First, the extended input-output table was created by adding renewable energy to the published input-output table, and a CO₂ emission factor table was created by associating CO₂ emissions by industrial sector with the extended input-output table. Next, the input-output analysis was conducted by giving changes including the results of the zero-carbon power supply system based on the power generation cost and the materials of renewable energy evaluated by Center for Low Carbon Society Strategy. From the results, Gross Domestic Product GDP and CO₂ emissions were calculated.
　The calculation result was obtained in which both GDP growth and 80% reduction of CO₂ emission were compatible by this method. It is possible to show a scenario of realizing a bright zero-carbon society by conducting input-output analysis with various changes.
