Description

[Technical field]

[0001] The present disclosure relates to a management device, a management method, and a management system. [Background technology]

[0002] As awareness of environmental issues grows, there is growing interest in the amount of carbon dioxide emitted in the manufacture of products distributed in the market. An upstream company in a supply chain may be requested by a downstream company to which the upstream company supplies the product to disclose the amount of carbon dioxide emitted in the manufacture of the product. The upstream company calculates the amount of carbon dioxide emitted in the manufacture of the product and discloses it to the downstream company. For example, JP 2016-126372 A discloses a method for calculating the amount of carbon dioxide emitted in the transportation process of a product (including materials and parts). [Prior art documents] [Patent documents]

[0003] [Patent Document 1] JP 2016-126372 A Summary of the Invention [Problem to be solved by the invention]

[0004] In this case, downstream companies may be required by law to disclose their calculation methods for carbon dioxide emissions. If such laws and regulations are enacted, it is advisable for downstream companies to be aware of the calculation methods for carbon dioxide emissions of products delivered by upstream companies.

[0005] The present disclosure has been made to solve the above-mentioned problems, and its purpose is to provide a management device, a management method, and a management system that enable downstream companies to recognize the calculation method of carbon dioxide emissions of products delivered by upstream companies. [Means for solving the problem]

[0006] A management device according to a first aspect of the present disclosure is a management device of a first company that manages products delivered from an upstream first company to a downstream second company, and includes a communication unit that communicates with the second company and a calculation unit that calculates a first amount of carbon dioxide emitted by the manufacture of the product by a first calculation method. The communication unit notifies the second company of information including the first amount of carbon dioxide and the first calculation method.

[0007] In the management device according to the first aspect of the present disclosure, as described above, the communication unit notifies the second company of the information including the first carbon dioxide amount and the first calculation method, thereby enabling the downstream company (second company) to recognize the calculation method of the carbon dioxide emission amount of the delivered product of the upstream company (first company).

[0008] In the management device according to the first aspect, the communication unit preferably notifies the second company of the first calculation method together with information including the first carbon dioxide amount. With this configuration, the first carbon dioxide amount corresponding to the product and the first calculation method are notified as a set to the second company. This allows the second company to easily manage the first carbon dioxide amount and the first calculation method by linking them to each other.

[0009] Here, the first company receives an original product that constitutes a product from a third company upstream of the first company, and the third company calculates the second amount of carbon dioxide calculated by the manufacture of the original product using the second calculation method. Therefore, in the management device according to the first aspect, the communication unit preferably notifies the second company of information including the first amount of carbon dioxide and the first and second calculation methods. With this configuration, the second company can recognize the second calculation method for calculating the second amount of carbon dioxide corresponding to the manufacture of the original product in addition to the first calculation method.

[0010] In the management device according to the first aspect, the communication unit preferably notifies the second company of the first calculation method together with the first carbon dioxide amount, and notifies the second company of the second calculation method together with the second carbon dioxide amount. With this configuration, the second company is notified of the second carbon dioxide amount and the second calculation method corresponding to the original product as a set. This allows the second company to easily manage the first carbon dioxide amount and the first calculation method by linking them to each other, and also to easily manage the second carbon dioxide amount and the second calculation method by linking them to each other.

[0011] In the management device according to the first aspect, the first calculation method preferably includes information indicating that the first carbon dioxide amount was calculated based on at least one of the amount of electricity and the amount of energy used in manufacturing the product by the first company. With this configuration, the second company can easily understand the method by which the first carbon dioxide amount was calculated.

[0012] A management method according to a second aspect of the present disclosure is a management method for managing products delivered from a first upstream company to a second downstream company, and includes a calculation step of calculating the amount of carbon dioxide emitted by the production of the product at the first company using a predetermined calculation method at the first company, and a step of notifying the second company of information including the amount of carbon dioxide and the predetermined calculation method from the first company.

[0013] In the management method according to the second aspect of the present disclosure, as described above, the amount of carbon dioxide emitted by the first company in the manufacture of the product and the predetermined calculation method for calculating the amount of carbon dioxide are notified to the second company. This makes it possible to provide a management method that enables the downstream company (second company) to recognize the calculation method for the amount of carbon dioxide emissions of the delivered products of the upstream company (first company).

[0014] A management system according to a third aspect of the present disclosure includes a first management device provided in a first upstream company and a second management device provided in a second downstream company to which a product is delivered from the first company. The first management device calculates the amount of carbon dioxide emitted in the manufacture of the product using a predetermined calculation method, and notifies the second management device of information including the amount of carbon dioxide and the predetermined calculation method.

[0015] In the management system according to the third aspect of the present disclosure, as described above, the amount of carbon dioxide emitted by the production of products in the first company and the predetermined calculation method for calculating the amount of carbon dioxide are notified to the second management device of the second company. This makes it possible to provide a management system that enables the downstream company (second company) to recognize the calculation method for the amount of carbon dioxide emissions of products delivered by the upstream company (first company).

[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 designated by the same reference characters and the description thereof will not be repeated.

[0019] FIG. 1 is a diagram showing a configuration of a management system 1 according to the present embodiment. The management system 1 includes a management device 100 provided in company 101, a management device 200 provided in company 201, and a management device 300 provided in company 301. The companies 101 and 201 are examples of a "second company" and a "first company" in the present disclosure, respectively. The company 301 is an example of a "third company" in the present disclosure. The management device 100 is an example of a "management device" and a "second management device" in the present disclosure. The management device 200 is an example of a "first management device" in the present disclosure.

[0020] The company 101 is located downstream of the company 201. Specifically, the company 101 receives a product 202 from the company 201. The company 201 is located downstream of the company 301. Specifically, the company 201 receives a product 302, which is the source of the product 202, from the company 301. The product that is the source of the product 202 also includes a part that is combined with another part to configure the product 202. A new product 102 manufactured by the company 101 using the product 202 may be delivered to a company downstream of the company 101. Each of the management device 100 and the management device 200 manages the product 202. The product 302 is an example of an "original product" in the present disclosure.

[0021] Moreover, after a product 202 is manufactured in a company 201, it is transported to the company 101 by a transport vehicle 203. Moreover, after a product 302 is manufactured in a company 301, it is transported to the company 201 by a transport vehicle 303.

[0022] The management device 200 includes a processor 210, a storage unit 220, and a communication unit 230. The processor 210 controls the communication unit 230. The processor 210 is an example of a "calculation unit" in the present disclosure.

[0023] The processor 210 calculates the amount of carbon dioxide emitted by the manufacture of the product 202 using a predetermined calculation method. The predetermined calculation method is a method of calculating the amount of carbon dioxide emissions using a predetermined calculation formula based on the amount of electricity used in the manufacture of the product 202 and the carbon dioxide emission coefficient. Note that the above carbon dioxide amount and the predetermined calculation method are examples of the "first carbon dioxide amount" and "first calculation method" of the present disclosure, respectively.

[0024] The storage unit 220 stores the programs executed by the processor 210 as well as information used by the programs (for example, maps, mathematical expressions, and various parameters).

[0025] The communication unit 230 communicates with each of the company 101 (management device 100) and the company 301 (management device 300). The communication unit 230 includes various communication I / Fs.

[0026] Here, a packing box 204 (see FIG. 2) in which a plurality of products 202 are packed is transported from company 201 to company 101. A barcode 205 (see FIG. 2) is attached to the packing box 204.

[0027] The identification unit 110 of the management device 100 is capable of reading (scanning) the barcode 205. That is, the identification unit 110 includes a barcode reader. The identification unit 110 reads the barcode 205 to obtain the identification information of the product 202.

[0028] The identification information of the product 202 includes a delivery number, delivery date and time, information on the delivery company (in this case, company 201), and information on the number of products 202 in the packaging box 204, and so on.

[0029] (Product management method) Next, a method for managing the product 202 by the management system 1 will be described with reference to the sequence diagram of Fig. 3. A method for managing the amount of carbon dioxide emission of the product 202 will be described.

[0030] First, in step S1, company 301 (management device 300) transmits information on the amount of carbon dioxide emitted by the production of product 302 on company 301's production line to company 201 (communication unit 230). Furthermore, management device 300 notifies communication unit 230 of a calculation method for calculating the amount of carbon dioxide emission. Specifically, management device 300 notifies company 201 of the calculation method together with the information on the amount of carbon dioxide emission. Note that the amount of carbon dioxide emission and the calculation method are examples of a "second amount of carbon dioxide" and a "second calculation method" of the present disclosure, respectively.

[0031] Furthermore, the calculation method includes, for example, information indicating that the carbon dioxide emission amount has been calculated based on the amount of electricity used in manufacturing the product 302. The calculation method includes information on a carbon dioxide emission coefficient used in calculating the emission amount. The calculation method may also include information on the amount of electricity used in manufacturing the product 302. The calculation method may also include information on a calculation formula for calculating the carbon dioxide emission amount corresponding to the product 302.

[0032] Also, in step S1, the company 301 (management device 300) may transmit information on the amount of carbon dioxide emitted from the transport vehicle 303 when the product 302 is transported by the transport vehicle 303 to the company 201. Note that the amount of carbon dioxide emitted during the transportation of the product 302 may be transmitted to the company 201 from a company that manages the transport vehicle 303.

[0033] In step S2, company 201 (management device 200) receives the information on the amount of carbon dioxide emissions and the information on the method of calculating the amount of carbon dioxide emissions transmitted in step S1. If there is a company further upstream than company 301, company 201 (management device 200) may also receive the amount of carbon dioxide emitted by the upstream company and information on the method of calculating the amount of carbon dioxide emissions by the upstream company.

[0034] In step S3, the company 201 transports a plurality of products 202 to the company 101 using a transport vehicle 203. The plurality of products 202 are packed in a packaging box 204 (see FIG. 2) and transported. In this embodiment, it is assumed that only the packaging box 204 is transported by the transport vehicle 203.

[0035] In step S4, the management device 100 (identification unit 110) of the company 101 reads (scans) the barcode 205 attached to the packing box 204 transported in step S3. In this way, the management device 100 obtains the identification information of the product 202.

[0036] In step S5, the management device 100 transmits the delivery number included in the identification information acquired in step S4 to the management device 200 (communication unit 230) of the company 201.

[0037] In step S6, the management device 200 (processor 210) of the company 201 tallies (calculates) the amount of carbon dioxide emissions of the product 202 corresponding to the delivery number transmitted in step S5. Specifically, the management device 200 calculates the amount of carbon dioxide emitted by the production of the product 202 based on the amount of electricity consumed by the production line of the product 202.

[0038] In step S7, the management device 200 (communication unit 230) of the company 201 notifies the management device 100 of the company 101 of information on the amount of carbon dioxide emitted in the manufacture of the product 202, which was tallied (calculated) in step S6. In addition, the management device 200 (communication unit 230) notifies the management device 100 of the company 101 of the method for calculating the amount of carbon dioxide emissions used in step S6.

[0039] Specifically, the management device 200 (communication unit 230) notifies the management device 100 of the company 101 of the calculation method together with information on the carbon dioxide emission amount. The calculation method includes information indicating that the carbon dioxide emission amount has been calculated based on the amount of electricity used in manufacturing the product 202, and information on the carbon dioxide emission coefficient used in the calculation. The calculation method may also include information on the amount of electricity used in manufacturing the product 202. The calculation method may also include information on a calculation formula for calculating the carbon dioxide emission amount corresponding to the product 202.

[0040] Furthermore, in step S7, the management device 200 (communication unit 230) notifies the management device 100 of the company 101 of the carbon dioxide emission amount and the calculation method of the carbon dioxide emission amount corresponding to the product 302. Specifically, the management device 200 (communication unit 230) notifies the management device 100 of the calculation method together with the information on the carbon dioxide emission amount.

[0041] In step S8, the management device 100 of the company 101 sums up the amount of carbon dioxide emission corresponding to step S2 and the amount of carbon dioxide emission corresponding to step S6. This calculates the total amount of carbon dioxide emitted for manufacturing the product 202. Note that the amount of carbon dioxide emission corresponding to step S2 may be multiplied by a predetermined coefficient, and the amount of carbon dioxide emission corresponding to step S6 may be summed up. Note that the predetermined coefficient may vary depending on the number (quantity) of products 302 used to manufacture the product 202.

[0042] In step S9, the management device 100 calculates the amount of carbon dioxide emission per product 202. Specifically, the management device 100 divides the total amount of carbon dioxide emission calculated in step S8 by the number of products 202 included in the identification information acquired in step S4.

[0043] In step S10, the management device 100 manages the carbon dioxide emission amount per product 202 calculated in step S9, the product 202, and the above-mentioned calculation method by linking (associating) them with each other. For example, the management device 100 stores a management table 121 (see FIG. 4) in which the product 202, the carbon dioxide emission amount, the above-mentioned calculation method, and the carbon dioxide emission coefficient are linked. FIG. 4 shows an example in which the carbon dioxide emission amount is linked to each product (A, B, and C). In FIG. 4, the products 202 are named products A to C to distinguish them, and the carbon dioxide emission coefficients corresponding to the products A to C are D to F, respectively. The emission coefficients D to F may be equal to each other. In the management table 121, the calculation method of the carbon dioxide emission amount corresponding to the product 302 may also be managed by linking it with the product 202, etc.

[0044] Furthermore, the company 101 (management device 100) associates the carbon dioxide emission amount with each delivered product (see FIG. 4) and manages the carbon dioxide emission amount and the above calculation method for each part. Then, the company 101 calculates the carbon dioxide emission amount of the product 102 by adding the carbon dioxide emission amount for each part used in the product 102 manufactured by the company 101 and the amount of carbon dioxide emitted during the manufacture of the product 102.

[0045] As described above, in this embodiment, the communication unit 230 notifies the company 101 of the amount of carbon dioxide emitted by the company 201 and the calculation method for calculating the amount of carbon dioxide. This allows the downstream company 101 to manage the amount of carbon dioxide emitted by the product 202 and the calculation method by linking them to each other.

[0046] In the above embodiment, an example has been shown in which the calculation method is notified to the company 101 together with the amount of carbon dioxide emitted by the company 201, but the present disclosure is not limited to this. The amount of carbon dioxide and the calculation method may be notified to the company 101 separately.

[0047] In the above embodiment, an example has been shown in which the calculation method is notified to the company 101 together with the amount of carbon dioxide emitted by the company 301, but the present disclosure is not limited to this. The amount of carbon dioxide and the calculation method may be notified to the company 101 separately.

[0048] In the above embodiment, an example was shown in which the calculation method of the carbon dioxide emission amount includes information indicating that it is based on the amount of electricity used during the manufacture of the product 202 (302), but the present disclosure is not limited to this. For example, the calculation method may include information indicating that it is based on the amount of energy used during the manufacture of the product 202 (302). Also, the calculation method may include information indicating that it is based on both the amount of electricity and the amount of energy.

[0049] In the above embodiment, an example in which the barcode 205 is attached to the packing box 204 has been described, but the present disclosure is not limited to this. For example, a barcode may be attached to each of the multiple products 202. Furthermore, code information different from a barcode (for example, a two-dimensional barcode) may be used. Furthermore, a delivery number may be attached to the product 202 or the packing box 204, etc., and the delivery number may be transmitted to the company 201 based on the delivery number being input by an operator in the management device 100.

[0050] In the above embodiment, an example has been described in which the carbon dioxide emission amount corresponding to company 301 and the carbon dioxide emission amount corresponding to company 201 are added up in management device 100 of company 101, but the present disclosure is not limited to this. For example, management device 200 of company 201 may perform the above-mentioned addition process. In addition, management device 200 may calculate the carbon dioxide emission amount per product.

[0051] In the above embodiment, an example has been shown in which the carbon dioxide emission amount corresponding to the company 301 and the carbon dioxide emission amount corresponding to the company 201 are added up, but the present disclosure is not limited to this. The carbon dioxide emission amount corresponding to the company 301 does not need to be taken into consideration.

[0052] In the above embodiment, an example has been described in which the company 101 (management device 100) acquires information on the amount of carbon dioxide emitted in the manufacture and transportation of the product 302 from the company 201, but the present disclosure is not limited to this. The company 101 (management device 100) may acquire information on the amount of carbon dioxide emitted in the manufacture and transportation of the product 302 from the company 301.

[0053] When multiple types of products are transported at the same time, the amount of carbon dioxide emitted in transporting the products may be calculated based on the weight of the products. For example, the amount of carbon dioxide emitted in transporting one product may be calculated based on the ratio of the weight of each product to the total weight of the products loaded on the transport vehicle and the total amount of carbon dioxide emitted during transportation.

[0054] In addition, the history of carbon dioxide emissions corresponding to a product may be managed among multiple companies using a blockchain.

[0055] The embodiments disclosed herein should be considered to be illustrative and not restrictive in all respects. The scope of the present disclosure is defined by the claims, not by the description of the embodiments described above, and is intended to include all modifications within the meaning and scope of the claims.
