[0010] According to conventional systems such as the above-mentioned Patent Document 1, information indicating greenhouse gas emissions can be provided for each product. A user can refer to the provided information, compare the greenhouse gas emissions for each product, and select a product with a low greenhouse gas emission, thereby contributing to the reduction of greenhouse gas emissions.

[0011] However, in conventional systems, information on greenhouse gas emissions is provided on a product-by-product basis, so even if users can select products with low emissions, the factors that lead to low greenhouse gas emissions for those products are unclear. In other words, conventional systems do not visualize the factors that reduce greenhouse gas emissions through product selection behavior, and it takes time for users to confirm those factors.

[0012] In response to this, an information processing device according to a first aspect of the present disclosure includes a control unit configured to receive a product search request from a user terminal, extract product information for a product corresponding to the received request from a product database, the product information including emission information indicating the greenhouse gas emissions of each component that constitutes the product, and return the extracted product information to the user terminal so that the emission information can be output for each component of the product.

[0013] The information processing device according to the first aspect of the present disclosure provides information indicating the amount of greenhouse gas emissions for each component constituting a product. This allows the greenhouse gas emissions of each product to be compared on a component-by-component basis. In this comparison, it is possible to identify one of the factors that cause the target product to have low greenhouse gas emissions by identifying the components contained in the target product that have low greenhouse gas emissions compared to other products. In other words, it is possible to identify that the inclusion of the component is one of the factors that cause the target product to have reduced greenhouse gas emissions. Therefore, according to the information processing device according to the first aspect of the present disclosure, it is possible to visualize at least a part of the factors that cause the reduction in greenhouse gas emissions due to the product selection behavior. As a result, it is possible to reduce the effort required for the user to confirm the factors.

[0014] Hereinafter, an embodiment according to one aspect of the present disclosure (hereinafter also referred to as "the present embodiment") will be described with reference to the drawings. However, the present embodiment described below is merely an example of the present disclosure in all respects. Various improvements or modifications may be made without departing from the scope of the present disclosure. In implementing the present disclosure, a specific configuration according to the embodiment may be appropriately adopted. Note that while the data appearing in this embodiment is described in natural language, more specifically, it is specified in pseudo-language, commands, parameters, machine language, etc. that can be recognized by a computer.

[0015] [1 Application example] 1 is a schematic diagram illustrating an example of a situation in which the present disclosure is applied. An information processing device 1 according to the present embodiment is one or more computers configured to execute information processing for providing product information in response to a request from a user.

[0016] Specifically, the information processing device 1 according to this embodiment receives a product search request 50 from the user terminal 2. The information processing device 1 extracts product information 55 of a product corresponding to the received request 50 from the product database 30. The product information 55 is configured to include emission information indicating the greenhouse gas emission amount of each component that constitutes the product. The information processing device 1 returns the extracted product information 55 to the user terminal 2 so that the emission information can be output for each component of the product. Outputting the emission information for each component may be configured by outputting the greenhouse gas emission amount for each component.

[0017] As described above, according to this embodiment, it is possible to provide information (emission information) indicating the amount of greenhouse gas emissions for each component constituting a product. This makes it possible to compare the greenhouse gas emissions between products on a component-by-component basis. In this comparison, it is possible to identify one of the factors that cause the target product to have low greenhouse gas emissions by identifying the components contained in the target product that have low greenhouse gas emissions compared to other products. Therefore, according to this embodiment, it is possible to visualize at least some of the factors that contribute to the reduction of greenhouse gas emissions due to product selection behavior. As a result, it is possible to reduce the effort required for the user to check the factors.

[0018] (product / component) A commodity is an item that can be the subject of commerce. A commodity may be any item, such as food, beverage, or electrical appliance. The number of items treated as commodities is not particularly limited and may be determined appropriately depending on the embodiment. As an example, consider a case where 24 plastic bottles of water are sold together. In this case, as an example, the 24 plastic bottles of water may be regarded as one commodity. As another example, one plastic bottle of water may be regarded as one commodity, and the 24 plastic bottles of water may be regarded as 24 commodities.

[0019] A component of a product is an item that constitutes at least a part of the product. The unit of a component may be appropriately determined depending on the embodiment. A component may be an item that can be understood as a single unit. As an example, if the product is water enclosed in a plastic bottle container with a label, the components of the product may be water, the plastic bottle container, and the label.

[0020] For example, a plurality of items may be packaged together and sold, such as a dozen or 24 pieces. Also, a single product may be packaged together with accessories, instructions, etc., and sold, such as an electrical appliance. When packaging is used as in these examples, each component of the product may include the packaging. The packaging may be, for example, paper, cardboard, vinyl, styrofoam, etc. When multiple types of packaging are used, each packaging may be handled individually or at least partially as a single unit. This allows the greenhouse gas emissions caused by the packaging to be visualized.

[0021] (request) The request 50 (query) includes a condition for searching for a product. The search condition may be specified by any method including a known method. As an example, the search condition may be specified by a character string (e.g., product name, content, etc.), a category, an attribute (e.g., price range, size, color scheme, material, brand, evaluation value, etc.), etc. The information processing device 1 refers to the product database 30 and searches for the request 50. The product database 30 is configured to extract product information 55 of products that meet the conditions specified by the above. The configuration and search method of the product database 30 may employ any method, including known methods.

[0022] (Greenhouse gases) A typical example of the greenhouse gas is carbon dioxide. In addition, the greenhouse gas may include gases that cause the greenhouse effect, such as methane, nitrous oxide, fluorocarbons, sulfur hexafluoride, and sulfur trifluoride. As shown in FIG. 1, in this embodiment, for the sake of convenience, carbon dioxide (CO 2 ) is used as an example of the greenhouse gas. 2 ) is adopted. However, the greenhouse gas for which the emissions are outputted does not have to be limited to carbon dioxide, and may be appropriately selected depending on the embodiment. The greenhouse gas for which the emissions are outputted may be composed of one or more types of gas. In one example, the greenhouse gas for which the emissions are outputted may be composed of carbon dioxide, methane, nitrous oxide, fluorocarbons, sulfur hexafluoride, sulfur trifluoride, or a combination thereof.

[0023] The greenhouse gas emissions of each component may be measured as appropriate depending on the embodiment. In one example, the greenhouse gas emissions of each component may be calculated by measuring the amount of greenhouse gases emitted in the process of obtaining each component, such as procurement, production, etc.

[0024] (Product information) The product information stored in the product database 30 may have any data format and structure that is not particularly limited and may be appropriately determined depending on the embodiment, so long as it includes emission information indicating the greenhouse gas emission amount of each component that constitutes the product. The product information may include information such as product description, price, and product image in addition to the emission information.

[0025] In the user terminal 2, the product information 55 of each extracted product may be output in any format including known formats such as a list format, a table format, etc. Also, the product information 55 including the emission information may be output in any format including known formats such as an image display, an audio output, etc. As long as the emission information includes the greenhouse gas emission amount of each component, the data format and configuration are not particularly limited and may be appropriately determined depending on the embodiment.

[0026] (Items eligible for recycling) Each component of the product may include an item to be recycled (i.e., an item that can be recycled). The item to be recycled may be determined appropriately depending on the embodiment. The item to be recycled may be, for example, paper, aluminum, copper, iron, glass, PET bottles, batteries, etc.

[0027] When a component of a product includes an item that is eligible for recycling, the emission information of the product may include first comparison information indicating a difference between the amount of greenhouse gas emissions when the item is recycled and the amount of greenhouse gas emissions when the item is not recycled. In addition, the output of the emission information may include an output of the first comparison information. This makes it possible to visualize the contribution of recycling to reducing greenhouse gas emissions.

[0028] The data format of the first comparison information is not particularly limited as long as it is possible to grasp the difference in greenhouse gas emissions between when the target item is recycled and when it is not recycled, and may be appropriately determined depending on the embodiment. In one example, the first comparison information may be composed of information indicating the greenhouse gas emissions of the target item and the reduction in greenhouse gas emissions when the target item is recycled. In another example, the first comparison information may be composed of information indicating the greenhouse gas emissions of the target item when the target item is recycled and the greenhouse gas emissions of the target item when it is not recycled.

[0029] The first comparison output is the greenhouse effect of recycling and not recycling. As long as the difference in the amount of gas emissions can be grasped, the form is not particularly limited and may be appropriately determined depending on the embodiment. In one example, outputting the first comparison information may be configured by outputting the greenhouse gas emissions of the target item and the amount of reduction due to recycling. In another example, outputting the first comparison information may be configured by outputting the greenhouse gas emissions of the target item in each of the cases where the item is recycled and where the item is not recycled. When any of the above examples of the data format of the first comparison information is adopted, any of the examples of the output form may be adopted.

[0030] (Recycling items) Each component of the product may include a recycled item produced from recycled materials. Recycled materials are materials obtained by recycling. The type and use of the recycled materials may be appropriately determined depending on the embodiment. Note that producing from recycled materials may include using recycled materials for at least a portion of the components (recycled items) of the product.

[0031] When a component of a product includes a recycled item, the emission information of the product may include second comparison information indicating the difference between the greenhouse gas emission amount of the recycled item and the greenhouse gas emission amount when the recycled item is replaced with a virgin item made from virgin material (i.e., the recycled item is not used). In addition, the output of the emission information may include the output of the second comparison information. This makes it possible to visualize the contribution to reducing greenhouse gas emissions by selecting a product including a recycled item. Note that virgin material is a material obtained from new materials. Replacing with a virgin item is equivalent to using a virgin item as the same component as the recycled item in the target product.

[0032] The data format of the second comparison information is not particularly limited as long as it is possible to grasp the difference in greenhouse gas emissions between when recycled goods are used and when recycled goods are not used (i.e., when virgin goods are used), and may be appropriately determined depending on the embodiment. In one example, the second comparison information may be composed of information indicating the greenhouse gas emissions of recycled goods and the reduction in greenhouse gas emissions resulting from replacing virgin goods with recycled goods (i.e., when recycled goods are used instead of virgin goods in the product). In another example, the second comparison information may be composed of information indicating the greenhouse gas emissions of recycled goods and the greenhouse gas emissions of virgin goods.

[0033] The output of the second comparison information may be in any form, as long as it is possible to grasp the difference in greenhouse gas emissions between when recycled goods are used and when recycled goods are not used, and may be appropriately determined depending on the embodiment. In one example, outputting the second comparison information may be configured by outputting the greenhouse gas emissions of the recycled goods and the reduction amount due to the use of the recycled goods. In another example, outputting the second comparison information may be configured by outputting the greenhouse gas emissions of the recycled goods and the greenhouse gas emissions of the virgin goods. When any of the above examples of the data format of the second comparison information is adopted, any of the examples of the output form may be adopted.

[0034] (Compared to other products) In the product database 30, greenhouse gas emissions may be compared between corresponding components of the same type of product. As a result of this comparison, flag information indicating that a product contains a component that emits a large amount of greenhouse gas compared to other products may be given to the product.

[0035] In other words, if the greenhouse gas emissions of the target component contained in a product are greater than the greenhouse gas emissions of the same component contained in other products of the same type as the product in question, the emissions The emission information may include flag information indicating that the greenhouse gas emission of the target component is higher than the greenhouse gas emission of the same component contained in other products. In addition, the output of the emission information may include the output of flag information. This makes it possible to visualize whether or not a component with a higher greenhouse gas emission is included compared to other products.

[0036] The identical component contained in the other product is a component of the same type as the target component contained in the target product. For example, if the target component is a plastic bottle container, the identical component is a plastic bottle container used in the other product.

[0037] The criteria for determining that a product is more than other products may be appropriately determined depending on the embodiment. In one example, a product that is more than other products may be a product other than the product with the lowest number, a product that is more than the product with the lowest number by a threshold or more, or a product that is the most. The threshold may be appropriately set.

[0038] The output of the flag information may be in any form, as long as it is possible to grasp that the greenhouse gas emissions of the target component are greater than those of other products, and may be appropriately selected according to the embodiment. The output of the flag information may be, for example, configured by changing the display form (e.g., changing the type of text, changing the color of text, etc.), outputting a sentence indicating that the emissions are greater than those of other products, etc.

[0039] (User terminal) The user terminal 2 is one or more computers used by a user. The user terminal 2 may be a computer designed specifically for the service provided, a desktop PC (Personal Computer), a mobile phone including a smartphone, a tablet PC, or any other general-purpose computer. The input device may be a computer, etc.

[0040] 1, the information processing device 1 and the user terminal 2 may be connected to each other via a network. The type of network may be appropriately selected from, for example, the Internet, a wireless communication network, a mobile communication network, a telephone network, a dedicated network, etc. Any method including a publicly known method may be adopted for data communication between the information processing device 1 and the user terminal 2.

[0041] [2 Configuration example] [Hardware configuration example] Fig. 2 is a schematic diagram showing an example of a hardware configuration of the information processing device 1 according to the present embodiment. As shown in Fig. 2, the information processing device 1 according to the present embodiment is a computer in which a control unit 11, a storage unit 12, a communication interface 13, an input device 14, an output device 15, and a drive 16 are electrically connected.

The program 81 includes a series of instructions for the information processing. The product database 30 stores product information in a searchable format. is doing.

[0045] The communication interface 13 is, for example, a wired LAN (Local Area Network) module, a wireless LAN module, etc., and is an interface for performing wired or wireless communication via a network. The information processing device 1 can perform data communication with other computers (for example, the user terminal 2) using the communication interface 13.

[0046] The input device 14 is a device for performing input, such as a mouse, a keyboard, etc. The output device 15 is a device for performing output, such as a display, a speaker, etc. An operator can operate the information processing device 1 by using the input device 14 and the output device 15. The input device 14 and the output device 15 may be integrally configured, for example, by a touch panel display, etc.

[0047] The drive 16 is a device for reading various information such as programs stored in a storage medium 91. At least one of the above-mentioned program 81 and the product database 30 may be stored in the storage medium 91. The storage medium 91 is a medium that accumulates information such as programs by electrical, magnetic, optical, mechanical or chemical action so that a computer or other device, machine or the like can read the various information such as the stored programs. The information processing device 1 may acquire at least one of the program 81 and the product database 30 from the storage medium 91.

[0048] 2 illustrates a disk-type storage medium such as a CD or a DVD as an example of the storage medium 91. However, the type of the storage medium 91 is not limited to the disk type, and may be other than the disk type. An example of a storage medium other than the disk type is a semiconductor memory such as a flash memory. The type of the drive 16 may be appropriately selected depending on the type of the storage medium 91.

[0049] In addition, regarding the specific hardware configuration of the information processing device 1, components can be omitted, replaced, or added as appropriate depending on the embodiment. For example, the control unit 11 may include multiple hardware processors. The hardware processor may be a microprocessor, a field-programmable gate array (FPGA), a graphics processing unit (GPU), etc. At least one of the communication interface 13, the input device 14, the output device 15, and the drive 16 may be omitted.

[0050] The information processing device 1 may further include an external interface for connecting to an external device. The external interface is, for example, a USB (Universal Serial Bus) port, a dedicated port, etc. The type and number of the external interfaces may be appropriately determined according to the type and number of the connected external devices. The information processing device 1 may be connected to another computer via the external interface. The information processing device 1 may also be connected to an external storage device via the external interface. In this case, at least one of the program 81 and the product database 30 may be stored in the external storage device. The information processing device 1 may acquire at least one of the program 81 and the product database 30 from the external storage device.

[0051] The information processing device 1 may be configured with a plurality of computers. In this case, the hardware configurations of the computers may or may not be the same. The information processing device 1 may be configured with any computer capable of executing information processing. The information processing device 1 may be a computer designed specifically for the service provided, a general-purpose server device, a general-purpose PC (Personal Computer), etc.

[0052] [Software configuration example] 3 shows a schematic diagram of an example of a software configuration of the information processing device 1 according to the present embodiment. The control unit 11 of the information processing device 1 loads the program 81 stored in the storage unit 12 in the RAM. Then, the control unit 11 executes instructions included in the program 81 loaded in the RAM by the CPU. As a result, as shown in FIG. 3, the information processing device 1 according to the present embodiment operates as a computer including a receiving unit 111, a searching unit 112, and an output unit 113 as software modules. That is, in the present embodiment, each software module of the information processing device 1 is realized by the control unit 11 (CPU).

[0053] The receiving unit 111 is configured to receive a product search request 50 from the user terminal 2. The searching unit 112 is configured to extract product information 55 of a product corresponding to the received request 50, the product information 55 including emission information indicating the greenhouse gas emission amount of each component that constitutes the product, from the product database 30. The output unit 113 is configured to return the extracted product information 55 to the user terminal 2 so that the emission information can be output for each component of the product.

[0054] In the present embodiment, an example is described in which each software module of the information processing device 1 is realized by a general-purpose CPU. However, some or all of the above software modules may be realized by one or more dedicated processors. Each of the above modules may be realized as a hardware module. With regard to the software configuration of the information processing device 1, modules may be omitted, replaced, or added as appropriate depending on the embodiment.

[0055] (Product database) Fig. 4 is a schematic diagram showing an example of the product database 30 according to the present embodiment. In the example shown in Fig. 4, the product database 30 has a data structure in a table format. The product data shown in Fig. 4 corresponds to product information for one product. The product data has fields for storing the product name, components, emissions, flag, recycling flag, recycled reduction amount, recycled product flag, and recycled product reduction amount.

[0056] The product name field stores information indicating the name of the product. The component field stores information indicating each component that makes up the product. The emission amount field stores information indicating the greenhouse gas emissions of the target component. The "total" record stores the total greenhouse gas emissions of each component.

[0057] The flag field stores information indicating whether the greenhouse gas emissions of the target component are greater or less than the greenhouse gas emissions of the same component contained in other products. "1" indicates that the greenhouse gas emissions of the target component are greater than the greenhouse gas emissions of the same component contained in other products, and "0" indicates that the emissions are less.

[0058] The recycle flag field stores information indicating whether the target component is a recycle target item or not. "1" indicates that the target component is a recycle target item, and "0" indicates that it is not. The recycle reduction amount field stores information indicating the reduction amount of greenhouse gas emissions when the target item is recycled.

[0059] The recycled product flag field stores information indicating whether the target component is a recycled product made from recycled materials. "1" indicates that the target component is a recycled product, and "0" indicates that it is not (i.e., the target component is a virgin product). The recycled product reduction amount field stores the amount of warming caused by using recycled products (i.e., replacing virgin products with recycled products). Information indicative of the reduction in greenhouse gas emissions is stored.

[0060] In the example of Fig. 4, for the fields after the component, a record (row data) is provided for each component, and various information of each component is stored in each record. Information stored in each field from the discharge amount to the recycled product reduction amount is an example of discharge information. Information stored in the flag field is an example of flag information.

[0061] The information stored in the emission amount field and the recycled reduction amount field is an example of first comparison information. That is, in the example of Fig. 4, the first comparison information is composed of information indicating the greenhouse gas emission amount of the target item when the target item is not recycled and the greenhouse gas emission reduction amount when the target item is recycled.

[0062] The information stored in the emission amount field and the recycled product reduction amount field is an example of second comparison information. That is, in the example of Fig. 4, the second comparison information is composed of information indicating the greenhouse gas emission amount of recycled products and the reduction amount of greenhouse gas emissions by replacing virgin products with recycled products.

[0063] In the example of FIG. 4, the following conditions are assumed as a specific example of a product. That is, the product "Water A" has the water itself, a PET bottle container, a label, and packaging material as its components. Of these components, the PET bottle container, label, and packaging material are items eligible for recycling. While the label and packaging material are recyclable items, the water itself and the PET bottle container are virgin items. The greenhouse gas emissions of the PET bottle container of "Water A" are greater than the greenhouse gas emissions of the same component (PET bottle container) contained in another product (water) of the same type as "Water A". However, these conditions are merely specific examples for the sake of convenience of explanation, and do not limit the contents of this disclosure.

[0064] The data format of the product database 30 does not need to be limited to the example shown in Fig. 4. As long as the product database 30 stores product information in a searchable state, the data format is not particularly limited and may be appropriately determined depending on the embodiment. Furthermore, the product information stored in the product database 30 may include information other than the information shown in Fig. 4. The product information may include, for example, product description, product image, price, other attributes, and other information.

[0065] 4, in the flag field, the recycle flag field, and the recycle product flag field, a flag is set and a flag is not ...

[0066] [3 Example of operation] 5 is a flowchart showing an example of a processing procedure of the information processing device 1 according to the present embodiment. The processing procedure described below is an example of an information processing method according to one aspect of the present disclosure. However, the processing procedure described below is merely an example, and each step may be changed as much as possible. In addition, steps may be omitted, replaced, or added to the following processing procedure as appropriate depending on the embodiment.

[0067] (Step S101) In step S101, the control unit 11 operates as the receiving unit 111 and receives a product search request 50 from the user terminal 2.

[0068] The method of inputting product search conditions in the user terminal 2 and the method of transmitting the request 50 from the user terminal 2 to the information processing device 1 may be any method, including known methods. In an example, the user terminal 2 may accept the designation of search conditions via an input device. The search conditions may be designated by, for example, a character string, a category, an attribute, or the like. The user terminal 2 may transmit a request 50 including the designated search conditions to the information processing device 1 via a network using a communication interface. Upon receiving the request 50 from the user terminal 2, the control unit 11 advances the process to the next step S102.

[0069] (Step S102) In step S102, the control unit 11 operates as the search unit 112, refers to the product database 30, and extracts product information 55 of products that meet the conditions specified in the request 50 from the product database 30.

[0070] The method of extracting (searching) the product information 55 in the product database 30 may be determined appropriately depending on the data format of the product database 30, etc. Any method including known methods may be adopted as the extraction method. In one example, when a product name is specified as a search condition, the control unit 11 may extract the product information 55 by referring to the value in the product name field and searching for product data that stores a value that meets the specified condition. As described above, the product data may store other information such as a product description and price, and the control unit 11 may extract the product information 55 based on this other information. When the product information 55 of the product that meets the request 50 is extracted, the control unit 11 proceeds to the next step S103.

[0071] (Step S103) In step S103, the control unit 11 operates as the output unit 113 and returns the extracted product information 55 to the user terminal 2 so that discharge information can be output for each component of the product. In response, the user terminal 2 receives the product information 55 and outputs the received product information 55. In one example, the user terminal 2 includes an output device such as a display, and outputs the product information 55 to the output device. However, the output destination of the product information 55 is not limited to this example, and may be determined appropriately depending on the embodiment.

[0072] Any method including known methods may be adopted as a method for returning the product information 55 to the user terminal 2. In this embodiment, the control unit 11 may use the communication interface 13 to transmit the product information 55 of the extracted product to the user terminal 2 via a network. In the user terminal 2, the product information 55 may be output in any format including known formats such as image display, audio output, etc. The output method and output form may be appropriately determined depending on the embodiment.

[0073] Fig. 6 shows a schematic example of an output form (screen display) of product information 55 in the user terminal 2 according to this embodiment. The example in Fig. 6 assumes a scene in which product information 55 for "Water A" in Fig. 4 is output by screen display on the output device 20 (display) of the user terminal 2. The output screen of the product information 55 may be generated by a known method such as HTML (Hyper Text Markup Language) or XML (Extensible Markup Language).

[0074] In this example of the screen display, the value of the emission amount field of the product information 55 is displayed in the area 200, and the greenhouse gas emission amount is output for each component. In the example of FIG. 6, the component of "Water A" includes packaging material, and the greenhouse gas emission amount of the packaging material is displayed in the area 200. Note that multiple items may be sold together as one product. In this case, in one example, the greenhouse gas emission amount of each component may be output at least either for each individual item or for each product (i.e., the total for the multiple items). The user may specify whether to display the amount for each individual item or for each product (in one example, the display form may be switchable on the screen at the user's instruction).

[0075] In balloon 210, the value of the recycled reduction amount field of product information 55 is displayed, thereby outputting the amount of greenhouse gas reduction caused by recycling the item to be recycled (PET bottle containers in the example of FIG. 6). The output of information in area 200 and balloon 210 is an example of output of first comparison information. The output of information in area 200 and balloon 210 visualizes the contribution of recycling to reducing greenhouse gas emissions.

[0076] In speech bubble 220, the value of the recycled item reduction amount field of product information 55 is displayed, thereby outputting the reduction amount due to the use of recycled items (labels in the example of FIG. 6). The output of information in area 200 and speech bubble 220 is an example of output of second comparison information. The output of information in area 200 and speech bubble 220 visualizes the contribution to reducing greenhouse gas emissions by selecting products that include recycled items.

[0077] Area 200 includes area 230 that outputs information indicating the greenhouse gas emissions of the PET bottle container. In the example of FIG. 4, it is assumed that the greenhouse gas emissions of the PET bottle container, among the components of "Water A," are greater than the greenhouse gas emissions of the same components contained in other products of the same type. That is, in the record of the PET bottle container, the value of the flag field is "1." In response to this, in area 230, the greenhouse gas emissions of the PET bottle container are output in a display form different from that of the other components (the water itself, the label, and the packaging material). The output of information in area 230 is an example of output of flag information.

[0078] 4, the emission amount of PET bottle containers is displayed in a different color scheme and font type from the emission amount of other components as a different display form. However, the different display form is not limited to this example and may be appropriately determined depending on the embodiment as long as it is possible to distinguish between components that emit more greenhouse gases than other products and components that do not.

[0079] Fig. 7 is a schematic diagram showing another example of an output form (screen display) of product information 55 in a user terminal 2 according to this embodiment. In the example shown in Fig. 7, each speech bubble (210, 220) in which each piece of comparison information is output is replaced with each speech bubble (215, 225) employing a different output form. Except for these points, the screen shown in Fig. 7 is configured in the same way as Fig. 6.

[0080] In the speech bubble 215, the amount of greenhouse gas emissions of the target item when recycled is output (PET bottle containers in the example of FIG. 7). The amount of greenhouse gas emissions when recycled may be calculated by subtracting the value in the recycling reduction amount field from the value in the emission amount field. This calculation process may be executed by the information processing device 1 or the user terminal 2. Meanwhile, in the area 200, the amount of greenhouse gas emissions of the target item when not recycled is output. The output of information in the area 200 and the speech bubble 215 is another example of the output of first comparison information. The output of information in the area 200 and the speech bubble 215 visualizes the contribution of recycling to reducing greenhouse gas emissions.

[0081] In the balloon 225, the greenhouse gas emission amount of the virgin product is output (in the example of FIG. 7, a label). The greenhouse gas emission amount when using a virgin product may be calculated by adding the value in the emission amount field to the value in the recycled product reduction amount field. This calculation process may be executed by the information processing device 1 or the user terminal 2. Meanwhile, in the area 200, the greenhouse gas emission amount of the recycled product is output. The output of information in area 200 and speech bubble 225 is another example of output of second comparison information. The output of information in area 200 and speech bubble 225 visualizes the contribution to reducing greenhouse gas emissions by selecting products including recycled goods.

[0082] The output of information shown in Figures 6 and 7 is an example of outputting discharge information for each component of a product. However, the output form shown in Figures 6 and 7 is merely an example for convenience of explanation, and the output form of product information 55 (screen design, order of audio output, etc.) does not have to be limited to such an example.

[0083] In another example, either the first comparison information or the second comparison information may be output in the format of FIG. 6, and the other may be output in the format of FIG. 7. When multiple recycling target items are included, the first comparison information for each target item may be output individually, as shown in FIG. 6 and FIG. 7. Alternatively, the first comparison information for at least some of the target items may be output all at once. When multiple recycling items are included, the second comparison information for each recycling item may be output individually, or the second comparison information for at least some of the recycling items may be output all at once.

[0084] When the product information 55 includes the first comparison information, the first comparison information may be output by a user's instruction (for example, placing the cursor over the name of the component on the screen of FIG. 6 or FIG. 7), or may be output independently of the user's instruction. When the product information 55 includes the second comparison information, the second comparison information may be output by a user's instruction, or may be output independently of the user's instruction. The form in which the first comparison information and the second comparison information are output does not have to be limited to a speech bubble, and may be appropriately selected depending on the embodiment. In addition, the output of the flag information does not have to be limited to a change in the display form exemplified in FIG. 6 and FIG. 7. In another example, the flag information may be output as a sentence indicating that there is more of the product compared to other products.

[0085] After returning the product information 55 to the user terminal 2, the control unit 11 ends the processing procedure according to this operation example. The control unit 11 may wait to execute the processing of step S101 until it receives the request 50 from the user terminal 2. Then, in response to receiving the request 50 from the user terminal 2, the control unit 11 may execute the processing of steps S102 and S103. Thereby, the control unit 11 may repeatedly execute the processing of steps S101 to S103. In other words, the information processing device 1 may be configured to continuously execute information processing for returning product information 55 in response to a request 50 from a user.

[0086] [Features] The information processing device 1 according to the present embodiment can provide product information 55 including emission information indicating the greenhouse gas emission amount for each component of a product by the processing of steps S101 to S103. This allows the greenhouse gas emission amount to be compared between products on a component-by-component basis based on the provided information (examples of which are shown in Figs. 6 and 7). In this comparison, it is possible to identify one of the factors that cause the greenhouse gas emission amount of the target product to be low by finding that the greenhouse gas emission amount of the components included in the target product is low compared to other products. Therefore, according to the present embodiment, it is possible to visualize at least a part of the factors of the reduction in greenhouse gas emission due to the product selection behavior. As a result, it is possible to reduce the effort required for the user to confirm the factors.

[0087] [4 Variations] Although the embodiment of the present disclosure has been described above in detail, the above description is merely an example of the present disclosure in every respect. It goes without saying that various improvements or modifications can be made without departing from the scope of the present disclosure. For example, the following modifications are possible. In the following, the same reference numerals are used for components similar to those in the above embodiment, and the same reference numerals are used for the components similar to those in the above embodiment. The following modifications can be combined as appropriate.

[0088] <4.1> In the above embodiment, the product database 30 is stored in a storage device (the storage unit 12, the external storage device, the storage medium 91, etc.) of the information processing device 1. However, the storage destination of the product database 30 need not be limited to this example. In another example, the product database 30 may be stored in another computer such as a network server. In this case, in the above step S102, the control unit 11 may access the product database 30 by connecting to the other computer via a network or the like, and extract the product information 55 from the product database 30 (the product information 55 may be extracted by the other computer).

[0089] <4.2> In the example of Fig. 4 of the above embodiment, the first comparison information is composed of information indicating the greenhouse gas emission amount of the target item if it is not recycled and the reduction in greenhouse gas emission if it is recycled. Also, the second comparison information is composed of information indicating the greenhouse gas emission amount of the recycled item and the reduction in greenhouse gas emission due to the use of the recycled item. However, the first comparison information and the second comparison information are not limited to such examples.

[0090] Fig. 8 is a schematic diagram showing an example of a product database 30A according to this modified example. In the example shown in Fig. 8, the product data has a recycled discharge amount field instead of the recycled reduction amount field shown in Fig. 4, and a virgin product discharge amount field instead of the recycled product reduction amount field.

[0091] The emission amount when recycled field stores information indicating the amount of greenhouse gas emission from the target item when the target item is recycled. The information stored in the emission amount field and the emission amount when recycled field is another example of the first comparison information. That is, in the example of Fig. 8, the first comparison information is composed of information indicating the amount of greenhouse gas emission from the target item when the target item is recycled and the amount of greenhouse gas emission from the target item when the target item is not recycled.

[0092] The virgin product emission amount field stores information indicating the greenhouse gas emissions of virgin products (i.e., when virgin products are used for components that are recycled products). The information stored in the emission amount field and the virgin product emission amount field is another example of the second comparison information. That is, in the example of FIG. 8, the second comparison information is composed of information indicating the greenhouse gas emissions of recycled products and the greenhouse gas emissions of virgin products.

[0093] Except for these points, the product database 30A according to this modification may be configured in the same manner as the product database 30 according to the above embodiment. In the above embodiment, the product database 30 may be replaced with the product database 30A according to this modification. As in the above embodiment, in step S101, the control unit 11 may receive a request 50 from the user terminal 2. In step S102, the control unit 11 may extract product information 55 of a product corresponding to the request 50 from the product database 30A. Then, in step S103, the control unit 11 may return the extracted product information 55 to the user terminal 2.

[0094] The user terminal 2 may output the first comparison information as appropriate. In one example, the first comparison information may be output in the format of FIG. 7 by displaying the value in the recycling emission amount field. In another example, the amount of greenhouse gas reduction resulting from recycling the target item may be calculated by subtracting the value in the recycling emission amount field from the value in the emission amount field. This calculation process may be executed by the information processing device 1, or may be executed by the user terminal 2. The calculated value of the reduction amount may be displayed, thereby outputting the first comparison information in the form of FIG.

[0095] In addition, the user terminal 2 may also output second comparison information as appropriate. In one example, the second comparison information may be output in the form of FIG. 7 by displaying the value in the virgin product emission amount field. In another example, the reduction amount due to the use of recycled products may be calculated by subtracting the value in the emission amount field from the value in the virgin product emission amount field. This calculation process may be executed by the information processing device 1, or may be executed by the user terminal 2. Then, the second comparison information may be output in the form of FIG. 6 by displaying the value of the calculated reduction amount.

[0096] In this modified example, the first comparison information can be used to visualize the contribution of recycling to reducing greenhouse gas emissions. Also, the second comparison information can be used to visualize the contribution of selecting products that include recycled items to reducing greenhouse gas emissions.

[0097] The configurations of the first comparison information and the second comparison information are not limited to the examples of FIG. 4 (embodiment) and FIG. 8 (variation), and may be appropriately determined according to the embodiment. In another example, either the first comparison information or the second comparison information may be configured in the form of FIG. 4, and the other may be configured in the form of FIG. 8. In yet another example, the first comparison information may be configured to indicate the increase in greenhouse gas emissions in the case where recycling is not performed, instead of the amount of greenhouse gas reduction in the case where recycling is performed. The second comparison information may be configured to indicate the increase in greenhouse gas emissions in the case where virgin products are included, instead of the amount of greenhouse gas reduction due to the inclusion of recycled products. The same applies to the output form.

[0098] <4.3> In the above embodiment, the packaging material may be omitted from each component of the product. In this case, each component of the present disclosure related to the packaging material may be omitted.

[0099] In the above embodiment, the recycling target item may be omitted from the attributes of each component of the product. In this case, each component of the present disclosure related to the recycling target item may be omitted. The first comparison information may be omitted from the product information.

[0100] In the above embodiment, the recycled goods may be omitted from the attributes of each component of the product. In this case, each component of the present disclosure related to the recycled goods may be omitted. The second comparison information may be omitted from the product information.

[0101] In the above embodiment, the flag information may be omitted from the discharge information. In this case, each component of the present disclosure related to the flag information may be omitted.

[0102] [5 Supplementary Note] The processes and means described in the present disclosure can be freely combined and implemented as long as no technical contradiction occurs.

[0103] Furthermore, a process described as being performed by one device may be shared and executed by multiple devices. Or, a process described as being performed by different devices may be executed by one device. In a computer system, the hardware configuration for implementing each function can be flexibly changed.

[0104] The present disclosure relates to a computer program that implements the functions described in the above embodiments. The present invention can also be realized by supplying the program to a computer, and having one or more processors of the computer read and execute the program. Such a computer program may be provided to the computer by a non-transitory computer-readable storage medium connectable to the system bus of the computer, or may be provided to the computer via a network. Non-transitory computer-readable storage media include, for example, any type of disk, such as a magnetic disk (e.g., a floppy disk, a hard disk drive (HDD), etc.), an optical disk (e.g., a CD-ROM, a DVD disk, a Blu-ray disk, etc.), a read-only memory (ROM), a random access memory (RAM), an EPROM, an EEPROM, a magnetic card, a flash memory, an optical card, and any type of medium suitable for storing electronic instructions.
