I. Introduction
GSCM has emerged as an important new archetype for enterprises to achieve profit and market share objectives by reducing environmental risk and impact [1]. With the increased environmental concerns during the past decade, awareness is growing that issues of environmental pollution accompanying industrial development should be addressed together with supply chain management, thus contributing to the initiative of GSCM [2]. GSCM thus has emerged as a strategy for some leading companies in the electronics industry [3], including Dell, HP, IBM, Motorola, Sony, Panasonic, NEC, Fujitsu, and Toshiba. This phenomenon implies that companies are now starting to recognize that environmental awareness can be a source of competitive advantage [4]. Meanwhile, the most far-reaching approach of environmental management is to create value through greening the supply chain [1].
