Abstract: A control device reads power consumption, information on the delivery number and weight of a first product set, and information on the delivery number and weight of a second product set from a storage device. The control device proportionally divides the power consumption. The control device reads a first conversion formula from the storage device, and calculates CO2 emissions from transportation of the first product set from an A station to a B station and CO2 emissions from transportation of the second product set from the A station to the B station by substituting the power consumptions, into the first conversion formula.

Abstract: A management device includes a communication device and a control device. The communication device is configured to communicate with a moving object configured to transport a product from an upstream company to a downstream company. The control device is configured to calculate CO2 emissions emitted by transportation of the product based on an amount of energy consumed by the moving object from a transportation start time point to a transportation completion time point of the product.

Abstract: A management method for managing a CO2 emission amount to be emitted by producing a product, includes: reading out a first CO2 emission amount that is a CO2 emission amount per unit weight of a first raw material and a second CO2 emission amount that is a CO2 emission amount per unit weight of a second raw material; and calculating the CO2 emission amount of the product based on a CO2 emission amount to be calculated from the first CO2 emission amount and from a weight of the first raw material used to produce the product, and a CO2 emission amount to be calculated from the second CO2 emission amount and from a weight of the second raw material used to produce the product.

Abstract: A management method for management of a CO2 emission amount emitted by production of a product in a production line where a first product and a second product are produced includes acquiring a power consumption amount consumed in the production line for a predetermined period, and calculating a CO2 emission amount for each product by allocating the power consumption amount based on a ratio of a total work time required to produce the first product in the production line during the predetermined period and a total work time required to produce the second product in the production line during the predetermined period.
