A quantitative energy supply system toward a Zero Carbon (herein after abbreviated as ZC) society in 2030 and 2050 derived from our design platform has been developed. Furthermore, the relationships between GDP and CO2 emissions have been clarified quantitatively under the various conditions by applying our proprietary system with the integration of newly developed input-output table and above-mentioned energy supply system. CO2 emissions from daily life field can approach ZC relatively easily by using the ZC power supply. However, it is not easy to reduce COâ‚‚ emissions from the manufacturing field to zero. The relationships between GDP and CO2 emissions in 2050 shall strongly depend on the industrial and social structure. By changing these structures under different conditions, the pathways to a bright future ZC society could be visualized.
