| Summary: | 碩士 === 國立臺灣大學 === 農業經濟學研究所 === 98 === Carbon mitigating action normally will damage economy. A country, however, may pay more in the future if she hesitates to take mitigating action now. The purpose of this study designs a specific “carbon mitigating framework” in which various scenarios of mitigation models will be provided for each individual country while confronting different targets of mitigation and choices of mitigation period.
The “carbon mitigating framework” is based on the targets which are “Kyoto mitigatiion targets” and other targets that are following Kyoto Protocol according to potential international mitigating agreements. The “once mitigation” to achieve the mitigation target and the “annual mitigation” to achieve the mitigation target are two kinds of mitigating period choices used in the study. “Do it now or delay later” phenomenon reflects on the actions designed for “the early mitigating” and “the delay mitigating.” Estimation, computation, and comparison are made by the cost difference in terms of gross domestic product for different aspects of target, mitigation period, and actions.
The empirical results demonstrate that the scenarios with “the delay mitigating action” cost much higher than that “the early mitigating action” by 1.00 to 5.17 times based on the same target and choice of mitigation period. Similarly, “the delay mitigating actions” with “once mitigation” also cost more than that “the early mitigating actions” with “annual mitigation” by 2.39 to 5.42 times based on the same mitigation target. These importment conclusions support a specific cost saving of “no regret policy.” These conclusions is universally true for all the 31 countries, with various levels of economic development, at hand.
