배출권거래제도에서의 CO₂ 배출량 산정 방법의 경제성비교 분석

초록

TMS(Tele-metering System) and the carbon emission factor method are the alternative measurement methods for greenhouse gas emissions. TMS incurs fixed cost such as the fa- cilities(gas analyzer, data log) expense at the very beginning. For that reason, TMS is usually considered as an expensive method. However, carbon emission factor method involves costs for consulting fee and the third party verification cost as well. In this paper, the costs of the two methods are analyzed and compared, given that the TMS is already installed to the emission sources for the purposes other than CO₂ measurements such as air pollutants controls. The result of the analysis, based on the data gathered from the consulting firms and TMS equipment manufacturers, shows that the carbon emission factor method is found to involve higher cost than the TMS method if the plant has less than five stacks. Especially, in the case of less than three stacks, the expense of the TMS is as half as compared to that of the carbon emission factor method. It means that the TMS method is cheaper than carbon emission factor method in small scale businesses. If the benefits of TMS is taken into consideration, it can be said that TMS has enough competitiveness vis a vis the carbon emission factor method.
