| Summary: | 碩士 === 國立成功大學 === 資源工程學系 === 102 === Climate change is one of major global issues. As an export-oriented country, even though Taiwan is not a member of the UNFCCC, for maintaining the national competence, the Taiwan government still popularizes CO2 emission reduction activities and consults to imitate international CO2 emission reduction mechanism for achieving reduction target of Taiwan. Taiwan government promotes National Action Plan on Energy Conservation and GHGs Emission Reduction for reducing national CO2 emissions to 2005 levels by 2020 and to 2000 levels by 2025.
According to reduction policies of Environmental Protection Administration, domestic emission trading mechanism is one of the possible instruments for achieving the aim of CO2 reduction. Considering the industrial sector is the largest emitter of CO2 emissions. This study analyses the influence of emission trading mechanism of industrial sector on CO2 emissions and electricity consumption.
Free CO2 emission allowances, CO2 price and expected trading cost of CO2 of emission trading mechanism are closely connected with electricity consumption and CO2 emissions. The behavior includes feedback and time delay which are the feature of system dynamics approach, so this study applies system dynamics approach to discuss emission trading mechanism. In addition, there are three main factors of emission trading mechanism which are free CO2 emission allowances, initial CO2 price and CO2 reduction cost. This study aims to research the critical factors affecting the effectiveness of emission trading mechanism and offer some policy suggestions.
The main simulation results of this study are:
1. Free CO2 emission allowances, initial CO2 price and CO2 reduction cost are three main factors of emission trading mechanism. After the implementation of emission trading mechanism of industrial sector, the trend of volume of tradable CO2 emission allowances, CO2 emissions and electricity consumption shows that the most critical factors affecting CO2 emissions is volume of tradable CO2 emission allowances. Besides, the volume of tradable CO2 emission allowances is affected by the volume of free CO2 emission allowances. The result shows that reduction of electricity consumption cannot affect CO2 emissions conspicuously.
2. The result also shows that free CO2 emission allowances is the critical factor affecting the effectiveness of emission trading mechanism. Because of free CO2 emission allowances will affect intention of attending emission trading mechanism by industry and the reduction effectiveness. Initial CO2 price is the secondary factor affecting the effectiveness of emission trading mechanism. The reason is that CO2 price will affect expected trading cost of CO2 to increase or decrease the intention of CO2 reduction. At the same time, the effect of CO2 reduction cost is smaller than other factors.
