Selecting green suppliers based on GSCM practices: Using fuzzy TOPSIS applied to a Brazilian electronics company

Due to an increased awareness and significant environmental pressures from various stakeholders, companies have begun to realize the significance of incorporating green practices into their daily activities. This paper proposes a framework using Fuzzy TOPSIS to select green suppliers for a Brazilian electronics company; our framework is built on the criteria of green supply chain management (GSCM) practices. An empirical analysis is made, and the data are collected from a set of 12 available suppliers. We use a fuzzy TOPSIS approach to rank the suppliers, and the results of the proposed framework are compared with the ranks obtained by both the geometric mean and the graded mean methods of fuzzy TOPSIS methodology. Then a Spearman rank correlation coefficient is used to find the statistical difference between the ranks obtained by the three methods. Finally, a sensitivity analysis has been performed to examine the influence of the preferences given by the decision makers for the chosen GSCM practices on the selection of green suppliers. Results indicate that the four dominant criteria are Commitment of senior management to GSCM; Product designs that reduce, reuse, recycle, or reclaim materials, components, or energy; Compliance with legal environmental requirements and auditing programs; and Product designs that avoid or reduce toxic or hazardous material use. © 2013 Elsevier B.V.

GREEN SUPPLY CHAIN: PROTAGONISTA OU COADJUVANTE NO BRASIL?

Questões ambientais passaram a ser introduzidas com maior frequência nos negócios empresariais. Quanto à cadeia de suprimentos, Green Supply Chain Management (GSCM) surge como novo enfoque à responsabilidade das empresas com o meio ambiente. Este artigo objetiva analisar a difusão do conceito e das práticas de GSCM no cenário brasileiro. Para tanto, foram realizadas entrevistas com especialistas do tema cadeia de suprimentos na área de Administração no Brasil. Os resultados indicam que as razões para o lento desenvolvimento do conceito podem relacionar-se com características do mercado nacional, foco empresarial em aspectos internos, falta de legislação rígida e baixa pressão dos consumidores. Especialistas percebem, entretanto, boas perspectivas para o futuro das discussões da temática no País, em virtude da Política Nacional dos Resíduos Sólidos, de pressões do mercado internacional e da busca por certificação ambiental. Este estudo procurou fomentar novas discussões sobre GSCM no Brasil.

Evidências da relação entre a evolução da gestão ambiental e a adoção de práticas de green supply chain management no setor eletroeletrônico brasileiro

Na pesquisa apresentada, teve-se como objetivo verificar se a evolução da gestão ambiental se relaciona positivamente com a adoção de práticas de green supply chain management (GSCM) por empresas do setor eletroeletrônico do Brasil. Para fazer frente ao objetivo exposto, foi realizada uma pesquisa quantitativa, por meio de um levantamento survey, com cem empresas do setor eletroeletrônico brasileiro. Os dados coletados foram processados por meio de técnicas estatísticas descritivas, análise fatorial exploratória e modelagem de equações estruturais. Os resultados mais importantes da pesquisa foram: na amostra, práticas de GSCM orientadas para a recuperação dos investimentos das empresas, como a revenda de materiais inservíveis e outros resíduos, além da adequação à legislação e à auditoria ambiental, obtiveram médias elevadas; e a hipótese de pesquisa (H1) foi confirmada e considerada estatisticamente válida, indicando que a evolução da gestão ambiental influencia a adoção de práticas de GSCM.

Developing green supply chain management taxonomy-based decision support system

The aim of this paper is to develop a comprehensive taxonomy of green supply chain management (GSCM) practices and develop a structural equation modelling-driven decision support system following GSCM taxonomy for managers to provide better understanding of the complex relationship between the external and internal factors and GSCM operational practices. Typology and/or taxonomy play a key role in the development of social science theories. The current taxonomies focus on a single or limited component of the supply chain. Furthermore, they have not been tested using different sample compositions and contexts, yet replication is a prerequisite for developing robust concepts and theories. In this paper, we empirically replicate one such taxonomy extending the original study by (a) developing broad (containing the key components of supply chain) taxonomy; (b) broadening the sample by including a wider range of sectors and organisational size; and (c) broadening the geographic scope of the previous studies. Moreover, we include both objective measures and subjective attitudinal measurements. We use a robust two-stage cluster analysis to develop our GSCM taxonomy. The main finding validates the taxonomy previously proposed and identifies size, attitude and level of environmental risk and impact as key mediators between internal drivers, external drivers and GSCM operational practices.

Gestão verde de tecnologia da informação e comunicação: fatores que influenciam a sua adoção em grandes empresas usuárias no Brasil

A crescente utilização de recursos de informática e comunicação nas empresas, visando modernização, agilidade, redução de custos e outros, tem trazido diversos benefícios, mas tem também se tornado um enorme problema para o planeta. A quantidade de lixo eletrônico (e-waste) gerada pelos equipamentos de informática e comunicação tem dobrado a cada cinco anos, se tornando um dos principais focos de atenção nos últimos anos. O volume de lixo eletrônico gerado pelo descarte de equipamentos de informática e comunicação (TIC), já ultrapassa a marca de 50 milhões de toneladas por ano, o que equivale a oito vezes a produção total de resíduos da cidade de São Paulo. O mercado brasileiro total de eletrônicos é considerado o quinto do mundo, depois da China, Estados Unidos, Japão e Rússia. A produção total de lixo eletrônico no Brasil em 2011 foi de um milhão de toneladas e a parte referente a equipamentos de TIC foi estimada em 98 mil toneladas. Frente a este contexto este estudo visa contribuir para a expansão do conhecimento na gestão verde da cadeia de suprimentos (GSCM) aplicado à realidade empresarial brasileira de TIC. Especificamente pretende-se identificar quais fatores influenciam o processo de adoção e aplicação da gestão verde de TIC, em grandes empresas usuárias de TIC no Brasil, a partir dos modelos propostos por Molla (2008) e Molla e Coopers (2008). Desta forma buscou-se responder ao seguinte problema de pesquisa: quais fatores influenciam grandes empresas usuárias de tecnologia da informação e comunicação (TIC) no Brasil na adoção de conceitos de gestão de verde? Para isto, foi realizado estudo de caso em seis grandes empresas, todas lideres em seus setores, representando grandes áreas de serviços e manufatura. Como resultado final, foi proposto um novo modelo analítico, que pareceu mais adequado ao setor de serviços. O estudo também identificou que na gestão verde de TIC empresas manufatureiras tem prioridades diferentes das de serviço. Muitas vezes seus desafios operacionais são mais críticos em relação à sustentabilidade, que a gestão verde de TIC em si. Por outro lado, o estudo dos serviços prestados pelo setor público apesar dos grandes orçamentos anuais, apontou restrições quanto aos aspectos legais e deficiência de qualificação e capacitação de seus colaboradores como fatores limitantes para a implantação de programas de gestão verde mais abrangentes.

Factors affecting the adoption of green supply chain management practices in Brazil: Empirical evidence

The aim of this study is to identify and analyse the factors that affect the adoption of Green Supply Chain Management practices based on empirical evidence from the Brazilian electronics sector. Data are collected in a survey of 100 electronics companies and analysed using statistical analysis of variance and regression methods. The study finds that the size of the company, previous experience with Environmental Management Systems, and the use of hazardous inputs are positively correlated with GSCM practices adoption. Surprisingly, formal pressure from the stronger tier/player in the supply chain is not correlated with the adoption of GSCM practices. Finally, we present some explanations for these findings and suggestions for future research. © 2013 Copyright Taylor and Francis Group, LLC.

Green supply chain management in local and multinational high-tech companies located in Brazil

The objective of this article is to analyse how green supply chain management (GSCM) practices are being adopted by some high-tech companies located in Brazil. The research was conducted using the case study approach, focusing on eight companies that are representative of this sector. The main results are: (a) the most adopted GSCM practices in the studied high-tech companies located in Brazil are internal environmental management, investment recovery and reverse logistics and (b) Brazilian environmental legislation and international policies are very important in driving the adoption of GSCM practices. The internationalisation of companies was also found to be a variable that interferes with the adoption of GSCM practices. This is one of the first studies that examine the relationship between GSCM and the internationalisation of companies located in Brazil. © 2013 Springer-Verlag London.

Green supply chain management: Mapping the territory

The objective of this paper is to identify the main definitions, related practices and to point out future directions in green supply chain management (GSCM). After a literature review and systematisation of the published articles in this field, it was possible to identify: a) the main research objectives of analysed papers; b) the research methods adopted; c) the predominantly analysed industrial sectors; d) the GSCM practices considered by the researchers. Results are presented in each of these analytical perspectives. The main findings are: 1) there are various classifications, nomenclatures and types of GSCM practices, but the most commonly used by studies in GSCM are cleaner production, product design, reverse logistic and green purchasing; 2) from the highlighted definitions, the tonic is to adapt operating activities and incorporate the supply chain management philosophy (integration/ collaboration) to environmental concerns (impact reduction) in relations between links in the chain. These results can be useful for those interested in environmental management as well as supply chain management, considering the growing interest in GSCM. We also propose a research agenda on this subject. This is one of the most recent literature review and systematisation on green supply chain management. © 2013 Inderscience Enterprises Ltd.

Analysing green supply chain management practices in Brazil's electrical/electronics industry using interpretive structural modelling

Industries need to adopt the environmental management concepts in the traditional supply chain management. The green supply chain management (GSCM) is an established concept to ensure environment-friendly activities in industry. This paper identifies the relationship of driving and dependence that exists between GSCM practices with regard to their adoption within Brazilian electrical/electronic industry with the help of interpretive structural modelling (ISM). From the results, we infer that cooperation with customers for eco-design practice is driving other practices, and this practice acts as a vital role among other practices. Commitment to GSCM from senior managers and cooperation with customers for cleaner production occupy the highest level. © 2013 Copyright Taylor and Francis Group, LLC.

Quality management, environmental management maturity, green supply chain practices and green performance of Brazilian companies with ISO 14001 certification: Direct and indirect effects

This study aims to test a new conceptual model based on the relationship between quality management (QM), environmental management maturity (EMM), adoption of external practices of green supply chain management (GSCM) (green purchasing and collaboration with customers) and green performance (GP) with data from 95 Brazilian firms with ISO 14001. To our knowledge, such links and relationships are not simultaneously identified and tested in the literature. The results indicate the validation of all of the research hypotheses. This paper highlights that an improvement in green performance will require attention to quality management, environmental management maturity, and green supply chain. (C) 2014 Elsevier Ltd.
