초록

As the EU and developed countries have taken advantage of trade barriers using the regulation of greenhouse gas (GHG), the economic burden due to GHG emissions has been increased. It is necessary to establish a new strategy to reduce GHG emissions which had been recognised just as environmental issues before. Considering the cost for new technologies to meet reduction goals of GHG emission in the long-term perspective and for investigation of the characteristics of GHG to minimize the reduction cost, it have many difficulties to achieve GHG reduction targets. In order to establish various policies to set appropriate reduction goals for GHG emission in the future, first things to do is to estimate the GHG reduction potential according to the current GHG emission. In this paper, international studies on approach methodologies to evaluate the GHG reduction potentials, estimation techniques, and their case studies were analysed. Key considerations to calculate GHG reduction potential, calculated results and the reduction effects of modal-shift were also investigated.
