2003 August Start of trial open of the LCA database (Library) to February, 2004


Objectives of the LCA project in Japan

1. LCA methodologies;To learn/disseminate Practical LCI method.To develop LCI method for recycling.To develop LCIA method

based on endpoint modelling.2. LCI data collection by industrial associations.

3. A network system to show above results.

Inventory study committee WG-1: Inventory data collection

• Transparent and reliable LCI data of around 250 industrial products were collected voluntarily by 22industrial associations of the committee and 34 industrial associations joined in the project.

• System boundary: “Gate to Gate” .• Inventory: 14 flows

(air) CO2, CH4, HFC, PFC, N2O, SF6, NOx, SOx, dust

(water) BOD, COD, total P, total N, SSAISTResearch Center for Life Cycle Assessment

Choice of vertical or horizontal method depends on the condition of material supply, energy

management etc.　→ 　Choice depends on the judgement of each industrial association.

Inventory Data Format-2


Software for inventory data input　　（ General information of sub-system ）


Software for input of the data　　　　


EXAMPLE-This data is not actual-

Characteristics of the database

(1) The system boundary of each product is “Gate to Gate”.

(2) Input products of the downstream processes are not collected completely by the upstream industrial associations.

The data of the product should be complimented by other database for the “Cradle to Gate/Grave”. The database is now called as “LCA Library”.
