Outline of Final Research Achievements

The material flow of "materially retained" carbon derived from basic petrochemicals and timber in Japanese economic activities was visualized by the input-output based material flow analysis. As a result, we obtained that 6,300 kt and 7,900 kt of carbon were introduced to Japanese economy as a part of products in 2011 derived from the basic petrochemicals and timber, respectively. This amount of carbon corresponds to 4.1% of annual CO2 emission in 2011. It implies that if we use the carbon containing products as long as possible to prevent the carbon from emission in the waste treatment stage, we would be able to avoid substantial amount of CO2 emission.
