[0002] In recent years, global attention to climate change has been increasing, and countries have taken action to reduce carbon emissions. Internationally, some developed countries and organizations began to study the carbon footprint of products as early as ten years ago, and adopted the Product Environmental Footprint (PEF) as a certification standard. In China, the current standards mainly use organizations as the accounting boundary, but some people believe that the carbon footprint of the production process is more in line with national trends and requirements. However, the relevant management methods are still imperfect, and there are difficulties in promoting and effectively managing the work of product carbon footprint.

[0003] At present, the existing carbon footprint management methods mainly cover carbon asset assessment, carbon quota management, carbon trading decision-making, carbon emission monitoring, carbon emission reduction project management, carbon footprint generation, data analysis and display, etc. The goal is to achieve effective management and optimal allocation of carbon assets through scientific and technological means and intelligent management platforms to promote the development of a low-carbon economy and environmental protection. That is, it can be applied to different industries and organizations to help companies achieve fine management of carbon emissions, reduce carbon emissions, and participate in the carbon trading market.

[0004] However, with the proposal of the "dual carbon" goal and the gradual deepening of carbon asset management, the existing carbon footprint management methods all use the enterprise as the boundary to calculate carbon emissions and are unable to accurately calculate products, making it impossible to accurately formulate product emission reduction strategies.

[0052] Embodiment 1

[0053] Please refer to Figure 1 , Figure 1 : is a flow chart of a product carbon emission reduction processing method provided by an embodiment of the present invention, the method comprising the following steps:

[0054] S100, find the production link corresponding to the target product from the pre-built carbon emission quantification requirement knowledge graph;

[0055] It should be noted that the product carbon footprint refers to the greenhouse gas emissions generated directly and indirectly during the entire life cycle of the product. The product life cycle includes production links such as raw material acquisition, manufacturing, transportation, use and waste disposal, and each stage will generate greenhouse gas emissions. The product carbon footprint is usually expressed in carbon dioxide equivalent (CO 2 e). Carbon dioxide is the main greenhouse gas, but the contribution of other greenhouse gases (such as methane, nitrogen oxides, etc.) is also taken into account and converted into equivalent emissions of carbon dioxide. Product carbon footprint can be measured by weight, volume or energy consumption.

[0056] It should be noted that, in the embodiment of the present invention, the production link corresponding to the target product can be all production links in the life cycle of the target product, or a certain production link in the life cycle of the target product, or a specific production link. The embodiment of the present invention does not specifically limit this, and it can be selected according to application requirements.

[0057] The pre-built carbon emission quantification requirements knowledge graph refers to a graphical representation method for displaying and organizing knowledge related to carbon emission quantification. In the field of carbon emission quantification, the knowledge graph can help organize and connect various carbon emission quantification concepts, methods, indicators, data and other information, so that the relationships and connections between these knowledge can be clearly displayed.

[0058] In one embodiment, the pre-built carbon emission quantification requirement knowledge graph is obtained by:

[0059] The first step is to collect standards and guidelines: normative documents developed by various industries or fields, including but not limited to standards, guidelines, procedures, etc. These documents are usually issued by industry organizations, national institutions or international organizations to regulate products, services or behaviors, including but not limited to: international standard "ISO14067: 2018 Greenhouse Gas-Product Carbon Footprint-Quantitative Requirements and Guidelines", EU Product Environmental Footprint PEF (Product Environment Footprint), British Standards Institution "PAS2050: Specification for the Assessment of Greenhouse Gas Emissions of Goods and Services during the Life Cycle", and "Product Life Cycle Accounting and Reporting Standard" jointly issued by WRI / WBCSD.

[0060] Step 2: Preprocessing of Text Data: Clean and normalize the collected text data, including removing stop words (such as "de", "shi", "zai", etc.) and punctuation marks, and converting the case of letters to make the text data more standardized and easy to analyze.

[0061] Step 3, Parsing the Document: Parse the preprocessed text data to extract information such as document structure, chapters, and paragraphs. This can be achieved through natural language processing techniques such as word segmentation, part-of-speech tagging, and syntactic analysis.

[0062] Step 4, Natural Language Processing (NLP) Technology: A branch in the fields of artificial intelligence and computer science used to process and analyze human language. NLP technology can help us understand and process text data, including tasks such as text classification, keyword extraction, and topic modeling.

[0063] Step 5, Keyword Extraction: Identify and extract the most representative and important words from the parsed text. These keywords can be used to determine the theme and key content of the text.

[0064] Step 6, Topic Modeling: Discover hidden themes or topics from a large amount of text data through NLP technology. Topic modeling can help us understand the structure and content of text data and conduct further analysis and mining.

[0065] Step 7, Clustering and Grid Analysis: Conduct clustering or grid analysis on the extracted information to discover the relationships and similarities between different components. Clustering can group related standards or guidelines, and grid analysis can display the relationships and differences between different components through visualization methods.

[0066] Step 8, Interactive Chart and Graph Display: Use visualization technology to present the analysis results in the form of charts or graphs to highlight the structure, connections, and key content of the standards and guidelines.

[0067] In one embodiment, when there is no carbon emission quantification-related knowledge associated with the target product in the pre-constructed knowledge graph of carbon emission quantification requirements, it is necessary to establish a quantification and evaluation method for the target product, including but not limited to: evaluation process, functional unit, system boundary, data requirements, inventory analysis, etc.

[0068] In one embodiment, by updating carbon footprint standards and guidelines in real time, the accuracy of the pre-constructed knowledge graph of carbon emission quantification requirements can be improved.

[0069] It is understandable that the pre-built carbon emission quantification requirements knowledge graph is a kind of knowledge graph that displays and organizes carbon emission quantification related knowledge for all products. In practical applications, what we need is the carbon footprint of a specific product. Therefore, we can find the production link corresponding to the product from the pre-built carbon emission quantification requirements knowledge graph.

[0070] S200, matching the target product production link with a preset greenhouse gas emission table to determine the calculation parameters of greenhouse gases in the target product production link under various emission modes; wherein the preset greenhouse gas emission table includes the corresponding relationship between the target product production link and the calculation parameters of greenhouse gases under the emission mode;

[0071] It should be noted that evaluating the carbon footprint of the target product is to evaluate the greenhouse gas emissions of the target product, and the greenhouse gas emissions of the product come from equipment energy consumption emissions, equipment venting emissions, pipeline equipment fugitive emissions, etc., and the calculation of the greenhouse gas emissions of the product under various emission modes requires relevant calculation parameters, that is, the calculation parameters of greenhouse gases under various emission modes in the embodiment of the present invention. In addition, for different products, the sources of their greenhouse gas emissions are also different, and the corresponding greenhouse gas calculation parameters under various emission modes are also different.

[0072] The calculation parameters of greenhouse gases under various emission modes include: greenhouse gas combustion emission calculation parameters, greenhouse gas venting emission calculation parameters and greenhouse gas fugitive emission calculation parameters. Among them, greenhouse gas combustion emission calculation parameters include: energy consumption and usage time of multiple power equipment under multiple active operations; greenhouse gas venting emission calculation parameters include: gas venting flow, gas venting time and greenhouse gas concentration of multiple power equipment under multiple active operations; greenhouse gas fugitive emission calculation parameters include: gas fugitive flow, gas fugitive time and greenhouse gas concentration of multiple sealing points under multiple pipeline equipment.

[0074]

[0075] Table 1 Preset greenhouse gas emissions table

[0076] The preset greenhouse gas emission table is used to characterize the mapping relationship between products and calculation parameters of greenhouse gases under different emission modes.

[0077] In one embodiment, the preset greenhouse gas emission table can be implemented in the following ways: collect the sources of greenhouse gas emissions of the target product in the stages of raw material acquisition, production, transportation, use and waste treatment through field surveys, and the greenhouse gases mainly considered are carbon dioxide (CO 2 ), methane (CH4 ) and nitrous oxide (N 2 O), the main emission modes considered are fuel energy combustion emissions, venting emissions and fugitive emissions, so as to determine the greenhouse gas emissions of the target product in each production link during its life cycle. If some data cannot be obtained through field research, reliable and accurate data can be obtained through industry reports, government databases and scientific literature.

[0078] For ease of understanding, the following is a detailed description in conjunction with the aforementioned Table 1:

[0079] As shown in Table 1, taking natural gas as an example, Table 1 only exemplifies the extraction stage of natural gas in its entire life cycle. From Table 1, it can be seen that the extraction stage of natural gas corresponds to three calculation parameters, namely, greenhouse gas combustion emission calculation parameters, greenhouse gas venting emission calculation parameters and greenhouse gas fugitive emission calculation parameters.

[0080] The calculation parameters of greenhouse gas combustion emissions are the energy consumption of power equipment used in various activities during the natural gas extraction stage. For example: excavators (power, fuel consumption, construction cycle and quantity) and bulldozers (power, fuel consumption, construction cycle and quantity) used in pre-drilling projects; drilling rigs (quantity, power, drilling rig cycle, fuel type, fuel usage) and generator sets (quantity, power, drilling rig cycle, fuel type, fuel usage) used in drilling projects. The calculation parameters of combustion emissions for other activities can be compared with Table 1, which will not be repeated here.

[0081] The greenhouse gas venting emission calculation parameters are the venting emissions of power equipment used in various activities during the natural gas extraction stage. For example: the gas flow rate and methane concentration of the drill pipe test venting used in drilling projects; the gas flow rate and methane concentration of the fracturing fluid backflow dissolved and carried gas venting used in hydraulic fracturing projects. The venting emission calculation parameters of other activities can be compared with Table 1, which will not be repeated here.

[0082] The calculation parameters for greenhouse gas fugitive emissions are the fugitive emissions from each sealing point under each pipeline equipment during the natural gas extraction stage. For example: valve fugitive gas flow rate and methane concentration; flange fugitive gas flow rate and methane concentration. The calculation parameters for fugitive emissions of other activities can be compared with Table 1 and will not be repeated here.

[0083] In one embodiment, it is necessary to perform uncertainty analysis on greenhouse gas combustion emission calculation parameters, greenhouse gas venting emission calculation parameters, greenhouse gas fugitive emission calculation parameters, preset energy emission factors and preset greenhouse gas emission factors, including but not limited to: statistical analysis, sensitivity analysis, Monte Carlo simulation, uncertainty transfer analysis and hypothesis testing. The embodiment of the present invention does not make specific limitations on this, and a reasonable selection can be made according to the specific problem, data type, data volume and analysis purpose.

[0084] The following is an introduction to the commonly used methods of uncertainty analysis:

[0085] 1. Statistical analysis: By collecting a certain amount of data and applying statistical principles and methods to analyze, the mean, standard deviation, confidence interval, etc. of the data can be calculated to assess the uncertainty of the data.

[0086] 2. Sensitivity analysis: By systematically modifying the input parameters and observing the changes in the results, we can understand the impact of the parameters on the results. You can use univariate sensitivity analysis, multivariate sensitivity analysis, etc.

[0087] 3. Monte Carlo simulation: Random sampling of input parameters is used to perform multiple simulations to obtain the distribution of results. Simulation samples can be generated through random sampling, probability distribution functions, etc. to assess uncertainty.

[0088] 4. Uncertainty transfer analysis: According to the principle of uncertainty, the uncertainty of each input parameter is transferred to the result. The transfer function, linear transfer, Monte Carlo transfer and other methods can be used for analysis.

[0089] 5. Hypothesis testing: Assess the uncertainty of the data by comparing the results with the hypothesis to determine whether they are statistically significant.

[0090] In one embodiment, greenhouse gas combustion emission calculation parameters, greenhouse gas venting emission calculation parameters, greenhouse gas fugitive emission calculation parameters, preset energy emission factors and preset greenhouse gas emission factors should be temporally representative, geographically representative and consistent, and missing data should be documented.

[0091] S300, determining the emission of greenhouse gases in the production link of the target product under various emission modes based on calculation parameters of greenhouse gases in the production link of the target product under various emission modes;

[0092] It should be noted that the calculation methods of greenhouse gas emissions under various emission modes are different. The following examples are given:

[0093] For example, greenhouse gas emissions are calculated by calculating the carbon dioxide content produced after the combustion of energy (oil, natural gas, etc.). Therefore, the total energy consumption of the power equipment during its use time is calculated by multiplying the energy consumption of the power equipment by the use time of the power equipment, and then multiplying it by the energy emission factor (unit: tons / year·Nm 3 ), while the energy emission factor represents the carbon dioxide content emitted by the fuel, which can ultimately calculate the carbon dioxide emissions of the power equipment during its use time.

[0094] For example, greenhouse gas venting emissions, since it is a direct emission of greenhouse gases, the amount of emissions can be counted. There are two specific methods: actual measurement calculation method and emission factor method. The actual measurement calculation method is: the gas flow rate of the equipment venting * venting time * greenhouse gas concentration, and the emission factor method is: the number of greenhouse gas venting equipment * greenhouse gas venting emission factor (unit: tons / 100 million Nm 3 or tons), an emission factor is a measure of the carbon dioxide (CO 2 ) emissions, which represents the amount of carbon dioxide emissions produced by a unit activity or process, and thus the carbon dioxide emissions of the equipment can be calculated.

[0095] For example, greenhouse gas fugitive emissions, since it is a greenhouse gas emitted directly, the amount of fugitive emissions can be counted. There are two specific methods: actual measurement calculation method and emission factor method. The actual measurement calculation method is: the gas flow rate of the equipment fugitive emission * the fugitive emission time * the concentration of greenhouse gas. The emission factor method is: the number of equipment that counts greenhouse gas fugitive emissions * greenhouse gas fugitive emission factor (unit: tons / year / unit). The emission factor is a measure of the carbon dioxide (CO2) generated by a specific activity or process. 2 ) emissions, which represents the amount of carbon dioxide emissions produced by a unit of activity or process, from which the fugitive carbon dioxide emissions of the equipment can ultimately be calculated.

[0096] In addition, different greenhouse gas emission sources correspond to different emission factors, and the carbon footprint of each product includes different greenhouse gas emission sources, so each product includes multiple different types of emission factors.

[0097] In one embodiment, the energy emission factor, greenhouse gas venting emission factor and greenhouse gas fugitive emission factor can refer to the "China Product Life Cycle Greenhouse Gas Emission Factor Database" or the "China Petroleum and Natural Gas Production Enterprise Greenhouse Gas Emission Accounting Method and Reporting Guide (Trial)".

[0098] It should be noted that greenhouse gas venting emissions are calculated for greenhouse gases (methane, nitrous oxide). In order to unify the calculation standard, we need to multiply the calculated greenhouse gas venting emissions by the global warming potential (GWP) of the greenhouse gas to obtain the carbon dioxide venting emissions. Among them, the global warming potential (GWP) of different greenhouse gases is different, and the global warming potential (GWP) of different greenhouse gases will also change numerically over time, and the embodiments of the present invention do not specifically limit this.

[0099] In one embodiment, step S300 may be implemented in the following manner:

[0100] S310, using formula (1), calculating the energy consumption, usage time and preset energy emission factors of multiple power equipment under multiple activities in the production link of the target product, and obtaining the greenhouse gas combustion emissions in the production link of the target product;

[0103] In one embodiment, when the energy consumption of the power equipment is difficult to measure or obtain, the power equipment model can be obtained, and the power equipment rated power*usage time*energy emission factor can be used. The specific calculation rules are as follows:

[0104] Among them, E 燃烧排放 Indicates the greenhouse gas combustion emissions in the production process of the target product; It represents the rated power of the jth power equipment under the i-th activity operation in the production link of the target product; It represents the usage time of the jth power equipment under the i-th activity operation in the production link of the target product; It represents the preset energy emission factor of the jth power equipment under the ith activity operation in the production link of the target product; n represents the number of power equipment under the ith activity operation in the production link of the target product, that is, j = 1, 2, 3...n.

[0109] Among them, E 放空排放 Indicates the greenhouse gas emissions during the production process of the target product; It represents the number of j-th power equipment under the i-th activity operation in the production link of the target product; It represents the venting emission factor of the jth power equipment under the ith activity in the production process of the target product; GWP represents the global warming potential of greenhouse gases; n represents the number of power equipment under the ith activity in the production process of the target product, that is, j = 1, 2, 3...n.

[0110] S330, using formula (3), calculate the gas escape flow rate, gas escape time, greenhouse gas concentration and preset greenhouse gas emission factor of multiple sealing points under multiple pipeline equipment in the production link of the target product to obtain the greenhouse gas escape emission in the production link of the target product;

[0111]

[0112] Among them, E 逸散排放 Indicates the amount of greenhouse gas fugitive emissions during the production process of the target product; It represents the gas escape flow rate at the jth sealing point under the i-th pipeline equipment in the production link of the target product; Indicates the gas escape time of the jth sealing point under the i-th pipeline equipment in the production link of the target product; It represents the greenhouse gas concentration at the jth sealing point under the i-th pipeline equipment in the production link of the target product; GWP represents the global warming potential of the greenhouse gas; n represents the number of sealing points under the i-th pipeline equipment in the production link of the target product, that is, j = 1, 2, 3...n.
