Abstract
In 2009, the Japanese government published their greenhouse gas (GHG) emission reduction target to reduce GHGs by 25% by 2020 and 80% by 2050. To meet this target, formulating suitable policy has become an urgent issue. In this study, we have developed a model for predicting the low-carbon technology adoption rate based on the detached homeowners’ decision-making structures. In addition, we have considered policies for meeting the reduction target. This study aims to propose policies to meet the reduction target, and to contribute to the realization of a low-carbon society.
