Description

Technical Field

[0001] The present invention relates to a greenhouse gas auditing system and method, and more particularly to a greenhouse gas auditing system and method that can save a great deal of manpower and time, simplify the operation process, and accelerate the on-site verification operation time, and can be used for 100% activity data and carbon coefficient auditing operations. Background Art

[0002] At present, greenhouse gases (GHG) or greenhouse effect gases refer to the gas components in the atmosphere that contribute to the greenhouse effect. Humans use a large amount of fossil fuels such as coal and oil, which produce carbon dioxide (CO2) when burned and are emitted into the atmosphere. The aforementioned carbon dioxide is one of the greenhouse gases, and others include ozone (O3) and methane (CH4). This also allows the atmosphere to absorb more radiation from the earth, so the earth is getting hotter and hotter. According to model predictions, as more and more fossil fuels are consumed worldwide, the average surface temperature may rise by 2°C to 6°C by the end of the 21st century. Therefore, only by quickly and effectively reducing greenhouse gas emissions at this moment, otherwise the earth's climate system will not be able to suppress warming and the subsequent butterfly effect.

[0003] As greenhouse gases cause surface warming and lead to extreme climate phenomena, the United Nations calls for urgent carbon reduction actions. "Net zero carbon reduction" has become a common global issue. More than 110 countries around the world have declared that they will achieve the goal of net zero greenhouse gas emissions by 2050 (some countries in 2060). Therefore, companies cannot stay out of carbon reduction plans. Failure to implement greenhouse gas inventories and formulate carbon reduction strategies may affect the competitiveness of operations. However, it is not easy for companies to reduce carbon or achieve zero carbon. They must first introduce greenhouse gas inventories before setting reduction targets and implementing reduction strategies to achieve the goal of carbon neutrality.

[0004] The existing greenhouse gas inventory method is mainly manual. The inventory process is as follows: Figure 1 As shown, at least the following steps are included: 1. The inspected unit 1 provides the first version of the consolidated inspection report and inspection list to the inspected unit 2.

[0005] 2. The inspected unit 2 conducts a document review of the first version of the compiled inspection report and inspection list; if there are no problems, it will directly go to the inspected unit 1 to review the original data on site; if preliminary problems or matters that need to be clarified are found, they will be returned to the inspected unit 1 for modification.

[0006] 3. The inspected unit terminal 1 provides the second version of the consolidated inspection report and inspection list to the inspected unit terminal 2.

[0007] 4. The inspection unit 2 conducts a document review of the second version of the inspection report and the inspection list; and directly conducts the first on-site review of the original data (S1) at the inspected unit 1. If there is no problem, it means it is qualified and the certification process is carried out. If the data is incorrect or needs to be clarified, an inspection report is issued to the inspected unit 1 for reply, and before the next stage of on-site verification, a new inspection report and inspection list are made and given to the inspection unit 2.

[0008] 5. The inspected unit 1 provides the third edition of the consolidated inspection report and the inspection list to the inspected unit 2.

[0009] 6. The inspection unit terminal 2 conducts a document review of the third edition of the inspection report and the inspection list; and directly conducts a second on-site review of the original data (S2) at the inspected unit terminal 1. If there is no problem, it means it is qualified and the certification process is carried out; if the data is incorrect or needs to be clarified, an inspection report is issued to the inspected unit terminal 1 for reply, and before the next stage of on-site verification, a new inspection report and inspection list are prepared and given to the inspection unit terminal 2.

[0010] The existing greenhouse gas audit method may require different on-site review processes (S1~SN) depending on the complexity of the organizational field or product composition, and each session may require multiple verification teachers to participate (1~multiple people) in the on-site verification work. The verification procedure is carried out by manually sampling 10%~20% or the original data that meets the verification requirements. Therefore, a lot of time is required to prepare and confirm the verification data.

[0011] In view of this, the applicant, through continuous research and experimentation, came up with the idea of ​​designing a greenhouse gas auditing system and method, which can save a lot of manpower and time, simplify the operation process, speed up the on-site verification operation time, and can be used for 100% activity data and carbon coefficient auditing operations.

DETAILED DESCRIPTION

[0029] Please also see Figure 2 and Figure 3 , and cooperate with Figure 4 , which is a system architecture diagram of the present invention, a carbon emission calculation diagram of direct and / or indirect emission sources, and a list diagram of greenhouse gas inventory data sources. As shown in the figure, the system architecture of the present invention includes at least one audit unit terminal 3, and multiple audited unit terminals 5 connected to the audit unit terminal 3 via a communication network 4. Among them, the audit unit terminal 3 includes at least an accounting organization and product carbon emission numerical module 31, an audit report and inventory module 32, a major emission source activity data sampling module 33, an OCR character recognition module 34 and an interactive platform module for sampling data verification 35, and an inventory audit database 36.

[0030] The carbon emission numerical module 31 for calculating the organization and products mainly calculates the carbon emission of all direct and / or indirect emission sources of the audited unit 5 based on the calculation scope of the organization boundary 311 and the operation boundary 312. The calculation method is as follows: Figure 3 The carbon emission calculation diagram of the direct and / or indirect emission sources can be roughly presented, among which the subsidiaries 52 (Company A to Company D) under the parent company 51 of the audited unit end 5 are the calculation scope of the organizational boundary 311; and the ships, power generation units, owned and / or controlled buildings, fleets, rented factories, etc. of each subsidiary 52 are the calculation scope of the operating boundary 312. Product audit is based on the ISO 14067 carbon footprint specification to calculate the carbon emissions directly and / or indirectly generated by the product throughout its life cycle. The monitoring calculation method is roughly as follows: 1. Direct monitoring method: Directly monitor the exhaust concentration and flow rate to measure greenhouse gas emissions.

[0031] 2. Mass balance method: Balance calculation of the input, output, generation, consumption and conversion of material mass and energy in the process.

[0032] 3. Emission coefficient method: Emissions = appropriate activity intensity data × emission coefficient × GWP.

[0033] At this stage, the emission coefficient method is mainly used to calculate various carbon emissions. This module uses artificial intelligence to check the correctness of the inventory data and whether the adopted coefficients are reasonable. It also enhances the accuracy of artificial intelligence judgment by collecting feedback from the manual review process.

[0034] The audit report and inventory module 32 are used to record and report the greenhouse gas emissions of the audited unit end 5. The greenhouse gas emissions of the audited unit end 5 are recorded in the inventory report and inventory. Among them, the inventory report is an overview file used to evaluate and record the greenhouse gas inventory results of the audited unit end 5. It is usually written by a professional inventory agency or an internal inventory team. The report covers key contents such as the inventory objectives, methods, scope, data collection process, emission calculation methods, and emission results of the audited unit end 5. The inventory is a list that records the sources of greenhouse gas emissions and related information of the audited unit end 5 within the scope of the inventory. It subdivides and classifies the emissions of the audited unit end 5, including emission source projects of different categories (such as energy use, transportation, manufacturing processes, etc.). The inventory report is like Figure 4 As shown, greenhouse gas emissions can be divided into direct and indirect greenhouse gas emissions.

[0035] Direct greenhouse gas emissions include: fuel combustion in fixed equipment, such as boilers, furnaces, incinerators, etc. (i.e., fixed source combustion); mobile combustion sources such as raw materials, products, waste and employee transportation under control (i.e., mobile source combustion); emission sources such as acetylene used in cutting, physical or chemical process emissions of CO2 from catalytic cracking in refining processes (i.e., industrial processes); intentional and unintentional emissions, such as leakage of equipment joints, seals, fillings, or fugitive emissions from refrigerants (i.e., fugitive emissions); land use change emission sources that may cause changes in carbon stocks, such as changes from forest land to agricultural land, or from cultivated land to non-cultivated land (i.e., land use related and forestry).

[0036] Examples of indirect greenhouse gas emissions include: production of input energy, electricity consumption, steam, heat, cooling, compressed air, gas, etc.; upstream transportation of goods (i.e. upstream transportation and cargo distribution), downstream transportation of goods (i.e. downstream transportation and cargo distribution), employee commuting, etc.; factories, equipment, etc. from products used by the organization (i.e. indirect greenhouse gas emissions from the use of products by the organization); and investments, equity debt, investment debt, etc. derived from the use of the organization's products (i.e. indirect greenhouse gas emissions related to the use of the organization's products).

[0037] The inventory list is as follows: Figure 5 As shown, a detailed description of the emissions of 5 different activities and processes at the audited unit end is provided, such as: the input electricity is 417.5225, accounting for 100%, the input energy is 0.0000, accounting for 0.00%; the total is 417.5225 (tCO2e). Help organizations better understand the sources of emissions, identify potential emission reduction opportunities, and formulate and implement subsequent emission reduction strategies. The various greenhouse gas emission items listed in the aforementioned inventory are presented in different document voucher image data, such as: purchase orders, electricity bills, gas invoices, commuting distances, etc., and larger equipment (such as: ice machines, air conditioners, water dispensers, dehumidifiers, etc.) take photos of the equipment nameplates and emission source nameplates as voucher image data (such as Figure 6 , Figure 7 The audit process of the present invention is to check the correctness of the items listed in the two documents, the inventory report and the inventory list.

[0038] The major emission source activity data sampling module 33 is used to determine the sampling quantity (ratio) and sampling allocation in each category, and sampling allocation under various evaluation models that cause data quality differences. It must have flexible adjustment capabilities, convenient settings and self-learning capabilities.

[0039] The OCR character recognition module 34 is used to perform optical character recognition on the image data of the documents and vouchers attached to each item listed in the inventory (such as: purchase orders and / or electricity bills and / or distances and / or... and other related information), and the nameplate photos on the emission sources to obtain relevant text and digital data, and compare them with the relevant audit data provided by the inventory audit database 36. It is also capable of providing the collaborative platform with the recognition conditions that are affected by blurring, stains, etc. due to long-term placement, and re-recognizes after discussion and strengthens artificial intelligence learning.

[0040] The interactive platform module 35 for sampling data verification is a collaborative platform for the above modules. Although the present invention emphasizes artificial intelligence auditing, it is impossible to complete the automated auditing part 100, and information disclosure is still required through the collaborative platform to provide auditors with opportunities to raise questions or make supplementary suggestions, and the audited unit end 5 to provide replies, explanations or supplementary materials, thereby simplifying the process of document exchanges between the two parties and reducing the work of on-site inspections by auditors at the audit unit end 3.

[0041] The inventory audit database 36 provides relevant audit required information, such as: 1. Carbon coefficient database provided by various countries or third-party manufacturers: Different countries provide different carbon coefficient definitions. For projects beyond the defined range, the carbon coefficient can be evaluated by a professional third party, or an estimated carbon coefficient can be obtained through self-definition and analogy.

[0042] 2. Database of basic information of each brand of equipment: Provides basic information marked on each brand and / or model of equipment, such as power consumption, product carbon footprint, etc.

[0043] Through the above combination, the audited unit terminal 5 provides the inspection report and the inspection list, as well as the image data of the documents and vouchers attached to each item listed in the inspection, and other materials to be verified. The audit unit terminal 3 verifies and audits the inspection report, the inspection list, and the image data of the documents and vouchers in a sampling ratio operation, and the optical character recognition (OCR) data and the referenced carbon coefficient data and other necessary data. If the verified data is correct, the certification operation will be carried out; if the data is incorrect or needs to be clarified, the inspection discovery report will be given to the audited unit terminal 5 for reply operation, and before the next stage of on-site verification, the inspection report and the inspection list will be re-made and given to the audit unit terminal 3. This can save a lot of manpower and time, simplify the operation process, speed up the on-site verification operation time, and can be used for 100% activity data and carbon coefficient audit operations.

[0044] See also Figure 8 and Fig. 9 , is the audit flow chart of the present invention. As shown in the figure, the audit process of the present invention at least includes the following steps: 1. Calculate the carbon inventory value A1, which is an artificial intelligence calculation of the audited unit terminal 5 or product carbon inventory value. The audited unit terminal 5 submits the inventory report and inventory list to the audit unit terminal 3. The audit ratio can be set by the audited unit terminal 5, but it must be at least 15% or a ratio that meets the audit specifications. The audit unit terminal 3 compares the correctness of the inventory report and inventory value. This step is performed by the accounting organization and product carbon emission value module 31 and the verification inventory report and inventory list module 32, and the preliminary verification results are sent to the interactive platform module 35 for sampling data verification.

[0045] 2. Sampling ratio operation A2: The major emission source activity data sampling module 33 performs sampling ratio operation on major emission sources and activity data, and pushes the data to the interactive platform module 35 for sampling data verification.

[0046] 3. Confirm the activity data A3. The activity data is confirmed by the OCR character recognition module 34, including: a. The company operates a systematic data character recognition verification and audit. After sampling, the audited unit terminal 5 is requested to provide a screenshot of the system to the interactive platform module 35 for sampling data verification, and conduct an OCR character recognition verification and audit of the document voucher image data. If the data is unreliable, the data will be marked and then discussed on the collaborative platform.

[0047] b. Verify and review the character recognition of paper data images. Verify and review the OCR character recognition of the image data of the document voucher. If the data is unreliable, mark the data and discuss it on the collaborative platform.

[0048] 4. The comparison software has a built-in carbon check coefficient A4, which is the data verified and reviewed by the built-in check audit database 36 and OCR character recognition, including: a. The audited unit uses the carbon coefficient at the end 5: there is a built-in inventory audit database 36 to compare the differences in numerical values. If the data is unreliable, the data will be marked and then discussed on the collaborative platform.

[0049] b. The audited entity terminal 5 uses carbon coefficient: there is no built-in inventory audit database 36, and the numerical difference cannot be compared. The audited entity terminal 5 is requested to provide a screenshot and standard of the carbon coefficient it cites, and then discuss on the collaboration platform.

[0050] 5. On-site verification A5. After the collaborative platform is in operation, a list file will be listed for the above-mentioned marked activity data or the unreliability of the inventory audit database 36, and on-site verification can be carried out when verifying the boundaries and emission sources.

[0051] 6. Issuance of certificate operation A6: If the verified data is correct, the issuance of certificate operation will be carried out. If the data is incorrect or needs to be clarified, the inspection and discovery report will be logged in the interactive platform 35 for sampling data verification and given to the audited unit terminal 5 for reply operation. Before the next stage of on-site verification, the inspection report and inspection list will be re-made and given to the audited unit terminal 3.

[0052] The present invention mentioned above uses OCR character recognition verification and auditing to save the audit unit end 3 from the need for personnel operation and the process of going back and forth to the audited unit end 5, thereby saving a lot of manpower and time and simplifying the operation process, and speeding up the on-site verification operation time, and can be used for 100% activity data and carbon coefficient audit operations, thereby improving the existing inventory operations that require a lot of time to prepare and confirm verification data.

[0053] The above embodiments are only for illustrating the preferred implementation of the present invention, but not for limiting the scope of the present invention. Any slight modification or change will not lose the essence of the present invention and will not deviate from the spirit of the present invention.

[0054] In summary, the present invention provides the audited unit with an inventory report and inventory list, as well as the image data of the documents and vouchers attached to each item listed in the inventory, and other data to be verified. The auditing unit performs optical character recognition (OCR) data and referenced carbon coefficient data and other necessary data verification and auditing on the inventory report, inventory list and image data of the documents and vouchers in a sampling ratio operation. The verification operation is directly performed on the audited unit that collects data using a digital platform, thereby saving a lot of manpower and time, simplifying the audit operation process, and accelerating the on-site verification operation time, and can provide 100% activity data and carbon coefficient audit operations.
