• This paper analyzes the CGE (computable general equilibrium) model based on Japans national accounts and Japans SEEA (system for integrated environmental and economic accounting). First, an environmental SAM (social accounting matrices) was compiled by introducing Japans SEEA into the SAM of Japans national accounts. Then, a CGE analysis of Japans environmental SAM was conducted with a focus on “imputed environmental costs, ” also known as “eco-margin, ” with the use of GAMSHERCULES software.In conclusion, we have gained three main results: 1) an increase in environmental tax rates reduces the eco-margin; 2) an increase in capital has undesirable effects (on the other hand, labor has desirable effects) on the environment; 3) a direct reduction of “imputed environmental costs, ” by increasing inputs needed for environmental protection purposes, has almost no noticeable effects on the rest of the economy, with eco-margin being reduced to zero.
