Description

Technical Field

[0001] The present application relates to the technical field of carbon emission calculation, and in particular to a method and device for calculating implicit carbon emissions in the bulk building materials industry. Background Art

[0002] In the related art, when calculating the carbon emissions of building materials products, it is usually based on the carbon emissions of the production process of the building materials products or the production plant. That is, the carbon emissions of building materials products are determined by the carbon dioxide emissions generated by combustion in the building materials production process and the carbon dioxide emitted in the industrial fuel combustion process.

[0003] However, the direct carbon emission accounting methods in related technologies usually only focus on the direct carbon emissions of building materials, while ignoring the indirect carbon emissions in the upstream and downstream of the supply chain, underestimate the overall carbon emissions of the building materials industry, and it is difficult to accurately reflect the carbon emission characteristics of the building materials industry; and the calculation of carbon emissions is often concentrated on some single industries or fields, while ignoring the complexity of the links and regional complexity involved in the carbon emissions of the building materials industry. For example, there are significant differences in building materials production, energy consumption, economic structure and development level among regions. The building materials consumption in some regions may depend on the production of building materials in other regions. There are also differences in the production and consumption of the building materials industry. Only focusing on carbon emissions in local areas, ignoring the mobility and differences of carbon emissions between regions, it is impossible to deeply analyze the carbon emission characteristics of the entire chain of the building materials industry, and it is difficult to quantify the flow characteristics of carbon emissions between regions. The calculation accuracy of carbon emissions in the building materials industry is insufficient, which needs to be solved urgently. Summary of the invention

The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present application, and should not be construed as limiting the present application.

[0041] The following describes the implicit carbon emission calculation method and device of the bulk building materials industry of the embodiment of the present application with reference to the accompanying drawings. The carbon emission calculation in the related art mentioned in the above background technology usually only focuses on the direct carbon emission of building materials and is concentrated in some single industries or fields, while ignoring the indirect carbon emissions of the upstream and downstream of the supply chain and the mobility and differences of carbon emissions between regions. It is impossible to deeply analyze the carbon emission characteristics of the entire chain of the building materials industry, it is difficult to quantify the flow characteristics of carbon emissions between regions, and the problem of implicit carbon emissions in the building materials industry is not paid attention to. The present application provides a method for calculating the implicit carbon emissions of the bulk building materials industry. In this method, an input-output table can be established based on the input-output method, so as to construct a complete consumption coefficient matrix combined with the direct carbon emission intensity of each industrial sector, and establish an implicit carbon emission matrix of bulk building materials in a single region and / or multiple regions, and finally calculate the implicit carbon emissions of bulk building materials in a single region and / or multiple regions. As a result, a special design of the sector classification of the input-output table of the building materials industry is achieved, which can deeply analyze the carbon emission characteristics of the entire chain of the building materials industry, and quantify the implicit carbon emission structure and flow within the bulk building materials industry and between other industries; the input-output accounting method is used to account for direct and indirect carbon emissions in the production and consumption process of the bulk building materials industry, which can reflect the carbon emission flow characteristics between the bulk building materials industry and other industries, and make up for the defect of related technologies that ignore implicit carbon emissions; the introduced multi-regional input-output model can fully consider the carbon emission characteristics of different regions and the carbon emission flow between regions, and can accurately identify the carbon emission characteristics and emission reduction potential of different regions, effectively improving the accuracy of the implicit carbon emissions of the bulk building materials industry in this application, and providing data support for the design of regional carbon emission reduction policies. This solves the problem that carbon emission calculations in related technologies usually only focus on direct carbon emissions from building materials and are concentrated in some single industries or fields, while ignoring indirect carbon emissions in the upstream and downstream of the supply chain and the fluidity and differences of carbon emissions between regions. It is impossible to deeply analyze the carbon emission characteristics of the entire chain of the building materials industry, it is difficult to quantify the flow characteristics of carbon emissions between regions, and there is no attention paid to the implicit carbon emissions in the building materials industry.

[0042] Specifically, Figure 1 A flow chart of a method for calculating embodied carbon emissions in the bulk building materials industry provided in an embodiment of the present application.

[0043] like Figure 1 As shown in the figure, the calculation method of embodied carbon emissions in the bulk building materials industry includes the following steps:

[0044] In step S101, at least one industrial sector of the input and output of the bulk building materials industry is obtained, and an input-output table of the bulk building materials industry is established based on the input-output method and at least one industrial sector.

[0045] It is understandable that the bulk building materials industry here can be understood as those raw materials that are large in size, large in quantity, and whose prices may fluctuate greatly. These materials can be widely used in construction, energy, transportation, machinery and other industries, for example, basic raw materials such as cement, glass, glass fiber, and gypsum board.

[0046] Figure 2 This is a schematic diagram of a framework for calculating the implicit carbon emissions of the bulk building materials industry based on input and output in one embodiment of the present application. Figure 2 As shown, the embodiment of the present application can use the input-output method to calculate the embodied carbon emissions of the bulk building materials industry. Among them, the input-output method is an economic quantitative analysis method that studies the interdependence between various sectors in the economic system in terms of input and output. The input-output table is a chessboard-like balance table composed of the input sources and product usage destinations in the production of products in various sectors of the national economy. Figure 3 This is a schematic diagram of an input-output table of an embodiment of the present application.

[0047] Based on the input-output table, we can understand which industrial sectors have input and output in the bulk building materials industry. Combining these industrial sector information and greenhouse gas emission coefficients, the embodiment of the present application can transform the complex economic relationship between industries into a physical association of carbon emissions. Therefore, the embodiment of the present application can quantitatively analyze the carbon emission flow array between multiple industrial sectors, including but not limited to direct carbon emissions generated by the consumption of fossil energy by industrial sectors and indirect carbon emissions generated by the consumption of intermediate products.

[0048] The embodiments of the present application may adopt an input-output accounting method, which can reflect the carbon emission flow characteristics between the bulk building materials industry and other industries, and then calculate the direct and indirect carbon emissions in the production and consumption process of the bulk building materials industry, thereby making up for the defect of ignoring implicit carbon emissions in related technologies.

[0049] Optionally, in one embodiment of the present application, an input-output table for the bulk building materials industry is established based on the input-output method and at least one industrial sector, including: drawing an implicit carbon emission accounting data table for the bulk building materials industry based on the target data source and the input-output method; and establishing an input-output table based on the implicit carbon emission accounting data table.

[0050] In the actual implementation process, when constructing the input-output table, this application can determine the industrial sectors related to the embodied carbon emissions of the bulk building materials industry based on multiple target data sources. Among them, the target data source here can be understood as the source or source of the data used when establishing the embodied carbon emissions accounting data table of the bulk building materials industry.

[0051] For example, the target data sources in the embodiments of the present application include but are not limited to: the publicly available "China Input-Output Table (153 Departments)" and "China Input-Output Table (42 Departments)" of the National Bureau of Statistics, China Carbon Accounting Databases (CEADs), "China Energy Statistical Yearbook" (energy balance sheets may be delayed), "Guidelines for the Preparation of Provincial Greenhouse Gas Inventories", "2006 IPCC National Greenhouse Gas Inventory Guidelines" and related literature information, etc. Table 1 is a table of implicit carbon emission accounting data for the bulk building materials industry drawn in the embodiments of the present application based on these target data sources, which can be expressed as follows:

[0052] Table 1

[0053]

[0054]

[0055] Furthermore, in view of the differences in the definition of sectors in different data sources, in order to ensure the consistency of the data, the embodiment of the present application may, but is not limited to, adjust the economic sectors in the input-output table to 36 sectors, including but not limited to seven major building materials sectors: cement, lime and gypsum manufacturing industry; brick, tile, stone and other building materials manufacturing industry; glass and glass products manufacturing industry; ceramic products manufacturing industry; refractory products manufacturing industry; graphite and other non-metallic mineral products manufacturing industry; and ferrous metal smelting and rolling processing industry.

[0056] Among them, the merging (adjustment) principle in the embodiment of the present application is based on the "National Economic Industry Classification and Code" on the basis of ensuring the consistency of the statistical caliber of the energy statistical yearbook and the input-output table and meeting the research needs of bulk building materials.

[0057] (GB / T 4754-2002), all industrial sectors are finally merged into 36 sectors. Table 2 is a schematic diagram of sector division in an embodiment of the present application, which can be expressed as follows:

[0058] Table 2

[0059]

[0060]

[0061] It should be noted that the specific data sources and whether or not to merge and the principles of merging can be adjusted by professionals in this field according to actual conditions. The embodiments of this application are only illustrative and not specifically limited.

[0062] The embodiments of the present application can merge and divide the department classification of the input-output table of the building materials industry, deeply analyze the carbon emission characteristics of the entire chain of the building materials industry, quantify the implicit carbon emission structure and flow within the bulk building materials industry and between other industries, and contribute to the carbon emission management and policy formulation of the building materials industry.

[0063] Step S102: Based on the input-output table and at least one industrial sector, a complete consumption coefficient matrix is ​​constructed and the direct carbon emission intensity of at least one industrial sector is calculated. The complete consumption coefficient matrix can be, but is not limited to, represented as:

[0064]

[0065] Among them, B is the complete consumption coefficient matrix, A is the direct consumption coefficient matrix, I is the unit matrix, and b ij (i,j=1,2,…,n) represents the complete consumption coefficient.

[0066] Based on the relevant descriptions of other embodiments, it can be understood that the embodiment of the present application can establish an input-output table for the bulk building materials industry based on the input-output method, and the carbon emission flow relationship between the bulk building materials industry and other industrial sectors can be obtained based on the input-output table.

[0067] As a possible implementation method, the embodiment of the present application can construct a direct consumption coefficient matrix based on the input-output table and at least one sector in the input-output table, so as to obtain a complete consumption coefficient matrix based on the direct consumption coefficient matrix to calculate the direct carbon emission intensity of at least one industrial sector.

[0068] For example, the application can use the input-output table to obtain several coefficients / parameters reflecting the relationship between the input and output of various industrial sectors in the bulk building materials industry, and then use the direct consumption coefficients therein to establish a direct consumption coefficient matrix. The direct consumption coefficient matrix can be used to represent the direct consumption relationship between sectors, and its form can be, but is not limited to, as follows:

[0069]

[0070] Among them, A is the direct consumption coefficient matrix, a ij represents the direct consumption coefficient, x ij represents the value of the products of industry sector i that are directly consumed by industry sector j in production and operation, X j represents the total input of industry sector j.

[0071] In the embodiment of the present application, the most important coefficient is the complete consumption coefficient. The complete consumption coefficient matrix established based on the complete consumption coefficient can be used to represent the sum of direct consumption and indirect consumption of products of each department driven by the production of the final product:

[0072]

[0073] Among them, B is the complete consumption coefficient matrix, A is the direct consumption coefficient matrix, I is the unit matrix, and b ij (i,j=1,2,…,n) represents the complete consumption coefficient.

[0074] By using the complete consumption coefficient matrix, the embodiment of the present application can calculate the direct carbon emissions and implicit carbon emissions of at least one industrial sector.

[0075] Optionally, in one embodiment of the present application, the direct carbon emission intensity of at least one industrial sector is calculated, including: calculating the carbon emissions corresponding to the fossil energy consumption of at least one industrial sector and the carbon emissions generated by industrial processes; determining the direct carbon emissions of at least one industrial sector based on the carbon emissions corresponding to the fossil energy consumption and the carbon emissions generated by industrial processes, so as to determine the direct carbon emission intensity based on the direct carbon emissions and the output value of at least one industrial sector.

[0076] Based on the relevant descriptions of other embodiments, it can be understood that the present application can use the direct consumption matrix to calculate the direct carbon emission intensity of at least one industrial sector, wherein the direct carbon emission intensity can be determined by the calculated direct carbon emissions.

[0077] In the embodiment of the present application, direct carbon emissions can be defined as carbon emissions caused by fossil energy consumption in the production process of a certain department and carbon emissions generated by industrial processes. The formula can be, but is not limited to, expressed as follows:

[0078] C i =C ie +C it ,

[0079] Among them, C i is the direct carbon emission, C ie is the carbon emissions caused by fossil energy consumption in industry sector i, C it is the carbon emissions generated by industrial processes in industry sector i.

[0080] In actual calculation, the present application may, but is not limited to, calculate the direct carbon dioxide emissions of at least one industrial sector regarding fossil energy consumption according to the IPCC (Intergovernmental Panel on Climate Change) carbon emission inventory guidelines, and the formula may, but is not limited to, be expressed as follows:

[0081]

[0082] Among them, EC ie NCV is the consumption of the e-th energy by industry sector i; eis the average low calorific value of the e-th energy source; CEF e COF is the carbon content per unit calorific value of the e-th energy source; e is the carbon oxidation rate of the e-th energy source; is the molar mass ratio of CO2 and C.

[0083] Furthermore, the carbon dioxide emissions generated by the industrial process in the embodiment of the present application can be calculated by, but not limited to, the product amount and the carbon emission factor in the industrial process, and the formula can be, but not limited to, expressed as follows:

[0084] C it =EC it ×EF it ,

[0085] Among them, C it is the carbon emissions generated by industrial processes in industry sector i, EC it is the output of industrial sector i in industrial process t, EF it is the carbon emission factor.

[0086] Finally, the direct carbon emission intensity can be obtained by the ratio of direct carbon emissions of at least one industrial sector to its output value. The formula can be, but is not limited to, as follows:

[0087] d i =C i / X i ,

[0088] Among them, d i represents the direct carbon emissions of at least one industrial sector, X i is the total output of industry sector i.

[0089] Step S103, based on the complete consumption coefficient matrix and the direct carbon emission intensity, establish an implicit carbon emission matrix of at least one industrial sector in a single region and / or multiple regions, so as to calculate the implicit carbon emissions of the bulk building materials industry in the single region and / or multiple regions according to the implicit carbon emission matrix. The implicit carbon emission matrix in the single region and / or multiple regions can be, but is not limited to, expressed as:

[0090] TC=diag(d i )×(IA d ) -1 ×Y d

[0091]

[0092] Among them, TC represents the implicit carbon emission matrix of each sector, diag(d i ) is a diagonal matrix consisting of the direct carbon emission intensity of each industrial sector, (IAd ) -1 and (IA) -1 are all Leontief inverse matrices, which can reflect the complex economic connections between industrial sectors. I is the unit matrix, and A d is the direct consumption coefficient matrix after removing imports; Y d It is a diagonal matrix consisting of the final demands corresponding to each industrial sector; is a diagonal matrix composed of the direct carbon emission intensity of each industrial sector in each region, A is the direct consumption coefficient matrix of the multi-region input-output table, Y is the diagonal matrix composed of the final demand corresponding to each industrial sector in each region, TC s It is represented as the implicit carbon emission matrix of each region and sector.

[0093] It is understood by professionals in this technical field that, according to the different research scopes, the input-output model can be divided into a single-region input-output model and a multi-region input-output model. The multi-region input-output model (MRIO) can comprehensively and systematically reflect the economic connection between regional industries through the trade flows between regions, and is an important tool for analyzing the relevant connections and impacts of various industrial sectors in different regions. Combining the regional input-output table with the environmental impact coefficient can clarify the resource consumption or pollutant emissions caused by the final demand of a certain region. For this reason, the regional input-output table is also often used to evaluate and analyze environmental issues.

[0094] In some embodiments, after calculating the complete consumption coefficient matrix and the direct carbon emission intensity of at least one industrial sector, the present application can establish a single-region implicit carbon emission matrix and / or a multi-region implicit carbon emission matrix of the at least one industrial sector based on the two, thereby calculating the single-region implicit carbon emissions and / or multi-region implicit carbon emissions of the bulk building materials industry based on the single-region implicit carbon emission matrix and / or the multi-region implicit carbon emission matrix.

[0095] When calculating the embodied carbon emissions in a single region, the embodiment of the present application can be, but is not limited to, calculated based on the EIO-LCA model (economic input-output-life cycle assessment model) and the single-region embodied carbon emission matrix of each industrial sector. Among them, the EIO-LCA model is a top-down life cycle analysis method based on the input-output table, which can reflect the economic and technical connections between departments through the economic input-output table, thereby calculating the energy consumption and emission levels at the department level, and then estimating the carbon emissions and environmental impact of products or services using the input-output table; and, the single-region embodied carbon emission matrix in the embodiment of the present application can be, but is not limited to, expressed as follows:

[0096] TC=diag(d i )×(IA d ) -1 ×Yd

[0097] Among them, diag(d i ) is a diagonal matrix consisting of the direct carbon emission intensity of each industrial sector; (IA d ) -1 is the Leontief inverse matrix, which can reflect the complex economic relations between industrial sectors and can be determined by the complete consumption coefficient matrix; I is the unit matrix; A d is the direct consumption coefficient matrix after removing imports; Y d It is a diagonal matrix consisting of the final demands corresponding to each industrial sector.

[0098] Based on the relevant descriptions of other embodiments, it can be understood that the direct carbon emission intensity in the embodiments of this application can be understood as the ratio of the direct carbon emissions of each industrial sector to its output value. The direct carbon emission intensity matrix of industrial sector i in region s is represented. The calculation formula of direct carbon emission intensity can be, but is not limited to, expressed as follows:

[0099]

[0100] in, is the direct carbon emissions of industrial sector i in region s, is the total output of industry sector i in region s.

[0101] Similarly, when calculating the embodied carbon emissions in multiple regions, the embodiment of the present application may be, but is not limited to, calculated based on the multi-regional input-output model (MRIO) and the multi-regional embodied carbon emission matrix of each industrial sector, wherein the multi-regional embodied carbon emission matrix may be, but is not limited to, obtained by the direct carbon emission intensity matrix and the input-output consumption coefficient matrix in the embodiment of the present application, and the multi-regional embodied carbon emission matrix may be, but is not limited to, expressed as follows:

[0103] in, It is a diagonal matrix composed of the direct carbon emission intensity of each region and each industrial sector; (IA) -1 is the Leontief inverse matrix, which can reflect the complex economic relations between industrial sectors and can be determined by the complete consumption coefficient matrix; I is the unit matrix; A is the direct consumption coefficient matrix of the multi-regional input-output table; Y is the diagonal matrix composed of the final demand corresponding to each industrial sector in each region; TC s It is represented as the implicit carbon emission matrix of each region and sector.

[0104] Finally, after calculating the single-region embodied carbon emission matrix and the multi-region embodied carbon emission matrix, the embodied carbon emissions of the bulk building materials industry in a single region and the embodied carbon emissions in multiple regions can be obtained based on the single-region embodied carbon emission matrix and the multi-region embodied carbon emission matrix respectively.

[0105] It should be noted that, in actual application, you can choose to apply a single-region implicit carbon emission matrix and / or a multi-region implicit carbon emission matrix according to actual conditions or actual needs. For example, if you only need to calculate the implicit carbon emissions of the bulk building materials industry in a single region, you can only select the single-region implicit carbon emission matrix. If you only need to calculate the implicit carbon emissions of the bulk building materials industry in multiple regions, you can only select the multi-region implicit carbon emission matrix. If you need to calculate the implicit carbon emissions of the bulk building materials industry in multiple regions and at the same time need to clarify the implicit carbon emissions of the bulk building materials industry in each single region, you can select both the single-region implicit carbon emission matrix and the multi-region implicit carbon emission matrix. The embodiments of this application do not impose specific restrictions.

[0106] The embodiments of the present application can calculate the embodied carbon emissions of the bulk building materials industry in a single region and in multiple regions respectively, and introduce a multi-regional input-output model, which fully considers the carbon emission characteristics of the bulk building materials industry in different regions and the carbon emission flow between regions. It can accurately identify the carbon emission characteristics and emission reduction potential in different regions, effectively improve the accuracy of the embodied carbon emissions of the bulk building materials industry in this application, and can provide strong data support for the design of regional carbon emission reduction policies.

[0107] Optionally, in one embodiment of the present application, based on the complete consumption coefficient matrix and direct carbon emission intensity, an implicit carbon emission matrix of at least one industrial sector in a single region and / or multiple regions is established, including: obtaining at least one influencing factor of the input and output of the bulk building materials industry; based on the complete consumption coefficient matrix, direct carbon emission intensity and at least one influencing factor, an implicit carbon emission matrix of at least one industrial sector in a single region and / or multiple regions is established.

[0108] During the actual implementation process, when establishing a single-region embodied carbon emission matrix and / or a multi-region embodied carbon emission matrix for at least one industrial sector, it is taken into account that the bulk building materials industries in a single region and in multiple regions are affected by different factors. For example, the embodied carbon emissions of the bulk building materials industry in a single region do not involve the impact of the import and export of bulk building materials products, while the embodied carbon emissions of the bulk building materials industry in multiple regions may involve the impact of the import and export of bulk building materials products. Therefore, the embodiment of the present application needs to obtain at least one influencing factor of the input and output of bulk building materials products. While considering the at least one influencing factor, the embodied carbon emission matrix of at least one industrial sector in a single region and / or multiple regions is established in combination with the complete consumption coefficient matrix and the direct carbon emission intensity.

[0109] For example, China's multi-regional input-output table is a non-competitive input-output table, that is, the intermediate use and final use of the input-output table have been distinguished according to domestic products and imports. Therefore, the difference between the construction of the implicit carbon emission matrix in a single region and the implicit carbon emission matrix in multiple regions lies in whether the impact of imports needs to be removed.

[0110] For example, in a general input-output model, the direct carbon emission coefficient matrix A and the final demand Y are both based on the homogeneity of imported products, that is, imports are not distinguished. Therefore, in order to avoid overestimating the carbon emissions of the bulk building materials industry and make the calculation results closer to the actual value, the embodiment of the present application needs to remove the impact of imports when constructing the implicit carbon emission matrix in a single region, and derive the direct consumption coefficient matrix A that only includes domestic bulk building materials products. d and the final demand matrix Y d .

[0111] A d =(IS)×A,

[0112] Y d =(IS)×Y c +Y e ,

[0113]

[0114] Among them, m i is the import volume of industry sector i, X i is the total output of industry sector i, y ie is the export volume of industry sector i, and the import coefficient matrix S is a matrix with diagonal elements s i The diagonal matrix, Y c Y is the diagonal matrix consisting of the final demand of each industry sector excluding the export volume, e It is a diagonal matrix consisting of the export volume of each industrial sector.

[0115] According to the method for calculating the embodied carbon emissions in the bulk building materials industry proposed in the embodiment of the present application, an input-output table can be established based on the input-output method, thereby constructing a complete consumption coefficient matrix combined with the direct carbon emission intensity of each industrial sector to establish an embodied carbon emission matrix for bulk building materials in a single region and / or multiple regions, and finally calculate the embodied carbon emissions of bulk building materials in a single region and / or multiple regions. As a result, a special design of the sector classification of the input-output table of the building materials industry is achieved, which can deeply analyze the carbon emission characteristics of the entire chain of the building materials industry, and quantify the implicit carbon emission structure and flow within the bulk building materials industry and between other industries; the input-output accounting method is used to account for direct and indirect carbon emissions in the production and consumption process of the bulk building materials industry, which can reflect the carbon emission flow characteristics between the bulk building materials industry and other industries, and make up for the defect of related technologies that ignore implicit carbon emissions; the introduced multi-regional input-output model can fully consider the carbon emission characteristics of different regions and the carbon emission flow between regions, and can accurately identify the carbon emission characteristics and emission reduction potential of different regions, effectively improving the accuracy of the implicit carbon emissions of the bulk building materials industry in this application, and providing data support for the design of regional carbon emission reduction policies. This solves the problem that carbon emission calculations in related technologies usually only focus on direct carbon emissions from building materials and are concentrated in some single industries or fields, while ignoring indirect carbon emissions in the upstream and downstream of the supply chain and the fluidity and differences of carbon emissions between regions. It is impossible to deeply analyze the carbon emission characteristics of the entire chain of the building materials industry, it is difficult to quantify the flow characteristics of carbon emissions between regions, and there is no attention paid to the implicit carbon emissions in the building materials industry.
