[0036] Embodiments of the present application are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. 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.

[0037] The carbon emission acquisition method and system of the embodiments of the present application are described below with reference to the accompanying drawings.

[0038] Figure 1 A schematic flow chart of a carbon emission acquisition method provided in an embodiment of the present application.

[0039] To address this problem, the present application provides a carbon emission acquisition method to achieve the acquisition of other types of carbon emissions during the operation and maintenance phase, such as Figure 1 As shown, the carbon emission acquisition method includes the following steps:

[0040] S101, obtaining a carbon emission type set.

[0041] The carbon emission type set includes at least one carbon emission type of fuel combustion, product use, waste disposal, reservoir flooding, soil organic carbon change and indirect carbon emission.

[0042] In some implementations, the life cycle of a hydropower project may include the planning stage, construction stage, operation and maintenance stage, and decommissioning stage. Current research on carbon emissions during the operation and maintenance stage of hydropower projects mostly calculates carbon emissions generated by energy use, ignoring carbon emissions from the production and transportation of energy, materials, and equipment consumed during the operation and maintenance stage.

[0043] It can be understood that obtaining a set of carbon emission types during the operation and maintenance phase of a hydropower project in the embodiment of the present application can analyze the carbon emissions during the operation and maintenance phase in a more comprehensive and detailed manner, thereby improving the comprehensiveness and accuracy of carbon emission acquisition.

[0044] S102, obtaining associated parameters corresponding to each carbon emission type in the carbon emission type set and an emission factor of the carbon emission type over its entire life cycle.

[0045] In some implementations, the associated parameters corresponding to the carbon emission type refer to the parameters related to the carbon emission type, that is, the related parameters of carbon dioxide emissions generated under the carbon emission type; for example, for carbon emissions of fuel combustion type, the corresponding associated parameters may be parameters such as the type of fuel and the total amount of fuel burned; for carbon emissions of product use type, the corresponding associated parameters may be parameters such as the constituent materials of the product, the consumption of the product, the carbon emissions during the use of the product, and the use and consumption of the product that replaces the product; for carbon emissions of waste treatment type, the corresponding associated parameters may be different types of waste (such as sewage, sludge, and wastewater), the emission of gases generated during the treatment of different types of waste, and the use and consumption of gas; The corresponding associated parameters include the diffusion of waste gas, the production of carbon dioxide by gas, and the consumption of other substances in the waste treatment process; for carbon emissions from reservoir flooding, the corresponding associated parameters may be parameters such as reservoir water storage area, the number of days the reservoir is frozen, the number of days the reservoir is not frozen, and the area of ​​reservoir flooding; for carbon emissions from soil organic carbon changes, the corresponding associated parameters may be soil area, soil utilization, soil organic matter content, and carbon emissions from soil organic matter; for indirect carbon emissions, the corresponding associated parameters may be parameters related to indirect carbon dioxide emissions. For example, carbon dioxide will be emitted during the use of electricity and heat, so parameters such as electricity consumption and heat consumption can be used as associated parameters.

[0046] In some implementations, the emission factor of the carbon emission type over its entire life cycle is used to reflect the carbon emissions of each carbon emission type during the operation and maintenance phase. That is, the emission factor can indirectly reflect the emission rate of carbon dioxide. For example, the more carbon dioxide emissions per fixed unit, the larger the corresponding emission factor. Therefore, the carbon emissions of each carbon emission type in the carbon emission type set can be calculated based on the emission factor.

[0047] Optionally, the fixed unit corresponding to the emission factor can be based on the change of carbon emission type, such as units such as per cubic meter, per hectare, per day, per megawatt hour and per kilogram, that is, the carbon dioxide emissions under each fixed unit are used as the corresponding emission factor. For example, the emission factor of the reservoir flooding type can be the carbon dioxide emissions per hectare. In some implementations, for different carbon emission types, the impact of other gases generated under the carbon emission type on carbon emissions can also be fully considered. For example, for the emission factor of the waste treatment type, in addition to the emission factor of carbon dioxide emissions, the emission factors of other gases during waste treatment can also be included to improve the accuracy of obtaining carbon emissions.

[0048] In some implementations, the entire life cycle refers to all links of a product, that is, the complete emission links in the carbon emission type. For example, when analyzing fuel, in addition to considering the combustion of the fuel, it is also necessary to include the carbon emissions generated by the production and transportation of the fuel. Therefore, the carbon emission factor of the entire life cycle of each carbon emission type is obtained to obtain and analyze the carbon emissions, thereby ensuring the accuracy of the carbon emissions.

[0049] S103, determining the carbon emission amount of the corresponding carbon emission type in the carbon emission type set according to the associated parameters and the emission factors.

[0050] It can be understood that the associated parameters are parameters related to carbon dioxide emissions corresponding to the carbon emission type, and the emission factor refers to the emission rate and degree of carbon dioxide by the carbon emission type. Therefore, the carbon emissions of the corresponding carbon emission type can be obtained based on the associated parameters and emission factors.

[0051] Optionally, the product of the associated parameter and the emission factor can be calculated to represent the carbon emissions of the corresponding carbon emission type. A weight factor can also be set to perform a weighted sum calculation on the associated parameter and the emission factor using different weight factors to determine the carbon emissions of the corresponding carbon emission type.

[0052] Obtaining carbon emissions based on associated parameters and emission factors can ensure that all relevant parameters under the current carbon emission type are considered more comprehensively. Obtaining carbon emissions based on actual carbon dioxide emissions and all relevant parameters can make the carbon emissions results more accurate.

[0053] In the embodiment of the present application, various types of carbon emissions during the operation and maintenance stage of a hydroelectric project are analyzed, which solves the current problem of only considering carbon emissions from energy use. Based on the associated parameters and emission factors corresponding to different carbon emission types, carbon emissions from fuel combustion, product use, waste treatment, reservoir flooding, soil organic carbon changes and indirect carbon emissions are obtained, thereby achieving the acquisition of more types of carbon emissions during the operation and maintenance stage of a hydroelectric project and ensuring the accuracy of carbon emissions acquisition.

[0054] Based on the above embodiment, the acquisition of carbon emissions of fuel combustion types is described. Figure 2 This is a flow chart of a method for obtaining carbon emissions of a fuel combustion type provided in an embodiment of the present application. Figure 2 As shown, the method comprises the following steps:

[0055] S201, obtaining the consumption of each type of fuel combustion within the target time and the first emission factor of each type of fuel combustion over the entire life cycle.

[0056] The consumption of each type of fuel combustion is the first associated parameter corresponding to the carbon emission of fuel combustion.

[0057] In some implementations, multiple types of fuels may be burned during the operation and maintenance phase of a hydroelectric project, such as coal, oil, and natural gas, and the combustion of different fuels may emit different amounts of carbon dioxide.

[0058] Optionally, the target time can be set to 1 year, that is, the consumption of each type of fuel combustion within 1 year, that is, the annual consumption of each type of fuel, is obtained, and the consumption of each type of fuel combustion is used as the first associated parameter of the corresponding fuel combustion. It can be understood that the consumption of fuel combustion includes the combustion of fossil fuels from fixed sources such as stoves and the combustion of fossil fuels from mobile sources such as trucks and forklifts.

[0059] Furthermore, the first emission factor of the fuel combustion type over its entire life cycle may be obtained, and the first emission factor includes an upstream emission factor and a downstream emission factor. In some implementations, the upstream emission factor is the carbon dioxide emission factor during fuel production and transportation, and the downstream emission factor is the emission factor when the fuel is actually burned and used, to ensure the analysis of carbon emissions over the entire life cycle of fuel combustion.

[0060] S202: Determine a first emission amount according to a first associated parameter and a first emission factor for combustion of each type of fuel.

[0061] Optionally, the product of the first associated parameter and the first emission factor for each type of fuel combustion may be obtained, and the product may be used as the first emission for each type of fuel combustion, that is, the first emission of carbon dioxide for each type of fuel combustion.

[0062] S203, calculating the sum of the first emission corresponding to each type of fuel combustion as the carbon emission of the fuel combustion type.

[0063] In some implementations, after obtaining the first emission corresponding to each type of fuel combustion, the first emission corresponding to each type of fuel combustion may be summed, and the sum of the first emission of all fuel combustions may be used as the carbon emission of the fuel combustion type.

[0064] Alternatively, the calculation of carbon emissions for fuel combustion type can be:

[0065] E 1 =∑AD 1 ×EF 1

[0066] EF 1 =EF 1上 +EF 1下

[0067] Among them, E 1Carbon emissions from fuel combustion; AD 1 Indicates the annual consumption of each type of fuel, which is the first associated parameter; EF 1 It represents the first emission factor for each type of fuel combustion. 1 The upstream emission factor EF 1上 and downstream emission factor EF 1下 The sum of AD 1 ×EF 1 Indicates the primary emissions from the combustion of each type of fuel.

[0068] In an embodiment of the present application, the carbon emissions of the fuel combustion type are obtained by summing the first emissions of each type of fuel combustion, and the first associated parameters related to each type of fuel combustion, the production stage emission factor (upstream emission factor) and the use stage emission factor (downstream emission factor) are combined to obtain a more comprehensive carbon emissions of fuel combustion, thereby ensuring the accuracy of the carbon emissions of this fuel combustion type.

[0069] Based on the above embodiment, the acquisition of carbon emissions of product usage types is described. Figure 3 This is a flow chart of a method for obtaining carbon emissions of a product usage type provided in an embodiment of the present application. Figure 3 As shown, the method comprises the following steps:

[0070] S301, obtaining the product consumption and the second emission factor of the product within the target time.

[0071] The product usage consumption is the second associated parameter of the product usage type.

[0072] In some implementations, the product usage consumption may include the consumption of fire extinguisher usage, refrigerant filling, and electrical equipment sulfur hexafluoride filling. Optionally, the target time is 1 year, so the second associated parameter may include the annual usage of carbon dioxide fire extinguishers, the annual refrigerant filling, and the electrical equipment sulfur hexafluoride filling.

[0073] Furthermore, the second emission factor used in the product may be an emission factor corresponding to the second associated parameter, that is, an emission factor used in the product including carbon dioxide, refrigerant, and sulfur hexafluoride, respectively. In some implementations, the second associated parameter and the second emission factor may be obtained by querying the historical operation records of the hydropower station or by real-time measurement.

[0074] S302, obtaining the consumption of replacement of spare products and the third emission factor of the spare products throughout their life cycle.

[0075] Among them, the consumption of replacement of the spare product is the third associated parameter of the spare product.

[0076] In some implementations, spare product replacement refers to the replacement of spare parts during the operation and maintenance phase. The consumption of spare product replacement can be the consumption of the spare product within the target time. When the target time is 1 year, the consumption of spare product replacement is the annual consumption of the spare product. That is to say, the third associated parameter of the spare product is the annual consumption of the spare product.

[0077] Furthermore, the mass proportion of each material constituting the spare product can be obtained, that is, the mass proportion of each material in the spare product can be obtained, reflecting whether a certain material is used more in the spare product; considering that the emission factors corresponding to each material are different, the full life cycle emission factor corresponding to each material can be determined, that is, the full life cycle emission factor of the production, transportation and use of each material; according to the full life cycle emission factor of each material and the mass proportion of each material, the third emission factor of the spare product's full life cycle can be determined.

[0078] Optionally, the third emission factor can be obtained by:

[0079] EF 22 =∑W 22i ×EF 22i

[0080] Among them, EF 22 W represents the third emission factor of the spare product throughout its life cycle; 22i represents the mass proportion of the i-th material in the spare product; EF 22i represents the life cycle emission factor of the i-th material in the spare product; ∑W 22i ×EF 22i The mass proportion of each material and its corresponding full life cycle emission factor are multiplied and summed to obtain the third emission factor of the final spare product's full life cycle.

[0081] S303: Determine a first carbon emission amount based on a second correlation parameter and a second emission factor.

[0082] Optionally, the calculation of the first carbon emission amount may be:

[0083] E 21 =∑AD 21 ×EF 21

[0084] Among them, E 21 Indicates the first carbon emission; AD 21 Indicates the product consumption (annual usage of carbon dioxide fire extinguishers, annual refrigerant filling, annual sulfur hexafluoride filling of electrical equipment), which is the second associated parameter; EF 21Represents the emission factor of carbon dioxide, refrigerant, and sulfur hexafluoride, which is the second emission factor; ∑AD 21 ×EF 21 That is, multiply the usage of carbon dioxide fire extinguishers and the carbon dioxide emission factor, the annual refrigerant charging volume and the refrigerant emission factor, the annual sulfur hexafluoride charging volume of electrical equipment and the sulfur hexafluoride emission factor respectively and then sum them up to obtain the first carbon emission of the final product.

[0085] S304: Determine a second carbon emission amount based on the third correlation parameter and the third emission factor.

[0086] Optionally, the second carbon emission amount may be calculated as:

[0087] E 22 =∑AD 22 ×EF 22

[0088] Among them, E 22 Indicates the second carbon emission; AD 22 Indicates the annual consumption of spare products, which is the third associated parameter; EF 22 Represents the third emission factor of the spare product's entire life cycle; ∑AD 22 ×EF 22 It represents the annual consumption of spare products multiplied by the corresponding third emission factor and then summed.

[0089] S305, calculating the sum of the first carbon emission and the second carbon emission as the carbon emission of the product usage type.

[0090] Further, after determining the first carbon emission of product use and the second carbon emission of spare part replacement in the product use type, the sum of the first carbon emission and the second carbon emission is used as the carbon emission of the product use type.

[0091] In some implementations, the carbon emissions of a product usage type are calculated as:

[0092] E 2 =E 21 +E 22

[0093] Among them, E 2 Indicates the carbon emissions of the product usage type.

[0094] In an embodiment of the present application, the carbon emissions of product usage types are obtained, and the product usage types of product consumption and spare parts usage are analyzed separately to obtain the corresponding first carbon emissions and second carbon emissions, thereby determining the carbon emissions of the product usage type, and performing specific quantitative calculations on the carbon emissions of the product usage type to improve the accuracy of the calculation of the carbon emissions of the product usage type.

[0095] Based on the above embodiment, the acquisition of carbon emissions of waste treatment types is described. Figure 4 A schematic diagram of a method for obtaining carbon emissions from a type of waste treatment provided in an embodiment of the present application. Figure 4 As shown, the method comprises the following steps:

[0096] S401, obtaining the first gas emission and the first gas global increment of domestic sewage treatment, and the second gas emission and the second gas global increment of wastewater treatment within a target time.

[0097] Optionally, waste treatment may include domestic sewage treatment and wastewater treatment; a first gas, methane, may be produced during sewage treatment, and a second gas, nitrous oxide, may be produced during wastewater treatment. Therefore, the first gas and the second gas are analyzed separately to determine the carbon emissions during waste treatment.

[0098] In some implementations, the target time may be 1 year, so the first gas emissions from domestic sewage treatment within 1 year, that is, methane emissions, are obtained, and the second gas emissions from wastewater treatment within 1 year, that is, nitrous oxide emissions, are obtained.

[0099] It can be understood that the global increase of the first gas is the global warming potential of methane, and the global increase of the second gas is the global warming potential of nitrous oxide. The global increase of the first gas and the global increase of the second gas can be directly obtained based on existing data.

[0100] Further, the emission of the first gas and the emission of the second gas are obtained. Optionally, a fourth correlation parameter of the first gas and a fourth emission factor of the first gas may be obtained, and the emission of the first gas may be determined according to the fourth correlation parameter and the fourth emission factor; a fifth correlation parameter of the second gas and a fifth emission factor of the second gas may be obtained, and the emission of the second gas may be determined according to the fifth correlation parameter and the fifth emission factor.

[0101] Optionally, the first gas emission amount may be obtained by:

[0102] E 31 =((TOW*EF 31 )-R)

[0103] Among them, E 31represents the emission of the first gas; TOW represents the organic matter content in domestic sewage (kg BOD / year); R represents the recovery of the first gas, that is, the recovery of methane (kg methane / year); EF 31 It represents the methane carbon emission factor, that is, the fourth emission factor (kg methane / kg BOD); wherein, the first gas recovery amount R and the organic matter content TOW in domestic sewage are the fourth associated parameters of the first gas.

[0104] Furthermore, the emission factor of the first gas may be:

[0105] EF 31 =B 0 *MCF

[0106] Among them, B 0 represents the maximum methane production capacity; MCF represents the methane correction factor.

[0107] In some implementations, the fourth associated parameter of the first gas may also include a maximum methane production capacity B 0 and methane correction factor MCF.

[0108] Optionally, the second gas emission amount may be obtained by:

[0109] E 32 =N*EF 32 *44 / 28

[0110] Among them, E 32 Indicates the emission of the second gas; N indicates the nitrogen content in the sewage (kg nitrogen / year), which is the fifth associated parameter of the second gas; EF 32 represents the nitrous oxide emission factor, which is the fifth emission factor (kg nitrogen-nitrous oxide / kg nitrogen); 44 / 28 is the constant coefficient used to convert kg nitrogen-nitrous oxide to kg nitrous oxide.

[0111] Furthermore, the fifth associated parameter, that is, the method for obtaining the nitrogen content in the sewage is:

[0112] N=(P*P r *F NRP *F NON-CON *F IND-COM )-N s

[0113] Where P represents the number of people used in the operation and maintenance phase; P r represents the annual per capita protein consumption (kg / person / year), F NRP Indicates the nitrogen content in protein (kg nitrogen / kg protein), F NON-CON represents the emission factor of non-consumable proteins in wastewater, F IND-COMrepresents the protein emission factor for industry and commerce, N s Expresses nitrogen removed with sludge (kg N / year).

[0114] It can be understood that the indicators such as consumption, population, nitrogen content and emission factor involved in the calculation process of the above-mentioned fifth associated parameter can be obtained based on existing information queries; thereby, the first gas emissions and the second gas emissions can be obtained based on the above-mentioned method for obtaining the first gas emissions and the method for obtaining the second gas emissions.

[0115] S402: Determine a third carbon emission according to the first gas emission and the global increment of the first gas.

[0116] Optionally, the product of the first gas emission and the first gas global increment can be obtained as the third carbon emission. That is, the third carbon emission is E 31 *GWP CH4 , where GWP CH4 It represents the global increase of the first gas, that is, the global warming potential of methane.

[0117] S403: Determine the fourth carbon emission according to the second gas emission and the global increment of the second gas.

[0118] Optionally, the product of the second gas emission and the second gas global increment can be obtained as the fourth carbon emission. That is, the second carbon emission is E 32 *GWP N2O , where GWP N2O represents the global increase in the second gas, namely the global warming potential of nitrous oxide.

[0119] S404, calculating the sum of the third carbon emission amount and the fourth carbon emission amount as the carbon emission amount of the waste treatment type.

[0120] After the third carbon emission amount and the fourth carbon emission amount are determined, a sum of the third carbon emission amount and the fourth carbon emission amount may be calculated as the carbon emission amount of the waste treatment type.

[0121] Optionally, the carbon emissions for waste treatment type can be:

[0122] E 3 =E 31 *GWP CH4 +E 32 *GWP N2O

[0123] Among them, E 3 Represents the carbon emissions of the waste treatment type.

[0124] In the embodiment of the present application, the carbon emissions of the waste treatment type are obtained through two aspects: domestic sewage treatment and wastewater treatment. The carbon emissions are calculated by comprehensively analyzing the first gas in domestic sewage treatment and the second gas in wastewater treatment as well as other relevant characteristic indicators to ensure a comprehensive analysis of the carbon emissions and reliable calculation of the carbon emissions.

[0125] Based on the above embodiment, the acquisition of carbon emissions of reservoir flooding type is described. Figure 5 This is a flow chart of a method for obtaining carbon emissions of a reservoir flooding type provided in an embodiment of the present application. Figure 5 As shown, the method comprises the following steps:

[0126] S501, obtaining the number of days when the reservoir is not covered with ice, the reservoir storage area and the sixth emission factor of the reservoir diffusion within the target time.

[0127] Among them, the sixth associated parameter of the reservoir flooding type includes: at least one of the number of days when the reservoir is not covered with ice within the target time and the water storage area of ​​the reservoir.

[0128] In some implementations, the target time may be 1 year, that is, obtaining the number of days in which the reservoir is not covered with ice within 1 year.

[0129] In some implementations, the proportion of reservoir flooding in recent years to the total water storage area can also be obtained as a proportion parameter, for example, the average proportion of reservoir flooding in the past 10 years to the total water storage area is obtained as a proportion parameter, and the total proportion of reservoir flooding in the past 10 years to the total water storage area can also be obtained as a proportion parameter; the carbon emissions of reservoir flooding types are obtained based on the proportion parameters.

[0130] S502, calculating the multiplication result of the sixth correlation parameter and the sixth emission factor, and determining the carbon emission of the reservoir flooding type according to the multiplication result.

[0131] Alternatively, the carbon emissions for reservoir flooding type can be:

[0132] E 4 =P ice ×EF 4 ×A×f

[0133] Among them, E 4 represents the carbon emission of reservoir flooding type; P ice represents the number of days in a year when the reservoir is not covered by ice; A represents the reservoir storage area (hectares); P ice and A are the sixth associated parameters of reservoir flooding type; EF 4 It represents the average daily diffusion of carbon dioxide in the reservoir within one year (kg carbon dioxide / hectare·day), which is also the sixth emission factor; f represents the proportional parameter.

[0134] In the embodiment of the present application, the carbon emissions of the reservoir flooding type are obtained by obtaining the total water storage area occupied by reservoir flooding in recent years as a proportion parameter, combining the sixth associated parameter (the number of days without ice cover on the reservoir and the water storage area of ​​the reservoir) and the sixth emission factor (the average daily diffusion of carbon dioxide), fully considering the status of the reservoir within one year, and improving the accuracy of carbon emissions.

[0135] Based on the above embodiment, the acquisition of carbon emission of soil organic carbon change type is described. Figure 6 A flow chart of a method for obtaining carbon emissions of soil organic carbon change type provided in an embodiment of the present application. Figure 6 As shown, the method comprises the following steps:

[0136] S601, obtaining the area of ​​soil utilization type change and the net sequestration rate of soil organic carbon within the target time.

[0137] Among them, the area of ​​soil utilization type change is the seventh associated parameter of soil organic carbon change type, and the net sequestration rate of soil organic carbon when soil utilization type changes is the seventh emission factor of soil organic carbon change type.

[0138] In some implementations, soil use type change refers to a change in soil use, such as a change from soil use type j to soil use type k. When the soil use type changes, it will affect carbon dioxide emissions, so the area of ​​the soil use type change is obtained as the seventh associated parameter.

[0139] In some implementations, the net soil organic carbon sequestration rate when the soil use type changes refers to the amount of organic carbon per hectare of land that is converted from soil use type j to soil use type k within one year, reflecting the carbon dioxide contained in the land. That is, the unit of the net soil organic carbon sequestration rate is (tons of carbon / (hectare·year)).

[0140] S602, calculating the product of the seventh correlation parameter and the seventh emission factor, and determining the carbon emission of the soil organic carbon change type according to the product.

[0141] Alternatively, the calculation of carbon emissions of soil organic carbon change type can be:

[0142] E 5 =∑(A j-k *SOC rate *44 / 12)

[0143] Among them, E 5 Indicates the carbon emission of soil organic carbon change type; A j-kIndicates the soil area that changes from soil use type j to soil use type k, which is the seventh associated parameter of soil organic carbon change type; SOC rate It represents the net sequestration rate of soil organic carbon when soil use type j is converted to soil use type k, which is the seventh emission factor of soil organic carbon change type; 44 / 12 is a constant coefficient used to convert the mass of carbon into the mass of carbon dioxide.

[0144] In an embodiment of the present application, the change area of ​​soil utilization type and the net sequestration rate of soil organic carbon when the soil utilization type changes are obtained as the seventh associated parameter and the seventh emission factor, fully considering the carbon emissions when the soil changes, and obtaining the carbon emissions under the soil organic carbon change type is more comprehensive and accurate, and the calculation efficiency is higher.

[0145] Based on the above embodiment, the acquisition of carbon emissions of indirect carbon emissions is described. Figure 7 The following is a flow chart of a method for obtaining carbon emissions of an indirect carbon emission type provided in an embodiment of the present application. Figure 7 As shown, the method comprises the following steps:

[0146] S701, obtaining electricity consumption, heat consumption, electricity emission factor and heat emission factor within a target time.

[0147] In some implementations, the target time may be 1 year, that is, the power consumption and heat consumption within 1 year are obtained. It is understandable that the power consumption refers to the carbon dioxide emissions of purchased power, and the heat consumption refers to the carbon dioxide emissions of purchased heat.

[0148] Optionally, the electricity emission factor may be the carbon emission factor (tons / MWh) of electricity consumption in the region where the hydropower project is located, and the heat emission factor may be the carbon emission factor (tons / GJ) of heat consumption in the region where the hydropower project is located.

[0149] In some implementations, the electricity consumption and heat consumption can be obtained by querying the purchase records of the hydropower project. The electricity emission factor and the heat emission factor can be known when the electricity and heat are purchased.

[0150] S702, determining the fifth carbon emission according to the power consumption and the power consumption factor.

[0151] Optionally, the fifth carbon emission amount may be calculated as:

[0152] E 61 =AD 61 *EF 61

[0153] Among them, E 61Indicates the fifth carbon emission; AD 61 Indicates electricity consumption (MWh); EF 61 represents the electricity emission factor.

[0154] S703, determining the sixth carbon emission according to the heat consumption and the heat emission factor.

[0155] Optionally, the calculation of the sixth carbon emission amount may be:

[0156] E 62 =AD 62 *EF 62

[0157] Among them, E 62 Indicates the sixth carbon emission; AD 62 Indicates heat consumption (GJ); EF 62 represents the heat emission factor.

[0158] S704, calculating the sum of the fifth carbon emission amount and the sixth carbon emission amount as the carbon emission amount of the indirect carbon emission type.

[0159] It can be understood that the carbon emissions of the indirect carbon emissions type are the sum of the fifth carbon emissions and the sixth carbon emissions, that is, the carbon emissions of the indirect carbon emissions type E 6 =E 61 +E 62 .

[0160] In an embodiment of the present application, by querying and obtaining the situation of purchased electricity and purchased heat in the hydropower project, the indirect carbon emissions of purchased electricity and purchased heat are obtained, thereby obtaining the carbon emissions of the indirect carbon emission type, which provides a relatively simple basis for the calculation of the carbon emissions of the indirect carbon emission type, and the accuracy of obtaining the carbon emissions of the indirect carbon emission type is relatively high.

[0204] S822, obtaining the service life of the hydropower station and the total power generation of the hydropower station.

[0205] In some implementations, the working life of a hydropower station is the life cycle of the hydropower station (years), and the total power generation of the hydropower station is the total power generation of the hydropower station in its entire life cycle (MWh).

[0208] Furthermore, based on the total carbon emissions, total power generation and working years, the carbon emissions per kilowatt-hour of the hydropower station are determined as follows:

[0209] E 7 =[∑a*(E 1 +E 2 +E 3 +E 4 +E 5 +E 6 )] / EG
