Description

Policy proposal system, policy proposal method and program

[0001] The present disclosure relates to a policy proposal system, a policy proposal method, and a program.

[0002] Traditionally, achieving carbon neutrality has been based on the idea that it is important to promote greenhouse gas (GHG) emission reductions throughout the entire supply chain, not just through the efforts of individual companies. To effectively promote emissions reductions, it is desirable to create a market in which decarbonized and low-carbon products (so-called green products) are more widely selected. To achieve this, it is desirable to more accurately grasp emissions per component (carbon footprint: CFP) and implement measures that will have a significant reduction effect.

[0004] However, conventionally, there is no known technology that can grasp the contribution of each part to GHG reduction in a product made up of multiple parts and propose measures that can clearly achieve GHG reduction effects.

[0005] In view of the above problems, the present invention aims to provide a policy proposal system, a policy proposal method, and a program that are capable of grasping the magnitude of contribution of each part to GHG reduction in a product composed of multiple parts, and proposing measures that will clearly achieve GHG reduction effects.

[0006] In order to solve the above problem, the policy proposal system of an embodiment is a policy proposal system that presents GHG emission reduction measures that propose measures to reduce GHG emissions of products, and is equipped with a CFP information collection unit that collects CFPs for each part that makes up the product, an emission calculation unit that calculates the GHG emissions for each part based on the collected CFPs, a policy decision unit that decides on a proposed policy based on the ratio of primary data and secondary data corresponding to the collected CFPs, and a policy presentation unit that presents the decided policy.

[0007] According to the present disclosure, for products consisting of multiple parts, it is possible to grasp the magnitude of contribution to GHG reduction on a part-by-part basis and propose measures that will clearly achieve GHG reduction effects, thereby making it possible to effectively reduce GHG.

[0009] Next, an embodiment will be described in detail with reference to the drawings. Prior to the description of the embodiment, a conventional problem will be described. When calculating the GHG emissions in the manufacturing process of a certain product, the CFP can be calculated by adding up the emissions of each process.

[0010] More specifically, GHG emissions are calculated by collecting activity data such as the amount of raw materials used and the amount of electricity consumed during production, determining an emission factor corresponding to each activity data, and multiplying these data together. In this case, GHG emissions are calculated based on so-called primary and secondary data corresponding to the product.

[0011] Here, primary data refers to quantified values ​​of processes, activities, and emission factors obtained from calculations based on data actually obtained within the product manufacturing system.

[0012] Secondary data is data that does not meet the requirements of primary data, such as process data in the same product category from the industry, external databases, or papers.

[0013] In this case, when calculating the GHG emissions of one part that constitutes a product based solely on secondary data, the GHG reduction efforts of one or more suppliers involved in the manufacturing process of that part are not reflected. Therefore, in order to reduce the GHG emissions resulting from the manufacturing of that part, it becomes necessary to reduce the activity volume (procurement volume) of that part.

[0014] In contrast, when calculating the GHG emissions of one part that constitutes a product based only on primary data, it is possible to achieve a reduction in GHG emissions without reducing the activity volume (procurement volume) of the part by encouraging one or more suppliers involved in the manufacturing process of the part to make efforts to reduce GHG emissions.

[0015] Generally, the manufacturing process for the parts that make up a single product is a combination of multiple processes, and when calculating GHG emissions, not all data is necessarily primary data; instead, a combination of primary and secondary data is used to calculate GHG emissions.

[0016] Therefore, it was necessary to consider actual GHG reduction measures based on the combination and ratio of primary and secondary data used to calculate GHG gas emissions.

[0017] Here, the handling of primary data and secondary data, which are the prerequisites for implementing GHG reduction measures, will be explained using a specific example.

[0018] Figure 1 is an explanatory diagram of the manufacturing process and primary and secondary data when manufacturing part A. For ease of understanding, as shown in Figure 1(A), the manufacturing process of part A consists of four processes: mining, refining, transportation, and assembly, which are performed in this order.

[0019] Furthermore, as suppliers, it is assumed that part a is manufactured by Company D, who is responsible for mining, Company C, who is responsible for refining, Company B, who is responsible for transportation, and Company A, who is responsible for assembly.

[0020] When calculating the amount of GHG emissions in each process, if only secondary data is available for all processes, the calculated value of GHG emissions will be the sum of the average emissions for each process, as shown in Figure 1(B).

[0021] Furthermore, when calculating the GHG emissions in each process, if primary data is available for all processes, the calculated value of GHG emissions is the sum of the emissions specific to each company corresponding to each process, as shown in Figure 1(C). Furthermore, in actual cases, there may be cases where primary data is available for some processes, but only secondary data is available for other processes.

[0022] More specifically, as shown in Figure 1(D), if there is primary data for the processes corresponding to Company C and Company A, and only secondary data for the processes corresponding to Company D and Company B, the GHG emission output will be the sum of the intrinsic emissions of Company C and Company A and the secondary data for the processes corresponding to Company D and Company B.

[0023] 1(B) to (D) described above, it is considered that Fig. 1(C) is the one that most closely reflects the actual GHG emissions, and Fig. 1(B) is the one that is the furthest from the actual GHG emissions. In other words, when calculating GHG emissions corresponding to multiple processes, it is clear that the higher the proportion of primary data, the more accurately the GHG emissions can be calculated.

[0024] As mentioned above, when calculating the GHG emissions of a part that constitutes a product based solely on secondary data, the GHG reduction efforts of one or more suppliers involved in the manufacturing process of that part are not reflected.

[0025] Therefore, in order to reflect the results of GHG reduction efforts by individual suppliers, it is necessary to collect as much primary data as possible and reduce the proportion of secondary data when calculating GHG.

[0026] Furthermore, in processes for which primary data is available, the current amount of GHG emissions can be known, so by setting and achieving a reduction target for GHG emissions, it is possible to reduce GHG emissions without reducing the activity level of the parts.

[0027] Therefore, in the embodiment, a policy proposal system is provided for proposing to suppliers or set manufacturers, etc., policies for reliably reducing GHG emissions from the present to the future.

[0028] 2 is a block diagram showing the general configuration of a policy proposal system 10. The policy proposal system 10 includes a plurality of user terminals 11, a GHG emission reduction proposal system 12, a database system 13, a CFP simulation system 14, a CFP providing system 15, and a communication network 16.

[0029] Furthermore, external systems (external systems) such as a user terminal 17 of another company and a CFP providing system 18 of another company are connected via a communication network 16. For ease of understanding, only one user terminal 17 and one CFP providing system 18 of another company are shown in Fig. 2, but multiple terminals of each can be connected.

[0030] The user terminal 11 is provided on the side of a user (supplier, set manufacturer, etc.) who wishes to receive a policy proposal, and is a device for specifying a product or part and making a policy proposal request to the GHG emission reduction proposal system 12 via the communication network 16, and for receiving a policy proposal for reducing GHG emissions from the GHG emission reduction proposal system 12 via the communication network 16 as a response.

[0031] For example, the user terminal 11 is configured as a personal computer.

[0032] Based on the received policy proposal request, if a product is the target, the GHG emission reduction proposal system 12 refers to a database system to obtain part information on the parts that make up the product, and also obtains information on where to obtain the corresponding CFP data.

[0033] Then, a collection process of CFP data corresponding to the parts is performed, and the CFP data is acquired as a simulation result by the CFP simulation system 14. As a result, the GHG emission reduction proposal system 12 generates a measure proposal and sends it to the user terminal 11.

[0034] The database system 13 stores part information, which is information about parts that make up a product, information about where to obtain CFP data for each part, and GHG reduction target values ​​for each user, in association with one another.

[0035] The CFP simulation system 14 calculates the CFP of a product when GHG is reduced by simulation and provides it as CFP data. The CFP providing system 15 has a database (not shown) and provides the collected CFP data for a fee or free of charge.

[0036] The other company's user terminal 17, like the user terminal 11, is provided on the side of a user (supplier, set manufacturer, etc.) who wishes to receive a policy proposal, and is a device for specifying a product or part and making a policy proposal request to the GHG emission reduction proposal system 12 via the communication network 16, or for receiving an improvement request, which will be described later, from the GHG emission reduction proposal system 12.

[0037] The other company's CFP providing system 18 provides CFP data corresponding to the requested CFP based on a request from the GHG emission reduction proposal system.

[0038] 3 is a functional block diagram of the GHG emission reduction proposal system 12. The GHG emission reduction proposal system 12 includes a system controller 12A, a storage unit 12B, and a communication interface (IF) unit 12C. The system controller 12A controls the entire GHG emission reduction proposal system 12.

[0039] In this case, the system controller 12A is configured as one or more processors, and functions as a CFP information collection unit 12A1, an emission amount calculation unit 12A2, a policy decision unit 12A3, and a policy presentation unit 12A4. In addition, the communication interface unit 12 functions as a CFP information collection interface in cooperation with the system controller 12A as a processor.

[0040] Here, the processor functioning as the CFP information collection unit 12A1 collects CFP data for each part that constitutes the product for which a measure is proposed. The processor functioning as the CFP information collection unit 12A1 also reduces the processing load and improves processing efficiency by limiting the CFP collection targets to a predetermined number of parts that emit the most GHG among the parts that constitute the product.

[0041] The processor functioning as the emission amount calculation unit 12A2 calculates the GHG emission amount for each part based on the collected CFP data.

[0042] The processor functioning as the measure determination unit 12A3 determines the measure to propose based on the ratio of primary data to secondary data corresponding to the collected CFP data of the parts. The processor functioning as the measure determination unit 12A3 also determines the measure based on the ratio of the GHG emissions of the parts to the GHG emissions of the entire product. The measure presentation unit presents the measure decided by the measure determination unit 12A3 to the user via the communication interface (IF) unit 12C and the user terminal 11.

[0043] The storage unit 12B is configured as a semiconductor storage device such as a ROM, a RAM, or an SSD (Solid State Drive), or an external storage device such as a hard disk drive, and stores various data.

[0044] The communication interface (IF) unit 12C performs communication interface operations between the user terminal 11, the CFP simulation system 14, or the CFP providing system 15 via a communication network 16 configured as the Internet, WAN, etc., and communication interface operations between the user terminal 11, the CFP simulation system 14, or the CFP providing system 15 via a LAN, etc., and a database system.

[0045] Next, the operation of the embodiment will be described. Fig. 4 is an explanatory diagram of GHG emissions. Fig. 4 shows the correspondence between the GHG emissions of one product, the GHG emissions of parts that make up the product, and the primary data and secondary data thereof. Fig. 4(A) schematically shows the GHG emissions GHGX1 of product X1, and its area represents the GHG emissions.

[0046] Figure 4(B) is a diagram showing the GHG emission amounts of the primary data and secondary data used to calculate the GHG emission amount GHGX1 in Figure 4(A). In Figure 4(B), GHGX1-D1 represents the GHG emission amount calculated based on the primary data. GHGX1-D2 represents the GHG emission amount calculated based on the secondary data.

[0047] Furthermore, FIG. 4(C) shows the GHG emissions GHGX1 divided into parts that make up product X1, and further distinguishes between the GHG emissions calculated based on primary data and the GHG emissions calculated based on secondary data.

[0048] 4(C), product X1 is assumed to be composed of eight types of parts, parts A to H. Here, GHGX1-D1A indicates the GHG emission amount calculated for part A based on the primary data. Similarly, GHGX1-D2A indicates the GHG emission amount calculated for part A based on the secondary data.

[0049] Furthermore, GHGX1-D1B indicates the GHG emission amount calculated based on the primary data for part B. Similarly, GHGX1-D2B indicates the GHG emission amount calculated based on the secondary data for part B.

[0050] Also, GHGX1-D1C indicates the GHG emission amount calculated based on the primary data for part C. Similarly, GHGX1-D2C indicates the GHG emission amount calculated based on the secondary data for part C.

[0051] Furthermore, GHGX1-D1D indicates the GHG emission amount calculated based on the primary data for part D. Similarly, GHGX1-D2D indicates the GHG emission amount calculated based on the secondary data for part D.

[0052] Furthermore, GHGX1-D1E indicates the GHG emission amount calculated based on the primary data for part E. Similarly, GHGX1-D2E indicates the GHG emission amount calculated based on the secondary data for part E.

[0053] Also, GHGX1-D1F indicates the GHG emission amount calculated based on the primary data for part F. Similarly, GHGX1-D2F indicates the GHG emission amount calculated based on the secondary data for part F.

[0054] Furthermore, GHGX1-D1G indicates the GHG emission amount calculated based on the primary data for part G. Similarly, GHGX1-D2G indicates the GHG emission amount calculated based on the secondary data for part G.

[0055] Furthermore, GHGX1-D1H indicates the GHG emission amount calculated based on the primary data for part H. Similarly, GHGX1-D2H indicates the GHG emission amount calculated based on the secondary data for part H.

[0056] As described above, in Fig. 4, the area is proportional to the amount of GHG emissions. Therefore, in Fig. 4(C), it can be seen that part D has the largest amount of GHG emissions. However, it can be seen that part B has the largest amount of GHG emissions calculated based on the primary data.

[0057] Next, the operation of the policy proposal system of the embodiment will be described with reference to Fig. 4. [1] First Embodiment Fig. 5 is a sequence chart of the policy proposal system of the first embodiment. When an instruction to create a proposal (proposal request) for reducing GHG emissions for a product composed of multiple parts is issued from the user terminal 11 (step S11), the GHG emission reduction proposal system 12 accesses the database system 13 and transmits part information corresponding to the product and corresponding CFP data acquisition source information to the GHG emission reduction proposal system (step S12).

[0058] As a result, the system controller 12A of the GHG emission reduction proposal system 12 registers a parts list of the product based on the parts information, and performs a CFP data collection process to collect CFP data based on the CFP data acquisition source information (step S13). Subsequently, the GHG emission reduction proposal system 12 performs a proposal generation process (step S14).

[0059] 6 is a flowchart of the proposal generation process. First, the system controller 12A of the GHG emission reduction proposal system 12 selects N parts with high GHG emissions from among the parts of the product based on the collected CFP data (step S21).

[0060] In this case, the CFP data corresponding to one part is made up of a combination of primary data and secondary data (however, it may be made up of only one of them) as explained in Fig. 1. Next, the system controller sets the value of the processing number counter X to an initial value = 1 (step S22).

[0061] Next, the system controller 12A of the GHG emission reduction proposal system 12 determines whether the proportion of primary data included in the CFP data for the Xth part is equal to or greater than a predetermined threshold value (for example, 50%) (step S23).

[0062] If the result of the judgment in step S23 is that the proportion of primary data included in the CFP data for the Xth part is equal to or greater than a predetermined threshold value (e.g., 50%), the system controller of the GHG emission reduction proposal system 12 generates a proposal (first reduction proposal information) for implementing reduction efforts to reduce GHG emissions during the manufacture of the part (step S24), since the amount of GHG reduction can be effectively increased by further reducing the GHG emissions indicated by the primary data, and then proceeds to step S26.

[0063] If the result of the judgment in step S23 is that the proportion of primary data contained in the CFP data for the Xth part is less than a predetermined threshold (e.g., 50%), in order to further ensure future reductions in GHG emissions, the system controller 12A of the GHG emission reduction proposal system 12 generates an implementation proposal (second reduction proposal information) for an initiative to increase the proportion of primary data in the CFP data corresponding to the part (step S25), and adds 1 to the value of the processing number counter X (step S26).

[0064] Next, the system controller 12A of the GHG emission reduction proposal system 12 determines whether the value of the processed number counter X has exceeded the selection number N (step S27).

[0065] In the judgment of step S27, if the value of the processing number counter X is still less than or equal to the selection number N (step S23; Yes), the system controller of the GHG emission reduction proposal system 12 proceeds to step S23 and continues the above-described processing for the next part.

[0066] In the determination at step S27, if the value of the processing number counter X exceeds the selection number N (step S27; Yes), the processing of all the selected N parts has been completed, and the proposal generation process is terminated.

[0067] After completing the proposal generation process, the GHG emission reduction proposal system 12 transmits the generated reduction proposal information (first reduction proposal information and second reduction proposal information) to the user terminal 11 and ends the process (step S15).

[0068] Here, the reduction proposal data as the reduction proposal information will be described. As described above, the reduction proposal information includes first reduction proposal information and second reduction proposal information. First, the first reduction proposal data as the first reduction proposal information will be described.

[0069] 7 is an explanatory diagram of the data format of the first reduction proposal data DD1. The first reduction proposal data DD1 includes reduction proposal specification information data 21, reduction proposal target product specification information data 22, and reduction proposal content information data 23.

[0070] The reduction proposal specification information data 21 includes reduction proposal ID data 21A and date and time data 21B. The reduction proposal target product specification information data 22 includes company ID data 22A and product ID data 22B.

[0071] The reduction proposal content information data 23 includes pre-reduction CFP data 23A, post-reduction CFP data 23B, and reduction rate data 23C.

[0072] The reduction proposal identification information data 21 stores information for identifying a reduction proposal corresponding to the reduction proposal information and information on the date and time when the reduction proposal was made. The reduction proposal ID data 21A stores ID information uniquely assigned to a reduction proposal for identifying a reduction proposal corresponding to the reduction proposal information. The date and time data 21B stores the date (e.g., 2024 / 5 / 13) and time (e.g., 13:45:50) when the reduction proposal was made.

[0073] The reduction proposal target product identification information data 22 stores information for identifying products that are the subject of GHG reduction proposals. The company ID data 22A stores ID information uniquely assigned to a company for identifying the company that manufactures the products that are the subject of GHG reduction proposals. The product ID data 22B stores ID information uniquely assigned to a product for identifying the products that are the subject of GHG reduction proposals.

[0074] Information for specifying the requested GHG reduction is stored in the reduction proposal content information data 23. Pre-reduction CFP data 23A stores the GHG emission amount (kg) before reduction.

[0075] The post-reduction CFP data 23B stores the post-reduction GHG emission amount (kg) presented as a target value in the GHG reduction proposal. The reduction rate data 23C stores the GHG reduction rate when the pre-reduction GHG emission amount (kg) is set to the post-reduction GHG emission amount (kg).

[0076] Therefore, a user (supplier, etc.) who receives the first reduction proposal data via the user terminal 11 can reduce GHG emissions by making improvements to the corresponding products so that the GHG emissions reach the target value of the GHG reduction proposal.

[0077] 8 is an explanatory diagram of the data format of the second reduction proposal data DD2. The second reduction proposal data DD2 includes reduction proposal specification information data 31, reduction proposal target product specification information data 32, and primary data proportion increase proposal information data 33.

[0078] The reduction proposal specification information data 31 includes reduction proposal ID data 31A and date and time data 31B. The reduction proposal target product specification information data 32 includes company ID data 32A and product ID data 32B.

[0079] The primary data proportion increase proposal content information data 33 includes pre-increase primary data proportion data 33A, post-increase primary data proportion data 33B, and increase proportion data 33C.

[0080] The reduction proposal identification information data 31 stores information for identifying a reduction proposal corresponding to the reduction proposal information and information on the date and time when the reduction proposal was made. The reduction proposal ID data 31A stores ID information uniquely assigned to a reduction proposal for identifying a reduction proposal corresponding to the reduction proposal information. The date and time data 31B stores the date (e.g., 2024 / 7 / 13) and time (e.g., 09:18:32) when the reduction proposal was made.

[0081] The reduction proposal target product identification information data 32 stores information for identifying products that are the subject of GHG reduction proposals. The company ID data 32A stores ID information uniquely assigned to a company for identifying the company that manufactures the products that are the subject of GHG reduction proposals.

[0082] The product ID data 32B stores ID information uniquely assigned to a product for identifying the product that is the target of the GHG reduction proposal.

[0083] The primary data proportion increase proposal content information data 33 stores information for specifying the proposal content for increasing the primary data proportion. The pre-increase primary data proportion data 33A stores the proportion (%) of primary data included in the CFP data before the primary data increase.

[0084] The increased primary data ratio data 33B stores the target ratio (%) of primary data included in the CFP data after the primary data is increased.

[0085] The increase rate data 33C stores the rate (%) of primary data contained in the CFP data before the primary data increase, and the increase rate (%) of primary data contained in the CFP data when the target rate (%) of primary data contained in the CFP data after the primary data increase is set as the increase rate (%) of primary data contained in the CFP data.

[0086] Therefore, a user (supplier, etc.) who receives the second reduction proposal data via the user terminal 11 can improve the proportion of primary data included in the CFP data for the corresponding product so that it matches the target value of the proposal to increase the proportion of primary data, thereby increasing the proportion of primary data and subsequently making it possible to increase the efficiency of GHG emission reduction.

[0087] FIG. 9 is an explanatory diagram of an example of a GHG emission reduction proposal display screen displayed on the display screen of the display device of the user terminal of a user who has received the first reduction proposal data and the second reduction proposal data.

[0088] The GHG emission reduction proposal display screen 11A includes a product name display area 41, a product image display area 42, a reduction proposal display area 43, and a CFP data summary display area 44.

[0089] The product name display area 41 displays the product name of the product that is the target of the GHG emission reduction proposal ("XXXXX-XX" in the example of FIG. 9). The product image display area 42 displays an image of the product that is the target of the GHG emission reduction proposal.

[0090] The reduction proposal display area 43 is an area for displaying the reduction proposal information (corresponding to the first reduction proposal data DD1 or the second reduction proposal data DD2) transmitted to the user terminal 11 by the GHG emission reduction proposal system 12.

[0091] In the example of FIG. 9, the reduction proposal display area 43-1 displays the GHG reduction target value for part B corresponding to the first reduction proposal data DD1 and the reduction rate for the GHG reduction amount of the entire product.

[0092] The reduction proposal display area 43-2 displays a proposal that the GHG reduction amount for the entire product can be improved by increasing the proportion of the CFP data corresponding to part D in the primary data for part D corresponding to the second reduction proposal data DD2.

[0093] The CFP data summary display area 44 displays an overview diagram showing the current CFP data of the product that is the subject of the GHG emission reduction proposal, including the ratio of primary data to secondary data for the representative parts that make up the product.

[0094] Therefore, by simply looking at the GHG emission reduction proposal display screen 11A, the user can easily grasp the direction for increasing GHG reduction amounts, and can easily plan and implement measures for GHG reduction.

[0095] As explained above, according to the first embodiment, if the proportion of primary data that makes up the CFP data obtained for a certain product is greater than or equal to a predetermined value, a target value for GHG reduction is presented, and if the proportion of primary data that makes up the CFP data is less than the predetermined value, an increase target value is presented to increase the proportion of primary data that makes up the CFP data.This makes it possible to easily reduce GHG emissions immediately or in the future, and to make an effective long-term contribution to society.

[0096] [2] Second Embodiment Fig. 10 is a sequence chart of a policy proposal system according to a second embodiment. In Fig. 10, the same parts as those in the first embodiment shown in Fig. 5 are denoted by the same reference numerals.

[0097] When an instruction to create a proposal (proposal request) for reducing GHG emissions for a product consisting of multiple parts is made from the user terminal 11 (step S11), the GHG emission reduction proposal system 12 accesses the database system 13 and transmits part information corresponding to the product and information on where to obtain the corresponding CFP data to the GHG emission reduction proposal system (step S12).

[0098] As a result, the GHG emission reduction proposal system 12 registers a parts list of the product based on the parts information, and performs a CFP data collection process to collect CFP data based on the CFP data acquisition source information (step S13). Subsequently, the GHG emission reduction proposal system 12 performs a proposal generation process (step S14).

[0099] The details of the proposal generation process are the same as those in the first embodiment shown in FIG. 6, and therefore the detailed description thereof is incorporated herein.

[0100] After completing the proposal generation process (step S14), the GHG emission reduction proposal system 12 sends the generated reduction proposal information (first reduction proposal information and second reduction proposal information) to the user terminal 11, and adds part information to the generated reduction proposal information and sends it to the CFP simulation system 14, thereby completing the process (step S15A).

[0101] As a result, the CFP simulation system 14 performs simulation UI (User Interface) display control to display a simulation UI screen on the display screen of the user terminal 11 (step S16).

[0102] As a result, the simulation UI screen is displayed on the display screen of the user terminal 11 (step S17).

[0103] That is, the CFP simulation system 14 functions as at least one processor and outputs a simulation UI that allows the target parts to be targeted by measures and target values ​​for the target parts to be set as a display screen or UI screen of the user terminal 11 that functions as a presentation unit.

[0104] 11 is an explanatory diagram of a display example of a simulation UI screen 11B. The simulation UI screen 11B includes a CFP data summary display / operation area 51, a target value setting area 52, and a simulation result display area 53.

[0105] The CFP data overview display / operation area 51 displays an overview of the CFP data (primary data + secondary data) for each part, and highlights the display area corresponding to the part for which a reduction target corresponding to the reduction proposal information can be set as the area to be operated.

[0106] In the example of Figure 11, the display operation area ARC corresponding to the area GHGX1-D1C showing the GHG emission amount calculated based on the primary data for part C and the area GHGX1-D2C showing the GHG emission amount calculated based on the secondary data for part C are highlighted.

[0107] The target value setting area 52 is an area in which a target value for the GHG reduction amount is set for each part.

[0108] Then, by clicking on the highlighted display operation area ARC, information about the corresponding part (part name, quantity, and current CFP: in the example of FIG. 11, "Part C," "4," and "750 kg") is displayed, and input of the target CFP value is prompted, and the target value is set and input in the user terminal 11 (step S18). Note that FIG. 11 shows the state after input, with "350 kg" already input as the CFP target value.

[0109] As a result, the input target value is notified to the CFP simulation system 14 as target value information (step S19).

[0110] As a result, the CFP simulation system 14 performs a CFP simulation based on the target values, and performs simulation UI display control to display the CFP simulation results on the simulation UI screen 11B (step S20).

[0111] Then, the CFP before and after the simulation of the entire product is displayed together with the target value in the simulation result display area 53 of the simulation UI screen 11B (step S21).

[0112] That is, the CFP simulation system 14 functions as at least one processor, receives input from the user terminal 11 as input from the user, and outputs simulation results based on target values ​​corresponding to the target value information to the display screen of the user terminal 11 as a presentation unit.

[0113] As explained above, according to the second embodiment, in addition to the effects of the first embodiment, the user is prompted to input a target value based on the reduction proposal information (particularly the first reduction proposal information), and the results are simulated and presented according to the input target value. This supports the user (supplier) in reducing GHG emissions and encourages them to implement GHG reduction, making it possible to easily increase the effectiveness of GHG reduction.

[0114] Therefore, it becomes even easier for users to contribute to society.

[0115] [3] Third Embodiment The third embodiment differs from the first embodiment in that it more efficiently reduces GHG emissions by also requesting improvements from external systems, i.e., external systems. Figure 12 is a sequence chart of the policy proposal system of the third embodiment. In Figure 12, the same parts as in Figure 5 are assigned the same reference numerals. When an instruction to create a proposal (proposal request) for reducing GHG emissions for a product composed of multiple parts is issued from the user terminal 11 (step S11), the GHG emission reduction proposal system 12 accesses the database system 13 and transmits part information corresponding to the product and corresponding CFP data acquisition source information to the GHG emission reduction proposal system (step S12).

[0116] As a result, the system controller 12A of the GHG emission reduction proposal system 12 registers a parts list for the product based on the parts information, and requests the other company's CFP providing system 18 to transmit CFP data based on the CFP data source information in order to perform a CFP data collection process for collecting CFP data based on the CFP data source information (step S13A). The other company's CFP providing system 18 then transmits the requested CFP data to the GHG emission reduction proposal system 12 (step S31). Next, the GHG emission reduction proposal system 12 performs a process similar to that shown in FIG. 6 to perform a proposal generation process (step S14A). In this proposal generation process, not only is a proposal generated for the user terminal 11, but an improvement request for issuing an improvement request to the other company's user terminal 17 is also generated as improvement request information.

[0117] After completing the proposal generation process, the system controller 12A of the GHG emission reduction proposal system 12 transmits the generated reduction proposal information (first reduction proposal information and second reduction proposal information) to the user terminal 11 (step S15). Similarly, the GHG emission reduction proposal system 12 transmits the generated improvement request information (first improvement request information and second improvement request information) to the other company's CFP provision system 18 and the other company's user terminal 17 (step S32). That is, the processor as the system controller 12A generates and transmits the improvement request information, which describes the target parts that are the subject of the measures and the target values ​​for the target parts, as a command to the other company's CFP provision system 18, which is an external CFP provision system.

[0118] Here, the improvement request data as the improvement request information will be described. As described above, the improvement request information, which describes the target parts to be targeted by the measures and the target values ​​for the target parts, includes first improvement request information and second improvement request information, and is generated and transmitted as a command to the external CFP providing system 18. First, the first improvement request data as the first improvement request information will be described. This first improvement request data is data for requesting a CFP reduction.

The date and time data 21B stores the date (e.g., 2022 / 3 / 1) and time (e.g., 09:32:20) when the improvement request was made.

[0123] The improvement-requested product identification information data 62 stores information for identifying products that are the subject of a GHG reduction improvement request. The company ID data 62A stores ID information uniquely assigned to a company for identifying a company that manufactures a product that is the subject of a GHG reduction improvement request. The product ID data 62B stores ID information uniquely assigned to a product for identifying a product that is the subject of a GHG improvement request proposal.

[0124] The improvement request content information data 63 stores information for specifying the content of the improvement request for GHG reduction. The pre-reduction CFP data 63A stores the GHG emission amount (kg) before reduction.

[0125] The post-reduction CFP data 63B stores the post-reduction GHG emission amount (kg) presented as the target value of the GHG reduction proposal. The reduction rate data 63C stores the GHG reduction rate when the pre-reduction GHG emission amount (kg) is set to the post-reduction GHG emission amount (kg).

[0126] Therefore, the GHG reduction officer of the other company who receives the first improvement request data DI1 via the other company's user terminal 17 will consider whether it is possible to improve the corresponding product so that the GHG emissions will reach the target value of the GHG reduction improvement request, and if it is determined that improvement is possible, the improvement will be made, thereby enabling a reduction in GHG emissions in the future.

[0131] The improvement-requested product identification information data 72 stores information for identifying the product that is the subject of the improvement request. The company ID data 72A stores ID information uniquely assigned to a company for identifying the company that manufactures the product that is the subject of the improvement request.

[0132] The product ID data 72B stores ID information uniquely assigned to a product for identifying the product that is the subject of the improvement request.

[0133] The primary data ratio improvement request content information data 73 stores information for specifying the content of the proposal to increase the primary data ratio. The current primary data ratio data 73A stores the ratio (%) of primary data contained in the CFP data at the current time.

[0134] The request response time primary data ratio data 73B stores the target ratio (%) of primary data included in the CFP data after the improvement has been made in accordance with the improvement request.

[0135] The increase rate data 73C stores the rate (%) of primary data contained in the CFP data before the primary data increase, and the increase rate (%) of primary data contained in the CFP data after the primary data increase when the target rate (%) of primary data contained in the CFP data after the primary data increase is set as the increase rate.

[0136] Therefore, other company users who receive the second improvement request data via user terminal 11 can improve the proportion of primary data contained in the CFP data for the corresponding product so that it matches the target value of the primary data proportion improvement request, thereby increasing the proportion of primary data and making it possible to increase the efficiency of GHG emission reduction in the future.
