Abstract:

Japan is a country with a higher level of urbanization in the world and its low birth rate and population aging characteristics are obvious. Due to lack of resources, Japanese families advocate low-carbon life concept. With the acceleration of urbanization, China is gradually entering an aging society and the per capita resources are insufficient. Therefore, the Japanese household carbon emissions laws and related experiences should have a certain valuable reference for the establishment of energy-saving emission reduction measures in China. Based on the data from 2001 to 2011 in Japan, this paper built a decomposition model of household carbon emission factors in Japan according to the IPAT-LMDI extension model, which included household size, housing utilization rate, economic development level, carbon emission rate, energy consumption structure, and energy consumption intensity. Thereafter, the impact of various factors on household carbon emissions in Japan and the sensitivity of Japan’s household carbon emissions to the major factors were further analyzed by two-way statistical approach. The results illustrated that the rising trend of household carbon emissions in Japan is the result of positive driving and inhibitory factors. The carbon emission rate, energy consumption structure, and economic development level are positive driving factors; energy consumption intensity, household size, housing utilization rate are the inhibitory factors. At different period, the sensitivity of household carbon emissions in Japan to different factors was varied in a large degree different. For example, the sensitivity to the household size was relatively higher; while to the economic development level was lower. Household carbon emissions analysis in Japan implies that we should change the perspective of family energy control in the process of urbanization, optimize the family energy structure, control residential growth, scale energy efficiency standards, and raise the awareness and level of low-carbon life.
