Summary

Stored at the National Institute for Environmental Studies (NIES) are data obtained during studies on structural analysis of CO2 emissions and life cycle inventory analyses. Their results for the period from 1975 to 1990 have been compiled as " Carbon Dioxide Emission Intensity Based on Input-Output Analysis ", published by the Center for Global Environmental Research (CGER) in 1997. Since then, NIES has been collaborating with the Graduate School of Energy Sciences at Kyoto University in applying the data to Life Cycle Assessment (LCA) case studies and adding data on emissions of nitrogen oxides (NOx) and sulfur oxides (SOx) to the intensity database. After the release of the "1995 Input-Output Tables" in May 1999 in Japan, the energy consumption and CO2 emission intensities for 1995 were compiled and entitled "Energy Consumption and Carbon Dioxide Emission Intensities Based on Input-Output Analysis: '95 (beta Edition)", and provisionally opened to the public via a website at Kyoto University. Since then, we have endeavored to improve the quality of the database, taking into account the results of questionnaire surveys and extensive dialogues with its users.

The data on embodied environmental burden intensities were calculated for emissions of major air pollutants (NOx, SOx, and suspended particulate matter), in addition to CO2 emissions and energy consumption, and compiled as a data book entitled "Embodied Energy and Emission Intensity Data for Japan Using Input-Output Tables (3EID)" and as electronically accessible data on a CD-ROM. The main improvements in this publication over the beta Edition are more accurate estimates of fuel consumption, and changes in calorific value and CO2 emission factors for individual fuels, etc., in addition to air pollutant emission intensity. Moreover, this data book also includes the intensities from the "1990 Input-Output Tables", recalculated in the same way as in 3EID, to allow users to make comparisons. The estimation process for intensities is open to users to the maximum extent possible: we believe that data transparency is important for distribution and improvement of the database. We hope the data in 3EID will be of practical use as not only inventory data for LCA but also one of the useful InDexes in the areas of Energy, Economics, and Environmental (3E) studies.
