The EU officially promulgated on February 13, 2003 that the three Major Environmental Protection Doctrines, i.e., Waste Electronics and Electrical Equipment (WEEE), Restriction of the Use of Certain Hazardous Substance in Electrical and Electronic Equipment (RoHS) and Energy-using Products (EuP). Meanwhile, it banned use of toxic substances in information and electronic products and demanded recycling wastes. Those world-class information giants have followed suit in environmental protection and put into effect thoroughly into information products, totally foiling the previous specifications on the grounds of safety specifications and reliability and prompting huge green products based reforms in a row. The present study conducts in-depth interview and focus groups alongside reorganization of literature and environmental protection oriented issues. It, meanwhile, probes into three case companies covering six major information parts and components industries, i.e., active components, passive components, computer housing, PCB, power supply and connectors. With forty men/times in in-depth interview and five 50-people focus body research, it satisfactorily implementing the green supply chain management model for the information technology industry. Further with case and empirical explanation to orient the applicability of the model, it effectively brings down and solves enterprises in risk and pressure in the supply chains. It provides other industries with conducive and handy reference in breaking through, pulling through the non-tariff trading barrier and subsequent promotion of the environmental protection related issues.
