[0009] DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A carbon dioxide emission management system according to an embodiment of the present invention will now be described with reference to the drawings. In this embodiment, carbon dioxide may be written as CO2.

[0010] As efforts to reduce CO2 emissions are being called for in various industries, the logistics industry also faces an urgent need to reduce CO2 emissions from transportation methods used when transporting transportation means, motor vehicles, fuel, etc. However, even if shippers want to use other transportation means to reduce CO2 emissions, they need a huge amount of data on other transportation means and CO2 emissions, making it practically difficult to quantitatively consider and select other transportation means.

[0011] In addition, shippers who commission transport services from transport companies are required to submit regular reports on CO2 emissions to the government. Shippers receive information on CO2 emissions from transport companies and submit regular reports. Even if a system for submitting regular reports and related systems are established, basic information such as the departure and arrival points for the transport route is entered manually, and input errors often occur, which can prevent smooth processing.

[0012] The CO2 emission management system of this embodiment is a system for solving such problems, and is a system that can suggest other means of transportation to reduce CO2 emissions and convert inaccurate input into correct notation.

[0013] Fig. 1 is a diagram showing an example of the configuration of a CO2 emission management system 100. As shown in Fig. 1, the CO2 emission management system 100 is composed of a CO2 emission management device 10, a plurality of shipper terminals 15, and a plurality of transport company terminals 20. The CO2 emission management device 10, the shipper terminals 15, and the transport company terminals 20 are connected via a network 30.

[0014] The CO2 emission management device 10 receives information on the transportation route and transportation performance of the transportation company from the transportation company terminal 20, and calculates the CO2 emission amount by the specified CO2 emission calculation method. The CO2 emission management device 10 transmits the calculated data on the CO2 emission amount to the transportation company terminal 20 or the shipper terminal 15 upon request. The CO2 emission management device 10 also has a function of creating a regular report on the CO2 emission amount and transmitting it to the shipper terminal 15. Furthermore, the CO2 emission management device 10 accepts a request from the shipper terminal 15 for a proposal of an alternative means for reducing the CO2 emission amount on a specific transportation route, calculates the alternative means, and responds with the calculation result to the shipper terminal 20. If there is an error in the information on the departure point, arrival point, etc. related to the transportation route, the CO2 emission management device 10 converts the information into a notation that corrects the error, and executes the calculation of the CO2 emission amount, etc.

[0015] The shipper terminal 15 is an information processing device managed by a shipper business operator who has introduced and is using the CO2 emission management system 100. The shipper terminal 15 has a function of receiving data related to CO2 emissions from the CO2 emission management device 10 and displaying information corresponding to the received data. The shipper terminal 15 also receives periodic reports related to CO2 emissions from the CO2 emission management device 10. Furthermore, the shipper terminal 15 transmits a request to the CO2 emission management device 100 for a proposal of alternative means for reducing CO2 emissions on a specific transportation route, and receives a response specifying the proposal, which is the result of the calculation.

[0016] The transport company terminal 20 is an information processing device managed by a transport company (logistics company) that introduces and uses the CO2 emission management system 100. The transport company terminal 20 transmits data on transport routes and transport performance input by users such as staff of the transport company to the CO2 emission management device 10. The transport company terminal 20 also has a function of receiving data on CO2 emissions from the CO2 emission management device 10 and displaying information corresponding to the received data. Furthermore, the transport company terminal 20 receives information related to alternative means for reducing CO2 emissions from the CO2 emission management device 10, displays information corresponding to the received data, and accepts instructions from the user.

[0017] The network 30 is a communication network capable of transmitting various types of information, such as the Internet, a mobile communication network, a VPN (Virtual Private Network), or a dedicated line.

[0018] In this way, the CO2 emission management system 100 calculates and aggregates the CO2 emissions of transport businesses, and the data related to the calculated CO2 emissions can be referenced by the shipper terminal 15 and the transport business terminal 20. Furthermore, the CO2 emission management system 100 has a function of creating a regular report on CO2 emissions and sending it to the shipper terminal 15. In addition, when a request is made from the shipper terminal 15 for a proposal for a means of transport to reduce CO2 emissions, the CO2 emission management system 100 has a function of calculating an alternative means of transport and sending a response proposing the calculated means of transport to the shipper terminal 15. This will be described in more detail later.

[0019] As shown in Fig. 1, this embodiment assumes that a CO2 emission management system 100 is used between multiple shippers and multiple transport companies. Therefore, in the CO2 emission management system 100 shown in Fig. 1, multiple shipper terminals 15 and multiple transport company terminals 20 are connected to the CO2 emission management device 10 via a network 30. Note that, although two shipper terminals 15 and three transport company terminals 20 are shown in Fig. 1, this is just an example, and the numbers can be arbitrary depending on the number of shippers and transport companies.

[0020] The CO2 emission management device 10, the shipper terminal 15, and the transport company terminal 20 are configured with information processing devices such as personal computers, smartphones, tablet terminals, etc. Fig. 2 is a block diagram showing an example of the hardware configuration of the information processing device. As shown in Fig. 2, the information processing device includes, for example, a display 40, an input device 41, a communication interface 42, a CPU (Central Processing Unit) 43, a ROM (Read Only Memory) 44, a RAM (Random Access Memory) 45, and an auxiliary storage device 46.

[0021] The display 40 includes a display device such as a liquid crystal display, an organic EL (Electro Luminescence) display, etc. Under the control of the CPU 43, the display 40 displays various screens and the like in response to user operations.

[0022] The input device 41 is configured with a keyboard, a touch panel, a mouse, etc., and receives operation input from a user and sends a signal related to the received operation to the CPU 43.

[0023] The communication interface 42 is hardware for communicating via the above-mentioned network 30, and is, for example, a wired or wireless LAN (Local Area Network) module.

[0024] The CPU 43 performs overall control of the information processing device. The ROM 44 stores various data and operation programs executed by the CPU 43. The RAM 45 is used as a working area for the CPU 43.

[0025] The auxiliary storage device 46 is composed of a readable / writable nonvolatile semiconductor memory. The readable / writable nonvolatile semiconductor memory is, for example, an EEPROM (Electrically Erasable Programmable Read-Only Memory), a flash memory, etc. The auxiliary storage device 46 stores various data and application programs (particularly data and application programs related to the CO2 emission management system 100).

[0026] The configuration of the information processing device shown in FIG. 2 is just an example, and is not limited to that shown in FIG. 2 as long as it can function as the CO2 emission management device 10, the shipper terminal 15, and the transport company terminal 20 of this embodiment.

[0027] 3 is a functional block diagram showing an example of the functional configuration of the CO2 emission management device 10. The CO2 emission management device 10 includes, as its functional configuration, a transportation route registration unit 101, a calculation method designation unit 102, a transportation record registration unit 103, an addition unit 104, a request reception unit 105, a search unit 106, a proposal unit 107, a database (DB) 108, a conversion unit 109, a calculation unit 110, and an output unit 111. The CPU 43 of the information processing device reads a program stored in the ROM 44 or the auxiliary storage device 46, thereby functioning as the CO2 emission management device 10 and realizing the functions of these functional units.

[0028] The transportation route registration unit 101 receives information about the transportation route from the transportation company terminal 20, and registers it in the DB 108. This information about the transportation route includes information about the departure point and the arrival point.

[0029] The calculation method designation unit 102 accepts designation of a CO2 emission calculation method for a transportation route from the transportation company terminal 20, and registers it in the DB 108 in association with the transportation route.

[0030] The transportation record registration unit 103 receives a transportation record registration request for registering the transportation record from the transport business terminal 20, and registers the transportation record including the transportation means in a predetermined transportation route and the CO2 emission amount based on the transportation means in the DB 108. The transportation means includes, for example, a transportation means, a vehicle type based on a prime mover, and a type of fuel. The transportation means is a transportation means for transportation including a truck, a train, a ship, and an airplane. The vehicle type based on a prime mover is a type of automobile based on a prime mover when the transportation means is a truck, and includes, for example, a diesel vehicle, a gasoline vehicle, a HV (Hybrid Vehicle) vehicle, an EV (Electric Vehicle) vehicle, and a fuel cell vehicle, which are prime movers of an engine. The type of fuel is a type of fuel used in an engine-equipped vehicle, and includes, for example, diesel, gasoline, LP gas, natural gas, synthetic fuel, and biofuel.

[0031] The adding unit 104 adds additional information (tag) designated when the transportation record is registered to the transportation record.

[0032] The request receiving unit 105 receives a proposal request from the shipper terminal 15, which requests a proposal for a transportation means for reducing CO2 emissions along a transportation route by specifying the transportation route.

[0033] The search unit 106 searches for other transportation means on the transportation route specified in the proposal request.

[0034] The proposal unit 107 first estimates the amount of CO2 emissions related to the other transportation means searched for by the search unit 106. Then, when the estimated CO2 emissions are smaller than the amount of CO2 emissions on the transportation route specified in the proposal request accepted by the request acceptance unit 105, the proposal unit 107 proposes the other transportation means found as a transportation means for reducing CO2 emissions on the specified transportation route.

[0035] DB108 is composed of the auxiliary storage device 46, and stores information on transportation routes, CO2 emission calculation methods, transportation records, calculated CO2 emission amounts, additional information, map information, information on transportation networks such as roads, railways, and ship routes, a conversion table that links and registers partially missing address notations with valid address notations, and an available table that links and registers transportation routes with transportation means that can be used on the transportation routes. DB108 may be composed of an external storage device connected to the CO2 emission management device 10. Note that the valid address here refers to a valid address notation in the system, and refers to the correct notation when registering a transportation route (starting point, arrival point) in the CO2 emission management device 10.

[0036] The conversion unit 109 determines whether or not at least one of the departure point and the arrival point included in the transportation route includes an error, and if an error is included, converts the error into a corrected notation. In addition, the conversion unit 109 refers to the available transportation table, and if the transportation means included in the transportation record is not an available transportation means, converts it into an available transportation means.

[0037] The calculation unit 110 calculates the amount of CO2 emissions along the transportation route based on the transportation means along the transportation route. The calculation unit 110 calculates the amount of CO2 emissions along the transportation route based on the CO2 emission calculation method designated by the calculation method designation unit 102 and the transportation record registered by the transportation record registration unit 103. The calculation unit 110 also calculates the amount of CO2 emissions along the transportation route based on the notation converted by the conversion unit 109.

[0038] The output unit 111 outputs the CO2 emission amount related to the transportation record registered in the DB 108. The output unit 111 outputs information related to the CO2 emission amount of the transportation record extracted by the DB 108 based on the additional information to the shipper terminal 15 or the transport company terminal 20. The output unit 111 can also create and output a regular report on the CO2 emission amount.

[0039] In addition, the program that causes the information processing device to function as the CO2 emission management device 10 can also be stored and distributed on a computer-readable recording medium such as a CD (Compact Disc)-ROM, a DVD (Digital Versatile Disc), an optical magnetic disk, a USB (Universal Serial Bus) memory, a memory card, an HDD (Hard Disk Drive), or an SSD (Solid State Drive).

[0040] Next, the operation of the CO2 emission management system 100 will be described. First, the process flow from registering a transportation route to registering a transportation record will be described. FIG. 4 is a sequence diagram showing the process flow from registering a transportation route to registering a transportation record in the CO2 emission management system 100. When a user on the transportation company side, such as a staff member of the transportation company, operates the transportation company terminal 20 to register a transportation route, a transportation route registration request (project registration request) is transmitted to the CO2 emission management device 10 (step S11). In this embodiment, one transportation route is called a project.

[0041] FIG. 5 is a diagram showing an example of a project (transportation route) registration screen displayed on the display screen (display 40) of the transport company terminal 20. In the project registration screen, the "project name", "shipper name", "transport company name", "start point", and "arrival point" can be input, and here, "project A", "shipper A", "transport company M", "AAA", and "BBB" are input, respectively. In the "start point" and "arrival point", the address is input. In addition, the CO2 emission calculation formula can be selected from "fuel method", "fuel efficiency method", "improved ton-kilometer method", and "conventional ton-kilometer method" in a so-called pull-down method, and here, "fuel method" is selected. After the user inputs the required items, by operating the registration button, a project registration request including the input information is transmitted to the CO2 emission management device 10. Note that input items other than the items shown in FIG. 5 may be provided. For example, the shipper name may be input by the sender name and the receiver name, and the distance of the transport route may be input. The project registration screen may be displayed on a web browser or by a dedicated application. The same applies to other screens.

[0042] Here, the fuel method is a calculation method that calculates CO2 emissions using the formula "CO2 emissions = fuel consumption x coefficient." The fuel consumption method is a calculation method that calculates CO2 emissions using the formula "CO2 emissions = transport distance / fuel consumption x coefficient." The improved ton-kilometer method is a calculation method that calculates CO2 emissions using the formula "CO2 emissions = transport volume (ton-kilometers) x improved ton-kilometer method CO2 emissions intensity x coefficient." The conventional ton-kilometer method is a calculation method that calculates CO2 emissions using the formula "CO2 emissions = transport volume (ton-kilometers) x conventional ton-kilometer method CO2 emissions intensity." Each coefficient can be a well-known coefficient determined by fuel type (for example, see the Joint Guidelines on CO2 Emissions Calculation Methods in the Logistics Field, Ver. 3.1 and 3.2).

[0043] Returning to FIG. 4, when the CO2 emission management device 10 receives a project registration request, it judges whether there is an error in the items included in the received project registration request. Specifically, in this embodiment, it judges whether there is an error in at least one of the departure point and the arrival point specified in the project registration request. Then, if there is an error, the conversion unit 109 of the CO2 emission management device 10 converts it to a notation that corrects the error (step S12). Note that, although errors in the departure point and the arrival point among the items included in the project registration request are corrected, errors in other items may also be corrected. For example, if a typographical error or redundant characters are included in the name of the shipper or the name of the transport company, the typographical error may be corrected or the redundant characters may be deleted. At this time, the correct shipper name and the transport company name may be judged based on the already registered project data, etc., by referring to DB 108.

[0044] At this time, the conversion unit 109 of the CO2 emission management device 10 refers to the map information stored in the DB 108 and judges whether or not at least one of the departure point and the arrival point is incomplete. This map information includes the addresses of all houses, facilities, etc., and the CO2 emission management device 10 judges whether or not there is an incompleteness by comparing the addresses of the departure point and the arrival point specified in the project registration request with the addresses included in the map information. Then, when the CO2 emission management device 10 judges that, for example, part of the address of the departure point or the arrival point (for example, the prefecture name, the city, ward, town, or village name) is missing, it refers to the conversion table T1 stored in the DB 108 and converts the incompleteness. The conversion table T1 is generated based on data related to past input errors, for example, and, as shown in the example of FIG. 6, a representation in which an address is missing is linked to a representation of a valid address. The valid representations of the representations in which a part of the address is missing, "Izumizaki 1, Naha City" and "Shin-Ogawa-cho 3-3, Shinjuku Ward", are "Izumizaki 1, Naha City, Okinawa Prefecture" and "Shin-Ogawa-cho 3-3, Shinjuku Ward, Tokyo", respectively. In this example, the address defect is that the prefecture name is missing, but it may be other defects such as missing city / town / village names. For example, the conversion table T1 may store addresses before and after the merger of municipalities, typographical errors such as incorrect kanji characters and correct spellings, and facility names and addresses in association with each other. In addition, if an address with a defect is not registered in the conversion table T1, a part of an address similar to the address with the defect or a valid spelling may be searched, and if a part of an address similar to the address with the defect or a valid spelling is found, the address with the defect may be converted to a valid spelling corresponding to the part of the address searched, or to the searched valid spelling. Then, the address with the defect may be newly registered in the conversion table T1 in association with the valid spelling converted this time. In this way, the data of the conversion table T1 can be automatically accumulated, and the accuracy of the conversion can be improved.

[0045] Also, for example, when the CO2 emission management device 10 determines that at least one of the addresses of the departure point and the arrival point specified in the project registration request contains a redundant portion, it deletes the redundant portion. For example, when the CO2 emission management device 10 determines that "qwr" is a redundant portion for the address "3-3qwr, Shin-Ogawa-cho, Shinjuku-ku, Tokyo (qwr is, for example, a building name or room number)" by comparing it with an address included in the map information, it deletes the redundant portion "qwr". Also, the CO2 emission management device 10 may delete the portion after the street address, for example.

[0046] Returning to FIG. 4, the CO2 emission management device 10 converts the start point and the arrival point specified in the project registration request into a representation in which the deficiencies are corrected, and registers the project data in the DB 108 (step S13). The project data corresponds to the information included in the project registration request after the conversion unit 109 converts the deficiencies into a representation in which the deficiencies are corrected, and is composed of "project name (route name)", "shipper name", "transportation company name", "CO2 emission calculation formula", "start point", "arrival point", "distance", and the like, as shown in FIG. 7(A). Note that the project data may contain other information. The "distance" may be automatically calculated based on the "start point", "arrival point" and map information, or the distance inputted in the transport company terminal 20 may be used. Note that if the "distance" inputted in the transport company terminal 20 is included, the value is given priority, and if it is not included, the "distance" is calculated from the "start point", "arrival point" and map information. In this case, the route is determined from the "start point", "arrival point" and map information, and the distance is calculated. The route determination may be changed depending on the delivery type (one-way, round (route delivery), round trip xn). In the case of route delivery, the distance changes depending on the delivery order. The delivery type may be specified when registering a transportation route in the transportation company terminal 20.

[0047] Also, for example, when the same address is specified for the "start point" and the "arrival point", the CO2 emission management device 10 may determine that the delivery is a route delivery and convert the "distance" to 30 km across the board. Also, when either the "start point" or the "arrival point" is missing, the CO2 emission management device 10 may determine that the delivery is a route delivery and convert the "distance" to 30 km across the board. By doing this, even if the route cannot be determined from the "start point" and the "arrival point" and the "distance" cannot be specified, it is assumed that the delivery is a route delivery and a hypothetical "distance" can be registered. This makes it possible to prevent an error from occurring when the "distance" is unknown and the CO2 emission calculation cannot be performed. The distance of 30 km may be different depending on the transportation means and the load. For example, the larger the load, the longer the distance may be set, or the distance may be changed depending on the size of the area to which the route delivery is performed, such as setting it so that remote islands < urban areas < regional cities < Hokkaido. This distance may be determined by a statistical judgment or an AI judgment. The route determination method shown here is just an example, and the determination may be made based on project data items (e.g., the name of the transport company, etc.) If there are no errors in the items included in the project registration request, the process of step S12 may be omitted, and in step S13, the project data according to the project registration request transmitted from the transport company terminal 20 may be registered.

[0048] Returning to FIG. 4, when a user on the transport company side performs an operation to register a transport record using the transport company terminal 20, a transport record registration request is transmitted to the CO2 emission management device 10 (step S21).

[0049] FIG. 8 is a diagram showing an example of a transportation record registration screen displayed on the display screen of the transportation business operator terminal 20. The transportation record registration screen is a screen for selecting a project and registering the transportation record for the transportation route of the project. The transportation record registration screen allows input of "transportation start date", "transportation end date", "transportation means", "values ​​required for CO2 emission calculation", and "tag name". In "transportation means", "truck", "railroad", "ship", and "airplane" can be selected in a pull-down manner in "transportation means". When "truck" is selected in "transportation means", "motor vehicle type" can be selected. In "motor vehicle type", "diesel vehicle", "gasoline vehicle", "HV vehicle", "EV vehicle", and "fuel cell vehicle" can be selected in a pull-down manner. When "diesel vehicle", "gasoline vehicle", or "HV vehicle" is selected in "motor vehicle type", "fuel type" can be selected. In "fuel type", "diesel oil", "gasoline", "LP gas", "natural gas", "synthetic fuel", and "biofuel" can be selected in a pull-down manner. Here, "Truck," "Diesel vehicle," and "Light oil" are selected for "Means of transportation," "Type of motor vehicle," and "Type of fuel," respectively.

[0050] In addition, in "Values ​​required for calculating CO2 emissions," "fuel consumption" can be input. This is because the formula for calculating CO2 emissions for project A is the fuel method, but the input items differ depending on the formula for calculating CO2 emissions selected on the project registration screen shown in Figure 5. If the formula for calculating CO2 emissions selected on the project registration screen is the "fuel method," the items required for calculation are "fuel consumption" and "fuel type," and since there is an item for "fuel type" in "transportation method," the input item is "fuel consumption." If the formula for calculating CO2 emissions selected on the project registration screen is the "fuel fuel consumption method," the items required for calculation are "weight," "vehicle fuel consumption," and "fuel type," and since there is an item for "fuel type" in "transportation method," the input items are "weight" and "vehicle fuel consumption." If the formula for calculating CO2 emissions selected on the project registration screen is the "improved ton-kilometer method," the items required for calculation are "weight," "maximum load capacity," "loading rate," and "fuel type," and since there is an item for "fuel type" in "transportation method," the input items are "weight," "maximum load capacity," and "loading rate." Furthermore, if the CO2 emission calculation formula selected on the project registration screen is the "conventional ton-kilometer method," the item required for the calculation is "weight," so the input item will be "weight." This allows the item corresponding to the selected CO2 emission calculation formula to be registered as the transportation record, allowing for optimal calculation of CO2 emissions.

[0051] In addition, in this embodiment, the user can add tags as additional information to the transportation record. The tag is a "tag name" which is any character information, and any number of tags can be added. Examples of tags include the shipper name, the product name, the product number, and the transportation route name. In this example, "shipper A" is input. Since such additional information can be added to the transportation record, the transportation record can be identified by the additional information and can be searched and extracted. Furthermore, since any tag can be set, it is possible to search and extract the transportation record as needed. After the user inputs the required items, a transportation record registration request including the input information is transmitted to the CO2 emission management device 10 by operating the registration button. Note that the transportation record registration screen may have input items other than the items shown in FIG. 8.

[0052] Returning to FIG. 4, when the CO2 emission management device 10 receives a transportation record registration request, it judges whether or not there is a defect in the items included in the received transportation record registration request. Specifically, in this embodiment, the conversion unit 109 of the CO2 emission management device 10 refers to the available table T2 stored in the DB 108, and if the transportation means included in the transportation record specified in the transportation record registration request is not an available transportation means, it converts it to an available transportation means (step S22). Note that in step S22, the CO2 emission management device 10 may judge whether or not there is a defect such as a missing weight, maximum loading capacity, loading rate, vehicle fuel efficiency, and fuel type required for CO2 emission calculation, and if there is a defect, convert it according to a predetermined standard. For example, it may refer to the DB 108 and adopt the average value of the items including the defect. Also, for example, a deemed table in which a provisional value is defined for each category such as transportation means or motor vehicle type may be prepared in the DB 108, and the provisional value defined in the deemed table may be adopted.

[0053] FIG. 9 is a diagram showing an example of the available table T2. In the available table T2, all patterns of transportation routes and available transportation means are linked and stored. For example, the transportation routes "Kisarazu City, Chiba Prefecture⇔Okushiri Town, Hokkaido" and "Miyakojima City, Okinawa Prefecture⇔Chiyoda Ward, Tokyo" require a sea route, so "ship" is linked as the "available transportation means". In addition, for example, the transportation route "Kisarazu City, Chiba Prefecture⇔Nasushiobara City, Tochigi Prefecture" is linked as the "available transportation means". For example, when the transportation route included in the transportation record specified in the transportation record registration request is "Kisarazu City, Chiba Prefecture⇔Okushiri Town, Hokkaido" and the transportation means "truck" is specified as the "transportation means", the conversion unit 109 refers to the available table T2 and converts it to "ship". In addition to the transportation means, the "available transportation means" in the available table T2 may also include the contents of the automobile type by the prime mover and the type of fuel efficiency.

[0054] Also, a remote island table for registering addresses of remote islands may be prepared in DB 108, and the transportation means may be converted to an appropriate one. For example, in this case, CO2 emission management device 10 refers to the remote island table, and converts the transportation means to "ship" when it determines that one of the addresses of the departure point and the arrival point included in the transportation route is the address of a remote island (step S22).

[0055] When the conversion unit 109 of the CO2 emission management device 10 converts the transportation means included in the transportation record specified in the transportation record registration request into an available transportation means as necessary, the calculation unit 110 calculates the CO2 emission amount based on the converted transportation means or the transportation means specified in the transportation record registration request (step S23). Also, for example, when the remote island table is referenced in step S22 and it is determined that one of the addresses of the departure point and the arrival point included in the transportation route is the address of a remote island, and the transportation means is converted to "ship", the carbon dioxide emission amount when the straight line distance connecting the departure point and the arrival point is navigated by "ship" is calculated. By calculating the carbon dioxide emission amount based on the straight line distance connecting the departure point and the arrival point, it is possible to calculate a provisional value while reducing the load on the CPU and making the processing simple. Note that when the transportation means is converted to "ship", if it is determined that the transportation route includes a part of a land route, the transportation means may be set to "ship" and "truck", and the CO2 emission amounts of the "ship" and "truck" may be added to calculate the CO2 emission amount of the transportation route.

[0056] Then, the CO2 emission management device 10 registers the transportation performance data in the DB 108 (step S24). The transportation performance data corresponds to the information included in the project registration request and the CO2 emission amount calculated in step S23, and is composed of "project name", "transportation start date", "transportation end date", "transportation means", "fuel usage", "CO2 emission amount", "weight, maximum load capacity, loading rate, vehicle fuel efficiency, fuel type", "tag name", etc., as shown in Fig. 7(B). Note that the transportation performance data may also include other information.

[0057] Next, the flow of processing from referring to the transportation record to outputting the CO2 emission data and outputting the regular report will be described. FIG. 10 is a sequence diagram showing the flow of processing from referring to the transportation record to outputting the CO2 emission data and outputting the regular report in the CO2 emission management system 100. When a user on the transportation company side, such as a staff member of the transportation company, performs an operation to refer to the transportation record using the transportation company terminal 20, a transportation record reference request is sent to the CO2 emission management device 10 (step S31). In this embodiment, the transportation record (CO2 emission amount) can be referenced by specifying a project and / or tag and a period. The transportation record reference request includes "project name and / or tag" and "period (start date and time, end date and time)" as shown in FIG. 7(C). It is also possible to refer to the transportation record without specifying a period (or by specifying the entire period).

[0058] Returning to FIG. 10, when the CO2 emission management device 10 receives the transportation performance reference request, it extracts from DB108 the data included in the "period" from the transportation performance data corresponding to the "project name and / or tag" included in the transportation performance reference request (step S32), and transmits it to the transportation company terminal 20 (step S33).

[0059] When a user on the transport company side performs an output operation of CO2 emission data related to one or more transport records using the transport company terminal 20, a CO2 emission output request is sent to the CO2 emission management device 10 (step S34). When the CO2 emission management device 10 receives the CO2 emission output request, it transmits the CO2 emission data of the corresponding transport record to the transport company terminal 20 in a specified graph or CSV (Comma-Separated Values) format. When the CO2 emission management device 10 receives the CO2 emission output request, it generates a graph or CSV data related to the CO2 emission of the transport record according to the CO2 emission output request and transmits it to the transport company terminal 20. The CO2 emission output request may include a specified period.

[0060] Furthermore, when a user on the transport company side performs an output operation of a periodic report related to one or more transport records using the transport company terminal 20, a CO2 emission periodic report output request is sent to the CO2 emission management device 10 (step S41). In the CO2 emission periodic report output request, the shipper to which the periodic report is to be sent can be specified. When the CO2 emission management device 10 receives the CO2 emission periodic report output request, it creates a periodic report in a format for submission to the government regarding the CO2 emission data of the corresponding transport records (step S42).

[0061] Then, the CO2 emission management device 10 transmits the created regular report to the transport business operator terminal 20 and the shipper terminal 15 of the designated shipper (step S43). The regular report transmitted to the transport business operator terminal 20 and the shipper terminal 15 can be output by printing or the like by the user and submitted to the government. This allows the shipper to obtain the regular report without performing any special processing. The regular report may be transmitted only to the shipper terminal 15, or may be transmitted to the transport business operator terminal 20 and then transmitted from the transport business operator terminal 20 or the CO2 emission management device 10 to the shipper terminal 15 after a confirmation process has been performed. Also, the transportation performance to be the subject of the regular report, the transmission destination of the regular report, and the transmission timing may be set in advance, and the regular report may be automatically transmitted to the transmission destination.

[0062] Next, the flow of processing from a transportation means proposal request to a proposal will be described. FIG. 11 is a sequence diagram showing the flow of processing from referring to transportation records and requesting a transportation means proposal to a proposal in the CO2 emission management system 100. When a user on the shipper terminal 15 performs an operation to refer to transportation records on the shipper terminal 15, a transportation record reference request is sent to the CO2 emission management device 10 (step S501). At this time, the user on the shipper terminal 15 specifies, for example, "the current carbon dioxide emission amount is equal to or greater than a certain value." When the CO2 emission management device 10 receives the transportation record reference request, it extracts transportation record data corresponding to "the current carbon dioxide emission amount is equal to or greater than a certain value" included in the transportation record reference request from the DB 108 (step S502), and sends it to the shipper terminal 15 (step S503).

[0063] The user on the shipper terminal 15 side refers to the transport performance data received by the shipper terminal 15 and grasps the projects whose current carbon dioxide emissions are equal to or greater than a certain value. It is preferable that the user on the shipper terminal 15 side cannot refer to detailed transport means (stopovers, prime movers, etc.). In this way, the privacy of the transport business operator side is maintained. Then, when the user on the shipper terminal 15 side specifies a specific project (transport route) and performs an operation to request a proposal of a transport means for reducing CO2 emissions on the transport route, a proposal request is sent to the CO2 emission management device 10 (step S51). The proposal request is received by the request reception unit 105 of the CO2 emission management device 10. In this embodiment, the transport route can be specified by specifying the project and the period. The proposal request includes the "project name", "period (start date and time, end date and time)", etc., as shown in FIG. 7(D). In addition to the "project name", the transport route may be specified by a "tag". It is also possible to refer to the transport performance without specifying the period (or by specifying the entire period).

[0064] 11, when the CO2 emission management device 10 receives the proposal request, it notifies the transport company terminal 20 of the transport company in charge of the project that it has received the proposal request (step S52). This notification specifies information such as the name of the shipper who sent the proposal request and the project (transportation route) included in the proposal request.

[0065] When the transport company terminal 20 is notified that the proposal request has been received and the user of the transport company operates the transport company terminal 20 to instruct the transport company to search for a transport means for reducing CO2 emissions on the transport route specified in the proposal request, the transport company terminal 20 transmits a search request to the CO2 emission management device 10 (step S53). This search request specifies information such as the project (transport route) included in the proposal request.

[0066] When the CO2 emission management device 10 receives a search request, the search unit 106 of the CO2 emission management device 10 refers to the map information and the information on the transportation network stored in the DB 108, and searches for other transportation means in the project (transportation route) specified in the search request. The search unit 106 searches for other transportation means by using existing search algorithms such as depth-first search, breadth-first search, Dijkstra's algorithm, etc.

[0067] For example, for the transportation route from the departure point "AAA" to the destination "BBB" of project A, the search unit 106 may search for other transportation means as the other transportation means. In this case, since the current transportation means of project A is "truck", the search unit 106 searches whether there is a route in which other transportation means can be used for the transportation route from the departure point "AAA" to the destination "BBB". Here, it is assumed that the search unit 106 has found a route that can use trucks from the departure point "AAA" to the destination "CCC" by passing through the destination "CCC" and railroads from the destination "CCC" to the destination "BBB". In this case, the proposal unit 107 estimates the CO2 emissions related to the transportation means "truck + railroad" in the discovered route by using a CO2 emission calculation formula, and judges whether the estimated CO2 emissions are smaller than the current CO2 emissions by comparing (step S55). Then, if the proposal unit 107 determines that the estimated CO2 emissions are smaller than the current CO2 emissions, it designates the transportation means "truck + train" on the discovered route as another transportation means for reducing CO2 emissions in the result output response and transmits it to the transportation company terminal 20 (step S56).

[0068] The search unit 106 may also search for other motor vehicle types as other means of transportation. In this case, since the current means of transportation of the project A is "truck" and the motor vehicle type is "diesel vehicle", the search unit 106 searches for other motor vehicle types "gasoline vehicle", "HV vehicle", "EV vehicle", and "fuel cell vehicle". Then, the proposal unit 107 estimates and compares the CO2 emissions for each of the "gasoline vehicle", "HV vehicle", "EV vehicle", and "fuel cell vehicle" using an appropriate CO2 emission calculation formula, and determines that the CO2 emissions when the "fuel cell vehicle" is used are smaller than the current CO2 emissions (step S55). In this case, the proposal unit 107 designates the "fuel cell vehicle" as a motor vehicle type for reducing CO2 emissions in the result output response and transmits it to the transport company terminal 20 (step S56).

[0069] Also, for example, the search unit 106 may search for other fuels as other means of transportation. In this case, since the current means of transportation of the project A is "truck", the type of motor vehicle is "diesel vehicle", and the type of fuel is "diesel", the search unit 106 searches for other types of fuels "gasoline", "LP gas", "natural gas", "synthetic fuel", and "biofuel". Then, the proposal unit 107 estimates and compares the CO2 emissions for each of "gasoline", "LP gas", "natural gas", "synthetic fuel", and "biofuel" using an appropriate CO2 emission calculation formula, and determines that the CO2 emissions when "natural gas" is used are smaller than the current CO2 emissions (step S55). In this case, the proposal unit 107 designates "natural gas" as another type of fuel for reducing CO2 emissions in the result output response and transmits it to the transport company terminal 20 (step S56).

[0070] When the transport company terminal 20 receives the result output response, a search result screen as shown in the example of FIG. 12 is displayed on the display 40 of the transport company terminal 20. On the search result screen, first, information on the current project is displayed in the current project display field 402. On the search result screen, the contents of the proposals "Proposal 1", "Proposal 2", and "Proposal 3" made by the proposal unit 107 of the CO2 emission management device 10 are displayed, and the user can select them by checking the boxes. On the search result screen, the CO2 emission amount in the current project, the CO2 emission amount by each of the proposals 1 to 3, and the CO2 emission amount that can be reduced by each of the proposals 1 to 3 are displayed. When the user on the transport company side selects a desired proposal by checking the boxes and presses the button for creating a proposal, the transport company terminal 20 transmits a proposal creation request specifying the contents selected by the user to the CO2 emission management device 10 (step S57). On the search result screen, the economic costs when the proposals 1 to 3 are adopted may be calculated and displayed. Furthermore, the proposals 1 to 3 may be displayed in order of the amount of CO2 reduction or in order of the economic costs. This allows users on the shipper terminal side to select alternatives based on the amount of CO2 reduction and economic cost.

[0071] When the CO2 emission management device 10 receives the proposal creation request, it creates a proposal related to the proposal specified in the proposal creation request (step S58). Then, the CO2 emission management device 10 transmits the created proposal to the shipper terminal 15 of the shipper (step S59). Note that the proposal may be transmitted to the transport company terminal 20, and then transmitted to the shipper terminal 15 from the transport company terminal 20 or the CO2 emission management device 10 after confirmation work. The user on the shipper terminal 15 side can consult about reducing CO2 emissions based on the proposal, and the effect of reducing CO2 emissions can be expected. In addition, as a practical matter, changing the transportation means may incur more costs than the current situation, so there is a possibility that financial assistance from the transportation company side will be required. By presenting the costs related to the alternative plan in the proposal, the effect of facilitating consultation can be expected. In addition, there is also an advantage that the transportation company can propose improvements without disclosing the current detailed transportation means.

[0072] The display example in Fig. 12 is just an example, and any combination of changes in transportation means, vehicle type by engine, and fuel may be used. In this embodiment, the proposal is sent from the transport company terminal 20 to the shipper terminal 15 via the system, but the transport company may output the proposal and submit it to the shipper by email, hand delivery, or the like.

[0073] Various embodiments and modifications of the present disclosure are possible without departing from the broad spirit and scope of the present disclosure. The above-described embodiments are for explaining the present disclosure and do not limit the scope of the present disclosure. That is, the scope of the present disclosure is indicated by the claims, not the embodiments. Various modifications made within the scope of the claims and the scope of the disclosure equivalent thereto are considered to be within the scope of the present disclosure.

[0074] Access rights may be set for other transport companies, shippers, etc., so that transport route information and transport performance information can be shared with other users such as other transport companies and shippers. Information may be shared on a project-by-project basis, a period-by-period basis, a tag-by-tag basis, etc. In this case, the transport performance may be made available for viewing, editing, and periodic report acquisition from the transport company terminal 20 of the transport company with whom the information is shared, or the shipper terminal 15 of the shipper with whom the information is shared. In this way, the sharer can view and edit the CO2 emission amount and acquire periodic reports, improving the convenience of the CO2 emission management system. [Explanation of symbols]
