This study explores national and regional carbon emission patterns in Japan between 2007 and 2015, a period impacted by the 2008 financial crisis and the 2011 Tohoku earthquake. Following the 2011 earthquake, previously decreasing regional emissions increased in most regions due to growing coal use. The study uses the Logarithmic Mean Divisia Index (LMDI) to decompose emission drivers, finding initial economic impacts after 2008, followed by energy structure changes after 2011, and then economic and energy intensity effects. The findings offer insights into how events affect emissions at different scales and inform climate change mitigation strategies.
