Staying at the top is getting tougher and more challenging due to the fast-growing and changing digital technologies and AI-based solutions. The world of technology, mass customization, and advanced manufacturing is experiencing a rapid transformation. Robots are becoming even more important as they can now be coupled with the human mind by means of brain–machine interface and advances in artificial intelligence. A strong necessity to increase productivity while not removing human workers from the manufacturing industry is imposing punishing challenges on the global economy. To counter these challenges, this article introduces the concept of Industry 5.0, where robots are intertwined with the human brain and work as collaborator instead of competitor. This article also outlines a number of key features and concerns that every manufacturer may have about Industry 5.0. In addition, it presents several developments achieved by researchers for use in Industry 5.0 applications and environments. Finally, the impact of Industry 5.0 on the manufacturing industry and overall economy is…

Digitalization is revolutionizing the way business is conducted within industrial value chains through the use of Internet of Things (IoT) technologies, intensive data exchange and predictive analytics. However, technological application on its own is not enough; profiting from digitalization requires business model innovation such as making the transition to advanced service business models. Yet, many research gaps remain in analyzing how industrial companies can leverage digitalization to transform their business models to achieve sustainability benefits. Specifically, challenges related to value creation, value delivery, and value capture components of business model innovation need further understanding as well as how alignment of these components drive sustainable industry initiatives. Thus, this special issue editorial attempts to take stock of the emerging research field through a literature review and providing a synthesis of special issue contributions. In doing so, we contribute by developing a framework that communicates and sets the direction for future research by…

The rapid pace of developments in Artificial Intelligence (AI) is providing unprecedented opportunities to enhance the performance of different industries and businesses, including the transport sector. The innovations introduced by AI include highly advanced computational methods that mimic the way the human brain works. The application of AI in the transport field is aimed at overcoming the challenges of an increasing travel demand, CO2 emissions, safety concerns, and environmental degradation. In light of the availability of a huge amount of quantitative and qualitative data and AI in this digital age, addressing these concerns in a more efficient and effective fashion has become more plausible. Examples of AI methods that are finding their way to the transport field include Artificial Neural Networks (ANN), Genetic algorithms (GA), Simulated Annealing (SA), Artificial Immune system (AIS), Ant Colony Optimiser (ACO) and Bee Colony Optimization (BCO) and Fuzzy Logic Model (FLM) The successful application of AI requires a good understanding of the relationships between AI and data…

The UN 2030 agenda of Sustainable Development Goals (SDGs) envisions a future of inclusive equity, justice and prosperity within environmental limits, and places an important emphasis on education as stated in Goal 4. Education is acknowledged as a means for achieving the remaining Goals, with sustainability as a goal for education in target 4.7. However, the interconnectedness of the SDGs and the complexity of sustainability as a concept make it difficult to relate the SDGs to educational learning outcomes, with what Education for Sustainable Development (ESD) aims to achieve, left in ambiguity. Using systems thinking, we developed a framework that redefines ESD as a tool that can deliver the transformation required for society to reach a sustainable state. Using the SDGs as end points for this state, and through a participatory approach, education stakeholders and learners work together to construct a common vision of sustainability, identify the competences needed, and develop appropriate pedagogies and learning strategies. The framework allows for the development of evaluation…

The aim of the present research is to provide a comprehensive review about the current challenges related to food security and hidden hunger. Issues are presented according to major factors, such as growing population, changing dietary habits, water efficiency, climate change and volatile food prices. These factors were compiled from reports of major international organizations and from relevant scientific articles on the subject. Collecting the results and presenting them in an accessible manner may provide new insight for interested parties. Accessibility of data is extremely important, since food security and its drivers form a closely interconnected but extremely complex network, which requires coordinated problem solving to resolve issues. According to the results, the demand for growing agricultural products has been partly met by increasing cultivated land in recent decades. At the same time, there is serious competition for existing agricultural areas, which further limits the extension of agricultural land in addition to the natural constraints of land availability.…

In today’s world, social media is playing an indispensable role on the learning behavior of university students to achieve sustainable education. The impact of social media on sustainable education is becoming an essential and impelling factor. The world has become a global village and technology use has made it a smaller world through social media and how it is changing instruction. This original study is amongst the few to perform a focalized investigation on revealing the relationship between positive and negative characteristics of social media and the learning attitude of university students for sustainable education. However, this study aims to examine the constructive and adverse factors that impact on students’ minds and how these helped students to share positive and negative aspects with others. It is increasingly noticeable that social networking sites and their applications present enormous benefits for as well as risks to university students and their implications on students’ psychological adjustment or learning behaviors are not well understood. This study adapted the…

The availability, access, utilization and stability of food supply over time are the four pillars of food security which support nutrition outcomes. Addressing the issues raised globally around these pillars remains a challenge. The Food and Agriculture Organization of the United Nations (FAO) 2017 report “The future of food and agriculture: trends and challenges” outlined the challenges which will have to be addressed in order for sustainable agricultural services to cost-effectively meet the growing food demand of the world population. In this study, we systematically analyzed the future challenges of the agriculture and food systems by focusing on (1) their root causes and trends; and (2) the interlinkages among the solutions proposed to address the challenges using social network analysis tools. It found that, if trends leading to extreme poverty are reversed, several other challenges will also be partially addressed and that climate change has the highest impact on the network of trends. Improving food security would have positive impacts on food access and utilization. The…

A sustainable business model describes the rationale of how an organization creates, delivers, and captures value, in economic, social, cultural or other contexts in a sustainable way. The process of sustainable business model construction forms an innovative part of business strategy. Different industries and business types have utilized sustainability business models to satisfy their economic, environmental and social goals simultaneously. This study is conducted to present the state of the art of sustainable business models in various application areas. The business models are classified and reviewed in different application groups. To do so, a review is conducted, and the findings reveal that the application of sustainability business models can be classified in 16 unique categories. The key contribution of this study is providing an insight about the state of the art of sustainable business models in various application areas and its research path.

The rising population and reduction in the amount of land and some other resources have created tremendous pressure on current agricultural producers to meet the increasing food demands. To cope with this challenge, certain key inputs, such as fertilizers and other chemicals, are overused, which are worsening the surroundings. This intensive agricultural production without adherence to ecological sustainability has led to declining soil health, land degradation, and severe environmental problems. So, future efforts to feed the growing population should aim for greater agricultural production within sustainable environments. In this regard, innovative steps are needed, as business-as-usual policies lack the potential to cope with these challenges. The concept of agricultural sustainability and various soil and crop management strategies (SCMS) that have been designed to optimize crop yield under sustainable environmental conditions are discussed, including nutrient management, site specific nutrient management (SSNM), integrated nutrient management (INM), integrated soil fertility…

This study analyzed whether a systematic relationship exists between corporate social responsibility (CSR) performance and corporate financial performance using 191 sample firms listed on the Korea Exchange. The Korea Economic Justice Institute (KEJI) index of 2015 was used to measure CSR performance; profitability and firm value were used to measure corporate financial performance. Return on assets was used as a proxy for profitability, and Tobin’s Q was used as a proxy for firm value. The correlation between these variables and CSR performance was examined through correlation and regression analysis. The results confirm that CSR performance has a partial positive correlation with profitability and firm value. These results are partly consistent with those of previous studies reporting a positive relationship between CSR and Korean firms’ financial performance using the KEJI index before 2011. In the relationship between CSR performance and profitability, only social contribution yields a statistically positive correlation. Analysis of the correlation between CSR performance and…

Environmental, social, and governance (ESG) rating agencies, acting as relevant financial market actors, should take a stand on working towards achieving a more sustainable development. In this context, the objective of this paper is, on the one hand, to understand how criteria used by ESG rating agencies in their assessment processes have evolved over the last ten years and, on the other hand, to analyze whether ESG rating agencies are contributing to fostering sustainable development by the inclusion of sustainability principles into their assessment processes and practices according to the ESG criteria. This research is based on a comparative descriptive analysis of the public information provided by the most representative ESG rating and information provider agencies in the financial market in two periods: 2008 and 2018. The findings show that ESG rating agencies have integrated new criteria into their assessment models to measure corporate performance more accurately and robustly in order to respond to new global challenges. However, a deep analysis of the criteria also shows…

Banks must meet the needs of their customers in order to achieve sustainable development. The aim of this paper is to examine service quality dimensions, by using the modified SERVQUAL model, which can be used to measure customer satisfaction, and the effect of these dimensions (tangibles, responsiveness, empathy, assurance, reliability, access, financial aspect, and employee competences) on customer satisfaction in Jordanian banks. Data were gathered from 825 customers in the Jordanian banking sector. The sample data were statistically analyzed through exploratory factor analysis by the SPSS program to determine service quality perception and customer satisfaction. The results illustrate that the modified SERVQUAL Model extracted four subscales in the new model instead of eight in the initial model. The first subscale contains four dimensions—assurance, reliability, access and employee competences. The second subscale consists of two dimensions—responsiveness and empathy. The third and fourth subscales—financial aspect and tangibility—are separate factors. Further studies should…

This paper researches decentralized data storage represented by blockchain technology and the possibility of its development in sustainable logistics and supply chain management. Although the benefits of blockchain technology have been most widely researched in the financial sector, major challenges in logistics, such as order delay, damage to goods, errors, and multiple data entry can also be minimized by introducing blockchain technology. This paper presents a comprehensive review of the current and rising trends of blockchain technology usage in logistics and supply chain management.

This study uses a Computable General Equilibrium model to analyze policy scenarios for a carbon tax on greenhouse gas emissions from petroleum fuels and kerosene in Ethiopia. The carbon tax starts at $5 per ton of carbon dioxide in 2018 and rises to $30 per ton in 2030; these rates are translated into taxes on the different energy types covered, depending on their carbon contents. Different scenarios examine the impacts with revenue recycling through a uniform sales tax reduction, reduction of labor income tax, reduction of business income tax, direct transfer back to households, and use by the government to reduce debt. Because petroleum fuels and kerosene are a relatively small part of the Ethiopian economy, the carbon tax has small impacts on overall economic activity and greenhouse gas emissions. In proportional terms, however, the impact on greenhouse gas emissions from these energy sources is notable, depending on the recycling scenario. The assumed carbon tax trajectory also can raise significant revenue—up to $800 million per year by 2030. The impacts on the poor through…

If we examine the characteristics of a sample of green bonds matched with their closest brown bond neighbors, we encounter a challenge. Green bonds have higher yields, lower variance, and are more liquid. The institutional/private issuer and the green third-party verification/non-verification breakdowns help explain this puzzle. Green bonds from institutional issuers have higher liquidity with respect to their brown bond correspondents and negative premia before correcting for their lower volatility. Green bonds from private issuers have much less favorable characteristics in terms of liquidity and volatility but have positive premia with respect to their brown correspondents, unless the private issuer commits to certify the “greenness” of the bond. An implication of our findings is that the issuer’s reputation or green third-party verifications are essential to reduce informational asymmetries, avoid suspicion of green (bond)-washing, and produce relatively more convenient financing conditions.

Sustainable development (SD) has become a fundamental strategy to guide the world’s social and economic transformation. However, in the process of practice, there are still misinterpretations in regards to the theory of SD. Such misinterpretations are highlighted in the struggle between strong and weak sustainable development paths, and the confusion of the concept of intra-generational and inter-generational justice. In this paper, the literature survey method, induction method, and normative analysis were adopted to clarify the gradual evolution and improvement process of the concept and objective of SD, to strengthen the comprehensive understanding of the SD theory. Moreover, we also tried to bring in the situation and concepts of China. The results show that the theory of SD has gone through three periods: the embryonic period (before 1972), the molding period (1972–1987), and the developing period (1987–present). SD is gradually implemented into a global action from the initial fuzzy concept, including increasing practical wisdom. The goal of SD evolves from pursuing the single…

The concept of “Industry 4.0” is expected to bring a multitude of benefits for industrial value creation. However, the associated risks hamper its implementation and lack a comprehensive overview. In response, the paper proposes a framework of risks in the context of Industry 4.0 that is related to the Triple Bottom Line of sustainability. The framework is developed from a literature review, as well as from 14 in-depth expert interviews. With respect to economic risks, the risks that are associated with high or false investments are outlined, as well as the threatened business models and increased competition from new market entrants. From an ecological perspective, the increased waste and energy consumption, as well as possible ecological risks related to the concept “lot size one”, are described. From a social perspective, the job losses, risks associated with organizational transformation, and employee requalification, as well as internal resistance, are among the aspects that are considered. Additionally, risks can be associated with technical risks, e.g., technical integration,…

The cement industry is facing numerous challenges in the 21st century due to depleting natural fuel resources, shortage of raw materials, exponentially increasing cement demand and climate linked environmental concerns. Every tonne of ordinary Portland cement (OPC) produced releases an equivalent amount of carbon dioxide to the atmosphere. In this regard, cement manufactured from locally available minerals and industrial wastes that can be blended with OPC as substitute, or full replacement with novel clinkers to reduce the energy requirements is strongly desirable. Reduction in energy consumption and carbon emissions during cement manufacturing can be achieved by introducing alternative cements. The potential of alternative cements as a replacement of conventional OPC can only be fully realized through detailed investigation of binder properties with modern technologies. Seven prominent alternative cement types are considered in this study and their current position compared to OPC has been discussed. The study provides a comprehensive analysis of options for future cements, and an…

This review provides a benchmark for future reviews of research on HESD, reveals the emerging…

Transformations towards sustainability are needed to address many of the earth’s profound environmental and social challenges. Yet, actions taken to deliberately shift social–ecological systems towards more sustainable trajectories can have substantial social impacts and exclude people from decision-making processes. The concept of just transformations makes explicit a need to consider social justice in the process of shifting towards sustainability. In this paper, we draw on the transformations, just transitions, and social justice literature to advance a pragmatic framing of just transformations that includes recognitional, procedural and distributional considerations. Decision-making processes to guide just transformations need to consider these three factors before, during and after the transformation period. We offer practical and methodological guidance to help navigate just transformations in environmental management and sustainability policies and practice. The framing of just transformations put forward here might be used to inform decision making in numerous marine and…

The world’s population continues to grow at a high rate, such that today’s population is twice that of 1960, and is projected to increase further to 9 billion by 2050. This situation has brought about a situation in which the percentage of the global energy used in cities is increasing considerably. Biomass is a resource that is present in a variety of different materials: wood, sawdust, straw, seed waste, manure, paper waste, household waste, wastewater, etc. Biomass resources have traditionally been used, and their use is becoming increasingly important due to their economic potential, as there are significant annual volumes of agricultural production, whose by-products can be used as a source of energy and are even being promoted as so-called energy crops, specifically for this purpose. The main objective of this work was to analyze the state of research and trends in biomass for renewable energy from 1978 to 2018 to help the research community understand the current situation and future trends, as well as the situation of countries in the international context, all of which…

Nowadays, it is better understood that the benefits of green infrastructure include a series of ecosystem services, such as cooling, water storage and management, recreation and landscaping, among others. Green technologies are still developing to provide sustainable solutions to the problems that modern cities and peri-urban areas face at an ever-increasing rate and intensity. Constructed wetlands technology is an established green multi-purpose option for water management and wastewater treatment, with numerous effectively proven applications around the world and multiple environmental and economic advantages. These systems can function as water treatment plants, habitat creation sites, urban wildlife refuges, recreational or educational facilities, landscape engineering and ecological art areas. The aim of this article is to highlight the synergies between this green technology and urban areas in order to reconnect cities with nature, to promote circularity in the urban context and to apply innovative wetland designs as landscape infrastructure and water treatment solutions. This…

The aim of the paper is to examine the long-term relationship between economic complexity, energy consumption structure, and greenhouse gas emission, within a panel of European Union countries and two subpanels: (i) European economies with higher economic complexity and (ii) European economies with a lower level of economic complexity. Taking into consideration the heterogeneity among European countries, the heterogeneous panel technique is used, including panel estimation through fully modified least squares (FMOLS) and dynamic ordinary least squares (DOLS). The empirical findings indicate a long-term equilibrium relationship between economic complexity, energy consumption structure and greenhouse gas emission within all three panels. Economic complexity and energy consumption structure have a statistically significant impact on greenhouse gas emission within all panels, but the influence is higher within the subpanel of countries with a lower level of economic complexity, suggesting a higher risk of pollution as the economic complexity grows and as the energy balance inclines in…

The acceleration of ecological crises has driven a growing body of thinking on sustainability transitions. Agroecology is being promoted as an approach that can address multiple crises in the food system while addressing climate change and contributing to the Sustainable Development Goals. Beyond the more technical definition as, “the ecology of food systems”, agroecology has a fundamentally political dimension. It is based on an aspiration towards autonomy or the agency of networks of producers and citizens to self-organize for sustainability and social justice. In this article, we use the multi-level perspective (MLP) to examine agroecology transformations. Although the MLP has been helpful in conceptualizing historic transitions, there is a need to better understand: (a) the role of and potential to self-organize in the context of power in the dominant regime, and (b) how to shift to bottom-up forms of governance—a weak point in the literature. Our review analyzes the enabling and disabling conditions that shape agroecology transformations and the ability of communities to…

In the postmodern era of industrialization, sustainable business performance is vital for success in a competitive environment. In order to attain sustainable business performance, Malaysian Small and Medium-sized Enterprises (SMEs) are facing various social and technological challenges. The objective of this study was to examine the roles of social and technological challenges in achieving a sustainable competitive advantage and sustainable business performance. To accomplish this objective, first-hand data were collected from Malaysian SMEs. Opinions of managerial staff of these SMEs were preferred regarding the roles of social and technological challenges in achieving a sustainable competitive advantage and sustainable business performance. An email survey was carried out to collect data. A total of 500 questionnaires were distributed among managerial staff of SMEs. Questionnaires were distributed by using simple random sampling. By using structural equation modeling, findings of the study revealed that social and technological challenges played major roles in boosting…

Overtourism is an emerging concept facing the world’s main tourist destinations. The growth that tourism has undergone in recent decades is of two different types. On the one hand, the development of new technologies and the creation of low-cost airline carriers have increased tourism levels, leading to growth even in emerging economies. On the other hand, uncontrolled demand alongside a concentration of tourism in particular destinations impact negatively both territories and local communities. The problems caused in some destinations by the increasing, ongoing growth in tourism have created the issue of “overtourism,” which is assuming an increasing significance in the literature. This paper contributes to the literature by providing an exploratory study with which to better understand the origins of overtourism, its implications, and predicted future perspectives in respect to the issue. Examination of the new evidence presented here contributes to the expanding knowledge of particular problems of tourism development.

This research paper focuses on a water quality prediction model which requires high-quality data. In the process of construction and operation of smart water quality monitoring systems based on Internet of Things (IoT), more and more big data are produced at a high speed, which has made water quality data complicated. Taking advantage of the good performance of long short-term memory (LSTM) deep neural networks in time-series prediction, a drinking-water quality model was designed and established to predict water quality big data with the help of the advanced deep learning (DL) theory in this paper. The drinking-water quality data measured by the automatic water quality monitoring station of Guazhou Water Source of the Yangtze River in Yangzhou were utilized to analyze the water quality parameters in detail, and the prediction model was trained and tested with monitoring data from January 2016 to June 2018. The results of the study indicate that the predicted values of the model and the actual values were in good agreement and accurately revealed the future developing trend of water…

The sol-gel technique has many advantages over the other mechanism for synthesizing metal oxide nanoparticles such as being simple, cheap and having low temperature and pressure. Utilization of waste materials as a precursor for synthesis makes the whole process cheaper, green and sustainable. Calcium Oxide nanoparticles have been synthesized from eggshell through the sol-gel method. Raw eggshell was dissolved by HCl to form CaCl2 solution, adding NaOH to the solution dropwise to agitate Ca (OH)2 gel and finally drying the gel at 900 °C for 1 h. The synthesized nanoparticle was characterized by scanning electron microscope (SEM), Fourier-transform infrared spectroscopy (FTIR), X-Ray fluorescence (XRF) and X-ray diffraction (XRD). The FTIR and XRD results have clearly depicted the synthesis of calcium oxide from eggshell, which is mainly composed of calcium carbonate. The FE-SEM images of calcium oxide nanoparticles showed that the particles were almost spherical in morphology. The particle size of the nanoparticles was in the range 50 nm–198 nm. Therefore, waste eggshell can be…

Tourism represents one of the main industries in terms of job creation and economic development while sustainability in tourism represents a worldwide challenge. The objective of the present study is to use a bibliometric approach to review the relevant literature. Bibliometric indicators, such as citations, are used to identify the field structure and the VOSviewer software is used to map the main trends in this area. Over the period 1987–2018, a total of 4647 papers were found in Scopus regarding sustainability issues in tourism. Analysis of the leading journals, authors, institutions, and keywords indicates that: (1) the literature on sustainability issues in the field of tourism is significantly growing; (2) a mere six papers accounted more than 300 citations, but there are several prolific authors; (3) of the 614 sources included in the review, the most important have published 46.7% of the papers; (4) in terms of documents and citations, the United States is the leading country in this topic; (5) according to keyword trend network analysis, sustainability is becoming a…

The choice of activating agent for the thermochemical production of high-grade activated carbon (AC) from agricultural residues and wastes, such as feedstock, requires innovative methods. Overcoming energy losses, and using the best techniques to minimise secondary contamination and improve adsorptivity, are critical. Here, we review the importance and influence of activating agents on agricultural waste: how they react and compare conventional and microwave processes. In particular, adsorbent pore characteristics, surface chemistry interactions and production modes were compared with traditional methods. It was concluded that there are no best activating agents; rather, each agent reacts uniquely with a precursor, and the optimum choice depends on the target adsorbent. Natural chemicals can also be as effective as inorganic activating agents, and offer the advantages that they are usually safe, and readily available. The use of a microwave, as an innovative pyrolysis approach, can enhance the activation process within a duration of 1–4 h and temperature of 500–1200 °C, after which…

The 17 Sustainable Development Goals (SDGs) of the 2030 Agenda, and their 169 targets, are interdependent and interlinked. The successful implementation of all SDGs will rely upon disentangling complex interactions between the goals and their targets. This implies that implementing the SDGs requires cross-sectoral processes to foster policy coherence. Over recent years, academic research has produced a number of different proposals for categorizing the SDGs, systematically mapping the linkages between them, and identifying the nature of their interdependencies. The aim of this review article is to provide ideas of how to move from generic appraisals of SDG interdependencies towards translating these interdependencies into policy action. To do so, the article first provides an overview of existing frameworks for the systematic conceptualization of the SDGs and the interlinkages and interdependencies between them. Secondly, the article critically discusses advantages and limitations of these frameworks, with a particular focus on methodological weaknesses, practical applicability to…

The promotion of pro-environmental behavior is regarded as very important in solving environmental problems. The Value-Belief-Norm (VBN) theory usually emphasizes internal factors; however, we have transformed this theory by including the environmental knowledge as an external factor. The results showed that action-related environmental knowledge was related to the ecological worldview and directly influenced the private sphere behavior. The ecological worldview, which in this paper was operationalized as environmental concern, had a direct effect on public sphere behavior and an indirect effect on private behavior through awareness of behavioral consequences. Thus, in this paper we revealed how specific environmental knowledge influenced pro-environmental behavior. We also suggest that it is important to educate people about local and global environmental problems, about the impact of behavior on the environment not only in private but also in the public sphere, and to foster the ecocentrism, as well. In addition, we revealed the meaning and necessity of education for environmental…

This study empirically analyzes an extended Unified Theory of Acceptance and Use of Technology 2 (UTAUT2) model that augments information quality to identify the determinants of continuous use intention for food delivery software applications. A sample survey of 340 respondents who had ordered or purchased food through delivery apps was used for the analysis. The results indicate that habit had the strongest influence on continuous use intention, followed by performance expectancy and social influence. Furthermore, information quality had an indirect effect on continuous use intention via performance expectancy. Consequently, this study confirms the importance of information quality, performance expectancy, habit, and social influence as factors in inducing users’ continuous use intention for food delivery apps. These findings expand previous research in online-to-offline business in the field of food services and suggest practical implications. Ultimately, the model proposed and validated in this study may be employed as a basis for future research on consumer behavior in the field…

Along with the acceleration of green marketing in recent years, greenwash has been utilized by firms to get ahead of their rivals. Underpinned by the cognition–affect–behavior (C-A-B) paradigm, this study examines a model linking greenwash and green skepticism with green purchase intentions. It also investigates the moderating role of information and knowledge on the relationship between greenwash and green purchase intentions. Data were obtained from 419 Vietnamese consumers who had been involved in purchasing green vegetables using an online survey. Multivariate data analysis demonstrated that greenwash was negatively associated with green purchase intentions and that green skepticism mediated this negative association. In addition, the moderating effect of information and knowledge was confirmed. These findings enrich the extant knowledge on the relationship between greenwash and green purchase intentions. They also have important implications for firms that aim to reduce consumers’ skepticism and increase their intentions to purchase green food.

Declining biodiversity (BD) is aecting food security, agricultural sustainability,and environmental quality. Agroforestry (AF) is recognized as a possible partial solution forBD conservation and improvement. This manuscript uses published peer-reviewed manuscripts,reviews, meta-analysis, and federal and state agency documents to evaluate relationships betweenAF and BD and how AF can be used to conserve BD. The review revealed that floral, faunal, and soilmicrobial diversity were significantly greater in AF as compared to monocropping, adjacent croplands, and within crop alleys and some forests. Among the soil organisms, arbuscular mycorrhizaefungi (AMF), bacteria, and enzyme activities were significantly greater in AF than crop and livestockpractices. Agroforestry also creates spatially concentrated high-density BD near trees due to favorablesoil-plant-water-microclimate conditions. The greater BD was attributed to heterogeneous vegetation,organic carbon, microclimate, soil conditions, and spatial distribution of trees. Dierences in BDbetween AF and other management types diminished…

The sustainability of rural development, both economic and environmental, has been increasingly linking to local food, which plays an indispensable role by preserving traditional culture, attracting tourists, and supporting the regional economy. However, the authenticity and quality of local food have not been fully convinced as competitive advantages by most practitioners. Little is known about how authenticity affects quality attributes, tourist satisfaction, and tourist loyalty. Thus, this study examines the role of authenticity in the quality–satisfaction–loyalty framework. The field research was performed in Shunde County, Guangdong Province, China. The results challenge the traditional view of quality attributes by highlighting that authenticity is a key antecedent to the quality–satisfaction–loyalty framework of food tourism. In contrast, the relationships among quality attributes, tourist satisfaction, and tourist loyalty are contingent on the extent to which food tourists perceive the authenticity of rural local food.

Entrepreneurs bring an enormous contribution to a country’s economic growth. Developing individual’s interest into new venture creation represents an important asset, especially for less developed countries where entrepreneurial activities are fundamental in enhancing economic growth. The recent economic crisis turned the attention of European policymakers towards entrepreneurship as a driving force for the creation of new job opportunities, regional/national competitiveness and growth. The aim of this article is to verify what relations are between locus of control, need for achievement and entrepreneurial intention of youth, following a cognitive approach and how much entrepreneurial education consolidates entrepreneurial skills and informs the young that entrepreneurship is a career option. To analyse entrepreneurial intentions, locus of control, need for achievement and entrepreneurial education in the context of Romania, this research used a quantitative design based on the answers to the questionnaire conducted during March 2017 to October 2017 on a sample of 270 students from…

Both UN Agenda 2030 and the Directive n. 2014/95/EU have recently promoted a marked improvement in sustainability disclosure, especially for larger companies or groups. Starting from this premise, we carried out an original study on the financial materiality of the E-S-G (environmental, social and governance) information of primary companies listed on major European indices in Belgium, France, Germany, Italy and Spain (BEL, CAC, DAX, FTSE-MIB, IBEX). Within the Stakeholder Theory and the Corporate Social Responsibility (CSR)–Corporate Social Perfomance (CSP) framework, our empirical analysis examined the impact of non-financial results (assessed through sustainability indicators) on economic (financial and market) performance in the timespan 2014–2017. We propose a different approach from previous studies, based on a PLS (Partial least squares)/SEM (Structural equation modeling) methodology together with the unprecedented consideration of “ESG” measures (Environmental, Social and Governance), either absolute (scores) or relative (extra-performance over industry sector). We find…

This paper explores how sustainability can be achieved through open innovation in the current 4th industrial revolution. Through a literature and practice review, we identify micro- and macro-dynamics of open innovation in addition to the dynamic roles of industry, government, university, and society. In particular, the industry continuously adopts open platforms to create and maintain ecosystem innovation. The government’s role has changed from regulation control toward facilitation. Universities have become proactively engaged in multiple areas, from technology transfer to knowledge co-creation. Societies and customers have started to form new concepts, R&D, and commercialization, resulting in a shared economy. Based on the analysis, we propose a conceptual framework to understand open innovation micro- and macro-dynamics with a quadruple-helix model for social, environmental, economic, cultural, policy, and knowledge sustainability. Furthermore, this provides an overview of the special issue, “Sustainability of Economy, Society, and Environment in the 4th Industrial Revolution”,…

Urban water systems and, in particular, wastewater treatment facilities are among the major energy consumers at municipal level worldwide. Estimates indicate that on average these facilities alone may require about 1% to 3% of the total electric energy output of a country, representing a significant fraction of municipal energy bills. Specific power consumption of state-of-the-art facilities should range between 20 and 45 kWh per population-equivalent served, per year, even though older plants may have even higher demands. This figure does not include wastewater conveyance (pumping) and residues post-processing. On the other hand, wastewater and its byproducts contain energy in different forms: chemical, thermal and potential. Until very recently, the only form of energy recovery from most facilities consisted of anaerobic post-digestion of process residuals (waste sludge), by which chemical energy methane is obtained as biogas, in amounts generally sufficient to cover about half of plant requirements. Implementation of new technologies may allow more efficient strategies of energy…

There has been considerable progress in the incorporation of sustainable development (SD) into higher education institutions’ curricula. This has included research on competences for SD and pedagogical approaches used; however, there has been limited research on the connection between how pedagogical approaches are used and how they may develop sustainability competences. A survey was developed, based on the ‘connecting sustainable development pedagogical approaches to competences’ framework, to investigate sustainability being taught, sustainability competences developed, and pedagogical approaches used in European higher education institutions. The survey was sent to a database of more than 4000 contacts from which 390 complete responses (9.80%) were obtained. The results show that the social dimension was the least addressed at 18% of responses, while the economic, environmental, and cross-cutting dimensions were addressed almost equally. The correlation analyses showed a relation between the contribution to sustainability and the strength of competences, and between the strength…

The demand for renewable energy sources worldwide has gained tremendous research attention over the past decades. Technologies such as wind and solar have been widely researched and reported in the literature. However, economical use of these technologies has not been widespread due partly to cost and the inability for service during of-source periods. To make these technologies more competitive, research into energy storage systems has intensified over the last few decades. The idea is to devise an energy storage system that allows for storage of electricity during lean hours at a relatively cheaper value and delivery later. Energy storage and delivery technologies such as supercapacitors can store and deliver energy at a very fast rate, offering high current in a short duration. The past decade has witnessed a rapid growth in research and development in supercapacitor technology. Several electrochemical properties of the electrode material and electrolyte have been reported in the literature. Supercapacitor electrode materials such as carbon and carbon-based materials have…

The topic of engagement has been attracting increasing amounts of attention in the field of e-learning. Research shows that multifarious benefits occur when students are engaged in their own learning, including increased motivation and achievement. Previous studies have proposed many scales for measuring student engagement. However, very few have been developed to measure engagement in e-learning environments. Thus, developing an instrument for measuring student engagement in e-learning environments is the purpose of this study. The participants of this study were 737 Korean online university students. Initial items were designed based on the literature. The instrument items were reduced from an initial 48 to 24 items after obtaining expert opinion and then validity and reliability analysis. Exploratory and confirmatory factor analyses were also conducted. Six factors, including psychological motivation, peer collaboration, cognitive problem solving, interaction with instructors, community support, and learning management emerged in the 24-item scale. This scale is expected to help…

In order to reduce vehicle emitted greenhouse gases (GHGs) on a global scale, the scope of consideration should be expanded to include the manufacturing, fuel extraction, refinement, power generation, and end-of-life phases of a vehicle, in addition to the actual operational phase. In this paper, the CO2 emissions of conventional gasoline and diesel internal combustion engine vehicles (ICV) were compared with mainstream alternative powertrain technologies, namely battery electric vehicles (BEV), using life-cycle assessment (LCA). In most of the current studies, CO2 emissions were calculated assuming that the region where the vehicles were used, the lifetime driving distance in that region and the CO2 emission from the battery production were fixed. However, in this paper, the life cycle CO2 emissions in each region were calculated taking into consideration the vehicle’s lifetime driving distance in each region and the deviations in CO2 emissions for battery production. For this paper, the US, European Union (EU), Japan, China, and Australia were selected as the reference regions for…

This paper examines the adoption of mobile applications for restaurant searches and/or reservations (MARSR) by users, as part of their experiential quality. Following an extended and expanded version of UTAUT-2, this research proposes eight determinants of intentions to use: performance expectancy, effort expectancy, facilitating conditions, hedonic motivation, price-saving orientation, habit, social influence, and perceived credibility. The data were collected from Spanish users of MARSR applications (n = 1200), and analyzed using structural equation modeling (SEM). The findings confirm the need to extend and expand UTAUT-2 by incorporating perceived credibility and the social norm approach. The results gathered from SEM indicate that the drivers of intentions to use MARSR are, in order of impact: habit, perceived credibility, hedonic motivation, price-saving orientation, effort expectancy, performance expectancy, social influence, and facilitating conditions. Habit, facilitating conditions, and intentions to use are significantly related to use. Additionally, the moderating…

The circular economy has been heralded as a potential driver for sustainable development by business, academia, and policymakers. In a future circular economy, new business models are needed that slow, close and narrow resource loops to address key resource and climate challenges. After a phase of excitement and inspiration, an operationalization phase needs to start to ensure the best possible implementation and transition towards a circular economy. This operationalization phase will involve the development of products, processes and business models that significantly lower the negative impact on the environment, reduce waste and resource pressures and, rather, create a positive impact on society and environment. This paper focuses on the circular business model lens as a comprehensive way of addressing business innovation. Within this evolving circular economy operationalization phase, several tools, approaches and methods are emerging that could support circular business model innovation. This paper seeks to create a comprehensive tools overview through a literature and practice…

Role of the knowledge-based resources in promoting sustainability in small and medium enterprises (SMEs) is currently a topic of debate. Financial literacy has been identified as a vital knowledge resource for financial decision making, but insufficient attention has been given to how SMEs’ financial literacy affects their sustainability. Drawing upon a knowledge-based perspective, peaking order theory and dual process theory, we constructed an integrated model to examine the impact of financial literacy, access to finance and financial risk attitude on SMEs’ sustainability. The sample included 291 chief financial officers (CFOs) of SMEs in Sri Lanka. The output of structural equation modelling revealed direct positive effects of financial literacy, access to finance and financial risk attitude on sustainability. Financial literacy also emerged as a predictor of access to finance and financial risk attitude. Moreover, access to finance and financial risk attitude were found to be partial mediators of the relationship between financial literacy and SMEs’ sustainability. Theoretical…

The management of solid waste presents a challenge for developing countries as the generation of waste is increasing at a rapid and alarming rate. Much awareness towards the sustainability and technological advances for solid waste management has been implemented to reduce the generation of unnecessary waste. The recycling of this waste is being applied to produce valuable organic matter, which can be used as fertilizers or amendments to improve the soil structure. This review studies the sustainable transformation of various types of biomass waste such as animal manure, sewage sludge, municipal solid waste, and food waste, into organic fertilizers and their impact on waste minimization and agricultural enhancement. The side effects of these organic fertilizers towards the soil are evaluated as the characteristics of these fertilizers will differ depending on the types of waste used, in addition to the varying chemical composition of the organic fertilizers. This work will provide an insight to the potential management of biomass waste to be produced into organic fertilizer and the…

Financial development has been deemed to be an important factor influencing carbon emissions; however, the specific effect generated by financial development is still disputed. In this study, we examined the relationship between financial development and carbon emissions based on a system generalized method of moments and the data of 155 countries, and we further analyzed the national differences by dividing the sample countries into two sub-groups: developed countries, and emerging market and developing countries. The empirical results indicated that from a global perspective, financial development could significantly increase carbon emissions, and the analysis of the emerging market and developing countries reached the same conclusion; however, the results indicated that for developed countries, the effect of financial development on carbon emissions is insignificant. A series of robustness checks were conducted and confirmed that our empirical results were reliable. We suggest that policymakers in emerging market and developing countries should carefully balance financial…

Although the rapid progress of the global economy and technology has advanced human civilization, it has also caused tremendous damage to the global ecological environment. Therefore, humans are thinking seriously about the environment and its sustainable development. One of the solutions to environmental problems is new energy vehicles. Since the promulgation of the “Energy Saving and New Energy Vehicle Industry Development Plan (2012–2020)” by the General Office of the State Council, the Chinese government has determined a strategy of pure electric driving technology. The electric vehicle market in China has expanded rapidly, making China the largest electric vehicle market in the world. Hence, research on the situation of electric vehicles in China is highly necessary and of reference value for other countries to develop electric vehicles. As a result, it is a critical issue to develop low-carbon, energy-saving, and intelligent electric vehicles to reduce the environmental impact. This paper establishes a theoretical framework based on the theory of planned behavior (TPB),…

The food that we consume has a large impact on our environment. The impact varies significantly between different diets. The aim of this systematic review is to address the question: Which diet has the least environmental impact on our planet? A comparison of a vegan, vegetarian and omnivorous diets. This systematic review is based on 16 studies and 18 reviews. The included studies were selected by focusing directly on environmental impacts of human diets. Four electronic bibliographic databases, PubMed, Medline, Scopus and Web of Science were used to conduct a systematic literature search based on fixed inclusion and exclusion criteria. The durations of the studies ranged from 7 days to 27 years. Most were carried out in the US or Europe. Results from our review suggest that the vegan diet is the optimal diet for the environment because, out of all the compared diets, its production results in the lowest level of GHG emissions. Additionally, the reviewed studies indicate the possibility of achieving the same environmental impact as that of the vegan diet, without excluding the meat…

The main objective of this research was to examine how transformational leaders boost their followers’ innovative work behavior through trust in a leader, empowerment, and work engagement. Data were collected from 281 multinational organization employees in China. The Statistical Package for the Social Sciences (SPSS) macro process was utilized to test the proposed hypothesis. The findings revealed that transformational leadership and work engagement were significantly related to innovative work behavior. The findings also demonstrated the significant impact of transformational leadership on trust in a leader, and its subsequent positive impact on the work engagement of the employees. Furthermore, the results supported a significant serial mediation between transformational leadership, trust, work engagement, and employees’ innovative behavior. The results also showed a significant moderating effect of empowerment on transformational leadership and innovative work behavior. For boosting employees’ innovative work behavior, leaders in the organization should strive to engage them…

Social entrepreneurship has been recognized as a tool to attain sustainable development. This paper highlights the role of social entrepreneurship in triggering social change and attaining sustainable development. The paper contributes significantly to the existing literature by conducting a systematic review of extant works. To this end, we analyzed and reviewed 173 research papers from the Web of Science database. The results are presented in the form of descriptive findings and thematic discussion. The paper concludes by setting up the agenda for future researchers in the field.

The issues concerning the management of sewage sludge produced in wastewater treatment plants are becoming more important in Europe due to: (i) the modification of sludge quality (biological and chemical sludge are often mixed with negative impacts on sludge management, especially for land application); (ii) the evolution of legislation (landfill disposal is banned in many European countries); and (iii) the technologies for energy and material recovery from sludge not being fully applied in all European Member States. Furthermore, Directive 2018/851/EC introduced the waste hierarchy that involved a new strategy with the prevention in waste production and the minimization of landfill disposal. In this context, biological sewage sludge can be treated in order to produce more stabilized residues: the biosolids. In some European countries, the reuse of biosolids as soil improver/fertilizer in arable crops represents the most used option. In order to control the quality of biosolids used for land application, every Member State has issued a national regulation based on the European…

The current study focuses on understanding the factors (subjective norms (SNs), personal attitude, and perceived behaviour control (PBC)) that influence consumer purchase intention regarding organic food from the theory of planned behaviour and health consciousness as an additional factor in Tanzania and Kenya. It further explains the role of knowledge as a moderating variable in organic food purchase intention. A total of 331 responses from Tanzania and 350 responses from Kenya were obtained. Confirmatory factor analysis was applied for validation, and results were analysed using structural equation modeling. SNs, personal attitudes, and health consciousness were found to be significant predictors of organic purchase intention in both countries. Furthermore, findings show that knowledge positively moderates the relationship among SNs, personal attitude, health consciousness, and organic food purchase intention. However, PBC was found to be a weak influencer on consumer purchase intention in Kenya, and no knowledge interaction between PBC and consumer purchase intention in Tanzania…

Since 2018, pedestrians in many U.S. cities have been sharing sidewalk space with dockless shared e-scooters. The introduction of e-scooters has received pushback from pedestrians. Complaints reported in the media include e-scooters blocking walkways and sidewalks when parked illegally as well as safety concerns from pedestrians who do not feel safe around moving e-scooters. However, little is known beyond a few initial studies on e-scooter parking and anecdotes about pedestrian perceptions of e-scooter safety. Our case study from Rosslyn, Virginia, helps shed light on these two issues. First, we conducted a survey of 181 e-scooter riders and non-riders asking about their perceived safety around riders of e-scooters and experiences of sidewalks blocked by e-scooters. We found highly divergent responses about safety and sidewalk blocking perceptions from riders and non-riders. Second, we conducted an observational study of 606 parked e-scooters along three mixed-use corridors in Rosslyn to investigate the relationship between the built environment and e-scooter parking. We found that…

The production and distribution of food are among the hot topics debated in the context of sustainable development. Short food supply chains (SFSCs) are now widely believed to be more sustainable in comparison to mass food delivery systems. To date, very little quantitative evidence exists on the impacts of various types of food supply chains. Using a cross-sectional quantitative approach, this study assesses the sustainability of distribution channels in short and long food supply chains based on 208 food producers across seven countries: France, Hungary, Italy, Norway, Poland, the United Kingdom, and Vietnam. Ten distribution channel types are used in this study. To provide a comprehensive sustainability assessment, a set of economic, social, and environmental indicators are applied. Indicators commonly used in the literature are used, supported by original indicators constructed specifically for the present study. In total, 486 chains are examined and the study confirms that individual producers participate simultaneously in several, short and long chains. Participation in SFSCs…

The role of sustainability dimensions in the value creation process has attracted considerable interest in the scientific academic world in the last two decades. The 2030 Agenda, which fixed the sustainable goals (SDGs) to safeguard our planet, highlighted the fundamental role of sustainability issues. In this context, companies around the world need to integrate their strategies with environmental, social, and economic dimensions. However, sustainability aspects are often not linked to company strategies, and there has been growing difficulty in measuring sustainable development by adopting an appropriate set of key performance indicators (KPIs). Accordingly, the aim of this study is as follows: (1) to identify the suitable KPIs that affect company performance, based on the literature and management practices, and (2) to propose a new perspective on a way to integrate sustainability issues in company strategies. Based on a systematic procedure, we obtained 82 papers that focus on KPIs related to sustainability issues. Following a review of papers and a survey conducted with Italian…

Cow milk is under increased scrutiny due to its environmental impact and ethical considerations concerning animal welfare. At the same time, a rising share of consumers is switching to plant-based milk substitutes (abbreviated “plant milk”). The objective of this study was (1) to analyze the product image of plant milk and cow milk and (2) to compare the motivational structure behind the consumption of both product categories. For this purpose, a quantitative survey with Austrian consumers was carried out to analyze the product image of plant milk in comparison to cow milk (n = 1001). The product image analysis revealed that the product image of cow milk is still much better than that of plant milk. Amongst others, cow milk is considered to be healthier, more natural, and better for bones. Product image valuation was dependent on the (non-)consumption of plant milk. Plant milk consumers evaluated plant milk significantly better; they considered plant milk to be much better digestible and allergy-free. The qualitative study using means-end-chain analysis, with two sub-samples of…

Reducing the use of non-renewable resources is a key strategy of a circular economy. Mycelium-based foams and sandwich composites are an emerging category of biocomposites relying on the valorization of lignocellulosic wastes and the natural growth of the living fungal organism. While growing, the fungus cements the substrate, which is partially replaced by the tenacious biomass of the fungus itself. The final product can be shaped to produce insulating panels, packaging materials, bricks or new-design objects. Only a few pioneer companies in the world retain a significant know-how, as well as the ability to provide the material characterization. Moreover, several technical details are not revealed due to industrial secrecy. According to the available literature, mycelium-based biocomposites show low density and good insulation properties, both related to acoustic and thermal aspects. Mechanical properties are apparently inferior in comparison to expanded polystyrene (EPS), which is the major synthetic competitor. Nevertheless, mycelium-based composites can display an enormous…

Floods are some of the most destructive and catastrophic disasters worldwide. Development of management plans needs a deep understanding of the likelihood and magnitude of future flood events. The purpose of this research was to estimate flash flood susceptibility in the Tafresh watershed, Iran, using five machine learning methods, i.e., alternating decision tree (ADT), functional tree (FT), kernel logistic regression (KLR), multilayer perceptron (MLP), and quadratic discriminant analysis (QDA). A geospatial database including 320 historical flood events was constructed and eight geo-environmental variables—elevation, slope, slope aspect, distance from rivers, average annual rainfall, land use, soil type, and lithology—were used as flood influencing factors. Based on a variety of performance metrics, it is revealed that the ADT method was dominant over the other methods. The FT method was ranked as the second-best method, followed by the KLR, MLP, and QDA. Given a few differences between the goodness-of-fit and prediction success of the methods, we concluded that all these five…

This Special Issue addresses the intersections of outdoor recreation, nature-based tourism, and sustainability. Outdoor recreation and nature-based tourism provide essential benefits to individuals, communities, and society and thereby contribute to sustainability. Equitable provision of opportunities, cultural variations in desired experiences, barriers to outdoor recreation, and diverse perceptions of both nature and recreation add to the complexity in outdoor recreation and nature-based tourism service delivery. Outdoor recreation and nature-based tourism occur within a socioecological system with feedback loops to changing social, economic, technological, and ecological conditions. On a global scale, climate change and other disturbance factors are impacting ecosystems and opportunities, increasing the importance of adaptation strategies for longer-term planning. Population growth and regional shifts in demographics and distribution (e.g., urbanization), as well as socioeconomic trends, affect who engages in outdoor recreation and nature-based tourism, opportunities sought,…

In a research community, data sharing is an essential step to gain maximum knowledge from the prior work. Existing data sharing platforms depend on trusted third party (TTP). Due to the involvement of TTP, such systems lack trust, transparency, security, and immutability. To overcome these issues, this paper proposed a blockchain-based secure data sharing platform by leveraging the benefits of interplanetary file system (IPFS). A meta data is uploaded to IPFS server by owner and then divided into n secret shares. The proposed scheme achieves security and access control by executing the access roles written in smart contract by owner. Users are first authenticated through RSA signatures and then submit the requested amount as a price of digital content. After the successful delivery of data, the user is encouraged to register the reviews about data. These reviews are validated through Watson analyzer to filter out the fake reviews. The customers registering valid reviews are given incentives. In this way, maximum reviews are submitted against every file. In this scenario,…

This study explores the interaction between environmental consciousness and sustainable food attributes as predictors in the market segmentation process for sustainable foods with respect to United States (U.S.) Generation Z (Gen Z) consumers. This study was executed using a cross-national, web-based survey to analyze and categorize Gen Z female (n = 435) and male (n = 377) consumers between 18 and 23 years of age living in the continental United States. The objectives of this study were to classify U.S. Gen Z consumers into unique segments based on their environmental consciousness and to assess the functional relationships among the following: (a) their degree of ecological awareness; (b) the importance of the perception of sustainable food attributes; (c) their food choices associated with healthy eating habits; and (d) sociodemographics. Survey data were analyzed using cluster analysis of consumer groups based on environmental consciousness. Environmental consciousness was measured using a composite score of the environmental involvement scale and the environmental values scale.…

Environmental education and education for the environment today play an important role toward sustainability. Environmental education provided by higher education institutions has an important impact on training and preparing the future generation for a green society. The purpose of this study is to examine the relationship among perception, attitude, and environmental behavior of the university students enrolled in different specialization fields (engineering electrical, mechanical, and economic). A total of 358 students participated in this survey conducted at the North Center University of Baia Mare. To collect data to measure students’ environmental education, perception, students’ attitudes, and behavior a Likert scale was used. In this study, it was revealed that students receiving academic education are involved in activities regarding environmental protection (volunteer, warning, participation, recycling of materials) using the new product and “greener” alternative energy. As a result of the t-test performed, it was put forward that there was no difference in their level of…

Organizations have several objectives, including competitiveness, high profit and long-term survival. However, sustainability has become a diligent act of business and non-business organizations because it moves organizations toward superior performance. Sustainability does not come itself; it requires enough resources and capabilities. Extant studies have examined the factors that influence sustainability, but have rarely touched on innovation in this perspective. The present study examines the influence of management innovation and technological innovation on organization performance with the mediating role of sustainability. To test the model, we applied structural equation modeling in the analysis of a moment structures (AMOS) on the empirical evidence collected from 304 Pakistani CEOs and top managers. The results indicate that management innovation and technological innovation significantly positively contribute to sustainability and organization performance. Sustainability plays a partial mediating role between management innovation and organization performance and also a…

In order to consider green roofs as an environmentally friendly technology, the selection of efficient and sustainable components is extremely important. Previous review papers have mainly focused on the performance and advantages of green roofs. The objective of this paper is to examine the primary layers: The waterproof and anti-root membranes; the protection, filter, and drainage layers; the substrate; and the vegetation. First, the history, modern applications, benefits and classification are analyzed in order to present a well-defined state of the art of this technology. Then, the roles, requirements, characteristics, and materials are assessed for each green roof layers. This technology was compared to a conventional roof technology, Mediterranean climate conditions and their influence on green roof design were assessed, also comparing them with Tropical area and focusing on irrigation systems, examples about the commercial materials and products available in the market were provided and innovative materials coming from recycled sources were analyzed. Future research should…

Recycling and value-added utilization of agricultural residues through combining technologies such as anaerobic digestion and pyrolysis could double the recoverable energy, close the nutrient recycle loop, and ensure cleaner agricultural production. This study assessed the beneficial application of biochar to soil to recycle digestate nutrients, improve soil quality, and reduce conventional chemical fertilizer. The addition of digestate-enriched biochar improved soil quality as it provided higher soil organic matter (232%–514%) and macronutrients (110%–230%) as opposed to the unenriched biochar and control treatments. Maize grown in soil amended with digestate-enriched biochar showed a significantly higher biomass yield compared to the control and non-enriched biochar treatments but was slightly lower than yields from chemical fertilizer treatments. The slightly lower yield (20%–25%) achieved from digestate-enriched biochar was attributed to slower mineralization and release of the adsorbed nutrients in the short term. However, digestate-enriched biochar could in the long term…

As the world’s largest grain producer, China’s straw yield was 700 million tonnes in 2014. With a national utilization rate of 80% in 2015, there is still a large amount of straw burned in open-field, resulting in air pollution and a reduction in the quantity available as a source of bioenergy. This paper conducts a literature review of success stories and major challenges in comprehensive straw utilization in and out of China. It is noted that nationwide long-term feasible and sustainable straw utilization at a high rate is a highly complex operation, involving most societal sectors, many people and facilities often at different regions. Scenarios were analyzed to estimate the energy potential and air emission reductions China would accomplish in 2020 by converting an additional 5 or 10% of straw-yield to biofuel. Currently, the approach to control straw burning in China is primarily administrative, relying heavily on prohibition and penalties, inconsistent across policy areas and geography, and lacking in long-term planning. Consequently, the effectiveness of the current approach…

Green human resource management (GHRM) in the environmental management of organizations has gradually become a key issue in academic circles, and its impact on employees’ green behavior has received increasing attention. However, few studies have explored its impact from the perspective of information delivery. Based on an analysis of the literature, this research discusses the influence route of five types of GHRM practices (employee life cycle, rewards, education and training, employee empowerment, and manager involvement) on employee green behavior in the workplace and the mediating effects of information needs based on the technology acceptance model. Using cross-sectional survey data from enterprises in the People’s Republic of China, the proposed theoretical model was tested and the results showed that employee life cycle, education and training, employee empowerment, and manager involvement all significantly affect the in-role and extra-role green behavior of employees positively, while rewards only significantly predict extra-role behaviors. Information need plays a…

Sustainability, as a key concept in the education field, has submitted a relevant change during the last years. Thus, there is a growing debate about its meaning. It has undergone a crucial merging of significances from many fields: Ecology, environmental awareness, but also from politics, ethics or even spiritual approaches. All these fields have been co-involved in the building of such subject concept. In this sense, this article addresses the different ways of understanding sustainability as a polyhedral concept and how sustainability can be understood under the umbrella of the Sustainable Development Goals (SDGs). Furthermore, it is proposed a conceptual framework to teach this UN Program at Higher Education, contributing to the training of undergraduate and postgraduate students from both a professional and a personal point of view. This framework is applied in a case study—in particular, in a course of Primary Teacher Degree called Didactics of Matter and Energy. This article finishes with practical consideration to build a change-maker University.

In recent years, the concept of hybrid energy systems (HESs) is drawing more attention for electrification of isolated or energy-deficient areas. When optimally designed, HESs prove to be more reliable and economical than single energy source systems. This study examines the feasibility of a combined dispatch (CD) control strategy for a photovoltaic (PV)/diesel/battery HES by combining the load following (LF) strategy and cycle charging (CC) strategy. HOMER software is used as a tool for optimization analysis by investigating the techno-economic and environmental performance of the proposed system under the LF strategy, CC strategy, and combined dispatch CD strategy. The simulation results reveal that the CD strategy has a net present cost (NPC) and cost of energy (COE) values of $110,191 and $0.21/kWh, which are 20.6% and 4.8% lower than those of systems utilizing the LF and CC strategies, respectively. From an environmental point of view, the CD strategy also offers the best performance, with CO2 emissions of 27,678 kg/year. Moreover, the results show that variations in critical…

Higher education is a principal agent for addressing the sustainable development goals proposed by the 2030 Agenda, because of its key mission of knowledge generation, teaching and social innovation for sustainability. In order to achieve this, higher education needs to integrate transversally the values of sustainability in the way of developing the field of management, as well as research, university life and, of course, teaching. This paper focuses on teaching, and more specifically on the didactic strategies considered most relevant for training in sustainability competencies in college students, according to the guidelines commonly accepted by the international academic community. Through collaborative work among experts from six Spanish universities taking part in the EDINSOST project (education and social innovation for sustainability), funded by the Spanish R&D+i Program, in this paper the role of five active learning strategies (service learning, problem-based learning, project-oriented learning, simulation games and case studies) in education for sustainability are…

Leadership style is an important factor that affects the enhancement of organizational performance and employee’s job performance, and what objectives they should pursue, which also makes a profit for their employees or makes another social and economic contribution to society. The present study was developed to observe the impact of transformational leadership on job performance and to investigate the mediating mechanism of corporate social responsibility (CSR). Primary data were collected from the employees by using a cross-sectional design method. Employees who participated in the study are working in the Small and Medium Enterprises (SMEs) of Pakistan. A total of 300 questionnaires were circulated, and 130 were received. The Regression analysis was executed to examine whether CSR mediated the correlation among transformational leadership and job performance. The results of the study suggest that transformational leadership positively and completely predicts job performance. Particularly, the study finds that CSR significantly mediated the effect of transformational leadership on…

Previous environmental sustainability studies have examined only limited type of pro-environmental behaviour (PEB; e.g., recycling), but have not explored relationships among various types or dimensions of PEBs. This paper explores six types of PEBs (i.e., activist, avoider, green consumer, green passenger, recycler and utility saver) and investigates their antecedents and interrelationships between two ethnic groups—Malays and Chinese in Malaysia. Survey data from 581 respondents, comprising 307 Malays and 274 Chinese, were used to assess the research model. To conduct multi-group analysis, the study used partial least squares structural equation modelling in SmartPLS 3. The study extends the Value-Belief-Norm (VBN) theory by using social norms to predict PEBs. The results suggest that social norms predict each type of PEB, in contrast to other constructs in VBN theory, except for utility-saving behaviours. The findings also reveal some similarities as well as differences between Malays and Chinese, indicating that the two ethnic groups are not homogeneous. The study is the first…

The use of polymer-modified binders in asphalt mixtures has become more widespread due to their reduced thermal susceptibility and improved rutting and fatigue resistance. Nevertheless, their high cost limits their application, thus making the use of reclaimed polymers (RP) an interesting alternative for both reducing price and extending the service life of pavements. This paper; therefore, presents a comparative review of the recycled polymers most commonly studied as bitumen modifiers: polyethylene (PE), polypropylene (PP), polyvinyl chloride (PVC), ethyl vinyl acetate (EVA), and ground tire rubber (GTR), in order to facilitate their selection and extend the use of the bitumen. The differences in terms of melting point, mixing conditions, and maximum quantity of added polymer are analyzed. Moreover, their effect on the mechanical behavior of the asphalt binders and their stability with and without the use of additives is presented. According to the literature revision, the performance of the new binder is more influenced by the kind of polymer that was incorporated and the mixing…

With benefits to both human well-being and pro-nature conservation behaviors, nature connectedness is emerging as an important psychological construct for a sustainable future. The growing research and applied and policy-related interests require a straightforward measure of nature connectedness that is suitable for both children and adult populations. To establish the reliability of the new Nature Connection Index (NCI) three factor analyses were conducted. One was based on a large Monitor of Engagement with the Natural Environment (MENE) dataset for adults (n = 3568) with a replication from data sets collected online (n = 553), and a third used MENE data from children (n = 351). To validate the NCI as a measure for nature connectedness an online comparison study (n = 153) included the NCI alongside other established measures. The results showed that the NCI was a reliable and valid scale that offers a short, simple alternative to other measures of nature connectedness, particularly for populations including both children and adults, measured face to face or online. The utility of…

Academic institutions like other business organizations strive to achieve, maintain, and sustain their competitive advantages. In this study, we examined the influence of the “strategic human resources management (HRM) practices” on the achievement of “competitive advantages” that will be sustainable, with an evaluation of the mediating role of “human capital” development, and the commitment of employees in an academic environment. Six hundred questionnaires were randomly distributed to the employees of selected universities in Erbil City of Iraq. Structural equation modeling (SEM) techniques were employed for the analysis with the use of Smart Partial Least Square PLS. Findings from our study revealed a linear and positive influence of the strategic HRM on the sustainability of “competitive advantages”; strategic HRM was also found to positively influence human capital development and the commitment of employees to the institutions; the influence of both human capital development and employees’ commitment were found to have a partial mediation in the strategic HRM practices and…

The aim of the paper is to apply the Environmental Kuznets Curve (EKC) model in order to explore the link between economic complexity index (ECI) and carbon emissions, in 25 selected European Union (EU) countries from 1995–2017. The study examines a cointegrating polynomial regression (CPR) for a panel data framework as well as for simple time series of individual countries. In the model is also included the variable ‘energy intensity’ as main determinant of carbon emissions. Depending on economic complexity, the CO2 emissions pattern was found to exhibit an inverted U-shaped curve: in the initial phase, pollution increases when countries augment the complexity of the products they export using and after a turning point the rise of economic complexity suppress the pollutant emissions. The panel cointegration test indicates a long-run relationship between economic complexity, energy intensity and carbon emissions. It was also found that a rise of 10% of energy intensity would lead to a 3.9% increase in CO2 emissions. The quadratic model incorporating ECI is validated for the whole…

Land use and land cover (LULC) form a baseline thematic map for monitoring, resource management, and planning activities and facilitate the development of strategies to balance conservation, conflicting uses, and development pressures. In this study, changes in LULC in North Sumatra, Indonesia, are simulated and predicted using an artificial-neural-network-based cellular automaton (ANN-CA) model. Five criteria (altitude, slope, aspect, distance from the road, and soil type) are used as exploratory data in the learning process of the ANN-CA model to determine their impacts on LULC changes between 1990 and 2000; among the criteria, altitude and distance from the road have strong impacts. Comparison between the predicted and the real LULC maps for 2010 illustrates high agreement, with a Kappa index of 0.83 and a percentage of correctness of 87.28%. Then, the ANN-CA model is applied to predict LULC changes in 2050 and 2070. The LULC predictions for 2050 and 2070 demonstrate high increases in plantation area of more than 4%. Meanwhile, forest and crop area are projected to decrease by…

We investigate why companies collaborate within the circular oriented innovation process. The purpose is to understand what motives trigger collaborative circular oriented innovation, as well as conditions, drivers and barriers. First, we define circular oriented innovation building on sustainable oriented innovation literature. Subsequently, we investigate 11 leading circular economy companies operating within the Netherlands, who developed collaborative circular oriented innovation activities. ‘Hard’ and ‘soft’ dimensions for innovation are identified and applied to delineate the drivers and barriers for collaborative circular oriented innovation. Our findings indicate that collaborations are conducted by entrepreneurially-minded actors through sharing a vision, enthusiasm, and crucially, a credible proposition for a circular economy. Furthermore, collaboration is sought early, to co-develop the problem and solution space and integrate disparate knowledge from across the value network, to mitigate increased complexity. Motives to collaborate vary between personal and…

Rapid growth in construction activities as a result of a growing population and urbanization in many parts of the world generates a large amount of waste from construction. To reduce and manage these wastes, a comprehensive understanding of the construction waste generation factors is needed. The purpose of this study is to identify the contributing factors of construction waste in Thailand’s construction industry. The causes of construction waste were identified through an extensive literature review. A total of 28 causes of construction waste were identified and grouped into the four categories: design and documentation, material and procurement, construction method and planning, and human resources. To determine the significant level of each factor, a structured questionnaire survey was carried out to gather information from contractors about causes of construction material waste. The results show that the categories contributing to construction waste ranks as design and documentation, human resources, construction methods and planning, and material and procurement, respectively.…

The Sustainable Development Goals (SDGs) constitute a working agenda for the international community with the aim of ensuring a better world for future generations. In this context, the development of competences related to SDGs is a challenge for Higher Education Institutions. Although there are several studies that address the relationship between SDGs and university teaching, the students’ knowledge about this subject has not been set out yet. In order to evaluate students’ knowledge, a questionnaire was designed, validated, and administered to students from different degrees. Statistical analysis showed a high reliability for the constructs (Smallest Cronbach’s Alfa = 0.859). The results showed interesting insights, either with descriptive analysis or inferential ones. For example, a low knowledge, in a general way, of SDGs was identified in the whole sample; significant differences between the scores obtained in professional and personal implications of SDGs were also detected and several differences arose between Health and Education students, the latter being more…

Cities can enhance their sustainability planning by prioritizing accessibility as a performance metric for transportation planning. In this context, accessibility measures the ease of reaching opportunities and captures more characteristics of sustainable cities than the more conventionally used mobility metrics, focusing on the overall ability to move and generally recommending faster speeds to overcome distance. However, how cities can prioritize accessibility in planning is understudied. This research presents a case of Tempe, Arizona, putting accessibility into practice through a 20-min lens. Using a 20-min threshold for all modes, the city aims to promote travel for daily activities that is less reliant on private autos. The analysis presented here documents the challenges that planners face when planning for accessibility. The challenges range from technical points to decisions that need to be made about the quality of the built environment. The analysis also shows that Tempe, which is a classically suburban city of wide roads and single-family homes that was built around the…

The multidisciplinary nature of a corporate social responsibility (CSR) committee reflects the commitment as well as the expectations and demands of diverse stakeholders. So far, CSR committees have been mainly considered as variables of control in larger corporate governance models and independent variables that determine CSR or environmental, social, and governance (ESG) disclosure and its reporting quality. However, the effect on corporate performance has been biased to financial performance, so the potential of the analysis of the effect it may have on different facets of non-financial performance has not been exploited. Which it should, since it can be a fundamental tool to achieve sustainability. The objective of this contribution is to test whether companies with a CSR committee not only leads to higher economic scores, but also to higher ESG (environmental, social, governance) scores. To do this, we used regression panel data models in 197 listed firms in Spain, France, Germany, and the UK during the period 2005–2015 including the perspective of European organizations and…

Sustainability necessitates the protection of infrastructure from any kind of deterioration over the life cycle of the asset. Deterioration in the capacity of reinforced concrete (RC) infrastructure (e.g., bridges, buildings, etc.) may result from localised damage sustained during extreme loading scenarios, such as earthquakes, hurricanes or tsunamis. In addition, factors such as the corrosion of rebars or ageing may also deteriorate or degrade the capacity of an RC column, thereby necessitating immediate strengthening to either extend or ensure its design life is not limited. The aim of this paper is to provide a state-of-the-art review of various strengthening and repair methods for RC columns proposed by different researchers in the last two decades. The scope of this review paper is limited to jacketing techniques for strengthening and/or repairing both normal- and high-strength RC columns. The paper also identifies potential research gaps and outlines the future direction of research into the strengthening and repair of RC columns.

(1) Background: The sharing economy has emerged as a phenomenon widely described by academic literature to promote more sustainable consumption practices such as access over ownership. However, there exists great semantic confusion within academic literature surrounding the term “sharing economy,” which threatens the realisation of its purported sustainability potential. (2) Objective: The aim of this paper is to synthesise the existing academic definitions and propose a definition of the sharing economy from the perspective of sustainability science in order to indicate sharing practices that are consistent with the sustainability claims attributed to the sharing economy. (3) Methods: We conduct a database search to collect relevant academic articles. Then, we leverage qualitative content analysis in order to analyse the authors’ definitions and to synthesise the broad dimensions of the sharing economy in the discourse. (4) Results: We propose the following characteristics, or semantic properties, of the sharing economy for sustainability: ICT-mediated, non-pecuniary motivation for…

Coincident with the rapid growth of omni-channel retailing, growing urbanization, changing consumer behavior, and increasing focus on sustainability, academic interest in the area of last mile logistics has significantly increased. The growth in academic publications has been tremendous, with three out of four articles appearing within the past five years. The influx of research spans multiple disciplines and various methodologies, underlining the complexity and fragmentation of last mile logistics research, which leads to a lack of unity in the understanding of the concept. We provide a systematic review and classification of the literature to provide a more coherent view of last mile logistics research. The review covers 155 peer-reviewed journal publications focusing on last mile logistics. Findings demonstrate that the literature embraces a diversity of aspects and facets that are classified into five themes: emerging trends and technologies, operational optimization, supply chain structures, performance measurement, and policy. Further, we propose a framework of last mile…

Specifically, the paper identifies whether and to what extent scholars have explored these interconnections and maps to get to a conceptual structure of the field under investigation. The results identify the development status and the leading trends in terms of impact, main journals, papers, topics, authors, and countries. The analysis and the graphical presentations are crucial, as they can help both researchers and practitioners to better understand the state of the art of sustainable tourism in the experiential and digital era.

The green facades and living walls of vertical greenery systems (VGS) are gaining increasing importance as sustainable building design elements because they can improve the environmental impact of a building. The field could benefit from a comprehensive mapping out of VGS types, an improved classification and nomenclature system, and from linking the benefits to a specific construction type. Therefore, this research reviews existing VGS construction types and links associated benefits to them, clearly differentiating empirical from descriptive supporting data. The study adopted a scoping research review used for mapping a specific research field. A systematic literature review based on keywords identified 13 VGS construction types—four types of green facades, nine types of living walls, and ten benefits. Thermal performance, as a benefit of VGS, is the most broadly empirically explored benefit. Yet, further qualitative studies, including human perception of thermal comfort are needed. Improvements in air quality, reduction of noise, positive effects on hydrology, and visual benefits…

Greenhouse gases such as sulfur dioxide, nitrogen dioxide, and carbon dioxide have been recognized as the prime cause of global climate change, which has received significant global attention. Among these gases, carbon dioxide is considered as the prominent gas which motivated researchers to explore carbon reduction and mitigation strategies. Research work on this domain expands from carbon emission reporting to identifying and implementing carbon mitigation and reduction strategies. A comprehensive study to map global research on carbon emissions is, however, not available. Therefore, based on a scientometric analysis method, this study reviewed the global literature on carbon emissions. A total of 2945 bibliographic records, from 1981 to 2019, were extracted from the Web of Science core collection database and analyzed using techniques such as co-author and co-citation analysis. Findings revealed an increasing trend of publications in the carbon emission research domain, which has been more visible in the past few years, especially during 2016–2018. The most significant…

Energy generation is heavily dependent on fossil fuels in Pakistan. Due to the huge population and current progress in industrialization, these sources are not fulfilling the existing energy needs of the country. Meanwhile, they have adverse environmental impacts and are economically unsuitable to electrify remote areas. Consequently, there is a need to look for alternate energy sources. The aim of this paper is to find out the best renewable energy option for Pakistan. For this purpose, we have collected data for solar radiation and wind speed for a period of one year in four major cities of Pakistan. Results indicate that solar energy is the best renewable energy option for Pakistan in terms of price, life span, operation and maintenance cost. Key barriers have been identified over the whole solar energy spectrum through semi-structured interviews with industry professionals. And finally, important policy recommendations have been proposed for institutions and government to overcome these barriers and utilize maximum solar energy in the country.

The circular city is emerging as new concept and form of practice in sustainable urban development. This is a response to the complex and pressing challenges of urbanization, as highlighted in the New Urban Agenda (NUA). The concept of a “circular city” or “circular city-region” derives from the circular economy model applied in the spatial territorial dimension. It can be associated with the concept of a “self-sustainable” regenerative city, as stated in paragraph n.71 of the NUA. This paper aims to develop an extensive form of “screening” of circular economy actions in emerging circular cities, focusing on eight European historic port cities self-defined as “circular”. The analysis is carried out as a review of circular economy actions in the selected cities, and specifically aims to identify the key areas of implementation in which the investments in the circular economy are more oriented, as well as to analyze the spatial implications of the reuse of buildings and sites, proposing a set of criteria and indicators for ex-ante and ex-post evaluations and monitoring of circular…

Knowledge can influence the whole decision-making process of consumers. While green product knowledge is often conceptualized as a direct antecedent of green purchase intention, empirical findings in support of this relationship are inconsistent. Based on 236 samples, this study investigates how green product knowledge promotes consumers’ green purchase intention. Results show that green trust and perceived consumer effectiveness partly mediate the relationship between green product knowledge and green purchase intention. The relationship between green trust and green purchase intention is positively moderated by perceived price. Compared with low perceived price, green trust has a greater effect on green purchase intention in the case of high perceived price. However, the relationship between perceived consumer effectiveness and green purchase intention is not moderated by perceived price. This study provides a new insight into green product knowledge and how to promote green purchase intention, and the findings help government and enterprises to formulate strategies to promote…

Nowadays, Lean Manufacturing, Industry 4.0, and Sustainability are important concerns for the companies and in a general way for the society, principally, the influence of the two production philosophies, Lean Manufacturing and Industry 4.0, in the three main pillars of sustainability: economic, environmental, and social. According to the literature review done in this work, these relations are not well known and are dispersed by different sustainability’s criteria. To address this gap, this research proposes a structural equation model, with six hypotheses, to quantitatively measure the effects of Lean Manufacturing and Industry 4.0, in Sustainability. To statistically validate such hypotheses, we collected 252 valid questionnaires from industrial companies of Iberian Peninsula (Portugal and Spain). Results show that: (1) it is not conclusive that Lean Manufacturing is correlated with any of the sustainability pillars; and (2) Industry 4.0 shows a strong correlation with the three sustainability pillars. These results can contribute as an important decision support for the…

The UN Transforming our World: The 2030 Agenda for Sustainable Development (herein, Agenda 30) and the Sustainable Development Goals (SDGs) offer both a set of aspirations for the kind of future we would like to see for the world and a suite of targets and indicators to support goal implementation. Goal 4 promotes quality education and Target 4.7 specifically addresses Education for Sustainability. However, creating a monitoring and evaluation framework for Target 4.7 has been challenging. The aim of this research was to develop a meaningful assessment process. We used a dialogical intervention across complementary expertises and piloted concepts in a trainer workshop. We then developed a modified competency framework, drawing on previous competency models but innovating through the addition of intrapersonal competencies, a self-reflective validation scheme, a focus on non-formal learning, and specific alignment with SDG 4.7 requirements. Through exploration of how such learning could be activated, we proposed the use of multiple intelligences. Education plays a synergistic role in…

Understanding the dynamics of food production is critical to improving food security. This is particularly important in regions that rely on subsistence agriculture with little adaptive capacity to climate change. Sorghum plays an important role in food security in some of the poorest parts of the world. This article reviews the literature to identify and examine the major factors affecting sorghum production in three major production regions. Factors were not categorized ex ante but rather determined from the review. Ten major factors were identified as having notable impacts on sorghum production: climate change, population growth/economic development, non-food demand, agricultural inputs, demand for other crops, agricultural resources scarcity, biodiversity, cultural influence, price and armed conflict. This synthesis revealed that (1) multiple factors simultaneously affect sorghum production; (2) the effect of each factor is greatly influenced by the magnitude and certainty of one or more other factors; and, (3) factors differ in relevance and degree with regard to geography.…

The aim of this paper is to study the role of socially responsible activities on shareholder value creation in a sample of 166 banks from 31 countries over the 2010–2015 period. Prior research about this relationship is scarce and limited to the period before and during the global financial crisis. In contrast, this research analyzes banks over a period of time when these institutions have increased their social responsibility practices in order to reinforce their credibility and the trust their stakeholders have in them. More precisely, we analyze the relationship between these two magnitudes distinguishing between environmental, social, and corporate governance actions as well as between countries taking into account the level of development, legal systems, and the geographic area. Our findings are relevant not only for academics, but also for the managers of these companies, policymakers, investors, and society in general.

Green bonds are a financial tool that has been vigorously promoted in the global green finance field in recent years. Since 2013, the global issuance of green bonds has seen explosive growth. China’s green bond market has made great progress, rising to the top tier of global rankings. In this paper, Chinese listed companies that issue green bonds are used as the research object to explore the impact of green bond issuance on companies, including the impact of the announcement of green bond issuance on companies’ stock prices, as well as the impact of green bond issuance on companies’ financial performance and corporate social responsibility (CSR). The empirical results indicate that announcements of green bonds issuance have a positive impact not only on companies’ stock prices, companies’ profitability, and operational performance, but also on innovation capacity, and can improve companies’ CSR. Overall, the issuance of green bonds has a positive impact on companies, can contribute to environmental improvement, promotes CSR and value creation, and helps to attract investors to some…
