Development of Data on Energy Consumption and CO2 Emissions by Sector for Energy and Environmental Analysis
Summary
In this paper, we developed data on energy consumption and its associated CO2 emissions by sector using the energy balance table in Japan. Many studies have estimated energy consumption and CO2 emissions data by sector, such as the environmental input-output table for example.
However, these data were developed according to the analytical motivations of the analysts involved, and furthermore, there are differences in the methodologies they used. The official statistics have some issues in regard to the estimation of energy consumption and CO2 emissions: there are differences between the years officially announced, and information on the boundaries between sectors is lacking, when it comes to collating the data. Therefore, we considered the yearly energy consumption and CO2 emissions data from the annual official statistics and clarified the problems facing the development of data. Our methodology was applied to the official data which is available from 1990, allowing us to develop historical energy consumption and CO2 emissions data by industrial sector. The energy consumption and CO2 emissions data helped us to develop an analytical model for evaluating the economy and environment. Going forward, we will describe the society to which low-carbon technologies will lead us in the future, using our analytical model together with the developed data.
