Eco-cities in the People's Republic of China are planned urban development projects that are envisioned as models of sustainable development, seeking to address challenges of rapid urbanization, environmental degradation, and resource constraints.
The concept of eco-cities in China gained significant attention and support from the government in the early 2000s, driven by the need to address the country's urbanization challenges, and combat pollution and resource depletion. The Chinese government, through various initiatives and policies, has encouraged the development of eco-cities across the country, promoting them as showcases of sustainable urban development and engines of economic growth. China now boasts the largest eco-city development program in the world.
Most Chinese eco-city projects remain under construction, limiting the ability to assess the overall efficacy of these programs. While proponents argue these cities represent innovative solutions to urban sustainability with the potential to reduce carbon emissions, enhance resource efficiency, and improve the quality of life for urban residents, some critics have raised concerns about the efficacy, funding, implementation gaps, and environmental impact of these projects.
Concepts and trends There is no singular, official definition of an eco-city; however, these developments generally strive to reduce fossil fuel consumption, carbon emissions, and dependence on natural resources while emphasizing the preservation of local ecosystems.
The creation of eco-cities in China parallels a global trend in urban sustainable development. However, these Chinese eco-cities also promote unique characteristics rooted in traditional Chinese cultural values that emphasize harmony with nature, similar to concepts like feng shui. Chinese ideologists insist that the achievements of Western industrial civilization contributed to the rapid development of industry in the New and Modern times, but the Eastern civilization, having assimilated its achievements, reawakened and revived the essence of Chinese traditional philosophy, which is the basis for modern eco-cultural construction in the PRC. In this regard, in order to solve modern problems, China must rely on traditional philosophy, accumulating the achievements of the past to solve the problems of the future. This concept is called "Five in One" (五位一体). According to it, eco-cities (also sometimes referred to as "green cities") in China should be developed based on the principles of sustainable development, combining in their nature the principles of economic, political, cultural, social and ecological construction. The government has promoted eco-cities as a means of achieving the goals of creating a harmonious society and an ecological civilization.
Others state that current Chinese eco-city development and China's overall relationship with the environment have far less to do with these beliefs, such as Confucianism, than ideologists claim, with current perspectives and design plans aligning more with western beliefs. This ideological incongruence has impacts on China's current and past eco-city projects, especially in regards to urban planning and development.
Common features Chinese eco-cities are typically initiated as pilot projects led by local governments, often with sponsorship from the central government. This approach has resulted in a diverse patchwork of development strategies across different cities. Chinese eco-city development has generally favored the construction of new developments rather than retrofitting existing urban spaces.
Urban design in Chinese eco-cities frequently emphasizes compact, mixed-use layouts to reduce urban sprawl. These designs often aim to conserve farmland for increased food security and to encourage sustainable transportation by prioritizing walkability, implementing bike-share programs, and expanding public transit options.
Renewable energy usage is a key priority in eco-city development, with a focus on solar, wind, bioenergy, and hydropower. Efforts to improve energy efficiency encompass various initiatives, such as recycled heat systems, smart grids, and green buildings. Recycling programs are also commonly integrated into Chinese eco-cities.
These cities often seek to attract low-carbon industries and experiment with innovative approaches including circular economies, low-carbon ports and food production, and ecotourism. Environmental technology is often the primary means of meeting city sustainability goals, with eco-cities serving as testing grounds for new urban technologies.
Funding Construction is typically managed through local pilot projects with central government sponsorship. As a result, funding mechanisms vary significantly, with some projects receiving robust national support and substantial foreign investment, while others rely on local funding or a combination of funding sources. Disparate funding sources have resulted in a wide range of characteristics among eco-cities, as local governments are encouraged to innovate and adopt different strategies.
Many eco-city projects engage international partners to secure funding. International collaboration allows eco-cities to tap into additional resources, leverage international knowledge and experience, and enhance brand value.
Comparison with global eco-cities
One key distinction between Chinese eco-city development and global programs lies in the level of central government involvement. While global eco-city projects are typically fragmented, singular projects initiated by local governments, Chinese eco-city development is actively encouraged and promoted by the central government, resulting in a large volume of projects. Unlike the bottom-up model commonly found in global projects, where local governments lobby for national recognition, Chinese projects follow a top-down approach by implementing local-level projects that respond to existing national targets and policies.
As a consequence, Chinese eco-city projects tend to be larger in scale. While global eco-city development often focuses on retrofitting existing urban spaces, China's initiatives predominantly involve building new cities from scratch. This approach is primarily driven by the need to address the challenges of rapid urbanization in the country. Due to their ambitious scale, Chinese eco-city projects typically have longer construction timelines and require larger investment and funding streams. Reliance on external investment, especially for long-term and large-scale funding, has presented challenges in completing many projects.
Ecological Island Carbon Neutrality Demonstration Zones Ecological Island Carbon Neutrality Demonstration Zones are an extension of the eco-city concept that applies related environmental policies and infrastructure across entire island communities. Such projects typically focus on ecologically sensitive or geographically isolated areas, where planning can be implemented at the scale of the island as a whole. Chongming Eco-island is an example of this approach in China, while similar initiatives have been proposed or considered for other islands.
History Rapid changes in the Chinese economy and population have led to the adoption of eco-city construction as the primary strategy for urban development in China.
Background Beginning in the late 1970s, the reform and opening up triggered a massive wave of urbanization, considered the largest migration in human history, with over 500 million people relocating from rural areas to cities since the 1980s. These reforms transformed China from a predominantly rural society to an urban one, resulting in significant environmental challenges and exacerbating climate change.
The country's rapid industrialization, driven by the expansion of heavy industries and manufacturing, has also had detrimental environmental consequences. Industrialization has resulted in high pollution and a substantial increase in greenhouse gas emissions which have made China the largest emitter of greenhouse gasses globally. The country's transition to a market-based economy further fueled urbanization, as the Chinese government has actively promoted urban migration to boost domestic demand and stimulate economic growth.
The construction of cities to accommodate the growing urban population has had adverse environmental impacts. The conversion of natural land into urban centers has led to the formation of heat islands and increased pollution. The construction of urban infrastructure, including roads and buildings, has also contributed to increased carbon emissions.
Supporting the burgeoning urban population has also contributed to increased carbon emissions, with cities accounting for the majority of Chinese emissions. Despite urban buildings typically being more energy-efficient, per capita emissions in urban areas surpass those in rural areas. Urbanization has further heightened China's energy demand. Construction and energy requirements for buildings alone account for approximately half of China's energy-related emissions. The rise of consumerism in China has also contributed to increased environmental impacts, with urbanization and consumer culture driving greater natural resource consumption, sedentary lifestyles, and changing diets which have also resulted in rising obesity rates and lifestyle diseases. The expansion of urban infrastructure and services to meet the needs of city residents has also intensified energy consumption and emissions.
These factors have encouraged the adoption of eco-city construction as a response to the ecological and social challenges stemming from China's rapid urbanization, industrial development, and economic growth. Eco-cities now serve as an official method for mitigating the impacts of urbanization and in China's climate change strategy.
Because its adoption is so encouraged, over the past 30 years interest in and research about eco-cities and their development has increased significantly in China. There has been a distinct focus on how to sustainably develop urban areas and create new green infrastructure as it relates to these urban areas.
Policies Rapid urbanization in China has led to social and environmental challenges, but it has also provided an opportunity to embrace eco-cities to support urban growth and promote sustainable new cities that can cater to the expanding urban population for generations. Recognizing the need to reduce carbon emissions and address climate change, the Chinese government has embraced the concept of eco-cities as a means of achieving these national goals.
China and the United Kingdom in 2005 announced an initiative to jointly create "the world's first carbon neutral eco-city." The contemplated development, Dongtan Eco-City, was not ultimately completed. It later influenced other approaches to Chinese eco-cities.
In 2006, the Chinese government announced its commitment to climate issues through the 11th Five-Year Plan, which introduced a renewable energy plan, new regulations, and incentives for local governments. The 17th National Congress of the Chinese Communist Party in 2007 introduced the idea of a "low-carbon eco-city model" as part of a broader "eco-culture" framework, describing it as part of an effort to encourage sustained peace and common prosperity. Also in 2007, the government officially endorsed the concept of an "ecological civilization" and promoted the eco-city model for urban development.
The Ministry of Ecology and Environment initiated the first eco-city program in 2008, followed by the Ministry of Housing and Urban-Rural Development's introduction of the low-carbon eco-city program in 2009 and the National Development and Reform Commission's low-carbon city program in 2010.
