[Technical Field]

[0001] The present disclosure relates to an environmental impact assessment system, an environmental impact assessment method, and an environmental impact assessment program. [Background technology]

[0002] In recent years, product manufacturers have been taking steps to address environmental issues such as carbon dioxide emissions and global warming, disclosing environmental impact assessment values, such as greenhouse gas emissions for each organization and product. Users are also becoming interested in environmental initiatives and may consider these environmental impact assessment values ​​when purchasing products.

[0003] Companies are required to properly understand the environmental impact of their product manufacturing and other activities and to present this information to users.

[0004] For example, Patent Document 1 discloses an emissions simulation system that utilizes information indicating the amount of carbon dioxide emissions in the manufacturing process of each component that constitutes a target product. Specifically, the emissions simulation system utilizes the amount of carbon dioxide emissions in the manufacturing process of each component that are published by the supplier or manufacturer of each component, thereby improving the accuracy of estimates of carbon dioxide emissions at the time of product design.

[0005] [Patent Document 1] Japanese Patent Application Publication No. 2024-053672 Summary of the Invention [Problem to be solved by the invention]

[0006] However, the emissions simulation system in Patent Document 1 does not take into account the carbon dioxide emissions associated with individual products desired by users, and may not be able to properly calculate the carbon dioxide emissions based on the individual circumstances of the product.

[0007] Therefore, the present disclosure aims to provide an environmental impact assessment system, an environmental impact assessment method, and an environmental impact assessment program that can appropriately assess the impact on the environment associated with products desired by users, based on the circumstances of each product. [Means for solving the problem]

[0015] Preferred embodiments of the present disclosure will be specifically described below with reference to the accompanying drawings. Note that the embodiment described below is merely a specific example for implementing the present disclosure and is not intended to limit the scope of the present disclosure. Furthermore, to facilitate understanding of the description, the same components in each drawing will be denoted by the same reference numerals whenever possible, and duplicate descriptions may be omitted.

[0016] First Embodiment [Product life cycle] Figure 1 is a diagram for explaining the environmental impact of a product during its life cycle. As shown in Figure 1, the environmental impact of a product can be expressed using the carbon dioxide emissions from materials S10, manufacturing S20, transportation S30, use S40, and disposal S50. The carbon dioxide emissions can be calculated based on the amount of activity and the basic unit, and will be explained in detail below.

[0017] Material S10 is the material used in the product. For example, different materials may be used for each product or each product part, or the weight of material used may vary depending on the size of the same product or product part. The environmental impact of product material S10 can be expressed, for example, as carbon dioxide emissions using the following equation (1). The weight used is the weight of material input minus the remaining weight, including process losses. For example, if material is cut from a single piece of fabric and used in a product, the weight used may be the entire sheet of fabric, including the loss. Furthermore, if a product is manufactured using a 3D printer, the amount of resin ink used may be the weight used. Carbon dioxide emissions (material) = Σ(weight used [g] x unit of production per part [gCO 2e / g]) …(Number 1)

[0018] Manufacturing S20 is a process of manufacturing a product, and includes, for example, manufacturing a product in a factory. As an impact on the environment related to manufacturing S20 of the product, for example, carbon dioxide emissions during factory operation can be expressed using the following (Equation 2) based on the processing time for processing the product, rated power, fuel consumption, thermal efficiency, etc. Carbon dioxide emissions (manufacturing) = Σ(processing time [h] × rated power [kW] × basic unit [gCO 2e / kWh]) + Σ(Fuel consumption [g] × Thermal efficiency [MJ / g] × Unit consumption [gCO 2e / MJ]) …(Number 2) Alternatively, the power consumption amount based on past factory performance (for example, annual power consumption amount) divided by the actual number of products produced (excluding defective products) may be used as an estimated value.

[0019] Transportation S30 is a process of transporting products, and includes, for example, delivering manufactured products to a predetermined destination (for example, a purchaser). Transportation also includes transportation of raw materials to a manufacturing plant, transportation of waste from the manufacturing plant to a waste disposal site, and transportation when the purchaser returns the product. As an impact on the environment related to product transportation S30, for example, in truck transportation, rail transportation, marine transportation, air transportation, etc., the carbon dioxide emissions can be expressed using the following (Equation 3) based on the transported weight and transport distance, etc. Carbon dioxide emissions (transportation) = Σ(transport weight [g] × transport distance [km] × basic unit [gCO 2e / g·km]) …(Equation 3)

[0020] Use S40 is a process in which a user uses a product, and includes, for example, the user cleaning, repairing, and storing the product. As an impact on the environment related to product use S40, for example, when washing a product using a washing machine, the carbon dioxide emissions can be expressed using the following (Equation 4) based on the usage time of the washing machine, the rated power, and the amount of water, detergent, etc. used. Carbon dioxide emissions (usage) = Σ(usage time [h] × rated power [kW] × intensity [gCO 2e / kWh]) + Σ(material usage [g] × basic unit [gCO 2e / g]) …(Number 4) In addition, this item may include, to the extent possible, the consumption and disposal of maintenance agents (oil, etc.) for repairs and storage, as well as the power consumption when using electrical appliances other than washing machines, such as dryers.

[0021] Disposal S50 is a process in which the user disposes of the product, and includes, for example, the user disposing of the product. As an impact on the environment related to product disposal S50, for example, in the case of incineration at the factory, landfilling, recycling, etc., carbon dioxide emissions can be expressed using the following (Equation 5) based on the waste weight, etc. The treatment of waste generated at the manufacturing factory is also calculated in this section. The basic unit mainly uses those specified by disposal method. Carbon dioxide emissions (disposal) = Σ (weight of waste [g] × basic unit [gCO 2e / g]) …(Number 5)

[0022] In this way, products have an impact on the environment through the materials used in their manufacture and their life cycle from manufacture to disposal, and this impact can be evaluated using carbon dioxide emissions, etc.

[0023] Furthermore, carbon dioxide emissions are not calculated separately for the aforementioned stages of material (S10), production (S20), transportation (S30), use (S40), and disposal (S50) based on the factors that affect carbon dioxide emissions. The calculation may include other factors that affect carbon dioxide emissions, or the calculation may not be clearly separated according to the aforementioned stages. Strictly speaking, since the unit of production (S10) includes the transportation and waste losses of raw materials used to make the raw materials for product parts, the carbon dioxide emissions calculation does not necessarily include the carbon dioxide emissions of the materials themselves, but also includes the transportation of raw materials, weight losses during material production using raw materials, and energy consumption during material production. Therefore, carbon dioxide emissions during production (S20) include those derived from the assembly of product parts and products, while carbon dioxide emissions during transportation (S30) are calculated from the energy consumption associated with the company's own product manufacturing. The carbon dioxide emissions for S40 use will vary depending on the maintenance method actually used by the user, and will include not only the emissions from the wastewater treatment of water used for washing, which we assume, but also the power consumption of home appliances (washing machines, dryers, etc.) and the consumption of materials such as deodorants and moisturizing oils.

[0024] [Configuration of the Environmental Impact Assessment System] 2 is a system overview diagram showing an environmental impact assessment system 10 according to the first embodiment of the present disclosure. As shown in FIG. 2, the environmental impact assessment system 10 includes a server device 100 and a terminal 11. The server device 100 includes a storage unit 110, a prediction information generation unit 120, an environmental index calculation unit 130, and an output unit 140. The server device 100 may also acquire user information U10 from the terminal 11 and output the environmental index to the terminal 11.

[0025] The server device 100 may acquire, from an electronic commerce (EC) site, information that a user inputs when ordering a product, as user information U10.

[0026] In this embodiment, footwear such as shoes is used as an example of a product for which the environmental impact is assessed in the environmental impact assessment system 10, but the product is not limited to this. For example, the product for which the environmental impact is assessed may also be a footwear part (insole, etc.), clothing (clothes, socks, hats, etc.), accessories, or other products that are worn directly or indirectly around a part of the body (rings, glasses, goggles, earrings, headphones, earphones, etc.).

[0027] The terminal 11 may be a user's terminal or a terminal installed in a store, and includes, for example, a personal computer, a tablet, a smartphone, and the like.

[0028] Users and store clerks may use terminal 11 to input user information U10 about the user, update and confirm the user information U10, and even to input and confirm information for the user to order products.

[0029] The user, a store clerk, or the like may check or update information about the product when the user orders the product and after the user purchases the product.

[0030] 3 is a diagram showing a specific example of the user information U10. As shown in FIG. 3, the user information U10 includes physical information, product information, delivery information, maintenance information, usage information, and disposal information.

[0031] The physical information includes information about the user's height, weight, foot size, and footprint. For example, the user inputs the user's height and weight using the terminal 11. The foot size and footprint information may be acquired by measuring the user's feet using a dedicated application installed on a smartphone or a dedicated measuring device installed in a store. The footprint information may be scan data of the user's feet or 3D model data generated based on the scan data.

[0032] More specifically, the physical information may be any information about the body that affects changes in the product due to use. For example, it may include information about the user's height, weight, sex, the size or shape of the part of the body that corresponds to the product, and movement tendencies. Information about movement tendencies may include, for example, information about walking or running tendencies (e.g., pace, stride width, pronation angle and type, ground contact type, pressure on the foot, etc.). If the product is a shoe or insole, the size or shape of the part of the body that corresponds to the product may include, for example, foot size, arch size, width or height, and foot shape.

[0033] The information about the user, including the physical information, may be acquired from a device used by the user, such as the user's smartphone. The information may also be acquired from a system that executes an application used by the user. Here, the application used by the user may be, for example, an application that manages product usage records, particularly, a running record application. The information about the user, including the physical information, may also be acquired from the terminal used by the user or the system that executes the application used by the user, via a terminal installed in a store.

[0034] Product information includes information regarding product type, product shape, color, etc. For example, a user inputs the product type (model), product shape, and color of a desired product using terminal 11. Here, the desired product may be a product that the user orders (including products that the user has actually ordered and products that the user is considering ordering). Furthermore, product shape and color may be set in detail for each product and product part. Furthermore, product information is not limited to information that is based on the assumption of ordering, and may also include preference information including the user's preferred product type (model), product shape, color, etc.

[0035] The product desired by the user may be a custom-made product, a product manufactured in small lots, or a product manufactured in large quantities and sold commercially.

[0036] The delivery information includes information regarding the delivery address, delivery means, delivery deadline, etc. For example, the user inputs the delivery address, delivery means, and delivery deadline using the terminal 11. The delivery address is the destination of the product ordered by the user. The delivery means includes truck transport, land transport, rail transport, marine transport, air transport, etc., and may be automatically set based on the delivery address or may be input by the user. The delivery deadline may be automatically set based on the product information and delivery address of the ordered product, or the desired delivery deadline may be input by the user.

[0037] Note that the delivery means and the delivery deadline may be related to each other. For example, the user may be configured to be able to input the delivery means and delivery deadline while taking into consideration the impact on the environment, using the terminal 11, while checking the environmental indicators described below.

[0038] The maintenance information includes information on the cleaning method, cleaning frequency, repair method, and storage method. For example, the user uses the terminal 11 to input the cleaning method, cleaning frequency, repair method, and storage method of the ordered product. Specifically, the cleaning method includes using a washing machine and hand washing, and the cleaning frequency includes once a week and once a month. Cleaning methods other than washing are also expected, such as deodorizing sprays. Repair methods for textile products include repairs by embroidery and the use of raw thread. Furthermore, for re-soling, the use of materials (tape and adhesive) and additional charges due to the power consumption caused by processing are expected. Storage methods are expected to include the use of moisture absorbents and deodorizing sprays.

[0039] The usage information includes information regarding the purpose of use, frequency of use, intensity of use, road surface conditions at the time of use (e.g., concrete, dirt, grass, tartan, etc.), mileage, running speed, and storage method. For example, the user uses the terminal 11 to input the purpose of use, frequency of use, intensity of use, road surface conditions at the time of use, mileage, running speed, and storage method of the ordered product. Specifically, the purpose of use includes commuting and running, etc., the frequency of use is the frequency of use during a specific period, the mileage is the mileage per day, per week, or per month, etc., and the running speed is the running speed at that time. The storage method includes whether the product is stored indoors or outdoors, and whether or not a shoe tree is used.

[0040] The disposal information includes information about the disposal method, etc. For example, the user may input the disposal method for the ordered product using the terminal 11, or the disposal method may be automatically set based on local government information assumed from the delivery address.

[0041] The user information U10 does not have to include all of the above-mentioned information, and is not limited to the above-mentioned information. Information about the user who orders, uses, and disposes of the product, and information about the product, may be input using the terminal 11 or automatically acquired as the user information U10.

[0042] Returning to the explanation of Fig. 2, information necessary for manufacturing footwear (products) and information necessary for evaluating the impact on the environment are stored in storage unit 110. For example, storage unit 110 may be provided in server device 100, may be configured separately from server device 100, may be configured with multiple storage units, or may be in the form of a database.

[0043] Specifically, storage unit 110 stores identification information for identifying a product, material information related to the material of the product, and manufacturing information related to the manufacturing of the product. The identification information identifies the product and may be, for example, a unique management number composed of alphanumeric characters and symbols, or a two-dimensional barcode. The identification information is linked to information related to the product that corresponds to the user who uses the product, and for example, material information and manufacturing information that are information necessary to manufacture footwear (products) are linked to the identification information.

[0044] Fig. 4 is a diagram showing an example of a database storing various pieces of information necessary for manufacturing footwear. As shown in Fig. 4, the database stores identification information D10, material information D20, and manufacturing information D30 in association with each other.

[0045] For example, the footwear desired by the user is identified based on product information (such as product type, product shape, and color) and the user's foot size and shape included in the user information U10. The footwear is then managed using identification information. The identification information may include or be linked to CAD data D11 of the footwear. If the product is footwear, the identification information may include identification information for both the left foot and the right foot.

[0046] Specifically, among products (footwear, insoles, etc.), products for the left foot (footwear, insoles, etc.) are associated with identification information for the left foot, and products for the right foot (footwear, insoles, etc.) are associated with identification information for the right foot.

[0047] Naturally, a user's right and left feet have different shapes, and are not necessarily symmetrical. For example, they may have different sizes (length and width), be suitable for different sports, or even have characteristics that correspond to different walking styles. For custom-made products (such as footwear and insoles), the left and right products are manufactured to fit the left and right feet, respectively. That is, different identification information may be assigned to each of the left and right products depending on the user.

[0048] Also, a single piece of identification information may be given to the left and right products so that they can be managed as a pair.

[0049] As described above, left and right products (footwear, insoles, etc.) are manufactured to fit the left and right feet, respectively. A single piece of identification information may be formed by combining the marks attached to the left and right products (footwear, insoles, etc.). That is, a left-foot mark attached to a product for the left foot (footwear, insoles, etc.) and a right-foot mark attached to a product for the right foot (footwear, insoles, etc.) are formed as a pair. Here, the pairing may mean that a left-foot mark and a right-foot mark are combined and the shapes of the connecting portion match to form a single piece of identification information, or that the colors, patterns, etc. of the connecting portion match to form a single piece of identification information. Furthermore, a single piece of identification information may be formed by an conceptual connection based on the content written on the left-foot mark and the right-foot mark.

[0050] The material information D20 includes the type and weight of material used for the footwear, and the manufacturing information D30 includes the manufacturing process, processing time, amount of fuel used, rated power, and thermal efficiency, as well as power consumption based on past factory performance (e.g., annual power consumption) and the number of products produced (excluding defective products). That is, the storage unit 110 stores, for each pair of footwear to be manufactured, the type and weight of material used according to product information, foot size, and foot shape as material information D20, and stores, as manufacturing information D30, the manufacturing process (including the manufacturing factory, manufacturing machines, and manufacturing method), processing time, amount of fuel used, rated power, and thermal efficiency in the manufacturing process. The weight used is the weight of material input minus the remaining amount, and includes weight loss during the process, etc.

[0051] The prediction information generation unit 120 generates prediction information based on material information D20 and manufacturing information D30, including material prediction information regarding the materials of the footwear that will be generated by manufacturing the footwear corresponding to identification information D10 and manufacturing prediction information regarding the manufacturing of the footwear.

[0052] For example, the prediction information generating unit 120 identifies the footwear desired by the user (product information (product type, product shape and color, etc.), foot size and foot shape) based on the identification information D10. The prediction information generating unit 120 generates the materials (material type and usage weight) required to manufacture the identified footwear (material prediction information), as well as the manufacturing process, processing time, fuel usage, rated power, thermal efficiency, power consumption based on past factory performance (e.g., annual power consumption, etc.) and the actual number of products produced (excluding defective products) required to manufacture the footwear (manufacturing prediction information) based on the material information D20 and the manufacturing information D30.

[0053] In this way, the prediction information generating unit 120 generates material prediction information and production prediction information that will be generated by manufacturing the footwear desired by the user.

[0054] The environmental index calculation unit 130 calculates an environmental index (first environmental index) relating to the impact on the environment associated with the footwear desired by the user based on prediction information including material prediction information and manufacturing prediction information generated by the prediction information generation unit 120.

[0055] For example, the environmental index calculation unit 130 calculates the carbon dioxide emissions (materials) using the above-mentioned (Equation 1) based on the material prediction information that will be generated by manufacturing the footwear desired by the user.

[0056] Similarly, the environmental index calculation unit 130 calculates the carbon dioxide emissions (production) using the above-mentioned (Equation 2) based on the production forecast information generated by producing the footwear desired by the user.

[0057] Then, the environmental index calculation unit 130 calculates the amount of carbon dioxide emissions emitted by manufacturing (including the use of materials) the footwear desired by the user based on the amount of carbon dioxide emissions (materials) and the amount of carbon dioxide emissions (manufacturing).

[0058] Here, the above-mentioned (Equation 1) and (Equation 2), as well as each unit of production required to calculate the carbon dioxide emissions used as an environmental index for evaluating the impact on the environment, may be stored in advance in the memory unit 110, etc.

[0059] The output unit 140 outputs the carbon dioxide emission amount (first environmental index) calculated by the environmental index calculation unit .

[0060] Fig. 5 is a diagram showing an example in which the carbon dioxide emissions emitted in the manufacture of footwear (including the use of materials) are output as an environmental index. As shown in Fig. 5, the carbon dioxide emissions O10, carbon dioxide emissions (materials) O11, and carbon dioxide emissions (manufacturing) O12 are displayed.

[0061] Carbon dioxide emissions (material) O11 indicates the amount of carbon dioxide emissions emitted in relation to the materials of the footwear desired by the user over the life cycle of the product shown in FIG.

[0062] Carbon dioxide emissions (manufacturing) O12 indicates the amount of carbon dioxide emissions emitted in connection with the manufacture of the footwear desired by the user in the life cycle of the product shown in FIG.

[0063] Carbon dioxide emissions O10 is the sum of carbon dioxide emissions (materials) O11 and carbon dioxide emissions (manufacturing) O12, and indicates how much carbon dioxide is emitted by manufacturing (including the use of materials) the footwear desired by the user.

[0064] For example, the server device 100 may output the carbon dioxide emission amount O10, the carbon dioxide emission amount (material) O11, and the carbon dioxide emission amount (production) O12 shown in FIG. 5, display them on the screen of the terminal 11, and present them to the user.

[0065] This allows users to know how much carbon dioxide will be emitted by manufacturing their desired footwear (including the use of materials) before the footwear is manufactured, which will influence users' purchasing motivations, and for example, users who are enthusiastic about environmental issues will be able to order footwear with a low carbon dioxide emission.

[0066] Additionally, one may consider the carbon dioxide emissions associated with transporting, using, and disposing of footwear during the product life cycle depicted in Figure 1 .

[0067] Fig. 6 is a diagram showing a schematic example of a database that stores various information necessary for considering the environmental impact of footwear throughout its life cycle, from its manufacture (including material use) to its disposal. As shown in Fig. 6, the database stores identification information D10, material information D20, and manufacturing information D30 described with reference to Fig. 4, as well as transportation information D40, use information D50, and disposal information D60, all of which are linked to one another.

[0068] The footwear desired by the user is managed by identification information, and the identification information may be linked to each piece of information included in the user information U10. Specifically, the identification information may be linked to delivery information (delivery address, delivery means, delivery deadline, etc.), maintenance information (cleaning method, cleaning frequency, repair method, and storage method), and disposal information (disposal method), etc., of the footwear desired by the user, which are included in the user information U10.

[0069] The transportation information D40 includes the transportation means, transportation weight, and transportation distance; the usage information D50 includes the cleaning method, usage time, rated power, and material usage; and the disposal information D60 includes the disposal means and disposal weight. That is, the storage unit 110 stores, as transportation information D40, the transportation means, transportation weight, and transportation distance corresponding to the delivery information (delivery address, delivery means, delivery deadline, etc.) for each pair of footwear to be delivered. The storage unit 110 also stores, as usage information D50, the cleaning method, usage time, rated power, material usage, amount of repair materials (thread, tape, adhesive, etc.) used, amount of stored products (moisture absorbent, deodorizing spray, etc.) used, etc. corresponding to the maintenance information (cleaning method, cleaning frequency, repair method, and storage method). The storage unit 110 also stores, as disposal information D60, the disposal means and disposal weight corresponding to the disposal information (disposal method) for each pair of footwear to be discarded.

[0070] The prediction information generation unit 120 generates transportation prediction information regarding the transportation of footwear corresponding to the identification information D10, which is generated by delivering the footwear, based on the transportation information D40. The prediction information generation unit 120 generates usage prediction information regarding the use of footwear, which is generated by maintaining the footwear corresponding to the identification information D10, based on the usage information D50. The prediction information generation unit 120 generates disposal prediction information regarding the disposal of footwear, which is generated by discarding the footwear corresponding to the identification information D10, based on the disposal information D60.

[0071] For example, the prediction information generation unit 120 generates, based on the identification information D10 and delivery information included in the user information U10 linked to the identification information D10, the transportation means, transportation weight, and transportation distance required to transport the footwear desired by the user (transportation prediction information) based on the transportation information D40. The prediction information generation unit 120 generates, based on the identification information D10 and maintenance information included in the user information U10 linked to the identification information D10, the cleaning method, usage time, rated power, water usage, amount of repair materials (thread, tape, adhesive, etc.) used, amount of stored products (moisture absorbent, deodorizing spray, etc.) used, etc. (usage prediction information) required to maintain the footwear desired by the user based on the usage information D50. The prediction information generation unit 120 generates, based on the identification information D10 and disposal information included in the user information U10 linked to the identification information D10, the disposal means and disposal weight required to dispose of the footwear desired by the user (disposal prediction information) based on the disposal information D60.

[0072] In this way, the prediction information generation unit 120 generates prediction information that includes, in addition to material prediction information and manufacturing prediction information, at least one of transportation prediction information, usage prediction information, and disposal prediction information that arise from the transportation, maintenance, and disposal of the footwear desired by the user.

[0073] The environmental index calculation unit 130 calculates an environmental index (first environmental index) relating to the impact on the environment associated with the footwear desired by the user based on the prediction information generated by the prediction information generation unit 120, which includes at least one of transportation prediction information, usage prediction information, and disposal prediction information in addition to material prediction information and production prediction information.

[0074] For example, the environmental index calculation unit 130 calculates the carbon dioxide emissions (transportation) using the above-mentioned (Equation 3) based on the transportation prediction information generated by transporting the footwear desired by the user.

[0075] Similarly, the environmental index calculation unit 130 calculates the carbon dioxide emission amount (use) using the above-mentioned (Equation 4) based on the usage prediction information generated by maintaining the footwear desired by the user.

[0076] Similarly, the environmental index calculation unit 130 calculates the carbon dioxide emission amount (disposal) using the above-mentioned (Equation 5) based on the discard prediction information that will be generated when the user discards the footwear that he or she desires.

[0077] The environmental index calculation unit 130 then calculates the amount of carbon dioxide emissions to be emitted over the life cycle of the footwear desired by the user based on prediction information including at least one of carbon dioxide emissions (transportation), carbon dioxide emissions (use), and carbon dioxide emissions (disposal) in addition to carbon dioxide emissions (materials) and carbon dioxide emissions (manufacturing).

[0078] Here, the above-mentioned (Equations 3) to (Equation 5) and each unit of consumption necessary for calculating the carbon dioxide emissions used as an environmental index for evaluating the impact on the environment may be stored in advance in the storage unit 110 or the like.

[0079] The output unit 140 outputs the carbon dioxide emission amount (first environmental index) calculated by the environmental index calculation unit .

[0080] Fig. 7 is a diagram showing an example of the carbon dioxide emissions emitted throughout the life cycle of footwear, from its manufacture (including material use) to its disposal, output as an environmental indicator. As shown in Fig. 7, in addition to the carbon dioxide emissions O10, carbon dioxide emissions (materials) O11, and carbon dioxide emissions (manufacturing) O12 explained using Fig. 5, carbon dioxide emissions (transport) O13, carbon dioxide emissions (use) O14, and carbon dioxide emissions (disposal) O15 are also displayed.

[0081] Carbon dioxide emissions (transportation) O13 indicates the amount of carbon dioxide emissions emitted in relation to the transportation of the footwear desired by the user in the life cycle of the product shown in FIG.

[0082] Carbon dioxide emissions (use) O14 indicates, for the footwear desired by the user, the amount of carbon dioxide emissions emitted in connection with the use of the footwear in the product life cycle shown in FIG.

[0083] Carbon dioxide emissions (disposal) O15 indicates the amount of carbon dioxide emissions emitted in relation to the disposal of the footwear desired by the user in the life cycle of the product shown in FIG.

[0084] Carbon dioxide emissions O10 is the sum of carbon dioxide emissions (materials) O11, carbon dioxide emissions (manufacturing) O12, carbon dioxide emissions (transportation) O13, carbon dioxide emissions (use) O14, and carbon dioxide emissions (disposal) O15, and indicates how much carbon dioxide will be emitted in the life cycle of the footwear desired by the user.

[0085] For example, the server device 100 may output the carbon dioxide emission amount O10, the carbon dioxide emission amount (materials) O11, the carbon dioxide emission amount (production) O12, the carbon dioxide emission amount (transportation) O13, the carbon dioxide emission amount (use) O14, and the carbon dioxide emission amount (disposal) O15 shown in FIG. 7, and display them on the screen of the terminal 11 to present them to the user.

[0086] This allows users to understand, before the footwear they desire is manufactured, how much carbon dioxide will be emitted from the time the footwear is manufactured (including the use of materials), through transportation, use (maintenance), and disposal. This influences users' purchasing motivations, and for example, environmentally conscious users can order footwear with a low carbon dioxide emission. Furthermore, users can become conscious of reducing carbon dioxide emissions by considering delivery means and delivery deadlines, cleaning methods, cleaning frequency, repair methods, storage methods, and disposal methods.

[0087] [Environmental Impact Assessment Method] Next, the environmental impact assessment method for evaluating the environmental impact of footwear (products) will be specifically explained in detail.

[0088] 8 is a flowchart showing the processing flow of an environmental impact assessment method M100 executed by the environmental impact assessment system 10 according to the first embodiment of the present disclosure. As shown in FIG. 8, the environmental impact assessment method M100 includes steps S110 to S130, and each step is executed by, for example, a processor included in the server device 100.

[0089] In step S110, the prediction information generating unit 120 generates prediction information based on the user information and each piece of information in the database. Specifically, the prediction information generating unit 120 generates prediction information including material prediction information and production prediction information corresponding to the footwear desired by the user, and at least one of transportation prediction information, use prediction information, and disposal prediction information, based on the identification information shown in Figures 4 and 6 stored in the storage unit 110 and each piece of information linked to the identification information.

[0090] In step S120, the environmental index calculation unit 130 calculates the environmental index (amount of carbon dioxide emission) based on the prediction information generated in step S110. Specifically, the environmental index calculation unit 130 calculates the amount of carbon dioxide emission (first environmental index) using the above-mentioned (Equation 1) to (Equation 5) based on the prediction information generated in step S110.

[0091] In step S130, the output unit 140 outputs the environmental index (amount of carbon dioxide emission). Specifically, the output unit 140 outputs the amount of carbon dioxide emission (first environmental index) calculated in step S120. The output unit 140 may display the amount of carbon dioxide emission (first environmental index) on the screen of the terminal 11 to present it to the user, as shown in Figs. 5 and 7.

[0092] [Effects of the first embodiment] According to the environmental impact assessment system 10 and environmental impact assessment method M100 of the first embodiment of the present disclosure, the storage unit 110 stores identification information D10, material information D20, and manufacturing information D30. The prediction information generation unit 120 generates material prediction information and manufacturing prediction information for footwear (products) corresponding to the identification information D10, which will be generated by manufacturing the footwear, based on the material information D20 and the manufacturing information D30. The environmental index calculation unit 130 then calculates a carbon dioxide emission amount (first environmental index) based on the material prediction information and the manufacturing prediction information, and the output unit 140 outputs the carbon dioxide emission amount (first environmental index). This allows the carbon dioxide emission amount emitted in connection with the footwear (products) desired by the user to be appropriately evaluated according to the circumstances of each of the footwear.

[0093] Conventionally, carbon dioxide emissions related to a product have been calculated as a representative example, such as the average size of each product. In contrast, the environmental impact assessment system 10 and environmental impact assessment method M100 according to the first embodiment of the present disclosure can appropriately calculate carbon dioxide emissions according to the individual circumstances (product type, product shape, color, size, etc.) of the footwear (product) desired by the user, as described above.

[0094] In particular, since footwear consists of multiple parts and comes in a wide range of sizes, it is effective to calculate carbon dioxide emissions accurately according to individual circumstances, rather than simply calculating them as a representative example. This is even more effective for footwear (products) that are made to order, with customization of the appearance, etc.

[0095] Furthermore, the storage unit 110 further stores transportation information D40, use information D50, and disposal information D60, and the prediction information generation unit 120 generates transportation prediction information for the footwear corresponding to the identification information D10, which is generated by transporting the footwear, use prediction information for the footwear, which is generated by using the footwear, and disposal prediction information for the footwear, which is generated by discarding the footwear, based on the transportation information D40, the use information D50, and the disposal information D60. Then, the environmental index calculation unit 130 calculates a carbon dioxide emission amount (first environmental index) based on the transportation prediction information, use prediction information, and disposal prediction information, and the output unit 140 outputs the carbon dioxide emission amount (first environmental index). This makes it possible to appropriately evaluate the carbon dioxide emission amount related to the footwear desired by the user, from its manufacture (including material use) to its transportation, use (maintenance), and disposal, depending on the circumstances of each footwear.

[0096] Second Embodiment Next, in a second embodiment of the present disclosure, in addition to the environmental impact assessment system 10 described in the first embodiment, an environmental impact assessment system that calculates an environmental index using performance information from factories that manufacture footwear (products) will be described.

[0097] [Configuration of the Environmental Impact Assessment System] Fig. 9 is a system schematic diagram showing an environmental impact assessment system 20 according to a second embodiment of the present disclosure. Note that in Fig. 9, the same components as those in the environmental impact assessment system 10 according to the first embodiment of the present disclosure shown in Fig. 2 are denoted by the same reference numerals, and detailed description thereof will be omitted. In this embodiment, the components different from the first embodiment of the present disclosure will mainly be described.

[0098] 9, the environmental impact assessment system 20 includes a server device 200 and a terminal 11. The server device 200 includes a storage unit 110, a prediction information generation unit 120, a performance information acquisition unit 210, an environmental index calculation unit 230, and an output unit 240. The server device 200 may also acquire user information U10 from the terminal 11, acquire material performance information A10 and production performance information A20 from a factory 21 that manufactures footwear (products), and output the environmental indexes to the terminal 11.

[0099] The performance information acquisition unit 210 acquires material performance information A10 relating to the materials of the manufactured footwear (actual product) when the footwear (product) desired by the user is actually manufactured at the factory 21, and manufacturing performance information A20 relating to the manufacturing of the manufactured footwear (actual product).

[0100] For example, the performance information acquisition unit 210 may acquire weight data of the manufactured footwear (performance product) by measuring the weight of the footwear, or may acquire the weight of each material used by measuring the remaining amount of each material (tank weight in a 3D printer) before and after manufacturing the footwear (material performance information A10).

[0101] The performance information acquisition unit 210 may acquire the processing time and power consumption used in manufacturing the footwear by actually measuring (acquiring information using various sensors (including weight, time, product power consumption, and time measurement using foot stamps such as photography)), or, if fuel has actually been consumed, may acquire the amount of fuel used and thermal efficiency by measuring the remaining amount before and after manufacturing the footwear (manufacturing performance information A20).

[0102] For example, if factory 21 operates using renewable energy, performance information acquisition unit 210 may acquire the amount of power consumption based on data on the amount of power generated from solar panels during the period in which the footwear is manufactured.

[0103] The environmental index calculation unit 230 calculates an environmental index (second environmental index) relating to the impact on the environment related to the manufactured footwear (actual product) based on performance information including material performance information A10 and manufacturing performance information A20 acquired by the performance information acquisition unit 210.

[0104] For example, the environmental index calculation unit 230 calculates the carbon dioxide emissions (materials) using the above-mentioned (Equation 1) based on the material performance information A10 generated by the actual production of the footwear (product) desired by the user at the factory 21.

[0105] Similarly, the environmental index calculation unit 230 calculates the carbon dioxide emissions (manufacturing) using the above-mentioned (Equation 2) based on the manufacturing performance information A20 generated by the actual manufacturing of the footwear (product) desired by the user at the factory 21.

[0106] Then, the environmental index calculation unit 230 calculates the amount of carbon dioxide emissions emitted as a result of actually manufacturing (including the use of materials) the footwear desired by the user based on the amount of carbon dioxide emissions (materials) and the amount of carbon dioxide emissions (manufacturing).

[0107] The output unit 240 outputs the carbon dioxide emission amount (second environmental index) calculated by the environmental index calculation unit 230 together with the carbon dioxide emission amount (first environmental index) output by the output unit 140, or so as to update the carbon dioxide emission amount (first environmental index).

[0108] Fig. 10 is a diagram showing an example of outputting, as an environmental index, the carbon dioxide emissions (including material and manufacturing results) emitted throughout the life cycle of footwear, from its manufacture (including material use) to its disposal. As shown in Fig. 10, instead of the carbon dioxide emissions (material) O11 and carbon dioxide emissions (manufacturing) O12 described with reference to Figs. 5 and 7, the carbon dioxide emissions (material results) O21 and carbon dioxide emissions (manufacturing results) O22 are displayed.

[0109] 5 are predicted values ​​calculated based on the various pieces of information stored in storage unit 110 before the footwear desired by the user is manufactured. On the other hand, carbon dioxide emission (actual material amount) O21 and carbon dioxide emission (actual manufacturing amount) O22 are actual values ​​calculated based on the various pieces of information when the footwear desired by the user is actually manufactured at factory 21.

[0110] The carbon dioxide emissions O20 is the sum of carbon dioxide emissions (material results) O21, carbon dioxide emissions (manufacturing results) O22, carbon dioxide emissions (transportation) O13, carbon dioxide emissions (use) O14, and carbon dioxide emissions (disposal) O15, and indicates the amount of carbon dioxide that will be emitted over the life cycle of the footwear desired by the user, taking into account the actual values ​​at the factory 21.

[0111] For example, the server device 200 may output the carbon dioxide emission amount O20, the carbon dioxide emission amount (material results) O21, the carbon dioxide emission amount (manufacturing results) O22, the carbon dioxide emission amount (transportation) O13, the carbon dioxide emission amount (use) O14, and the carbon dioxide emission amount (disposal) O15 shown in FIG. 10, and display them on the screen of the terminal 11 to present them to the user.

[0112] This allows the user to understand how much carbon dioxide will be emitted from the time the desired footwear is manufactured (including the use of materials) until it is transported, used (maintained), and disposed of, based on the actual values ​​at factory 21 after the desired footwear is actually manufactured. As a result, the user can understand the amount of carbon dioxide emissions emitted from the actual manufacture (including the use of materials) of the desired footwear, and can then be conscious of reducing carbon dioxide emissions by selecting the delivery means and delivery deadline, cleaning method, cleaning frequency, repair method, storage method, and disposal method, etc.

[0113] In this embodiment, the output unit 240 outputs the carbon dioxide emission amount (material actual) O21 and the carbon dioxide emission amount (production actual) O22 instead of the carbon dioxide emission amount (material) O11 and the carbon dioxide emission amount (production) O12, but it may output both. For example, the user can compare the predicted value with the actual value by checking both.

[0114] Furthermore, in this embodiment, the environmental index calculation unit 230 calculates the carbon dioxide emission amount (material actual amount) and the carbon dioxide emission amount (manufacturing actual amount) based on the material actual amount information A10 and the manufacturing actual amount information A20, and the output unit 240 outputs these. For example, when the environmental index calculation unit 230 calculates either the carbon dioxide emission amount (material actual amount) or the carbon dioxide emission amount (manufacturing actual amount) based on any of the actual amount information acquired by the actual amount information acquisition unit 210, the output unit 240 may output the carbon dioxide emission amount based on the actual amount information, and may output the carbon dioxide emission amount (material) O11 or the carbon dioxide emission amount (manufacturing) O12 described using FIG. 5 on the other hand.

[0115] [Environmental Impact Assessment Method] 11 is a flowchart showing the processing flow of an environmental impact assessment method M200 executed by the environmental impact assessment system 20 according to the second embodiment of the present disclosure. As shown in FIG. 11, the environmental impact assessment method M200 includes steps S110, S120, and steps S210 to S230, and each step is executed by, for example, a processor included in the server device 200.

[0116] Steps S110 and S120 are the same as steps S110 and S120 in the environmental impact assessment method M100 described with reference to FIG.

[0117] In step S210, performance information acquisition unit 210 acquires material performance information A10 and manufacturing performance information A20. Specifically, performance information acquisition unit 210 acquires the type and weight of materials used when manufacturing footwear at factory 21, and acquires the processing time and power consumption spent when manufacturing footwear at factory 21, as well as the actual amount of fuel used and thermal efficiency.

[0118] In step S220, the environmental index calculation unit 230 calculates the environmental index (amount of carbon dioxide emission) based on the material performance information A10 and production performance information A20 acquired in step S210. Specifically, the environmental index calculation unit 230 calculates the amount of carbon dioxide emission (second environmental index) using the above-mentioned (Equation 1) and (Equation 2) based on the material performance information A10 and production performance information A20 acquired in step S210.

[0119] In step S230, the output unit 240 outputs the environmental index (amount of carbon dioxide emission). Specifically, the output unit 240 outputs the amount of carbon dioxide emission (second environmental index) calculated in step S220 together with the amount of carbon dioxide emission (first environmental index) calculated in step S120, or instead of the amount of carbon dioxide emission (first environmental index). The output unit 240 may display the amount of carbon dioxide emission (second environmental index) on the screen of the terminal 11 together with the amount of carbon dioxide emission (first environmental index) or update the amount of carbon dioxide emission (first environmental index) to present it to the user, as shown in FIG.

[0120] [Effects of the second embodiment] According to an environmental impact assessment system 20 and an environmental impact assessment method M200 according to a second embodiment of the present disclosure, in addition to the environmental impact assessment system 10 according to the first embodiment of the present disclosure, a performance information acquisition unit 210 is provided. The performance information acquisition unit 210 acquires material performance information A10 and production performance information A20 at a factory 21. An environmental index calculation unit 230 calculates the amount of carbon dioxide emissions (second environmental index) based on the material performance information A10 and the production performance information A20, and an output unit 240 outputs the amount of carbon dioxide emissions (second environmental index) together with the amount of carbon dioxide emissions (first environmental index) or by updating the amount of carbon dioxide emissions (first environmental index). This makes it possible to appropriately evaluate the amount of carbon dioxide emissions associated with footwear (products) desired by a user, depending on the circumstances of each piece of footwear, and taking into account the amount of carbon dioxide emissions resulting from the actual manufacture (including the use of materials) of the desired footwear.

[0121] <Third embodiment> Next, in a third embodiment of the present disclosure, in addition to the environmental impact assessment system 20 described in the second embodiment, an environmental impact assessment system that calculates an environmental index using performance information of users who use footwear (products) will be described.

[0122] [Configuration of the Environmental Impact Assessment System] Fig. 12 is a system schematic diagram showing an environmental impact assessment system 30 according to a third embodiment of the present disclosure. Note that in Fig. 12, the same components as those in the environmental impact assessment system 10 according to the first embodiment of the present disclosure shown in Fig. 2 and the environmental impact assessment system 20 according to the second embodiment of the present disclosure shown in Fig. 9 are denoted by the same reference numerals, and detailed descriptions thereof will be omitted. In this embodiment, the components different from those in the first and second embodiments of the present disclosure will mainly be described.

[0123] 12, the environmental impact assessment system 30 includes a server device 300 and a terminal 11. The server device 300 includes a storage unit 110, a prediction information generation unit 120, a performance information acquisition unit 310, an environmental index calculation unit 330, and an output unit 340. The server device 300 acquires user information U30 from the terminal 11. The user information U30 includes delivery performance information, maintenance performance information, usage performance information, and disposal performance information that correspond to the delivery information, maintenance information, usage information, and disposal information in the user information U10.

[0124] Figure 13 is a diagram showing a specific example of user information U30. As shown in Figure 13, user information U30 includes physical information, product information, delivery history information, maintenance history information, use history information, and disposal history information. The delivery history information, maintenance history information, use history information, and disposal history information in user information U30 shown in Figure 13 are information based on actual delivery, maintenance, use, and disposal, compared to the delivery information, maintenance information, use information, and disposal information in user information U10 shown in Figure 3.

[0125] The delivery performance information includes information on the delivery address, delivery means, delivery deadline, etc. to which the manufactured footwear (performance product) was actually delivered. For example, the delivery address, delivery means, and delivery deadline may be input by the user using terminal 11, or may be automatically set via a delivery company's system, etc. Here, the fuel consumed for delivery (electricity, diesel, gasoline, etc.) may also be set.

[0126] The maintenance record information includes information on the cleaning method, cleaning frequency, repair method, and storage method actually used to maintain manufactured footwear (actual products). For example, the cleaning method, cleaning frequency, repair method, and storage method may be input by the user using terminal 11. Here, the cleaning method may be set to washing machine or hand washing, and drying in a dryer or sun drying, etc. The cleaning frequency may be counted each time the user washes, or may be set to the number of times in a predetermined period. Cleaning methods other than washing include deodorizing sprays, etc. In the case of textile products, repair methods include embroidery and the use of raw thread. Furthermore, resoling also includes the use of materials (tape and adhesive) and additional charges derived from the power consumption due to processing. Storage methods include the use of moisture absorbents and deodorizing sprays, etc.

[0127] The usage history information includes information regarding the purpose of use, distance traveled, running speed, and storage method of the manufactured footwear (product-proven product) that was actually used. For example, the purpose of use, distance traveled, running speed, and storage method may be input by the user using terminal 11. Here, the usage history information may be extracted by using a running application installed on the user's smartphone or the like to extract the running history (distance traveled, running speed, etc.) when wearing the footwear (product-proven product).

[0128] The disposal record information includes information about the disposal method by which manufactured footwear (actual products) was actually disposed of. For example, the disposal method may be normal disposal (municipal regulations), store collection, or transfer, which may be input by the user using terminal 11.

[0129] The performance information acquisition unit 310 acquires transportation performance information A30 relating to the transportation in which footwear (products) desired by the user are actually manufactured at the factory 21 and the manufactured footwear (performance products) are delivered to a specified destination.

[0130] The transportation history information A30 includes the delivery history information in the user information U30, as well as the transportation means, transportation weight, and transportation distance obtained and calculated based on the weight of the manufactured footwear (actual product) and each piece of information stored in the memory unit 110.

[0131] The performance information acquisition unit 310 acquires usage performance information A40 relating to the use of manufactured footwear (performance products) and disposal performance information A50 relating to the disposal of the footwear (performance products).

[0132] The usage history information A40 includes the cleaning method, usage time, rated power, water usage, and material usage for repair and storage, which are acquired and / or calculated based on the maintenance history information in the user information U30, as well as the weight of the manufactured footwear (actual product) and each piece of information stored in the memory unit 110.

[0133] The disposal history information A50 includes the disposal means and disposal weight acquired and / or calculated based on the disposal history information in the user information U30, as well as the weight of the manufactured footwear (actual product) and each piece of information stored in the memory unit 110.

[0134] The environmental index calculation unit 330 calculates an environmental index (second environmental index) relating to the impact on the environment in relation to the manufactured footwear (actual product) based on performance information including at least one of transportation performance information A30, usage performance information A40, and disposal performance information A50 acquired by the performance information acquisition unit 310.

[0135] For example, the environmental index calculation unit 330 calculates the carbon dioxide emissions (transportation) using the above-mentioned (Equation 3) based on the transportation record information A30 generated by actually transporting manufactured footwear (record products).

[0136] Similarly, the environmental index calculation unit 330 calculates the carbon dioxide emissions (usage) using the above-mentioned (Equation 4) based on the usage record information A40 generated by actually maintaining the manufactured footwear (record product).

[0137] Similarly, the environmental index calculation unit 330 calculates the carbon dioxide emissions (disposal) using the above-mentioned (Equation 5) based on the disposal record information A50 generated by actually disposing of manufactured footwear (record products).

[0138] The output unit 340 outputs the carbon dioxide emission amount (second environmental index) calculated by the environmental index calculation unit 330 together with the carbon dioxide emission amount (first environmental index) output by the output unit 140, or so as to update the carbon dioxide emission amount (first environmental index).

[0139] Fig. 14 is a diagram showing an example of outputting, as an environmental indicator, the carbon dioxide emissions (including the results of materials, production, transportation, use, and disposal) emitted throughout the life cycle of footwear, from its manufacture (including the use of materials) to its disposal. As shown in Fig. 14, instead of the carbon dioxide emissions (transportation) O13, the carbon dioxide emissions (use) O14, and the carbon dioxide emissions (disposal) O15 described with reference to Figs. 7 and 10, the carbon dioxide emissions (transportation results) O33, the carbon dioxide emissions (use results) O34, and the carbon dioxide emissions (disposal results) O35 are displayed.

[0140] The carbon dioxide emission amount (transportation) O13, the carbon dioxide emission amount (use) O14, and the carbon dioxide emission amount (disposal) O15 described using Fig. 7 are predicted values ​​calculated before the footwear desired by the user is manufactured based on the user information U10 and each piece of information stored in the storage unit 110. On the other hand, the carbon dioxide emission amount (transportation record) O33, the carbon dioxide emission amount (use record) O34, and the carbon dioxide emission amount (disposal record) O35 are actual values ​​calculated based on each piece of information when the manufactured footwear (actual product) is actually transported, maintained, and disposed of.

[0141] Carbon dioxide emissions O30 is the sum of carbon dioxide emissions (material results) O21, carbon dioxide emissions (manufacturing results) O22, carbon dioxide emissions (transportation results) O33, carbon dioxide emissions (usage results) O34, and carbon dioxide emissions (disposal results) O35, and indicates the amount of carbon dioxide emitted based on each result value in the life cycle of manufactured footwear (actual product).

[0142] For example, the server device 300 may output the carbon dioxide emission amount O30, the carbon dioxide emission amount (material results) O21, the carbon dioxide emission amount (manufacturing results) O22, the carbon dioxide emission amount (transportation results) O33, the carbon dioxide emission amount (usage results) O34, and the carbon dioxide emission amount (disposal results) O35 shown in FIG. 14, and display them on the screen of the terminal 11 to present them to the user.

[0143] This allows users to properly understand how much carbon dioxide will be emitted from the time their desired footwear is manufactured (including the use of materials) through transportation, use (maintenance), and disposal, based on actual values ​​for each stage of the life cycle.

[0144] Here, the output unit 340 outputs the carbon dioxide emission amount (transportation result) O33, the carbon dioxide emission amount (usage result) O34, and the carbon dioxide emission amount (disposal result) O35 instead of the carbon dioxide emission amount (transportation) O13, the carbon dioxide emission amount (use) O14, and the carbon dioxide emission amount (disposal) O15, but it may output all of them. For example, by checking both, the user can compare the predicted value with the actual value. As a result, the user can recognize that their own behavioral changes affect the carbon dioxide emission amount.

[0145] Furthermore, here, the environmental index calculation unit 330 calculates the carbon dioxide emission amount (transportation result), the carbon dioxide emission amount (use), and the carbon dioxide emission amount (disposal result) based on the transportation record information A30, the usage record information A40, and the disposal record information A50, and the output unit 340 outputs these. For example, when the environmental index calculation unit 330 calculates at least one of the carbon dioxide emission amount (transportation result), the carbon dioxide emission amount (use), and the carbon dioxide emission amount (disposal result) based on at least one piece of record information acquired by the record information acquisition unit 310, the output unit 340 may output the carbon dioxide emission amount based on the calculated at least one piece of record information. For other items, the environmental index calculation unit 330 may output the carbon dioxide emission amount (transportation) O13, the carbon dioxide emission amount (use) O14, and the carbon dioxide emission amount (disposal) O15 described using FIG. 7.

[0146] [Environmental Impact Assessment Method] 15 is a flowchart showing the processing flow of an environmental impact assessment method M300 executed by an environmental impact assessment system 30 according to the third embodiment of the present disclosure. As shown in FIG. 15, the environmental impact assessment method M300 includes steps S110, S120, S210 to S230, and steps S310 to S340, and each step is executed by, for example, a processor included in the server device 300.

[0147] Steps S110 and S120 are the same as steps S110 and S120 in the environmental impact assessment method M100 described with reference to FIG.

[0148] Steps S210 to S230 are the same as steps S210 to S230 in the environmental impact assessment method M200 described with reference to FIG.

[0149] In step S310, the server device 300 determines whether the user information has been updated, and if the user information has been updated ("Yes" in step S310), the server device 300 proceeds to the processing of step S320. Specifically, if the delivery record information, maintenance record information, and disposal record information included in the user information U30 have been input (updated) in the terminal 11, the EC site, and the delivery company system, the server device 300 proceeds to the processing of step S320.

[0150] In step S320, the performance information acquisition unit 310 acquires updated user information (performance information). Specifically, the performance information acquisition unit 310 acquires transportation performance information A30, usage performance information A40, and disposal performance information A50 based on the user information (performance information) input (updated) in the terminal 11, the EC site, and the delivery company system.

[0151] In step S330, the environmental index calculation unit 330 calculates the environmental index (amount of carbon dioxide emission) based on the transportation history information A30, usage history information A40, and disposal history information A50 acquired in step S320. Specifically, the environmental index calculation unit 330 calculates the amount of carbon dioxide emission (second environmental index) using the above-mentioned (Equations 3) to (Equation 5) based on the transportation history information A30, usage history information A40, and disposal history information A50 acquired in step S320.

[0152] In step S340, the output unit 340 outputs (updates) the environmental index (amount of carbon dioxide emission). Specifically, the output unit 340 outputs the amount of carbon dioxide emission (second environmental index) calculated in step S330 together with the amount of carbon dioxide emission (first environmental index and / or second environmental index) output in step S230, or in place of the amount of carbon dioxide emission (first environmental index and / or second environmental index). The output unit 340 may display the amount of carbon dioxide emission (second environmental index) on the screen of the terminal 11 to present it to the user, together with the amount of carbon dioxide emission (first environmental index) or by updating the amount of carbon dioxide emission (first environmental index), as shown in FIG.

[0153] [Effects of the third embodiment] According to an environmental impact assessment system 30 and an environmental impact assessment method M300 according to a third embodiment of the present disclosure, in addition to the environmental impact assessment system 10 according to the first embodiment of the present disclosure, a performance information acquisition unit 310 is provided. The performance information acquisition unit 310 acquires transportation performance information A30, usage performance information A40, and disposal performance information A50 for manufactured footwear (performance products). An environmental index calculation unit 330 calculates a carbon dioxide emission amount (second environmental index) based on the transportation performance information A30, usage performance information A40, and disposal performance information A50. An output unit 340 outputs the carbon dioxide emission amount (second environmental index) together with the carbon dioxide emission amount (first environmental index) or by updating the carbon dioxide emission amount (first environmental index). This makes it possible to appropriately evaluate the carbon dioxide emission amount associated with footwear (products) desired by a user, depending on the circumstances of each piece of footwear, and taking into account the carbon dioxide emission amount resulting from the actual manufacturing (including material use), transportation, use, and disposal of the desired footwear.

[0154] <Variation 1> 16 is a diagram showing predicted and actual values ​​of material information and manufacturing information of footwear (products) desired by a user before and after manufacturing of the footwear (products). As shown in FIG. 16, there is a difference between the material prediction information and manufacturing prediction information before manufacturing the footwear and the material actual information and manufacturing actual information for the manufactured footwear.

[0155] The material prediction information is information including materials (material type and weight used) required to manufacture footwear desired by the user, and is generated, for example, by the prediction information generation unit 120 based on the information stored in the storage unit 110. In other words, the material prediction information is a predicted value before the footwear is actually manufactured.

[0156] The material actual information is information including the materials (material type and weight used) used in the manufactured footwear. In other words, the material actual information is the actual value of the footwear actually manufactured, and there is a difference when compared with the material forecast information, which is a forecast value.

[0157] The production forecast information is information including the processing time, fuel consumption, rated power, and thermal efficiency required to manufacture the footwear desired by the user, and is generated, for example, by the forecast information generation unit 120 based on the information stored in the storage unit 110. In other words, the production forecast information is a predicted value before the footwear is actually manufactured.

[0158] The production performance information includes the processing time, fuel consumption, rated power, and thermal efficiency required to manufacture the footwear. In other words, the production performance information is the actual values ​​of the footwear that have actually been manufactured, and there is a difference when compared with the production forecast information, which is a forecast value.

[0159] The environmental impact assessment system according to the present disclosure may include a prediction model that is updated by learning the difference between material prediction information and material performance information, and the difference between production prediction information and production performance information, and may be configured to be able to access the prediction model from an external system. The prediction information generator 120 may then generate material prediction information and production prediction information using the prediction model.

[0160] [Effects of Modification Example 1] As described above, by using a prediction model that is updated by learning the difference between predicted values ​​and actual values, the accuracy of the material prediction information and production prediction information generated by the prediction information generation unit 120 is improved. The environmental index calculation unit 130 calculates the carbon dioxide emission amount based on the material prediction information and production prediction information generated by the prediction information generation unit 120, and therefore the accuracy of the calculated carbon dioxide emission amount is also improved. As a result, the user can grasp the carbon dioxide emission amount calculated with high accuracy even before the footwear (product) is manufactured.

[0161] Although material information and manufacturing information have been used as examples in the explanation here, the present invention is not limited to these. For example, a prediction model that is updated by learning the difference between predicted values ​​and actual values ​​for transportation information, usage information, and disposal information may be used.

[0162] <Variation 2> Fig. 17 is a diagram showing an example of outputting the amount of carbon dioxide emissions (assigned a grade) emitted throughout the life cycle of footwear, from its manufacture (including material use) to its disposal, as an environmental index. As shown in Fig. 17, a grade is assigned to each process in the life cycle of the footwear (product) and to the overall amount of carbon dioxide emissions. Here, the grade indicates the reliability as an environmental index.

[0163] The environmental impact assessment system according to the present disclosure may include a grade determination unit that determines a grade. The grade determination unit may determine a grade that indicates the reliability of the carbon dioxide emissions calculated by the environmental index calculation unit 130, 230, 330.

[0164] For example, when the forecast information generating unit 120 generates forecast information using the forecast model, the grade determining unit may assign a higher grade to the carbon dioxide emissions calculated by the environmental index calculating unit 130 based on the forecast information, depending on the number of times the forecast model has been updated. Furthermore, when calculating the overall carbon dioxide emissions, the grade determining unit may assign a higher grade depending on the proportion of the performance information acquired by the performance information acquiring units 210 and 310 that was used to calculate the carbon dioxide emissions in each process. Alternatively, a similar evaluation can be performed for the basic unit. For example, reliability can be further improved by using basic unit data based on the results of LCA (Life Cycle Assessment) specific to each supplier, rather than basic unit data based on the industry average.

[0165] 17, the grade determination unit assigns a high grade [A] to the carbon dioxide emission amount (material results) O21, the carbon dioxide emission amount (manufacturing results) O22, and the carbon dioxide emission amount (transportation results) O33 because they are calculated using performance information. The grade determination unit assigns a grade [B] to the carbon dioxide emission amount O40 because it includes the carbon dioxide emission amount (manufacturing results) O22 and the carbon dioxide emission amount (transportation results) O33 of grade [A], but also includes the carbon dioxide emission amount (use) and the carbon dioxide emission amount (disposal) of grade [B].

[0166] [Effects of Modification Example 2] As described above, if a grade is assigned to the carbon dioxide emission calculated by the environmental index calculation units 130, 230, 330 and displayed on the screen of the terminal 11, for example, and presented to the user, the user can understand the reliability of the carbon dioxide emission for each process in the life cycle of the footwear (product) and for the entire life cycle. Furthermore, if the user inputs performance information, the grade of the carbon dioxide emission calculated based on the performance information can be improved, which can also be an element that encourages the user to input performance information.

[0167] <Variation 3> The environmental impact assessment system according to the present disclosure may include a lifespan prediction unit that predicts the lifespan of footwear (products). The environmental impact assessment system according to the present disclosure has various information for calculating carbon dioxide emissions, and the lifespan prediction unit may predict the lifespan of footwear (products) using this information.

[0168] For example, the lifespan prediction unit can predict the lifespan of the footwear based on the physical information (height, weight, foot size and shape) and product information (product type, product shape and color) contained in the user information U10 shown in Figure 3.

[0169] The lifespan prediction unit can accurately predict the lifespan of the footwear by taking into account maintenance information (cleaning method, cleaning frequency, repair method, and storage method) and usage information (purpose of use, distance traveled, running speed, and storage method).

[0170] Furthermore, the lifespan prediction unit may update the predicted lifespan of the footwear by taking into account performance information from the user. For example, the lifespan prediction unit can more accurately predict the lifespan of the footwear based on performance information on maintenance (cleaning method, cleaning frequency, repair method, and storage method) and performance information on usage (purpose of use, mileage, running speed, and storage method) included in the user information U30 shown in FIG.

[0171] [Effects of Modification 3] As described above, if the lifespan of footwear (products) is presented to the user, the user can appropriately determine the timing for replacing the footwear (products).

[0172] Furthermore, since the predicted lifespan of the footwear is updated based on performance information from the user, the user can recognize that their own behavioral changes affect the lifespan of the footwear (product). The environmental impact assessment system according to the present disclosure may provide the user with factors that can extend the lifespan of the footwear (product).

[0173] Furthermore, a prediction model may be used for the lifespan of footwear, which is updated by learning a predicted value immediately after the manufacture of the footwear, a predicted value (updated value) that takes into account performance information from the user, and a performance value at the time of final disposal. This allows the user to accurately grasp the lifespan of the footwear at an early stage after starting to use the footwear.

[0174] In other words, accuracy is improved by using machine learning with a regression model on a set of actual input and output data. For example, during use, the user's input lifespan and maintenance frequency (including cleaning) can be predicted, and environmental impact assessments (including calculations of carbon dioxide emissions) can be performed based on the predicted data. Furthermore, when purchasing a new product, past performance data can be linked through individual identification and compared with the predicted data, further increasing accuracy.

[0175] [Summary of the effects of this disclosure] According to the present disclosure, the environmental impact of a product desired by a user can be appropriately evaluated according to the circumstances of each product by calculating the carbon dioxide emissions over the product's life cycle.

[0176] In each embodiment of the present disclosure, the environmental indicators (first and second environmental indicators) are exemplified by carbon dioxide emissions, but are not limited thereto. For example, indicators for evaluating the environmental burden of a product or corporate activity may be obtained based on at least one of the following, as defined in Environmental Footprint (EF) 3.0: carbon dioxide emissions, impact on land and soil, fossil fuel consumption, mineral and metal consumption, water consumption, impact on freshwater ecosystems, nutrient emissions into freshwater systems, impact on acidification, nutrient emissions into marine systems, nutrient emissions into terrestrial ecosystems, photochemical ozone emissions, impact on the respiratory system, emissions of radioactive materials, emissions of carcinogenic substances, emissions of non-carcinogenic toxic substances and deleterious substances, and impact on ozone layer depletion.

[0178] Furthermore, since the product management system 400 according to an embodiment of the present disclosure can manage product manufacturers, etc., it is possible to take measures against counterfeit products, for example, by identifying counterfeit products, etc. For example, the administrator of the product management system 400 can identify, as counterfeit products, products that do not have the identification information attached to genuine products, products that have identification information different from that of genuine products, or products that cannot be associated with product management information that manages genuine products.
