Abstract: It is widely acknowledged that China’s economic miracle has been achieved at the expense of its natural capital and environment. In order to deal with this problem, the circular economy (CE) has been chosen as a national policy for sustainable development. National laws and regulations have been enacted to facilitate the implementation of CE and national CE demonstration projects have been initiated such that national benchmarking activities could be completed. China is the first country to release nationally focused CE indicators so that objective and credible information on the status of CE implementation can be recognized. These CE indicators are valuable metrics for policy and decision-makers and can help achieve CE goals and outcomes. This unique indicator system has not been communicated to international communities. This paper aims to more broadly introduce this unique national CE indicator system. China’s CE efforts are first detailed with various provisions of the national indicator system. A critical analysis of such an indicator system is presented. We show that certain benefits can be gained, but substantive revision is also needed due to the lack of a comprehensive set of sustainability indicators which should include social, business indicators, urban/industrial symbiosis, absolute material/energy reduction, and prevention-oriented indicators. Concerns related to barriers on implementation are also presented in this paper. The knowledge gained from Chinese efforts on CE indicators are valuable to both developed and developing nations seeking to implement sustainable development measures within their regulatory policies.

Abstract: With the world’s largest population and consistently rapid rates of economic growth, China faces a choice of whether it will move towards a more sustainable development trajectory. This paper identifies the different factors driving innovation in the fields of green chemistry and green engineering in China, which we find to be largely driven by energy efficiency policy, increasingly strict enforcement of pollution regulations, and national attention to cleaner production concepts, such as “circular economy.” We also identify seven key barriers to the development and implementation of green chemistry and engineering in China. They are (1) competition between economic growth and environmental agendas, (2) regulatory and bureaucratic barriers, (3) availability of research funding, (4) technical barriers, (5) workforce training, (6) industrial engineering capacity, and (7) economic and financial barriers. Our analysis reveals that the most crucial barriers to green chemistry and engineering innovations in China appear to be those that arise from competing priorities of economic growth and environmental protection as well as the technical challenges that arise from possessing a smaller base of experienced human capital. We find that there is a great deal of potential for both the development of the underlying science, as well as its implementation throughout the chemical enterprise, especially if investment occurs before problems of technological lock-in and sunk costs emerge.

Abstract: With the strategy of sustainable development is generally accepted, developed countries are harmonious developing oil and gas and ecological environment by developing circular economy and building cyclic ecological society. Circular economy has a successful practice in the oil and gas industry in some developed countries and has formed the varied and practicable development modes. In this paper, circular economy strategies of oil and gas exploitation in China have been analyzed. The author believes that would be helpful to “low extraction, high use and low emissions”.
