This study focused on steel as an example of energy-intensive materials, and developed a model to estimate 1) service demands supplied from goods stocks, 2) the amount of steel stock included in the goods stocks, and 3) steel demands. This model was applied to time period for 2005-2050 with the assumption of four future scenarios including FIX scenario, in which parameters were fixed at a level of 2005.
Reduction effects of steel stocks and steel demands were analyzed by the model. As the results, the steel demands of MIX scenario, which introduced high performance materials and the efficiency improvement of goods stocks, was the lowest among the scenarios and it showed 40% reduction compared with FIX scenario. The possibility for shifting towards dematerialized society was indicated, with keeping the service demands at the level of 2005.
