Description

Technical Field

[0001] The present invention belongs to the technical field of carbon accounting for environmental protection enterprises, and specifically relates to a carbon accounting data management method and system for environmental protection enterprises. Background Art

[0002] Due to the characteristics of the industry, environmental protection companies usually involve a variety of sub-business areas, such as waste incineration power generation, sewage treatment, biomass power generation, hazardous waste / solid waste treatment, etc. There are many types of business and collaborative processing projects are more common, such as collaborative treatment of garbage and hazardous waste, collaborative treatment of food sludge, and distributed photovoltaics within the factory.

[0003] At present, environmental protection enterprises use carbon accounting for themselves mainly for the following purposes: 1. Carbon verification and disclosure, clarifying the positive / zero / negative carbon attributes of the enterprise through accounting, assisting in the formulation and achievement of green and low-carbon goals, and meeting the increasingly stringent carbon emission disclosure requirements of the stock exchange for listed companies, such as publishing corporate sustainability reports (ESG), annual reports of listed companies, S&P green scores, etc.; 2. Carbon asset certification, applications for various types of carbon emission rights transactions require carbon accounting review before certification and carbon accounting verification during the process, such as applying for certified voluntary emission reductions (CCER), certified carbon reduction standards (VCS) carbon emission rights trading certification, etc. After certification, you can participate in the carbon emission rights trading market to obtain benefits; 3. Carbon footprint certification, it is necessary to calculate the carbon emissions of each link in the product supply chain. After obtaining certification, you can increase the added value of the product and overcome international trade barriers.

[0004] The above types of carbon accounting have different uses. Even for the same business type, there are differences in data statistical caliber, accounting factors and formulas. They must be implemented according to the recognition standards issued by authoritative certification agencies. In recent years, the recognition standards have been continuously updated. Therefore, enterprises usually conduct carbon accounting for a certain purpose separately. However, the above carbon accounting has similar processes in the implementation management process. They all need to go through the following steps: ① Collect activity data during the production and operation of the project, ② Configure accounting formulas and accounting factors, ③ Calculate carbon emissions or carbon offsets during the collection period, ④ Submit application reports and supporting materials, ⑤ Adjust data or application reports based on the audit results, and ⑥ Conduct carbon verification and accounting regularly after certification. Therefore, enterprise carbon accounting management can be divided into accounting formula and factor management, activity data collection and management, application report and certification management, etc.

[0005] Since the single application process is long and requires repeated verification of data, enterprises usually entrust third-party institutions to assist in carbon accounting offline. According to the accounting purpose to be applied for, corresponding data collection forms are formulated, and project operators collect various types of activity data related to production and operation, and third-party institutions perform accounting and write application reports. Environmental protection enterprises usually involve multiple subdivided business types and there are problems with collaborative processing. It is difficult for third-party institutions to accurately divide the actual collection scope of project activity data. The simple superposition of various types of business methodologies is prone to repeated calculations, missing data items, and too many and redundant collection items. In addition, there are many projects in environmental protection enterprises, and third-party institutions lack in-depth understanding of the actual situation of the projects. Project operators lack knowledge of carbon accounting, which leads to cumbersome and inefficient report review and verification modification processes.

[0006] The invention with patent publication number CN118014531A discloses a data collection method, device, electronic device and readable storage medium based on carbon accounting. However, this method does not take into account the particularity of multi-business collaboration in the environmental protection industry, and is only applicable to industries other than the environmental protection industry. The data collected based on industry type is prone to duplicate calculations, missing data items, and too many collection items. In addition, this method is difficult to handle the problem of multiple accounting and recognition uses for the same business, lacks collection data quality management and carbon accounting result recognition and certification management, and its carbon accounting results lack authority and practicality.

[0007] The invention with patent publication number CN115409669A discloses a carbon emissions accounting method, device and storage medium. This method removes duplication and improves efficiency in carbon accounting formula configuration and accounting parameters, and can be applied to a variety of industry types. However, it does not remove duplication and improve efficiency in activity data collection, and there are problems such as repeated calculation of collected activity data, missing data items, and too many collection items. In addition, this method also lacks collection data quality management and carbon accounting result identification and certification management.

[0008] The invention with patent publication number CN116957503A discloses a carbon emission reduction project management system, which is applicable to projects of a single industry type. The data of its project information data module comes from the basic information formed by due diligence on the project, and it is difficult to constrain the data accuracy; the output is related application documents and reports, and there is a lack of management of the identification and verification process, and its report lacks authority.

[0009] The invention with patent publication number CN117291778A discloses a method and system for calculating carbon emission data. This method directly collects activity data by adding new detection equipment. However, on the one hand, the activity data that can be directly collected is limited and cannot meet the requirements of carbon accounting. For example, data such as transport vehicle numbers, mobile source fuel consumption, and airplane travel cannot be directly collected. In addition, the directly collected data already exists in the production management system, which is a duplicate collection and has a high cost. On the other hand, the accounting results have no recognition and verification process and lack authority.

[0010] The invention with patent publication number CN118134114A discloses an integrated carbon asset management system for carbon footprint calculation and supply chain management. However, it solves the data quality problems of various supply chains. The type of activity data directly collected is single and limited, and cannot be applied to multiple business scenarios; and there is a lack of management of identification and verification processes, and its reports lack authority. Summary of the invention

[0011] In response to the technical problems of low activity data quality, low data utilization, large accounting deviation, and complex and inefficient management processes in the process of environmental protection enterprises' carbon accounting application certification and verification for multi-business collaboration and multiple recognition purposes, the present invention discloses a carbon accounting data management method and system for environmental protection enterprises, which can solve the problems of repeated calculations, missing data items, and excessive and redundant collection items that occur in the implementation of existing methods, and reduce the dependence of environmental protection enterprises on third-party institutions during the implementation of carbon accounting.

[0018] S6, converting the verified initial activity data field table to be modified into a standard activity data field table and an actual activity data field table in sequence, and modifying the actual activity data field table; and proceeding to step S5.

[0019] As a preferred example, step S1 further includes:

[0020] Determine the types of uses for each project involved in carbon accounting, determine the activity data fields required to be collected for each business type based on the latest certification standards and rules published by the authoritative certification agency for the corresponding use, and summarize the activity data field tables of various types involved in a single business type to obtain the initial activity data field table;

[0021] The initial activity data field table has a three-layer data structure: the first layer is for accounting purposes, marking all activity data required for a certain purpose; the second layer is for data classification, and the classification principle is determined according to the calculation boundary of the accounting methodology corresponding to the accounting purpose; the third layer is for all activity data required to calculate carbon emissions or carbon offsets in each scope.

[0031] The attached data refers to the supporting evidence of all data sources including production and operation data, electricity data, fixed source fuel consumption, mobile source fuel consumption, transportation data, domestic waste composition data, general industrial solid waste composition data, and aircraft travel data.

[0032] As a preferred example, in step S2, the following formula is used to perform the same field verification between the standard activity data field tables of different projects of the same business type:

[0033]

[0034] Where η represents the maximum deviation ratio allowed for the same field in the standard activity data field table, E s1 Indicates any production operation data in the standard activity data field table to be proofread, E sn Indicates the production operation data of the corresponding item in the average standard activity data field table, E x1 Indicates that any item in the standard activity data field table to be proofread is not E s1 Field, E xn The corresponding item of the average standard activity data field table is not E sn field.

[0035] As a preferred example, in step S3, the following formula is used to check the filling of each field in the actual activity data field table through historical data:

[0036]

[0037] Wherein, η' represents the maximum deviation ratio allowed for the same field in the current actual activity data field table and the historical actual activity data field table, and E' s1 Indicates any data in the current actual active data field table, E' sh Represents the data of the corresponding item in the historical actual activity data field table, E' x1 Indicates the field to be proofread in the current actual active data field table, E' xh Represents the corresponding fields of the historical actual activity data field table.

[0038] As a preferred example, in step S5, the activity data of each type of business and each accounting purpose in the initial activity data field table are calculated in combination with corresponding accounting factors and accounting formulas to obtain corresponding carbon accounting results.

[0040] The accounting formula and factor management module configures corresponding accounting formulas and accounting factors for various types of businesses and accounting methodologies for various purposes involved in the project company;

[0041] The activity data collection and management module collects and processes the activity data according to the input accounting request, generates an initial activity data field table; and converts the initial activity data field table, the standard activity data field table and the actual activity data field table after each data modification;

[0042] The application report and verification management module combines the activity data in the initial activity data field table with the corresponding accounting factors and accounting formulas to perform carbon accounting, organizes the accounting results into an application report and submits it, and at the same time organizes the questionable data of the rejected report, marks the corresponding fields in the initial activity data field table, and recalculates and submits the report for the modified activity data

[0043] Beneficial effects:

[0044] First, the environmental protection enterprise carbon accounting data management method and system of the present invention effectively reduces the workload of project companies in filling out reports. In the process of converting between the initial table, standard table, and actual table, repeated fields, statistical calibers, data classifications, etc. are optimized, avoiding the increase in workload caused by multiple filling out and multiple trainings of project companies, and reducing time and labor costs.

[0045] Second, the environmental protection enterprise carbon accounting data management method and system of the present invention improves the accuracy of activity data.

[0052] The following examples will enable those skilled in the art to more fully understand the present invention, but are not intended to limit the present invention in any way.

[0053] The present invention discloses a method for managing carbon accounting data for an environmental protection enterprise, the method comprising the following steps:

[0054] S1, determine the activity data fields that need to be collected for each business type according to the types of business types involved in carbon accounting of each project company, and obtain the initial activity data field table for each accounting purpose of each business type after summarizing;

[0055] S2: De-duplicate and classify the activity data in the initial activity data field table according to the actual business, and mark the fields that are the same but have different statistical calibers to form a standard activity data field table;

[0057] S4, fill in the actual activity data field table;

[0058] S5, converting in sequence to obtain the corresponding standard activity data field table and the initial activity data field table; performing carbon accounting, report writing and submitting for review based on the initial activity data field table; if the review is passed, the process ends, otherwise it proceeds to step S6;

[0059] S6, converting the verified initial activity data field table to be modified into a standard activity data field table and an actual activity data field table in sequence, and modifying the actual activity data field table; and proceeding to step S5.

[0060] The present invention manages the circulation, transformation, calibration, and modification of activity data during the carbon accounting process of various types of businesses and uses of environmental protection enterprises, thereby improving the efficiency of the overall carbon accounting process and the accuracy of the results. The implementation process is divided into five steps from S01 to S05, such as Figure 1 shown.

[0061] S01 Initial Activity Data Field Table

[0062] First, environmental protection companies need to determine the types of uses for each project participating in carbon accounting, such as ESG requires the participation of all projects, CCER only projects that meet the constraints can participate, etc. After determining the purpose of carbon accounting, according to the latest certification standards and rules published by the authoritative certification agency for the corresponding purpose, according to each project type (such as waste incineration power generation, sewage treatment, etc.), determine the activity data fields that need to be collected for each type (in the methodology, the data that needs to be collected during the accounting period for calculation in addition to the accounting factors is called activity data). The various types of activity data field tables involved in a single project company are summarized to obtain the initial activity data field table, hereinafter referred to as the "initial table".

[0063] The initial table has a three-layer data structure: the first layer is the accounting purpose, which marks all the activity data required for the purpose; the second layer is the data classification, and the classification principle is determined according to the accounting methodology corresponding to the accounting purpose, that is, it is divided according to the calculation boundaries in the methodology, usually using scope 1 (direct carbon emissions), scope 2 (indirect carbon emissions caused by energy), scope 3 (other indirect carbon emissions), carbon offset, etc.; the third layer contains all the activity data required to calculate the carbon emissions or carbon offsets in each scope.

[0064] The data of a certain use activity in the initial table can be directly calculated to obtain the corresponding carbon accounting results when combined with the corresponding accounting factors and accounting formulas.

[0065] S02 Standard Activity Data Field Table

[0066] The activity data in the initial table stores the activity data for various accounting purposes of a certain type of business. For the same type of business, there must be duplicate data items in the activity data for various accounting purposes. Therefore, we seek common ground while reserving differences and remove duplicates, classify and categorize the activity data in the initial table according to the actual business to form a standard activity data field table, hereinafter referred to as the "standard table". The conversion between the initial table and the standard table is shown in the figure below. Figure 2 shown.

[0067] The data in the standard table is classified according to the actual business situation. The redundant fields are removed for completely identical fields, and the fields that are identical but have different statistical calibers are not deduplicated, but are marked. According to the general situation of the environmental protection industry, it can be classified into several categories: production and operation data, power data, fixed source fuel consumption, mobile source fuel consumption, transportation data, domestic waste composition, general industrial solid waste composition, airplane travel, accessories, etc.

[0068] Among them, production and operation data refers to the characteristic data of a certain business, such as the amount of garbage entering the factory / furnace, the amount of external heat / steam, and the inlet and outlet water indicators of the waste incineration business; the sewage treatment volume, inlet and outlet water COD volume, inlet and outlet water total nitrogen TN volume, etc. of the sewage treatment business; the biomass treatment volume, external heat / steam volume, etc. of the biomass treatment business; the hazardous waste incineration treatment volume, and the hazardous waste comprehensive utilization treatment volume of the hazardous waste disposal business.

[0069] Electricity data refers to purchased electricity, comprehensive plant electricity consumption, power generation, grid-connected electricity, and self-generated and self-used electricity; fixed source fuel consumption refers to the fuel consumption of fixed sources such as incinerators, pumps, engines, boilers, and canteen natural gas, including diesel, gasoline, natural gas, liquefied petroleum gas, and biogas; mobile source fuel consumption refers to the fuel consumption of mobile sources such as official vehicles and mobile machinery, including diesel, gasoline, natural gas, liquefied petroleum gas, and biogas; transportation data refers to the data that environmental protection companies entrust third-party vehicles to transport from the collection point / initial point to the project company or to external transportation, such as Types of third-party garbage transportation, slag transportation, fly ash transportation, sludge transportation, etc. include data such as the number of transportation vehicles, average transportation distance, and transportation weight; the composition of domestic waste refers to the domestic waste composition table data that the waste incineration plant regularly entrusts a third party to test; the composition of general industrial solid waste refers to the general industrial solid waste composition table data that the solid waste treatment plant regularly entrusts a third party to test; air travel refers to employee air travel data, including the codes of the starting and ending airports, cabin type, number of people, etc.; attachments refer to supporting evidence for all the above data sources, such as signed production monthly reports, environmental protection monthly reports, test reports, financial forms, etc.

[0070] The standard table contains the accounting purpose data of the same business type, and has been deduplicated, classified and labeled according to the actual situation. Therefore, the same fields can be proofread between standard tables containing different items of the same business type. The proofreading principle is that the activity data fields of the same business type should be basically consistent with the production operation data ratio. If the deviation value is too large, it may indicate that there is a possibility of misreporting, as shown in formula (1).

[0071]

[0072] Where η represents the maximum deviation ratio allowed for the same field in the standard activity data field table, E s1Indicates any production operation data in the standard activity data field table to be proofread, E sn Indicates the production operation data of the corresponding item in the average standard activity data field table, E x1 Indicates that any item in the standard activity data field table to be proofread is not E s1 Field, E xn The corresponding item of the average standard activity data field table is not E sn field.

[0073] S03 Actual Activity Data Field Table

[0074] The standard table contains all the activity data for each accounting purpose of a certain type of business. However, for project companies of environmental protection enterprises, due to the characteristics of the industry, there is often the situation of coordinated disposal of waste, that is, a single project has multiple business types, and the fields of the standard table are inconsistent with the site, which is prone to under-reporting or over-reporting. Therefore, the standard tables of multiple business types of the project company are integrated, and the different fields in each standard table are retained. The same fields are divided into two layers of data, total amount and component, and converted into an actual activity data field table that conforms to the actual situation on site, hereinafter referred to as the "actual table". The conversion between the actual table and the standard table is shown in the figure below. Figure 2 shown.

[0075] The field division of the actual table is the same as that of the standard table, but some repeated fields have a two-layer structure of total amount and component. For example, for waste incineration power generation and catering kitchen coordination, the waste treatment volume and catering kitchen treatment volume are independent fields, and the comprehensive electricity consumption of the plant is the same field, which is divided into the total comprehensive electricity consumption of the plant, the comprehensive electricity consumption component of the waste incineration power plant and the comprehensive electricity consumption component of the catering kitchen treatment plant. The former is the sum of the latter two.

[0076] The actual table is a form filled in directly by the project company, which clarifies the statistical caliber of the data in each field and is consistent with the actual situation on site. For projects with stable operation, the fields in the actual table are basically unchanged. Therefore, the filling of each field in the actual table can be proofread through historical data. The proofreading principle is that the data fields of each activity of the same project should have the same trend as the data of previous years. Fields with abnormal proportions may represent the situation of misreporting, as shown in formula (2).

[0077]

[0078] Wherein, η' represents the maximum deviation ratio allowed for the same field in the current actual activity data field table and the historical actual activity data field table, and E' s1 Indicates any data in the current actual activity data field table (generally representative production operation data), E' sh Represents the data of the corresponding item in the historical actual activity data field table, E' x1 Indicates the field to be proofread in the current actual active data field table, E'xh Represents the corresponding fields of the historical actual activity data field table.

[0079] S04 Carbon accounting, reporting and verification

[0080] The relationship between the initial table, standard table and actual table has been determined based on the carbon accounting purposes required by environmental protection enterprises and the collaboration of various project business types. The three tables can be converted sequentially or reversely, and the field data of each table is synchronized in real time, without the need for manual conversion of projects.

[0081] When the project completes the filling of the actual table, the corresponding initial table can display all the activity data required for each type of business and each accounting purpose involved, and the carbon accounting results for this purpose can be calculated in combination with the accounting factors of the corresponding methodology. The carbon accounting results are used to write the corresponding application report, which is submitted to the verification agency for review. Only after the review is the report authoritative, it can obtain a certificate and participate in public disclosure or trading markets.

[0082] S05 data problem feedback and correction

[0083] After submitting the application report to the certification body, the authenticity, statistical and accounting rationality of the activity data during the inclusion period in the report need to be reviewed multiple times. If there is doubt about some of the data in the report, the report will be rejected and modified. At this time, the questionable activity data needs to be marked in the initial table and synchronized to the actual table. The project company will explain, modify and submit the questionable data. The modified data will also be synchronized to the initial table and can be submitted again after calculation. Repeat the process until the report is certified.

[0084] According to the principle and process of this method, a system is designed to implement this method. The system function diagram is as follows: Figure 3 The system is divided into the calculation formula and factor management module, the activity data collection and management module, and the application report and certification management module.

[0085] Accounting formula and factor management module: This module is maintained by dedicated personnel from environmental protection enterprises and configures accounting methodologies for various types of businesses and purposes involved. Each methodology includes three parts: accounting formula, accounting factors, and activity data, among which activity data participates in the initial table summary.

[0086] Activity data collection and management module: This module is responsible for activity data collection, automatic conversion between different tables, data labeling and reminders, etc. The project company will fill in the data and the accounting results will be fed back and labeled to form a closed loop.

[0087] Application report and verification management module: This module is responsible for carbon accounting by combining the activity data in the initial table with the corresponding factors and accounting formulas. The accounting results are organized into an application report and submitted. At the same time, the questionable data of the rejected report is organized, the corresponding fields in the initial table are marked, and the modified data is recalculated and the report is submitted.

[0088] Examples

[0089] A certain environmental protection enterprise has business types such as domestic waste incineration power generation, general industrial solid waste treatment, hazardous waste disposal, biomass power generation and sewage treatment, and participates in carbon accounting for ESG sustainable development reports, VCS, etc. Among them, Project Company A has two businesses, domestic waste incineration power generation and general industrial solid waste treatment, both of which participate in ESG sustainable development report carbon accounting, and domestic waste incineration power generation participates in VCS. Project Company B has domestic waste incineration power generation business, participates in ESG sustainable development report carbon accounting but does not participate in VCS.

[0090] According to the corresponding methodology, the initial activity data field tables of each business unit of Project Company A are organized as shown in Table 1 and Table 2.

[0091] Table 1 Initial table of municipal solid waste incineration

[0092]

[0093] Table 2 Initial table of general industrial solid waste treatment

[0094]

[0095] The initial business tables of Project Company A are organized into standard tables as shown in Tables 3 and 4.

[0096] Table 3 Standards for incineration of domestic waste

[0097]

[0098]

[0099] Table 4 General industrial solid waste standards:

[0100]

[0101] After completing the data collection, the standard table of domestic waste incineration business of Project Company A and Project Company B (as shown in Table 5) can be used to check whether there is any misreporting (based on the domestic waste treatment volume, the detection of domestic waste components is relatively random and no comparison is made).

[0102] Table 5

[0103]

[0104] Assuming that the maximum deviation ratio is 0.3, it can be seen from the above table that the deviation ratio of the purchased electricity data of project company B is too large, and there is a high probability of misreporting. This field needs to be marked and checked and reviewed by the project company.

[0105] The two business standard tables of Project Company A are integrated into actual tables as shown in Tables 6 and 7.

[0106] Table 6

[0107]

[0108] Table 7

[0109]

[0110] Based on this actual table, the project company can intuitively fill in various data to avoid errors and omissions.

[0111] After completing the data collection, the current actual table of Project Company A can be checked against the historical actual table data to determine whether there is any misreporting (based on the amount of domestic waste treatment, the components of domestic waste and solid waste are more random and therefore not compared). The results are shown in Tables 8 and 9.

[0112] Table 8

[0113]

[0114] Table 9

[0115]

[0116] Assuming that the maximum deviation ratio is 0.3, it can be seen from Table 8 that the deviation ratio of the leachate wastewater weight data in the current actual table of Project Company A is too large, and there is a high probability of misreporting. The field needs to be marked and checked and reviewed by the project company.

[0117] If during the ESG certification report review process, the review experts have questions about the Scope 2 accounting results of Project Company A's waste incineration business, they need to mark the Scope 2 purchased electricity field in the initial table of Project Company A's waste incineration business and convert it to the purchased electricity-domestic waste incineration component in the actual table of Project Company A, and the project company will provide additional explanations or modifications.

[0118] The above are only preferred embodiments of the present invention, and the protection scope of the present invention is not limited to the above embodiments. All technical solutions under the concept of the present invention belong to the protection scope of the present invention. It should be pointed out that for ordinary technicians in this technical field, some improvements and modifications without departing from the principle of the present invention should be regarded as the protection scope of the present invention.
