Description

Carbon dioxide emission calculation method, carbon dioxide emission calculation system and program

[0001] The present invention relates to a technique that is effective for calculating the amount of carbon dioxide emitted during transportation in physical distribution.

[0002] In logistics, there is a demand for technology that visualizes carbon dioxide emissions. For example, International Organization for Standardization (ISO) 14083, published in 2023, proposes calculating the carbon dioxide emissions generated for each product across all transportation means and hub sections. For example, Patent Document 1 discloses a technology for calculating the carbon dioxide emissions associated with the transportation of goods upstream in a supply chain.

[0003] JP 2016-126372 A

[0004] However, for example, in supply chains that include overseas destinations, the amount of carbon dioxide emissions has not yet been refined. This is because, while Patent Document 1 allows for a certain degree of calculation of carbon dioxide emissions depending on transportation methods such as rail and air, it does not take into account, for example, sea routes such as North American routes, European routes, and Japan-China routes, cargo types, ship sizes, etc., and therefore does not allow for a more precise calculation of carbon dioxide emissions. For example, in transportation, small ships may be used to pass through canals such as the Suez Canal, and a more precise calculation is required when using such ships.

[0005] The present invention aims to provide a carbon dioxide emission calculation method, a carbon dioxide emission calculation system, and a program that can more precisely calculate the amount of carbon dioxide emissions associated with transportation based on the route, cargo type, etc.

[0006] The present invention provides a carbon dioxide emission calculation method executed by a computer to calculate the amount of carbon dioxide emitted during transportation in logistics, which includes: an acquisition step of acquiring transportation data related to the departure date, arrival date, loading point, unloading point, sea route, cargo type, and ship type for transportation by a specified shipper; and a calculation step of applying a specified carbon dioxide emission calculation model based on the transportation data to calculate the amount of carbon dioxide emissions for the transportation.

[0007] According to the present invention, when calculating the amount of carbon dioxide emissions during transportation in logistics, by taking into account the departure date, arrival date, loading point, unloading point, sea route, cargo type, ship type, etc., it is possible to calculate the amount of carbon dioxide emissions related to transportation more precisely based on the sea route, cargo type, etc.

[0008] Although the present invention is in the category of a method, the same functions and effects specific to the category can be achieved even when it is applied to a system or a program.

[0009] According to the present invention, it is possible to more precisely calculate the amount of carbon dioxide emissions associated with transportation based on the shipping route, cargo type, etc.

[0011] DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings. In the following drawings, the same elements are designated by the same numbers or symbols throughout the description of the embodiments.

[0012] [Outline of Carbon Dioxide Emission Calculation System 1] Fig. 1(a) is a block diagram illustrating an outline of the carbon dioxide emission calculation system 1, and Fig. 1(b) is a diagram illustrating a computer 10. The components of the carbon dioxide emission calculation system 1 will be described with reference to Fig. 1. The carbon dioxide emission calculation system 1 is a system that calculates the amount of carbon dioxide emitted during transportation in logistics, and includes the computer 10. The computer 10 includes, for example, a processor; an acquisition unit that acquires transportation data related to the departure date (date, time, etc.), arrival date (date, time, etc.), loading location (loading port, loading country, etc.), discharge location (discharge port, discharge country, etc.), sea route (European route, North American route, daytime route, etc.), cargo type (container, bulk, etc.), and ship type (general cargo ship that transports containers, finished product transport ship that transports finished products such as machinery and vehicles, bulk carrier (ro-ro (roll-on roll-off) ship, etc.)) for a specified shipper's transportation; a calculation unit that applies a predetermined carbon dioxide emission calculation model to calculate the carbon dioxide emissions of the transportation based on the transportation data; an output unit that outputs the carbon dioxide emissions for a specified period for each shipper; and a selection unit that selects the transportation route. The carbon dioxide emission calculation system 1 may be implemented using a single computer or multiple computers, such as a cloud computer. In this specification, a cloud computer may refer to either a computer that uses any computer in a scalable manner to perform a specific function, or a computer that includes multiple functional modules to realize a system and uses the functions in any combination.

[0013] This computer 10 executes each process executed by the carbon dioxide emission calculation system 1. The computer 10 has a data storage unit such as a hard disk, semiconductor memory, recording medium, memory card, etc. as a recording unit. The computer 10 has various devices, etc. as a processor, that execute various processes. The computer 10 is connected to the core system 2 and information terminals 3 via a network such as a public line network or an intranet.

[0014] The core system 2 is a system managed by the shipper, and outputs cargo shipping instructions and the like to a WMS (Warehouse Management System) (not shown), and also holds transportation data related to the shipper's transportation, such as departure date, arrival date, loading point, unloading point, sea route, cargo type, ship type, etc. The WMS may be any system that has functions such as general warehouse entry / exit management and inventory management.

[0015] The information terminal 3 is a terminal device managed by an administrator of the carbon dioxide emission calculation system 1, and is, for example, a mobile phone, a smartphone, a tablet terminal, a personal computer, or a laptop computer. Note that the administrator who operates the information terminal 3 in this specification may be an administrator who manages the system, or may be an operator corresponding to the shipper.

[0016] 1, carbon dioxide emission calculation system 1 is a system that calculates the amount of carbon dioxide emission emitted during transportation in logistics, and at least a computer 10 is connected to a core system 2 and an information terminal 3 so as to be able to communicate data via a network such as a public line network or an intranet. Note that the components of carbon dioxide emission calculation system 1 are merely examples, and the number, types, and functions of terminals, devices, and other equipment not shown can be changed as appropriate.

[0017] The computer 10 includes, as a processor, a CPU (Central Processing Unit), a GPU (Graphics Processing Unit), a RAM (Random Access Memory), a ROM (Read Only Memory), etc., and, as a communication unit, a device for enabling communication with other terminals and devices, an acquisition unit for acquiring transportation data regarding the departure date, arrival date, loading port, unloading port, route, cargo type, and ship type for transportation of a specified shipper, an output unit for outputting carbon dioxide emissions for a specified period for each shipper, etc. The computer 10 also includes, as a processing unit, a device for executing various processes, a calculation unit for calculating carbon dioxide emissions for transportation by applying a specified carbon dioxide emission calculation model based on the transportation data, a selection unit for selecting a transportation route, etc.

[0018] An outline of the processing steps performed by the carbon dioxide emission calculation system 1 when calculating the amount of carbon dioxide emitted during transportation in physical distribution will be described with reference to FIG.

[0019] The computer 10 acquires transportation data relating to the departure date, arrival date, loading location, unloading location, sea route, cargo type, and ship type for a specific shipper's transportation (step S1). The computer 10 acquires this transportation data from the shipper's core system 2.

[0020] The computer 10 calculates the carbon dioxide emissions for transportation by applying a predetermined carbon dioxide emissions calculation model based on the transportation data (step S2). The computer 10 calculates the carbon dioxide emissions for transportation based on the acquired transportation data by applying the carbon dioxide emissions calculation model set by the administrator of the carbon dioxide emissions calculation system 1. For example, the computer 10 calculates the carbon dioxide emissions for transportation by multiplying the transported weight (t), the transport distance (km), and the carbon dioxide emissions intensity.

[0021] The computer 10 outputs the amount of carbon dioxide emission (step S3). The computer 10 outputs the calculated amount of carbon dioxide emission to the information terminal 3, and causes the information terminal 3 to display the amount of carbon dioxide emission.

[0022] An overview of the processing steps when the carbon dioxide emission calculation system 1 calculates the amount of carbon dioxide emission emitted during transportation in physical distribution in steps S1 to S3 will be described with reference to Fig. 2. Fig. 2 is a flowchart showing the carbon dioxide emission calculation process executed by the computer 10.

[0023] The computer 10 acquires transportation data related to the departure date, arrival date, loading location, unloading location, sea route, cargo type, and ship type for a specific shipper's transportation (step S10). The transportation data may include the departure date (date, time, etc.), arrival date (date, time, etc.), loading location (loading port, loading country, etc.), unloading location (unloading port, unloading country, etc.), sea route (European route, North American route, daytime route, etc.), cargo type (container, bulk, etc.), ship type (general cargo ship transporting containers, finished product transport ship transporting finished products such as machinery and vehicles, bulk carrier (ro-ro ship, etc.)), as well as other data (ship size, weight, transportation means, private / contracted transportation, transportation mode, etc.) (see Figure 3). The transportation data will be described with reference to Figure 3. Figure 3 is a diagram schematically illustrating an example of transportation data. Figure 3 shows transportation data 20. The transportation data 20 includes the departure date, arrival date, loading country, loading port, discharge country, discharge port, sea route, cargo type, ship type, ship size, weight, transportation means, private / consigned transport, and transportation mode. The departure date is the date (year, month, day, etc.) when the cargo departs from the loading port. The arrival date is the date (year, month, day, etc.) when the cargo arrives at the discharge port. The loading country is the name of the country where the cargo is loaded. The loading port is the name of the port where the cargo is loaded (the name of the place where the port is located, the name of the port, etc.). The discharge country is the name of the country where the cargo is discharged. The discharge port is the name of the port where the cargo is discharged (the name of the place where the port is located, the name of the port, etc.). The sea route is the route used by ships and other vessels to navigate on the sea or river when transporting cargo, and is, for example, a European route, a North American route, a Japan-China route, etc. The cargo type is the type of cargo, such as container cargo or bulk cargo. Ship type includes general cargo ships that transport containers, finished product transport ships that transport finished products such as machinery and vehicles, bulk carriers (ro-ro ships, etc.), etc. Ship size includes the number of containers to be loaded (TEU (Twenty-foot Equivalent Units)) or gross weight (dwt (Dead Weight)). Weight is the weight of the cargo to be loaded. Transport means is the method used to transport the cargo, such as ship, truck, rail, or airplane. Private / consignment transport refers to whether the transport is carried by the company itself or by a contractor other than the company.The transportation mode may be FCL (Full Container Load), LCL (Less Than Container Load), etc. The computer 10 acquires this transportation data from the core system 2. The computer 10 may acquire any one piece of transportation data, or may acquire multiple pieces of transportation data. The core system 2 transmits the transportation data to the computer 10 based on a request from the computer 10, input from an operator of the core system 2 (such as an administrator of the core system 2), etc. The computer 10 receives this transportation data and acquires transportation data related to the departure date, arrival date, loading port, unloading port, route, cargo type, and ship type for transportation by a specified shipper. The computer 10 performs data cleansing when acquiring this transportation data from the shipper. This data cleansing is performed to ensure consistency between the acquired transportation data and the data to be registered in preset items. As an example of data cleansing, if the data to be registered for the loading point or unloading point is a city name, and the loading point or unloading point in the acquired transportation data is not a city name (for example, if it is location information such as latitude and longitude, or an address), the computer 10 changes the loading point or unloading point to a city name.The computer 10 also appropriately converts the acquired transportation data other than the loading point or unloading point to match the content of the data to be registered in the predetermined items.The method by which the computer 10 cleanses the transportation data may, for example, refer to a database (DB) in which the types of data to be registered and their contents are registered in advance, may convert the data based on a predetermined conversion method, or may appropriately execute other methods.

[0024] The computer 10 calculates the amount of carbon dioxide emissions from transportation by applying a predetermined carbon dioxide emission calculation model based on the transportation data (step S11). The carbon dioxide emission calculation model allows the administrator to set a carbon dioxide emission intensity factor that includes at least one of the following: means of transportation (ship, truck, rail, airplane, etc.), loading location (loading port, loading country), unloading location (unloading port, unloading country), sea route (European route, North American route, Japan-China route, etc.), cargo type (container, bulk, etc.), and ship type (general cargo ship, finished product transport ship, bulk carrier, etc.), and a calculation formula that includes this carbon dioxide emission intensity factor.

[0025] Here, the carbon dioxide emission intensity will be explained. Hereinafter, the carbon dioxide emission intensity will also be simply referred to as the intensity. The intensity is the amount of carbon dioxide emissions per unit of economic activity, for example, the amount of carbon dioxide emissions per ton-kilometer of cargo transported. The intensity varies depending on the means of transport, both in terms of granularity and the customer data from which it is selected. The granularity and customer data for each means of transport will be explained. First, a case will be explained where the means of transport is a ship. The granularity for a ship is the trade lane (the sea route connecting the departure and arrival points) and the ship type. When the granularity is the trade lane, the customer data is the departure and arrival points. When the granularity is the ship type, the customer data is product data and classification. Next, a case will be explained where the means of transport is a truck. The granularity for a truck is the vehicle size, loading rate, vehicle type, and legal standards. When the granularity is the vehicle size, the customer data is weight. When the granularity is the loading rate, the customer data is weight. When the granularity is the vehicle type, the customer data is product data and classification. Furthermore, when the granularity is a legal standard, the customer data is the departure and arrival points. Next, we will explain the case where the means of transportation is railways. The granularity for railways is the power source and legal standard. When the granularity is the power source, the customer data is the departure and arrival points. When the granularity is a legal standard, the customer data is the departure and arrival points. Finally, we will explain the case where the means of transportation is aircraft. The granularity for aircraft is the aircraft type, distance, and standard. When the granularity is aircraft type, the customer data is the departure and arrival points. When the granularity is distance, the customer data is the departure and arrival points. When the granularity is standard, the customer data is data determined by customer requests.

[0026] The unit consumption varies depending on the organization (such as an international organization) that negotiates the unit consumption. For example, unit consumption provider A (hereinafter simply referred to as "Institution A") provides unit consumption data for ships. Institution A collects primary data on carbon dioxide emissions from carriers (such as shipping companies) and calculates a common unit consumption data using its own method. Institution A's unit consumption data differs between the unit consumption data for room-temperature transport and the unit consumption data for refrigerated transport. Institution A publishes the calculated unit consumption data for each trade lane (see Figure 4). The computer 10 obtains this unit consumption data using a predetermined API (Application Programming Interface) or the like and uses it to calculate carbon dioxide emissions. In this case, the unit consumption data increases as the distance (km) of the route taken to transport the cargo increases, and the unit consumption data for refrigerated transport is greater than the unit consumption data for room-temperature transport.

[0027] Figure 4 is a diagram showing an example of unit consumption data provided by engine A. Table 21 is shown in the figure. Table 21 shows some of the unit consumption data for each trade lane's departure and arrival points. Table 21 shows the unit consumption data for each trade lane's departure and arrival points, including the unit consumption data for normal temperature transport by general cargo ships and the unit consumption data for refrigerated transport by general cargo ships. Computer 10 uses these unit consumption data to calculate the carbon dioxide emissions.

[0028] Furthermore, a unit consumption data providing organization B (hereinafter simply referred to as organization B) provides an API that calculates unit consumption data based on information on departure and arrival points, the means of transportation, and other optional information. The computer 10 uses this API to calculate carbon dioxide emissions. An example will be described in which the computer 10 calculates each unit consumption data for each means of transportation using the API provided by organization B.

[0029] First, a case where the means of transportation is a ship will be described. The computer 10 selects three routes for each trade lane. For example, for the trade lane between Northern Europe and the East Coast of North America and the Gulf of Mexico, three routes are selected: Rotterdam-New York (Route 1), Antwerp-Savannah (Route 2), and Hamburg-Houston (Route 3). For each route (Route 1 to Route 3), the computer 10 makes a request to the API provided by engine B and obtains the respective basic units. The computer 10 does not specify a detailed ship type, but makes the request using engine B's default ship type. For each route, the computer 10 obtains four basic units: general cargo ship, finished product carrier, bulk carrier (less than 5,000 dwt (dead weight)), and bulk carrier (5,000 dwt or more). The computer 10 calculates the average value of the basic unit for each ship type for the three routes and uses the calculated average value as the basic unit for each ship type for the trade lane. In this case, the basic unit becomes larger as the distance (km) of the route when transporting cargo and the weight of the ship type become larger.

[0030] FIG. 5 is a diagram schematically illustrating an example of each unit consumption calculated using the API provided by Institution B. Table 22 is shown in the figure. Table 22 shows some of the unit consumption values ​​for each trade lane's origin and destination. Table 22 shows four types of unit consumption values ​​for each trade lane's origin and destination based on ship type (general cargo ship, finished product transport ship, bulk carrier (less than 5000 dwt (dead weight)), bulk carrier (5000 dwt or more)). Computer 10 calculates carbon dioxide emissions using these unit consumption values. Note that when calculating carbon dioxide emissions for general cargo ships, computer 10 preferably uses the unit consumption values ​​shown in Table 21 shown in FIG. 4, and when calculating carbon dioxide emissions for other ships (finished product transport ships, bulk carriers), computer 10 preferably uses the unit consumption values ​​shown in Table 22 shown in FIG. 5.

[0031] Next, a case where the transportation means is a truck will be described. The computer 10 selects three transportation routes (origin and destination) for each of three predetermined criteria, such as US, EU, and JP. For example, based on the JP criteria, three routes are selected: Tokyo-Osaka (Route 1), Tokyo-Sendai (Route 2), and Osaka-Hakata (Route 3). For each route, the computer 10 makes a request to the API provided by the institution B based on a combination of the route and predetermined parameters (vehicle size, loading rate, vehicle type, etc.) and obtains the respective basic units. For each route, the computer 10 obtains the basic units for the number of combinations of the route and the predetermined parameters. For each combination of the route and the predetermined parameters, the computer 10 calculates the average basic unit for the three routes and uses the calculated average as the basic unit for the combination of the reference route and the predetermined parameters. In this case, the basic unit becomes larger the longer the distance (km) of the route when transporting the cargo and the heavier the vehicle type.

[0032] FIG. 6 is a diagram showing an example of each unit of consumption calculated using an API provided by institution B. Table 23 is shown in the figure. Table 23 shows some of the units of consumption for each standard. In table 23, the units of consumption for each standard are shown as units of consumption according to vehicle type for each vehicle class according to size (vehicle class preset for each predetermined size). Computer 10 uses these units of consumption to calculate the carbon dioxide emissions.

[0033] FIG. 7 is a diagram showing an example of each unit consumption calculated using an API provided by engine B. Table 24 is shown in the figure. Table 24 shows some of the units consumption for each standard. In table 24, the units consumption for each standard are shown as units consumption according to vehicle type and loading rate for each vehicle class according to size (vehicle class preset for each specified size). Computer 10 uses these units consumption to calculate the carbon dioxide emissions.

[0034] Next, a case where the transportation means is rail will be described. The computer 10 selects four transportation routes (origin and destination) based on two predetermined standards, such as the US and the EU. For example, based on the EU standard, four routes are selected: Shanghai-Ulaanbaatar (Route 1), Ulaanbaatar-Moscow (Route 2), Moscow-Hamburg (Route 3), and Hamburg-Shanghai (Route 4). For each route, the computer 10 makes a request to the API provided by institution B based on a combination of the route and predetermined parameters (vehicle type (railroad), power source, vehicle type (truck), legal standards, etc.) and obtains the respective basic units. For each route, the computer 10 obtains the basic units for the number of combinations of the route and the predetermined parameters. For each combination of the route and the predetermined parameters, the computer 10 calculates the average basic unit for the four routes and uses the calculated average as the basic unit for each combination of the standard route and the predetermined parameters. In this case, the basic unit becomes larger as the distance (km) of the route along which the cargo is transported becomes longer.

[0035] FIG. 8 is a diagram showing an example of each unit consumption calculated using the API provided by the organization B. In the figure, a table 25 is shown. The table 25 shows some of the unit consumptions for each standard. In the table 25, the unit consumptions for each standard are shown as unit consumptions corresponding to the power source. The computer 10 uses these unit consumptions to calculate the carbon dioxide emissions.

[0036] Finally, a case where the means of transportation is an aircraft will be described. The computer 10 selects four transportation routes (origin and destination) in increments of air distance, such as 0 km-500 km, 500 km-1000 km, 1000 km-2000 km, 2000 km-3700 km, and distances longer than 3700 km. For example, for air distances longer than 3700 km, four routes are selected: Los Angeles-New York (Route 1), New York-London (Route 2), Tokyo-Los Angeles (Route 3), and London-Shanghai (Route 4). For each route, the computer 10 makes a request to the API provided by institution B based on a combination of the route and predetermined parameters (standards, aircraft type, etc.) and obtains the basic unit for each route. For each route, the computer 10 obtains the basic unit for the number of combinations of the route and the predetermined parameters. The computer 10 calculates the average value of the basic unit for each of the four routes for the combination of each route and the predetermined parameter, and uses the calculated average value as the basic unit for the combination of the reference route and the predetermined parameter. In this case, the basic unit becomes larger as the distance (km) of the route when transporting the cargo becomes shorter.

[0037] FIG. 9 is a diagram schematically illustrating an example of each unit consumption calculated using the API provided by organization B. A table 26 is shown in the figure. The table 26 shows some of the units consumption for each aircraft type. In the table 26, the units consumption for each aircraft type are shown in accordance with applicable laws and regulations. The computer 10 uses these units consumption to calculate the carbon dioxide emissions.

[0038] A method for setting a carbon dioxide emission calculation model will be described with reference to FIG. 10 . FIG. 10 is a diagram schematically illustrating a setting screen for the carbon dioxide emission calculation model. FIG. 10 illustrates a setting screen 30. The setting screen 30 is displayed on the display portion of the information terminal 3. Note that the display of the setting screen 30 is not limited to the information terminal 3, but may also be displayed on another terminal device capable of communicating with the computer 10. On the setting screen 30, setting icons 31 to 33 are displayed on the screen. The administrator 34 inputs information into each of the setting icons 31 to 33 to set the basic unit and the calculation formula including the basic unit. Each icon is linked to the icons before and after it (for example, setting icon 32a and setting icon 33a in the case of setting icon 31). The setting icon 31 is used to perform various settings and data deletion required for data cleansing. These various settings and data deletion include, for example, setting the fiscal year for which carbon dioxide emissions are to be calculated and deleting data unnecessary for calculating carbon dioxide emissions from the transportation data for the set fiscal year. The setting icons 32 (32a-c) are used to perform various settings when the means of transportation is rail. The setting icons 33 (33a-c) are used to perform various settings when the means of transportation is a ship. The setting icons 31-33 may be displayed on the screen from the beginning, or may be newly displayed as a result of the administrator 34 of the carbon dioxide emission calculation system 1 performing an input operation on the setting icons 31-33. For example, when the administrator 34 performs an input operation on the setting icon 31, new setting icons 32a, 33a corresponding to this setting icon 31 are displayed. Similarly, when the administrator 34 performs an input operation on the previous setting icons for the setting icons 32b-c and the setting icons 33b-c, new setting icons corresponding to the setting icons for which the input operation was performed are sequentially displayed.The administrator 34 inputs data to the setting icons 31 on the computer 10 to perform various settings and data deletion required for data cleansing (e.g., selecting transportation data for the year for which the administrator 34 desires to calculate carbon dioxide emissions, deleting unnecessary data from the transportation data, etc.). The administrator 34 inputs data to the setting icons 33a on the computer 10 to set that the means of transportation is a ship. The administrator 34 inputs data to the setting icons 33b on the computer 10 to set various values ​​required for calculating carbon dioxide emissions (e.g., setting a predetermined fixed value, setting a mode, setting a carbon dioxide emission calculation method, setting a data type, etc.). The administrator 34 inputs data to the setting icons 33c on the computer 10 to set a calculation formula for calculating carbon dioxide emissions. The computer 10 sets a carbon dioxide emission calculation model using this setting screen 30 and calculates carbon dioxide emissions by applying the set carbon dioxide emission calculation model. The content set using s on each setting icon is the setting of the basic unit and the calculation formula including the basic unit.

[0039] A method for selecting a basic unit used by the computer 10 when calculating carbon dioxide emissions will be described. First, a case will be described where the means of transport is a ship. In this case, the setting screen 30 shown in FIG. 10 above indicates that the means of transport is a ship. When a general cargo ship is set, the computer 10 selects different types of basic units depending on whether the transport is at room temperature or refrigerated. At this time, in the case of a general cargo ship, the computer 10 preferably uses the basic unit provided by engine A. When a general cargo ship and normal temperature transport are set, the computer 10 selects one of the basic units corresponding to the normal temperature transport column in table 21 shown in FIG. 4 above, which corresponds to the trade lane and departure and arrival points for which the current carbon dioxide emissions are to be calculated based on the transportation data. Furthermore, when a general cargo ship and refrigerated transport are set, the computer 10 selects one of the basic units corresponding to the refrigerated transport column in table 21 shown in FIG. 4 above, which corresponds to the trade lane and departure and arrival points for which the current carbon dioxide emissions are to be calculated based on the transportation data. When a finished product transport ship is set, the computer 10 selects a basic unit corresponding to the trade lane and departure and arrival points for which current carbon dioxide emissions based on the transport data are to be calculated from among the basic units corresponding to the column for finished product transport ship in the table 22 shown in Figure 5 described above. When a bulk carrier is set, the computer 10 selects a basic unit depending on whether the dwt is less than 5,000 or 5,000 or more. When a bulk carrier and a vessel size of less than 5,000 dwt is set, the computer 10 selects a basic unit corresponding to the trade lane and departure and arrival points for which current carbon dioxide emissions based on the transport data are to be calculated from among the basic units corresponding to the column for bulk carrier < 5 kdwt in the table 22 shown in Figure 5 described above. When a bulk carrier and a vessel size of 5,000 dwt or more is set, the computer 10 selects a basic unit corresponding to the trade lane and departure and arrival points for which current carbon dioxide emissions based on the transport data are to be calculated from among the basic units corresponding to the column for bulk carrier >= 5 kdwt in the table 22 shown in Figure 5 described above.

[0040] Next, a case where the transportation means is a truck will be described. In this case, the transportation means is set to be a truck on the setting screen 30 shown in FIG. 10 described above. When the truck setting is selected, the computer 10 selects different types of basic units depending on whether or not the loading rate is considered. The computer 10 selects the region where the transportation will occur based on the transportation data. For example, the computer 10 selects US for the United States and Canada, selects JP for Japan, and selects EU for other countries. The computer 10 selects a vehicle type based on the transportation data. For example, the computer 10 selects a curtainsider or a general truck for general goods, a trailer or a 2TEU trailer for containers, a refrigerated or frozen truck for refrigerated or frozen goods, a tanker truck for liquid goods, and a truck carrier for finished vehicles. The computer 10 estimates the vehicle class from the transportation data and estimates and selects the class of the truck to be used for transportation. The computer 10 selects the unit of measure corresponding to the vehicle class for which current carbon dioxide emissions are to be calculated based on the transportation data from among the units of measure corresponding to the selected vehicle class in the table 23 shown in Figure 6. Furthermore, when the loading rate is taken into consideration, the computer 10 calculates the loading rate (10%, 20%, 40%, 60%, 80%, 100%) from the estimated vehicle class, and selects the unit of measure corresponding to the vehicle class and loading rate for which current carbon dioxide emissions are to be calculated based on the transportation data from among the units of measure corresponding to the selected vehicle class and calculated loading rate in the table 24 shown in Figure 7.

[0041] Next, a case where the means of transportation is railroad will be described. In this case, railroad is set as the means of transportation on the setting screen 30 shown in FIG. 10 described above. When railroad is set, the computer 10 selects a unit of consumption depending on which power source is to be used. The computer 10 selects the region where transportation occurs based on the transportation data. For example, the computer 10 selects "US" for the United States and Canada, and selects "EU" for countries other than the United States and Canada excluding Japan. Note that when Japan is selected, the computer 10 selects a unit of consumption provided by ELP (Environmental Load Point). The computer 10 selects a power source based on the transportation data. The computer 10 selects a unit of consumption corresponding to the power source for which carbon dioxide emissions are to be calculated based on the transportation data, from among the units of consumption corresponding to the selected power source column in the table 25 shown in FIG. 8 described above.

[0042] Finally, a case where the means of transportation is an aircraft will be described. In this case, the means of transportation is set to an aircraft on the setting screen 30 shown in FIG. 10 described above. When the aircraft is set, the computer 10 selects a basic unit depending on which standard is used. The computer 10 selects an aircraft type based on the distance between departure and arrival points based on the transportation data. For example, the computer 10 selects an aircraft type when the distance is less than 500 km, 500 km or more but less than 1,000 km, 1,000 km or more but less than 3,700 km, or 3,700 km or more. The computer 10 selects a basic unit corresponding to the standard column in the table 26 shown in FIG. 9 described above, that corresponds to the selected aircraft type and standard for which carbon dioxide emissions are to be calculated based on the transportation data.

[0043] A specific example of how the computer 10 calculates carbon dioxide emissions will be described. The computer 10 calculates the carbon dioxide emissions (g-CO2) by multiplying the transport weight (t), the transport distance (km), and the carbon dioxide emissions intensity (g-CO2 / t km) (carbon dioxide emissions = transport weight × transport distance × carbon dioxide emissions intensity). Here, the transport weight is the weight of the cargo to be transported. The transport distance is the distance the cargo is transported. In other words, the carbon dioxide emissions are values ​​that depend on the weight of the cargo and the transport distance. The carbon dioxide emissions intensity is selected by the selection method described above. When calculating the carbon dioxide emissions, the computer 10 calculates the product of the carbon dioxide emissions intensity, the transport weight, and the transport distance. Therefore, the larger the transport weight, the larger the carbon dioxide emissions, and the longer the transport distance, the larger the carbon dioxide emissions. The computer 10 can also be configured to take into account the transport speed (knots) when calculating the carbon dioxide emissions. In this case, the faster the transport speed, the larger the carbon dioxide emissions. This transport speed may be an average value of the transport speed during transport, or may be the maximum speed or the minimum speed.

[0044] The computer 10 outputs the amount of carbon dioxide emission (step S12). The computer 10 transmits the calculated amount of carbon dioxide emission to the information terminal 3. The information terminal 3 displays the amount of carbon dioxide emission on its own display unit via a predetermined UI (User Interface). The computer 10 outputs the amount of carbon dioxide emission by displaying the amount of carbon dioxide emission on the information terminal 3.

[0045] An overview of a first modified example of the processing steps when the carbon dioxide emission calculation system 1 calculates the amount of carbon dioxide emission emitted during transportation in physical distribution in steps S1 to S3 will be described with reference to Fig. 11. Fig. 11 is a diagram showing a flowchart of a first modified example of the carbon dioxide emission calculation process executed by the computer 10. In the first modified example, the computer 10 calculates the amount of carbon dioxide emission for all transportation during a predetermined period (e.g., each fiscal year). Note that detailed explanations of processes similar to those described above will be omitted.

[0046] The computer 10 acquires transportation data related to all departure dates, arrival dates, loading locations, unloading locations, sea routes, cargo types, and ship types for a specified period of time for transportation by a specified shipper (step S20). The transportation data is the same as that in step S10 described above. The computer 10 acquires this transportation data from the core system 2. The computer 10 acquires all transportation data corresponding to the specified period entered by the administrator. The core system 2 transmits all transportation data for the specified fiscal year to the computer 10 based on a request from the computer 10 or input from the operator of the core system 2 (such as the administrator of the core system 2). The computer 10 receives this transportation data and acquires transportation data related to all departure dates, arrival dates, loading locations, unloading locations, sea routes, cargo types, and ship types for a specified period of time for transportation by a specified shipper. The computer 10 performs data cleansing when acquiring this transportation data from the shipper. This data cleansing is the same as the data cleansing in step S10 described above.

[0047] The computer 10 applies a predetermined carbon dioxide emission calculation model based on all transportation data to calculate the carbon dioxide emission amount for all transportations for the shipper during a predetermined period (step S21). The carbon dioxide emission calculation model is the same as the carbon dioxide emission calculation model in step S11 described above. The computer 10 sets a carbon dioxide emission calculation model on the setting screen 30 and calculates the carbon dioxide emission amount by applying the set carbon dioxide emission calculation model. A specific example of how the computer 10 calculates the carbon dioxide emission amount will be described. The computer 10 calculates the carbon dioxide emission amount for each transportation during a predetermined period. The carbon dioxide emission amount for each transportation calculated by the computer 10 is the same as the method for calculating the carbon dioxide emission amount in step S11 described above. The computer 10 calculates the sum of the carbon dioxide emissions for each calculated transportation, and applies the predetermined carbon dioxide emission calculation model based on all transportation data to calculate the carbon dioxide emission amount for all transportations for the shipper during the predetermined period. At this time, the computer 10 calculates the total transportation weight for all transportations during the predetermined period based on the transportation weight for each transportation during the predetermined period, and calculates the total transportation distance for all transportations during the predetermined period based on the transportation distance for each transportation during the predetermined period.

[0048] The computer 10 outputs the carbon dioxide emission amount for a predetermined period for each shipper (step S22). The computer 10 transmits the calculated carbon dioxide emission amount for the predetermined period for each shipper to the information terminal 3. The information terminal 3 displays this carbon dioxide emission amount on its own display unit via a predetermined UI (User Interface) (see FIG. 12). The computer 10 outputs the carbon dioxide emission amount by displaying it on the information terminal 3. The UI output by the computer 10 will be described with reference to FIG. 12. FIG. 12 is a diagram schematically showing an example of a UI output by the computer 10. A UI 40 is shown in FIG. 12. The UI 40 displays a group of icons 41 through which the administrator performs input operations (fiscal year icon 41a, import / export icon 41b, transport mode icon 41c, route icon 41d, cargo type icon 41e, ship type icon 41f, an emissions column 42 for outputting carbon dioxide emissions, a transport weight column 43 for outputting transport weight, and a transport distance column 44 for outputting transport distance). The icon group 41 receives input of the administrator's desired information (fiscal year, import / export, transport mode, route, cargo type, ship type, etc.), and for example, the administrator inputs the desired fiscal year into the fiscal year icon 41a. In FIG. 12, the hatching indicates that an input operation has been performed on the fiscal year icon 41a for fiscal year 2022. When this fiscal year icon 41a is input, the computer 10 executes the processing from step S20 described above and outputs the carbon dioxide emissions for each shipper for the specified period (fiscal year) to the emissions column 42. In addition, the computer 10 outputs the total transported weight (t) for each shipper for the specified period (fiscal year) to the transported weight column 43, and outputs the total transported distance (km) for each shipper for the specified period (fiscal year) to the transported distance column 44.

[0049] An overview of a second modified example of the processing steps when the carbon dioxide emission calculation system 1 calculates the amount of carbon dioxide emission emitted during transportation in physical distribution in steps S1 to S3 will be described with reference to Fig. 13. Fig. 13 is a diagram showing a flowchart of a second modified example of the carbon dioxide emission calculation process executed by the computer 10. In the second modified example, the computer 10 calculates the amount of carbon dioxide emission for all transportation in a predetermined period (such as each fiscal year) according to the transportation route. Note that detailed explanations of processes similar to those described above will be omitted.

[0050] The computer 10 acquires transportation data relating to all departure dates, arrival dates, loading locations, unloading locations, sea routes, cargo types, and ship types for a specified period of time for transportation by a specified shipper (step S30). The processing in step S30 is the same as the processing in step S20 described above.

[0051] The computer 10 selects a transportation route (step S31). The computer 10 selects a transportation route for calculating carbon dioxide emissions based on the transportation route input by the administrator of the carbon dioxide emission calculation system 1. The computer 10 may select any one transportation route or may select multiple transportation routes.

[0052] The computer 10 applies a predetermined carbon dioxide emission calculation model based on all transportation data for each selected sea route to calculate the carbon dioxide emission amount for all transportation for the shipper in a predetermined period (step S32). The carbon dioxide emission calculation model is the same as the carbon dioxide emission calculation model in step S11 described above. The computer 10 sets a carbon dioxide emission calculation model on the setting screen 30 and calculates the carbon dioxide emission amount by applying the set carbon dioxide emission calculation model. A specific example of how the computer 10 calculates the carbon dioxide emission amount will be described. The computer 10 calculates the carbon dioxide emission amount for each transportation for the selected sea route in a predetermined period. The carbon dioxide emission amount for each transportation for each sea route calculated by the computer 10 is the same as the method for calculating the carbon dioxide emission amount in step S11 described above. The computer 10 calculates the sum of the carbon dioxide emission amount for each transportation for each calculated sea route, and applies the predetermined carbon dioxide emission calculation model based on all transportation data to calculate the carbon dioxide emission amount for all transportation for the shipper in a predetermined period for each selected sea route. At this time, the computer 10 calculates the total transport weight of all transports for each route during a specified period based on the transport weight of each transport during each specified period, and calculates the total transport distance of all transports for each route during a specified period based on the transport distance of each transport during each specified period.

[0053] The computer 10 outputs the carbon dioxide emission amount for a predetermined period for each shipper's sea route (step S33). The computer 10 transmits the calculated carbon dioxide emission amount for each shipper's sea route for the predetermined period to the information terminal 3. The information terminal 3 displays the carbon dioxide emission amount on its display unit via a predetermined UI (see FIG. 14). The computer 10 outputs the carbon dioxide emission amount by displaying the carbon dioxide emission amount on the information terminal 3. Referring to FIG. 14, the UI output by the computer 10 will be described. FIG. 14 is a diagram schematically illustrating an example of the UI output by the computer 10. FIG. 14 shows a UI 50. The UI 50 shows a group of icons 51 (fiscal year icon 51a, import / export icon 51b, transport mode icon 51c, sea route icon 51d, cargo type icon 51e, and ship type icon 51f) through which the administrator performs input operations, an emission amount column 52 for outputting the carbon dioxide emission amount, a transport weight column 53 for outputting the transport weight, and a transport distance column 54 for outputting the transport distance. The icon group 51 accepts input of the administrator's desired information (e.g., fiscal year, import / export, transportation mode, sea route, cargo type, ship type, etc.). For example, the administrator inputs the fiscal year and sea route desired by the administrator into the fiscal year icon 51a and the sea route icon 51d. In FIG. 14, hatching indicates that input operations have been performed on the fiscal year icon 51a for 2022 and the North American route icon 51d. When the fiscal year icon 51a and the sea route icon 51d are input, the computer 10 executes the processing from step S30 described above and outputs the carbon dioxide emissions for the specified period (fiscal year) for each shipper's sea route to the emissions column 52. Additionally, the computer 10 outputs the sum of the transport weight (t) for the specified period (fiscal year) for each shipper's sea route to the transport weight column 53, and the sum of the transport distance (km) for the specified period (fiscal year) for each shipper's sea route to the transport distance column 54.

[0054] The computer 10 may also calculate and output the carbon dioxide emissions for a predetermined period for each piece of transport data of the shipper based on transport data other than the sea route (departure date, arrival date, loading location, unloading location, cargo type, ship type, etc.). Even in this case, as in the second modified example described above, it is sufficient to select transport data, calculate the carbon dioxide emissions for all transports for the shipper for a predetermined period based on all the transport data for each piece of selected transport data, and output the carbon dioxide emissions for the predetermined period for each piece of transport data of the shipper. Furthermore, the computer 10 may not only calculate the carbon dioxide emissions based on each piece of transport data, but also calculate the carbon dioxide emissions based on multiple pieces of transport data.

[0055] The above is an overview of the carbon dioxide emission calculation system 1. According to this carbon dioxide emission calculation system 1, it is possible to more precisely calculate the amount of carbon dioxide emission associated with transportation based on the sea route, cargo type, etc.
