[0001] The present disclosure relates to a management device and a management method.

Background Art

[0002] With the increasing awareness of environmental problems, there has been a growing interest in the CO2 emissions generated by the production of products distributed in the market. Upstream companies (upstream companies) in the supply chain may be required by downstream companies (downstream companies) that receive the products to disclose the CO2 emissions generated for the production of the products. The upstream company calculates the CO2 emissions generated for the production of the products and discloses this to the downstream company.

[0003] For example, Japanese Unexamined Patent Application Publication No. 2016-126372 (Patent Document 1) discloses a method for calculating the CO2 emissions in the transportation process of products (including materials and parts). The method for calculating the CO2 emissions in the transportation process disclosed in Japanese Unexamined Patent Application Publication No. 2016-126372 calculates the CO2 emissions corresponding to the purchase amount of the article from a predetermined coefficient table, the industry to which the company belongs, and the purchase amount of the article.

Summary of the Invention

Problems to be Solved by the Invention

[0005] The method for calculating the CO2 emissions in the transportation process disclosed in Patent Document 1 estimates the CO2 emissions based on a predetermined coefficient table and is not actually measured. Therefore, there may be a deviation between the calculated CO2 emissions and the actual CO2 emissions required for transportation from the upstream company to the downstream company. A method for calculating the CO2 emissions in the transportation process with higher accuracy is desired.

[0006] The present disclosure has been made to solve the above problems, and an object of the present disclosure is to accurately calculate the CO2 emissions in the transportation process.

Means for Solving the Problems

[0007] (1) A management device according to an aspect of the present disclosure includes a communication device configured to be communicable with a moving body that transports products from an upstream company to a downstream company, and a control device that calculates the CO2 emissions discharged by the transportation of the products based on the amount of energy consumed by the moving body from the start time to the end time of the transportation of the products.

[0008] According to the above configuration, the CO2 emissions discharged by the transportation of the products are calculated based on the amount of energy consumed by the moving body from the start time to the end time of the transportation of the products. Since the CO2 emissions are calculated based on the actually used amount of energy, the CO2 emissions in the transportation process can be accurately calculated.

[0009] (2) In a certain embodiment, the control device acquires position information and status from the moving body via the communication device, and sets the time when the moving body changes from the sleep state to the startup state within the site of the upstream company as the start time of transportation, and sets the time when the moving body changes from the startup state to the sleep state within the site of the downstream company as the end time of transportation.

[0010] According to the above configuration, the start time and the end time of transportation can be appropriately determined. Therefore, the CO2 emissions in the transportation process can be accurately calculated.

[0011] (3) In a certain embodiment, the moving body includes an internal combustion engine. The control device calculates the CO2 emissions based on the fuel consumption amount consumed by the moving body from the start time to the end time of transportation.

[0012] According to the above configuration, the CO2 emission amount can be calculated based on the fuel consumption amount consumed by the moving body from the start time of transportation to the completion time of transportation, that is, the actually consumed energy amount. Therefore, the CO2 emission amount in the transportation process can be accurately calculated.

[0013] (4) In a certain embodiment, the moving body includes a battery and a driving device that is driven using the power of the battery. The control device calculates the CO2 emission amount based on the power consumption amount consumed by the moving body from the start time of transportation to the completion time of transportation.

[0014] According to the above configuration, the CO2 emission amount can be calculated based on the power consumption amount consumed by the moving body from the start time of transportation to the completion time of transportation, that is, the actually consumed energy amount. Therefore, the CO2 emission amount in the transportation process can be accurately calculated.

[0015] (5) The management method according to another aspect of the present disclosure includes a step of communicating with a moving body that transports products from an upstream company to a downstream company, and a step of calculating the CO2 emission amount emitted by the transportation of the products based on the energy amount consumed by the moving body from the start time of transportation of the products to the completion time of transportation.

Embodiments for Carrying Out the Invention

[0018] Hereinafter, embodiments of the present disclosure will be described in detail with reference to the drawings. In the drawings, the same or corresponding parts are denoted by the same reference numerals and their description will not be repeated.

[0019] FIG. 1 is an overall configuration diagram of the management system 1 according to the present embodiment. The management system 1 is a system for managing the CO2 emission amount discharged by the production of products. The management system 1 includes a management device 2 belonging to Company A, a management device 3 belonging to Company B, and a management device 5 belonging to Company C that conducts a transportation business using a transport vehicle 6. Company A and Company B form a supply chain. Company A is an upstream company of Company B in the supply chain. Company A delivers a product 71, which is its own product, to Company B. The product 71 is packed in a packing box 7 and transported from Company A to Company B by the transport vehicle 6. In the present embodiment, the product 71 is an electronic component. Note that the product 71 is not limited to being an electronic component and may be various raw materials. Also, the product 71 is not limited to being packed in the packing box 7 and transported, and the product 71 may be loaded onto the transport vehicle 6 and transported. The product 71 may be, for example, parts such as an engine or a door of an automobile.

[0020] FIG. 2 is a diagram showing an example of the packing box 7. A barcode 8 is attached to the packing box 7. Note that instead of the barcode 8, a QR code (registered trademark) may be attached to the packing box 7. When the product 71 is not packed in the packing box 7, for example, the barcode 8 may be directly attached to the product 71.

[0021] Referring again to FIG. 1, the management device 2 of Company A manages the CO2 emission amount Q1 emitted by the production of product 71. The CO2 emission amount Q1 emitted by the production of product 71 includes the CO2 emission amount Q1a required to produce product 71 using raw materials in the production line of Company A, and the CO2 emission amount Q1b emitted by the production of the raw materials. Company A purchases the raw materials from an upstream company (not shown) in the supply chain. The management device 2 calculates the CO2 emission amount Q1b based on the information reported by the upstream company that is the supplier of the raw materials (CO2 emission amount per unit weight of the raw materials). The management device 2 adds the CO2 emission amount Q1b to the CO2 emission amount Q1a to calculate the CO2 emission amount Q1, and manages this. Note that hereinafter, the CO2 emission amount Q1 is also referred to as the "CO2 emission amount Q1 in the production process".

[0022] The management device 2 includes a control device 21, a storage device 22, and a communication device 23. The control device 21, the storage device 22, and the communication device 23 are connected to a bus (not shown).

[0023] The control device 21 is constituted by, for example, an integrated circuit including a CPU (Central Processing Unit). The control device 21 includes a memory and executes various programs stored in the memory. The various programs include an operating system and the like. The memory includes, for example, a ROM (Read Only Memory) that stores the various programs, and a RAM (Random Access Memory) that functions as a working memory and temporarily stores various data necessary for the execution of the various programs.

[0024] The memory device 22 stores a first conversion formula (first conversion information) for converting the power consumption into CO2 emissions. The first conversion formula may be, for example, one that multiplies the power consumption by a first CO2 emission coefficient. The first CO2 emission coefficient may be, for example, a value published by a country, government, operator, etc. The first CO2 emission coefficient may be set for each type of power (such as whether it is renewable energy or not). The first conversion formula stored in the memory device 22 is updated by the control device 21, for example, as the published first CO2 emission coefficient is updated.

[0025] The communication device 23 is configured to be communicable with the management device 3. The communication between the communication device 23 and the management device 3 is performed via, for example, the Internet or the like. Also, the communication device 23 is configured to be communicable with a management device (not shown) of an upstream enterprise in the supply chain. The communication between the communication device 23 and the management device of the upstream enterprise is performed via, for example, the Internet or the like.

[0026] The control device 21 causes the memory device 22 to store, for example, the CO2 emissions per unit weight of the raw materials received from an upstream enterprise in the supply chain. The control device 21 divides, for example, the weight of the raw materials used to produce a lot of products 71 (assuming the raw materials are the starting materials) by the number of products 71 included in the lot to calculate the weight of the raw materials used per unit number of products 71. The control device 21 multiplies the weight by the CO2 emissions per unit weight of the raw materials to calculate the CO2 emissions Q1b emitted by the production of the raw materials, and stores this in the memory device 22.

[0027] The control device 21 also acquires the amount of power (power consumption E) consumed in a production line (not shown) for producing the product 71. The power consumption E in this embodiment is the amount of power consumed in the production of one lot. The power consumption E may be measured by a power meter (not shown) provided on the production line, or may be measured by the management device 2. The power consumption E may be, for example, the power consumed in a factory building in which the production line is installed. The power consumed in the factory building may include, for example, power for operating all the equipment related to the production of the product, such as air conditioning, lighting, part transport vehicles (forklifts, etc.), conveyors on the production line, impact wrenches, and assembly devices. For example, in the case where a plurality of production lines are installed in a factory building, the power consumed in the production line may include power for operating the equipment related to the production of the product produced in the production line, and may not include power for operating the equipment related to the production of the product produced in the other production lines.

[0028] The control device 21 reads out the conversion formula from the storage device 22. The control device 21 inputs the power consumption E into the conversion formula to calculate the amount of CO2 emissions Qcal emitted on the production line in the production of one lot. The control device 21 divides the amount of CO2 emissions Qcal by the number of products 71 included in one lot to calculate the amount of CO2 emissions Q1a required to produce the products 71 using raw materials on the production line of company A.

[0029] The control device 21 adds the CO2 emission amount Q1a and the CO2 emission amount Q1b to calculate the CO2 emission amount Q1 in the production process. Specifically, the CO2 emission amount Q1 in the production process is expressed by the following formula (1).

[0030] Q1=Q1a+Q1b...(1) The control device 21 stores the amount of CO2 emissions Q1 in the production process in the storage device 22. The control device 21 transmits the amount of CO2 emissions Q1 in the production process to the management device 3 via the communication device 23 upon delivery of the product 71 to the company B or upon request from the company B.

[0031] The management device 3 includes a control device 31, a storage device 32, a communication device 33, and a reading device 34. The control device 31, the storage device 32, the communication device 33, and the reading device 34 are connected to a bus (not shown).

[0032] The control device 31 is constituted by, for example, an integrated circuit including a CPU. The control device 31 includes a memory and executes various programs stored in the memory. The various programs include an operating system and the like. The memory includes, for example, a ROM that stores the various programs, and a RAM that functions as a working memory and temporarily stores various data necessary for the execution of the various programs.

[0033] The storage device 32 stores the CO2 emission amount Q of the product 71 purchased from Company A (upstream company). The CO2 emission amount Q is represented by the following formula (2) and includes the CO2 emission amount Q1 in the production process and the CO2 emission amount Q2 in the transportation process.

[0034] Q = Q1 + Q2 ··· (2) Details of the CO2 emission amount Q2 in the transportation process will be described later. The CO2 emission amount Q2 in the transportation process is the CO2 emission amount discharged for transporting the product 71 from Company A to Company B. The control device 31 acquires the CO2 emission amount Q2 in the transportation process from the management device 5 via the communication device 33.

[0035] The communication device 33 is configured to be able to communicate with the management device 2 and the management device 5. The communication between the communication device 23 and the management device 2 and the management device 5 is performed via, for example, the Internet or the like.

[0036] The reading device 34 is configured to be able to read the barcode 8. The reading device 34 includes a barcode reader. As shown in FIG. 2, the packing box 7 is attached with a barcode 8. The reading device 34 acquires the product information of the product 71 by reading the barcode 8.

[0037] The product information of product 71 includes information such as the delivery number, identification number, delivery date and time, information of the supplier company (Company A in this embodiment), and the number of products 71 in the packing box 7. The control device 31 causes the storage device 32 to store the product information read by the reading device 34.

[0038] The control device 31 transmits the delivery number (or identification number) included in the product information to the management device 2 of Company A via the communication device 33. In this embodiment, the transmission of the delivery number (or identification number) means a request for disclosure of the CO2 emission amount Q1 in the production process. As a response to the disclosure request, the control device 31 acquires the CO2 emission amount Q1 in the production process from the management device 2 via the communication device 33.

[0039] In addition, the control device 31 acquires the CO2 emission amount Q2 in the transportation process from the management device 5 via the communication device 33. Specifically, the control device 31 acquires the total CO2 emission amount Q2total emitted by the transportation of the packing box 7 from the management device 5, divides the CO2 emission amount Q2total by the number of products 71 in the packing box 7, and calculates the CO2 emission amount Q2 in the transportation process. The control device 31 associates the CO2 emission amount Q1 in the production process and the CO2 emission amount Q2 in the transportation process with the identification number (or delivery number) of the product 71, and stores them in the storage device 32 as the CO2 emission amount Q of the product 71.

[0040] The management device 5 manages the transport vehicle 6. In the present embodiment, the transport vehicle 6 is a vehicle equipped with an internal combustion engine (not shown). Also, although not shown in any of the transport vehicles 6, they are equipped with a communication device and a GPS (Global Positioning System) receiver. The communication device may be, for example, a DCM (Data Communication Module). The transport vehicle 6 is configured to be communicable with the management device 5 via the communication device. The transport vehicle 6 is configured to transmit position information, fuel consumption information, and status information to the management device 5 at a predetermined cycle. The status information is information indicating whether the traveling system of the transport vehicle 6 is in an activated state or a sleep state. The fuel consumption information indicates the amount of fuel consumed by the transport vehicle 6 during a predetermined cycle. The fuel consumption information may be information on the remaining amount of fuel. The transport vehicle 6 corresponds to an example of the "mobile body" according to the present disclosure.

[0041] The management device 5 includes a control device 51, a storage device 52, and a communication device 53. The control device 51, the storage device 52, and the communication device 53 are connected to a bus (not shown).

[0042] The control device 51 is constituted by, for example, an integrated circuit including a CPU. The control device 51 includes a memory and executes various programs stored in the memory. The various programs include an operating system and the like. The memory includes, for example, a ROM that stores the above various programs, and a RAM that functions as a working memory and temporarily stores various data necessary for the execution of the various programs.

[0043] The storage device 52 stores various information (position information, fuel consumption information, and status information) received from the transport vehicle 6. Also, the storage device 52 stores the position information of Company A and the position information of Company B. That is, the storage device 52 stores the position information of the source of the goods transported by the transport vehicle 6 (Company A in the present embodiment) and the position information of the destination of the goods (Company B in the present embodiment).

[0044] In addition, the storage device 52 stores a second conversion formula (second conversion information) for converting the fuel consumption into CO2 emissions. The second conversion formula may, for example, multiply the fuel consumption by a second CO2 emission coefficient. The second CO2 emission coefficient may be a value published by, for example, a country, a government, an operator, etc. The second CO2 emission coefficient may be set for each type of fuel (such as gasoline, light oil, biodiesel, etc.). The second conversion formula stored in the storage device 52 is updated by the control device 51, for example, as the published second CO2 emission coefficient is updated.

[0045] The communication device 53 is configured to be communicable with the transport vehicle 6 and the management device 3. The communication between the communication device 53 and the transport vehicle 6 and the management device 3 is performed via, for example, the Internet or the like.

[0046] The control device 51 calculates the CO2 emissions Q2total in the transport process, which is the CO2 emissions discharged by the transport vehicle 6 for transporting the product 71 (packaging box 7) from Company A to Company B. Specifically, the control device 51 converts the fuel consumption of the transport vehicle 6 from the start time point T1 to the end time point T2 of the transport process into CO2 emissions using the above second conversion formula, and sets the converted value as the CO2 emissions Q2total in the transport process. The control device 51 divides the CO2 emissions Q2total by the number of products 71 in the packaging box 7 to calculate the CO2 emissions Q2 per unit number of the product 71 in the transport process.

[0047] The control device 51 determines the start time point T1 and the end time point T2 based on the position information and status information received from the transport vehicle 6. The control device 51 determines the time point when the status information of the transport vehicle 6 switches from the sleep state to the startup state within the site 29 of Company A as the start time point T1. The control device 51 determines the time point when the status information of the transport vehicle 6 switches from the startup state to the sleep state within the site 39 of Company B as the end time point T2.

[0048] The control device 51 transmits the CO2 emissions Q2 in the transport process to the management device 3 of Company B via the communication device 53.

[0049] Figure 3 is a functional block diagram of the control device 21 of the management device 2, the control device 31 of the management device 3, and the control device 51 of the management device 5. The control device 21 includes a receiving unit 211, a reading unit 212, and a reporting unit 213. The control device 31 includes a receiving unit 311, a storage unit 312, and a requesting unit 313. The control device 51 includes a determining unit 511, a monitoring unit 512, an arithmetic unit 513, and a reporting unit 514. Each of the control devices 21, 31, and 51 realizes the functions of each unit by executing a program stored in a memory. It should be noted that each of the above units can also be realized by, for example, dedicated hardware (electric circuit).

[0050] The determining unit 511 acquires position information and status information from the transport vehicle 6 at a predetermined cycle, and uses this information to determine the start time point T1 and the completion time point T2 of the transport process. The determining unit 511 specifies the position of the transport vehicle 6 based on the position information. The determining unit 511 determines the start time point T1 as the time point when the status information of the transport vehicle 6 switches from the sleep state to the activated state within the site 29 of Company A. The determining unit 511 notifies the monitoring unit 512 that the start time point T1 has been determined. The determining unit 511 determines the completion time point T2 as the time point when the status information of the transport vehicle 6 switches from the activated state to the sleep state within the site 39 of Company B. The determining unit 511 notifies the monitoring unit 512 that the completion time point T2 has been determined.

[0051] The monitoring unit 512 acquires information on fuel consumption from the transport vehicle 6 at a predetermined cycle. The monitoring unit 512 outputs to the arithmetic unit 513 the information on the fuel consumption integrated from the time it receives the notification from the determining unit 511 that the start time point T1 has been determined until it receives the notification that the completion time point T2 has been determined.

[0052] The calculation unit 513 calculates the CO2 emission amount Q2total in the transportation process by using the information on the fuel consumption received from the monitoring unit 512 and the second conversion formula. That is, the calculation unit 513 converts the total value of the fuel consumption accumulated from the start time point T1 to the completion time point T2 into the CO2 emission amount by using the second conversion formula, and sets it as the CO2 emission amount Q2total in the transportation process. The calculation unit 513 outputs the calculated CO2 emission amount Q2total in the transportation process to the reporting unit 514.

[0053] The reporting unit 514 transmits the CO2 emission amount Q2total in the transportation process to the management device 3 of Company B via the communication device 53. Note that the reporting unit 514 transmits the CO2 emission amount Q2total in the transportation process to the management device 3 of Company B in association with the information for identifying the product 71 or the packing box 7. The information for the above identification may be, for example, the delivery number, or the identification number attached to each of the products 71. The identification number may be assigned in lot units (that is, the products 71 of the same lot have the same identification number).

[0054] The receiving unit 311 receives the CO2 emission amount Q2total in the transportation process transmitted from the management device 5 of Company C. The receiving unit 311 outputs the CO2 emission amount Q2total in the transportation process to the storage unit 312.

[0055] The storage unit 312 divides the CO2 emission amount Q2total in the transportation process by the number of products 71 packed in the packing box 7 to calculate the CO2 emission amount Q2 in the transportation process per unit number of the products 71. Then, the storage unit 312 stores the CO2 emission amount Q2 in the transportation process in the storage device 32 in association with the delivery number for identifying the product 71. When a plurality of packing boxes are loaded on the transport vehicle 6, for example, the CO2 emission amount Q2total may be allocated to each packing box based on the number of loaded packing boxes, and then the CO2 emission amount Q2 in the transportation process per unit number may be calculated. Further, the CO2 emission amount Q2total may be allocated to each packing box based on the weight ratio of the packing boxes.

[0056] The receiving unit 311 also notifies the requesting unit 313 that it has received the CO2 emission amount Q2 in the transportation process.

[0057] The requesting unit 313 transmits the identification number (or delivery number) to the management device 2 of Company A via the communication device 33. In response to this, the requesting unit 313 acquires, via the communication device 33, the CO2 emission amount Q1 in the production process of the product 71 from the management device 2 of Company A. The requesting unit 313 outputs the CO2 emission amount Q1 in the production process to the storage unit 312. Note that the requesting unit 313 may transmit the identification numbers of all the products 71 in the packing box 7 to the management device 2 of Company A, or may transmit the delivery number to the management device 2 of Company A.

[0058] The storage unit 312 associates the CO2 emission amount Q1 in the production process with the CO2 emission amount Q2 in the transportation process and stores it in the storage device 32. The CO2 emission amount Q1 in the production process and the CO2 emission amount Q2 in the transportation process are stored in the storage device 32 as the CO2 emission amount Q of the product 71. The association between the CO2 emission amount Q1 in the production process and the CO2 emission amount Q2 in the transportation process can be performed, for example, using the identification number of the product 71. Note that the method of associating the CO2 emission amount Q1 in the production process with the CO2 emission amount Q2 in the transportation process is not limited to the above method, and various known methods can be used.

[0059] The receiving unit 211 receives the identification number (or delivery number) transmitted from the management device 3 of Company B. The receiving unit 211 outputs the identification number (or delivery number) to the reading unit 212.

[0060] The reading unit 212 reads out the CO2 emission amount Q1 in the production process specified by the identification number (or delivery number) from the storage device 22. The reading unit 212 outputs the read CO2 emission amount Q1 in the production process to the reporting unit 213.

[0061] The reporting unit 213 transmits, via the communication device 23, the CO2 emission amount Q1 in the production process to the management device 3. As a result, enterprise B is reported the CO2 emission amount Q1 in the production process of the delivered products.

[0062] Figure 4 is a flowchart showing the procedure of a process for reporting the total CO2 emission amount Q2 in the transportation process, which is executed by the control device 51 of the management device 5. This flowchart starts when it is detected that the transport vehicle 6 has arrived within the premises 29 of enterprise A. Each step (hereinafter abbreviated as "S") of the flowchart shown in Figure 4 will be described for the case where it is realized by software processing by the control device 51, but a part or all of it may be realized by hardware (electric circuit) fabricated within the control device 51.

[0063] In S1, the control device 51 determines whether or not the transportation process of the product 71 (packaging box 7) has started based on the position information and status information received from the transport vehicle 6. Specifically, the control device 51 determines that the transportation process has started when the transport vehicle 6 is within the premises 29 of enterprise A and the status information of the transport vehicle 6 has switched from the sleep state to the startup state. That is, the control device 51 determines the time point when the status information of the transport vehicle 6 has switched from the sleep state to the startup state within the premises 29 of enterprise A as the start time point T1. If the control device 51 determines that the transportation process has not started (status information is in the sleep state) (NO in S1), it waits for the transportation process to start. If the control device 51 determines that the transportation process has started (YES in S1), it proceeds to S2.

[0064] In S2, the control device 51 starts integrating the fuel consumption. The control device 51 integrates the fuel consumption from the start time point T1 to the completion time point T2.

[0065] In S3, the control device 51 determines whether or not the transportation process of the product 71 (packaging box 7) has been completed based on the position information and status information received from the transport vehicle 6. Specifically, the control device 51 determines that the transportation process has been completed when the transport vehicle 6 is within the premises 39 of Company B and the status information of the transport vehicle 6 has switched from the activated state to the sleep state. That is, the control device 51 determines the time point when the status information of the transport vehicle 6 switches from the activated state to the sleep state within the premises 39 of Company B as the completion time point T2. If the control device 51 determines that the transportation process has not been completed (the status information is in the activated state) (NO in S3), it continues to accumulate the fuel consumption. If the control device 51 determines that the transportation process has been completed (YES in S3), it proceeds to S4.

[0066] In S4, the control device 51 ends the accumulation of the fuel consumption. As a result, the fuel consumption from the start time point T1 to the completion time point T2 is accumulated.

[0067] In S5, the control device 51 reads out the second conversion formula from the storage device 52 and calculates the CO2 emission amount Q2total in the transportation process using the accumulated fuel consumption and the second conversion formula.

[0068] In S6, the control device 51 transmits the CO2 emission amount Q2total in the transportation process to the management device 3 of Company B via the communication device 53. As a result, the CO2 emission amount Q2total in the transportation process is reported to Company B.

[0069] The management device 3 of Company B can calculate the CO2 emission amount Q2 per unit of the product 71 in the transportation process by apportioning the reported CO2 emission amount Q2total by the number of products 71 packed in the packaging box 7.

[0070] As described above, in the management system 1 according to the present embodiment, the management device 5 that manages the transport vehicle 6 calculates the CO2 emission amount Q2total in the transport process based on the fuel consumption consumed by the transport vehicle 6 for transporting the product 71 from Company A to Company B. Since the CO2 emission amount Q2total in the transport process is calculated based on the actual fuel consumption, an accurate CO2 emission amount can be calculated. [Modification Example 1] In the embodiment, the start time T1 and the completion time T2 of the transport process were determined based on the position information and the status information acquired from the transport vehicle 6. However, the method for determining the start time T1 and the completion time T2 is not limited to the above. In Modification Example 1, the start time T1 and the completion time T2 of the transport process are determined based on the reading of the transport barcode attached to the packing box 7.

[0071] FIG. 5 is a diagram showing an example of the packing box 7A according to Modification Example 1. In addition to the barcode 8, a transport barcode 9 is attached to the packing box 7A. The transport vehicle 6 is provided with a terminal device (not shown) associated with the transport vehicle 6. When the driver of the transport vehicle 6 receives the packing box 7A from Company A, the driver selects the reception button of the terminal device and reads the barcode 9. The terminal device transmits the reception information and the barcode reading information to the management device 5 together with its own identification number. When the driver of the transport vehicle 6 delivers the packing box 7A to Company B, the driver selects the delivery button of the terminal device and reads the barcode 9. The terminal device transmits the delivery information and the barcode reading information to the management device 5 together with its own identification number.

[0072] The management device 5 (control device 51) can set the time when the reception information is received as the start time T1. The management device 5 (control device 51) can set the time when the delivery information is received as the completion time T2. Which delivery item the reception information belongs to can be determined based on, for example, the barcode reading information. Even in the configuration of Modification Example 1, the same effects as those of the embodiment can be achieved.

[0073] [Modification Example 2] In Embodiment and Modification Example 1, an example where the moving body is a vehicle equipped with an internal combustion engine was described. However, the moving body is not limited to a vehicle equipped with an internal combustion engine. For example, the moving body may be an electric vehicle. In this case, the moving body includes a battery and a driving device that is driven using the power of the battery. When the moving body is an electric vehicle, the CO2 emission amount Q2total in the transportation process may be calculated based on the power consumption of the moving body from the start time point T1 to the completion time point T2. Further, when the moving body is a hybrid vehicle, the CO2 emission amount Q2total in the transportation process may be calculated based on the power consumption and fuel consumption of the moving body from the start time point T1 to the completion time point T2.

[0074] Furthermore, the moving body is not limited to a four-wheeled vehicle and may be a two-wheeled vehicle. Also, the moving body may be an aircraft, a railway, a helicopter, or the like.

[0075] [Modification Example 3] It is also conceivable to form a consortium among the companies included in the management system 1 and share information among the companies using distributed ledger technology. In this case, the management devices 2, 3, and 5 may function as nodes, and a distributed ledger network may be formed with the nodes of other companies included in the supply chain. For example, the management device 2 (node) transmits transaction data including information on the CO2 emission amount Q1 in the production process, which is the reporting target for the downstream company B, to the distributed ledger network. By the management device 3 (node) of company B approving this transaction data, the CO2 emission amount Q1 in the production process is reported to the downstream company. Also, the management device 5 (node) transmits transaction data including information on the CO2 emission amount Q2total in the transportation process, which is the reporting target for the downstream company B, the destination of product 71, to the distributed ledger network. By the management device 3 (node) of company B approving this transaction data, the CO2 emission amount Q2total in the transportation process is reported to the downstream company. By reporting the CO2 emission amount using distributed ledger technology, the tamper resistance of the information can be enhanced.

[0076] The embodiments disclosed herein should be considered illustrative in all respects and not restrictive. The scope of the present disclosure is indicated by the scope of the claims rather than the above description, and it is intended that all modifications within the meaning and scope equivalent to the scope of the claims be included.
