Our work
Providing the inventory database, IDEA
For companies and organizations to decarbonize, it is first necessary to accurately understand how much greenhouse gas emission is generated and in what situations in each business. LCA Promotion Consortium will provide IDEA.
IDEA Ver.3.0 is a database that can quantify the environmental loads (e.g., CO2, NOx, SOx, PM2.5, chemical substances such as As, Cd, Cr, and Pb, and resource consumption such as iron and copper, etc.) of all products and services in Japan, including about 4,700 agricultural products, industrial products, energy, and waste disposal. It is a database that can quantify the environmental impact per unit of production. In addition to providing numerical values of the environmental impact per unit of production, the database also includes input and output data for the manufacturing process of each product. Since the inventory data changes over time, we plan to release updated data yearly.

What is IDEA?
▶Features of IDEA
- It adopts the hierarchical structure ensures comprehensiveness. (At least some data is available.)
- It is the database, which is the Japanese representative.
- It adopts unit process data as much as possible to maintain a high level of transparency.
- Data quality is assessed to ensure reliability.
▶How to create the database
- Creation of accumulated inventory data using statistics
Energy statistics
Industrial statistics, other dynamic statistics
Input-Output table - Creation of accumulated inventory data using process data
Survey of actual processes
Use of process simulators - Development of data based on the existing inventory database
Collection of data from the literature.
▶Number of IDEA’s datasets
The world’s largest number of datasets (approximately 4,700 datasets)
