"Carbon dioxide emission based on the Input-Output analysis" was published for the purpose of compiling the carbon dioxide emission intensity classified by sectors. The data is derived from the study on comprehensive evaluation of technological measures to arrest global warming financed by the fund of global environmental research promotion.

CO2 emissions from burning fossil fuels, one of the cause of global warming, are connected with every socio-economic activity. It's necessary to grasp the emissions quantitatively from each section for assessing the effect of technical countermeasures.

This database is based on the Japan's input-output table which is perceived as one of the most excellent ones in the world. It covers annual CO2 emission classified minutely by sectors. The data can be applied for countermeasure of the emission source. It's also useful as a basic data for

life-cycle assessment (LCA), because it shows the emission intensity from the raw material production.

The database includes inventories of the emission intensity(amount of emission per unit price) in every five years from 1975 to 1990, classified by sectors on the producer price basis and the consumer price basis.

When discussing the emission responsibility of a specific sector, it's necessary to take into consideration not only the direct emissions from energy use by sectors, but also the emissions caused by the induced activities in different sectors.

This database will be useful for the calculation of the direct and indirect emissions attributed to the activities in sectors. You can also calculate CO2 emissions on each level; Government, Local governments, industries, and households.

CD-ROM disks formatted in MS Excel are contained.
