摘要

This study explains factors of historical changes in CO_2 emission reduction of the Japanese manufacturing industryand its sectors at the prefectural level. We decomposed the change of CO_2 emissions in 47 prefectures from 1990 to2013 into four factors (carbon intensity, energy intensity, structure, and activity effects) using the logarithmic meanDivisia index method. We found that that energy intensity, structure, and activity effects were more influential inchanges of emissions than the carbon intensity effect, although the most influential factor varied by prefecture. Amongeight industrial sectors in the manufacturing industry, the chemistry and metal sectors were particularly remarkable inthe changes. Thus, improvements in energy intensity and production in these two sectors should be prioritized. Wealso conducted detailed analysis of the decomposed factors in three selected prefectures based on cluster analysis.
