Description

Application of Article 30, Paragraph 2 of the Patent Act (1) Disclosure on the website Disclosure date: June 1, 2022 URL: https://www. mitsui-soko. com/sustainalink/emissions_calculator/

The present invention relates to a greenhouse gas emission calculation device, a control method for a greenhouse gas emission calculation device, and a program.

Currently, specific emitters that emit a certain amount of greenhouse gases or more are required to calculate their own greenhouse gas emissions and report them to the government. While the government tallys up and publishes these emissions, each business is working to further reduce its emissions.

In addition, as the importance of addressing these environmental issues becomes more widely recognized in society, an increasing number of businesses and individuals are becoming interested in their own greenhouse gas emissions.

In this context, technology has been developed that can calculate the amount of CO2 emissions generated during cargo transport through simulation (see, for example, Patent Document 1).

JP 2020-003216 A

However, for businesses and individuals who do not have specialized knowledge or prior knowledge about greenhouse gas emissions, it is difficult to set the conditions for calculating greenhouse gas emissions, and even if they obtain detailed calculation results, they find it difficult to understand them.

==Overall Configuration==
FIG. 1 shows an overall configuration diagram of a greenhouse gas emission calculation system 1000 according to one embodiment of the present invention.

The greenhouse gas emission calculation system 1000 is configured by connecting a greenhouse gas emission calculation device 200 and a greenhouse gas emission calculation device 300 so that they can communicate with each other via a network 500. The greenhouse gas emission calculation system 1000 is also connected to a user terminal 100 so that they can communicate with each other via the network 500.

The network 500 is any of various information and communication networks such as the Internet, a LAN (Local Area Network), or a telephone network.

The user terminal 100 is an information processing device such as a personal computer, smartphone, or tablet that is owned by a user such as a business or individual who calculates the amount of greenhouse gas emissions emitted during cargo transportation.

In this embodiment, carbon dioxide (CO2), which has the largest total emissions of all greenhouse gases, is used as the target of calculation, but the target greenhouse gases may include carbon dioxide, carbon monoxide (CO), methane, and fluorocarbons, or a combination of these.

When calculating CO2 emissions, the user causes the user terminal 100 to display an initial screen (input screen) as shown in FIG. 9. Then, the user inputs transport conditions, specifying the cargo transport volume, departure point, destination, and one or more transport methods (airmail, sea mail, truck mail, etc.), as shown in FIG. 10.

When the user clicks or touches "Calculate CO2 emissions with this information" displayed in column (J) of Figure 10, the transportation conditions are sent from the user terminal 100 to the greenhouse gas emission calculation device 200, and the greenhouse gas emission calculation device 200 returns the CO2 calculation results to the user terminal 100.

The greenhouse gas emission calculation device 200 is an information processing device such as a computer that accepts input of the transport conditions for cargo transport transmitted from the user terminal 100 and displays the greenhouse gas emission amount calculated based on the transport conditions on the user terminal 100. At this time, an output screen showing the calculation results, such as that shown in Figures 11 and 12, is displayed on the user terminal 100.

The greenhouse gas emission calculation device 300 is an information processing device such as a computer that receives a calculation instruction for greenhouse gas emissions from the greenhouse gas emission calculation device 200 and transmits the calculation result to the greenhouse gas emission calculation device 200.

In this embodiment, the greenhouse gas emission calculation device 300 is configured by an information processing device different from the greenhouse gas emission calculation device 200, but it may be configured by the same information processing device as the greenhouse gas emission calculation device 200. Similarly, it may be configured by the same information processing device as the greenhouse gas emission calculation device 200.

The information processing device according to this embodiment may also be a virtual machine or a cloud computer.

Details are explained below.

==Greenhouse gas emissions calculation device==
First, the hardware configuration of the greenhouse gas emission calculation device 200 will be described with reference to FIG.

The greenhouse gas emission calculation device 200 according to this embodiment is an information processing device including a CPU (Central Processing Unit) 210, a memory 220, a communication device 230, a storage device 240, an input device 250, an output device 260, and a recording medium reading device 270.

The storage device 240 stores various programs and data, such as the greenhouse gas emission calculation device control program 720 executed by the CPU 210.

The greenhouse gas emission calculation device control program 720 and various data stored in the storage device 240 are read into the memory 220 and executed or processed by the CPU 210, thereby realizing various functions of the greenhouse gas emission calculation device 200.

Here, the storage device 240 is a non-volatile storage device such as a hard disk, SSD (Solid State Drive), or flash memory.

As shown in FIG. 5, the storage device 240 stores a greenhouse gas emission calculation device control program 720, transportation conditions 600, and greenhouse gas emission calculation results 610.

The recording medium reader 270 reads the greenhouse gas emission calculation device control program 720 and data recorded on a recording medium 800 such as a CD, DVD, or SD card, and stores them in the storage device 240.

The communication device 230 transmits and receives the greenhouse gas emission calculation device control program 720 and various data to and from the user terminal 100, the greenhouse gas emission calculation device 300, and other computers (not shown) via the network 500. For example, the above-mentioned greenhouse gas emission calculation device control program 720 and data can be stored in another computer, and the greenhouse gas emission calculation device 200 can download the greenhouse gas emission calculation device control program 720 and data from this computer.

The input device 250 is a device such as various buttons, switches, a mouse, and a keyboard that accepts input of commands and data by the operator of the greenhouse gas emission calculation device 200.

The output device 260 is, for example, a display device such as a display, a speaker, etc.

<Transportation conditions>
The transportation conditions 600 stored in the storage device 240 are shown in Fig. 6. The transportation conditions 600 include information on "cargo transportation volume,""unit,""transportationmethod,""startpoint," and "destination." The information included in the transportation conditions 600 is information input by the user from the initial screen displayed on the user terminal 100 as shown in Fig. 10.

The greenhouse gas emission calculation device 200 stores each data of the transportation conditions 600 transmitted from the user terminal 100 in the storage device 240 as shown in FIG. 6.

"Cargo volume" and "unit" indicate the amount of cargo being transported. In addition to "tons," "KG (kilograms)" and "TEU" can be selected as "units." TEU stands for a 20-foot container, and 1 TEU represents one 20-foot container. The weight per 1 TEU is converted to, for example, 24 tons.

"Transportation method" indicates the means of transportation used to transport cargo. In this embodiment, the "Transportation method" can be selected from "Ship", "Airplane", "Truck", "Railroad", and "Coast ship".

"Ships" refers to a method of transporting cargo to a destination in a country different from the point of departure by using a ship to transport the cargo from the port closest to the departure point to the port closest to the destination. Therefore, other means of transport such as trucks or railroads are used for the section from the departure point to the port closest to the departure point, and for the section from the port closest to the destination to the destination. In this embodiment, the means of transport for this section is appropriately selected by the greenhouse gas emission calculation device 200 or the greenhouse gas emission calculation device 300 (for example, a truck is selected), but it may also be possible to allow the user to specify it.

"Airplane" is a method of transporting cargo using an aircraft from the airport closest to the departure point to the airport closest to the destination. Therefore, like "ship," other means of transportation such as trucks and railroads are used for the section from the departure point to the airport closest to the departure point, and for the section from the airport closest to the destination to the destination.

"Truck" is a method of transporting cargo using trucks from the departure point to the destination. Therefore, if there is a section between the departure point and the destination that is not covered by road, such as the sea, ships or planes are used for that section.

"Rail transport" is a method of transporting cargo by rail from the station nearest to the departure point to the station nearest to the destination. Therefore, like "ships" and "planes," trucks are used for the section from the departure point to the station nearest to the departure point, and for the section from the station nearest to the destination to the destination. Also, if there is a section between the departure point and the destination where there is no railroad, such as the sea or mountainous areas, ships, planes or trucks are used for that section.

"Domestic shipping" is a method of transporting cargo to a destination within the same country as the point of departure by using a ship to transport the cargo from the port closest to the departure point to the port closest to the destination. Therefore, just like with "ships," other means of transportation such as trucks and railroads are used for the section from the departure point to the port closest to the departure point, and for the section from the port closest to the destination to the destination.

"Origin" and "destination" represent the starting point and ending point of the cargo transport, respectively. The origin and destination can be specified by city name, airport name, port name, or station name, or by a point on a map (e.g., latitude and longitude).

<Greenhouse gas emissions calculation results>
7 shows the greenhouse gas emission calculation result 610 stored in the storage device 240. The greenhouse gas emission calculation result 610 includes information transmitted to the greenhouse gas emission calculation device 200 by the greenhouse gas emission calculation device 300, which has calculated the greenhouse gas emission amount based on the above-mentioned transportation conditions 600.

The greenhouse gas emission calculation device 200 stores the data including the transport route from the departure point to the destination, the transport distance, and the greenhouse gas emission amount transmitted from the greenhouse gas emission calculation device 300 as the greenhouse gas emission calculation result 610 in the storage device 240.

The greenhouse gas emission calculation results 610 include information on "transportation method," "section," "transportation means," "FROM," "TO," "distance," and "greenhouse gas emission amount," as shown in FIG. 7.

The "Transportation method" field lists the transportation method specified in the transportation conditions 600.

The "Section" field lists the sections of the transportation route that are separated by predetermined stopovers on the transportation route from the departure point to the destination. The transportation route is separated, for example, by points (ports, airports, train stations, etc.) where cargo is transferred to another means of transportation.

The "Means of Transportation" column lists the means of transport for cargo in each section.

The "FROM" and "TO" columns indicate the starting and ending points of each section.

The "Distance" column indicates the transportation distance for each section. In order to calculate greenhouse gas emissions more accurately, it is preferable to enter the transportation distance for each means of transportation (mileage distance for trucks and railroads, and sailing distance for airplanes, ships, and domestic ships), but to simplify calculations, it may also be an approximate distance, such as the straight-line distance from the starting point to the end point of each section.

The "Greenhouse gas emissions" column lists the calculated greenhouse gas emissions when transporting cargo from the starting point to the end point of each section. As described above, in this embodiment, the calculated CO2 emissions are listed.

==User Terminal==
Next, the hardware configuration of the user terminal 100 will be described with reference to FIG.

As shown in FIG. 3, the user terminal 100 is an information processing device that includes a CPU 110, a memory 120, a communication device 130, a storage device 140, an input device 150, an output device 160, and a recording medium reading device 170. The hardware configuration of the user terminal 100 is basically the same as the hardware configuration of the greenhouse gas emission calculation device 200. Therefore, a duplicated explanation of the hardware configuration will be omitted.

As shown in FIG. 3, the storage device 140 stores various programs and data, such as the user terminal control program 710 executed by the user terminal 100.

The user terminal control program 710 and various data stored in the storage device 140 are read into the memory 120 and executed or processed by the CPU 110 to realize various functions of the user terminal 100.

==Greenhouse Gas Emissions Calculation Device==
Next, the hardware configuration of the greenhouse gas emission amount calculation device 300 will be described with reference to FIG.

As shown in FIG. 4, the greenhouse gas emission calculation device 300 is an information processing device including a CPU 310, a memory 320, a communication device 330, a storage device 340, an input device 350, an output device 360, and a recording medium reading device 370. The hardware configuration of the greenhouse gas emission calculation device 300 is basically the same as the hardware configuration of the greenhouse gas emission calculation device 200. Therefore, a duplicated explanation of these hardware configurations will be omitted.

As shown in FIG. 4, the storage device 340 stores various programs and data, such as the greenhouse gas emission calculation device control program 730 executed by the greenhouse gas emission calculation device 300.

The greenhouse gas emission calculation device control program 730 and various data stored in the storage device 340 are read into the memory 320 and executed or processed by the CPU 310, thereby realizing various functions of the greenhouse gas emission calculation device 300.

<Functional configuration of the greenhouse gas emissions calculation device>
Next, the functional configuration of the greenhouse gas emission calculation device 200 will be described with reference to the functional configuration diagram shown in FIG.

As described above, the greenhouse gas emission calculation device 200 realizes various functions as the greenhouse gas emission calculation device 200 by reading the greenhouse gas emission calculation device control program 720 and various data stored in the storage device 240 into the memory 220 and executing or processing them by the CPU 210.

Specifically, the greenhouse gas emission calculation device 200 has the functions of a transport condition reception unit 201, a transport route determination unit 202, a greenhouse gas emission determination unit 203, and an output screen display unit 204.

The transport condition receiving unit 201 receives input of cargo transport conditions 600, which specify the cargo transport volume, departure point, destination, and one or more transport methods. In this embodiment, the greenhouse gas emission calculation device 200 is configured to acquire the transport conditions 600 input by the user to the user terminal 100 from the user terminal 100.

For example, Figures 9 and 10 show the input screen (initial screen) for the transport conditions 600 displayed on the user terminal 100, where columns (A) and (B) are user interfaces that accept the "cargo transport volume." The user can input the cargo transport volume by inputting a number representing the transport volume in column (A) and the unit in column (B). For example, in Figure 10, 100 tons is specified as the cargo transport volume. As mentioned above, in addition to "tons," "KG (kilograms)" and "TEU" can be selected as the "unit."

Column (C) is a user interface that accepts "one or more transportation methods." In this embodiment, the transportation method can be selected from "ship" (first method), "airplane" (second method), "truck" (third method), "railroad" (fourth method), and "coastal ship" (corresponding to the first method in this embodiment). The user can specify one or more transportation methods by selecting the text or icon representing these transportation methods with the mouse or touch operation.

Columns (D), (E), and (H) are user interfaces that accept the "starting point."

For example, in column (D) of FIG. 9, it says "Search from map." In this case, the user can specify the starting point by identifying a point on the map displayed in column (H) with a mouse or touch input. In this case, the starting point is specified by latitude and longitude as shown in FIG. 9.

In addition, in the (D) field, in addition to "Search from map," "Search from city name," "Search from airport name," "Search from port name," and "Search from station name" can be selected by displaying a pull-down menu. In this case, the user can specify the departure point by typing the city name, airport name, port name, or station name in the (E) field. When any alphabet is entered in the (E) field, a list of city names that match the alphabet is displayed in the (E) field. The user can enter the departure point by selecting the corresponding city name, airport name, etc. from this list. This aspect makes it possible to reduce the burden of input work on the user and prevent input errors. Also, when a city name, airport name, port name, or station name is entered in the (E) field, the corresponding point is displayed on the map in the (H) field. This aspect makes it possible for the user to easily check that the departure point has been entered correctly.

Columns (F), (G), and (I) are user interfaces that accept "destinations." The method for inputting a destination is similar to columns (D), (E), and (H), so a detailed explanation is omitted.

In this way, the transportation conditions reception unit 201 according to this embodiment has a user interface for receiving departure points and destinations by inputting or selecting characters representing city names, airport names, port names, or station names, and a user interface for receiving departure points and destinations by inputting a point on a map. This aspect makes it possible to easily input the countless "departure points" and "destinations" that exist around the world, thereby reducing the burden on the user.

This type of approach also makes it easy to set conditions for calculating greenhouse gas emissions during cargo transportation, even if you lack specialized knowledge or prior knowledge about greenhouse gas emissions.

For example, the transport condition receiving unit 201 may receive input of information specifying the type of greenhouse gas (CO2, CO, methane, fluorocarbons, etc.). In this manner, it is possible to calculate the amount of greenhouse gas emissions desired by the user.

Next, the transport route identification unit 202 identifies the transport route from the departure point to the destination for each transport method.

In this embodiment, the transport route specification unit 202 specifies the transport route from the departure point to the destination by sending a specific calculation request to the greenhouse gas emission calculation device 300 together with the transport conditions 600 and acquiring the calculation result of the transport route from the greenhouse gas emission calculation device 300. Of course, the greenhouse gas emission calculation device 200 may specify the transport route by calculating it.

The greenhouse gas emission calculation device 300 has data on the operation of ships (including domestic ships), airplanes, and trains around the world, as well as map data such as road information (or is available from a computer (not shown) communicatively connected via the network 500), and is capable of calculating the transportation route and transportation distance of cargo from the departure point to the destination by specifying the departure point, destination, and transportation method (transportation means).

Specifically, when transporting cargo by ship, the greenhouse gas emission calculation device 300 calculates a transportation route that connects the section from the port closest to the departure point (departure port) to the port closest to the destination (arrival port) via a route with as few transfers as possible, and also calculates the shortest route using trucks or railroads (trucks in this embodiment) for the section from the departure point to the departure port and the section from the arrival port to the destination.

When transporting cargo using a domestic ship, the rules are the same as when transporting by ship, except that the departure and destination are within the same country.

When transporting cargo by airplane, the greenhouse gas emission calculation device 300 calculates a transportation route that connects the section from the airport closest to the departure point (departure airport) to the airport closest to the destination (arrival airport) via an air route with as few transfers as possible, and also connects the sections from the departure point to the departure airport and from the arrival airport to the destination via trucks or railroads (trucks in this embodiment) via the shortest routes.

When transporting cargo by truck, the greenhouse gas emission calculation device 300 calculates the transportation route so as to connect the section from the departure point to the destination via the shortest route. However, if there is a section on the way where there is no road, such as when crossing the sea, the transportation route is calculated so that the section between the nearest port or airport on either side of the sea is transported by ship or plane.

The transport route determination unit 202 calculates the transport route from the departure point to the destination for each section formed by dividing the route by predetermined intermediate points such as cargo transshipment points, and also calculates the transport distance for each section.

The greenhouse gas emission identification unit 203 identifies the greenhouse gas emission amount calculated for each transportation method based on the cargo transportation distance obtained from the transportation route, the cargo transportation volume, and predetermined basic data.

In this embodiment, the greenhouse gas emission determination unit 203 transmits a predetermined calculation request together with the transportation conditions 600 to the greenhouse gas emission calculation device 300, and obtains the calculation result of the emission amount from the greenhouse gas emission calculation device 300, thereby determining the greenhouse gas emission amount. Of course, the greenhouse gas emission calculation device 200 may determine the emission amount by calculating it.

The greenhouse gas emission calculation device 300 has various calculation formulas and basic data for calculating greenhouse gas emissions for each transportation method (transportation means).

For example, the greenhouse gas emission calculation device 300 has various calculation formulas and basic data for calculating CO2 emissions using the conventional ton-kilometer method, the improved ton-kilometer method, the fuel method, and the fuel efficiency method, and can calculate CO2 emissions from this data.

For example, to calculate CO2 emissions using the conventional ton-kilometer method, values for transport distance, transport weight, and CO2 emissions per unit are required, but the greenhouse gas emissions calculation device 300 stores the CO2 emissions per unit for each transport method, and can calculate CO2 emissions using this CO2 emissions per unit, the transport distance calculated from the transport route, and the transport weight.

For example, to calculate CO2 emissions using the fuel method, values for fuel consumption, unit calorific value, and emission coefficient are required, but the greenhouse gas emissions calculation device 300 can calculate CO2 emissions by identifying the type of fuel (diesel for trucks, jet fuel for airplanes, etc.) and the amount of fuel used (calculated from transport distance/fuel consumption) from the transport method and transport distance, and then identifying the unit calorific value and emission coefficient from the type of fuel.

Alternatively, the greenhouse gas emission calculation device 300 may further calculate as greenhouse gas emissions statistical values such as the average or maximum value of values calculated using multiple calculation methods such as the conventional ton-kilometer method, the improved ton-kilometer method, the fuel method, and the fuel efficiency method. This makes it possible to suppress variation and bias in greenhouse gas emissions due to differences in calculation methods.

In addition, since the formulas and basic data for calculating greenhouse gas emissions may be determined by international standards or may differ from country to country, the greenhouse gas emissions calculation device 300 has a variety of these formulas and basic data.

In addition, the greenhouse gas emission calculation device 200 according to this embodiment has the greenhouse gas emission calculation device 300 execute the calculation of the cargo transport route and the greenhouse gas emission amount. With this configuration, it is possible to use an external computer that provides, for example, the calculation of the transport route and the calculation of the greenhouse gas emission amount as a service as the greenhouse gas emission calculation device 300, which reduces the cost and time required to develop and operate the greenhouse gas emission calculation device 300 in-house and enables the provision of a greenhouse gas emission calculation service to users more efficiently.

The output screen display unit 204 displays on the display device an output screen that is generated for each transportation method and has a transportation route image that shows the transportation route on a map and a greenhouse gas emission image that shows the greenhouse gas emission amount in a graph, switching between the output screens in response to an instruction input that selects one of the transportation methods.

In this manner, it is possible to present the calculation results of greenhouse gas emissions during cargo transportation in an easy-to-understand manner, so that even those with little specialized knowledge or prior knowledge regarding greenhouse gas emissions can easily understand them.

For example, the output screen display unit 204 generates an output file (e.g., an HTML file, an XML file, a JSON file, etc.) for displaying an output screen such as that shown in FIG. 11 and FIG. 12 based on the calculation results of the transport route and greenhouse gas emission amount by the transport route identification unit 202 and the greenhouse gas emission amount identification unit 203, and then transmits this output file to the user terminal 100. The user terminal 100 displays this output file on the output device 160 by executing a browser or an app. At this time, the user terminal 100 may obtain map data from an information processing device (not shown) and reflect it on the output screen by using an asynchronous communication technology such as Ajax.

Figure 11 is an output screen that displays the transportation route and greenhouse gas emissions when transporting 100 tons of cargo from Tokyo to Seoul by ship. Figure 12 is an output screen that displays the transportation route and greenhouse gas emissions when transporting 100 tons of cargo from Tokyo to Seoul by airplane.

As shown in Figures 11 and 12, each output screen includes a column (K) displaying a list of the transportation methods specified in the transportation conditions 600, a column (L) displaying a transportation route image in which the transportation route is displayed on a map, a column (M) displaying the calculation results of the greenhouse gas emission amount, and a column (N) displaying a greenhouse gas emission amount image in which the greenhouse gas emission amount is displayed in a graph.

Column (K) displays a list of tabs (or icons) representing the transportation methods that the user can specify (in this embodiment, ship, airplane, truck, railroad, coastal ship). In Figures 11 and 12, among these tabs, the transportation methods (ship, airplane) that the user specified in the transportation conditions 600 are displayed with a solid line, and the transportation methods (truck, railroad, coastal ship) that the user did not specify in the transportation conditions 600 are displayed with a dashed line.

When the user selects a transportation method by clicking the ship or plane tab with the mouse or touching it with a finger or pen, the user terminal 100 displays an output screen corresponding to the selected transportation method. On the other hand, the user terminal 100 does not switch the output screen even if the user attempts to select a tab for a transportation method (truck, rail, coastal ship) that was not specified in the transportation conditions 600.

The (L) column displays a transport route image. This transport route image is generated by combining the transport route identified by the transport route identification unit 202 with a map image. At this time, as described above, map data may be acquired from an information processing device (not shown) by using an asynchronous communication technology such as Ajax, and reflected on the output screen.

In the (M) column, data on "transportation means," "starting point," "destination," "distance," and "CO2 emissions" are displayed for each section from the starting point to the destination. The output screen display unit 204 generates the image to be displayed in the (M) column based on the data stored in the greenhouse gas emissions calculation results 610 shown in FIG. 7.

Column (N) displays an image of the greenhouse gas emissions for each section. This greenhouse gas emissions image is generated by the output screen display unit 204 plotting the greenhouse gas emissions for each section identified by the greenhouse gas emissions identification unit 203 on a two-dimensional graph. In the examples shown in Figures 11 and 12, the greenhouse gas emissions are displayed as a bar graph, but they may also be plotted as other graphs such as a pie chart or a line graph.

By looking at the transport route image displayed in column (L), the user can visually grasp the route the cargo will take to reach its destination, and by looking at the greenhouse gas emissions image displayed in column (N), the user can easily visually understand the difference in emissions for each section of the transport route. Furthermore, by selecting the tab in column (K), this output screen can easily be switched to display each transport method, making it easy to compare each transport method and understand the difference in greenhouse gas emissions due to different transport methods.

In this way, the greenhouse gas emission calculation device 200 according to this embodiment makes it easier to understand greenhouse gas emissions during cargo transportation, which cannot be seen directly and are difficult to grasp. Even if you have little knowledge about greenhouse gases, you can, for example, find sections of the transportation route where greenhouse gas emissions may be reduced, consider other transportation methods, or request a detailed analysis and review from an expert.

==Process flow==
Next, the flow of processing by the greenhouse gas emission calculation system 1000 according to this embodiment will be described with reference to the flowchart shown in FIG.

First, the user terminal 100 transmits a request for an initial screen to the greenhouse gas emission calculation device 200 (S1000). For example, a request specifying the URL (Uniform Resource Locator) of the initial screen is transmitted from a browser running on the user terminal 100.

The greenhouse gas emission calculation device 200 sends an initial screen corresponding to this request to the user terminal 100 (S1010).

The user terminal 100 then displays the initial screen on the output device 160 (S1020). Figure 9 shows the initial screen displayed on the user terminal 100.

On this initial screen, the user inputs the transportation conditions 600 and clicks or touches "Calculate CO2 emissions with these contents," causing the user terminal 100 to transmit the transportation conditions 600 to the greenhouse gas emission calculation device 200 (S1030).

When the greenhouse gas emission calculation device 200 acquires the transportation conditions 600 (S1040), it stores the transportation conditions 600 in the storage device 240 and transmits them to the greenhouse gas emission calculation device 300 (S1050).

The greenhouse gas emission calculation device 300 then calculates the transportation route and transportation distance from the departure point to the destination specified in the transportation conditions 600 for each transportation method, and calculates the CO2 emission amount (S1060).

Then, the greenhouse gas emission calculation device 300 transmits the transportation route, transportation distance, and CO2 emission amount calculated for each transportation method to the greenhouse gas emission calculation device 200 (S1070).

When the greenhouse gas emission calculation device 200 acquires and identifies the transport route, transport distance, and the calculation results of the CO2 emission amount (S1080), it stores them in the storage device 240 as the greenhouse gas emission calculation result 610 and generates an output file (S1090). As described above, this output file is, for example, an HTML file, an XML file, a JSON file, etc., and the greenhouse gas emission calculation device 200 generates the output file so that the output screen, which has a transport route image showing the transport route on a map and a greenhouse gas emission image showing the greenhouse gas emission amount in graph form and is generated for each transport method, is displayed on the display device while switching in response to an instruction input to select one of the transport methods.

The greenhouse gas emission calculation device 200 transmits this output file to the user terminal 100 (S1100).

When the user terminal 100 acquires the output file, the browser displays the output screen on the output device 160 (S1110). The output screen displayed on the user terminal 100 is shown in Figures 11 and 12.

Then, each time the user selects a tab indicating a shipping method by clicking or the like, the user terminal 100 switches and displays the output screen (S1120).

In this manner, it is possible to present the calculation results of greenhouse gas emissions during cargo transport in an easy-to-understand manner.

In this way, the greenhouse gas emission calculation device, the control method and the program for the greenhouse gas emission calculation device according to this embodiment make it possible to present the calculation results of greenhouse gas emissions during cargo transportation in an easy-to-understand manner.

The above-described embodiment is intended to facilitate understanding of the present invention, and is not intended to limit the present invention. The present invention may be modified or improved without departing from its spirit, and equivalents are also included in the present invention.

For example, when inputting the transportation conditions 600 into the user terminal 100, one or more types of greenhouse gases (e.g., at least one of CO2, CO, methane, and fluorocarbons) may be specified. In this case, the greenhouse gas emission calculation system 1000 calculates the amount of emission of each of the specified types of greenhouse gases using a predetermined calculation formula and basic data, and displays each amount in a graph on the user terminal 100. This aspect makes it possible to easily compare the amount of emission of each greenhouse gas emitted when transporting cargo.

For example, when inputting the transportation conditions 600 into the user terminal 100, one or more stopover points may be specified. In this case, the greenhouse gas emission calculation system 1000 calculates a transportation route and greenhouse gas emissions for transporting cargo from the departure point to the destination via the specified stopover points. This aspect makes it possible to specify a cargo transportation route that passes through a company's overseas base, for example, and enables a more appropriate calculation of greenhouse gas emissions that takes into account the individual circumstances of each user.
