Globalization has resulted in pressure on multinational firms, especially in technology- intensive industries, to improve environmental performance. This study presents a hierarchical structure of green supplier assessment that addresses actual environmental performance using Fuzzy Analytical Hierarchy Process (AHP). Regarding the data collected, a random sample of 28 functional area managers was drawn from communication equipment manufacturing organizations located in South Africa. The major contribution of this research lies in its suggestions for how decision makers may improve environmental performance using green supply chains.
