Abstract: Japan has announced that it will achieve carbon neutrality in 2050. Based on the data of Japan’s carbon emissions in CEADs database, this paper decomposes regional disparities in Japan’s total countylevel carbon emissions, per capita carbon emissions, and carbon emission intensity from 2007 to 2015 by Dagum Gini coefficient, and explores the contribution of different carbon emission sources to the regional gap of carbon emissions from the perspective of carbon sources by using Variance Analysis. It is found that the carbon emission indicators of Japan show obvious regional differences, and there is an expanding trend over time. This means that although Japan’s lowcarbon transformation is effective, the processes of lowcarbon development of regions are not harmonious. The regional gap of total carbon emissions mainly comes from the differences among the eight regions, and the unbalanced lowcarbon development level among county units in different regions is the main factor leading to the regional gap of per capita carbon emissions and carbon emission intensity.

Key words: Japan, carbon emissions, regional disparity, Dagum Gini coefficient decomposition, variance decomposition
