cultural exchanges.
