The purpose of this study is to explore the trend of CO2 emission in the electricity industry. An input-output analysis and FGP along with the IPCC method are employed to estimate the volume of CO2 emission produced from power sources in the electricity industry from 1996 to 2006, focusing on the correlation between derived energy and carbon dioxide. The potential volume of CO2 emission in Taiwan between the years 2007 and 2015 is also estimated according to the information on the government's long-term development program. Furthermore, the input-output approach and FGP model is constructed to draft future CO2 reduction program for the electric power industry. The program includes fuel substitute of dynamotors and the promotion of electrical efficiency; at the same time, analysis is made on the correlation between CO2 and GDP in this reduction program.

摘要 研究目的为探讨电力事业中二氧化碳排放趋势，以投入产出分析法及模糊目标规划法搭配IPCC方法，推估1996~2006年间整体产业各能源二氧化碳排放量，重点为次级能源电力与二氧化碳间的关联性，并依据我国长期开发方案所提供资料推估我国2007~2015年间二氧化碳排放量，并进一步建构投入产出模糊规划模型，拟定未来电力事业可行的二氧化碳减量方案，方案包括发电机组燃料替代与电力效率提高两种，并且分析减量方案中产业二氧化碳与GDP两者间的关系。
