Under this situation, all the Taiwanese companies need to adjust their environmental policy and practices, and well as prepare the pressure may have from the international society. Various strategies regarding electronics industry for mitigating carbon dioxide emission have been proposed in order to maintain competitive advantage. In this study, the author tries to understand how the semiconductor industry responses to the global warming and to find out the common strategies semiconductor companies currently adopt. Based on an extensive literature study, five mitigation and adaptation strategies for companies in response to global warming were identified. They are: Energy Improvement, Process Improvement, Waste Management, Transportation Management and Kyoto Mechanism. Based on this structure, an expert questionnaire of Fuzzy Analytic Hierarchy Process (FAHP) was designed and mailed to the managers who are in charge of this issue of 120 companies who are members of Taiwan Semiconductor Industry Association (TSIA). FAHP technique then was applied to analyze the relative weightings of different strategies and determine the most prioritized strategies of mitigating carbon dioxide for Taiwanese semiconductor industry. 　 　　To explore the differences of strategies for mitigating carbon dioxide, the results were analyzed based on two groups of samples, companies who signed and did not sign the Voluntary Carbon Reduction (VCS) program. Results of those companies who signed VCS (8 respondents) indicate that "transportation" (0.2602) was the most important dimension followed by "waste management" (0.2129), "energy strategy" (0.2045) "product" (0.1766), and "process management" (0.1459). However, results of those who did not sign samples (16 respondents) show that "prodcut" (0.2797) was the most important dimension, followed by "waste management" (0.2081), "transportation" (0.2045) "energy strategy" (0.1766), and "process management" (0.1459). This discrepancy maybe due to that the signed companies have the deadline for reaching the reduction goal; so they tend to adopt the strategies which the results can be demonstrated apparently, such as strategies in the "transportation" dimension. On the other hand, the unsigned companies seem to focus on the whether the strategies can be implemented easily or not. It is expected that the results derived from this study can help decision-makers in the semiconductor industry to identify those strategies where acceptance and improvements can be made and in prioritizing to reduce their global warming gases.
