The idea of a circular economy (CE) has become prominent in both European and Chinese policy making. Chinese and European perspectives on a CE share a common conceptual basis and exhibit many similar concerns in seeking to enhance resource efficiency. Yet they also differ, and this article explores differences in the focus of CE policy in China and Europe. We present evidence on the differing understandings of the CE concept in Chinese and European policy discourse, drawing on qualitative and quantitative analysis of policy documents, media articles, and academic publications. We show that the Chinese perspective on the CE is broad, incorporating pollution and other issues alongside waste and resource concerns, and it is framed as a response to the environmental challenges created by rapid growth and industrialization. In contrast, Europe's conception of the CE has a narrower environmental scope, focusing more narrowly on waste and resources and opportunities for business. We then examine similarities and differences in the focus of policy activity in the two regions and in the indicators used to measure progress. We show differences in the treatment of issues of scale and place and different priorities across value chains (from design to manufacture, consumption, and waste management). We suggest some reasons for the divergent policy articulation of the CE concept and suggest lessons that each region can learn from the other.

In this article, we analyse the evolution of circular economy (CE) scientific knowledge in the most productive political geographies in the field, namely the European Union (EU) 28 and China by using bibliometric, network and survey analysis. Our objective is to provide a systemic, quantitative, visio-temporal review of the evolution of the CE scientific research field. Using Web of Science (WoS) database and Scopus, we trace the bibliometric characteristics of key research terms, their co-occurrences, publication (co)authorships at multi-level (author, institute, city, region, country), issue journals, literature citations and funding sources. Our findings from co-authorship, citation, co-citation, bibliometric coupling, co-occurrence and network analyses indicate that China and the EU have the highest amount of CE literature published and are each other's primary source of co-authorship. Emerging or reiterated main themes in the joint CE literature between EU and China are emergy analysis, indicators; resource efficiency, food waste, zero waste; eco-cities, lifestyle and governance. There appears a good potential for international cooperation in the sectoral fields of automotive, construction and demolition, critical raw materials; in business, (new) business models, product and services platforms, and from security perspective, resource security, security of supply, given the paucity of co-authorship between China and the EU under these themes. In China; Beijing, Shenyang, Dalian, Shanghai are the most active cities with a central role of Chinese Academy of Sciences at institution level of analysis. The most active EU institute is the Delft University of Technology in South Holland, the Netherlands. In Europe, we observe countries citing CE literature yet with no or few publications. Journal of Cleaner Production is the most important outlet for publications on CE and also for joint publications of CE researchers in both China and EU-28. We conclude our article with future research agendas, and a positive note on existing interests in international cooperation based on our survey participated by highly-cited CE authors.

Repair of mobile phones fits with the vision of a circular economy in an urban context and with the Sustainable Development Goal 11 Sustainable Cities and Communities. Drawing on the literature about firm level competitiveness and closed-loop design through repair, remanufacturing or recycling, we analyze the business ecosystem of independent mobile phone repair shops in the Netherlands, Poland and China as a glocal business activity. The analysis is based on primary data collection through a questionnaire to independent repair shops in the Netherlands (n = 130), Poland (n = 443) and China (n = 175) with response rates of 13%, 12%, 40%, respectively; and 17 interviews in the Netherlands, 40 in Poland, and 70 in China. Findings indicate that to maintain a strong position in the local market and to sustain the trust of customers, independent mobile phone repair shops offer a range of customized services based on direct contact with customers. In China, the increasing prices of spare parts and falling prices of mobile phones constitute the most important challenges, whereas in the Netherlands and Poland, the most important challenges are the competitive pressures from informal repair activities, and new repair shops. Our research also revealed that repairability strongly depends on the global manufacturers’ circularity choices.

In this article, we highlight the pressing need for integrating the windows of opportunities that digital transformation of education opens up with circular economy education to accelerate the achievements of sustainability outcomes. Circular economy transition, as a multi-scalar process, relates to several contexts, e.g., product, firm, industry-level transformations ranging from designing local socio-technical solutions to greening global value chains, with multi-level policy and business implications for finance, production, distribution, consumption that are fundamentally consequential to everyday life, work and learning. Drawing on theories of neo-capital, multi-level perspective and structuration, and as methodology, using content analysis and qualitative meta-synthesis of scientific publications in digital education for sustainability, we blended our findings into multi-level, multi-domain structuration blueprints, which capture the complexity of value emanating from the interactions among external structures, internal structures of agents, active agencies and outcomes, for circular economy open online education and massive open online course instructional designs. We conclude that learning and creating multiple values to increase social–ecological value, complementarily to economic value, necessitate activating the complexity of value embedded in digital education and circular economy transitions with cu2005mizable niches of learning preferences and journeys of individuals and groups, within broader (and evolving) technological, organizational and institutional structures.

Globally, construction materials are the largest materials flow entering urban areas after water. The tremendous use of building materials poses heavy threats to resources and the environment. In order to better understand the GHG emissions embodied in the abundant building material consumption of Shanghai's buildings and search for approaches to reduce GHG emissions, this study explores the building consumption and the embodied GHG emission in Shanghai's buildings through life cycle assessment. Novel and localized life cycle inventories are applied. Based on our findings, the average annual growth rate of new constructed area in Shanghai was around 10% since 2000 to 2016. Concrete, brick, sand, gravel and cement (non-concrete use) appear as the main materials used. High GHG emission burden materials per kg are revealed to be steel, lime, wood, glass and cement (non-concrete use). Accounting the annual material consumption in 2016, steel, cement (non-concrete use), concrete and brick are found have the highest contribution to embodied GHG emission in Shanghai. The decoupling analysis reveals Shanghai experienced a general trend from non-decoupling to relative decoupling between building material use and GDP in recent 17 years. Findings in this study indicate for the high GHG emission burden materials such as steel and lime, reducing the energy use and using less CO2-intensive energy sources during manufacturing are likely to be the most effective approaches. In terms of the highly consumed building materials such as concrete and brick, the focus should be on reducing consumption or looking for substitute materials with lower GHG burden per unit.

In this article, a 3-step neuro-fuzzy expert decision support system is constructed in order to investigate the multifaceted performance interdependencies among 17 SDG performance scores across 162 UN Member States. The direct influence matrix among 17 SDGs, which would be filled by policy experts in interpretive structural modeling, is instead populated by computational intelligence. Results indicate that, the most influential performance drivers are SDG12 (Sustainable Production and Consumption), SDG 9 (Industry, Innovation and Infrastructure) and SDG 11 (Sustainable Cities and Communities) at global level. Yet these findings highlight the importance of establishing and enhancing local infrastructures and communities, innovative and sustainable supply and demand content to increase overall SDGs performance globally. Performance linkages SDG 5 (Gender Equality) and SDG 13 (Climate Action) are global common denominators across localities for positive evolution of overall SDGs performance. Local policy mixes between performance driver and linkage SDGs are recommended by taking eight dependent SDG performances (SDG 10, 16, 15, 8, 6, 17, 7, 2) into account as action contexts. Four autonomous (less influential) SDG performances (SDG 1, 3, 4, 14) remain to be integrated. Conclusions call for a global unity in diversity, local policy mixes by all cities and communities around the globe.
