In the present invention, by obtaining the type of fuel used and the amount of fuel consumption, the amount of electricity purchased and the amount of electricity sold, the amount of heat purchased and the amount of heat sold, the type, consumption and purity of the carbon-containing substances of the target enterprise in the production process, the number of types of planted trees, the growth years of planted trees, the net primary productivity per unit area of ​​planted trees in the growth years and the forest area of ​​planted trees in the growth years, and the type and quality of greenhouse gases escaping in the production process, and selecting corresponding calculation coefficients, the corresponding fuel combustion emissions, electricity use emissions, heat use emissions, industrial production emissions, etc. are obtained.

When carbon-containing fossil energy is used as raw materials, the emissions generated by the use of energy as raw materials are calculated. After first separately calculating the greenhouse gas recycling and utilization amount, greenhouse gas sales amount and carbon fixation product offset amount, the offset emissions are calculated, as well as the target enterprise's purchased carbon offset amount, so that the target enterprise's carbon emissions can be finally calculated through addition and subtraction algorithms, which effectively simplifies the target enterprise's carbon emissions calculation process and improves accuracy.

[0080] The following describes the design scheme of the data processing method of enterprise carbon emissions through specific exemplary embodiments. It should be noted that the following embodiments are only used to explain the technical scheme of the invention and are not specifically limited:

[0081] See also Figure 1 The present invention provides a method for processing data of carbon emissions of an enterprise, and the method for processing data of carbon emissions of an enterprise comprises the following steps:

[0082] Aggregate and classify the computing systems of multiple industries in advance and embed them into the computing system;

[0083] Collect target enterprise data and calculate the carbon emissions of the enterprises;

[0084] S100, obtaining a fuel type and a fuel consumption used by a target enterprise, selecting a first calculation coefficient according to the fuel type, and calculating the fuel combustion emissions of the target enterprise using the fuel consumption and the first calculation coefficient.

[0085] Specifically, when calculating the fuel combustion emissions of the target enterprise, that is, calculating the greenhouse gas emissions generated by the complete combustion of fuel and oxygen in the target enterprise, you only need to first select any of the target enterprises to be calculated, and then select the fuel type used by the target enterprise, and enter the fuel consumption of the target enterprise. Then, the corresponding first calculation coefficient will be selected by default according to different fuel types. Finally, the fuel consumption and the first calculation coefficient are used to calculate the fuel combustion emissions of the target enterprise, thereby realizing the quick calculation of the fuel combustion emissions of the target enterprise. Among them, greenhouse gases are those natural and man-made gaseous components in the atmosphere that absorb and re-emit infrared radiation; greenhouse gases in this application refer to the six greenhouse gases specified in the Kyoto Protocol, namely carbon dioxide (CO 2 ), methane (CH 4 ), nitrous oxide (N 2 O), hydrofluorocarbons (HFCs), perfluorocarbons (PFCs) and sulfur hexafluoride (SF 6 ).

[0088] S120, respectively multiplying the fuel consumption of each fuel by the corresponding fuel carbon dioxide emission factor to obtain the sub-combustion emission of each fuel, and then summing the sub-combustion emission of all fuels to obtain the fuel combustion emission;

[0093] Specifically, after selecting the target enterprise, select all the fuel types used by the target enterprise, and enter the corresponding fuel consumption of each fuel. Then, the corresponding fuel carbon dioxide emission factor will be selected by default according to the different fuel types. Next, the fuel consumption of each fuel is multiplied by the corresponding fuel carbon dioxide emission factor to obtain the sub-combustion emissions of each fuel, and then the sub-combustion emissions of all fuels are summed to obtain the fuel combustion emissions, that is, the product of the fuel consumption of each fuel and the corresponding fuel carbon dioxide emission factor is calculated and added to obtain the fuel combustion emissions. By selecting all the fuel types used and entering the corresponding fuel consumption, the corresponding fuel carbon dioxide emission factor will be selected by default, that is, the fuel combustion emissions of the target enterprise can be quickly calculated.

[0211] Specifically, for the target enterprise, purchasing or developing forest carbon sinks is an important means to achieve carbon neutrality, and afforestation emissions offset refers to the carbon emissions offset by the target enterprise when planting trees.

[0212] For further information, see Fig. 9 The step of S900, obtaining the number of species and growth years of the trees planted by the target enterprise, and obtaining the net primary productivity per unit area and the forest area of ​​the trees during the growth years, and calculating the emission offset by afforestation based on the net primary productivity per unit area, the forest area and the seventh calculation coefficient, specifically includes:

[0215] S930, respectively calculate the afforestation offset emissions in all growing years, and add them up to obtain the afforestation offset emissions; the afforestation offset emissions are expressed as:

[0216] The unit is tCO 2 e;

[0217] Wherein, q' is the growth age of the trees planted by the target enterprise; q" is the number of species of trees planted by the target enterprise; A q’q” is the forest area of ​​the q'th tree species in the q'th year, in hectares (hm 2 );B q’q”is the net primary productivity per unit area of ​​the q'th tree species in the q'th year, in grams per square meter per year (t / m 2 / year); 0.044=1.63×27.27%, wherein 1.63 is based on the chemical reaction formula of plant photosynthesis, and for every gram of dry matter accumulated by forest vegetation, 1.63 grams of carbon dioxide is fixed, and 27.27% is the percentage of carbon content in carbon dioxide; the seventh calculation coefficient is 0.044.

[0218] Specifically, first, input the number of tree species planted by the target enterprise, the growth years of the trees planted by the target enterprise, the net primary productivity per unit area of ​​the trees in the growth years, and the forest area of ​​the trees in the growth years; then, respectively calculate the product of the net primary productivity per unit area of ​​each tree species in the same year, the forest area of ​​the tree, and the seventh calculation coefficient, and add them up to obtain the afforestation offset sub-emissions of the target enterprise in the same year, that is, the sum of the products of the net primary productivity per unit area of ​​all tree species, the forest area of ​​the tree, and the seventh calculation coefficient in the same year; further, calculate the afforestation offset sub-emissions of the target enterprise in the same year within all years, and then add them up to finally obtain the afforestation offset emissions, so as to efficiently calculate the carbon offset emissions of the target enterprise when afforestation is carried out, that is, the afforestation offset emissions:

[0219] For further information, please refer to Figure 1 , S1000, add the fuel combustion emissions, the electricity use emissions, the heat use emissions, the industrial production emissions, the waste gas and wastewater treatment emissions, the fugitive leakage emissions and the emissions from the use of energy as raw materials, and subtract the offset emissions and the afforestation offset emissions, as well as the target enterprise's purchased carbon offsets, to obtain the target enterprise's carbon emissions.

[0220] Specifically, by adding the fuel combustion emissions, electricity use emissions, heat use emissions, industrial production emissions, waste gas and wastewater treatment emissions, fugitive leakage emissions, and emissions from the use of energy as raw materials calculated in steps, and subtracting the calculated offset emissions and the obtained target enterprise's purchased carbon offset, the target enterprise carbon emissions of a single target enterprise can be quickly and accurately obtained: Q 总 =Q 碳排放 =Q 燃 +Q 电 +Q 热 +Q 过程 +Q 废气废水+ Q 逃逸泄露+Q 原材料使用 -Q 抵 -Q 造林抵消 -Q 外购碳抵消 After further obtaining the target enterprise carbon emissions of multiple identical enterprises in a certain industry, the carbon emissions of the entire industry can be estimated by obtaining the average value, which effectively simplifies the process of calculating the carbon emissions of target enterprises and target industries.

[0221] Among them, the target enterprise's outsourced carbon offset amount is Q 外购碳抵消 It means that the amount of carbon offset purchased by the target enterprise is the carbon credit (carbon offset) purchased by the target enterprise, and the carbon credit includes carbon sink (green carbon, blue carbon, white carbon), carbon emission reduction, carbon capture, etc.; carbon sink refers to the process, activity or mechanism of reducing the concentration of greenhouse gases in the atmosphere by absorbing carbon dioxide in the atmosphere through measures such as afforestation and vegetation restoration; blue carbon is the process, activity and mechanism of using marine activities and marine organisms to absorb carbon dioxide in the atmosphere and fix and store it in the ocean; green carbon is a new type of biofuel, which is a mixture of plant branches and leaves, discarded vegetables and fruits in households, clay and other materials, and then processed through a special process.

[0222] However, when calculating the total carbon emissions of the target enterprise, it is first necessary to clarify the types and types of greenhouse gas emissions. Because different industries emit different types of greenhouse gases and different links, the specific calculation methods are also different.

[0223] For electrolytic aluminum enterprises, the types of greenhouse gases emitted include carbon dioxide, carbon tetrafluoride and carbon hexafluoride; emission types include: fuel combustion emissions, net purchased electricity and heat emissions, production process emissions and emissions from energy used as raw materials. Therefore, the total greenhouse gas emissions of electrolytic aluminum enterprises are equal to the sum of fuel combustion emissions, emissions from electricity and heat consumption, production process emissions and emissions from energy used as raw materials. That is, the greenhouse gas accounting formula for electrolytic aluminum enterprises is: Q 总 =Q 燃 +Q 电 +Q 热 +Q 过程 +Q 原材料使用 .

[0224] For steel production enterprises, according to their production processes, their main greenhouse gas emissions come from fuel combustion emissions, electricity consumption emissions, heat consumption emissions, production process emissions, and carbon sequestration products produced and exported during the production process of steel production enterprises, which can offset part of the carbon emissions. Therefore, the greenhouse gas accounting formula for steel production enterprises is: Q 总 =Q 燃 +Q 电 +Q 热+Q 过程 -Q 抵 , if it is assumed that the steel production enterprise uses 100t of anthracite, 20t of bituminous coal, 30t of general kerosene, and 50t of naphtha; purchases 1000MWh of electricity, exports 100MWh of electricity, purchases 1000GJ of heat, and exports 100GJ of heat; consumes 10t of 90% pure limestone, 10t of 85% pure dolomite, consumes 20t of electrodes, purchases 10t of pig iron, 0t of direct reduced iron, 0t of nickel-iron alloy, 10t of ferrochrome alloy, and 5t of ferromolybdenum alloy; pig iron output: 10t; crude steel output: 10t; methanol output: 5t, then the total input effect diagram for calculating the target enterprise carbon emissions of the steel production enterprise is as follows Fig.10 As shown in the figure, finally, the automatic accounting results of the target carbon emissions of steel production enterprises and the calculation effect diagram of different types of carbon emissions are as follows Fig.11 shown.

The system's built-in formulas and parameters can be used to calculate the carbon emissions of different links in the enterprise, and automatically output comparison charts to help enterprises quickly understand the key links of carbon emissions, so that they can quickly manage and optimize carbon emissions.

[0240] Taking the electrolytic aluminum enterprise carbon as an example, the method of establishing a data processing system for the enterprise carbon emissions is as follows:

[0241] 1. Determine the carbon emission accounting boundary:

[0242] The accounting boundary of the data processing system for corporate carbon emissions is the legal person enterprise or independent accounting unit deemed as a legal person that has greenhouse gas emissions and should be accounted for.
