It is characterized by correcting the depreciation certificate data.

Since the depreciation certificate is not attached to the adjusted gas, the depreciation certificate data to be added is corrected according to the amount of all adjusted gas to be supplied according to the amount of adjusted gas. As a result, it is possible to optimize the amount of LNG to be proved to be depreciated.

In the present invention, when a plurality of types of depreciation certificate data different from each other in the information guaranteeing carbon neutrality are mixed in the depreciation certificate data associated with the received LNG at a predetermined distribution ratio, a predetermined condition is satisfied. When it is established, the distribution ratio of the depreciation certificate data attached to the adjusted gas is changed.

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

The present invention is characterized in that the predetermined condition is a case where there is a request for changing the distribution ratio of the depreciation certificate data based on the verification result of the verification unit.

The depreciation certificate data associated with LNG is a mixture of depreciation certificate data with different information that guarantees carbon neutrality, such as means for reducing greenhouse gas emissions, implementation location, implementation entity, etc., at a predetermined allocation ratio. May be.

Normally, the distribution ratio of the depreciation certificate data of the received LNG (for example, one cargo) is maintained and added to the adjusted gas, but if certain conditions are met, the depreciation certificate to be added to the adjusted gas. Change the distribution ratio of book data.

One predetermined condition is a case where there is a request to change the distribution ratio of a plurality of depreciation certificate data of a user.

Although it depends on the user's preference, the amount of depreciation certificate data can be increased if the user's wishes are met.

In addition, as another predetermined condition, there is a case where there is a request to change the distribution ratio of the depreciation certificate data based on the verification result of the verification department.

[Provider R1]
Provider R1 issues depreciation certificates (voluntary credits) such as VCS (Verified Carbon Standard), which is the quality and guarantee standard for credits generated from greenhouse gas emission reduction and absorption projects, and is accompanied by LNG and depreciation certificates. Will be shipped to supplier R2 in the state of being tied. In the following, a collection of depreciation certificates by a plurality of providers R1 received by the supplier R2 is referred to as a "total depreciation certificate".

The data of the total depreciation certificate is the "project name", "serial number", "credit amount", "credit vintage", "credit type", "depreciation source", and "depreciation source" for specifying each depreciation certificate. Includes "depreciation date" and "linked LNG cargo".

Further, the depreciation certificate received from each provider R1 is delivered as a document, for example, a paper depreciation certificate 30 (see FIG. 11A), in addition to sending and receiving data from the provider server 12 to the supplier server 14. You may go.

That is, the main business of the provider R1 is to issue a depreciation certificate for the credit issued by the provider R1. In other words, Provider R1 is amortized to ensure that it is tied to a given environmental protection project (climate change, biodiversity, local employment expansion, financial independence, etc.) within the scope of credits it manages. Issue a certificate.

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

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

Further, the individual depreciation certificate received from the supplier R2 is a document, for example, an individual depreciation certificate 32 in a paper medium (see FIG. 11B), in addition to sending and receiving data from the supplier server 14 to the gas company server 16. As a result, delivery may be performed.

That is, the main business of the supplier R2 is to sort the amount of carbon-neutral LNG required by the gas company R3, and to distribute and issue an individual depreciation certificate according to the sorting.

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

[Gas operator R3]
The gas company R3 mainly adjusts the calorific value of the carbon-neutral LNG received from the supplier R2 (heat increase by inputting combustion gas or diluting by inputting air), and city gas (adjustment) having an amount of heat suitable for the end user R4. Carbon-neutral city gas on the premise of the first business of manufacturing gas) and sorting and supplying city gas into supply units for supplying to end user R4, and receiving a third-party verification report (details will be described later). Perform the second task of issuing a supply certificate.

A city gas with a carbon-neutral city gas supply certificate is positioned as a city gas with a guaranteed carbon-neutrality (carbon-neutral city gas).

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

Further, the carbon-neutral city gas supply certificate issued by the gas company R3 and received by the end user R4 is a carbon-neutral city in writing, for example, in a paper medium, in addition to sending and receiving data from the gas company R3 to the end user R4. It may be delivered as a gas supply certificate 34 (see FIG. 11 (C)).

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

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

(Verification 1) Verification of operation from receiving carbon-neutral LNG to manufacturing carbon-neutral city gas

In the specific verification in the verification 1, the verification is executed according to the following verification points with reference to the set of related documents including the depreciation certificate.

That is, is the credit definitely tied to the received cargo, is the amount of credit depreciated tied to the cargo an appropriate amount based on the calculation rules, and the credit is depreciated for the gas company R3. It is verified whether it is.

In addition, at the receiving factory (base) that receives carbon-neutral LNG, basic information (outline of the base), calorific value adjustment flow, confirmation of known main equipment, confirmation of monitoring points (confirmation of measuring instrument and confirmation of installation position), The appropriateness of the measuring instrument, confirmation of the flow of determining the cargo handling amount, and the management system (data collection, recording method), etc. are verified.

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

FIG. 4 is a functional block diagram classified by function with respect to issuance processing control between the parties, transfer processing control between the parties, and verification processing control after issuance, based on the various certificate data described in FIG. .. Note that each block shown in FIG. 4 does not limit the hardware configuration thereof, and some 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 the depreciation certificate issuing unit 40 of the necessity of credit and the issuance instruction when credit is required for the LNG to be shipped.

The depreciation certificate issuing unit 40 issues a depreciation certificate and sends it to the reception unit 44 of the supplier server 14 via the sending unit 42. As a result, the depreciation certificate associated with each LNG receiving unit is aggregated in the supplier server 14 (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 construction unit 46 receives shipping information of LNG in cargo units for shipment from the LNG management unit 48 to the gas company R3.

The shipping information and the information associated with each depreciation certificate aggregated as a total depreciation certificate and each LNG receiving unit are notified to the individual depreciation certificate issuing unit 50.

The individual depreciation certificate issuing unit 50 issues an individual depreciation certificate for each cargo to the LNG for each cargo to be shipped to the gas company R3 based on the above shipping information and the association information. In this case, if the LNG of the cargo unit 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 transmitting unit 52. The information transmission unit 52 transmits 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 verification unit 56 executes the above-mentioned verification 1 and verification 2 based on the management information at the time of distribution of carbon-neutral city gas and the depreciation certificate information.

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

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

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

The third-party verification report does not have to be the basis for issuing the carbon-neutral city gas supply certificate, but by using the third-party verification report as the basis for issuance, the carbon-neutral city gas supply certificate can be used. The reliability of the can be further increased.

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

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

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

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

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

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

In step 200, the carbon-neutral LNG receiving management control process is executed, in step 300, the carbon-neutral city gas supply management control process is executed, in step 400, the credit type ratio adjustment control process is executed, and in step 500, carbon is executed. The neutral city gas supply certificate operation support control process is executed and this routine ends. Hereinafter, detailed processing of each subroutine of step 100, step 200, step 300, and step 400 will be described with reference to FIGS. 7 to 10.

FIG. 7 is a flowchart showing a detailed flow of the gas operator server carbon neutral LNG consignment management control subroutine in step 200 of FIG.

In step 202, it is determined whether or not carbon neutral LNG has arrived, and if a negative determination is made, this routine ends.

If affirmative judgment is made in step 202, the process proceeds to step 204 to extract carbon neutral information (for example, individual depreciation certificate information) from the arrival document.

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

In step 208, as a result of verification 1, it is determined whether or not the operation is proper, and if it is negative, it is determined that the operation is inappropriate, and the process proceeds to step 210 to execute the improper operation process. And this routine ends. Improper operation processing includes, for example, returns due to incomplete documents, equipment defects due to heat increase or dilution, and the like.

Further, if affirmative determination is made in step 208, the process proceeds to step 212, carbon neutral information is provided to the third party verification organization 66, a third party verification is requested, and the process proceeds to step 214.

Step 214 directs the production of carbon-neutral city gas. At this point, the carbon-neutral LNG is heated or diluted to produce carbon-neutral city gas.

FIG. 8 is a flowchart showing a detailed flow of the gas operator server carbon neutral city gas supply control subroutine in step 300 of FIG. It should be noted that 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 associative status of the carbon-neutral city gas and the individual supply certificate is acquired, and then in step 304, the carbon-neutral city gas is shipped according to the ratio of the individual supply certificate type set for each supply destination. Sort by quantity and proceed to step 306.

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

In step 310, as a result of verification 2, it is determined whether or not the operation is proper, and if it is negative, it is determined that the operation is inappropriate, and the process proceeds to step 312 to execute the improper operation process. And this routine ends. Improper operation processing includes, for example, inadequate documents such as contracts, and inadequate collation with actual values in management.

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

If affirmative judgment is made in step 314, the process proceeds to step 316 to issue a carbon-neutral city gas supply certificate, and then the process proceeds to step 318 to certify the carbon-neutral city gas supply to the end user server 18. The book is printed and this routine ends.

The process of step 314 (necessity of third-party verification report information) is a process 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 no requirement to acquire the third party verification report information, step 314 may be omitted.

FIG. 9 is a flowchart showing a detailed flow of the credit type ratio adjustment control subroutine in step 400 of FIG.

The flowchart 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 the carbon neutral city gas supply certificate in the carbon neutral management system 10. It is positioned as a service process.

In step 400, it is determined whether or not the end user R4 has requested to change the distribution of the depreciation certificate.

If an affirmative determination is made in this step 400, the process proceeds to step 402, the allocation rate of the depreciation certificate of the request destination (end user R4) is acquired, 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 to change the allocation rate based on the verification evaluation result. If an affirmative determination is made in step 404, the designated allocation rate based on the verification result is acquired in step 406, and the process proceeds to step 408.

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

In step 408, the allocation rate of the default depreciation certificate is read, and then the process proceeds to step 410 to execute the allocation rate correction process, and this routine ends.

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

FIG. 10 is a flowchart showing a 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 acquired, and the process proceeds to step 504.

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

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

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

In the present embodiment, as the market for realizing carbon neutrality, the first party (provita R1), the second party (supplier R2), the third party (gas operator R3), and the fourth party (end user) Although R4) is illustrated separately, one party may concurrently perform two or more duties assigned to each party.

For example, the business of the third party (gas company R3) (purchase of carbon-neutral LNG) and the business of the fourth party (end user R4) (supplying power by using carbon-neutral city gas for power generation, etc.). The case where one party executes both of the above is also a category of the carbon neutral management system described in the present embodiment.
