Description

[Technical Field]

[0001] The present invention relates to a CO2 reduction management system. [Background technology]

[0002] As is well known, there are calls to reduce CO2 emissions in order to curb global warming. In response to this, the automobile industry is actively developing vehicles with low CO2 emissions, such as hybrid vehicles and electric vehicles.

[0003] Vehicles with low CO2 emissions are becoming more common throughout Japan, and automakers are increasingly contributing to reducing CO2 emissions. However, with many people becoming aware of the progress of global warming, further reductions in CO2 emissions are required.

[0004] For example, there are initiatives underway whereby repair shops that perform vehicle maintenance and repairs can use Green Power Certificates or Non-Fossil Certificates, which allows the amount of CO2 emissions equivalent to the amount of electricity used to be counted as a CO2 reduction, thereby contributing to the reduction of CO2 emissions. There are also initiatives underway where repair shops can use J-Credits to carbon offset their CO2 emissions.

[0005] Another initiative is to use recycled parts instead of new parts, which emit CO2 during their manufacturing, for parts used during maintenance and repairs, in an effort to reduce CO2 emissions not in the automobile itself but in related fields (see, for example, Non-Patent Documents 1 and 2). [Prior art documents] [Non-patent literature]

[0006] [Non-Patent Document 1] JAPADA Report No. 262, "Following the Trends," "JAPRA ~ Establishment of Green Point Club," [online], April 1, 1998, JAPADA (Japan Auto Parts Dealers Association), [Retrieved February 27, 2009], Internet (URL: http: / / japada.org / xpc / modules / japada2 / index.php?content_id=12 ). [Non-patent document 2] Nikkan Jidosha Shimbun, February 4, 2009, p. 14 "Strengthening CO2 Reduction Campaign - JAPRA Fiscal Year 2009 Activity Plan" Summary of the Invention [Problem to be solved by the invention]

[0007] However, as mentioned above, although efforts are being made to popularize vehicles with low CO2 emissions and reduce CO2 emissions, there are also opinions that customers of vehicles with low CO2 emissions do not know what specific steps they should take to further reduce their CO2 emissions. The present invention was made based on these technical challenges, and aims to provide a CO2 reduction management system that can reduce CO2 emissions not only in vehicles but also in related fields, and can instill awareness of the need to reduce CO2 emissions among users. [Means for solving the problem]

[0008] Therefore, the inventor focused on the fact that after a customer purchases a car, the car must be inspected and serviced. In addition to reducing CO2 emissions on these occasions, he thought that by taking advantage of the high penetration rate of automobiles among the general public, he could widely raise awareness of efforts to reduce CO2 emissions when customers visit factories and other business establishments for inspections and maintenance.

[0009] The CO2 reduction management system of the present invention is as follows: a CO2 emission calculation means for calculating CO2 emissions based on the CO2 emission coefficient of the electric power company used by the business establishment and the amount of electricity used by the business establishment; A CO2 reduction calculation means for calculating the amount of CO2 emissions when the business uses environmental value, assuming that the amount of CO2 emissions is the amount of CO2 reduction; It also has a communication unit that transmits the amount of CO2 reduction to the customer's terminal. In this way, when customers request maintenance, repairs, regular inspections, vehicle inspections, etc. from a business, the business can contribute to reducing CO2 emissions by utilizing environmental value. In addition, customers can check the amount of CO2 emissions that have been reduced through the efforts of their business, giving them a real sense of their contribution to reducing CO2 emissions.

[0010] The CO2 reduction calculation means preferably calculates the CO2 reduction amount by regarding the CO2 emissions as the CO2 reduction amount based on the environmental value power amount corresponding to the environmental value and the power consumption amount.

[0011] The amount of environmentally valuable electricity is preferably the amount of electricity certified by a green power certificate.

[0012] The amount of environmentally valuable electricity is preferably the amount of electricity certified by a non-fossil certificate.

[0013] The CO2 reduction calculation means preferably calculates the CO2 reduction amount by regarding the CO2 emissions as the CO2 reduction amount based on the amount of CO2 carbon offset by J-Credit and the CO2 emissions. [Effects of the Invention]

[0014] According to the present invention, by using electricity from the environmental value electricity amount at a business, customers who use the business can feel that they have contributed to CO2 reduction, and it also has an educational effect of making them aware of the importance of CO2 reduction activities. Furthermore, by providing such services, businesses can visualize the environmental value of the services they provide to their customers, and can publicize to society that they are contributing to the preservation of the global environment, the healthy development of the national economy, and the stability of people's lives.

[Figure 3] FIG. 10 is a diagram illustrating an example of a screen displayed by an application used in the embodiment. [Figure 4] FIG. 10 is a diagram showing another example of a screen displayed by an application used in the embodiment. DETAILED DESCRIPTION OF THE INVENTION

[0016] Hereinafter, a management system (CO2 reduction management system) 100 according to an embodiment will be described in detail based on the embodiment shown in the accompanying drawings. The management system 100 is intended for vehicle maintenance workshops as business establishments, and vehicle users who receive services such as vehicle inspections and maintenance at the maintenance workshops. Green Power Certificates, Non-Fossil Energy Certificates, and J-Credits can be used as environmental values. After explaining the first method, which uses Green Power Certificates, we will discuss the second method, which uses Non-Fossil Energy Certificates, and the third method, which uses J-Credits. Examples of business establishments include coffee shops, laundromats, karaoke parlors, agricultural establishments, vending machine retail businesses, the residence of a mobile sales business owner, and the residence of an individual who primarily engages in personal economic activities from the residence. The aforementioned business establishments are merely examples. For example, business establishments of various business types classified by the Japan Standard Industrial Classification are examples of business establishments to which the present invention applies, but the scope of the present invention is not limited to these. By using green power certificates, non-fossil fuel certificates, and J-Credits as environmental value, a business establishment is deemed to have reduced CO2 emissions equivalent to the amount of electricity used.

[0017] [First form] <Use of Green Power Certificates in Repair Shops> By using Green Power Certificates equivalent to the amount of electricity used, a repair shop as a business is considered to have reduced CO2 emissions equivalent to the amount of electricity used. CO2 emissions are calculated by multiplying the amount of electricity used by the CO2 emission coefficient (described below). By using Green Power Certificates as an environmental value, the repair shop contributes to the spread of natural energy equivalent to the amount of electricity (kWh) generated from so-called green power, which does not emit carbon dioxide or other hazardous substances or waste and has a low environmental impact, such as wind, solar, biomass, micro-hydro, and geothermal power, and is considered to have used green power, which helps prevent global warming.

[0018] The repair shop also has a membership system for users, receives registration of information about each member, and provides information appropriate to each member. This information providing means can be the issuance of a membership card, e-mail, a mobile site, a smartphone application (hereinafter referred to as "app"), or the like. In this embodiment, information is provided to each customer registered as a member via an app (CO2 reduction output means) 71. The term "repair shop" refers not only to so-called repair shops that can perform repairs, inspections, maintenance, and vehicle inspections (periodic inspections), but also to auto parts stores that can perform various tasks such as oil changes, and car dealerships that have auto repair departments.

[0019] [Configuration of management system 100: see Figure 1] The schematic configuration of a management system (CO2 reduction management system) 100 that manages the amount of CO2 reduction achieved by a repair shop's efforts to reduce CO2 emissions using green power certificates as environmental value will be described with reference to FIG. As shown in Figure 1, the management system 100 is composed of a factory terminal 10 installed at the maintenance factory, a server 60 in which customer data and the like are stored, a customer terminal 70 which is a portable wireless terminal such as a smartphone, and a network 50 which is a communication network capable of transmitting various types of information between the factory terminal 10, the server 60 and the customer terminal 70 via the Internet, a mobile communication network, a LAN (Local Area Network), etc. The factory terminal 10 comprises a main body 20 installed at the factory, a display unit 41 such as a monitor connected to the main body 20 for displaying information in the form of images, a printing unit 42 such as a printer for outputting information in the form of printouts, and an input unit 43 such as a keyboard or mouse for inputting information.

[0020] [Factory terminal 10: see Figure 1] The factory terminal 10 installed in the maintenance factory is connected to a server 60 via a network 50 such as the Internet to receive input customer data. Although only one factory terminal 10 is shown here, if factory terminals 10 are installed in multiple maintenance factories, the multiple factory terminals 10 will be collectively managed by the management system 100.

[0021] [Main body 20: See Figure 1] The main body 20 automatically executes processing based on a predetermined computer program through cooperation of a CPU 21, a ROM 22, a RAM 23, etc. for executing predetermined processing. The main body 20 also includes a communication unit 24, which is configured with a NIC (Network Interface Card) etc. and is connected to a network 50 by wire or wirelessly, and transmits and receives information to and from the factory terminal 10, the server 60, and the customer terminal 70 via the network 50.

[0022] [Network 50: See Figure 1] The network 50 may be a communication network capable of transmitting various types of information, such as the Internet, a mobile communication network, a LAN (Local Area Network), a WAN (Wide Area Network), an intranet, or the like.

[0023] [Server 60: See Figure 1] The server 60 includes an AP server 61 (CO2 emission amount calculation means, CO2 reduction amount calculation means, communication unit) that executes processing based on information input on the factory terminal 10 side, a business data server 62 that stores business data required for the AP server 61 to execute processing, and a data server 63 that stores a customer database, a CO2 reduction amount Er linked to the customer database, point information, etc. The AP server 61 corresponds to the CO2 emission amount calculation means, CO2 reduction amount calculation means, and communication unit of the present invention.

[0024] The AP server 61 stores a computer program for calculating the CO2 emissions Ef and the CO2 reduction Er. The business data server 62 stores business data required for the AP server 61 to execute various processes. For example, the business data server 62 stores the CO2 emission coefficient C of the electric power company used by the repair shop as necessary business data. The data server 63 stores information input on the factory terminal 10 side by executing API (Application Program Interface) linked processing.

[0025] [Customer terminal 70: see Figure 1] The customer terminal 70 is a portable terminal device, such as a smartphone or tablet, that can acquire CO2 reduction amount and point information via the network 50 and use the points at the repair shop. An application 71 that provides various information to the customer is downloaded to the customer terminal 70, and by executing the application 71, information corresponding to the customer is displayed by the application 71.

[0026] [Functions of the management system 100] The functions of the management system 100 will now be described. As mentioned above, the management system 100 provides a so-called membership system, and provides the application 71 to customers who have registered as members in advance. When registering a customer as a member, the automobile repair shop where the factory terminal 10 is installed obtains the following information (1) and (2) from the customer and stores it in the data server 63.

[0027] (1) Customer information to identify (specify) the customer or to specify the customer's contact information, such as the customer's name, address, telephone number, and email address (2) Customer vehicle information (vehicle information) to identify the customer's vehicle, such as the customer's vehicle registration number, vehicle model, type, and chassis number.

[0028] At this time, the repair shop issues a customer identification code, such as a membership number, to the customer to identify the customer, and the information (1) and (2) above are stored in association with this customer identification code. The customer identification code is also linked to the application 71 of the customer terminal 70. Furthermore, for customers who have already registered, the customer's accumulated points, past shopping information, past maintenance information, etc. can also be stored in the data server 63. The CO2 emissions Ef and CO2 reduction amount Er, which will be described later, can also be stored in the data server 63. The application 71 of the customer terminal 70 can acquire various information such as the CO2 reduction amount Er stored in the data server 63 from the data server 63 via the network 50.

[0029] In addition, the repair shop counts the amount of CO2 reduction Er that occurs when it provides maintenance, vehicle inspection, and other services to the user, and sets a point unit price in advance for each of the maintenance, vehicle inspection, and other services. The unit price of points can be set as follows, for example: (A), (B), (C), or (D). The points acquired can be set according to the amount of electricity used. (A) A point unit price set for each piece of work equipment used for maintenance, inspection, etc., based on the average amount of electricity used per operation. (B) For example, as shown in Table 1, the point unit price is set based on the average amount of electricity used for each task, such as vehicle inspection maintenance, oil change, and tire change. (C) Point unit price set based on the amount of electricity used per unit time. (D) The unit price of points set for each general classification listed on the vehicle inspection certificate. (E) Acquisition points are set according to the actual amount of electricity used.

[0030] For example, Table 1 combines (A), (B), and (D). If a lift is used for maintenance, the point price is set based on the amount of electricity used per lift up and down. Furthermore, for each inspection item in a vehicle inspection, such as side slip, brake inspection, headlight tester, and sound level meter, a point price is set according to the amount of electricity used per inspection. In addition, a point price is set according to the amount of electricity used for peripheral electricity used in maintenance and inspection, such as garage lifts, work lights, fixed lighting, steam lighting, and compressors used for work. Based on these, point prices for each work item, such as vehicle inspection maintenance, engine oil change, and tire change, are set for each vehicle category, such as light vehicles, compact cars, and standard-sized cars.

[0031] [Table 1]

[0032] In the case of (B), the idea is similar to so-called labor cost setting, and a point unit price is set for each work item according to the amount of electricity used. This point unit price can also be set for each vehicle type. In the case of (C), the actual time required for maintenance, inspection, etc. may be calculated, or, as with labor costs, the average amount of electricity used for each work item may be set in advance based on the average time required for each work item, and the point unit price may be set accordingly. In the case of (E), the worker inputs some information into the system when starting and finishing work on each piece of equipment, and the amount of power used is calculated based on the rated power of each piece of equipment and the work time, and the acquisition points are set based on the calculated amount of power used. Setting acquisition points based on the amount of power used will be described in detail in the section on calculating CO2 emissions Ef and acquisition points.

[0033] [Processing by AP server 61: See Figure 2] The AP server 61 stores information about the points set in advance as described above. The AP server 61 then automatically executes the following predetermined processing based on a computer program. Figure 2 shows the flow of the processing executed by the AP server 61.

[0034] First, when a customer receives maintenance at a repair shop, the customer presents app 71 to the repair shop. The repair shop acquires a customer identification code from the customer's app 71 and executes API linkage processing (step S101). By executing the API linkage processing, the customer information, customer vehicle information, etc. of the customer acquired via network 50, as well as the history of maintenance received by the customer at the repair shop and product purchase information, etc. are displayed on display unit 41.

[0035] When a customer leaves their vehicle at a repair shop, the repair shop carries out the work requested by the customer, such as maintenance and vehicle inspection. Then, depending on the work time for each piece of equipment that was performed, for example, if the point setting in (E) above is used, the person in charge inputs the equipment used for the work and the work time using the input unit 43, and executes the API linkage process (step S102). Furthermore, the input contents of the maintenance history information regarding the maintenance items and the dates of the maintenance performed on the customer's vehicle at the repair shop, such as engine oil change, coolant change, brake pad change, regular inspection, vehicle inspection, etc., are stored in the data server 63 via the network 50 by the API linkage in step S102.

[0036] When the AP server 61 receives information input via the input unit 43, it refers to the point conversion standard data stored in the business data server 62 and calculates the CO2 emissions Ef and the customer's acquired points according to the amount of power used G for the work on the customer's vehicle based on the input work content and point unit price (step S103). The means for calculating the CO2 emissions Ef and the acquired points will be described later.

[0037] The AP server 61 receives the input of the CO2 reduction amount Er and the acquired points, along with information such as the maintenance date and maintenance item, and stores the input information in the data server 63. This information is also stored in the data server 63 in association with the customer identification code (step S104). The AP server 61 transmits the CO2 reduction amount Er and the acquired points to the customer's app 71, and the information stored in association with the customer identification code is linked to the customer's app 71 (step S105). In other words, the customer can check the CO2 reduction amount Er and the acquired points, along with information such as the maintenance date and maintenance item, using the app 71 on the customer terminal 70.

[0038] [Calculation method for CO2 emissions Ef and acquired points] A method for calculating the amount of CO2 emissions Ef and the points acquired by the customer according to the amount of power used G in the work on the customer's vehicle will be explained. When the amount of electricity used is G (kWh) and the CO2 emission coefficient per unit of electricity used by the electric power company is C, the relationship with the CO2 emissions Ef is given by the following formula (1). CO2 emissions Ef = electricity consumption G × CO2 emissions coefficient C Equation (1) For this reason, the amount of power used G x CO2 emission coefficient C may be used as the acquisition point as is, or the value obtained by multiplying this by a coefficient (for example, 0.1) may be used as the acquisition point. Here, the CO2 emission coefficient C differs depending on the electric power company used. For example, the CO2 emission coefficient CA of Company A is 0.438 kg-CO2 / kWh, and the CO2 emission coefficient CB of Company B is 0.672 kg-CO2 / kWh. The AP server 61 calculates the CO2 emission amount Ef and the acquired points based on the CO2 emission coefficient C that is stored in the business data server 62 and corresponds to the electric power company used by the repair shop. In this case, when the repair shop uses a green power certificate corresponding to the amount of electricity used G (kWh), the CO2 emissions Ef calculated by formula (1) are regarded as the CO2 reduction amount Er. In other words, when using environmental value, the AP server 61 calculates the CO2 emissions Ef calculated by formula (1) as the CO2 reduction amount Er. The AP server 61 transmits the CO2 reduction amount Er and the acquired points to the customer's application 71.

[0039] [Use of Green Power Certificates] Using a green power certificate as an environmental value means, for example, subtracting the amount of electricity G used by the repair shop from the environmental value amount of electricity Ge1 corresponding to the environmental value certified by the green power certificate held by the repair shop. The environmental value amount of electricity Ge1 refers to the amount of electricity generated by natural energy certified by the green power certificate. Specifically, the serial number of the green power certificate, the expiration date, the environmental value amount of electricity Ge1, the power generation method, etc. are entered via the input unit 43, and various information is stored in the data server 63. The remaining environmental value amount of electricity Ge1A of the green power certificate is calculated by subtracting the amount of electricity G used by the repair shop in performing work on the customer's vehicle from the stored environmental value amount of electricity Ge1, and this is stored in the data server 63. In this case, the following equation (2) is obtained. Residual environmental value power amount Ge1A = Environmental value power amount Ge1 - Power amount used G Equation (2) The remaining environmental value power amount Ge1A corresponds to the environmental value power amount Ge1 when the next power usage amount G is subtracted. When the accumulated power usage amount G is equal to or less than the input environmental value power amount Ge1, the CO2 emissions Ef calculated by formula (1) based on the power usage amount G is regarded as the CO2 reduction amount Er. Furthermore, when the accumulated amount of power usage G exceeds the input environmental value amount of power Ge1, the CO2 emissions Ef calculated by formula (1) based on the amount of power usage G that exceeds the environmental value amount of power Ge1 is not considered as the amount of CO2 reduction Er. Also, the amount that has passed the expiration date is excluded from the environmental value amount of power Ge1.

[0040] [Displayed by App 71: See Figures 3 and 4] Figures 3 and 4 show examples of screens displayed in app 71 showing various information sent from AP server 61 to customer app 71, or information obtained by app 71 via network 50 from data server 63, which stores various information associated with customer identification codes. As shown in Figure 3, the app 71 displays a top screen IM1 that is displayed to the customer, an icon IC1 for accepting an instruction to switch to a screen that displays the customer's CO2 reduction amount, an icon IC2 for accepting an instruction to switch to a screen that displays the CO2 reduction amount of businesses that the customer has used, an icon IC3 for accepting an instruction to switch to a screen that displays the points that the customer has acquired, an icon IC4 for accepting an instruction to switch to a screen that explains the importance of CO2 reduction, and an icon IC5 for accepting an instruction to switch to a screen that displays the customer's customer identification code. When a customer operates icon IC1 in Figure 3, the screen transitions to customer CO2 reduction screen IM2, which displays the customer's CO2 reduction amount as shown in Figure 4(a). When a customer operates icon IC2, the screen transitions to business CO2 reduction screen IM3, which displays the business's CO2 reduction amount as shown in Figure 4(b). When a customer operates icon IC3, the screen transitions to earned points screen IM4, which displays the earned points that the customer has acquired as shown in Figure 4(c). The customer CO2 reduction screen IM2 displays the customer's cumulative CO2 reduction P1, CO2 reduction history P2, CO2 reduction items P3, and CO2 reduction dates P4. The business CO2 reduction screen IM3 displays the business's cumulative CO2 reduction P11 and monthly CO2 reductions for the past 12 months P12. The earned points screen IM4 displays the cumulative earned points P21, earned points earned in the past 12 months P22, and the customer's current earned points P23. Of course, the information displayed by the application 71 is not limited to this, and it is also possible to display so-called shopping points according to the amount paid for purchasing or servicing a product. The points earned through such CO2 reductions can be exchanged for prizes or used as shopping points as mentioned above.

[0041] [Effects of the first form] By looking at the CO2 reduction amount Er and the points acquired, etc. displayed on their own app 71, customers can understand and recognize the amount of CO2 reduction they have achieved by having their vehicle serviced at a repair shop that uses green power certificates, compared to having their vehicle serviced at another repair shop that uses commercial electricity that does not use green power certificates. This allows customers to realize that they have contributed to CO2 reduction, and also has the effect of raising awareness of the importance of CO2 reduction activities. Furthermore, for repair shops, providing such a service allows them to provide better customer service than repair shops that do not use green power certificates, by rewarding customers for their environmental contribution through the use of green power certificates in the form of points based on the degree of contribution made by customers.If the number of customers increases through such services, this will also lead to an increase in CO2 reductions, and CO2 reductions will be achieved in both name and reality.

[0042] [Second form] <Use of non-fossil fuel certificates in repair shops> By using non-fossil fuel certificates (environmental value) corresponding to the amount of electricity used G (kWh), the CO2 emissions Ef calculated by equation (1) are considered to be the CO2 reduction amount Er. Using a non-fossil fuel certificate as environmental value involves subtracting the amount of electricity G used by the repair shop from the environmental value amount of electricity Ge2 corresponding to the environmental value certified by the non-fossil fuel certificate held by the repair shop. The environmental value amount of electricity Ge2 refers to the amount of electricity generated by a non-fossil fuel power source certified by the non-fossil fuel certificate. Specifically, the expiration date and the environmental value amount of electricity Ge2 are input through the input unit 43, and various information is stored in the data server 63. The remaining environmental value amount of electricity Ge2A is calculated by subtracting the amount of electricity G used by the repair shop in performing work on the customer's vehicle from the environmental value amount of electricity Ge2 corresponding to the serial number of the stored non-fossil fuel certificate, and the result is stored in the data server 63. In this case, the following equation (3) is obtained. Residual environmental value power amount Ge2A = Environmental value power amount Ge2 - Power amount used G Equation (3) The remaining environmental value power amount Ge2A corresponds to the environmental value power amount Ge2 when the next power usage amount G is subtracted. When the accumulated power usage amount G is equal to or less than the input environmental value power amount Ge2, the CO2 emissions Ef calculated by formula (1) based on the power usage amount G is regarded as the CO2 reduction amount Er. Furthermore, when the accumulated amount of power usage G exceeds the input environmental value amount of power Ge2, the CO2 emissions Ef calculated by formula (1) based on the amount of power usage G that exceeds the environmental value amount of power Ge2 is not considered as the amount of CO2 reduction Er. Furthermore, the amount that has passed the expiration date is excluded from the environmental value amount of power Ge2.

[0043] The second embodiment also achieves the same effects as the first embodiment.

[0044] [Third form] <Use of J-Credits at repair shops> By using J-Credits (environmental value) corresponding to the amount of electricity used G (kWh), the repair shop can consider the CO2 emissions Ef calculated by formula (1) as the CO2 reduction amount Er. Utilizing J-Credits as environmental value involves, for example, subtracting the CO2 emissions Ef of the repair shop from the CO2 amount Eo that is carbon offset using J-Credits held by the repair shop. Specifically, the CO2 amount Eo to be carbon offset by the J-Credits and other information are entered via input unit 43, and various information is stored in data server 63. The remaining CO2 amount Eo to be carbon offset is calculated by subtracting the CO2 emissions Ef calculated based on the amount of electricity G used by the repair shop in performing work on the customer's vehicle from the CO2 amount Eo to be carbon offset that corresponds to the stored J-Credit serial number, and this is stored in data server 63. In this case, the following equation (4) is obtained. Residual CO2 amount EoA=CO2 amount Eo-CO2 emissions Ef Formula (4) The remaining CO2 amount EoA corresponds to the CO2 amount Eo when the CO2 emissions Ef are next subtracted. When the accumulated CO2 emissions Ef are equal to or less than the input CO2 amount Eo, the CO2 emissions Ef calculated using formula (1) based on the amount of electricity used G is regarded as the CO2 reduction amount Er. In addition, when the accumulated CO2 emissions Ef exceed the input CO2 amount Eo, the CO2 emissions Ef calculated by formula (1) that exceed the CO2 amount Eo is not considered to be the CO2 reduction amount Er.

[0045] The third embodiment also achieves the same effects as the first embodiment.

[0046] In the above embodiment, the configuration of the management system 100, the processing flow, the application 71, etc. are described, but as long as it does not deviate from the gist of the present invention, it is possible to select and discard the configurations described in the above embodiment or to change them to other configurations as appropriate.

[0047] In the above embodiment, a form has been described in which green power certificates, non-fossil fuel certificates, or J-credits are used separately as environmental values, but green power certificates, non-fossil fuel certificates, or J-credits may be used in combination to manage CO2 reduction amounts using the management system 100.

[0048] In the above embodiment, the information input on the factory terminal 10 side is stored in the data server 63 by API linkage, but this is not limiting, and the information may be stored in the data server 63 by file linkage. [Explanation of symbols]
