Description

[Technical Field]

[0001] The present invention relates to a CO2 emission calculation support system and a collaborative processing method for the CO2 emission calculation support system in which each data terminal of each company is connected to a server device via a platform that provides a service for calculating CO2 emissions via a specified communication medium, and in which each company collaborates to support the calculation process of CO2 emissions. [Background technology]

[0002] Prior to this application, the applicant filed a patent application for a CO2 emissions calculation support system that can provide a service to support commercial transactions that deepen interest in carbon neutral activities by using accounting data obtained from each company when providing products or services to derive the amount of CO2 emissions consumed, and publishing a CFP tailored to each product or service on an EC page on an EC server that mediates the provision of each product or service, and clearly indicating to consumers the CO2 emissions emitted in each company's manufacturing process in numerical form. Meanwhile, the following Patent Document 1 has been published as a system that supports this type of data processing.

[0003] In this patent document 1, in order to reduce the burden of performing CO2 emission calculation processing using different specifications (multiple calculation parameters) for buyers and suppliers in CO2 emission calculation processing involving multiple companies, a calculation specification screen formulated by the buyer is presented to the supplier, and the buyer and supplier can work together with simple operations to perform highly accurate CO2 emission calculation processing. [Prior art documents] [Patent documents]

[0004] [Patent Document 1] Patent No. 7315191 Summary of the Invention [Problem to be solved by the invention]

[0005] However, while Patent Document 1 allows the calculation process for SCOPE 3 emissions to be performed based on one registered company, in cases where a complex support relationship is organized such that multiple subsidiary companies that branch off from a single manufacturing company work together to manufacture products, the relationship between the parent company, which should be managed in the database of the server device, and the subsidiary companies is not closely linked, and it has been pointed out that this poses a problem in that it is not possible to calculate CO2 emissions on a company-by-company or site-by-site basis.

[0006] Furthermore, because there is no established method for multiple subsidiary companies that branch off from a parent company to work together, it was pointed out that simply linking existing systems would make it difficult to develop a service that objectively visualizes CO2 emissions based on the collaborating companies.

[0007] In addition, when a partner company leaves the network, the CO2 emissions of the registered company will also show different indicators, but it has been pointed out that the system has little flexibility in changing its configuration in response to objective fluctuations in CO2 emissions.

[0008] The present invention has been made to solve the above-mentioned problems, and aims to provide a CO2 emission calculation support system and a collaborative processing method for the CO2 emission calculation support system that can calculate CO2 emissions conforming to SCOPE3 as a collaborative index on a group or base basis, even in a manufacturing environment where a parent company and multiple affiliated subsidiary companies work together to manufacture products. [Means for solving the problem]

[0009] A CO2 emissions calculation support system capable of communicating via a specified communication medium between a data terminal collection consisting of multiple data terminals operated by GHG personnel at each company and a server device that publishes a platform on the cloud that provides a CO2 emissions calculation service to the data terminal collection, wherein the server device comprises: a database that stores and manages identification information that identifies the company itself, which is entered into a collaboration management registration form disclosed on the platform from any data terminal of the data terminal collection; a parent registration means that registers a parent company in the collaboration management registration form registered in the database; a child registration means that registers a subsidiary company that collaborates with the parent company registered in the collaboration management registration form; an editing means that edits a shared linked company list screen that displays the collaboration status of the parent company and the subsidiary company registered in the database; and a service means that provides a linked registration service via the edited shared linked company list screen on the data terminal of the parent company and the data terminal of the subsidiary company. [Effects of the Invention]

[0010] According to the present invention, even in a manufacturing environment where a parent company and multiple affiliated subsidiary companies work together to manufacture products, CO2 emissions conforming to SCOPE3 can be calculated as a linked index on a group or base basis.

[0065] FIG. 15 shows the group management screen, which has a button for adding a new group located at the top left of the screen, and is configured to allow editing and deletion operations for each item manufactured within the group. Also, buttons are provided for deleting a department selected from the group list, for example, a company name (company name) of "Microwave Oven Department," or for adding a company.

[0066] Figure 16 shows an example of a refined search specification screen provided by the server device 1 shown in Figure 1, and is configured so that the CPU 13 starts the refined search process by specifying the registration date, month and year of use, and scope to perform a free-word search of the information registered in the CO2 information database 14.

[0067] 17 to 19 are flow charts illustrating a series of processes for registering affiliated companies in the CO2 emission amount calculation support system according to this embodiment, where S1 to S32 represent the individual steps.

[0068] First, a person in charge of the parent company operates either the first parent data terminal 4-1 to 4-N or the second parent data terminal 2-1 to 2-N to connect to the platform 1A published on the cloud, display the company setting screen shown in Figure 5, and register as a member (S1).

[0069] Next, the parent company's representative operates either the first parent data terminal 4-1 to 4-N or the second parent data terminal 2-1 to 2-N to set a password as the account information required to connect to platform 1A, for example, as displayed on display 311, and performs the login procedure (S2).

[0070] Next, the server device 1 presents the company setting screen shown in Fig. 5 to any of the logged-in first parent data terminals 4-1 to 4-N and second parent data terminals 2-1 to 2-N, and completes the company setting, base setting, and parent user information setting (S3). In response, the parent company's person in charge operates the keyboard 310 to complete input of the company information, such as the company code, company name, and base name.

[0071] As a result, any of the first parent data terminals 4-1 to 4-N and the second parent data terminals 2-1 to 2-N can view a list of companies registered in the CO2 information database 14 of the server device 1 (S7) and accept editing work for their own company information (S8).

[0072] Next, the parent company's representative operates the keyboard 310 or a pointing device (not shown) to select the button for adding a base displayed on the UI screen shown in Fig. 5, and repeats the operation to add their company's base to accept the instruction to add their company's members (S9, S10). As a result, the base information is linked to the already registered company code and updated in the CO2 information database 14.

[0073] Meanwhile, from step S3 onwards, the person in charge of the parent company operates the keyboard 310 or a pointing device (not shown) to display the form data for calculating emissions presented on the platform 1A on the display 311, and inputs the company's emissions with reference to the emission source units (S4). As a result, the CO2 emissions automatically calculated by the server device 1 are displayed in a list of emissions linked to the company code in the CO2 information database 14 (for example, the UI screen shown in Fig. 10) (S5).

[0074] Then, the parent company's representative operates the keyboard 310 or a pointing device (not shown) to go to the analysis page on the UI screen shown in Figure 10 presented on the platform 1A and check the company's CO2 emissions (which are assumed to be automatically calculated by the server device 1) (S6).

[0075] Meanwhile, steps S7 and onwards correspond to the task of registering a subsidiary company that will collaborate with the parent company, and the parent company's staff operates the keyboard 310 or a pointing device (not shown) to display the UI screen shown in Figure 6 presented on the platform 1A on the display 311 and input instructions to collaborate with other companies (S11).

[0076] Specifically, this corresponds to the task of registering a subsidiary company that will collaborate with the parent company. The person in charge at the parent company operates the keyboard 310 or a pointing device (not shown) to input the necessary email address, company name, etc., and presses the button to invite other companies (S12), which then executes a process to send the invitation to the entered address (S13).

[0077] In response to this, an invitation email sent to, for example, Company B as a subsidiary company is received (S14). In response to this, the person in charge of the invited subsidiary company operates the keyboard 310 or a pointing device (not shown) to connect to the URL presented by the platform 1A, and a UI screen for registering the subsidiary company similar to the UI screen shown in Fig. 6 is displayed on the display 311, and the person in charge accepts input of information identifying the subsidiary company and executes member registration (S15).

[0078] Next, as in the case of registering the parent company, after setting a password for connecting to platform 1A, when login processing is accepted (S24), the UI screen shown in Fig. 7 is displayed on the display 311 of the subsidiary company. In response to this, the person in charge of the subsidiary company operates the keyboard 310 or a pointing device (not shown) to set company settings, base settings, and parent user (parent company) information (S25).

[0079] Next, it is determined whether a request for approval of the company collaboration has been received from Company A (parent company), and if it is determined that an instruction to approve has been received, the process of registering the collaboration approval in the CO2 information database 14 is executed (S26).

[0080] As a result, Company B (subsidiary company) executes a process to share its own emissions from the emissions list with Company A (S32). After that, Company A and Company B can share their coordinated CO2 emissions on the CO2 information database 14 in the CO2 emissions management process.

[0081] In this way, after the collaborative process in the CO2 emission calculation process between Company A and Company B is completed (S27), the person in charge at Company A, or the person in charge at the parent company, operates keyboard 310 or a pointing device (not shown) to display the CO2 emission list presented on platform 1A (for example, the UI screen shown in Figure 16) on display 311, shares the CO2 emission amount with Company B (S28), and proceeds to step S4 or step S7.

[0082] Also, in step S11, when the operation to add another company is performed on the UI screen shown in Figure 6 (S16), the person in charge of the parent company operates the keyboard 310 or a pointing device (not shown) to enter the company code and press the add button, and the collaboration process with the other company is executed (S17).

[0083] Next, when Company B receives a request from server device 1 for approval of company collaboration from Company A and presses the approval button on the UI screen displayed on display 311 (S18), Company B approves, and the process of collaborating with Company A is completed (S19), and the process proceeds to step S29.

[0084] On the other hand, from step S7, when the user in charge presses the button for group management displayed in the group management unit on the UI screen shown in Figure 5 (S20), a group creation process is executed in which the parent registration unit 16-1 and the child registration unit 16-2 work together to manage the data of each company registered in the CO2 information database 14 (S21), and the server device 1 executes the service unit 16-4 at the request of the person in charge of the parent company to move to a page for analyzing CO2 emissions (S22), and presents the UI screen shown in Figure 13 on the display 311 of either the first parent data terminal 4-1 to 4-N or the second parent data terminal 2-1 to 2-N.

[0085] Then, when the person in charge of either the first parent data terminal 4-1 to 4-N or the second parent data terminal 2-1 to 2-N inputs the analysis target and target year and month, the upload unit 303-5 executes a predetermined process.

[0086] As a result, the CPU 13 of the server device 1 executes the indexing unit 16-5 to execute a process of analyzing the CO2 emissions for each group registered in the CO2 information database 14 (S23). When this process is completed, the server device 1 proceeds to step S7.

[0087] When the server device 1 proceeds from step S19 to step S29, the group setting unit 303-1 of Company B's data terminal collaborates with the parent company, and when the collaboration button with the parent company is operated on the UI screen shown in Figure 11, a process is executed to share CO2 emissions with Company A from the emissions list, for example (S29).

[0088] As a result, the CO2 emissions of Company A and Company B are shared, and thereafter, the person in charge at Company A can view Company B's CO2 emissions on the display 311 with simple operations (S30), and when they select Company B as a required item on the UI screen shown in Figure 13, the server device 1 checks the latest information on the CO2 emissions of Company B linked to Company A in the CO2 information database 14 (S31), and completes the series of CO2 emissions calculation and viewing processes carried out in collaboration between the companies.

[0089] 20 to 23 are diagrams illustrating the system configuration of the CO2 emission calculation support system according to this embodiment, in which CO2 emission amounts are linked between a plurality of companies and their respective bases.

[0090] In this example, Company C shown in Figure 20 is organized into locations A and B, and location A is composed of companies C_A and C_B, while location B is composed of companies C_C and C_D.

[0091] Similarly, Company A shown in FIG. 21 is organized from base A, and base A shows a company organization including companies A_A to A_D and company A_E. Also, Company B shown in FIG. 22 shows a company organization that includes base A, is made up of companies B_A to B_C, and also includes company B_D.

[0092] Furthermore, Company D shown in Figure 23 includes locations A to C, with location A consisting of companies D_A and D_B, location B including company D_C, and location C including company D_D.

[0093] Even with a company structured in this way, the person in charge at each of companies A to D can view the information that can be shared by operating the UI screen shown in Figure 13, simply by entering the company code corresponding to each location and the company at each location, and the CO2 emissions of each location can be automatically calculated and viewed.

[0094] [Effects of the first embodiment] According to this embodiment, even in a product manufacturing environment where a parent company and multiple affiliated subsidiary companies work together to manufacture products, CO2 emissions conforming to SCOPE3 can be calculated as a linked index on a group or base basis.

[0095] Second Embodiment In the above embodiment, a system was described that assumes a case where an increase in subsidiary companies is linked to one parent company. However, even when a manufacturing business partnership is dissolved, the system may be configured to have a function in which the editing unit 16-3 automatically edits the CO2 emission figures managed in the CO2 information database 14 in response to the deletion of a subsidiary company registered in the above-mentioned collaboration management registration form.

[0096] [Effects of the second embodiment] According to this embodiment, even when a partner company leaves the network, the CO2 emissions of registered companies will show different indicators, but it is possible to build a highly flexible and flexible system that can follow objective fluctuations in CO2 emissions. [Industrial Applicability]

[0097] In the above embodiment, even in a manufacturing environment where a parent company and multiple affiliated subsidiary companies work together to manufacture products, it is possible to calculate CO2 emissions conforming to SCOPE 3 on a group or base basis as a linked indicator, and to construct a CO2 emissions calculation support system that includes SCOPE 1 and SCOPE 2.
