Factor decomposition analysis of 1985-90-95 linked environmental household accounts using input-output table

Recently UNEP (United Nations Environment Programme) has advocated an action plan focused on new systems of production and consumption as a final step towards sustainable society, after its decades of-work on cleaner production. To achieve the goal, however, so-called "rebound effects" require serious attention, for such effects might offset the environmental benefits of eco-efficient products. In this study, we try to quantitatively clarify the effect based on the method we have developed, i.e. environmental household accounts using input-output table. We first extend the analysis using 1985-90-95 input output table in "linked" form, and then decompose the change in the induced CO₂ emission in the decade into three parts; the effect of the change in consumption structure, the effect of the income increase, and the effect of the technological change. Through the analysis, we identify the changes that are attributable to the rebound effect, and their causes are clarified. The present method, together with the results, provides a base for the design plan for the construction of sustainable consumption society.
