METHOD OF MEASURING QUANTITY OF REDUCTION IN CARBON DIOXIDE DISCHARGE AND TRADING SYSTEM OF CARBON DIOXIDE DISCHARGE RIGHT

摘要

PPROBLEM TO BE SOLVED: To support promotion of reduction of carbon dioxide discharge through making the quantity of carbon dioxide discharge reduction clear in a power generation system and the like having a high carbon dioxide discharge reduction effect, and through allowing carbon dioxide discharge right obtained by the system and the like to be tradable. PSOLUTION: By measuring accumulated power generation quantity and accumulated energy utilizing quantity by a fuel cell 10 and the like, by calculating reduction quantity of consumption fossil fuel corresponding to the accumulated power generation quantity or accumulating energy utilizing quantity, and by converting the obtained reduction quantity into carbon dioxide generation quantity, carbon dioxide discharge reduction quantity by the fuel cell and the like is measured. Carbon dioxide discharge right based on the carbon dioxide discharge reduction quantity is opened to public on a communication circuit 40 by a discharge right trading device 20 and make it purchasable from a client terminal 30 via the communication circuit.
