[Technical field]

[0001] The present invention relates to an information processing device, a greenhouse gas reduction amount confirmation method, and a program. [Background technology]

[0002] In recent years, the amount of ESG (Environmental Social Governance) investment has been increasing, and in order to attract ESG investment, environmental measures are required to improve the ratings given by the international non-governmental organization CDP (Carbon Disclosure Project). In such environmental measures, greenhouse gas emissions are calculated based on various data. For example, Patent Document 1 is available as an example of calculation of greenhouse gas emissions.

[0003] [Patent Document 1] JP 2024-017423 A Summary of the Invention [Problem to be solved by the invention]

[0004] However, there are cases of greenwashing, which aims to create the impression of environmental consideration even when there is no greenhouse effect reduction effect and no actual reality. Environmental measures that improve CDP ratings must have effects that can be listed on CDP and be highly reliable to show that they are not greenwashing. However, greenhouse effect reduction effects are calculated based on data that affects greenhouse gases, and it is difficult to verify whether the original data is correct. In addition, for profit-making companies, the costs required to introduce environmental measures are also one of the obstacles to their implementation.

[0005] The present invention has been made in consideration of the above-mentioned circumstances, and aims to provide an information processing device, a method for confirming greenhouse gas reduction amount, and a program that can indicate the degree of contribution to the environment based on highly reliable data while keeping implementation costs down. [Means for solving the problem]

[0006] In order to achieve the above-mentioned objective, one aspect of the present invention is an information processing device comprising: a cultivation information acquisition unit that acquires environmental data related to greenhouse gases from a sensor device placed in a plant cultivation area; an environmental contribution calculation unit that calculates the greenhouse gas reduction effect due to carbon absorption associated with the cultivation of the plant as a contribution based on the environmental data; and an environmental contribution presentation unit that performs processing to present the contribution. Effect of the Invention

[0007] According to the present invention, it is possible to provide an information processing device, a greenhouse gas reduction amount confirmation method, and a program that can indicate the degree of contribution to the environment based on highly reliable data while suppressing implementation costs.

[0009] <System configuration> An embodiment of the present invention will now be described with reference to the accompanying drawings. First, the overall system configuration will be described. FIG. 1 is a diagram showing an environmental contribution presentation system 100 in which an information processing device 1 according to an embodiment of the present invention is used.

[0010] The environmental contribution presentation system 100 is realized by an information processing device 1 that transmits and receives various information to and from a producer terminal 2 and a company terminal 3 via a communication network such as the Internet. The information processing device 1 is a computer that provides various information related to greenhouse gas calculation to the producer terminal 2 and the company terminal 3, and functions as a server.

[0011] The producer terminal 2 is a computer used by a producer who cultivates tea. The producer produces tea by, for example, organic cultivation in accordance with JAS (Japanese Agricultural Standards).

[0012] The producer terminal 2 is configured by a tablet, a smartphone, a personal computer, etc. The producer terminal 2 may exchange various information with the information processing device 1 by a pre-installed program (application), or may exchange various information through a web browser.

[0013] The company terminal 3 is a computer used by a company employee who consumes the plants produced by the producer. In this embodiment, the plants are tea and consumed as beverage 101. The company terminal 3 is configured with a personal computer, a tablet, a smartphone, or the like. The company terminal 3 may exchange various information with the information processing device 1 by a pre-installed program (application), or may exchange various information through a web browser.

[0014] <Service details> 2 is a schematic diagram showing the contents of the services provided by the environmental contribution presentation system 100. The environmental contribution presentation system 100 provides a service to a company to change the consumption activity of a beverage 101 into a carbon reduction activity.

[0015] Tea plantations absorb carbon as forests. The information processing device 1 acquires information about greenhouse gases (GHG) from sensor devices 50 arranged in the tea plantations, and calculates the effect of reducing greenhouse gases (GHG) by purchasing beverages 101 produced in the tea plantations. From the viewpoint of reducing plastic, it is preferable that the beverages 101 are containers made of sustainable materials such as paper cartons rather than PET bottles.

[0016] Tea producers can create environmental value for the tea they sell by calculating the greenhouse gas reduction effect using the information processing device 1. Tea plantations can be preserved when companies consume beverages 101 that have been given environmental value. Stable sales will enable contract cultivation and the expansion of managed farmland, and the survival of tea plantations will contribute to society by addressing the problem of abandoned farmland and carbon absorption. In addition, by using organic cultivation, which reduces the amount of nitrogen fertilizer used by 40% compared to conventional farming methods, the carbon generated by cultivation can be further reduced.

[0017] On the other hand, companies can obtain environmental benefits that can be recorded in the CDP by replacing the beverages they currently use with beverages 101 produced by tea producers. In addition, companies can obtain environmental values ​​such as data on carbon reductions associated with beverage consumption activities from the information processing device 1 through a dashboard or the like displayed on the company terminal 3.

[0018] In addition, the container of the beverage 101 can be provided with an identification code 102 such as a QR code (registered trademark) for displaying information indicating the contribution to the environment and an LP (Landing Page) page on a terminal with a camera function such as a smartphone. The LP page displayed on the terminal displays various information such as the tea plantation in which the beverage 101 is produced, the tea plantation situation explaining what kind of tea plantation it is, the environmental value of using the beverage 101, the producer's efforts to create the environmental value, introductions of companies that support the efforts, product details of the beverage 101 as a product, and the features of the product. This allows the company's social and environmental efforts to be easily promoted by having the QR code (registered trademark) of the beverage 101 read at a meeting or the like, and the contribution activities can be disseminated externally. This can also lead to reduced costs due to the acquisition of a good reputation among customers and investors, and increased loyalty within the company.

[0019] <Sensor device> 3 and 4, a sensor device 50 that acquires environmental data from a cultivation area will be described. The sensor device 50 is an IOT (Internet of Things) device that acquires soil data of the soil where tea is cultivated, and information on greenhouse gases such as carbon dioxide, such as carbon dioxide concentration, air temperature, and amount of sunlight. The soil data includes, for example, soil temperature, soil EC (electrical conductivity), soil pH, soil moisture content, and the contents of the three major nutrients (nitrogen, phosphorus, and potassium).

[0020] Fig. 3 is a schematic diagram showing the configuration of a sensor device 50. The sensor device 50 shown in Fig. 3 includes a case 51, a microcomputer module 52, a camera 53, an environment sensor module 54, a soil sensor module 55, a solar panel module 56, and a communication module 57.

[0021] The case 51 has a transparent transmission section 58. Inside the transmission section 58, a microcomputer module 52, a camera 53, an environmental sensor module 54, a communication module 57, and the like are arranged.

[0022] The microcomputer module 52 is an electronic component that controls the camera 53, the environmental sensor module 54, the communication module 57, etc. The camera 53 is an imaging device that acquires image data or video data of the location where the sensor device 50 is installed. The environmental sensor module 54 is also a temperature sensor, a humidity sensor, and an air pressure sensor that measure environmental data such as temperature, humidity, and air pressure of the location where the sensor device 50 is installed. The environmental sensor module 54 may also have a function as a carbon dioxide concentration sensor that directly detects the carbon dioxide concentration.

[0023] The soil sensor module 55 is disposed outside the case 51 and acquires soil data. The solar panel module 56 is disposed outside the case 51 and supplies power to power the sensor device 50 by solar power generation. It is also possible to calculate the amount of sunlight from the amount of power generated by the solar panel module 56. The communication module 57 is a communication device such as a 3G line that transmits the environmental data acquired by the sensor device 50 to the outside.

[0024] Fig. 4 is a schematic diagram showing an example of the arrangement of the sensor devices 50. A plurality of sensor devices 50 are arranged in a tea field where tea is cultivated. In Fig. 4(a), a total of 16 sensor devices 50 are arranged at intervals of 25 m per hectare, and each sensor device 50 has an area of ​​625 mm. 2 In FIG. 4(b), a total of nine sensor devices 50 are placed at intervals of 33 m over an area of ​​1 ha, and each sensor device 50 has a resolution of 1089 mm. 2 In FIG. 4(c), a total of four sensor devices 50 are placed at intervals of 50 m over an area of ​​1 ha, and each sensor device 50 has a distance of 2500 mm. 2 The sensor device 50 acquires environmental data in a range of 100 to 200 mm. The arrangement example in FIG. 4 is merely an example, and the number of sensors and the intervals between sensors can be changed as appropriate. Although the sensor device 50 is not particularly limited, it is preferable that the sensor device 50 can sense at least one of the pH (hydrogen ion exponent), EC (electrical conduction), and nitrogen content of the soil. A plurality of sensor devices 50 may be provided.

[0025] <Hardware configuration> 5 is a block diagram showing a hardware configuration of the information processing device 1 according to this embodiment. The information processing device 1 includes a CPU (Central Processing Unit) 11 as a processor, a ROM (Read Only Memory) 12, a RAM (Random Access Memory) 13, a bus 14, an input / output interface 15, an output unit 16, an input unit 17, a storage unit 18, a communication unit 19, and a drive 20.

[0026] The CPU 11 executes various processes according to a program recorded in the ROM 12 or a program loaded from the storage unit 18 to the RAM 13. The RAM 13 also stores data and the like required for the CPU 11 to execute various processes. The CPU 11, the ROM 12, and the RAM 13 are interconnected via a bus 14. An input / output interface 15 is also connected to this bus 14.

[0027] An output unit 16, an input unit 17, a storage unit 18, a communication unit 19, and a drive 20 are connected to the input / output interface 15. The output unit 16 is composed of a display, a speaker, etc., and outputs various information as images and sounds. The input unit 17 is composed of a keyboard, a mouse, etc., and inputs various information. The storage unit 18 is composed of a hard disk, a DRAM (Dynamic Random Access Memory), a SSD (Solid State Drive), etc., and stores various data. The communication unit 19 communicates with other devices via a network including the Internet.

[0028] Removable media 21, which may be a magnetic disk, an optical disk, a magneto-optical disk, or a semiconductor memory, is appropriately attached to the drive 20. Programs read from the removable media 21 by the drive 20 are installed in the storage unit 18 as necessary. The removable media 21 can also store various data stored in the storage unit 18 in the same manner as the storage unit 18.

[0029] The hardware configuration described here is merely an example. The computer described in this embodiment including the information processing device 1 may have a configuration common to that of FIG. 5, or may have a different configuration. The computer may also be composed of two or more computers. The producer terminal 2 and the company terminal 3 in FIG. 1 are, for example, a smartphone, tablet, or personal computer having the same hardware configuration as that shown in FIG. 5.

[0030] <Functional configuration> Fig. 6 is a functional block diagram showing an example of the functional configuration of the information processing device 1 according to this embodiment. The information processing device 1 transmits and receives various data to and from the outside via an API (Application Programming Interface), processes data input from producers, and links data between producers and customer companies. Next, each function of the information processing device 1 that realizes the environmental contribution presentation system 100 will be described with reference to Fig. 6.

[0031] As shown in FIG. 6, the information processing device 1 includes a producer management unit 31, a cultivation information acquisition unit 32, an environmental contribution calculation unit 33, a fertilization method proposal unit 34, a producer support unit 35, a certification acquisition support unit 36, a document creation support unit 37, a new farmer support unit 38, a customer company management unit 41, an environmental contribution presentation unit 42, and a data certification management unit 43 as functional units realized on a processor (CPU 11).

[0032] The producer management unit 31 performs login and logout processing for producers, as well as registration and modification processing of producer registration information. The producer registration information is input by the producer via the producer terminal 2, for example.

[0033] The cultivation information acquisition unit 32 registers and modifies environmental data related to greenhouse gases. The environmental data includes cultivation information carried out by the producer, fertilizer information used by the producer in the tea field, and biodiversity information indicating biodiversity. The cultivation information includes, for example, the type of plant in question, the location of the tea plantation, the area of ​​the cultivated land where the plant is cultivated, the amount of sunlight, soil data, and the like. The fertilization information includes, for example, the type of fertilizer, the amount of fertilizer, and the timing of fertilization. The diversity information is, for example, an image containing organisms as subjects for confirming biodiversity, information on the habitat of organisms that indirectly indicates the presence of organisms, and the like. The environmental data may be information input by the producer through the producer terminal 2, or may be information acquired from the sensor device 50 via a communication network.

[0034] <Registering environmental data> The process of registering environmental data by a producer will be described with reference to Fig. 7 and Fig. 8, taking fertilization information as an example. Fig. 7 is a diagram showing an example of a registration screen for fertilization information. Fig. 7 shows a screen displayed on the producer terminal 2 for the producer to register fertilization information. By operating the producer terminal 2 on this screen, the producer can set the date of fertilization using the calendar function, register fertilization information using a file, and write down any special notes. The fertilization information includes the date of fertilization, the type of fertilizer, information identifying the tea plantation to which fertilization was performed (Tea Plantation A, Tea Plantation B, Tea Plantation C, etc.), the amount of fertilizer, etc.

[0035] The fertilization information may be registered by the cultivation information acquisition unit 32 through input by the producer on the producer terminal 2, or may be acquired by the cultivation information acquisition unit 32 along with the registration of a file. Furthermore, the fertilization information may be acquired from a sensor device 50 arranged in the tea field.

[0036] Fig. 8 is a diagram showing an example of a confirmation screen for the fertilization history. Fig. 8 shows a screen displayed on the producer terminal 2 for confirming the past fertilization history performed by the producer. The registered fertilization information can be confirmed by the fertilization history. The fertilization history displays the date on which the fertilization was performed, the type of fertilizer, information identifying the tea plantation to which the fertilization was performed (Tea Plantation A, Tea Plantation B, Tea Plantation C, etc.), the amount of fertilizer, etc.

[0037] Next, the environmental contribution calculation unit 33 will be described. The environmental contribution calculation unit 33 calculates the greenhouse gas reduction effect due to carbon absorption accompanying the cultivation of plants as the environmental contribution based on the environmental data acquired by the cultivation information acquisition unit 32. The greenhouse gas reduction effect is, for example, the GHG absorption amount, the environmental load reduction degree, the amount of abandoned farmland reduction, etc. The greenhouse gas reduction amount is calculated based on the carbon absorption amount.

[0038] <Calculation method for carbon absorption> Fig. 9 is a schematic diagram for explaining a method for calculating the amount of carbon absorption in a tea field. As shown in Fig. 9, the environmental contribution calculation unit 33 calculates the amount of carbon absorption in a tea field based on the cultivation information, and calculates the amount of carbon emitted by fertilizer based on the fertilization information. The amount of carbon absorption in a tea field can be calculated taking into consideration the type of plants growing in the tea field, the area of ​​the tea field, the amount of sunlight, temperature, humidity, etc. The method for calculating the amount of carbon absorption in a tea field is not particularly limited, and a known calculation method can be used.

[0039] The environmental contribution calculation unit 33 calculates a highly reliable carbon absorption amount by tea cultivation by subtracting the amount of carbon emissions used in cultivating the tea plantation from the carbon absorption amount of the tea plantation. Furthermore, the environmental contribution calculation unit 33 can calculate the greenhouse effect reduction amount of a customer who purchases the beverage 101 based on the carbon absorption amount of the tea plantation and the purchase amount of the beverage 101. The greenhouse effect reduction amount (e.g., CO2 reduction amount) can be calculated using various existing methods.

[0040] The environmental load reduction degree is an index showing the degree of biodiversity conservation. The environmental load reduction degree is calculated from information on living organisms included as subjects in image data acquired from the sensor device 50. The environmental contribution calculation unit 33, for example, analyzes the image data, continuously monitors the types and numbers of insects, animals, etc. included in the image, and makes a judgment based on the transition of the types and numbers. Alternatively, the environmental contribution calculation unit 33 may calculate the environmental load reduction degree based on the growth environment that maintains biodiversity based on the area of ​​the tea field, the types of cultivated plants, etc. acquired from the cultivation information. For example, biodiversity can be evaluated from the following perspectives: Changes in land use (land that has been used for farming for many years is highly rated, clearing forests for farming is rated low) The environmental impact of land use (compared to conventional farming methods that use pesticides and chemical fertilizers, which have a large environmental impact)

[0041] The amount of abandoned farmland reduction is calculated based on, for example, the area of ​​tea fields registered in the cultivation information. When existing abandoned farmland is used to create farmland, or when land that producers were planning to abandon is used, the amount of abandoned farmland reduction is increased.

[0042] The fertilization method suggestion unit 34 suggests a fertilization method to the producer based on the cultivation information. The fertilization method suggestion unit 34 of this embodiment proposes a fertilization method that enhances the greenhouse gas reduction effect. Specifically, the fertilization method suggestion unit 34 presents the type of fertilizer, the amount of fertilizer, the timing of fertilization, etc., based on the sensing results (pH, EC, nitrogen amount, etc.) of the sensor device 50 as a fertilization method suggestion. An example of a fertilization method will be described.

[0043] Crops in tea fields are one of the crops that generate a large amount of GHG (Green House Gas). In Japanese tea, the "umami" is emphasized, and the application of a large amount of nitrogen fertilizer is essential to bring out that flavor. However, currently, excessive nitrogen fertilizer is applied, which results in negative aspects such as soil deterioration, pressure on farmers' management, and GHG emissions from nitrogen fertilizer. On the other hand, it is not necessarily true that excessive fertilization improves the growth of tea, and it is known that even if nitrogen is applied, more than a certain amount is not absorbed by the tea. In other words, most of the nitrogen fertilizer applied in excess is wasted. One of the causes of this is the problem that the appropriate timing and amount of fertilization are unknown. Therefore, in this embodiment, this problem is improved and tea with low environmental impact can be produced.

[0044] As an example of pH, it is known that soil pH of 3.5 or lower damages roots and reduces nitrogen absorption. It is also known that nitrogen is more likely to be released as nitrous oxide at a pH of 4.0 or lower. For this reason, the fertilization method suggestion unit 34 suggests that it is time to apply fertilizer when the soil pH is higher than a predetermined value (Th1; for example, 4). This will contribute to improving the absorption rate of nitrogen fertilizer in tea fields.

[0045] As an example of EC, when the soil EC is high, a lot of nitrogen remains in the soil, reducing the efficiency of fertilizer, so the fertilization method suggestion unit 34 suggests that it is time to fertilize when the soil EC is lower than a predetermined value. This will contribute to improving the absorption rate of nitrogen fertilizer in tea fields.

[0046] As an example of the amount of nitrogen, it is known that the amount of nitrogen absorbed by tea is constant even if a large amount of nitrogen fertilizer is added. Therefore, the fertilization method suggestion unit 34 senses the amount of nitrogen per unit area and suggests the amount of nitrogen fertilizer so that the amount of nitrogen does not exceed the above-mentioned fixed amount (predetermined amount) for the sensed amount of nitrogen. This will enable farmers to reduce the amount of fertilizer they use and is expected to lead to more environmentally friendly tea plantation management.

[0047] As described above, by applying fertilizer efficiently, the amount of nitrogen fertilizer that can be reduced compared to the case of excessive fertilization up until now can be known, and the cost reduction and the amount of GHG derived from the nitrogen fertilizer can be visualized. Conventionally, various soil sensors have been used, all of which are sensors for monitoring the growth of crops, but in this embodiment, the environmental load in agriculture can be visualized.

[0048] In addition, the fertilization method proposing unit 34 may acquire soil data from the sensor device 50 and adjust the timing of fertilization and the amount of fertilizer depending on the soil's ability to absorb the fertilizer.

[0049] The producer support unit 35 displays various support information for supporting producers on the producer terminal 2. The support information includes cultivation information, fertilizer information used by the producer in the tea field, customer information, product information, etc. Product information is information that indicates what kind of customers and companies are using the produced tea leaves.

[0050] <Cultivation and fertilization information> FIG. 10 is a diagram showing an example of the cultivation information and fertilization information displayed on the producer terminal 2. In the example screen of FIG. 10, a bar graph of monthly production volume compared to the previous year is displayed based on the cultivation information input by the producer. A line graph of monthly fertilization input is displayed based on the fertilization information input by the producer, and line graphs of the soil Ph value for the most recent week and the soil EC value for the year, and a bar graph of the soil moisture content by month are displayed based on the cultivation information acquired from the sensor device 50. A production area map is displayed based on the address based on the cultivation information, and a production area image is displayed based on the image information acquired from the sensor device 50. The production area image may be an image captured by a camera other than the sensor device 50.

[0051] Producers can check various types of information such as cultivation information as shown in Figure 10, and can accurately grasp the state of the tea field while managing cultivation such as fertilization. In addition, at the top of the screen shown in Figure 10, a notification section is displayed stating, "JAS certification is ready. Please apply for the procedure from Organic JAS application." By checking the contents of the notification section, producers can ensure that they do not forget to do any tasks that they need to do.

[0052] Next, the certification acquisition support unit 36 ​​will be described. The certification acquisition support unit 36 ​​supports the producer in obtaining certification from a certification body. For example, the certification acquisition support unit 36 ​​displays a support screen for supporting certification by pressing an application button (not shown) on the screen of the producer terminal 2.

[0053] <Support Information> Fig. 11 and Fig. 12 are diagrams showing an example of support information. Fig. 11 is a diagram showing the first half of the support information for supporting certification acquisition displayed on the producer terminal 2, and Fig. 12 is a diagram showing the second half of the support information. When the certification acquisition support unit 36 ​​receives an instruction from the producer to display the support information, it performs processing to display the support information as shown in Fig. 11 and Fig. 12 on the producer terminal 2.

[0054] In Fig. 11 and Fig. 12, the steps for obtaining certification are shown in a chronological flow. In this example, support information for assisting in obtaining JAS organic certification is shown. In Fig. 11, steps such as "Understand JAS certification", "Learn about JAS certification bodies", "Prepare for JAS certification", "Submit an application", "Inspection and evaluation", and "Obtain certification" are shown in chronological order. In addition, each step is displayed with text showing advice for performing the step and a check button showing whether or not the step has been performed. Note that in this example, JAS organic certification is shown as the certification to be obtained, but the certification body is not limited to JAS organic certification.

[0055] The certification acquisition support unit 36 ​​makes it possible to grasp the work required for certification, effectively reducing the burden on producers for certification acquisition. It is difficult to expand tea cultivation in mountainous areas compared to tea cultivation in flat areas, so many producers acquire organic JAS certification to differentiate themselves from others. The support function of the certification acquisition support unit 36 ​​is particularly effective for such producers.

[0056] The document creation support unit 37 creates documents in a prescribed format based on data registered by the producer, such as cultivation information. For example, documents in a prescribed format are documents to be submitted to agricultural cooperatives or agricultural committees. The document creation support unit 37 creates documents to be submitted in a prescribed format by applying information entered by the producer to a preset template. The support function of the document creation support unit 37 can reduce the time and effort required for creating complicated documents, effectively reducing the burden on the producer.

[0057] The new farmer support unit 38 is a support function for new farmers. When the support function for new farmers is selected on the producer terminal 2, the new farmer support unit 38 displays information for new farmers on the producer terminal 2.

[0058] The customer company management unit 41 performs login and logout processing for customer companies, and also performs registration and change processing for customer company registration information. The customer company registration information is input by the producer via the producer terminal 2, for example.

[0059] The environmental contribution presentation unit 42 presents to the company terminal 3 contribution information indicating the contribution to the environment associated with the consumption of the beverage 101. The contribution information is generated based on various information such as the GHG absorption amount, the environmental load reduction amount, and the amount of abandoned farmland reduction calculated by the environmental contribution calculation unit 33. The environmental contribution presentation unit 42 calculates, for example, the GHG absorption amount, the environmental load reduction amount, the amount of abandoned farmland reduction, etc. according to the purchase amount of the beverage 101 by the customer company, and presents them to the company terminal 3.

[0060] <Contribution information> Fig. 13 is a diagram showing an example of the contribution degree information displayed on the enterprise terminal 3. When the environmental contribution degree presentation unit 42 receives an instruction from the enterprise person in charge to display the contribution degree information, it performs a process for displaying the contribution degree information as shown in Fig. 13 on the enterprise terminal 3.

[0061] The upper part of the screen in FIG. 13 displays information on GHG absorption, information on the degree of environmental load reduction, and information based on the amount of abandoned farmland reduction. The information on GHG absorption includes the annual reduction amount (57 t in the example of FIG. 13) and a graph showing the trend of GHG absorption over the past week. The information on the degree of environmental load reduction includes the annual biodiversity retention rate (30% in the example of FIG. 13) and a graph showing the trend of biodiversity retention over the year. The information based on the amount of abandoned farmland reduction includes the annual amount of abandoned farmland reduction (0.9 ha in the example of FIG. 13) and a bar graph showing the trend of the amount of abandoned farmland reduction by month.

[0062] 13, information on the consumption of beverage 101 by year and information on the change in consumption of beverage 101 compared to the previous year are displayed at the bottom. In this example, the information on the consumption of beverage 101 by year is a graph showing the change in tea consumption by year, and the information on the change in consumption of beverage 101 compared to the previous year is a bar graph showing the change in tea consumption by month compared to the previous year.

[0063] The environmental contribution presentation unit 42 also performs processing for displaying a production area map and a production area image as shown in Fig. 10 on the company terminal 3. For example, by scrolling or tapping the screen in Fig. 13 downward, a production area map and a production area image as shown in the lower part of Fig. 10 are displayed. Furthermore, the environmental contribution presentation unit 42 can also display traceability information such as the production area and producer of the beverage 101, which is a product used by the customer company, on the company terminal 3.

[0064] Furthermore, the environmental contribution presentation unit 42 displays a notification section at the top of the screen in Fig. 13. The notification section displays a message saying "A certificate of GHG reduction has been issued. Please download it from the certificate menu." The company's personnel can display and save the certificate on the company's terminal 3 by performing an operation to download the certificate issued by the data certification management unit 43.

[0065] Next, the data certification management unit 43 will be described. The data certification management unit 43 performs processing to ensure the reliability of various information presented by the environmental contribution presentation unit 42. The data certification management unit 43 of this embodiment performs a cooperative process of describing in the blockchain the calculation results of the environmental contribution calculation unit 33, environmental data (original data) such as cultivation information and fertilization information that form the basis of the calculations of the environmental contribution calculation unit 33, and contribution information according to the purchase amount of the beverage 101. By using the blockchain, it is possible to prevent tampering and prove that the contribution to the environment is not greenwashing or the like.

[0066] The data certification management unit 43 also performs processing for displaying on the company terminal 3 a certificate indicating that the various social impacts indicated by the contribution information and the like have not been tampered with.

[0067] <Processing flow> FIG. 14 is a flowchart showing the flow of the environmental contribution presentation process executed by the information processing device 1.

[0068] In step S10, the cultivation information acquisition unit 32 acquires environmental data such as cultivation information from the sensor device 50, and also acquires environmental data such as fertilization information input on the producer terminal 2.

[0069] In step S11, the environmental contribution calculation unit 33 calculates the greenhouse gas reduction effect due to carbon absorption accompanying the cultivation of the plant as a contribution based on the environmental data acquired by the cultivation information acquisition unit 32.

[0070] In step S12, when the environmental contribution presentation unit 42 receives a view request from the company terminal 3, the process proceeds to step S13. If there is no view request from the company terminal 3, the environmental contribution presentation unit 42 returns the process to step S10.

[0071] In step S13, the environmental contribution presentation unit 42 performs processing for presenting the contribution to the environment based on the greenhouse gas reduction effect calculated by the environmental contribution calculation unit 33 to the company terminal 3 that has made the viewing request. In this embodiment, the GHG absorption amount, the environmental load reduction degree, the amount of abandoned farmland reduction, and the like are displayed on the dashboard screen of the company terminal 3 as shown in Fig. 13. If the consumption amount of the beverage 101 is set by the company terminal 3, the greenhouse gas reduction effect according to the consumption amount of the beverage 101 on the company terminal 3 is displayed. After the processing of step S13, the processing returns to step S10 and the subsequent processing is repeated.

[0072] (1) As described above, the information processing device 1 of this embodiment includes a cultivation information acquisition unit 32 that acquires environmental data related to greenhouse gases from a sensor device 50 placed in a plant cultivation area, an environmental contribution calculation unit 33 that calculates the greenhouse gas reduction effect due to carbon absorption associated with plant cultivation as a contribution based on the environmental data, and an environmental contribution presentation unit 42 that performs processing to present the contribution to the environment based on the greenhouse gas reduction effect. By configuring the information processing device 1, the greenhouse gas reduction confirmation method, and the program in this way, it is possible to prove the greenhouse gas reduction effect by replacing existing products with tea, which is a plant to be cultivated, based on objective data acquired from cultivation sites such as tea farms. Since producers can add contributions to the environment to beverages 101 (products) made from tea (plants), the added value can increase the sales price of the beverages 101 and increase the continuity of the plant cultivation business. Since tea farms are stably maintained, this can also lead to preventing abandoned farmland. Consumers such as client companies that consume plants can also eliminate concerns about greenwashing by using reliable data acquired from cultivation sites. Client companies can easily introduce measures related to environmental sustainability by simply replacing the beverages they have been consuming with the target beverages 101 without making large-scale capital investments. By using a dashboard or the like as in this embodiment, it is also easy to visualize social impacts.

[0073] (2) In addition, in this embodiment, the environmental contribution presentation unit 42 performs processing for presenting the contribution according to the consumption amount of plants based on the greenhouse gas reduction effect. This allows the degree of contribution to the environment to be confirmed according to the consumption amount of the beverage 101, etc. By replacing the beverage 101, the degree of contribution of which can be confirmed, the effect of reducing greenhouse gases can be quantitatively confirmed.

[0074] (3) In addition, in this embodiment, the cultivation information acquisition unit 32 acquires information input by the producer as environmental data. This allows the greenhouse gas reduction effect to be calculated more accurately based on the environmental data input by the producer. In addition, the environmental data input by the producer can be corroborated by the environmental data acquired from the sensor device 50, and the reliability of the contribution degree presented on the company terminal 3 can be improved.

[0075] (4) In addition, in this embodiment, the cultivation information acquisition unit 32 acquires fertilizer information regarding the fertilizer applied to the plant, and the environmental contribution calculation unit 33 calculates the greenhouse gas reduction effect by reflecting the carbon emission amount based on the fertilizer information. This allows for a more reliable calculation of greenhouse gas reductions, as the carbon emissions of fertiliser are taken into account.

[0076] (5) Moreover, the information processing device 1 of this embodiment further includes a fertilization method suggesting unit 34 that suggests to the plant producer a fertilizer application method that will increase the contribution level based on the fertilizer information. This allows fertilizer to be applied in a way that contributes more to the environment, further increasing the added value of the tea (plant).

[0077] (6) Furthermore, in this embodiment, the environmental contribution calculation unit 33 calculates a biodiversity value indicating the degree of biodiversity based on the environmental data, and the environmental contribution presentation unit 42 presents the biodiversity value as one of the degrees of contribution. This will allow the company to demonstrate its contribution to biodiversity, which is a concern due to the effects of climate change, and will further motivate its client companies to purchase plant-based beverages.

[0078] (7) In this embodiment, the cultivation information acquisition unit 32 acquires image data of the cultivated land, and the environmental contribution calculation unit 33 calculates the biodiversity value based on the image data. This makes it possible to calculate a more objective and reliable biodiversity value by using image data capturing images of the cultivated land.

[0079] (8) Furthermore, the method for confirming greenhouse gas reduction amount of this embodiment includes a cultivation information acquisition step of acquiring environmental data related to greenhouse gases from a sensor device 50 placed in a plant cultivation area, an environmental contribution calculation step of calculating the greenhouse gas reduction effect due to carbon absorption associated with the cultivation of the plant based on the environmental data, and an environmental contribution presentation step of performing processing to present the contribution to the environment based on the greenhouse gas reduction effect. (9) The program of the present embodiment also causes a computer to execute steps similar to those included in the method for confirming greenhouse gas reduction amounts.
