Abstract: An aspect of an information processing apparatus according to this invention includes an acquisition unit that acquires management information including power information related to one or more types of electric power used in a manufacturing process of a product or component among a plurality of types of electric power of different power generating systems, a calculation unit that calculates a first carbon dioxide emission amount emitted through manufacturing of the product or component based on the power information included in the management information, and an output unit that outputs information related to the first carbon dioxide emission amount.

Abstract: An aspect of an information processing apparatus according to this invention includes an acquisition unit that acquires power sales information related to a plurality of types of electric power of different power generating systems, a generation unit that generates power use support information for supporting selective use of one or more types of electric power from the plurality of types of electric power based on the power sales information, and an output unit that outputs the power use support information.

Abstract: A technique for tracing the amount of CO2 emissions in the distribution process of a tangible object is provided. An information processing device includes: an acquisition unit configured to acquire information on electric power and information on fuel which are used in each of a plurality of steps of a distribution process of a tangible object; a calculation unit configured to calculate an amount of CO2 emissions generated in each of the steps, by using the information on electric power and the information on fuel which are acquired by the acquisition unit; and a storage control unit configured to control a storage unit to store the amount of CO2 emissions generated in each of the steps that is calculated by the calculation unit, in association with the tangible object.

Abstract: An equipment load and a management load imposed on a business operator are reduced, and those who intend to reuse manufactured products can reliably acquire support information necessary for reuse, thereby further promoting the reuse of the manufactured products. A product information management server SV collects attribute information, usage history information, maintenance history information, and CO2 emission information regarding battery modules manufactured by a plurality of storage battery manufacturers, and stores the information in DBs 31-33 in association with each other. Where an information viewing request is received, reuse support information is generated based on the attribute information, usage history information, maintenance history information and CO2 emission information of the corresponding battery module, and the generated reuse support information is transmitted to the requestor.
