Initiatives and outcomes of green supply chain management implementation by Chinese manufacturers

This paper aims to explore the green supply chain management (GSCM) initiatives (implementation) of various manufacturing industrial sectors in China and examine the links between GSCM initiatives and performance outcomes. We conducted a survey to collect data from four typical manufacturing industrial sectors in China, namely, power generating, chemical/petroleum, electrical/electronic and automobile, and received 171 valid organizational responses for data analysis. Analysis of variance (ANOVA) was used to analyze the data. The results are consistent with our prediction that the different manufacturing industry types display different levels of GSCM implementation and outcomes. We specifically found that the electrical/electronic industry has relatively higher levels of GSCM implementation and achieves better performance outcomes than the other three manufacturer types. Implications of the results are discussed and suggestions for further research on the implementation of GSCM are offered.     

An institutional theoretic investigation on the links between internationalization of Chinese manufacturers and their environmental supply chain management

Increased market internationalization with more and stricter environmental regulations in different countries has caused manufacturers to extend their environmental management practices to cover their supply chain partners. Thus, environmental supply chain management (ESCM) has become an important competitive and environmental strategy for manufacturers to pursue. China, as a global manufacturer, is also facing this balance of economic development with environmental protection. The literature remains unclear on whether internationalization is beneficial or costly when it comes to environmental management practices such as ESCM within China. Further insight into this issue will be useful for organizations in developing and emergent economies to more effectively prepare for internationalizing their operations and markets. Using internationalization drivers that propel the implementation of environmental management practices in the Chinese manufacturing industry, we applied cluster analysis to group a sample of 377 Chinese manufacturers surveyed in 2007 into three clusters: mature internationalization, emergent internationalization, and domestic-focused. Institutional theory within an internationalization context sets the theoretical foundation for evidence that the international environmentally oriented institutional drivers encountered are positively associated with the adoption of ESCM practices by Chinese manufacturers. We also find significant differences in the environmental, economic and operational performance outcomes across the three manufacturer clusters. We conclude that manufacturing organizations experiencing internationalization with a greater extent of adopting ESCM practices tend to perform better.     

An integrative framework for sustainable supply chain management practices in the oil and gas industry

This paper proposes a framework for understanding the contextual factors of sustainable supply chain management (SSCM) practices in the O&G industry. It is based on a literature review of studies related to SSCM of O&G topics. The review reveals that there is a lack of SSCM research specific to the industry. Present studies focus on individual stages of its supply chain and do not consider all dimensions of sustainable development, namely economic, environmental and social factors. In addition, existing frameworks lack important contextual aspects of the industry's business and organizational environment. To address these gaps, our research develops an overarching framework operationalizing the internal and external contextual factors of the O&G industry environment that can influence the outcome of its SSCM practices. The proposed framework is useful as a tool in the formulation and implementation of SSCM strategy that enables alignment of a company's internal capabilities with its external environment.     

Development of key performance measures for the automobile green supply chain

The main purpose of this study was to develop a set of measures for evaluating the performance of the automobile green supply chain. This study reviewed various literatures on green supply chain performance measurement, environmental management, traditional supply chain performance measurement, and automobile supply chain management. In order to comprehensively and effectively establish the relevant measures, a suitable framework which considered the automobile green supply chain as a two-in-one chain was adopted. This two-in-one chain comprised a forward and backward chain for the automobile industry. Consequently, 10 measures with 49 metrics and 6 measures with 23 metrics were identified and developed for the forward and backward chains, respectively. Sequel to the development of these measures, a survey was conducted using a four-page questionnaire distributed to experts (including academics and practitioners) to establish their importance and applicability. The findings of this study suggested that the importance and applicability of all the developed measures have been substantiated. For the forward chain, the most crucial measure was customer perspective while the most applicable one was traditional supply chain cost. The reverse chain measures were topped by management commitment in terms of both importance and applicability. This study contributed to the advancement of knowledge by pioneering the development of a set of holistic measures for evaluating the performance of the automobile green supply chain. The study was wrapped up with the proposition of directions for further studies.     

The effective practices of mobile phone producers' green supply chain management in reducing GHG emissions

The aim of this study is to identify management practices that effectively reduce greenhouse gas (GHG) emissions with regard to the green supply chain adopted by mobile phone producers. Six cases were surveyed (Apple, Samsung, LG, Huawei, Nokia, and ZTE). The main source of data was sustainability reports, which were retrieved from the Global Reporting Initiative database. A special data analysis technique called rank analysis was adopted. The results revealed that the effective practices to reduce GHG 1 emissions were related to production process and business travel; those that were effective for reducing GHG 2 emissions were related to facilities accreditation and energy saving; and those effective in reducing GHG 3 emissions were related to logistics and customer practices. No effective actions related to the management of relationships with suppliers were identified by this study. Indicative models for the relationship between actions and GHG emissions were developed, as was a value‐stream map. The previous studies reporting the effective practices in other industries reported results for reducing GHG 1 or GHG 3, or overall GHG emissions, without discriminating among the actions taken to reduce such emissions, although some limited actions were reported. This study describes the effective practices along the whole supply chain—both upstream and downstream—and it also lists the actions related to addressing all the emissions, whether GHG 1, 2, or 3.     

Green supply chain initiatives among certified companies in Malaysia and environmental sustainability: Investigating the outcomes

The relationship between green supply chain initiatives and performance outcomes has been subject to numerous studies but the results are not conclusive. This study tries to assess the actual environmental, economic and intangible outcomes resulting from the adoption of green supply chain initiatives. This study used a structured questionnaire derived from the literature and employing a mail survey to collect responses form a group of 569 ISO 14001 certified firms in Malaysia. The results of testing the hypotheses that predicted that green supply chain initiatives have positive effect on the outcomes showed that eco-design have significant positive effect on the four types of outcomes (environmental outcomes, economic outcomes, cost reductions, and intangible outcomes). Reverse logistics was found to have significant positive effect on cost reductions only. However, green purchasing was not found to have significant effect on any of the four types of outcome. Through designing environmentally friendly products and taking back products and packaging, business organizations can generate benefits to the environment, in the form of reduced waste and better resource utilization, in addition to economic benefits and cost reductions to the organizations.     

A taxonomy of green supply chain management capability among electronics-related manufacturing firms in Taiwan

This study investigated crucial green supply chain management (GSCM) capability dimensions and firm performance based on electronics-related manufacturing firms in Taiwan. On the basis of a factor analysis, six green supply chain management dimensions were identified: green manufacturing and packaging, environmental participation, green marketing, green suppliers, green stock, and green eco-design. According to their factor scores in the GSCM dimensions, a cluster analysis subsequently assigned responding firms into four groups, namely, the weak GSCM oriented group, the green marketing oriented group, the green supplier oriented group, and the green stock oriented group. Differences in firm performance and GSCM dimensions among groups were examined. Results indicated that the green marketing oriented group performed best. Based on the resource-based view (RBV), the capability of the green marketing oriented group was considered to be the deployment of a collection of resources that enables it to successfully compete against rivals. The importance of green marketing as a GSCM capability and strategic asset/critical resources for electronics-related manufacturing firms to obtain a competitive edge is therefore highlighted in this study.     

Designing a mixed performance measurement system for environmental supply chain management using evolutionary game theory and balanced scorecard: A case study of an auto industry supply chain

This paper proposes a mixed performance measurement system using a combination of evolutionary game theory and the balanced scorecard (BSC) in environmental supply chain management (ESCM) that measures and evaluates business operations using the four different perspectives of finance, customer, internal business process, and learning and growth. ESCM plays an important role in the supply chain which leads to the reduction, reuse and recycling of resources involved in both upstream and downstream activities. This paper presents guidance for practical managers in evaluating and measuring ESCM by developing a knowledge-based BSC and evolutionary game theory. The primary purpose of this paper is to apply the proposed method in a case study to one of Iran's biggest auto industry supply chain SAIPA Company. The results of this study indicate that the adoption of ESCM, in the absence of regulatory pressures and cost-saving measures is triggered by public pressures and its implementation is limited by organizational factors and strategic myopia.     

A fuzzy multi criteria approach for evaluating green supplier's performance in green supply chain with linguistic preferences

Today's international business environment has forced many firms to focus on supply chain management to gain a competitive advantage. During recent years, supplier selection process in the supply chain has become a key strategic consideration. With the growing worldwide awareness of environmental protection and the corresponding increase in legislation and regulations, green purchasing has become an important issue for companies to gain environmental sustainability. Traditionally, companies consider criteria such as price, quality and lead time, when evaluating supplier performance and do not give enough attention to environmental criteria as a means to evaluate suppliers. Now, many companies have begun to implement green supply chain management (GSCM) and to consider environmental issues and the measurement of their suppliers’ environmental performance. This paper examines GSCM to propose a fuzzy multi criteria approach for green suppliers’ evaluation. We apply fuzzy set theory to translate the subjective human perceptions into a solid crisp value. These linguistic preferences are combined through fuzzy TOPSIS to generate an overall performance score for each supplier. A numerical example is presented to demonstrate the effectiveness of the proposed approach.     

Green shipping practices in the shipping industry: Conceptualization, adoption, and implications

There have been increasing concerns about the adverse impacts on the environment caused by cargo movement in international trade. Different stakeholders ranging from shippers and carriers to government bodies and international communities have expressed worries about the environmental impacts brought by shipping related activities. The pollution and waste created in the shipping processes have imposed environmental burdens and accelerated resource depletion. The situation is set to worsen in the face of intensifying trade globalization, which has contributed to sustained growth in international shipping activities. To help protect the environment, many shipping firms have taken the initiative to find ways to lessen the environmental damage of their operations while enhancing their performance. The objective of this study is to examine the environmental awareness and the environmental measures taken in the shipping industry. We propose a conceptual framework for evaluating green shipping practices and develop several propositions stating the conditions under which shipping firms would behave in an environmentally responsible manner. We conclude with managerial and policy implications of the conceptual framework to promote green shipping practices in the shipping industry.     

Socially optimal and fund-balanced advanced recycling fees and subsidies in a competitive forward and reverse supply chain

Advanced recycling fees (ARFs) and government subsidy fees are important for curtailing the consumption of new products and encouraging recycling and disposal of end-of-life (EOL) products. We introduce a model consisting of a leader (the Environmental Protection Agency, EPA) and two groups of followers (MIS firms and recyclers) consisting of manufacturers, importers and sellers, and recyclers which compete in both consuming and recycling markets. The EPA determines the ARFs paid by the MIS firms and the fees subsidizing recyclers to maximize the social welfare in closed-loop supply chains where the MIS firms and recyclers attempt to maximize their respective profit functions. To compare with current practice, we describe a conceptual fund balance model to determine the ARF and subsidy fee on the basis of the balance between total collected ARFs and expenditure of subsidies. Using numerical examples for the laptop computer market in Taiwan, we demonstrate that our results outperform the current practice.     

Greenhouse gas emissions and energy balance of sunflower biodiesel: Identification of its key factors in the supply chain

The production of first generation biofuels, such as sunflower-based biodiesel, is potentially an option for diversifying the energy matrix in several South American countries. However, biofuels present environmental challenges, especially concerning the reduction of greenhouse gas (GHG) emissions. This study, using a life-cycle approach, evaluates the GHG emissions and energy balance of the future nationwide production of sunflower-based biodiesel in Chile. Direct land use change is included in the analysis. The overall findings indicate that sunflower biodiesel, under the most likely production conditions, will have better environmental performance than fossil diesel in terms of both indicators. The agricultural stage is associated to key factors such as land use change, and nitrogen fertilizers. These factors contribute significantly to GHG emissions or energy demand in the biodiesel life cycle. The sensitivity analysis shows that no GHG emission saving could occur if nitrogen fertilizers rate exceeds 330 kg N/ha. In order to reduce the environmental impacts of this biofuel, improvement measures are suggested.     

Mixed methodology to analyze the relationship between maturity of environmental management and the adoption of green supply chain management in Brazil

The aim of this research is to verify the relationship between the maturity levels of environmental management and the adoption of green supply chain management (GSCM) practices by electro-electronic companies in Brazil. In this work a two-phase research was conducted, with one quantitative and the other qualitative. The quantitative phase aimed to test whether a relationship between the maturity levels of environmental management and GSCM exists, while the qualitative phase tried to detail the characteristics of this relationship. The quantitative phase was conducted through a survey with 100 Brazilian electro-electronic companies and the collected data were processed using Structural Equation Modeling. For the qualitative phase, a multiple case study was conducted with three companies located in Brazil. The results indicate that: (1) The main hypothesis was confirmed and considered statistically valid, indicating that, indeed, the maturity level of environmental management influences the adoption of GSCM practices; (2) a coevolution tends to occur between the environmental maturity and the GSCM practices; that is, the more developed is the company's environmental management, more complex GSCM practices are adopted; and (3) the GSCM internal practices tend to present a greater relative adoption than the external practices; these external practices of GSCM tend to be adopted when the company is inserted in a higher environmental stage and/or operates under a scenario of stronger normative environmental pressure. By the way, this is the first research mixing survey and case studies on GSCM in Brazil.     

Experimental investigation on the performance and emission characteristics of a diesel engine by varying the injection pressure and injection timing using mixed biodiesel

Biodiesel is a promising fuel for compression ignition engines instead of diesel fuel. Due to the depletion of diesel fuel, an alternative fuel can be used in an engine. The experiments were conducted on a four-stroke, single cylinder CI engine. In this present investigation, an attempt has been made to study the influence of injection pressure (IP) and injection timing (IT) on the performance and emission characteristics of diesel engines by using mixed biodiesel (Thevetia peruviana, Jatropha, Pongamia, and Azadirachta indica). The injection pressure is varied from 200 to 230 bar and the injection timing is varied from 23 to 29° bTDC at an increment of 10 bar and 2° bTDC, respectively, and the results were compared with diesel. From this study, the results showed that the brake thermal efficiency (BTE) was increased by 2.4% with an increase in injection pressure and 1.5% with an increase in the injection timing for the maximum load, but lesser than diesel. Furthermore, a reduction of 5.08% of brake specific fuel consumption (BSFC) has been noticed for the rise in IP and IT with loads but higher than diesel. The reduction was 34.17%, 53.85%, and 29.7% and 29.17%, 53.85%, and 21.95% of hydrocarbons (HC), carbon monoxide (CO), and smoke emissions, respectively, at 230 bar injection pressure and at 27° bTDC injection timing. Also, a significant increase in nitrogen oxides (NO_x) and carbon dioxide (CO₂) emissions at the maximum load was observed by increasing the injection pressure and injection timing.     

Status,stigma and energy practices in the home

Domestic energy practices are a topical policy issue, with implications for climate change, energy security and fuel poverty. Accordingly, a growing body of literature examines ways of promoting energy conservation and generation by individuals. However, there has been relatively little discussion of how status and stigma are implicated in these practices, and may act as facilitators or barriers to “behaviour change”. To help address this gap, this article draws both on existing literature and a new UK-based study of people who are attempting to live sustainable lives, to provide insights into how domestic energy practices may be status-enhancing or stigmatising, and how these risks and opportunities can be managed. While energy practices are often understood as “inconspicuous”, it is argued here that in some circumstances individuals may actively manage the visibility of their energy practices. The discussion considers these findings with regard to social power relations, and identifies issues warranting further exploration within the emerging research agenda on energy and equity.

Green jobs,livelihoods and the post-carbon economy in African cities

This article examines the potential contribution of household scale off-grid renewable energy generation to the post-carbon economy. The large-scale focus of the green jobs agenda in high-income countries obscures how small-scale technologies can be a transformative source of employment in developing economies. Debates about what constitutes a green job and their value leaves out the everyday practice of green livelihoods carried out by the urban poor across the African continent in unfavourable institutional contexts where nonrenewable fuel is subsidised and renewable energy inputs are heavily taxed. The article presents experiences from field work in several countries, including Egypt, Nigeria and Kenya to provide practical examples of communities pursuing strategies of income generation, community empowerment and environmental preservation. We argue that scholars and practitioners concerned with both social justice and environmental preservation should embrace a definition of green jobs that is bottom-up or people-centred. The grassroots experiences highlighted illustrate the important role of non-governmental organisations in supporting transformative, locally sustainable green employment and livelihoods by piloting demonstration projects, fostering innovation, conducting research, forming coalitions and engaging in advocacy when local institutions and market conditions make both consumers and providers risk averse to off-grid renewable energy adoption.     

Agricultural practices,ecology, and ethics in the third world

The increasing demand for horticultural products for nutritional and economic purposes by lesser developed countries (LDC's) is well-documented. Technological demands of the LDC's producing horticultural products is also increasing. Pesticide use is an integral component of most agricultural production, yet chemicals are often supplied without supplemental information vital for their safe and efficient implementation. Illiteracy rates in developing countries are high, making pesticide education even more challenging. For women, who perform a significant share of agricultural tasks, illiteracy rates are even higher than for men. The dilemma exists of how a developing country can improve its nutritional and economic situation without giving consideration to social and environmental consequences.     

Community engagement in the Transition movement: views and practices in Portuguese initiatives

As the need to address climate change is ever more urgent, many have emphasised the importance of community-level responses. The Transition movement has advanced community-based action to increase resilience for over a decade and has expanded significantly. Thus, it is a critical setting for examining community engagement towards climate change in practice. Our study is based on 39 interviews with facilitators of Transition initiatives in Portugal, coupled with observational data, and is guided by two main research questions: how do Transition initiatives promote community engagement at the local level? What are the factors constraining or facilitating community engagement within Portuguese Transition initiatives? We identify several aspects of Transition’s constructions of community resilience and engagement that indicate ambivalence towards, or avoidance of, certain issues. They relate do agency, structure, power and inclusion, as well as to the modes of engagement and the communication practices of Transition initiatives. We argue that strategies for community engagement should be specific to social contexts rather than internationally uniform and be based on participatory approaches. Drawing on an extensive empirical analysis, the article contributes to theory building on the Transition movement beyond the Anglo-Saxon context and to the wider field of community-based environment initiatives.
