Using the published 2015 Input-Output Table [2] and the 2015 Embodied Energy and Emission Intensity Data for Japan (3EID) [3], an extended Input-Output table including renewable energy power generations and a CO₂ emission factor table were prepared. We conducted Input-Output analysis of a number of cases, including changing the electricity supply from 1,000 to 3,000 TWh in the power generation sector, and making changes that are expected to occur in the future in nine sectors that have a large impact on GDP, CO₂ emissions, and electricity demand, as well as changes that are considered necessary to reduce CO₂ emissions. Based on some of the results, we calculated the GDP, CO₂ emissions, and electricity demand in 2030 and 2050, showed that the CO₂ emission reduction target is achievable, and also clarified the issues to achieve the target.
　Using this method, it is possible to evaluate various scenarios by changing the changes made to the Input- Output analysis.
