Detailed Implementation

[0017] The embodiments of this application are described in detail below. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this application, and should not be construed as limiting this application.

[0018] CCUS (Carbon Capture, Utilization and Storage, also known as carbon capture and utilization) refers to the process of capturing and separating carbon dioxide (CO2) from industrial processes, energy use, or the atmosphere, transporting it via pipelines, ships, etc., and using it as a raw material for products or services, or injecting it into geological formations for permanent storage. CCUS technology comprises four stages: carbon capture, carbon transportation, carbon utilization, and carbon sequestration. Conducting quantitative, accounting, and verification studies on the actual emission reductions of CCUS technology is fundamental to evaluating its emission reduction effectiveness.

[0019] CCUS technology is an important technological approach for the cement industry to achieve carbon emission reduction.

[0020] Conducting quantitative assessments of product carbon footprints helps promote further energy conservation and carbon reduction for enterprises. There are three main methods for quantitative assessment of product carbon footprints: one is the "bottom-up" calculation method represented by LCA (Life Cycle Analysis); the second is the "top-down" calculation method represented by IOA (Input-Output Analysis); and the third is the hybrid life cycle assessment (Hybrid LCA) derived from the combination of the two methods.

[0021] There is currently no unified standard methodology for the quantitative evaluation of the carbon footprint of cement products. In recent years, domestic and international literature has also studied the carbon footprint of cement products. While the evaluation methods are generally consistent, problems remain, such as unclear accounting boundaries, incomplete accounting steps, and lack of specific accounting methods. The application of CCUS technology in the cement industry started relatively late, and most existing literature does not address the quantitative evaluation of the impact of carbon capture and utilization technology upgrades on the reduction of the carbon footprint of cement products. Therefore, it is necessary to construct relevant quantitative evaluation methods to scientifically quantify the impact of carbon capture and utilization technology upgrades on the carbon footprint of cement products.

[0022] To address the aforementioned issues, this application provides a data processing method for the carbon footprint of cement products. This method can obtain the greenhouse gas emissions of two cement products—one without carbon capture and utilization technology and the other with it—to generate a first dataset and a second dataset. By considering both datasets, an impact index of carbon capture and utilization technology on the carbon footprint of cement products can be obtained. This method can scientifically and quantitatively evaluate the impact of carbon capture and utilization technology upgrades on the carbon footprint of cement products, thereby improving the accuracy of the assessment of the impact of carbon capture and utilization technology on the carbon footprint of cement products.

[0023] The following description, with reference to the accompanying drawings, outlines a data processing method, apparatus, electronic device, and storage medium for the carbon footprint of cement products according to embodiments of this application.

[0024] Figure 1 This is a flowchart illustrating a data processing method for the carbon footprint of cement products provided in an embodiment of this application.

[0025] like Figure 1 As shown, the method includes the following steps: S101, for the first cement product that does not adopt carbon capture and utilization technology, the greenhouse gas emissions of the raw material acquisition, production and transportation process of the first cement product, as well as the greenhouse gas emissions of the first cement product production process, are added to the first dataset. The greenhouse gas emissions of the first cement product production process include the greenhouse gas emissions in the flue gas at the tail end of the cement kiln corresponding to the first cement product.

[0026] S102, for the second cement product using carbon capture and utilization technology, the greenhouse gas emissions from the raw material acquisition, production and transportation processes of the second cement product, as well as the greenhouse gas emissions from the production and carbon capture and utilization processes of the second cement product, are added to the second dataset. The greenhouse gas emissions from the production process of the second cement product include the greenhouse gas emissions from the kiln tail gas corresponding to the second cement product.

[0027] It should be noted that the first cement product refers to cement products that do not use carbon capture and utilization technology, while the second cement product refers to cement products that use carbon capture and utilization technology. The categories of the first cement product and the second cement product may be the same or different, and no further restrictions are imposed here.

[0028] The first dataset includes the greenhouse gas emissions corresponding to the first cement product, and the second dataset includes the greenhouse gas emissions corresponding to the second cement product. The greenhouse gas emissions can be obtained using any relevant method; no further restrictions are imposed here. No further restrictions are imposed on the raw materials for each type of cement product.

[0029] Optionally, the raw materials for the first cement product include the raw materials required for the production process of the first cement product, and the raw materials for the second cement product include the raw materials required for the production of the second cement product and the carbon capture and utilization process.

[0030] Optionally, the greenhouse gas emissions from the production process of either the first cement product or the second cement product can be obtained. This includes calculating the greenhouse gas emissions from the combustion of fossil fuels, net purchased electricity consumption, net purchased heat consumption, and greenhouse gas emissions from the flue gas at the end of the cement kiln during the production process of either cement product. This allows for a more accurate assessment of the greenhouse gas emissions from the cement product production process by comprehensively considering the greenhouse gas emissions from the combustion of fossil fuels, net purchased electricity consumption, net purchased heat consumption, and the flue gas at the end of the cement kiln.

[0031] In some examples, the greenhouse gas emissions of any cement product production process are obtained based on the greenhouse gas emissions from fossil fuel combustion, net purchased electricity consumption, net purchased heat consumption, and greenhouse gas emissions from cement kiln tail gas. This includes obtaining the sum of the greenhouse gas emissions from fossil fuel combustion, net purchased electricity consumption, net purchased heat consumption, and greenhouse gas emissions from cement kiln tail gas during the production of any cement product, which is taken as the greenhouse gas emissions of any cement product production process.

[0032] For example, the process of obtaining greenhouse gas emissions during the production of any cement product is as follows:

[0033] in, The greenhouse gas emissions during the production process of any cement product. The greenhouse gas emissions generated by the combustion of fossil fuels during the production of any cement product. The greenhouse gas emissions generated by net purchased electricity consumption during the production of any cement product. For any cement product, the greenhouse gas emissions generated by the net purchase of heat during the production process are considered. This represents the greenhouse gas emissions from the flue gas at the tail end of a cement kiln for any given cement product.

[0034] In some examples, the greenhouse gas emissions of any cement product production process are obtained based on the greenhouse gas emissions from fossil fuel combustion, net purchased electricity consumption, net purchased heat consumption, and greenhouse gas emissions from cement kiln tail gas. This includes a weighted sum of the greenhouse gas emissions from fossil fuel combustion, net purchased electricity consumption, net purchased heat consumption, and cement kiln tail gas during the production of any cement product. It is understood that the weights for these different categories of greenhouse gas emissions may differ.

[0035] Optionally, the greenhouse gas emissions in the flue gas from the kiln tail of the cement kiln corresponding to either the first cement product or the second cement product can be obtained, including obtaining the carbon dioxide emissions generated at the kiln tail of the cement kiln corresponding to either cement product, as the greenhouse gas emissions in the flue gas from the kiln tail of the cement kiln corresponding to either cement product.

[0036] For example, the process for obtaining the greenhouse gas emissions from the flue gas at the tail end of a cement kiln for any type of cement product is as follows:

[0037] in, This represents the carbon dioxide emissions generated at the kiln tail of any cement product.

[0038] Optionally, the greenhouse gas emissions of the carbon capture and utilization process of the second cement product are obtained, including the greenhouse gas emissions generated by the net purchased electricity consumption during the carbon capture and utilization process of the second cement product, as the greenhouse gas emissions of the carbon capture and utilization process of the second cement product.

[0039] For example, the process for obtaining greenhouse gas emissions from the carbon capture and utilization process of the second cement product is as follows:

[0040] in, Greenhouse gas emissions from the carbon capture and utilization process of the second cement product; The greenhouse gas emissions generated from net purchased electricity consumption during the carbon capture and utilization process of the second cement product; For the carbon capture and utilization process of the second cement product, the unit process i Greenhouse gas emissions from electricity consumption n The number of unit processes; For the carbon capture and utilization process of the second cement product, the unit process i The electricity consumption is expressed in MW·h (megawatt-hours), excluding the company's own photovoltaic and wind power generation. For the carbon capture and utilization process of the second cement product, the unit process i Electricity emission factor, in units of (tons of CO2 equivalent per megawatt-hour). Electricity consumption can be obtained by checking electricity metering devices or electricity purchase records. The electricity emission factor should be a reasonable total emission factor with low uncertainty, preferably obtained from the carbon footprint databases published by relevant departments.

[0041] It should be noted that the units for the above-mentioned greenhouse gas emissions are not strictly limited; for example, they can be tCO2e (tons of carbon dioxide equivalent). The calculation methods for some of the above-mentioned greenhouse gas emissions can be found in the following examples, and will not be repeated here.

[0042] S103, based on the first and second datasets, obtain the impact index of carbon capture and utilization technology on the carbon footprint of cement products.

[0043] It should be noted that no restrictions are placed on the indicators of the impact of carbon capture and utilization technology on the carbon footprint of cement products, such as carbon emission reduction and carbon emission reduction rate (also called reduction rate).

[0044] Optionally, based on the first and second datasets, an impact index of carbon capture and utilization technology on the carbon footprint of cement products can be obtained. This includes inputting the first and second datasets into the target model, and having the target model output the impact index of carbon capture and utilization technology on the carbon footprint of cement products. It should be noted that the target model is not subject to many restrictions, and may include mechanistic models, data-driven models, etc.

[0045] Optionally, after obtaining the impact indicators of carbon capture and utilization technology on the carbon footprint of cement products, the process also includes optimizing the carbon capture and utilization technology in response to the failure of the impact indicators to meet set conditions. For example, the carbon capture and utilization technology can be optimized in response to the carbon emission reduction being less than a first set value, and / or, in response to the carbon emission reduction rate being less than a second set value. Therefore, optimizing the carbon capture and utilization technology when the impact indicators fail to meet set conditions helps improve the carbon emission reduction effect of the carbon capture and utilization technology, and can further save energy and reduce carbon emissions.

[0046] In summary, according to the data processing method for the carbon footprint of cement products in this application embodiment, for a first cement product that does not adopt carbon capture and utilization technology, the greenhouse gas emissions from the raw material acquisition, production, and transportation processes of the first cement product, as well as the greenhouse gas emissions from the production process of the first cement product, are added to a first dataset. For a second cement product that adopts carbon capture and utilization technology, the greenhouse gas emissions from the raw material acquisition, production, and transportation processes of the second cement product, as well as the greenhouse gas emissions from the production and carbon capture and utilization processes of the second cement product, are added to a second dataset. The greenhouse gas emissions from the production process of any cement product include the greenhouse gas emissions in the flue gas from the kiln tail gas corresponding to any cement product. Based on the first and second datasets, an impact index of carbon capture and utilization technology on the carbon footprint of cement products is obtained. Therefore, the greenhouse gas emissions of two cement products, one without carbon capture and utilization technology and the other with it, can be obtained to generate a first dataset and a second dataset. By taking into account the first dataset and the second dataset, an impact index of carbon capture and utilization technology on the carbon footprint of cement products can be obtained. This allows for a scientific and quantitative evaluation of the impact of carbon capture and utilization technology on the carbon footprint of cement products, thus improving the accuracy of the assessment of the impact of carbon capture and utilization technology on the carbon footprint of cement products.

[0047] This application provides another method for processing the carbon footprint of cement products.

[0048] like Figure 2 As shown, the method may include the following steps: S201, for the first cement product that does not adopt carbon capture and utilization technology, add the greenhouse gas emissions of the raw material acquisition, production and transportation process of the first cement product, as well as the greenhouse gas emissions of the first cement product production process, to the first dataset. The greenhouse gas emissions of the first cement product production process include the greenhouse gas emissions in the flue gas from the kiln tail gas of the cement kiln corresponding to the first cement product.

[0049] S202, for the second cement product using carbon capture and utilization technology, the greenhouse gas emissions from the raw material acquisition, production and transportation processes of the second cement product, as well as the greenhouse gas emissions from the production and carbon capture processes of the second cement product, are added to the second dataset. The greenhouse gas emissions from the production process of the second cement product include the greenhouse gas emissions from the kiln tail gas of the cement kiln corresponding to the second cement product.

[0050] For details regarding steps S201-S202, please refer to the above embodiments, which will not be repeated here.

[0051] S203, based on the greenhouse gas emissions from the raw material acquisition, production, and transportation processes of the first cement product, as well as the greenhouse gas emissions from the production process of the first cement product, the first carbon footprint is obtained.

[0052] It should be noted that the first carbon footprint refers to the carbon footprint of the first cement product.

[0053] Optionally, the first carbon footprint is obtained based on the greenhouse gas emissions from the raw material acquisition, production, and transportation processes of the first cement product, as well as the greenhouse gas emissions from the production process of the first cement product. This first carbon footprint includes the sum of the greenhouse gas emissions from the raw material acquisition, production, and transportation processes of the first cement product and the greenhouse gas emissions from the production process of the first cement product.

[0054] For example, the process of obtaining the first carbon footprint is as follows:

[0055] in, For the first carbon footprint, The greenhouse gas emissions from the acquisition of raw materials and the production process of the first cement product. Greenhouse gas emissions from the transportation of raw materials for the first cement product. This refers to the greenhouse gas emissions from the first cement product production process.

[0056] Optionally, the first carbon footprint is obtained based on the greenhouse gas emissions from the raw material acquisition, production, and transportation processes of the first cement product, as well as the greenhouse gas emissions from the production process of the first cement product. This includes a weighted summation of the greenhouse gas emissions from the raw material acquisition, production, and transportation processes of the first cement product, as well as the greenhouse gas emissions from the production process of the first cement product.

[0057] S204, based on the greenhouse gas emissions from the raw material acquisition, production, and transportation processes of the second cement product, as well as the greenhouse gas emissions from the production and carbon capture and utilization processes of the second cement product, the second carbon footprint is obtained.

[0058] It should be noted that the second carbon footprint refers to the carbon footprint of the second cement product.

[0059] Optionally, a second carbon footprint is obtained based on the greenhouse gas emissions from the raw material acquisition, production, and transportation processes of the second cement product, as well as the greenhouse gas emissions from the production and carbon capture and utilization processes of the second cement product. The second carbon footprint includes the sum of the greenhouse gas emissions from the raw material acquisition, production, and transportation processes of the second cement product, as well as the greenhouse gas emissions from the production and carbon capture and utilization processes of the second cement product.

[0060] For example, the process of obtaining the second carbon footprint is as follows:

[0061] in, For the second carbon footprint, The greenhouse gas emissions from the acquisition of raw materials and the production process of the second cement product. Greenhouse gas emissions from the transportation of raw materials for the second cement product. This refers to the greenhouse gas emissions from the second cement product production process.

[0062] Optionally, a second carbon footprint is obtained based on the greenhouse gas emissions from the raw material acquisition, production, and transportation processes of the second cement product, as well as the greenhouse gas emissions from the production and carbon capture and utilization processes of the second cement product. This includes a weighted summation of the greenhouse gas emissions from the raw material acquisition, production, and transportation processes of the second cement product, as well as the greenhouse gas emissions from the production and carbon capture and utilization processes of the second cement product.

[0063] S205, based on the first and second carbon footprints, obtains the total impact index of carbon capture and utilization technology on the carbon footprint of cement products.

[0064] It should be noted that the total impact index of carbon capture and utilization technology on the carbon footprint of cement products, based on the first and second carbon footprints, can be obtained by using any of the calculation methods of the impact index in the relevant technologies, without further restrictions here.

[0065] Optionally, based on the first and second carbon footprints, a total impact index of carbon capture and utilization technology on the carbon footprint of cement products is obtained. This includes obtaining the deviation between the first and second carbon footprints as the first impact index of carbon capture and utilization technology on the carbon footprint of cement products, obtaining the ratio of the first impact index to the first carbon footprint as the second impact index of carbon capture and utilization technology on the carbon footprint of cement products, and using at least one of the first and second impact indices as the total impact index. It can be understood that the first impact index represents the total carbon emission reduction of carbon capture and utilization technology on the carbon footprint of cement products, and the second impact index represents the total carbon emission reduction rate of carbon capture and utilization technology on the carbon footprint of cement products.

[0066] For example, the process of obtaining the total impact indicator is as follows:

[0067]

[0068] in, As the primary indicator of influence, It is the second most influential indicator.

[0069] In summary, the data processing method for the carbon footprint of cement products according to the embodiments of this application can comprehensively consider the greenhouse gas emissions during the raw material acquisition, production, and transportation processes of the first cement product, as well as the greenhouse gas emissions during the production process of the first cement product, to obtain the first carbon footprint. Similarly, it can comprehensively consider the greenhouse gas emissions during the raw material acquisition, production, and transportation processes of the second cement product, as well as the greenhouse gas emissions during the production and carbon capture and utilization processes of the second cement product, to obtain the second carbon footprint. This improves the accuracy of the carbon footprint of cement products. Furthermore, by considering both the first and second carbon footprints, a total impact index of carbon capture and utilization technology on the carbon footprint of cement products can be obtained. This allows for a scientific and quantitative evaluation of the total impact of carbon capture and utilization technology upgrades on the carbon footprint of cement products, improving the accuracy of the assessment of the total impact of carbon capture and utilization technology on the carbon footprint of cement products.

[0070] This application provides another method for processing the carbon footprint of cement products.

[0071] like Figure 3 As shown, the method may include the following steps: S301, for the first cement product that does not adopt carbon capture and utilization technology, the greenhouse gas emissions of the raw material acquisition, production and transportation process of the first cement product, as well as the greenhouse gas emissions of the first cement product production process, are added to the first dataset. The greenhouse gas emissions of the first cement product production process include the greenhouse gas emissions in the flue gas from the kiln tail gas of the cement kiln corresponding to the first cement product.

[0072] S302, for the second cement product using carbon capture and utilization technology, the greenhouse gas emissions from the raw material acquisition, production and transportation processes of the second cement product, as well as the greenhouse gas emissions from the production and carbon capture and utilization processes of the second cement product, are added to the second dataset. The greenhouse gas emissions from the production process of the second cement product include the greenhouse gas emissions from the kiln tail gas corresponding to the second cement product.

[0073] For details regarding steps S301-S302, please refer to the above embodiments, which will not be repeated here.

[0074] S303, retrieve the first field of each of the multiple first data in the first dataset.

[0075] S304, retrieve the second field of each of the multiple second data in the second dataset.

[0076] It should be noted that the first data refers to the greenhouse gas emissions corresponding to the first cement product, including the greenhouse gas emissions during the acquisition, production, and transportation of the raw materials for the first cement product, as well as the greenhouse gas emissions during the production process of the first cement product.

[0077] The second data refers to the greenhouse gas emissions corresponding to the second cement product, including greenhouse gas emissions from the raw material acquisition, production, and transportation processes of the second cement product, as well as greenhouse gas emissions from the production and carbon capture and utilization processes of the second cement product.

[0078] Different first data may correspond to different first fields, and different second data may correspond to different second fields.

[0079] For example, the first dataset A includes { The second dataset B includes { }

[0080] , Each field contains information on the sourcing of raw materials for cement products and greenhouse gas emissions during the production process. , Each field represents greenhouse gas emissions during the transportation of raw materials for cement products. , Each field represents greenhouse gas emissions from the cement production process.

[0081] S305, if the first field of the first data is consistent with the second field of the second data, then based on the first data and the second data, obtain the sub-impact index of carbon capture and utilization technology on the carbon footprint of cement products.

[0082] For example, continuing with the first dataset A and the second dataset B, we can base it on... and We obtained sub-impact index 1 for carbon capture and utilization technology on the carbon footprint of cement products. It can be understood that sub-impact index 1 represents the impact of carbon capture and utilization technology on the acquisition of raw materials and greenhouse gas emissions during the production process of cement products.

[0083] Based on and Sub-indicator 2 was obtained regarding the impact of carbon capture and utilization technology on the carbon footprint of cement products. It can be understood that sub-indicator 2 represents the impact of carbon capture and utilization technology on greenhouse gas emissions during the transportation of raw materials for cement products.

[0084] Based on and Sub-indicator 3 was obtained to determine the impact of carbon capture and utilization technology on the carbon footprint of cement products. It can be understood that sub-indicator 3 represents the impact of carbon capture and utilization technology on greenhouse gas emissions during the cement production process.

[0085] It should be noted that the sub-impact indicators of carbon capture and utilization technology on the carbon footprint of cement products, based on the first and second data, can be obtained by using the calculation method of any impact indicator in the relevant technologies, without further restrictions here.

[0086] Optionally, based on the first and second data, sub-impact indicators of carbon capture and utilization technology on the carbon footprint of cement products are obtained. This includes obtaining the deviation between the first and second data as a third impact indicator, obtaining the ratio of the third impact indicator to the first data as a fourth impact indicator, and using at least one of the third and fourth impact indicators as a sub-impact indicator. It can be understood that the third impact indicator represents the sub-carbon emission reduction amount of carbon capture and utilization technology on the carbon footprint of cement products, and the second impact indicator represents the sub-carbon emission reduction rate of carbon capture and utilization technology on the carbon footprint of cement products.

[0087] For example, taking sub-impact indicator 1 as an example, the process of obtaining sub-impact indicator 1 is as follows:

[0088]

[0089] in, As the third influencing indicator, It is the fourth influencing indicator. To reduce carbon emissions from raw material acquisition and production processes in cement products through carbon capture and utilization technologies. This refers to the carbon emission reduction rate of cement products in terms of raw material acquisition and production processes through carbon capture and utilization technology.

[0090] It should be noted that the process of obtaining sub-influence indicators 2 and 3 can be referred to the process of obtaining sub-influence indicator 1, which will not be repeated here.

[0091] In summary, according to the data processing method for the carbon footprint of cement products in this application embodiment, the first fields of each of multiple first data in the first dataset are obtained, and the second fields of each of multiple second data in the second dataset are obtained. When the first fields of the first data and the second fields of the second data are consistent, a sub-impact index of carbon capture and utilization technology on the carbon footprint of cement products is obtained based on the first data and the second data. Therefore, the sub-impact of carbon capture and utilization technology on the carbon footprint of cement products can be scientifically and quantitatively evaluated, improving the accuracy of the assessment of the sub-impact of carbon capture and utilization technology on the carbon footprint of cement products.

[0092] For ease of understanding, an exemplary embodiment is provided: The first step is to define the boundaries of the carbon footprint quantification and evaluation system.

[0093] like Figure 4 As shown, the boundary of the first cement product carbon footprint quantification evaluation system includes raw material mining, production, and transportation; energy mining, production, and transportation; auxiliary material mining, production, and transportation; cement product production; and pollutant emissions. It is understood that the cement production process can simultaneously generate cement products and pollutants, including cement kiln tail gas.

[0094] like Figure 5 As shown, the boundary of the carbon footprint quantification evaluation system for the second cement product, i.e., the boundary of the carbon footprint quantification evaluation system for cement products after carbon capture and utilization technology transformation, includes raw material mining, production, and transportation; energy mining, production, and transportation; auxiliary material mining, production, and transportation; cement product production; carbon capture and utilization of cement kiln tail gas; and other pollutant emissions. It is understood that the cement production process can simultaneously generate cement products, cement kiln tail gas, and other pollutants. These other pollutants refer to pollutants other than those in the cement kiln tail gas. The carbon capture and utilization process of cement kiln tail gas can generate high-purity CO2 products.

[0095] The second step is to collect data.

[0096] The data includes activity level data and greenhouse gas emission factors.

[0097] Activity level data includes primary activity level data and secondary activity level data. Primary activity level data should preferably be obtained from direct measurement, followed by secondary data derived from the primary data. If neither of these is available, substitute data from similar unit processes can be used. Statistical data, design data, or estimated data can be used during the usage phase.

[0098] Data collection and data quality assessment follow these steps: a) Develop a data management plan and establish a database, and complete the data collection and evaluation process; b) Refer to Figure 4 , Figure 5 System boundary diagrams are used to identify the data that is needed, and process reviews are conducted to facilitate centralized data collection. c) For processes under direct control, collect raw data; d) For other processes, collect primary or secondary data and assess the data quality of direct emissions data, energy or material use data, and emission factors, etc. e) To improve data quality, analyze and identify data gaps, and collect higher quality data.

[0099] To construct a quantitative evaluation method for the impact of carbon capture and utilization technology upgrades on the reduction of the carbon footprint of cement products, the collected data items are divided into two categories according to their paths: one is data related to cement product production, and the other is data related to carbon capture and utilization.

[0100] Data related to cement product production mainly includes: a) The types and quantities of energy consumed in the process of obtaining raw and auxiliary materials related to cement production from natural resources; b) The types and quantities of energy consumed in the production process of the above-mentioned raw and auxiliary materials; c) The types and quantities of energy consumed during the transportation of the aforementioned raw and auxiliary materials; d) Types and quantities of energy consumed during the cement production process; e) The pollutant emissions generated during processes a to d above, including carbon dioxide produced by the decomposition of calcium carbonate and the disposal and utilization of solid waste.

[0101] Data related to carbon capture and utilization mainly include: a) The types and quantities of energy consumed in the process of obtaining raw and auxiliary materials related to carbon capture and utilization from natural resources (such as the absorbent method used in carbon capture and utilization technology, where raw and auxiliary materials include absorbent). b) The types and quantities of energy consumed in the production process of the above-mentioned raw and auxiliary materials; c) The types and quantities of energy consumed during the transportation of the aforementioned raw and auxiliary materials; d) Types and quantities of energy consumed during carbon capture and utilization; e) The pollutant emissions generated during processes a to d above.

[0102] Greenhouse gas emission factors should be prioritized based on measured or calculated values ​​obtained directly by enterprises or through energy balance, material balance, or other methods. Secondly, emission factors provided by relevant guidelines, documents, and databases should be used.

[0103] The third step is to conduct quantitative analysis.

[0104] After data collection is complete, each unit process and functional unit in the product system should be quantified. Quantification should use a unified functional unit as the common basis for the material and energy flows in all unit processes of the product system, obtaining all input and output data in the system, and summarizing them to obtain the final quantified result of the product's carbon footprint, expressed in carbon dioxide equivalent (CO2e). During this process, any unreasonable data should be replaced.

[0105] Quantification is carried out in the following steps: a) Multiply the activity level data by the activity's emission factor to convert the primary activity level data and secondary data into GHG (Greenhouse Gas Emissions), which is recorded as GHG emissions per functional unit of the product.

[0106] b) Multiply the specific GHG emission value by the corresponding GWP (Global Warming Potential) value to convert the GHG emission data into carbon dioxide equivalent emissions.
