[0014] Hereinafter, with reference to the drawings, embodiments of a delivery assistance system, a delivery assistance method, a program, and a non-transitory recording medium for recording the program according to the present disclosure will be described in detail. The disclosed technology is not limited to these embodiments. In this embodiment, carbon dioxide is used as an example, but other substances that may have an impact on the environment may also be used. For example, other substances include, but are not limited to, greenhouse gases other than carbon dioxide, such as methane and nitrous oxide.

[0015] In the following explanation, carbon dioxide may be referred to as CO2. In the following explanation, the amount of carbon dioxide emitted may be abbreviated to "emissions," and the amount of carbon dioxide reduction may be abbreviated to "reduction amount."

[0016] (Embodiment 1) First, in the embodiment 1, a basic function of a delivery support system will be described. Fig. 1 is a block diagram showing an example of the configuration of the delivery support system according to the embodiment 1. The delivery support system 10 supports the reduction of carbon dioxide emissions through joint deliveries.

[0017] The delivery support system 10 includes an emission amount calculation unit 101, a reduction amount calculation unit 102, and an output control means.

[0018] In joint delivery, the emission calculation unit 101 calculates the amount of carbon dioxide emissions for each of the current delivery method and another delivery method different from the current delivery method. The current delivery method is a predetermined delivery method. The other delivery method is a predetermined delivery method that can be provided by a logistics company. Furthermore, the other delivery method may be, for example, a delivery method designated by the shipper from multiple delivery methods predetermined by the logistics company. The current delivery method and the other delivery method are not particularly limited, for example, to vehicles, ships, airplanes, drones, etc. Furthermore, the vehicles are not particularly limited to trucks, bicycles, etc. Joint delivery means that multiple shippers load their cargoes onto the same delivery method, such as the same truck, for delivery. Furthermore, the period for which the emission calculation unit 101 calculates the amount of carbon dioxide emissions is not particularly limited, and may be one time, multiple times, monthly, or annually.

[0019] Furthermore, the method for calculating carbon dioxide emissions is not particularly limited, and any existing technology may be used, such as the ton-kilometer method, which uses the weight of the cargo multiplied by the transport distance, the fuel consumption method, which uses the transport distance and fuel efficiency, or the like.

[0020] The reduction amount calculation unit 102 calculates the amount of carbon dioxide reduction that would occur if the current delivery method were switched to another delivery method, based on the calculated emissions for each of the current delivery method and the other delivery method. For example, the reduction amount calculation unit 102 calculates the amount of carbon dioxide reduction by subtracting the amount of carbon dioxide emission that would occur if the current delivery method were switched to the other delivery method from the amount of carbon dioxide emission for the current delivery method. The reduction amount may also be expressed as a percentage of the reduction in carbon dioxide emission. In the following description, the reduction amount will be expressed as this percentage. Therefore, for example, the reduction amount calculation unit 102 may calculate the amount of carbon dioxide reduction as the ratio of the subtracted value to the amount of carbon dioxide emission for the current delivery method.

[0021] The output control unit 103 presents the calculated reduction amount. For example, the output control unit 103 presents the reduction amount to a specific shipper. The method by which the output control unit 103 presents the reduction amount to a specific shipper is not particularly limited. For example, as a method of presenting the reduction amount, the output control unit 103 may notify the shipper of the reduction amount using an electronic message, email, or the like. Alternatively, as a method of presenting the reduction amount, the output control unit 103 may output the reduction amount to a terminal device of the shipper. Specifically, for example, the output control unit 103 may display the reduction amount on a display device of a terminal device of the specific shipper. Alternatively, the output control unit 103 may output the reduction amount as an audio output from an audio output device of the terminal device of the shipper.

[0022] Furthermore, for example, when switching from a current delivery method to another delivery method, carbon dioxide emissions may be reduced or increased. Therefore, the output control unit 103 may present the reduction amount according to the reduction amount. Specifically, for example, the output control unit 103 may present the reduction amount when the reduction amount is equal to or greater than a predetermined value. This makes it possible to present to the shipper delivery methods that can reduce carbon dioxide emissions more than the current delivery method.

[0023] 2 is a flowchart showing an example of an operation of the delivery support system 10 according to the embodiment 1. The emission amount calculation unit 101 calculates the amount of carbon dioxide emission for each of the current delivery method and another delivery method (step S101).

[0024] The reduction amount calculation unit 102 calculates the amount of carbon dioxide reduction when switching from the current delivery method to another delivery method based on the calculated emissions for each of the current delivery method and the other delivery method (step S102). The output control unit 103 presents the calculated reduction amount (step S103). The delivery support system 10 ends the processing.

[0025] As described above, in the first embodiment, the delivery support system 10 calculates and presents the amount of carbon dioxide reduction that would occur if the current delivery method were switched to another delivery method. In this way, a platform that can present environmentally friendly delivery options can be provided. Such a platform may be provided to companies that cannot prepare their own platforms, such as small and medium-sized enterprises and e-commerce (electronic commerce) companies. This allows users to select an environmentally friendly delivery method. Therefore, it is possible to promote the use of environmentally friendly delivery methods.

[0026] By providing such a platform, it is possible to reduce carbon dioxide emissions. Also, by informing shippers that the joint delivery is environmentally friendly, it is possible to prevent shippers who want to be environmentally conscious from withdrawing from the joint delivery. Furthermore, by diversifying delivery methods, it is possible to alleviate traffic congestion.

[0027] (Embodiment 2) Next, a second embodiment will be described in detail with reference to the drawings. In the second embodiment, a specific example of presenting the amount of carbon dioxide reduction will be described. Below, the description of the second embodiment will be omitted to the extent that it does not make the description of the second embodiment unclear.

[0028] FIG. 3 is an explanatory diagram showing an example of joint delivery. For example, in FIG. 3, a logistics company collects and delivers packages from multiple shippers at a joint delivery center. In the example of FIG. 3, the shippers are shipper A, shipper B, and shipper C, and the logistics company loads the packages collected and delivered from each of the multiple shippers onto the same truck for delivery. This delivery is joint delivery. The truck then delivers each package to the destination of each shipper's package. Here, the destination of each shipper's package may be the same. Furthermore, the destination is not limited to a specific destination, and may be a direction toward the destination, etc. Furthermore, the destination here is not limited to a final destination, and may be a stopover along the way.

[0029] The joint delivery in FIG. 3 is just one example, and other joint delivery methods such as a milk run system in which one truck collects and delivers from multiple companies may also be used.

[0030] 4 is an explanatory diagram showing an example of a connection between the delivery support system and other devices. For example, the delivery support system 20 is connected to each shipper's terminal device 21 and the like via a communication network NT. In FIG. 4, one communication network NT is shown as an example for ease of explanation, but the delivery support system 20 may be connected to each device via a different communication network NT, and is not particularly limited.

[0031] 4 shows the consignor's terminal device 21-1 and terminal device 21-2, but the consignor's terminal device 21 may be for each consignor, and the number of consignor's terminal devices 21 is not particularly limited. When the consignor's terminal device 21 is not uniquely identified, it is simply referred to as the terminal device 21. The type of the consignor's terminal device 21 is not particularly limited, and may be a smartphone, a tablet device, or a PC (Personal Computer).

[0032] 5 is a block diagram showing an example of a configuration of a delivery support system 20 according to the second embodiment. The delivery support system 20 includes an emission amount calculation unit 201, a reduction amount calculation unit 202, an output control unit 203, a reception unit 204, an identification unit 205, and an acquisition unit 206. The delivery support system 20 according to the second embodiment further includes the reception unit 204, the identification unit 205, and the acquisition unit 206 in addition to the components of the delivery support system 10 according to the first embodiment. The emission amount calculation unit 201 has the function of the emission amount calculation unit 101 according to the first embodiment as a basic function. The reduction amount calculation unit 202 has the function of the reduction amount calculation unit 102 according to the first embodiment as a basic function. The output control unit 203 has the function of the output control unit 103 according to the first embodiment as a basic function.

[0033] The delivery support system 20 includes a parcel DB 2001 and a shipper DB 2002 .

[0034] The luggage DB 2001 stores information about luggage for each luggage. For example, the luggage DB 2001 stores luggage identification information for identifying a luggage, a luggage destination, a luggage quantity, and shipper identification information for identifying a shipper of the luggage, in association with each other. The luggage identification information for identifying a luggage is not particularly limited as long as it can uniquely identify the luggage. The shipper identification information for identifying a shipper is not particularly limited as long as it can uniquely identify the shipper. The destination of a luggage is not limited to a specific destination and may be a direction of the destination. Furthermore, the destination here is not limited to a final destination and may be a stopover point along the way. The type of luggage quantity may vary depending on the characteristics of the luggage, and is not particularly limited to the spatial quantity of the luggage, the weight quantity of the luggage, or a combination thereof. For example, a weight quantity is used for the quantity of luggage such as steel materials. When the quantity of luggage is the spatial quantity of the luggage, the unit of the luggage quantity is not particularly limited, and may be an existing unit such as volume or the number of pieces in a specific package. Furthermore, when the amount of luggage is the weight of the luggage, the unit of the luggage amount is not particularly limited and may be an existing unit such as weight.

[0035] The shipper DB 2002 stores information about the shipper for each shipper. The information about the shipper includes at least one of the shipper's name, the shipper's industry, and information about the shipper's environmental activities. For example, the shipper DB 2002 stores shipper identification information that identifies the shipper in association with information about the shipper. The shipper identification information that identifies the shipper is not particularly limited as long as it can uniquely identify the shipper.

[0036] The information on environmental activities by the shipper is not particularly limited. The information on environmental activities may be, for example, the goals of the shipper's environmental activities. The information on environmental activities may also be the type of electricity used by the shipper. If the shipper generates electricity, the information on environmental activities may also be the type of electricity generated by the shipper. The information on environmental activities may also be the type of electricity that the shipper declares not to use. If the shipper generates electricity, the information on environmental activities may also be the amount of carbon dioxide emitted during power generation. The information on environmental activities may also be the amount of carbon dioxide emitted in the shipper's business activities.

[0037] Next, each functional unit will be described.

[0038] Here, the information used to calculate the carbon dioxide emission amount, such as the quantity of parcels, the parcel shipper, the planned delivery route, the planned transport distance, and the planned amount of fuel used for the current delivery method in joint delivery, as a premise for the reduction amount calculation unit 202 to calculate the carbon dioxide emission amount, may be derived by the parcel DB 2001 using existing technology. Therefore, this information may be stored in advance in a database or the like as information related to the current delivery method. Similarly, information used to calculate the carbon dioxide emission amount, such as the quantity of parcels, the parcel shipper, the delivery route, the transport distance, and the planned amount of fuel used for other delivery methods, may be derived by the parcel DB 2001 using existing technology. Furthermore, the delivery fee for other delivery methods may also be derived using existing technology. Therefore, this information may be stored in advance in a database or the like as information related to other delivery methods.

[0039] As explained in the first embodiment, the period for which the emission calculation unit 201 calculates the carbon dioxide emission amount is not particularly limited, and may be once, multiple times, monthly, yearly, etc. Therefore, the acquisition unit 206 only needs to acquire information on the current delivery method and information on other delivery methods according to the period to be calculated.

[0040] Next, the emission amount calculation unit 201 calculates the carbon dioxide emission amount for each of the current delivery method and the other delivery methods in the joint delivery. As described in the first embodiment, the method for calculating the carbon dioxide emission amount is not particularly limited.

[0041] Furthermore, depending on the delivery method, the transportation distance and fuel consumption may change depending on the season, day of the week, events, the number of delivery requests, weather, etc. The events may be real events or events on e-commerce sites, etc. Therefore, the acquisition unit 206 may acquire at least one of the delivery season, delivery day of the week, events, the number of delivery requests, and weather data on the delivery date. The emission amount calculation unit 201 may then calculate the carbon dioxide emission amount using data such as the season, day of the week, events, the number of delivery requests, and weather.

[0042] Take the ton-kilometer method, which multiplies the weight of a package by the distance it is transported. For example, it may be predetermined that if an event occurs and the delivery method is truck, the average transport distance will increase by 2 km (kilometers). The emission calculation unit 201 then calculates the carbon dioxide emissions using the ton-kilometer method, using the transport distance obtained by adding the expected increased transport distance to the transport distance acquired in truck delivery.

[0043] In addition, in the above example, an example was given in which the additional transport distance was determined depending on whether or not an event occurred, but the additional transport distance may also be defined depending on the type of event. For example, for each delivery method, the additional transport distance may be determined in advance by season, day of the week, number of delivery requests, weather, etc. Furthermore, the items defined may differ depending on the calculation method, without being limited to the additional transport distance. In this way, by calculating the carbon dioxide emissions using the delivery season, delivery day of the week, event, number of delivery requests, weather data, etc., it is possible to calculate the carbon dioxide emissions more accurately.

[0044] For example, the reduction amount calculation unit 202 calculates the amount of carbon dioxide reduction when switching from the current delivery method to another delivery method, based on the emissions calculated for the current delivery method and another delivery method.

[0045] Next, the output control unit 203 presents the calculated reduction amount. As described in the first embodiment, the method by which the output control unit 203 presents the reduction amount is not particularly limited. In the second embodiment, an example will be described in which the output control unit 203 displays the calculated reduction amount on the display device of the terminal device 21 of the shipper.

[0046] There may be multiple alternative delivery methods. For example, the current delivery method may be a diesel truck, and the alternative delivery methods may be electric trucks, ships, etc. The emission calculation unit 201 calculates the amount of carbon dioxide emissions for the current delivery method and each of the multiple alternative delivery methods. The reduction calculation unit 202 calculates the amount of carbon dioxide reduction that would occur if the current delivery method were switched to another delivery method, based on the calculated emission amount for each of the multiple alternative delivery methods. Then, the output control unit 203 presents the calculated reduction amount for each of the multiple alternative delivery methods.

[0047] Furthermore, for example, the output control unit 203 may present the reduction amount for each of a plurality of other delivery methods in descending order of the calculated reduction amount. Specifically, for example, the output control unit 203 may present the reduction amount for each of a plurality of other delivery methods in descending order of the calculated reduction amount. Note that the output control unit 203 may present the reduction amount together with the order.

[0048] Furthermore, for example, the output control unit 203 may present the reduction amount for an alternative delivery method selected from among a plurality of alternative delivery methods based on the calculated reduction amount. Specifically, for example, the output control unit 203 may present the reduction amount for an alternative delivery method from among the plurality of alternative delivery methods whose calculated reduction amount is equal to or greater than a predetermined value. Alternatively, for example, the output control unit 203 may present the reduction amount for a predetermined number of alternative delivery methods selected from among the plurality of alternative delivery methods based on the calculated reduction amount. The predetermined number is not particularly limited. More specifically, for example, the output control unit 203 may present the reduction amount for a predetermined number of alternative delivery methods selected from among the plurality of alternative delivery methods in descending order of the calculated reduction amount.

[0049] Furthermore, depending on the additional fee, the shipper may be able to select a more environmentally friendly delivery method. For example, if the additional fee is low, the shipper may select the more environmentally friendly delivery method. The delivery fee for the current delivery method and the delivery fee for the other delivery method may also be derived using existing technology. Therefore, each delivery fee may be stored in a database or the like in advance. The acquisition unit 206 then acquires the delivery fees for the current delivery method and the other delivery method from the database or the like. Then, for example, the identification unit 205 identifies the additional fee that would be incurred if the current delivery method were switched to the other delivery method. Specifically, for example, the identification unit 205 identifies the additional fee as the fee obtained by subtracting the delivery fee for the other delivery method from the delivery fee for the current delivery method.

[0050] Alternatively, the acquisition unit 206 acquires information related to the calculation of delivery fees from a database or the like. The determination unit 205 may calculate each delivery fee using existing technology and determine an additional fee based on the calculated delivery fees. In this way, the delivery support system 20 may have a function for calculating delivery fees.

[0051] The output control unit 203 then presents the calculated reduction amount and the additional fee. For example, the output control unit 203 causes the calculated reduction amount and the additional fee to be displayed on the display device of the terminal device 21. For example, the output control unit 203 may cause the display device of the terminal device 21 to display the calculated reduction amount and the additional fee for delivery methods whose additional fee is equal to or less than a predetermined amount. Alternatively, for example, the output control unit 203 may cause the display device of the terminal device 21 to display the calculated reduction amount and the additional fee for delivery methods selected in ascending order of additional fee.

[0052] Alternatively, for example, the output control unit 203 may display the calculated reduction amount and additional fee on the display device of the terminal device 21 for a predetermined number of delivery methods in order of decreasing additional fee, where the additional fee is less than a predetermined amount.

[0053] Furthermore, the reception unit 204 receives a request to switch to another delivery method after the reduction amount is presented. For example, the reception unit 204 may receive a request to switch to another delivery method through an operation by the shipper. More specifically, for example, the reception unit 204 may receive a request to switch to another delivery method through an operation by the shipper via the shipper's terminal device 21.

[0054] 6 is an explanatory diagram showing an example of presenting the calculated reduction amount and additional fee for each of a plurality of different alternative delivery methods. A screen including the CO2 reduction amount and additional fee for each delivery method is displayed on the shipper's terminal device 21.

[0055] The screen shows that the current delivery method is "diesel truck," the amount of cargo is "100 pallets," the destination is "xxx," and the transport distance is "100km." The screen also shows the CO2 reduction amount and additional fee for each of "electric truck" and "ship." 。

[0056] In Figure 6, for the delivery method "electric truck", the CO2 reduction amount is "x%" and the additional fee is "xxxx yen". For the delivery method "ship", the CO2 reduction amount is "y%" and the additional fee is "yyyy yen".

[0057] The screen may also be a screen that allows the current delivery method, "diesel truck," to be changed to either "electric truck" or "ship." In FIG. 6, the screen includes a button for selecting "electric truck" and a button for selecting "ship." In the example of FIG. 6, "electric truck" is selected.

[0058] The screen also includes a "Change" button. For example, when the "Change" button is pressed, the accepting unit 204 accepts a change of the delivery method from "Diesel Truck" to the selected "Electric Truck."

[0059] Furthermore, the output control unit 203 may present the delivery fee if the shipper delivers alone, rather than through joint delivery. For example, the output control unit 203 may present the delivery fee if the shipper delivers alone and the delivery fee for each delivery method. The delivery fee for delivery by the shipper alone may be acquired by the acquisition unit 206 or may be newly calculated. Alternatively, for example, the output control unit 203 may present the difference between the delivery fee if the shipper delivers alone and the delivery fee for each delivery method. However, if the delivery fee for each delivery method is lower than the delivery fee if the shipper delivers alone, the output control unit 203 may present the delivery fee if the shipper delivers alone.

[0060] Here, an example will be given in which the reduction amount is presented to a specific shipper. For example, when a delivery method is changed, the partner of a joint delivery for a specific shipper may change. The shipper may select a different delivery method depending on the partner of the joint delivery. For example, if the partner of the joint delivery is an environmentally conscious company, this will have the effect of encouraging the shipper to reduce carbon dioxide emissions. Therefore, for example, the acquisition unit 206 acquires information about the partner of the joint delivery. As described above, the information about the partner of the joint delivery includes at least one of the name of the shipper, the type of business of the shipper, the type of power generation by the shipper, and information about the environmental activities by the shipper. Specifically, for example, the acquisition unit 206 acquires, from the shipper DB 2002, information about the shipper associated with shipper identification information that identifies the partner of the joint delivery as information about the partner of the joint delivery.

[0061] The output control unit 203 presents the information about the other party of the joint delivery and the reduction amount to the shipper. For example, the output control unit 203 causes the information about the other party of the joint delivery and the reduction amount to be displayed on the terminal device 21 of the shipper.

[0062] Fig. 7 is an explanatory diagram showing an example of presenting the calculated reduction amount and additional fee for each of a plurality of different alternative delivery methods. The screen shown in Fig. 7 includes information about the other party of the joint delivery in addition to the screen shown in Fig. 6.

[0063] In FIG. 7, the shipper's terminal device 21 displays a screen including the name of the partner of the joint delivery, the amount of CO2 reduction, and an additional fee as information relating to the partner of the joint delivery for each delivery method.

[0064] In Figure 7, for the delivery method "electric truck," the joint delivery partners are "Company A, Company B, Company C," the CO2 reduction amount is "x%," and the additional fee is "xxxx yen." For the delivery method "ship," the joint delivery partners are "Company G, Company H, Company I," the CO2 reduction amount is "y%," and the additional fee is "yyyy yen."

[0065] Here, the screen shown in FIG. 7 is not particularly limited to the same functions as those of the screen shown in FIG.

[0066] For example, when the name of a partner in a joint delivery is selected, the output control unit 203 may output information about the partner in the joint delivery. In FIG. 7, for example, the names of "Company A, Company B, and Company C" may be selectable. For example, when a cursor or the like is placed over the name of each shipper, more detailed information about the partner in the joint delivery may be displayed.

[0067] In the example of Figure 7, the additional fee is presented as the same for the same delivery method, but even for the same delivery method, the delivery fee may differ depending on the joint delivery partner, so the additional fee may vary. Therefore, the identification unit 205 may identify the additional fee for each joint delivery partner. Then, the output control unit 203 may present the CO2 reduction amount and the additional fee for each joint delivery partner.

[0068] 8 is an explanatory diagram showing an example of presenting more detailed information about the other party of the joint delivery. The output control unit 203 displays information about the other party of the joint delivery superimposed on the screen shown in FIG.

[0069] The screen shown in Figure 8 displays information about the joint delivery partner, "Company A," including the industry, type of power generation, and environmental activities when the delivery method is "electric truck." For example, in Figure 8, the industry is "manufacturing," the type of power generation is "wind power generation," and the environmental activity is "use of renewable energy."

[0070] Returning to the explanation of Figure 5, there are cases where multiple combinations of joint deliveries are possible. In such cases, there may be multiple partners in the joint delivery. Therefore, the emission calculation unit 201 calculates the emission amount for each of the current delivery method and another delivery method for each shipper in the joint delivery. Here, for example, the shipper for which the emission amount is calculated may be each combination of shippers in the joint delivery. In an example where the emission amount is presented to a specific shipper, the emission calculation unit 201 calculates the emission amount for each of the current delivery method and another delivery method for each specific partner and each shipper in the joint delivery other than the specific partner.

[0071] Then, the reduction amount calculation unit 202 calculates the amount of carbon dioxide reduction for each joint delivery partner based on the calculated emissions when the current delivery method is switched to another delivery method.

[0072] The output control unit 203 presents the calculated reduction amount for each joint delivery partner.

[0073] The specifying unit 205 may also specify an additional fee for each joint delivery partner. Then, the output control unit 203 presents the calculated reduction amount and additional fee for each joint delivery partner.

[0074] 9 is an explanatory diagram showing an example of presenting the amount of reduction for each joint delivery partner. For example, the shipper's terminal device 21 displays a screen including the amount of CO2 reduction and additional fees for each joint delivery partner for each delivery method. Detailed explanations of the parts of the screen shown in FIG. 9 that are the same as those of the screen shown in FIG. 6 and the screen shown in FIG. 7 will be omitted.

[0075] The screen shown in FIG. 9 includes, in addition to the screen shown in FIG. 6, information about the joint delivery partner, the amount of carbon dioxide reduction, and an additional fee for each joint delivery partner.

[0076] In Figure 9, when the other delivery method is "electric truck," the joint delivery partners are either "Company A, Company B, Company C" or "Company D, Company E, Company F." In the case of "Company A, Company B, Company C," the amount of carbon dioxide reduction is "xx%" and the additional fee is "xxxx yen." In the case of "Company D, Company E, Company F," the amount of carbon dioxide reduction is "xy%" and the additional fee is "xxyy yen."

[0077] In Figure 9, when the other delivery method is "ship," the joint delivery partners are either "Company G, Company H, Company I" or "Company J, Company K." In the case of "Company G, Company H, Company I," the carbon dioxide reduction amount is "yy%" and the additional charge is "yyyy yen." In the case of "Company J, Company K," the carbon dioxide reduction amount is "yx%" and the additional charge is "yyxx yen."

[0078] For example, the delivery method and the partner for joint delivery may be selectable. In FIG. 9, the screen has buttons for selecting each partner for joint delivery. Therefore, when a button is selected, the partner for joint delivery can be selected. In FIG. 9, there are buttons for "Company A, Company B, Company C," "Company D, Company E, Company F," "Company G, Company H, Company I," and "Company J, Company K."

[0079] 9, the delivery method "electric truck" and the joint delivery partners "Company A, Company B, Company C" are selected. For example, when the "Change" button is pressed, the reception unit 204 receives a change from the current delivery method to the selected delivery method and joint delivery partners.

[0080] Also, although detailed explanation will be omitted, in Fig. 9, for example, it is possible to select the name of each shipper, such as "Company A" from among "Company A, Company B, Company C," "Company D, Company E, Company F," "Company G, Company H, Company I," and "Company J, Company K," as in Fig. 7. For example, when the cursor or the like is placed on the name of each shipper, more detailed information about the partner of the joint delivery may be displayed, as in Fig. 8.

[0081] In the above example, the emission amount calculation unit 201 calculates the amount of carbon dioxide emissions for each of the current delivery method and the other delivery methods based on a plurality of different calculation methods. As described above, the calculation method is not particularly limited, and any existing technology may be used, such as the ton-kilometer method that uses the multiplication of weight and transport distance, the fuel method that uses fuel consumption, or the fuel efficiency method that uses transport distance and fuel efficiency. The reduction amount calculation unit 202 may then calculate the amount of carbon dioxide reduction for each calculation method.

[0082] Then, the output control unit 203 presents the amount of carbon dioxide reduction for each calculation method.

[0083] Fig. 10 is an explanatory diagram showing an example of presenting the amount of carbon dioxide reduction for each calculation method. The screen shown in Fig. 10 further displays the amount of carbon dioxide reduction for each calculation method in addition to the screen shown in Fig. 9.

[0084] In the above description, the methods by which the output control unit 203 presents the reduction amounts may be combined. For example, the output control unit 203 may present the carbon dioxide reduction amount for each delivery method selected from multiple other delivery methods in descending order of reduction amount, with an additional fee equal to or less than a predetermined amount.

[0085] Furthermore, for example, the output control unit 203 may present a reduction amount selected from the reduction amounts calculated for each of a plurality of calculation methods for another delivery method. For example, the output control unit 203 may present the largest reduction amount from the reduction amounts calculated for each of a plurality of calculation methods for another delivery method.

[0086] In the above description, the acquiring unit 206 acquires various pieces of information from a database, but the present invention is not limited to this. For example, the acquiring unit 206 may acquire various pieces of information via the communication network NT, and the method by which the acquiring unit 206 acquires various pieces of information is not particularly limited.

[0087] (flowchart) 11 is a flowchart showing an example of an operation of the delivery support system 20 according to the second embodiment. Here, as an example, a case where there is one type of other delivery method will be described.

[0088] The acquisition unit 206 acquires information about the current delivery method, information about other delivery methods, and information about the other party in the joint delivery (step S201).

[0089] The emission amount calculation unit 201 calculates the amount of carbon dioxide emission for each of the current delivery method and the other delivery methods (step S202).

[0090] The reduction amount calculation unit 202 calculates the amount of carbon dioxide reduction when switching from the current delivery method to another delivery method, based on the amount of carbon dioxide emission for each of the current delivery method and the other delivery method (step S203).

[0091] The specifying unit 205 specifies the additional fee when switching from the current delivery method to another delivery method (step S204).

[0092] Next, the output control unit 203 presents the information regarding the reduction amount, the additional fee, and the partner of the joint delivery to the shipper (step S205). In step S205, the output control unit 203 may cause the information regarding the reduction amount, the additional fee, and the partner of the joint delivery to be displayed on the display device of the shipper's terminal device 21. Then, the delivery support system 20 ends the processing.

[0093] As described above, in the second embodiment, the delivery support system 20 calculates the amount of carbon dioxide reduction when switching from the current delivery method to another delivery method in joint delivery, and presents the calculated reduction amount. Therefore, it is possible to promote the use of environmentally friendly delivery methods.

[0094] In addition, there may be multiple possible combinations of joint deliveries. Therefore, the delivery support system 20 calculates the amount of carbon dioxide reduction that would occur if the current delivery method were switched to another delivery method for each joint delivery partner, and presents the amount of carbon dioxide reduction for each joint delivery partner. This allows the amount of carbon dioxide reduction that would occur if the current delivery method were switched to another delivery method to be confirmed for each joint delivery partner.

[0095] For example, if the joint delivery partner is an environmentally conscious company, it can be effective in appealing to the shipper to reduce carbon dioxide emissions. The delivery support system 20 presents information about the joint delivery partner along with the calculated reduction amount. The information about the joint delivery partner includes at least one of the following: the name of the joint delivery partner, the industry of the joint delivery partner, the type of power generation by the joint delivery partner, and information about the joint delivery partner's environmental activities. This can promote the use of delivery methods that reduce carbon dioxide emissions significantly.

[0096] For example, if the additional fee is small, the shipper may switch to a more environmentally friendly delivery method. Therefore, the delivery support system 20 identifies the additional fee that would be incurred if the current delivery method were switched to another delivery method, and presents the carbon dioxide reduction amount and the identified additional fee. This can promote the use of environmentally friendly delivery methods. Furthermore, the delivery support system 20 may present the carbon dioxide reduction amount and the identified additional fee if the additional fee is equal to or less than a predetermined amount. It is possible to narrow down the delivery methods to those with low additional fees in advance and present the carbon dioxide reduction amount.

[0097] The delivery support system 20 calculates the amount of carbon dioxide reduction that would occur if the current delivery method were switched to another delivery method for each of a number of different alternative delivery methods, and presents the reduction amounts for each of the multiple alternative delivery methods in descending order of the reduction amounts.

[0098] Furthermore, the delivery assistance system 20 presents the calculated reduction amount for another delivery method selected from a plurality of other delivery methods based on the reduction amount.

[0099] Furthermore, the delivery support system 20 calculates the amount of carbon dioxide emissions for each of the current delivery method and another delivery method based on each of a plurality of different calculation methods.

[0100] The delivery support system 20 calculates carbon dioxide emissions based on at least one of the following: delivery season, delivery day, event, number of delivery requests, and weather data. This allows for more accurate calculation of carbon dioxide emissions by using factors that affect the transportation distance, etc., in the calculation of carbon dioxide emissions.

[0101] Furthermore, the delivery support system 20 accepts a switch to another delivery method after the reduction amount has been presented. For example, the delivery support system 20 accepts a switch to another delivery method by an operation of the shipper via the shipper's terminal device 21 after the reduction amount has been presented. This allows the shipper to select an environmentally friendly delivery method.

[0102] The above is the explanation of each embodiment. Each embodiment may be modified and used.

[0103] <Variation 1> For example, in each embodiment, an example has been described in which the difference between the emissions is calculated as the reduction amount after the emissions are calculated, but the reduction amount may be calculated directly. In such a case, for example, the delivery support system 20 may be configured to include a reduction amount calculation unit 202 and an output control unit 203.

[0104] <Variation 2> In each embodiment, an example has been described in which the output control unit 203 presents the amount of carbon dioxide reduction to a shipper. For example, the output control unit 203 may present the amount to a logistics company. When presenting the amount to a logistics company, the output control unit 203 may display the amount of carbon dioxide reduction on a display device of a terminal device 21 of the logistics company. Furthermore, the delivery support system 20 may be equipped with an output device, and the output control unit 203 may present the amount of carbon dioxide reduction on the output device of the delivery support system 20. In this way, the recipient of the presentation is not limited to a shipper or a logistics company, and may be determined as appropriate.

[0105] <Variation 3> For example, the output control unit 203 may present information about general delivery methods together with each delivery method. For example, some delivery methods may result in lower taxes. In such cases, the output control unit 203 may present the fact that the tax will be lower for the delivery method along with the amount of tax reduction.

[0106] <Variation 4> In addition, an incentive may be provided depending on the delivery method recommended by the logistics company. The incentive may be points, discounts, or the like, and is not particularly limited. For this reason, the output control unit 203 may present the incentive to be provided for other delivery methods along with the reduction amount. This makes it possible to more effectively recommend delivery methods that are effective in reducing carbon dioxide emissions.

[0107] This concludes the description of each modified example. Note that each embodiment and each modified example may be used in combination. Also, for example, in each embodiment, the delivery support system may be configured to include each functional unit and part of the information.

[0108] Furthermore, each embodiment and each modified example is not limited to the examples described above, and various modifications are possible. Furthermore, the configuration of the delivery support system in each embodiment is not particularly limited. For example, the delivery support system may be realized by a single device (e.g., a delivery support device) such as a single terminal device or a single server. Alternatively, the delivery support system may be realized by different devices for different functions or data. For example, the delivery support system may be configured by multiple servers.

[0109] In each embodiment, each piece of information may include part of the information described above. Also, each piece of information may include information other than the information described above. Each piece of information may be divided into more detailed tables or pieces of information. In this way, the method for realizing each piece of information is not particularly limited.

[0110] Furthermore, each screen is merely an example and is not particularly limited. Buttons, lists, check boxes, information display fields, input fields, etc. (not shown) may be added to each screen. Furthermore, the background color of the screen may be changed.

[0111] In addition, for example, in each embodiment, the process of generating information on a screen to be displayed on a terminal device may be performed by an output control unit of the delivery support system. Also, this process may be performed by the terminal device.

[0112] (Example of computer hardware configuration) Next, an example of a hardware configuration in which each device, such as the delivery support system and terminal device described in each embodiment, is implemented by a computer will be described. Fig. 12 is an explanatory diagram showing an example of a hardware configuration of a computer. For example, some or all of each device can be implemented using any combination of a computer 80 and a program as shown in Fig. 12.

[0113] The computer 80 includes, for example, a processor 801, a read-only memory (ROM) 802, a random access memory (RAM) 803, and a storage device 804. The computer 80 also includes a communication interface 805 and an input / output interface 806. The components are connected to each other, for example, via a bus 807. The number of each component is not particularly limited, and there may be one or more of each component.

[0114] The processor 801 controls the entire computer 80. Examples of the processor 801 include a CPU (Central Processing Unit), a DSP (Digital Signal Processor), and a GPU (Graphics Processing Unit). The computer 80 has a storage unit including a ROM 802, a RAM 803, and a storage device 804. Examples of the storage device 804 include a semiconductor memory such as a flash memory, a hard disk drive (HDD), and a solid state drive (SSD). For example, the storage device 804 stores an operating system (OS) program, application programs, and programs according to the embodiments. Alternatively, the ROM 802 stores application programs and programs according to the embodiments. The RAM 803 is used as a work area for the processor 801.

[0115] The processor 801 also loads programs stored in the storage device 804, ROM 802, etc. The processor 801 then executes each process coded in the program. The processor 801 may also download various programs via the communication network NT. The processor 801 also functions as a part or all of the computer 80. The processor 801 may then execute the processes or instructions in the illustrated flowchart based on the program.

[0116] The communication interface 805 is connected to a communication network NT such as a LAN (Local Area Network) or WAN (Wide Area Network) via a wireless or wired communication line. The communication network NT may be composed of multiple communication networks NT. As a result, the computer 80 is connected to external devices and external computers 80 via the communication networks NT. The communication interface 805 serves as an interface between the communication network NT and the inside of the computer 80. The communication interface 805 also controls the input and output of data from external devices and external computers 80.

[0117] Furthermore, the input / output interface 806 is connected to at least one of an input device, an output device, and an input / output device. The connection method may be wireless or wired. Examples of input devices include a keyboard, a mouse, and a microphone. Examples of output devices include a display device, a lighting device, and a speaker that outputs audio. Examples of input / output devices include a touch panel display. Note that the input device, output device, and input / output device may be built into the computer 80 or may be external.

[0118] The hardware configuration of the computer 80 is an example. The computer 80 may have some of the components shown in FIG. 12. The computer 80 may have components other than those shown in FIG. 12. For example, the computer 80 may have a drive device or the like. The processor 801 may then read programs and data stored in a recording medium attached to the drive device or the like into the RAM 803. Examples of non-transitory tangible recording media include optical disks, flexible disks, magneto-optical disks, and USB (Universal Serial Bus) memories. As described above, the computer 80 may have input devices such as a keyboard and a mouse. The computer 80 may have an output device such as a display. The computer 80 may also have an input device, an output device, and an input / output device.

[0119] The computer 80 may also have various sensors (not shown). The types of sensors are not particularly limited.

[0120] This concludes the description of the hardware configuration of each device. There are various variations in the method of realizing each device. For example, each device may be realized by any combination of a different computer and program for each component. Furthermore, multiple components of each device may be realized by any combination of a single computer and program.

[0121] Furthermore, some or all of the components of each device may be realized by circuits for specific applications. Furthermore, some or all of the components of each device may be realized by general-purpose circuits including a processor such as an FPGA (Field Programmable Gate Array). Furthermore, some or all of the components of each device may be realized by a combination of circuits for specific applications and general-purpose circuits. Furthermore, these circuits may be a single integrated circuit. Alternatively, these circuits may be divided into multiple integrated circuits. Furthermore, the multiple integrated circuits may be configured by being connected via a bus or the like.

[0122] Furthermore, when some or all of the components of each device are realized by a plurality of computers, circuits, etc., the plurality of computers, circuits, etc. may be centrally located or distributed.

[0123] The delivery support method described in each embodiment is realized by execution by a delivery support system. Furthermore, for example, the delivery support method is realized by execution of a prepared program by a computer such as a server or a terminal device. The program described in each embodiment is recorded on a computer-readable recording medium such as an HDD, SSD, flexible disk, optical disk, flexible disk, magneto-optical disk, or USB memory. The program is then executed by being read from the recording medium by the computer. Furthermore, the program may be distributed via a communication network NT.

[0124] The functions of each component of the delivery support system in each embodiment described above may be realized by hardware, such as a computer, or may be realized by a computer or firmware under program control.
