[en] The rapid development of online ride-hailing sharing economic platform provided an efficient way to mitigate the carbon emission of modern traffic in China. However, its development was blocked by the social management system whose update is relatively slow. How to resolve the conflict between the new economic paradigm development under the technology empowerment and the old public administration system and effectively solve the new economic and social problems it brought by are the major challenges for the healthy and sustainable development of this type of sharing economy. To shed light on the solutions to such conflict, the present paper conducts a case study on China’s largest online ride-hailing platform ‘Didi Chuxing’. The results indicate that the separation of ownership and use rights following the sharing economy brings a new approach to the efficient use of resources. The development of Didi displays a bottom-up policy innovation and institutional change. The path choice of enterprise development will affect its acquisition of legitimacy to a great extent. In this mobile Internet era, the public plays a critical role in shaping the new policy.
[en] Microalga-derived biodiesel plays a crucial role in the sustainable development of biodiesel in recent years. Literature related to microalga-derived biodiesel had an increasing trend with the expanding research outputs. Based on the Science Citation Index Expanded (SCI-Expanded) of the Web of Science, a bibliometric analysis was conducted to characterize the body of knowledge on microalga-derived biodiesel between 1993 and 2016. From the 30 most frequently used author keywords, the following research hotspots are extracted: lipid preparation from different microalga species, microalga-derived lipid and environmental applications, lipid-producing microalgae cultivation, microalgae growth reactor, and microalga harvest and lipid extraction. Other keywords, i.e., microalga mixotrophic cultivation, symbiotic system between microalga and other oleaginous yeast, microalga genetic engineering, and other applications of lipid-producing microalga are future focal points of research. .
[en] Pollution and the economy seem to have been inextricably linked throughout human history. Yet the relationship between environmental harm and economic development is complex and its understanding has been fragmented by disciplinary biases. Economists and environmental scientists have diverged on the urgency of abatement mechanisms and the marginal returns on investment on control technologies and social adaptations. The Environmental Kuznets Curve hypothesis has dominated this discourse, but is only one part of a broader pollution-economy nexus. As we consider a societal shift towards a circular economy, there is a need to consider a more integrated framework for analyzing the empirical evidence that connects pollution and economic development, and its implications for human well-being and the achievement of the sustainable development goals. This paper develops the main connections between pollution and economic development by reviewing the existing empirical evidence in the literature. (topical review)
[en] Road transport aspects are becoming increasingly important due to their high impact on economic, environmental and social sustainability. Considering the triple bottom line approach, best practices play a fundamental role within organisations. The purpose of this paper is to analyse several sustainable initiatives in road transport adopted by companies. Design/methodology/approach: The findings were developed and evaluated based on empirical data captured through a survey of 98 professionals involved in logistics and transport activities. Additionally, key literature on transport initiatives was reviewed to supplement the framework for the implementation of best practices in road transport.The exploratory study shows the importance of each best practice and determines the level of implementation of each initiative, comparing the results among different dealers (retailers, wholesalers, carriers and manufacturers), type of transport fleet and companies’ revenues. Research limitations/implications: The sample of 98 companies was based on simple search filters and the group is not wholly representative of all sectors. Respondents were mainly managers from Spain involved in logistics and transport activities. Surveyed companies included manufacturing, retailers, wholesalers and third-party logistics providers. Practical implications: The most common best practices in road transport are identified, including initiatives related to: efficiency, reusability, safety, optimization, emissions, waste and recycling. Initiatives that influence road transport are ranked by their degree of implementation in the companies analysed.
[en] Highlights: • A palygorskite-based ratiometric fluorescent probe for tetracyclines is designed. • The nanoprobe shows a real-time, visual and sensitive detection for tetracyclines. • The limit of detection of this nanoprobe is 7.1 nM. • The nanoprobe-immobilized test paper can realizes analysis by using a smartphone. - Abstract: A palygorskite (Pal)-based ratiometric fluorescent nanoprobe is designed in order to establish a real time, on-site visual, and highly sensitive detection method for tetracyclines (TCs). The nanoprobe comprises the green emissive dye molecules embedded in the natural Pal, which serve as the internal reference signal. The potential red-emissive seed-europium (Eu3+) ions are covalently bound on the surface of modified Pal, and they can act as the specific recognition element. The emission intensity of Eu3+ ions significantly increases upon TC addition. The nanoprobe fluorescence changes from green to yellow, orange, or red, thereby accomplishing the visual ratiometric fluorescent detection. This nanoprobe exhibits a high sensitivity with a detection limit of 7.1 nM and an excellent selectivity in monitoring the levels of TCs in milk samples. In addition, this nanoprobe is useful for quantitative determination of TCs, and it is not affected with intensity fluctuations due to instrumental or environmental factors. The nanoprobe-immobilized test paper realizes real-time TCs analysis by using a smartphone with an easy-to-access color-scanning APP as the detection platform. Moreover, the reported construction of visual ratiometric detection system follows the sustainable development idea, that is, from nature, for nature, and into the nature.
[en] Highlights: • Global environmental challenges require scientific advice for policy. • The IPCC has pioneered new ways of assessing scientific knowledge across a range of disciplines and topics. • Three trade-offs are visible within IPCC assessments, which provide lessons for other global challenges. • These trade-offs are valuable for assessing environmental knowledge of antimicrobial resistance (AMR) for science advice. - Abstract: In the context of ongoing debates about the place of knowledge and expertise in the governance of global challenges, this article seeks to promote cross-sectoral learning about the politics and pitfalls of global science advice. It begins with the intertwined histories of the Intergovernmental Panel on Climate Change (IPCC) and the global climate policy regime, before examining the politics of different ‘framings’ of the climate problem and the challenges of building and communicating scientific consensus. We then identify three important trade-offs which the IPCC has had to negotiate: global versus local; scientific disinterestedness versus policy-relevance; and consensus versus plurality. These lessons are especially timely as global institutions begin to convene knowledge to address urgent sustainable development challenges posed by anti-microbial resistance (AMR). While the IPCC experience does not provide a wholly transportable model for science advice, we show why similar trade-offs need to be addressed at an early stage by architects of advisory systems for AMR as well as other global challenges.
[en] This review article makes six observations about the current body of research on the societal impacts of a changing Arctic. First, climate change and globalisation are the dominant drivers of societal impacts in the Arctic. Second, many contributions focus on the impacts in concrete sectors of society, often from an opportunities-and-risks perspective, which tends to blur the boundary to more policy-oriented work. Third, the mantra of the sustainable development of the Arctic or Arctic sustainability pervades considerations of Arctic societal impacts. Fourth, societal and environment change in the Arctic is increasingly analysed using the image of the Global Arctic, highlighting the inextricable linkages between Arctic and global processes and systems and thus the entangled fate of the North and the entire globe. Fifth, an increasing number of actors is seen as being involved in societal and environmental transformations in the Arctic, often conveyed through the (often ill-defined) stakeholder concept. Sixth, Arctic indigenous peoples are depicted as the group most vulnerable to the societal impacts of a changing Arctic, but are increasingly the subject of research in the form of rights-holders and active participants in governance, law, politics, and research. Challenges for future research include achieving greater clarity and reflexivity around key concepts, and de-essentialising the Arctic via the use of comparative methods on cases both within and beyond the Arctic.
[en] Consumer’s green buying behavior has a significant effect on achieving global sustainable development. Based on this condition, the present study aimed to explore the effects of individual’s personality traits on consumer’s attitude toward green buying and intention to buy green products. Questionnaires survey method was employed to collect data, from Chinese consumers, and the data were analyzed by using SPSS software and Smart-PLS 2.0. The results indicated that the personality traits of extraversion, agreeableness, openness to experience and conscientiousness positively affect consumer’s attitude toward green buying. Consumer’s attitude, conscientiousness, openness to experience and extraversion affect consumer’s intention to buy green products positively and significantly. Furthermore, a multi-group SEM (structural equation model) analysis was conducted to explore the impacts of several demographic variables (such as age, gender and birthplace) on the relationships between personality traits, attitude and intention. The results indicated that the effects of agreeableness and conscientiousness on attitude and the effects of agreeableness, conscientiousness and attitude on intention to buy green products are stronger in Gen Y, female and southern region subgroups. The effects of extraversion and openness to experience on attitude and intention to buy green products are stronger in non-Gen Y, male and northern region subgroups. Finally, this research discussed the implications and pointed out the suggestions for future research.
[en] Highlights: • This study formulated a detailed conservation strategy for the coastal and marine environment of Bangladesh. • The strategies of nine sectors, their objectives and the action plan towards achieving these objectives were outlined. • Implementing these strategies will play an instrumental role in enhancing blue growth and achieving SDGs. - Abstract: The coastal and marine ecosystem provides critical ecosystem services to millions of people living in a densely populated Bangladesh. In recent decades, the ecosystem faces a number of challenges derived from both natural and anthropogenic sources that put pressures on the sustainability of the social and ecological system. Moreover, the government recent initiatives to enhance the ocean-based blue economy and achieve sustainable development goals, particularly SDG 14 calls for developing a comprehensive conservation strategy for the coastal and marine environment. Based on literature review and stakeholders consultation, this study formulated a detailed conservation strategy for the coastal and marine environment of Bangladesh. The strategy of nine interrelated sectors, their objectives and the action plan towards achieving these objectives were outlined. Implementing these strategies will play an instrumental role in enhancing blue growth and achieving sustainable development goals either directly or indirectly.
[en] Climate changes have been recognized to be one of the most challenging issues of the humanity. The goal of this paper is to evaluate different energy generation scenarios for the national Romanian energy sector targeting a sustainable reduction of greenhouse gases (GHG) emissions. Three scenarios of carbon dioxide (CO2) emissions reduction until 2050 were proposed: reduction by 50%, 70% and 90% from the 2012 levels. As result, three National Determined Contribution (NDC) levels of CO2 emissions avoiding have been calculated. The IAEA-MESSAGE (International Atomic Energy Agency Model for Energy Sustainable Strategy Alternatives and their General Environmental Impacts) computer tool was used to perform the analyses. The paper’s results show that a sustainable reduction can be assured for the first two scenarios, with some minor gaps. The paper concludes that CO2 emissions reduction levels higher than by 70% of 2012 levels are not sustainable. (author).
