[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, conventional systems only provide information on greenhouse gas emissions in association with products, and although 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 from a product database product information of a product corresponding to the received request, the product information including emission information indicating the greenhouse gas emissions of the product in association with a production base of the product, and return the extracted product information to the user terminal so that the emission information can be output in association with the production base.

[0013] The information processing device according to the first aspect of the present disclosure provides information indicating the greenhouse gas emissions of the product in association with the production base. This allows the greenhouse gas emissions to be compared between the production bases of each product. In this comparison, since the greenhouse gas emissions of the target product are smaller than those of other products of the same type, it is possible to identify one of the factors that cause the target product to have low greenhouse gas emissions. In other words, it is possible to identify that being produced at the target production base 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] An embodiment according to one aspect of the present disclosure (hereinafter also referred to as "the present embodiment") will be described below 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, the data may be specified in pseudo-language, commands, parameters, machine language, etc. that can be recognized by a computer. do.

[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 the product in association with the production base of the product. The information processing device 1 returns the extracted product information to the user so that the emission information can be output in association with the production base. Outputting the emission information in association with the production base may be configured by outputting the greenhouse gas emission amount of the product in association with the production base.

[0017] As described above, according to this embodiment, it is possible to provide information (emission information) indicating the greenhouse gas emissions of a product in association with the production base where the product is produced. This makes it possible to compare the greenhouse gas emissions between the production bases of each product. In this comparison, if the greenhouse gas emissions of the target product are lower than those of other products of the same type, it is possible to identify that being produced at the target production base is one of the factors that reduces the greenhouse gas emissions of the target product. Therefore, according to this embodiment, it is possible to visualize at least some of the factors that reduce greenhouse gas emissions due to product selection behavior. As a result, it is possible to reduce the effort required for the user to confirm the factors.

[0018] (Product / Production base) 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 production base is a base where a product is produced. The production base of each product may be appropriately determined according to the embodiment. The production base may be, for example, various factories, kitchens, procurement sites, etc. A product may be produced at a single production base, or may be produced at multiple production bases. Producing a product at multiple production bases may include producing a product at each production base, as well as producing some components of the product and other components at different production bases. Note that 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 according to the embodiment. A component may be an item that can be grasped as a single unit. As an example, if a product is water sealed in a labeled PET bottle container, the components of the product may be water, a PET bottle container, and a label. The components of the product may include packaging materials.

[0020] In one example, outputting the emission information in association with the production base may be configured to output the greenhouse gas emission amount of the product at the single production base when the product is produced at a single production base, and may be configured to output the greenhouse gas emission amount of the product at each of the multiple production bases when the product is produced at multiple production bases. The type of the statistics is not particularly limited as long as it can express the characteristics of the greenhouse gas emission amount of the product at each of the multiple production bases, and may be appropriately selected depending on the embodiment. When a product is produced independently at each production base, the statistical amount may be, for example, an average value (simple average, weighted average), a maximum value, a minimum value, a percentile value, etc. When some components of a product and other components are produced at different production bases (i.e., one product is produced through multiple production bases), the statistical amount may be, for example, a total value, etc. An example of a case in which some components and other components are produced at different production bases is when the product is water sealed in a labeled PET bottle container, and the production of the PET bottle container and the procurement of the water are carried out at different bases.

[0021] As a typical example, when a product is produced independently at each production base and the number of products produced is equal at each production base, a simple average may be used as the statistical quantity. As another example, when there is a bias in the number of products produced at each production base, a weighted average according to the ratio of the number of products produced at each production base may be used as the statistical quantity. As yet another example, when components of a product are produced at different production bases, the total value of greenhouse gas emissions for the product (component) at each production base may be used as the statistical quantity. In this case, the greenhouse gas emissions for the product may include the greenhouse gas emissions when transporting the component between each production base. When the same component is produced at multiple production bases, the average value (simple average, weighted average) of greenhouse gas emissions for the product (component) at each production base may be used as the greenhouse gas emissions for the component.

[0022] However, the output format in the case where a product is produced at multiple production bases does not have to be limited to this example. In another example, in the case where a product is produced at multiple production bases, outputting the emission information in association with the production base may be configured by outputting the greenhouse gas emission amount of the product individually for each production base.

[0023] (request) The request 50 (query) includes conditions for searching for products. The search conditions may be specified by any method including known methods. As an example, the search conditions may be specified by a character string (e.g., product name, contents, etc.), a category, an attribute (e.g., price range, size, color scheme, material, brand, evaluation value, etc.), etc. The information processing device 1 is configured to refer to the product database 30 and extract product information 55 of products that meet the conditions specified in the request 50. The configuration of the product database 30 and the search method may employ any method including known methods.

[0024] (Greenhouse gases) As a typical example, the greenhouse gas is carbon dioxide. In addition, the greenhouse gas may include gases that bring about a greenhouse effect, such as methane, nitrous oxide, fluorocarbons, sulfur hexafluoride, and sulfur trifluoride. As shown in FIG. 1, in this embodiment, for convenience of explanation, carbon dioxide (CO2) is adopted as an example of a greenhouse gas. However, the greenhouse gas for which the emission amount is output is not limited to carbon dioxide, and may be appropriately selected depending on the embodiment. The greenhouse gas for which the emission amount is output may be composed of one or more types of gas. In one example, the greenhouse gas may be composed of carbon dioxide, methane, nitrous oxide, fluorocarbons, sulfur hexafluoride, sulfur trifluoride, or a combination thereof.

[0025] The greenhouse gas emissions of the products at the production site may be measured as appropriate depending on the embodiment. In one example, the greenhouse gas emissions of the products at the production site may be obtained by measuring the amount of greenhouse gases emitted during the process of producing the products, such as factory operation, cooking, procurement, etc.

[0026] (Product information) The product information stored in the product database 30 is not particularly limited in data format and structure as long as it includes emission information indicating the amount of greenhouse gas emissions associated with the production base. The item information may include information such as a description of the item, a price, and an image of the item, in addition to the ejection information.

[0027] 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 amount of greenhouse gas emissions associated with the production base, the data format and configuration are not particularly limited and may be appropriately determined depending on the embodiment.

[0028] (Renewable energy base) The production base of the product may include a first type base that uses renewable energy. The renewable energy used in the first type production base may not be particularly limited and may be appropriately selected depending on the embodiment. The renewable energy may be, for example, energy obtained from sunlight, wind power, hydroelectric power, geothermal heat, solar heat, atmospheric heat, other heat present in nature, biomass, etc.

[0029] In contrast, in this embodiment, a production base that does not use renewable energy is defined as a second type base. The second type base is a production base that does not use renewable energy (for example, does not use energy such as thermal power generation) and can produce the same products as the first type production base. The second type base may be virtually set in correspondence with the first type base.

[0030] When the production base of the product includes a first type base, the emission information of the product may include comparison information indicating a difference between the greenhouse gas emission amount of the product when the product is produced at the first type base and the greenhouse gas emission amount of the product when the product is produced at the second type base. Additionally, outputting the emission information may include outputting the comparison information.

[0031] This makes it possible to visualize the contribution to reducing greenhouse gas emissions by selecting products produced at production sites that use renewable energy. In addition, it makes it possible to visualize the effect of reducing greenhouse gas emissions by producing products at production sites that use renewable energy, depending on the characteristics of the energy supply in each region.

[0032] As an example, in regions with a lot of nuclear power generation, greenhouse gas emissions from power generation are relatively low, so the effect of reducing greenhouse gas emissions by producing goods at Type 1 bases is small. In contrast, in regions with a lot of thermal power generation, greenhouse gas emissions from power generation are relatively high, so the effect of reducing greenhouse gas emissions by producing goods at Type 1 bases is large. Therefore, by outputting comparative information, it is possible to visualize that greenhouse gas emissions can be significantly reduced by producing goods at Type 1 bases in regions with a lot of thermal power generation, compared to regions with a lot of nuclear power generation.

[0033] In addition, the data format of the comparison information is not particularly limited as long as it is possible to grasp the difference in greenhouse gas emissions when the product is produced at a first type site and when the product is produced at a second type site, and may be appropriately determined depending on the embodiment. In one example, the comparison information may be composed of information indicating the greenhouse gas emissions of the product and the reduction in greenhouse gas emissions due to the product being produced at the first type site instead of the second type site. In another example, the comparison information may be composed of information indicating the greenhouse gas emissions of the product and the greenhouse gas emissions of the product when the product is produced at the second type site.

[0034] The comparison information is output when the product is produced at the first type of facility and when the product is produced at the second type of facility. As long as it is possible to grasp the difference in greenhouse gas emissions when the product is produced at the first type site, the form of the information may not be particularly limited and may be appropriately determined depending on the embodiment. In one example, outputting the comparative information may be configured by outputting the greenhouse gas emissions of the product and the reduction in greenhouse gas emissions due to the product being produced at the first type site. In another example, outputting the comparative information may be configured by outputting the greenhouse gas emissions of the product when produced at the first type site and when produced at the second type site. When any of the above examples of the data format of the comparative information is adopted, any of the examples of the output form may be adopted.

[0035] (Greenhouse gas emissions from transportation) In general electronic commerce, purchased goods are transported to an address specified by the user. In response to this, in this embodiment, an estimate of greenhouse gas emissions during transportation from the production base to the address specified by the user may be calculated. Then, outputting the emission information in association with the production base may include outputting the estimated result of greenhouse gas emissions during transportation.

[0036] That is, in this embodiment, the product information 55 may further include information indicating the location of the production base. Then, outputting the emission information in association with the production base may include outputting the greenhouse gas emission amount in the transportation of the product from the production base to the address specified by the user, which is derived by the derivation rule associated with the product. This makes it possible to visualize the greenhouse gas emission amount in the transportation of the product from the production base to the address specified by the user.

[0037] The delivery destination address may be appropriately specified by the user. The user-specified address may be, for example, the user's own address or the address of the recipient to whom the product is to be given. The method of specifying the address is not particularly limited and may be appropriately selected depending on the embodiment. In one example, the delivery destination address may be specified by input on the user terminal 2. In another example, the user-specified address may be obtained from the user database 35.

[0038] One or more addresses that the user may specify may be registered in advance in the user database 35 in association with the user. That is, the user database 35 may hold address information in association with the user's identification information. The address specified by the user may be selected from one or more addresses registered in the user database 35 in association with the user's identification information.

[0039] The route of transportation may be determined appropriately depending on the embodiment. In one example, the product may be transported directly from the production base to the user-specified address. In another example, the product may be transported from the production base to the user-specified address via one or more intermediate points. The intermediate points may be, for example, storage locations (warehouses, etc.).

[0040] The greenhouse gas emissions in transportation are the amount of greenhouse gases emitted by the transportation of a commodity. The commodity may be transported by any means. The means of transporting the commodity may be, for example, a transport vehicle (such as a truck), a train, an airplane, a drone, etc. In one example, the greenhouse gas emissions in transportation may be estimated from the energy consumed in transportation by a specific transport means according to the commodity.

[0041] As long as the derivation rule is associated with a product, the storage destination and data format of the derivation rule are not particularly limited and may be appropriately determined depending on the embodiment. In one example, the derivation rule may be stored in the product database 30 together with the product information. In another example, the derivation rule may be stored in a storage area different from the product database 30.

[0042] The derivation rule may be appropriately specified for each product so that the greenhouse gas emissions during transportation can be calculated. As an example, the derivation rule may be composed of a calculation formula of "ax+b". x indicates the transportation distance, and a and b indicate constants. The values ​​of a and b may be arbitrarily specified. The value of a may be determined, for example, according to the transportation means, the energy used in the transportation means, etc. The value of b may be determined, for example, according to the greenhouse gas emissions during transportation from the production base to the warehouse, etc.

[0043] In one example, when this derivation rule is adopted, a transportation route from a production base to a specified address may be searched for on a map. Any map search method, including known methods, may be adopted to search for the transportation route. When the product is stored in a warehouse away from the production base, a transportation route from the warehouse to the specified address may be searched for. Then, the transportation distance may be calculated from the searched route. The calculated transportation distance value may be substituted into the above formula, and the calculation of the formula may be performed to derive the greenhouse gas emissions in transportation to the user-specified address.

[0044] In a typical example, the process of deriving the emission amount according to the derivation rule may be executed by the information processing device 1. However, the present embodiment is not limited to such an example. In another example, information indicating the derivation rule may be provided to the user terminal 2 together with the product information. As a result, the process of deriving the emission amount according to the derivation rule may be executed by the user terminal 2.

[0045] In addition, in this embodiment, outputting the discharge information in association with the production base may further include outputting an outline of the location of the production base. The outline of the location is information indicating the general location of the location obtained by partially omitting the location (address). The range of the location output as an outline may be appropriately determined depending on the embodiment so that the general location of the location can be grasped. As an example, outputting an outline of the location may be omitting a smaller division (e.g., a street address) out of multiple divisions constituting the location (address) and outputting part of the location (e.g., up to the prefecture name).

[0046] In addition, in this embodiment, outputting the emission information in association with the production base may further include outputting information indicating whether the production base is located in Japan or overseas. Hereinafter, for convenience of explanation, information indicating whether the production base is located in Japan or overseas will also be referred to as "location country information". Note that whether the production base is located in Japan or overseas may be determined based on any criteria. In one example, whether the production base is located in Japan or overseas may be determined based on the main region where the information processing device 1 provides product information. In this case, whether the production base of each product is located in Japan or overseas may be determined in advance. In another example, whether the production base is located in Japan or overseas may be determined based on the location of the user of the user terminal 2 (for example, an address specified by the user, an access location of the user terminal 2, etc.).

[0047] The form of the output of the country of location information is not particularly limited as long as it is possible to determine whether the production base of the target product is located domestically or overseas, and may be determined appropriately depending on the embodiment. In one example, outputting the country of location information may be configured by outputting a character string indicating whether the product is produced domestically or overseas (e.g., "Produced domestically", "Produced overseas", etc.). In another example, outputting the country of location information may be configured by outputting an arbitrary indicator indicating whether the product is produced domestically or overseas. In yet another example, outputting the country of location information may be configured by outputting the location (address) of the production base in a state in which the name of the country in which the production base is located can be identified.

[0048] By outputting at least one of the outline of the location of the production base and the country, it is possible to visualize the greenhouse gas emissions in transportation in association with the location of the production base. This makes it possible to visualize the efforts of product providers to reduce greenhouse gas emissions in transportation. For example, if a production base is located far away (overseas) but greenhouse gas emissions during transportation are low, it becomes clear that the efforts of the product provider have reduced greenhouse gas emissions during transportation.

[0049] For comparison, the amount of greenhouse gas emissions in the transportation of other products produced at other production bases located at the same or nearby production base of the target product may be output. That is, outputting the emission information in association with the production base may include outputting the amount of greenhouse gas emissions in the transportation of other products produced at other production bases located at the same or nearby production base of the target product, in addition to the amount of greenhouse gas emissions in the transportation of the above product.

[0050] In one example, the amount of greenhouse gas emissions in the transportation of the other goods may be derived from the product information of the other goods registered in the product database 30 in a manner similar to that described above. When there are a plurality of other goods, the amount of greenhouse gas emissions in the transportation of the other goods may be expressed by a statistical quantity such as an average value, a maximum value, or a percentile value. In another example, the amount of greenhouse gas emissions in the transportation of the other goods may be expressed by a standard value of greenhouse gas emissions in normal transportation. The standard value of the emission amount may be calculated as appropriate assuming a general means of transportation. Furthermore, the standard value of the emission amount may be managed as appropriate in association with the goods. As an example of management, the standard value of the emission amount may be stored in the product database 30 together with the product information. In this case, the standard value of the emission amount may be obtained from the product database 30.

[0051] The same or nearby range may be appropriately determined depending on the embodiment. In one example, the same or nearby range may be appropriately set as a range in which a production base of a target product and a production base of another product are in the same city, in the same town, etc., and therefore the greenhouse gas emissions are similar if the production base is the same means of transportation.

[0052] (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.

[0053] 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.

[0054] [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 information processing device 1 may acquire at least one of the program 81, product database 30, and user database 35 from the storage medium 91.

[0061] 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.

[0062] 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.

[0063] 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 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.

[0065] [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).

[0066] 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 from the product database 30, the product information 55 including emission information indicating the greenhouse gas emission amount of the product in association with a production base of the product. 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 in association with the production base.

[0067] 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.

[0068] (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 on two products. The product data has fields for storing the product name, production base, emission amount, base flag, reduction amount, location, overseas flag, and derivation rule.

[0069] The product name field stores information indicating the name of the product. The production base field stores information indicating the name of the production base. The emission amount field stores information indicating the greenhouse gas emission amount of the target product at the target production base.

[0070] The base flag field stores information (flag) indicating whether the target production base is a first type base that uses renewable energy. In the example of FIG. 4, "1" indicates that the target production base is a first type base, and "0" indicates that the target production base is a second type base that does not use renewable energy. The reduction amount field stores information indicating the amount of reduction in greenhouse gas emissions due to the product being produced at a first type base rather than a second type base.

[0071] The location field stores information indicating the location of the production base. The overseas flag field stores information (flag) indicating whether the production base is located in Japan or overseas. In the example of FIG. "0" indicates that the production base is located domestically, and "1" indicates that the production base is located overseas.

[0072] In the example of Fig. 4, for the fields after the production base, records (row data) are provided for each production base. Various information about each production base is stored in each record. The information stored in each field from the emission amount to the overseas flag is an example of emission information.

[0073] The information stored in the emission amount field and the reduction amount field is an example of the comparison information. That is, in the example of Fig. 4, the comparison information is composed of information indicating the greenhouse gas emission amount of the product and the reduction amount of the greenhouse gas emission due to the product being produced at the first type site instead of the second type site.

[0074] The information stored in the location field is an example of information indicating the location of a production base. The information stored in the overseas flag field is an example of information indicating whether the production base is located domestically or overseas. If the location information stored in the location field includes a country name or information that can identify a country name, it is possible to determine whether the production base is located domestically or overseas from the location information. Therefore, the information stored in the location field may be treated as an example of information indicating whether the production base is located domestically or overseas. When determining the country in which the production base is located from the location information, the overseas flag field may be omitted.

[0075] In the example of FIG. 4, the following conditions are assumed as specific examples of products. That is, the product "Water A" is produced at two production bases (base A, base B), and the product "Water C" is produced at a single production base (base C). Of the two production bases that produce "Water A", base A is a second type base, and base B is a first type base. Base C that produces "Water C" is a second type base. The two production bases (base A, base B) that produce "Water A" are located domestically, and base C that produces "Water C" is located overseas. A derivation rule is given for each production base of the product. However, these conditions are merely specific examples for the convenience of explanation, and do not limit the contents of this disclosure.

[0076] 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 the like. This information may also be stored in the product data of the product database 30.

[0077] In the example of FIG. 4, for the base flag and the overseas flag, the flag is expressed by "1" and the flag is expressed by "0". However, the expression format of the flag is not limited to such an example and may be appropriately determined depending on the embodiment. In addition, the expression of various information of each product is not limited to the example of FIG. 4 and may be appropriately determined depending on the embodiment.

[0078] (user database) Fig. 5 is a schematic diagram of an example of the user database 35 according to the present embodiment. In the example shown in Fig. 5, one record (row data) corresponds to user information for one user. The record shown in Fig. 5 has fields for storing a user ID (identification information) and a registered address.

[0079] The user ID field stores information (identifier, identification information) for identifying the user. The registered address field stores addresses that may be designated as the shipping destination of the product. Each record may have one or more address fields to hold one or more addresses for a user. User information may be registered or updated in user database 35 at any time, including known times such as when a user's account is created or modified.

[0080] The data format of user database 35 need not be limited to the example shown in FIG. 5. As long as user database 35 stores user information in a searchable state, the data format need not be particularly limited and may be determined appropriately depending on the embodiment. Furthermore, the user information stored in user database 35 may include information other than the information shown in FIG. 5. The user information may include, for example, a password, payment information (e.g., a credit number), other user attributes, and the like. Each record of user database 35 may also store such information.

[0081] [3 Example of operation] 6 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.

[0082] (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.

[0083] Any method, including known methods, may be adopted for inputting product search conditions in the user terminal 2 and for transmitting the request 50 from the user terminal 2 to the information processing device 1. In one example, the user terminal 2 may accept the specification of search conditions via an input device. The search conditions may be specified by, for example, a character string, a category, an attribute, etc. The user terminal 2 may transmit the request 50 including the specified 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 proceeds to the next step S102.

[0084] (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.

[0085] 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.

[0086] (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 the discharge information can be output in association with the production base. In response to this, 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.

[0087] 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.

[0088] Fig. 7 shows a schematic example of an output form (screen display) of product information 55 in a user terminal 2 according to this embodiment. The example in Fig. 7 assumes a scene in which product information 55 for "Water A" and "Water C" 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).

[0089] In this example of the screen display, the value of the emission amount field is displayed in area 200 in association with the value of the production base field, thereby outputting the greenhouse gas emission amount in association with the production base. When a product ("Water A") is produced at multiple production bases, statistics on the greenhouse gas emission amount at each production base may be output. In the example of FIG. 7, a simple average is used as an example of the statistics. When a product ("Water C") is produced at a single production base, the greenhouse gas emission amount at the single production base may be output.

[0090] When a product is produced at multiple production bases, the statistics of greenhouse gas emissions at each production base may be calculated by the information processing device 1 or the user terminal 2 when outputting the product information 55. Alternatively, the statistics may be calculated in advance, and the calculated statistics may be stored in the product database 30. In this case, the statistics of greenhouse gas emissions at each production base can be output by displaying the value of the corresponding field of the corresponding record.

[0091] The amount of greenhouse gas emissions reduction due to production at a first type base is output by displaying the value of the reduction amount field of the product information 55 in the speech bubble 210. In the example of Fig. 7, the production bases that produce "Water A" include a first type base (base B), so the speech bubble 210 is displayed corresponding to "Water A" and the amount of reduction by the first type base is output.

[0092] When the product is produced at a single first type site, the reduction amount by the first type site may be output as it is. On the other hand, when the product is produced at multiple production sites, the reduction amount statistics may be output in the balloon 210 in response to the output of the emission amount statistics in the area 200. In the example of FIG. 7, a simple average is also used as an example of the reduction amount statistics in response to the display of the emission amount. However, the output method of the reduction amount when the product is produced at multiple production sites may not be limited to this example. In another example, the reduction amount by the first type site may be output as it is. When the product is produced at multiple first type sites, the reduction amount by each first type site may be output individually. In yet another example, when the multiple production sites that produce the product include multiple first type sites, the reduction amount statistics only for the first type site may be output.

[0093] The output of information in the area 200 and the balloon 210 is an example of the output of proportional information. It is possible to visualize the contribution to the reduction of greenhouse gas emissions by selecting products produced at production sites that have the same carbon dioxide emissions. The reduction amount may be expressed in another form, such as the area of ​​forest that absorbs the carbon dioxide of the reduction amount.

[0094] The amount of greenhouse gas emissions in transportation is output in an area 220. The amount of emissions in transportation may be calculated appropriately from the information in the location field, the information in the derivation rule field, and the address specified by the user.

[0095] As an example, when the information processing device 1 calculates the amount of greenhouse gas emissions during transportation, the control unit 11 may acquire a derivation rule from a derivation rule field in the product information 55 of the target product. The control unit 11 may acquire the location of the production base from a location field. In the following, for convenience of explanation, it is assumed that the derivation rule is defined so that the amount of greenhouse gas emissions during transportation can be calculated according to the transportation distance, as in the example of the derivation rule described above and FIG. 4.

[0096] The control unit 11 may acquire the user-specified address by any method. In one example, the control unit 11 may acquire the user-specified address from the user terminal 2. In another example, the control unit 11 may acquire the user-specified address from the user database 35.

[0097] For example, the control unit 11 may request user authentication by logging in when accessing from the user terminal 2. The user authentication may be performed by any method including a known method. For example, the user database 35 may further store a password in association with the user's identification information, and the control unit 11 may authenticate the user by matching the password. In response to this user authentication, the control unit 11 may recognize the user of the user terminal 2 from which the access originates and obtain the user's identification information. The control unit 11 may refer to the user database 35 and match the value of the user ID field with the obtained identification information to extract address information associated with the identification information from the user database 35. The control unit 11 may obtain the address specified by the user from the extracted address information. When multiple addresses are registered, the control unit 11 may accept, from the user terminal 2, a selection of an address to be mailed from the multiple registered addresses.

[0098] The control unit 11 may search for a transportation route from the location of the production base to the specified address on the map, and may acquire the transportation distance to the user-specified address based on the search result. The control unit 11 may then substitute the acquired transportation distance value into the derivation rule and execute the arithmetic processing of the derivation rule to derive the greenhouse gas emission amount in the transportation to the user-specified address. When the product is produced at multiple production bases, the control unit 11 may derive the greenhouse gas emission amount in the transportation from each production base to the user-specified address. In one example, the control unit 11 may transmit the derived emission amount to the user terminal 2 and cause the derived emission amount statistics to be output in the area 220. In another example, the control unit 11 may transmit the derived emission amount to the user terminal 2 and cause the user terminal 2 to output the greenhouse gas emission amount in the transportation for each production base individually in the area 220.

[0099] Note that the computer that executes the process of deriving the emission amount according to the derivation rules is not limited to the information processing device 1. In another example, the control unit 11 may provide the values ​​of the location field and the derivation rule field to the user terminal 2 as product information 55, and cause the user terminal 2 to execute the process of deriving the greenhouse gas emission amount during transportation. The output of information in the area 220 is an example of outputting the greenhouse gas emission amount during transportation. The output of the area 220 makes it possible to visualize the greenhouse gas emission amount during the transportation of the product from the production base to the address specified by the user.

[0100] In area 230, information corresponding to the overseas flag field is displayed to indicate the production Information indicating whether the base is located domestically or overseas is output. The output of information in the area 230 is an example of outputting information indicating whether the production base is located domestically or overseas.

[0101] In the example of Figure 7, the value of the overseas flag field of "Water A" is "0", so that "Made in Japan" is displayed in area 230 of "Water A". On the other hand, the value of the overseas flag field of "Water C" is "1", so that "Made overseas" is displayed in area 230 of "Water C". The information to be output to area 230 may be specified based on the value of the location field, rather than the value of the overseas flag field.

[0102] In area 240, a part of the value in the location field is displayed, thereby outputting an outline of the location of the production base. Outputting information in area 240 is an example of outputting an outline of the location of the production base. By including at least one of area 230 and area 240 in the screen display, it is possible to visualize greenhouse gas emissions in transportation in association with the location of the production base.

[0103] Fig. 8 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. 8, the speech bubble 210 outputting comparison information is replaced with a speech bubble 215 employing a different output form. Except for this point, the screen shown in Fig. 8 is configured in the same way as Fig. 7.

[0104] The greenhouse gas emission amount of the target product when produced at the second type site is output in the balloon 215. The greenhouse gas emission amount at the second type site may be calculated by adding the value in the reduction amount field to the value in the emission amount field. This calculation process may be executed by the information processing device 1 or the user terminal 2.

[0105] Similarly to the output form of the reduction amount, when a product is produced at a plurality of production bases, the greenhouse gas emission statistics at the second type base may be output in the balloon 215 in response to the emission statistics being output in the area 200. When some of the plurality of production bases are the first type bases and the rest are the second type bases, the value in the emission amount field may be used as is for the second type bases. For the first type bases, the virtual emission amount when the product is produced at the second type base may be calculated by the above-mentioned addition process. Then, the emission statistics to be displayed in the balloon 215 may be calculated from the obtained emission amount values ​​at each base. However, the method of outputting the emission amount at the second type base when the product is produced at a plurality of production bases may not be limited to this example. In another example, when a product is produced at a plurality of first type bases, the emission amounts at the second type bases calculated by the above-mentioned addition process may be output individually.

[0106] Meanwhile, in area 200, greenhouse gas emissions for at least some of the products when produced at a first type site are output. The output of information in area 200 and speech bubble 215 is another example of output of comparative information. By outputting information in area 200 and speech bubble 215, it is possible to visualize the contribution to reducing greenhouse gas emissions by selecting products produced at production sites that use renewable energy.

[0107] The output of information shown in Figures 7 and 8 is an example of outputting discharge information in association with a production base. However, the output form shown in Figures 7 and 8 is merely an example for convenience of explanation, and the output form of the product information 55 (screen design, order of voice output, etc.) does not have to be limited to such an example.

[0108] When the product information 55 includes comparison information, the comparison information is The comparison information may be output by, for example, placing the cursor over area 200 on screen 8, or may be output without a user instruction. The same applies to other information. The form in which the comparison information is output is not limited to a speech bubble, and may be appropriately selected depending on the embodiment. In any area in which product information 55 is output, it may be displayed whether the target product is produced at a production base that uses renewable energy.

[0109] 7 and 8, as an example of the output form of the country information in area 230, output of a character string indicating whether the product is produced domestically or overseas is adopted. The output form of the country information need not be limited to this example. In another example, the country information may be indicated by any sign. In yet another example, the location (address) of the production base may be output as the country information in a state in which the name of the country in which the production base is located can be specified. When an outline of the location is output in area 240 in a state in which the country name can be specified, area 230 may be omitted, and the output of the information in area 240 may also serve as the output of the country information.

[0110] 7 and 8, as an example of an output form of the outline of the location in the area 240, when the production base is located domestically, only the prefecture name is output as the outline of the location, and when the production base is located overseas, the country name and prefecture name are output as the outline of the location. However, the output form of the outline of the location does not need to be limited to such an example. The range to be displayed as the outline of the location may be appropriately determined depending on the embodiment.

[0111] 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.

[0112] [Features] The information processing device 1 according to the present embodiment can provide product information 55 including emission information indicating the amount of greenhouse gas emission associated with the production base of the product by the processing of steps S101 to S103. This allows comparison of greenhouse gas emission between the production bases of each product based on the provided information (examples of which are shown in Figs. 7 and 8). In this comparison, if the greenhouse gas emission of the target product is less than that of other products of the same type, it can be determined that the product is produced at the target production base as one of the factors of the reduction in greenhouse gas emission of the target product. Therefore, according to the present embodiment, at least a part of the factors of the reduction in greenhouse gas emission due to the selection behavior of the product can be visualized. As a result, the effort required for the user to confirm the factors can be reduced.

[0113] [4 Variations] Although the embodiment of the present disclosure has been described in detail above, 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 the same components as in the above embodiment, and the description of the same points as in the above embodiment is omitted as appropriate. The following modifications can be combined as appropriate.

[0114] <4.1> In the above embodiment, the greenhouse gas emission amount may be output for each component of the product. In addition, in the above embodiment, when the product is produced at a plurality of production bases, the product may be One or more production bases (hereinafter also referred to as "providing bases") to be provided to the user may be selected from among the multiple production bases. The selection method may be determined arbitrarily. In one example, the providing base may be specified by the user via the user terminal 2. In another example, any number of production bases close to an address specified by the user (e.g., the production base closest to the specified address) may be selected from among the multiple production bases. In this case, the greenhouse gas emissions of the product may be output for the selected one or more production bases.

[0115] <4.2> In the above embodiment, the derivation rules are stored in the product database 30. However, the storage destination of the derivation rules may not be limited to this example. The derivation rules may be stored in a storage area other than the product database 30. In addition, in the above embodiment, the derivation rules are set for each production base. However, the method of setting the derivation rules may not be limited to this example. For example, there are cases where the transportation routes from each production base are at least partially common, such as when products produced at each of multiple production bases are stored in a common storage location and provided to users. In such a case, at least a part of the derivation rules may be shared between the production bases. That is, at least a part of the derivation rules may be set in common at multiple production bases.

[0116] <4.3> In the above embodiment, the product database 30 and the user database 35 are stored in a storage device (storage unit 12, external storage device, storage medium 91, etc.) of the information processing device 1. However, the storage destination of each database (30, 35) may not be limited to such an example. In another example, at least one of the product database 30 and the user database 35 may be stored in another computer such as a network server. The product database 30 and the user database 35 may be stored in different devices. When the product database 30 is stored in another computer, 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). Similarly, when the user database 35 is stored in another computer, the control unit 11 may acquire the user information including the registered address from the user database 35 by connecting to the other computer via a network or the like.

[0117] <4.4> 4 of the above embodiment, the comparison information is composed of information indicating the greenhouse gas emission amount of the product and the reduction in greenhouse gas emission due to the product being produced at the first type site. However, the composition of the comparison information is not limited to this example.

[0118] Fig. 9 shows an example of a product database 30A according to this modification. In the example shown in Fig. 9, the product data has a second type base emission field instead of the reduction amount field shown in Fig. 4. Except for this point, the product database 30A according to this modification may be configured in the same way as the product database 30 according to the above embodiment.

[0119] The second type facility emission amount field stores information indicating the greenhouse gas emissions of a product that would have been generated if the product was produced at a second type facility, for a product produced at a first type facility. The information stored in the emission amount field and the second type facility emission amount field is another example of the comparison information. That is, in the example of FIG. 9, the comparison information is composed of information indicating the greenhouse gas emissions of the product and the greenhouse gas emissions of the product if the product were produced at a second type facility.

[0120] In the above embodiment, the product database 30 may be replaced with the product database 30A according to this modified example. 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.

[0121] The user terminal 2 may output the comparative information as appropriate. In one example, the comparative information may be output in the form of FIG. 8 by displaying the value in the second type base emission amount field. In another example, the amount of reduction in greenhouse gas emissions due to production at the first type base may be calculated by subtracting the value in the emission amount field from the value in the second type base 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 calculated value of the reduction amount may be displayed to output the comparative information in the form of FIG. 7. In the case where a product is produced at multiple production bases, the same procedure as in the above embodiment may be followed.

[0122] This modified example also makes it possible to visualize the contribution to reducing greenhouse gas emissions by selecting products produced at production bases that use renewable energy, using the comparison information. The configuration of the comparison information is not limited to the examples shown in Figures 4 (embodiment) and 9, and may be determined appropriately depending on the embodiment. In another example, the comparison information may be configured to show the increase in greenhouse gas emissions when the product is produced at a second type site, instead of the reduction in greenhouse gas emissions caused by production at a first type site. The same applies to the output format.

[0123] <4.5> In the above embodiment, it is not necessary to determine whether the production site uses renewable energy. In this case, the components of the present disclosure related to the production site using renewable energy may be omitted.

[0124] In the above embodiment, the amount of greenhouse gas emissions in the transportation may not be output. In this case, the components of the present disclosure related to outputting the amount of greenhouse gas emissions in the transportation may be omitted.

[0125] [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.

[0126] 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.

[0127] The present disclosure can also be realized by supplying a computer program implementing the functions described in the above embodiments to a computer, and having one or more processors of the computer read and execute the program.
