However, in the prior art, quality control for achieving carbon neutrality has not been established between the first to fourth parties.

For example, it is not established how providers issuing credits for LNG compensate suppliers of LNG to gas utilities for write-off of credits.

In addition, for example, when a supplier supplies LNG to a gas company, the association between LNG and credit (hereinafter sometimes referred to as "linkage") has not been established (prevention of W count etc).

Furthermore, for example, means for gas companies to actively introduce carbon-neutral city gas to end users (e.g. superiority in using carbon-neutral city gas) have not been established.

An object of the present invention is to obtain a carbon-neutral management system and a carbon-neutral management program that enable each party involved in the distribution of carbon-neutral LNG to establish quality management for achieving carbon-neutrality.

The carbon-neutral management system according to the present invention manufactures regulated gas adjusted for use by users from LNG in which depreciation certificate data proving depreciation of greenhouse gases is associated with each receiving unit, A carbon-neutral management system that sorts the depreciation certificate data based on the unit supply amount when supplying to a plurality of users, and adds the sorted depreciation certificate data to the adjusted gas to be supplied to the users. , a receiving unit for receiving the depreciation certificate data; and a receiving unit for producing the regulated gas from the LNG and distributing and supplying it to a plurality of users. a transmission unit for transmitting supply certificate data for proving that the allocated depreciation certificate data is added to the adjusted gas; and a receiving unit of the LNG based on the depreciation certificate data a first verification that monitors and verifies the association of the depreciation certificate data through production of the conditioned gas; and a supply of the regulated gas to the plurality of users based on the supply certificate data. A verification unit that performs a second verification that monitors and verifies the situation before each use, and based on the verification results of the verification unit, the greenhouse gas amortization status based on the amortization certificate data, and the and a management unit that comprehensively manages the usage status of the regulated gas based on the supply certificate data.

According to the present invention, when the receiving unit receives the depreciation certificate data, when producing conditioned gas from LNG and distributing and supplying it to a plurality of users, the transmitting unit supplies it to each user. Supply certificate data for certifying that the allocated depreciation certificate data is added to the adjusted gas is transmitted, which is created according to the supply amount.

In the verification unit, a first verification that monitors and verifies the correspondence state of the depreciation certificate data from the receipt of LNG to the production of regulated gas based on the depreciation certificate data, and based on the supply certificate data A second verification is performed that monitors and verifies conditions from the supply of the conditioned gas to the utilization of each of the plurality of users.

On the other hand, based on the verification result of the verification section, the management section comprehensively manages the greenhouse gas depreciation status based on the depreciation certificate data and the adjusted gas usage status based on the supply certificate data.

As a result, each party involved in the distribution of carbon-neutral city gas can establish quality control for the realization of carbon-neutrality.

In the present invention, part or all of the management of the management unit is executed by the gas company, and third party verification report data, which is the result of verification by a third party verification organization entrusted by the gas company, It is characterized by collating with verification data by the verification unit.

Third-party verification report data, which is the result of verification by a third-party verification organization entrusted by the gas utility, which is partly or wholly managed by the management department, and verification data by the verification department By checking, the accuracy of quality control for achieving carbon neutrality will be improved. Also, the reliability of the supply certificate data can be improved.

In the present invention, the regulated gas is produced by adjusting the calorific value by mixing a regulating gas for dilution or heat increase with the received LNG, and depending on the adjustment amount by the regulating gas is characterized by correcting the depreciation certificate data.

Since no depreciation certificate is attached to the adjusted gas, the depreciation certificate data to be added is corrected according to the amount of the adjusted gas and the amount of all adjusted gas to be supplied. As a result, it is possible to optimize the amount of LNG to be amortized.

In the present invention, when the depreciation certificate data associated with the received LNG includes a mixture of multiple types of depreciation certificate data with different information that guarantees carbon neutrality at a predetermined distribution ratio, the predetermined condition is It is characterized by changing the distribution ratio of the depreciation certificate data attached to the adjusted gas when it is established.

The present invention is characterized in that the predetermined condition is a request from the user to change the distribution ratio of the plurality of depreciation certificate data.

The present invention is characterized in that the predetermined condition is a request to change the allocation ratio of the depreciation certificate data based on the verification result of the verification section.

For the depreciation certificate data associated with LNG, depreciation certificate data with different information that guarantees carbon neutrality, such as means for reducing greenhouse gas emissions, place of implementation, implementation body, etc., is mixed at a predetermined distribution ratio. may have.

Normally, the allocation ratio of depreciation certificate data for received LNG (e.g., one cargo) is maintained and added to the adjusted gas, but if a predetermined condition is met, the depreciation certificate is added to the adjusted gas. Change the distribution ratio of document data.

As one predetermined condition, there is a request to change the distribution ratio of a plurality of amortization certificate data of the user.

Although it depends on the preference of the user, the amount of redemption certificate data can be increased if the request of the user is met.

Further, as another predetermined condition, there is a request to change the allocation ratio of the depreciation certificate data based on the verification result of the verification unit.

In the verification by the verification department, when verifying the implementation status of carbon neutral, if it is not properly operated according to the operation rules, from the next receipt of goods, we will reduce or eliminate the receipt of goods that are not properly operated. to change the allocation ratio of depreciation certificate data applicable to cargo. This can increase the actual implementation rate of carbon neutrality, not just on paper calculations.

In the present invention, when the user uses a plurality of energies together and is running an energy management system that selectively uses them depending on the environment, the execution status information of the energy management system is analyzed and the adjusted gas It is characterized by announcing the evaluation result based on the utilization rate of

By analyzing the execution status information of the energy management system and informing the user of the evaluation result based on the utilization rate of the adjusted gas, it is possible to promote the user's awareness of carbon neutrality.

A carbon-neutral management program according to the present invention causes a computer to operate as the receiving unit, the transmitting unit, the verifying unit, and the managing unit of the carbon-neutral management system.

As described above, according to the present invention, each party involved in the distribution of carbon-neutral LNG can establish quality control for realizing carbon-neutral LNG.

FIG. 1 is a configuration diagram of a carbon-neutral management network built between parties involved in a carbon-neutral management system 10 according to this embodiment.

The carbon neutral management system 10 includes a provider server 12 managed by a provider R1 as a first party, a supplier server 14 managed by a supplier R2 as a second party, and a gas business operator managed by a gas business operator R3 as a third party. It comprises a server 16 and an end-user server 18 managed by end-user R4 as a fourth party.

Provider servers 12 are connected to supplier servers 14 in predetermined group units. The supplier server 14 manages the provider server 12 in units of predetermined groups.

The provider server 12 issues a voluntary credit (hereinafter referred to as an amortization certificate) that certifies the amortization of LNG carbon. The depreciation certificate issued by the provider server 12 is issued for the LNG managed by the provider R1. A collection of issued depreciation certificates is collectively referred to as a “total depreciation certificate”.

A plurality of supplier servers 14 are connected to the carbon-neutral LNG trading network 20 .

The supplier server 14 collects information on LNG and total depreciation certificates notified from a plurality of provider servers 12, distributes LNG according to the transaction status (cargo) of carbon-neutral LNG, and distributes LNG according to the amount of each LNG. Then, an individual depreciation certificate is attached, and transaction processing is executed with the gas supplier server 16 via the carbon-neutral LNG transaction network 20 .

The gas utility server 16 is connected to a plurality of end user servers 18 via a customer management network 22 .

The gas company server 16 is a main server of the carbon-neutral management system 10 according to the present embodiment. In other words, it has a function of mediating between the side that supplies carbon-neutral LNG (provider server 12 and supplier server 14) and the side that consumes carbon-neutral LNG (end-user server 18).

That is, the gas supplier R3 manufactures city gas from the received LNG and supplies the city gas to the end user R4. In the gas supplier server 16, based on the individual depreciation certificate received from the supplier server 14 in association with the supplied city gas, the carbon-neutral city gas that proves that the end user R4 is using carbon-neutral city gas. A supply certificate is issued and communicated to the end-user server 18 via the customer management network 22 .

As a result, in the carbon-neutral management system 10, by issuing a carbon-neutral city gas supply certificate in the gas company server 16, operation as carbon-neutral city gas and a form of carbon-neutral guarantee for city gas are established.

FIG. 2 is a block diagram showing the control system of the gas supplier server 16 that performs the main control of the management of carbon neutrality (in particular, individual depreciation certificate and carbon neutral city gas supply certificate).

The gas company server 16 has a microcomputer 24 . The microcomputer 24 has a CPU 24A, a RAM 24B, a ROM 24C, an input/output port (I/O) 24D, and a bus 24E such as a data bus and a control bus connecting these.

A network I/F 26A and a network I/F 26B are connected to the I/O 24D.

The network I/F 26A is connected to the carbon-neutral LNG trading network 20 (see FIG. 1) and communicates information with the microcomputer 24. FIG.

The network I/F 26B is connected to the customer management network 22 (see FIG. 1) and communicates information with the microcomputer 24. FIG.

Also, the I/O 24D is connected to a large-scale recording medium (for example, hard disk, solid state drive, etc.) 28 for creating and managing total depreciation certificates, individual depreciation certificates, and carbon-neutral city gas supply certificates. store the necessary information in the

Also, regarding the operation of carbon-neutral city gas, if a third-party verification organization 66 (an organization different from the first to fourth parties, see Figure 4) is requested to verify, the third-party verification organization 66 store information about the report (third-party verification report).

That is, the gas supplier server 16 performs verification (verification 1) from the receipt of LNG to the production of city gas, verification (verification 2) from the supply of city gas to the usage status of the end user R4, and third Centrally manages the management of three-party verification reports and the issuance of carbon-neutral city gas supply certificates for carbon-neutral city gas.

According to FIG. 3, time-series processing for delivery of LNG and city gas between parties (provider R1, supplier R2, gas supplier R3, and end user R4), and in synchronization with the time-series processing, Issuance of various certificates (total depreciation certificate, individual depreciation certificate, carbon-neutral city gas supply certificate, and third-party verification report) that are managed in association with LNG and city gas by the carbon-neutral management system 10 , delivery, verification, etc. will be described in detail.

[Provider R1]
Provider R1 issues depreciation certificates (voluntary credits) such as VCS (Verified Carbon Standard), which is the quality and assurance standard for credits generated from greenhouse gas emission reduction and absorption projects, and LNG and depreciation certificates are shipped to the supplier R2 in a state of being linked. Note that, hereinafter, a set of amortization certificates from a plurality of providers R1 received by the supplier R2 will be referred to as a "total amortization certificate".

The data of the total depreciation certificate includes "project name", "serial No.", "credit amount", "credit vintage", "credit type", "depreciation source", " Write-off date” and “tied LNG cargo”.

In addition to sending and receiving data from the provider server 12 to the supplier server 14, the amortization certificate received from each provider R1 can be delivered as a document, for example, as a paper medium amortization certificate 30 (see FIG. 11A). you can go

That is, provider R1's main business is to issue a depreciation certificate for the credit issued by itself. In other words, provider R1, within the scope of the credits it manages, uses amortized issue a certificate;

[Supplier R2]
Supplier R2 sorts the credits issued by a plurality of providers R1 into cargo units for shipping to gas company R3, attaches an individual depreciation certificate equivalent to one cargo received amount to each sorted cargo, and carbon It will be shipped to gas company R3 as neutral LNG.

The data of the individual depreciation certificate includes "project information (name, rate)", "total amount of credit", and "issue date to gas supplier".

In addition, the individual depreciation certificate received from the supplier R2 is sent and received from the supplier server 14 to the gas company server 16, and in addition to the document, for example, the paper individual depreciation certificate 32 (see FIG. 11 (B))). You may pass it as

In other words, supplier R2 mainly sorts into the amount of carbon-neutral LNG requested by gas supplier R3, and distributes and issues individual depreciation certificates according to the sorting.

Sorted carbon-neutral LNG (cargo-based carbon-neutral LNG) may contain different types of voluntary credits (project types).

[Gas company R3]
Gas supplier R3 mainly adjusts the calorific value of carbon-neutral LNG received from supplier R2 (increase heat by inputting combustion gas or dilutes by inputting air), and produces town gas (adjusted Gas), as well as sorting and supplying city gas to the end user R4 in supply units, and on the premise of receiving a third party verification report (details will be described later), carbon-neutral city gas Execute the second task of issuing a supply certificate.

City gas attached with a carbon-neutral city gas supply certificate is positioned as city gas that is guaranteed to be carbon-neutral (carbon-neutral city gas).

Carbon-neutral city gas supply certificate data includes "end user name", "identification number", "supply period", "supply amount", "offset credit amount", and "credit information".

In addition, the carbon-neutral city gas supply certificate issued by the gas company R3 and received by the end user R4 is not only for sending and receiving data from the gas company R3 to the end user R4, but also for the carbon-neutral city in paper form. It may be delivered as a gas supply certificate 34 (see FIG. 11(C))).

In addition, the gas supplier R3 executes the verification work as the third work.

Verification work is classified into the following three verifications (Verification 1 to Verification 3) and executed.

(Verification 1) Verification of operations from receipt of carbon-neutral LNG to production of carbon-neutral city gas

In the specific verification in Verification 1, the set of related documents including the depreciation certificate is referred to, and verification is performed according to the following verification points.

In other words, whether the credits are definitely tied to the received cargo, whether the amount of credits redeemed tied to the cargo is appropriate based on the calculation rules, and whether the credits are redeemed for the gas supplier R3. is verified.

Also, at the receiving plant (base) that receives carbon-neutral LNG, basic information (overview of the base), calorific value adjustment flow, confirmation of known major equipment, confirmation of monitoring points (confirmation of measuring instruments and confirmation of installation positions), Appropriateness of weighing equipment, confirmation of cargo volume determination flow, management system (data collection, recording method), etc. are verified.

(Verification 2) Verification of use by end users R4 from the supply of carbon-neutral city gas

In the specific verification in Verification 2, a set of contracts (demand contract, basic contract, carbon-neutral LNG agreement, memorandum, etc.) and a carbon-neutral LNG management book will be referred to, and verification will be carried out according to the following verification points. be done.

That is, it is verified whether there is any discrepancy between the actual gas usage amount of each end user R4 and the management book, and the basis for calculation of the credit amount and confirmation of the credit amount in the case of an irregular supply form such as lorry supply. .

(Third Party Verification Report)
The third-party verification report is explained in detail below.

A third-party verification agency 66 (see FIG. 4) is requested to determine whether the operation of carbon-neutral city gas is appropriate.

By receiving a verification report (third-party verification report) that refers to international standards from a third-party verification organization 66, end-user R4 can ensure that the operation of carbon-neutral city gas conforms to the calculation rules and is appropriate. It can be proved that there is

With this certification, the reliability of the operation of carbon-neutral city gas will increase compared to the case without certification.

Therefore, in addition to its own verification (Verification 1 and Verification 2), the gas supplier R3 requests the end user R4, who has used carbon-neutral city gas in the past, to receive the third-party verification report issued by the third-party verification organization 66. Based on this document, we will issue a carbon-neutral city gas supply certificate to end user R4.

An example of the third-party verification body 66 is the Japan Quality Assurance Organization, which is a verification body for domestic greenhouse gas (GHG) emissions. At this general incorporated foundation Japan Quality Assurance Organization, the recommendations of the GHG protocol (internationally recognized standards for calculating and reporting greenhouse gas emissions) and the "Specifications for demonstrating carbon neutrality (PA2060: 2010 ISO 14064-3 "Specifications and Guidance on Validation and Verification Rules for GHG Calculations Established by the International Organization for Standardization (ISO)", and Verification is performed in accordance with ISAE 3000 "Standards for Auditing General Non-Financial Information Established by the International Federation of Accountants".

By receiving the third-party verification report data, the gas supplier R3 obtains the basis for issuing the carbon-neutral city gas supply certificate data.

The third-party verification report received from the third-party verification reporting organization shall be a third-party verification report in writing, for example, paper media, in addition to the transmission and reception of data from the third-party verification reporting organization to gas supplier R3. 36 (see FIG. 11(D)).

[End User R4]
End user R4 mainly performs business using carbon-neutral city gas supplied from gas supplier R3.

In this case, the carbon-neutral city gas supply certificate attached to the carbon-neutral city gas can be used to appeal that the carbon-neutral city gas is being used.

The use of the carbon-neutral city gas by the end user R4 is verified by the verification 2 of the gas supplier as to whether the carbon-neutral city gas is being used appropriately and effectively.

(Management and control of various certificates according to LNG distribution)

FIG. 4 is a functional block diagram categorized by function regarding issuance processing control at each party, handover processing control between parties, and verification processing control after issuance, mainly based on the various certificate data explained in FIG. . Note that each block shown in FIG. 4 does not limit the hardware configuration of each, and part or all of the processing may be performed by executing a software program.

As shown in FIG. 4, the provider server 12 has a credit management unit 38 and notifies a depreciation certificate issuing unit 40 of whether or not credit is required for the LNG to be shipped, and of an instruction to issue a credit if credit is required.

The depreciation certificate issuing unit 40 issues a depreciation certificate and sends it to the receiving unit 44 of the supplier server 14 via the sending unit 42 . As a result, the supplier server 14 collects the depreciation certificates linked to each LNG receiving unit (total depreciation certificate).

The reception unit 44 is connected to the carbon-neutral LNG construction unit 46 and sends the received total depreciation certificate to the carbon-neutral LNG construction unit 46 .

The carbon-neutral LNG constructing unit 46 receives from the LNG management unit 48 shipping information of LNG in cargo units for shipping to the gas company R3.

The individual depreciation certificate issuing unit 50 is notified of this shipping information and the linking information between each depreciation certificate aggregated as a total depreciation certificate and each receiving unit of LNG.

Based on the shipping information and the linking information, the individual depreciation certificate issuing unit 50 issues an individual depreciation certificate per cargo for the LNG per cargo to be shipped to the gas company R3. In this case, when LNG per cargo becomes a plurality of receiving units, a plurality of individual depreciation certificates will be attached.

The individual depreciation certificate issuing unit 50 is connected to the information sending unit 52 . The information sending unit 52 sends the individual depreciation certificate information issued by the individual depreciation certificate issuing unit 50 to the information receiving unit 54 of the gas company server 16 .

The information reception unit 54 is connected to the verification unit 56 and transmits the amortization certificate information received from the information transmission unit 52 of the supplier server 14 to the verification unit 56 .

The verification unit 56 is also connected to a carbon-neutral city gas management unit 58 .

The carbon-neutral city gas management department 58 handles distribution from receipt of carbon-neutral LNG to production and supply of carbon-neutral city gas, including receipt of LNG, production of city gas by heating or dilution, and supply to end users R4. Batch management.

Management information managed by the carbon-neutral city gas management unit 58 is sent to the verification unit 56 .

The verification unit 56 executes the aforementioned verification 1 and verification 2 based on the management information at the time of distribution of the carbon-neutral city gas and the amortization certificate information.

Here, a third-party verification report receiving section 60 is connected to the verification section 56 . The third-party verification report receiving unit 60 is a proof that the proper operation has been certified as a result of the verification of the appropriateness of the operation of carbon-neutral city gas by the end user R4, which was requested by the third-party verification organization 66 in the past. Receive a third party verification report.

The third-party verification report received by third-party verification report receiving section 60 is sent to verification section 56 .

The verification unit 56 is connected to a carbon-neutral town gas supply certificate issuing unit 62 . The verification unit 56 supplies the carbon-neutral city gas supply certificate to the carbon-neutral city gas supply certificate issuing unit 62 based on the existence of the third-party verification report together with the verification results of the first and second verifications. Notify to issue a certificate.

The third-party verification report may not be required as the basis for issuing a carbon-neutral city gas supply certificate. can further increase the reliability of

A carbon-neutral city gas supply certificate issuing unit 62 issues a carbon-neutral city gas supply certificate, and transmits carbon-neutral city gas supply certificate information to the end user via a carbon-neutral city gas supply certificate sending unit 64. Notify R4.

Based on the notified carbon-neutral city gas supply certificate information, the end user R4 posts, for example, a paper medium carbon-neutral city gas supply certificate 34 (see FIG. 11(C)) or displays it on a display medium. By using carbon-neutral city gas, it is possible to appeal that it is contributing to the reduction of greenhouse gases.

The operation of this embodiment will be described below with reference to the flow charts of FIGS. 5 to 10. FIG.

At step 100, depreciation certificate information is acquired from the provider server 12, then the process proceeds to step 102, based on the order received from the gas company server 16, the LNG is sorted into one cargo receiving amount of LNG, and the process proceeds to step 104.

In step 104, individual depreciation certificate information corresponding to the amount of one cargo received is issued, then the process proceeds to step 106 to ship the carbon neutral LNG accompanied by the individual depreciation certificate information, and this routine ends.

FIG. 6 is a control flow chart showing a main routine for carbon neutral management in the gas supplier server 16 (third party) in FIG.

At step 200, a carbon-neutral LNG receiving management control process is executed, at step 300, a carbon-neutral city gas supply management control process is executed, at step 400, a credit type ratio adjustment control process is executed, and at step 500, a carbon A neutral city gas supply certificate operation support control process is executed, and this routine ends. Detailed processing of each subroutine of steps 100, 200, 300, and 400 will be described below with reference to FIGS. 7 to 10. FIG.

FIG. 7 is a flow chart showing the detailed flow of the gas supplier server carbon-neutral LNG receiving management control subroutine of step 200 of FIG.

At step 202, it is determined whether or not carbon-neutral LNG has arrived, and if the determination is negative, this routine ends.

If the determination in step 202 is affirmative, the process proceeds to step 204 to extract carbon neutral information (for example, individual depreciation certificate information, etc.) from the incoming documents.

In the next step 206, verification (verification 1 shown in FIG. 3) from receipt of goods to manufacturing is performed, and the process proceeds to step 208. FIG.

In step 208, as a result of verification 1, it is determined whether or not the system is being properly operated. If the determination is negative, it is determined that the operation is improper, and the process proceeds to step 210 to execute improper operation processing. and the routine ends. Inappropriate operation processing includes, for example, returned goods due to incomplete documentation, equipment failure due to heat increase or dilution, and the like.

Also, if the determination in step 208 is affirmative, the process proceeds to step 212 to provide the carbon neutral information to the third party verification agency 66 to request third party verification, and then the process proceeds to step 214 .

At step 214, the production of carbon-neutral city gas is instructed. At this point, the carbon-neutral LNG will be heated or diluted to produce carbon-neutral city gas.

FIG. 8 is a flow chart showing the detailed flow of the gas supplier server carbon-neutral city gas supply control subroutine in step 300 of FIG. This routine is executed in a state where carbon-neutral city gas is produced by heating or diluting carbon-neutral LNG.

In step 302, the status of linkage between carbon-neutral city gas and individual supply certificates is acquired, and in step 304, carbon-neutral city gas is shipped according to the ratio of individual supply certificate types set for each supply destination. After sorting by quantity, the process proceeds to step 306 .

In step 306, the supply of carbon-neutral city gas is instructed, the process proceeds to step 308, verification from manufacture to supply (verification 2 shown in FIG. 3) is performed, and the process proceeds to step 310.

In step 310, as a result of the verification 2, it is determined whether or not the operation is properly performed. If the determination is negative, it is determined that the operation is improper, and the process proceeds to step 312 to execute improper operation processing. and the routine ends. Inappropriate operation processing includes, for example, inadequate documents such as contracts, and inadequate comparison of administrative numerical values with actual values.

Also, if the determination in step 310 is affirmative, the process proceeds to step 314 to determine whether or not the third party verification report information has been acquired as a result of requesting the third party verification agency 66 . If a negative determination is made in step 314, it is determined that the operation is inappropriate, the routine proceeds to step 312, the inappropriate operation process is executed, and this routine ends. In this case, the inappropriate operation processing includes, for example, suspension of issuance of a carbon-neutral city gas supply certificate.

If the determination in step 314 is affirmative, the process proceeds to step 316 to issue a carbon-neutral city gas supply certificate. output, the routine exits.

The processing of step 314 (necessity of third-party verification report information) is processing when the acquisition of third-party verification report information is used as an essential basis for issuing a carbon-neutral city gas supply certificate. If there is, and acquisition of third party verification report information is not essential, step 314 may be omitted.

The flow chart of FIG. 9 is for the end user R4, which is executed when the management control is smoothly performed, in addition to the main management control such as issuance of a carbon-neutral city gas supply certificate in the carbon-neutral management system 10. Positioned as service processing.

At step 400, it is determined whether or not the end user R4 has requested to change the allocation of the amortization certificate.

If the determination in step 400 is affirmative, the process proceeds to step 402 to acquire the allocation rate of the depreciation certificate of the request destination (end user R4), and the process proceeds to step 408 .

If a negative determination is made in step 400, the process proceeds to step 404 to determine whether or not there is a request for changing the distribution ratio based on the verification evaluation result. If an affirmative determination is made in step 404 , a specified allocation rate based on the verification result is obtained in step 406 and the process proceeds to step 408 .

If the determination in step 404 is negative, this routine ends.

At step 408, the allocation rate of the default depreciation certificate is read, then the process proceeds to step 410 to correct the allocation rate, and the routine ends.

As a result, the needs of the end user R4 can be met by changing the allocation rate of the amortization certificate at the request of the end user R4. In addition, by lowering the allocation rate of the depreciation certificate with a low verification evaluation, the evaluation can be raised.

FIG. 10 is a flow chart showing the detailed flow of the carbon-neutral city gas supply certificate operation support control subroutine in step 500 of FIG.

In step 502, a list of end users to whom the carbon-neutral city gas supply certificate is issued is obtained, and the process proceeds to step 504.

At step 504, the energy input source of end user R4 is analyzed. This analysis is possible by BEMS (Building Energy Management System) information analysis. BEMS is a system intended for office buildings, commercial facilities, etc. In this embodiment, it is assumed that the end user is a building manager, so BEMS is used. Each EMS (energy management system) information should be analyzed.

In the next step 506, evaluation processing of the analysis result is executed, and the process proceeds to step 508 to notify the evaluation result.

As a result, the gas supplier R3 can independently verify the energy management of the end user R4 (whether necessary and sufficient carbon-neutral city gas is being used, etc.) and, for example, provide appropriate advice to the end user R4. be able to.

In the present embodiment, the market for realizing carbon neutrality is the first party (provider R1), the second party (supplier R2), the third party (gas supplier R3), and the fourth party (end user R4) was exemplified separately, but one party may concurrently serve two or more tasks assigned to each party.

For example, the business of the third party (gas supplier R3) (purchase of carbon-neutral LNG) and the business of the fourth party (end user R4) (supply of electricity using carbon-neutral city gas for power generation, etc.), A case in which one party performs both of the tasks falls under the category of the carbon-neutral management system described in the present embodiment.
