Description

Technical Field

[0001] The present disclosure relates to the technical field of carbon pollution emission accounting, and particularly to a method for accounting carbon pollution emissions of industrial enterprises. Background Art

[0002] An inventory of air pollutants and greenhouse gases (hereinafter referred to as carbon pollution) emissions is a prerequisite for identifying the sources of various air pollutants and greenhouse gas emissions and formulating reasonable policies for pollution reduction, carbon emission reduction, and air pollution prevention and control. Various carbon pollution emissions in the production process of industrial enterprises are the main sources of air pollutants and greenhouse gases. Accurately accounting for the carbon pollution emissions of industrial enterprises is very important for the accuracy of the emission inventory data. However, currently, the accounting of carbon pollution emissions of industrial enterprises is based on the production process data filled in by enterprises in the emission source statistical data. However, due to the low quality of the production process data filled in by some industrial enterprises, there are problems of missing calculation and overcalculation in the production links and processes, resulting in inaccurate corresponding carbon pollution emission data.

[0015] To more clearly illustrate the technical solutions in the embodiments of the present disclosure or the prior art, the following will briefly introduce the drawings required for use in the description of the embodiments or the prior art. Obviously, for those of ordinary skill in the art, other drawings can also be obtained based on these drawings without creative efforts, where: Figure 1 is a flowchart of the carbon pollution emission accounting method for industrial enterprises provided by the embodiment of the present disclosure; Figure 2 is a flowchart of the method for constructing a carbon pollution emission accounting system for a target enterprise in some embodiments; Figure 3 is a flowchart of the method for verifying the filled-in production activity level data in some embodiments; Figure 4 It is a flowchart of a method for verifying the reported production activity level data in some other embodiments; Figure 5 It is a flowchart of a method for verifying the reported production activity level data in still some other embodiments. Specific embodiments

[0016] Embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. Although some embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure can be implemented in various forms and should not be construed as limited to the embodiments set forth herein. On the contrary, these embodiments are provided to more thoroughly and completely understand the present disclosure. It should be understood that the drawings and embodiments of the present disclosure are only for exemplary purposes and are not used to limit the protection scope of the present disclosure.

[0017] The term "including" and its variations used herein are open-ended, that is, "including but not limited to". The term "based on" is "at least partially based on". The term "one embodiment" means "at least one embodiment"; the term "another embodiment" means "at least one additional embodiment"; the term "some embodiments" means "at least some embodiments". The relevant definitions of other terms will be given in the following description. In this document, relational terms such as "first" and "second" are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations.

[0018] Embodiments of the present disclosure provide a method for calculating the carbon and pollutant emissions of industrial enterprises to more accurately determine the carbon and pollutant emissions of a single industrial pollution discharge enterprise, and thus more precisely realize the construction of carbon and pollutant emission inventories at each level (such as geographical regions, provinces, municipalities divided into districts, and districts and counties).

[0019] It should be noted that the carbon and pollutant emission accounting in the embodiments of the present disclosure is a general term. In actual applications, it may be the accounting of greenhouse gases (i.e., "carbon") and atmospheric pollutants (i.e., "pollutants"), and specifically may be the accounting of specific greenhouse gases or specific atmospheric pollutant emissions. Considering that the emissions of atmospheric pollutants and greenhouse gases are "from the same origin", the solutions of the embodiments of the present disclosure can be used to simultaneously calculate the greenhouse gas and atmospheric pollutant emissions of industrial enterprises.

[0020] Figure 1 It is a flowchart of the method for calculating the carbon and pollutant emissions of industrial enterprises provided by the embodiments of the present disclosure. As Figure 1 shown, the method for calculating the carbon and pollutant emissions of industrial enterprises provided by the embodiments of the present disclosure includes S110 - S140.

[0021] S110: Mine the information of the emission source statistical data filled in by the target enterprise, and construct a carbon and pollution emission accounting system for the entire production process of the target enterprise.

[0022] The carbon and pollution emission accounting system described in the embodiments of the present disclosure is an accounting system refined to the process level. That is to say, the carbon and pollution emission accounting system provided by the embodiments of the present disclosure is obtained by subdividing and disassembling based on the production processes of the target enterprise, and is an accounting system that can reflect the carbon and pollution emission situation of the entire production process of the target enterprise. The goal of constructing a carbon and pollution emission accounting system for the target enterprise is to determine the combination of production and pollution discharge coefficients used when the target enterprise conducts carbon and pollution accounting. Intuitively, it is to determine the combination of production and pollution discharge coefficients used in each process of the target enterprise.

[0023] In some embodiments, the emission source statistical data includes multiple filling forms. For example, under the existing administrative requirements, the emission source statistical data filled in by industrial enterprises includes a series of forms such as Form 101, Form 106, and Form 110. There are duplicate filling items among the foregoing multiple filling forms. Although the data attributes of the duplicate filling items are the same, the data content filled in by the enterprise during the filling process is different (for example, the amount of data filled in is different).

[0024] Figure 2 It is a flowchart of the method for constructing a carbon and pollution emission accounting system for the target enterprise in some embodiments. As Figure 2 shown, in the case where the emission source statistical data may include duplicate filling items and there may also be missing filling content, mining the information of the emission source statistical data filled in by the target enterprise and constructing the corresponding carbon and pollution emission accounting system includes S111 - S112.

[0025] S111: Horizontally compare and mine the data in multiple filling forms filled in by the target enterprise to obtain the first system information, and compare and mine based on the first system information and the data in the production and pollution discharge coefficient library to obtain the second system information.

[0026] The first system information is the system information directly determined based on the emission source statistical data. For example, when an enterprise fills in a certain production product, then determining the information of this production product can be used as the first system information.

[0027] The second system information is the system information obtained by extension and cannot be directly determined from the emission source statistical data.

[0028] In specific implementation, data in multiple filling forms filled by the target enterprise are horizontally compared and mined to obtain the first system information, which is to traverse each data item in each filling form and identify the information relevant to determining the enterprise's carbon pollution emission accounting system. After obtaining the relevant information mentioned above, the relevant information is then compared and verified to determine the first system information therein.

[0029] For example, the information filled by the enterprise in the form may include products, raw materials, production processes, pollution control processes, etc. If the enterprise fills in the above information in the emission source statistical data, then it is highly probable that the above information is the information on the true production situation of the enterprise. Therefore, the above information can be used as the first system information.

[0030] In specific implementation, there may be missing data in the emission source statistical data filled by the target enterprise, specifically, it may be that the enterprise's products, raw materials, production processes, and pollution control processes are missing. The above-mentioned missing data causes the carbon pollution emission accounting system not to form an accounting system that covers the entire production process and realizes the accounting of the entire production process. In this case, it is necessary to use the existing information as much as possible to predict and restore the missing system information that cannot be directly obtained from the emission source statistical data due to the missing data, that is, to predict and restore the second system information mentioned above.

[0031] In the embodiments of the present disclosure, the second system information is obtained by comparing the first system information with the data in the production and pollution discharge coefficient library. Specifically, how to obtain the second system information by comparing the first system information with the data in the production and pollution discharge coefficient library will be elaborated later.

[0032] Considering that the direct factors affecting the enterprise's carbon pollution emissions include the products produced by the enterprise, the raw materials used by the enterprise, the production processes of the enterprise, the production processes adopted in the production processes, the production molds of the production processes, and the pollution control processes, and from the perspective of production, the previous factors among the above factors limit the optional range of the subsequent factors, the embodiments of the present disclosure construct a carbon pollution emission system including the above six levels, and the levels are from top to bottom. On this premise, in order to obtain the first system information and the second system information of each level, the above S111 may include the following S1111-S1112.

[0033] S1111: Horizontally compare and mine the data in multiple filling forms to obtain the first system information of each level respectively.

[0034] S1112: Refer to the production and pollution discharge coefficient library, and obtain the second system information of the current level based on at least part of the first system information of the current level, the first system information of the previous level, and the second system information.

[0035] Referring to the analysis in S1111 - S1112, in the embodiments of the present disclosure, the first system information and the second system information of the corresponding levels are determined level by level from the upper level to the lower level. Since determining the first system information in the corresponding level is to extract data from the filled - in form data, which is relatively simple and will not be elaborated here. Here, more analysis will be carried out on how to determine the second system information of each level.

[0036] For the product level in the foregoing levels, after obtaining the product information (i.e., the first system information) in the pollution source filling - in data, based on the association relationships between products, between products and raw materials, and between raw materials and products in the pollutant discharge coefficient library, the products not filled in by the enterprise can be identified, and the foregoing products are used as the second system information corresponding to the product level.

[0037] For the raw material level in the foregoing levels, after obtaining the raw material information of the pollution source filling - in data, based on the raw material information and the already identified product information, combined with the corresponding relationship between raw materials and products in the pollutant discharge coefficient library, it can be determined whether to supplement the raw material information, and the foregoing raw material information is used as the second system information corresponding to the raw material level.

[0038] For the production process in the foregoing data items, it may be a single - step production process or a continuous production process. When the target enterprise adopts a continuous production process, it may miss filling in some processes in the continuous production process. Therefore, it is necessary to focus on whether the target enterprise adopts a continuous production process and whether it misses reporting processes when adopting a continuous production process. Specifically, when determining the production process in the carbon pollution emission system, the following S01 - S08 may be included.

[0039] S01: Query the pollutant discharge coefficient library according to the products and raw materials in the first system information to identify whether the production process adopted by the target enterprise is a continuous production process; if so, execute S02; if not, execute S08.

[0040] S02: Determine the possible continuous production processes based on the pollutant discharge coefficient library.

[0041] A continuous production process refers to a process that requires at least two processes from raw materials to the production of a specific product. For example, for an iron and steel enterprise, from iron ore to steel, it needs to go through the stages of pellet sintering, blast furnace ironmaking, steelmaking (converter steelmaking or electric arc furnace steelmaking), refining, and rolling. After determining the products and raw materials, the pollutant discharge coefficient library can be queried through the products and raw materials to determine whether the production process adopted by the target enterprise is a continuous production process.

[0042] S03: Judge whether the production process filled in by the target enterprise conforms to a possible continuous production process; if so, execute S04; if not, execute S05.

[0043] S04: Take a potentially continuous production process as the production process adopted in the carbon pollution emission accounting system.

[0044] S05: Determine supplementary processes based on the typical processes in the potentially continuous production process and the production processes in the first system information, and take the reported processes and supplementary processes as the production processes in the carbon pollution emission accounting system.

[0045] When the target enterprise has reported the production process, and the reported production process is a continuous production process and the reported processes are complete, in most cases, the production process reported by the target enterprise is correct and in line with the actual situation. In this case, the production process reported by the enterprise (which is a potentially continuous production process) can be taken as the production process adopted in the carbon pollution emission accounting system.

[0046] If the process reported by the target enterprise does not match any of the potentially continuous production processes, it indicates that the production process reported by the target enterprise is an incomplete continuous production process (that is, there are production processes with missing reports). In this case, it is necessary to supplement the missing production processes.

[0047] Specifically, considering the economy of the production process, most enterprises in the same industry generally adopt the same production process for production. The aforementioned same production process is the typical process. When it is determined that some production processes are missing in the process reported by the target enterprise, the typical processes in all the potentially continuous production processes in its industry can be used as a reference, compared with the reported processes, to determine which processes are missing in the target enterprise, and the corresponding such processes can be used as supplementary processes. After determining the supplementary processes, the reported processes and supplementary processes can be combined in a reasonable process sequence as the production processes in the carbon pollution emission accounting system.

[0048] In some cases, when the target enterprise reports the production process, it may report the important processes in the continuous production process but forget to report the necessary general processes in the continuous production process. For example, for a manufacturing enterprise, it may forget to report the post-painting process of the product. The necessary general processes can also be used as the aforementioned supplementary processes, and the typical processes in the potentially continuous production process are used to determine such necessary general processes.

[0049] S06: Judge whether the data reported by the target enterprise is missing a single-step production process; if so, execute S07; if not, execute S08.

[0050] S07: Select a typical single-step production process as the production process in the carbon pollution emission accounting system.

[0051] S08: Take the reported production process as the production process in the carbon pollution emission accounting system.

[0052] S06 - S08 are the steps for determining the production processes in the carbon pollution emission accounting system when it is determined that the production process is a single - step production process. It mainly considers selecting a typical single - step production process as a supplementary process in the case of missing the selected production process in the filling. The specific operation is the same as the method for determining the supplementary process in the previous text, and no further analysis will be carried out here.

[0053] In some specific applications, although the target enterprise fills in all production processes according to the actual situation, it does not consider some general source items. For example, it may not consider the particulate matter emissions caused by injecting raw materials into the storage yard, the emissions of volatile organic compounds caused by storing volatile organic liquids in storage tanks and loading volatile organic liquids, and the emissions of volatile organic compounds, nitrogen oxides, and carbon oxides caused by torch combustion. In this case, it is also possible to determine whether to include general pollution source items based on the determined products, raw materials, and the determined production processes (including the filled - in processes and supplementary processes mentioned above). When it is determined that the target enterprise includes general pollution source items, the processes corresponding to the general pollution source items are also used as the production processes adopted in the carbon pollution emission accounting system.

[0054] In the embodiments of the present disclosure, when determining the production process, production scale, and pollution control process adopted by each production process, it is also necessary to consider the data supplementation problem when the target emission enterprise misses filling in the corresponding data items. In specific implementation, in the case where the production process, production scale, or pollution control process adopted by a certain production process is missing in the emission source statistical data, the process data corresponding to the typical situation under a certain production process can be used to supplement the corresponding missing data.

[0055] S112: Based on the first system information and the second system information, construct a carbon pollution emission accounting system for the entire production process of the target enterprise and refined to the process level.

[0056] In specific implementation, constructing a carbon pollution emission accounting system based on the first system information and the second system information is to construct the corresponding levels in the carbon pollution emission system based on the first system information and the second system information at each level in turn. After determining the system information of the upper level, then add the lower - level system information associated with the upper - level system information to the corresponding level, and associate the lower - level system information with the corresponding upper - level system information.

[0057] S120: Retrieve the production - pollution discharge coefficient library based on the carbon pollution emission accounting system, and determine the target production - pollution discharge coefficient combination corresponding to the carbon pollution emission accounting system.

[0058] In the embodiments of the present disclosure, the production and pollution discharge coefficient library at least includes various possible combinations of carbon pollution production and pollution discharge coefficients for the industries to which the target enterprises belong. The production and pollution discharge coefficient library is established based on the existing statistical coefficient system framework of emission sources, combined with the existing pollution source emission inventory, greenhouse gas emission inventory, etc., through data collation work such as comparison, mapping, and integration. The production and pollution discharge coefficient library is also a coefficient library refined to the enterprise process level.

[0059] In a specific application, in addition to the data included in the current production ranking coefficient guide, the production and pollution discharge coefficient library also adds the pollution production coefficients of indicators such as PM 10 , PM 2.5 , BC, OC, NH3, and CO2 by referring to literature data and emergency data of relevant regions.

[0060] In addition, in order to meet the requirements of refined accounting of carbon pollution emissions, compared with the existing production and pollution discharge coefficient library, the production and pollution discharge coefficient library in the embodiments of the present disclosure adds pollution control processes and refines the corresponding production and pollution discharge coefficients based on the pollution control processes.

[0061] Retrieving the production and pollution discharge coefficient library based on the carbon pollution emission accounting system is a hierarchical retrieval until the lowest level is determined, thereby determining the target production and pollution discharge coefficient combination. The aforementioned hierarchical retrieval sequentially uses products, raw materials, production processes, production technologies, production scales, and pollution control processes in the carbon pollution emission accounting system for corresponding level retrievals.

[0062] Specifically, first use the products in the aforementioned carbon pollution emission accounting system to find the corresponding products at the product level in the production and pollution discharge coefficient library, then retrieve the raw material level based on the raw materials in the carbon pollution emission accounting system to find the corresponding raw materials, and then find the corresponding production processes at the production process level associated with the raw materials based on the production processes in the carbon pollution emission accounting system, as well as find the corresponding production technologies at the lower-level technology level associated with the production processes based on the production technologies, and find the corresponding production scales at the lower level associated with the production scales based on the production technologies. Finally, find the corresponding pollution control processes at the lower-level pollution control processes associated with the production scales. After determining the lowest-level pollution control process, the production and pollution discharge coefficients are determined.

[0063] S130: Check and supplement the production activity level data filled in the emission source statistical data to obtain the checked production activity level data.

[0064] The production activity level data mentioned in the embodiments of the present disclosure can be the consumption of a certain raw material or the output of a certain product.

[0065] Check the production activity level data reported in the emission source statistical data, and the checked production activity level data is obtained by using various methods to identify the possible incorrect data in the reported production activity level data and correct the aforementioned possible incorrect data to obtain the possible correct production activity level data.

[0066] Figure 3 The flowchart of the method for checking the reported production activity level data in some embodiments is as follows. Figure 3 As shown, in some embodiments, the following S131 - S132 method can be used to obtain the checked production activity level data.

[0067] S131: Identify the target data with proportional relevance in the reported production activity level data and calculate the correlation coefficient of the target data.

[0068] S132: In the case where the correlation coefficient does not conform to the normal coefficient interval, identify the reasonable data and unreasonable data in the target data, estimate the alternative data corresponding to the unreasonable data based on the reasonable data and the corresponding normal correlation coefficient, and replace the unreasonable data with the alternative data as the checked production activity level data.

[0069] Here, for example, the production activity level data reported by a certain waste incineration power plant includes the emissions of sulfur dioxide, nitrogen oxides, and particulate pollutants of a certain unit. There is a certain correlation between the emissions of the aforementioned various pollutants, and the correlation coefficient should be within a certain range. However, the reported production activity level data of this enterprise are 20,000 tons, 20,000 tons, and 200,000,000 tons respectively. Using the aforementioned production activity level data for comparison, the correlation coefficients obtained by taking the particulate pollutant emissions as the divisor and the other pollutant emissions as the dividend are 0.0001 and 0.0001. Comparing the two calculated correlation coefficients with the data in the normal coefficient interval, it is obvious that the two correlation coefficients are unreasonable. In this case, through data verification and analysis, it can be clearly determined that "200,000,000 tons" in the three production activity level data is obviously unreasonable, that is, this data is unreasonable data, while the data levels of the other two production activity level data conform to the normal coefficient interval, and these two data are determined to be normal production activity level data.

[0070] Figure 4 The flowchart of the method for checking the reported production activity level data in some other embodiments is as follows. Figure 4 As shown, in some other embodiments, the following S133 - S134 can be used to obtain the checked production activity level data.

[0071] S133: Determine whether the difference between the production activity level data reported in different reporting items but for the same production process in the emission source statistical data is less than the set proportional threshold; if so, execute S134. S134: Use the maximum value among the production activity level data for the same production process as the corrected production activity level data.

[0072] When filling in the emission source statistical data, the production activity level data for some production processes may be filled in different reporting items. For example, some production activity level data are filled in the data items of the basic information table and the corresponding production activity data items at the same time. In this case, the problem that the data filled in different data items is not consistent may occur, and it is not easy to determine which data is the correct data. In the embodiments of the present disclosure, considering that the various data filled in the emission source statistical data are the data actively filled in by the enterprise, although there are differences, the data should be credible to a certain extent, and the target enterprise should be responsible for its filled data. Based on this, if it is determined that the production activity level data reported in different reporting items but for the same production process in the emission source statistical data is less than the set proportional threshold, the maximum value is artificially used as the credible production activity level data, and correspondingly, it is also used as the verified production activity level data.

[0073] It should be noted here that if the difference between the production activity level data for the same production process is greater than the set proportional threshold, it indicates that the corresponding data may not be credible, and other methods are needed to verify and correct the data.

[0074] It should be noted here that in some cases, some production activity level data for a production process are the production activity level data for each production line in this production process. In this case, it is necessary to add up the production activity level data of each production line to obtain the production activity level data for this production process, and then this production activity level data can be compared with the production activity level data filled in other data items. And, if the difference between the sum value of the production activity level data of each production line and the other corresponding data reporting item is greater than the set proportional threshold, and the other data reporting item is also greater than the aforementioned sum value, the value of the other larger data reporting item will also be split according to the ratio of the production activity level of each production line to the sum value to obtain the corrected production activity level data of each production line.

[0075] Figure 5 It is a flowchart of the method for verifying the filled production activity level data in some embodiments. As Figure 5 shown, in some embodiments of the present disclosure, the following S135 - S139 can be used to determine the verified production activity level data.

[0076] S135: Obtain the production activity level data of enterprises similar to the target enterprise in scale.

[0077] S136: Conduct statistical analysis based on the production activity level data of enterprises similar in scale to determine the credible production activity level interval.

[0078] Obtaining the production activity level data of enterprises similar to the target enterprise in scale ensures the rationality of the subsequent determined credible production activity level interval. In specific implementation, to further ensure the reliability of the credible production activity level interval, when obtaining the production activity level data of enterprises similar in scale, the production activity level data of only those enterprises similar in scale that adopt the same carbon emission accounting system can also be obtained.

[0079] In specific implementation, after obtaining the production activity level data of enterprises similar in scale, the production activity level data can be sorted to obtain a sorted sequence, and then the first quartile and the third quartile in the sorted sequence can be determined based on the interquartile range method, and the credible production activity level interval can be determined based on the difference between the first quartile and the third quartile and two data.

[0080] In a specific implementation, after determining the aforementioned first quartile and third quartile (assuming the first sorted sequence is in ascending order from small to large here), the interquartile range is calculated using the first quartile and the third quartile, and then an extended value is calculated using the interquartile range and a preset value (in practical applications, the preset value may be greater than 1 or less than 1). Subsequently, the lower limit of the credible production activity level interval can be obtained by subtracting the extended value from the first quartile, and the upper limit of the credible production activity level interval can be obtained by adding the extended value to the third quartile. After obtaining the lower limit and the upper limit of the credible production activity level interval, the credible production activity level interval can be obtained.

[0081] S137: Determine whether the production activity level data filled in by the target enterprise falls within the credible production activity level interval; if so, execute S138; if not, execute S139.

[0082] S138: Take the filled production activity level data as the verified production activity data.

[0083] S139: Correct the filled production activity level data based on relevant data to obtain the verified production activity level data.

[0084] If the production activity level data filled in by the target enterprise does not fall outside the credible production activity level interval, the probability that the filled production activity level data is incorrect data is relatively high. At this time, the filled production activity level data can be corrected based on relevant data to obtain the verified production activity level data.

[0085] In specific implementation, the reported production activity level data can be corrected based on the product output, total industrial output value of the target enterprise, or the usage amount of the target raw material, so as to obtain the verified production activity level data. Specifically, the production activity level data per unit product output, production activity level data per unit output value, and production activity level data corresponding to per unit raw material usage amount of the whole industry can be calculated based on the product output, total industrial output value, or the usage amount of the target raw material corresponding to the data within the credible production activity data range. Then, by dividing the product output, total industrial output value, or the usage amount of the target raw material of the target enterprise by the corresponding production activity level data, the verified production activity level data can be obtained.

[0086] In some cases, when the production activity level data of a certain production process is missing, the production activity level data of the missing process can also be estimated based on the production activity level data of the upstream process and the downstream process.

[0087] S140: Calculate based on the verified production activity level data and the corresponding pollutant discharge coefficients in the target pollutant discharge coefficient combination to obtain the carbon and pollutant emissions of the target enterprise in the corresponding production process.

[0088] The pollutant discharge coefficients corresponding to the target enterprise are determined by using S110 - S120 described above, and the production activity level data corresponding to the target enterprise is determined by using S140 described above. Accordingly, by calculating based on the production activity level data of a specific process and the corresponding pollutant discharge coefficients in the target pollutant discharge coefficient combination, the carbon and pollutant emissions of the target enterprise in the corresponding production process can be calculated.

[0089] As analyzed above, in the embodiments of the present disclosure: (1) various possible carbon and pollutant production and discharge coefficient combinations refined to the process level for the industry to which the target enterprise belongs are constructed; (2) information mining is performed on the reported emission source statistical data of the target enterprise, a carbon and pollutant emission accounting system refined to the process level is constructed for the target enterprise, and the target pollutant discharge coefficient combination is determined based on the carbon and pollutant emission accounting system; (3) the reported production activity level data in the emission source statistical data is verified to determine the credibility of the production activity level data as much as possible; after obtaining the aforementioned target pollutant discharge coefficient combination and the verified production activity level data, the carbon and pollutant emissions of the target enterprise in the corresponding production process are calculated. That is to say, the solution of the embodiments of the present disclosure can achieve relatively accurate accounting of carbon and pollutant emissions for each production process of the target enterprise.

[0090] On the premise of achieving relatively accurate accounting of carbon and pollutant emissions for each production process of the target enterprise, the carbon and pollutant emissions of each process are accumulated, and relatively accurate carbon and pollutant emissions at the target enterprise level can be obtained. Accordingly, relatively accurate carbon and pollutant emissions under each statistical caliber can be obtained based on the relatively accurate carbon and pollutant emissions at the enterprise level.

Various modifications to these embodiments will be obvious to those skilled in the art. The general principles defined herein can be implemented in other embodiments without departing from the spirit or scope of the present disclosure. Therefore, the present disclosure will not be limited to these embodiments described herein, but rather will be accorded the widest scope consistent with the principles and novel features disclosed herein.
