Abstract
Building sector is the highest growing sector in energy demand in Japan at present. There is a strong need to reduce this sectoral energy demand to achieve the national carbon emission target.
This study focuses on Japanese commercial sector and shows model analysis results of energy efficiency policy impacts on the sectoral carbon emission trajectory, using CRIEPI’s bottom-up energy model. The policy cases we analyzed are consistent with those of other EMF25 model teams. The results indicate that, the introduction of low carbon tax has little impact on the sectoral final energy demand and carbon emission trajectory and, on the other hand, enhanced energy efficiency standard and reduced equipment cost of products are very effective on reducing the sectoral energy demand.
