Abstract
This paper introduces indicators for evaluating what SDGs have achieved in the context of a recycling-oriented society with lifecycle inventory databases serving as the foundation. It also provides an explanation using a general outline for IDEA, which is based on the bottom-up approach and the I-O analysis method. In addition, the paper shows development of environmental efficiency indicators and explains the evaluation method used by companies employing these indicators. Environmental efficiency indicators (CO2 efficiency indicators) for Japanese industry in the year 2005 are calculated, and quantitatively show the characteristics of the industry. These calculations will be utilized as an indicator for understanding the degree to which SDGs are being achieved. This will also show how well the formation of a recycling-oriented society is progressing for the future and will help in the development of new indicators.
