It is important to transfer of good policies from regions that have achieved decarbonization first to other region. This study aims to gain insight into the current status and efforts of municipalities to decarbonize their economy through the use of national open data in the context of inter-municipal comparisons. We analyzed the current status of emission reductions, their relationship to target progress, and efforts to reduce emissions. The analysis showed that 366 municipalities had already met their targets. This represents 37.2% of the total. Looking at the top emission reduction municipalities by prefecture, we see that western Japan prefectures such as Tokushima and Miyazaki prefectures have a high percentage of municipalities with high reduction rates, while eastern Japan prefectures such as Miyagi and Akita prefectures have a low percentage of municipalities. There is no statistically significant difference between the rate of CO2 emission reductions and efforts such as global warming prevention ordinances and municipalities' master plans. There is also no correlation between the emission reduction rate and the rate of population decline, the total floor space of administrative facilities, or the financial capability index. It is expected that this research will develop as the scope of national open data disclosure is expanded in the future.
