Description

The present invention relates to an emission totaling device, an emission totaling method, and a program.

Curbing the emission of greenhouse gases such as _CO2 , which is considered to be one of the causes of global climate change, is an urgent issue today. In order to effectively curb greenhouse gas emissions, each country and company is assigned a quota for emissions of greenhouse gases such as _CO2 . Emissions trading schemes (also called “emissions trading schemes”, but in this specification the term “emissions trading” is used here), which are schemes for trading emission allowances between countries and companies, have been introduced in various countries. It is In recent years, due to changes in the global environment, there has been a recognition that the reduction of greenhouse gas emissions must be further accelerated. On the other hand, there is a growing demand for the promotion of carbon neutrality through participation in emissions trading.

When participating in emissions trading, it is necessary to properly count the greenhouse gases emitted by each participant in order to maintain fairness among participants and the soundness of the emissions trading market. For example, in Patent Literature 1, a company's greenhouse gas (GHG) emissions are calculated based on account items, item names, item names, and corresponding basic unit information. In addition, for example, in Patent Document 2, in order to prevent unfair recording of emissions when purchasing goods, in electronic payment, the payment amount and emissions are set based on the payment amount, the use of the purchased item, and the corresponding _CO2 emissions. It is proposed to allow settlement if it is below the upper limit.

Japanese Patent No. 6864404 JP 2010-244345 A

However, Patent Literature 1 does not specifically mention how to deal with the case where there are unclear items in the account titles, items, and product names in terms of GHG emission calculation. In addition, in Patent Document 2, it is not determined whether the use of the purchased item is appropriate as a target for accounting for CO ₂ emissions. In order to enable even small and medium-sized enterprises, in which it is difficult to allocate additional personnel for emissions trading, to participate in emissions trading, appropriate aggregation of greenhouse gas emissions is required. There is a demand for a mechanism that can be implemented as simply as possible.

In order to solve the above problems and other problems, one of the objects of the present invention is to enable organizations such as companies to easily calculate appropriate greenhouse gas emissions by using accounting data. It is to provide an emissions totaling device, an emissions totaling method, and a program.

One aspect of the present invention acquires accounting data generated for a business operator from a business operator participating in greenhouse gas emissions trading, and accounts included in the accounting data or expense items included in each account , Determine whether there are any unclear account items or expense items from the viewpoint of calculating greenhouse gas emissions, and if it is determined that there are unclear account items or expense items, records related to the relevant account items or expense items from the said business operator , and calculates the amount of greenhouse gas emissions corresponding to each account item or expense item based on the record.

According to the present invention, an organization such as a company can easily calculate an appropriate amount of greenhouse gas emissions by using accounting data.

In the emissions tallying system S shown in FIG. Based on this, the amount of greenhouse gas emissions emitted by an organization such as a company to which each business operator terminal device 2 belongs is aggregated. Since greenhouse gas emissions are calculated based on the accounting data recorded by each organization, the calculated emissions are highly reliable. In the accounting data, if it is unclear whether it is appropriate as basic data for calculating emissions, or if it is deemed unclear in terms of calculating emissions, the receipts that are the basis of the account and expenses The reliability of the data on the calculated emissions is ensured because the emission amount calculation is based on reference to document data such as bills and statements of delivery. In addition, the calculated greenhouse gas emissions are adjusted as necessary based on the results of periodic audits of the underlying accounting data. This also ensures the reliability of the greenhouse gas emissions calculated for the organization. The emissions totaling device 1 may be configured as an independent device for totalizing emissions, or may be used to trade greenhouse gas emissions totaled from terminal devices 2 of each business operator and other terminal devices in the emissions trading market M. may be provided as part of an emissions trading intermediary system that performs In any case, the greenhouse gas emissions totaled by the emissions totaling device 1 can be traded on the emissions trading market M.

In this specification, for the sake of simplicity, "greenhouse gas" is hereinafter referred to as "CO ₂ ", which is a typical component. In addition, for simplicity, the amount of greenhouse gas emissions received by the emissions totaling device 1 from each business operator will be referred to as " _CO2 emissions (if unclear, simply "emissions")" or "emissions allowance". I decided to.

<Emission amount aggregation device 1>
FIG. 2 illustrates, as a block diagram, the hardware configuration and functions of the emissions tallying device 1 of this embodiment. In FIG. 2, the emission totaling device 1 includes a processor 11 such as a CPU and GPU, a memory 12 having storage devices such as ROM and RAM, an auxiliary storage unit 13 having storage devices such as HDD and SSD, a keyboard, a touch panel, and a mouse. , an input device such as a microphone, an input/output unit 14 having an output device such as a monitor display, a speaker, a printer, etc., a data interface unit (data IF unit) 15 for transmitting and receiving data between hardware units, and communication with the network 3 is provided with a communication unit 16 for performing

The operator terminal device 2, which will be described later, can also be basically configured as a computer having the hardware configuration illustrated in FIG.

Next, the functions of the emission totaling device 1 according to this embodiment will be described with reference to FIG. 2 as well. The emissions totaling device 1 has functional blocks of an emissions management unit 121 , an emissions verification unit 122 , and an emissions trading unit 123 . These functional blocks are realized by executing corresponding programs by the processor 11 of FIG. can be configured as

The data used by the above functional blocks are stored in data storage areas provided in the auxiliary storage unit 13, namely, the operator emissions storage unit 131, the emissions trading storage unit 132, the operator information storage unit 133, and the emissions calculation unit. are stored in the data storage unit 134 for use. As exemplified in FIG. 2, the business operator emission amount storage unit 131, the emission trading storage unit 132, the business information storage unit 133, and the emission amount calculation data storage unit It is stored corresponding to the operator terminal device 2 owned by each operator. This is for grasping the amount of CO ₂ emissions for each business operator who owns the business operator terminal device 2 . Each data storage area will be described later with an example.

The emissions management unit 121 has a function of calculating, aggregating, and recording CO ₂ emissions data for each business operator. The CO ₂ emissions calculated for each business operator's terminal device 2 are stored in the business operator's emission storage unit 131 .

In this embodiment, the CO ₂ emissions data recorded by the emissions management unit 121 is calculated based on the accounting data generated and recorded by the business operator who owns each business operator terminal device 2. be. Accounting data is specifically books and documents recorded using accounting software or the like. As is well known, in the ledger, the expenditures of businesses are recorded by sorting them into account items and expense items. The emission amount management unit 121 calculates the CO ₂ emission amount by using the unit CO ₂ emission amount corresponding to each item based on these account items and expense items.

FIG. 4 shows a configuration example of the business operator emission storage unit 131. As shown in FIG. In the enterprise emission storage unit 131 illustrated in FIG. 4, CO ₂ emissions are recorded corresponding to account items and expense items included in the accounting data of the enterprise. Now, refer to the example of the emission amount calculation data storage unit 134 in FIG. Unit emissions data used by the emissions management unit 121 to calculate CO ₂ emissions are recorded in the emissions calculation data storage unit 134 . For example, the electricity used is recorded in units of g/kWh and the corresponding _CO2 emissions in units of g/km in the case of rail transport. The emission amount management unit 121 calculates the CO ₂ emission amount corresponding to the expenditure recorded in the accounting data by multiplying the quantity of each expense item by the unit emission amount in FIG.

It should be noted that this is not a problem if the account items and expense items of the accounting data record quantities that can be used to calculate emissions. It may not be possible to perform an emissions calculation. In such a case, the emissions management unit 121 can, for example, coordinate with the accounting software used by the business operator to create accounting data, so that documents related to items for which emissions cannot be calculated (invoices, receipts, statements of delivery, etc.) Evidence documents, etc.) can be used to obtain the quantity required for calculating emissions. It is more preferable if the documentary evidence to be referred to is converted into text data through OCR processing or the like. For example, if only the payment amount is recorded in the accounting data for the gasoline cost of a company car, the emissions management unit 121 refers to the documentary evidence linked to the cost item to determine the amount of gasoline refueled (liter ) can be obtained and the _CO2 emissions can be calculated using this quantity and the corresponding unit _CO2 emissions per liter of gasoline. CO ₂ emissions calculated based on accounting data in this way are highly reliable data with solid grounds, and are suitable for emissions trading.

The emissions verification unit 122 checks the results of financial audits conducted at fixed intervals, such as every six months, on the _CO2 emissions of each business operator calculated based on the accounting data by the emissions management unit 121. Perform processing to add corrections by Even CO ₂ emissions calculated based on accounting data may include CO ₂ emissions associated with the use of vehicles that should be excluded from the ledger for private use, for example. When such a problem in the book is corrected by an _accounting audit, in the present embodiment, the emissions verification unit 122 refers to the results of the accounting audit to Make any necessary corrections to emissions. Such corrections will make the _CO2 emissions data recorded by operator more reliable.

The emissions trading unit 123 executes emissions trading based on the CO ₂ emissions data recorded in the business operator's emissions storage unit 131 for each business operator. The emissions trading unit 123 may directly access the system of the emissions trading market M (FIG. 1) via the network 3 to conduct transactions, or may conduct transactions via another system that mediates emissions trading. you can go A record of emissions trading by the emissions trading unit 123 is stored in the emissions trading storage unit 132 . FIG. 6 shows an example of the emissions transaction storage unit 132. As shown in FIG. In the example of FIG. 6, the emission transaction storage unit 132 records the purchased emission amount and the sold emission amount. , purchased/sold quantity, and purchased/sold amount are recorded.

The business operator information storage unit 133 stores, as business operator information, data used by the emission totaling device 1 for calculating and totaling the CO ₂ emissions of each business operator. FIG. 7 shows an example of the business operator information storage unit 133. As shown in FIG. The business operator information storage unit 133 illustrated in FIG. 7 stores terminal identification information (e.g., terminal ID, password, etc.) that serves as identification information when each business operator terminal device 2 connects to the emissions totaling device 1, emission total Items such as accounting data linkage information for the device 1 to access the accounting data of each business, owned vehicle information used for calculating emissions related to movement in company cars, energy contract information such as electricity, financial institution transaction information, etc. Recorded. Regardless of the above example, the business operator information storage unit 133 may appropriately record information necessary for emission amount calculation. For example, the accounting data linkage information may include linkage information for directly accessing the accounting software, accounting service system, etc. used by each business operator to acquire necessary data.

According to the business operator terminal device 2 described above, each business operator can execute emissions trading or consider measures for reducing emissions, based on _CO2 emission data calculated based on accounting data. can be easily implemented.

<Data processing by emission totaling device 1 and business operator terminal device 2>
Next, the data processing executed by the emissions counting device 1 and the business operator terminal device 2 in this embodiment described above will be described. It should be noted that the business operator terminal device 2 provides data necessary for emission calculation in response to access from the emission calculation device 1 in the phase of emission calculation processing, and receives the calculated emission data. function of the operator terminal device 2 alone is omitted.

<<Data processing by the emission totaling device 1>>
Data processing executed by the emission totaling device 1 having the configuration and functions described above will be described with reference to FIG. FIG. 9 is a flow chart showing an example of data processing by the emissions tallying device 1. As shown in FIG. The emission totaling device 1 acquires the accounting data of each business from the business terminal device 2 owned by each business participating in the emission totaling system S (FIG. 1) of this embodiment, and stores the acquired accounting data. Perform basic data processing to calculate highly reliable CO ₂ emissions data based on the data.

Referring to FIG. 9, the emission management unit 121 of the emission totaling device 1 executes the following processing steps S2 to S8 for each business operator terminal device 2 in step S1. In the data processing of FIG. 9, it is assumed that the business operator terminal device 2 has already performed the login processing necessary for exchanging data with the emission totaling device 1 .

In step S<b>2 , the emissions management unit 121 acquires accounting data from the accounting data storage unit 231 for one business operator terminal device 2 . At this time, instead of accessing the business terminal device 2 as described above, the accounting data may be obtained by directly accessing the accounting software, accounting service system, or the like that created the accounting data. The timing of acquisition of the accounting data may be, for example, the time when the accounting data for the month is recorded after the monthly accounting deadline.

In step S3, the emission amount management unit 121 determines whether or not there is an unknown item in calculating the CO ₂ emission amount in the account items and expense items of the acquired accounting data. If it is determined that there is an unknown item (YES in step S3), in step S4, the emissions management unit 121 accesses the accounting data storage unit 231 of the business operator terminal device 2 and determines that it is related to an unknown item. Acquire documentary evidence data to be provided. As described above, the documentary evidence data is data related to documentary evidence such as invoices, receipts, statements of delivery, statements of accounts, etc. Text data generated from each documentary evidence through OCR processing, etc., or text data of each documentary evidence Digital data in an appropriate format such as image data can be used. The emissions management unit 121 links unknown items based on the date, issuer, item, quantity, and other data contained in the documentary evidence, and calculates the quantitative data necessary for calculating emissions. can be obtained. Alternatively, in the accounting data, it is also possible to store documentary evidence data that supports unknown items in a form that is linked in advance to each account item and each expense item. Thereafter, the emission amount management unit 121 proceeds to data processing in step S5. Even if it is determined in step S3 that there is no unknown item, the emission amount management unit 121 similarly proceeds to data processing in step S5.

In step S5, the emissions management unit 221 calculates the _CO2 emissions using the data stored in the emissions calculation data storage unit 134 for each account item and expense item of the accounting data, Record in the storage unit 131 .

In step S<b>6 , the emission amount management unit 121 determines whether or not the accounting data storage unit 231 of the business operator terminal device 2 contains audit results, which are the results of the accounting audit for the business operator. If it is determined that there is no inspection result (NO in step S6), the emission management unit 121 proceeds to data processing in step S8. If the emissions management unit 121 determines that there is an audit result (YES in step S6), in step S7, the emissions management unit 121 refers to the audit result, and in step S5 calculates the CO ₂ emissions. Investigate whether or not the accounting data used for this purpose has been corrected, and correct the calculation results of _CO2 emissions if necessary. After that, the discharge amount management unit 121 proceeds to data processing in step S8. Revisions to emissions based on the results of these accounting audits are made each time an accounting audit is conducted, such as every fiscal year or every half year. You may do so.

In step S8, the emission amount management unit 121 notifies the operator's terminal device 2 of the aggregate result of the CO ₂ emissions, and ends the series of data processing for one operator's terminal device 2. FIG.

In step S<b>9 , the emission amount management unit 121 determines whether an instruction to end data processing has been received through the input/output unit 14 . If there is an instruction to end the data processing (YES in step S9), the emission amount management unit 121 ends this data processing. If there is no instruction to end the data processing (NO in step S9), the emission amount management unit 121 returns to step S1 and continues the calculation and aggregation processing of the CO ₂ emission amount for each operator's terminal device 2. FIG. According to such data processing, the emission totaling device 1 calculates and totals the CO ₂ emissions based on the accounting data in each business operator's terminal device 2 , and at the same time, transmits the CO ₂ emissions data to each business operator's terminal device 2 . Quantity aggregate results can be provided. Calculation of CO ₂ emissions for each operator's terminal device 2 is automatically executed based on the accounting data, and the audit results of the accounting data are also reflected in the calculation results. It is possible to obtain highly reliable _CO2 emissions data. Further, although detailed description is omitted here, each business operator can execute emissions trading based on the CO ₂ emissions obtained from the emissions totaling device 1 .

The latest monthly CO ₂ emissions of which the business operator's terminal device 2 is notified from the emission totaling device 1 are displayed in the monthly CO ₂ emissions display section 271 . In the example of FIG. 10, CO ₂ emissions are aggregated and displayed, for example, for each account item of accounting data. Emissions can be displayed in various forms, such as displaying more detailed expense items and graphing changes in monthly aggregated values. Based on the _CO2 emissions totaled by the emissions totaling device 1, the emissions transaction operation unit ₂₇₂ displays the _CO2 emissions that can be sold and the unit price for purchase. is provided. By inputting in the sales desired emission amount input field within a sellable range and operating the sales button, the sales procedure for the CO ₂ emission amount can be easily performed from the operator's terminal device 2 . For example, the emission amount that can be sold can be obtained and presented as the difference between the calculated and aggregated CO ₂ emissions amount and the emission allowance by letting the emission calculation device 1 grasp the emission allowance for each business operator. . Conversely, if the actual emissions exceed the allowance, the company can be asked to provide the emissions that need to be purchased.

A cancel button 273 is provided to execute processing for canceling display and operation on this screen.

According to such a display screen of the operator's terminal device 2, each operator can quantitatively grasp the amount of CO ₂ emissions and its transition. In addition, emissions trading can be easily carried out based on the calculated and aggregated emissions.
