It is believed that the global warming, which may cause abnormal weather patterns and global environmental disruption, has been affected by green house effect gas emission from human activities. The global warming has been studied in various fields of science. It has been carried out that the monitoring systems and the simulation models for climate change in natural science. In social science, quantitative analysis of human activity influence and estimation of feasibility of environmental policies have been conducted. Especially, in environmental economics, some researches have analyzed environmental tax policies with the aim of constructing socio-economic systems which do not cause environmental disruption. Though these researches analyzed Japan's socio-economic system similarly, they used different data and supposed different conditions of economy and policies. Therefore we can not compare and examine possible tax policies. In this study, we survey these previous researches to grasp each characteristic of policy, and run simulations under same condition of economy using latest data. From results of simulations, we can discuss the feasibility of environmental tax policies.
