Development of new version of Inventory Database for Environmental Analysis (IDEA)
1National Institute of Advanced Industrial Science and Technology; 2Kogakuin University
Japanese Life Cycle Inventory Database development has been performed
under the LCA project of five years from 1998 to 2003 with the support
of METI. An LCA project’s database has about 300 data which were
collected by industry association, and about 280 data which were
collected from survey and literature. The inventory data of industrial
association have high reliability as those data were gathered from
actual factories of each industry and were calculated from industry
average. So, we can use it as the background data which are common in
Japan. However, many of these data were set gate to gate as a system
boundary. Accordingly, it is necessary to confirm the data being
connected to the upstream inventory data. If the data could not connect
upstream inventory data, we would use reference data or background data
of LCA software. In addition, the database was collected to target 14
substances (CO2, CH4, HFC, PFC, N2O, SF6, NOx, SOx, dust, BOD, COD,
total phosphorus, total nitrogen, SS). Therefore, we are developing
inventory database (IDEA) which is to advantage of the LCA project data
to the fullest and to increase the environmental impact category. The
total number of inventory data was over 3000 in developed database (IDEA
ver.1). However, IDEA is still under development, so our database is
mainly covered only Japanese industrial activity. It is necessary to
collect inventory data of foreign countries and to consider with import
products. And it is need to increase the environmental impact category
more. And there are wide varieties of data quality of each inventory
data. It is necessary to establish data quality evaluation method and to
modify our data. In addition, it is important to update the database
year by year.
In this presentation, we will discuss about to expand the environmental category of the water footprint data and land use data to IDEA and to update the database. In addition we will discuss about to collect inventory data of foreign countries and data exchanges.
