Summary of the invention

[0004] The purpose of the present invention is to address the problem that the prior art does not consider the mutual influence of different carbon emission sources, resulting in difficulties in tracing and supervising carbon emission data; a carbon flow calculation method based on the electricity-carbon interaction relationship is proposed, by setting the corresponding carbon emission factors and sorting the nodes through the electricity-carbon topology structure established based on the distribution network topology structure, then calculating the carbon emissions according to the real-time carbon emission data, the carbon emission factors and the nodes that have completed the hierarchical sorting, and determining the flow direction of the carbon emissions based on the electric quantity in the real-time carbon emission data, finally, establishing a real-time electricity-carbon topology map based on the carbon emissions, the flow direction, the real-time carbon emission data and the electricity-carbon topology structure, and using the real-time electricity-carbon topology map to visualize the carbon emissions, carbon emission sources and the flow direction of the carbon emissions, and then observing the corresponding carbon flow path and other information, which not only refines the carbon flow data, but also can reflect the actual carbon emission situation in real time, and can also achieve accurate carbon emission data traceability and supervision based on the carbon flow path and the flow direction of the carbon emissions.

[0005] In a first aspect, a technical solution provided in an embodiment of the present invention is a carbon flow calculation method based on an electric-carbon interaction relationship, comprising the following steps: S1. Establish an electric-carbon topology structure based on the distribution network topology structure, and set a carbon emission factor according to the electric-carbon topology structure; S2. Collecting real-time carbon emission data based on the electric-carbon topological structure, and hierarchically sorting the nodes in the electric-carbon topological structure to obtain a set of row-level nodes; S3, calculating the carbon emission amount according to the real-time carbon emission data, the carbon emission factor and the row-level node set, and determining the flow direction corresponding to the carbon emission amount based on the power in the real-time carbon emission data; S4. Establish a real-time electric-carbon topology map based on the carbon emissions, flow direction, real-time carbon emission data and electric-carbon topology structure.

[0006] In this scheme, an electric-carbon topological structure is established based on the distribution network topological structure, the corresponding relationship between the current and the carbon flow in the distribution network is obtained, the carbon emission factor is set according to the electric-carbon topological structure, real-time carbon emission data is collected based on the electric-carbon topological structure, and the nodes in the electric-carbon topological structure are hierarchically sorted to obtain a hierarchical node set, the priorities of different nodes are clarified, and the hierarchy and logic of different nodes and the carbon data corresponding to the nodes are enhanced. Then, the carbon emissions are calculated according to the real-time carbon emission data, the carbon emission factors and the hierarchical node set, the carbon emissions of the nodes are quantified according to the hierarchy and logic of the nodes, the flow direction of the corresponding carbon emissions is determined based on the electricity in the real-time carbon emission data, the carbon flow, that is, the flow direction of the carbon emissions, is clarified, and the hierarchy and logic corresponding to the carbon emissions are and flow direction can also be combined with the electric-carbon topological structure to obtain the corresponding carbon flow path. Finally, a real-time electric-carbon topological map is established based on the carbon emissions, flow direction, real-time carbon emission data and the electric-carbon topological structure. The real-time electric-carbon topological map is used to visualize the carbon emissions, carbon emission sources and the flow direction of carbon emissions, and then the corresponding carbon flow path and other information can be observed. It not only refines the carbon flow data, but also can reflect the actual carbon emissions in real time, and can also realize accurate carbon emission data traceability and supervision according to the carbon flow path and the flow direction of carbon emissions. When the data traceability is completed, the position of the abnormal data in the distribution network topology structure corresponding to the abnormal data can be accurately judged based on the position of the abnormal data in the electric-carbon topological structure combined with the correspondence between current and carbon flow, so as to realize accurate positioning of abnormal carbon emissions.

[0007] Preferably, in S1, the specific process of establishing the electric-carbon topology structure based on the distribution network topology structure and setting the carbon emission factor according to the electric-carbon topology structure is: S111, extracting the physical connection relationship between electrical equipment, nodes and sites based on the topological structure of the distribution network, and obtaining the physical information of the electrical equipment, nodes and sites; S112, establishing an electric-carbon topology structure according to the physical connection relationship and the physical information, and dividing the nodes of the electric-carbon topology structure into active monitoring nodes and passive monitoring nodes based on the carbon emission monitoring equipment in the electric-carbon topology structure; S113. Determine the carbon emission factor of the node based on the active monitoring nodes and the passive monitoring nodes in combination with the carbon emission factor assignment rule.

[0008] In this solution, an electric-carbon topology structure is established based on the physical connection relationship and physical information, and the physical connection relationship of the distribution network is combined with carbon emission monitoring. The electrical data and electrical structure corresponding to carbon emissions can be reflected while achieving carbon regulation. The carbon emission monitoring equipment in the electric-carbon topology structure divides the nodes of the electric-carbon topology structure into active monitoring nodes and passive monitoring nodes, and the configuration of regulatory resources can be adjusted according to the characteristics of the nodes and the needs of carbon regulation.

[0009] Preferably, in S113, the specific process of determining the node carbon emission factor based on the active monitoring node and the passive monitoring node combined with the carbon emission factor assignment rule is: When the node is a passive monitoring node, the historical carbon emission factor is obtained based on the physical information of the electrical equipment, node and site corresponding to the node, and the carbon emission factor of the node is obtained by averaging; When a node is an active monitoring node, the electric carbon calculation device corresponding to the node automatically obtains the carbon emission factor of the node.

[0010] In this scheme, when the node is a passive monitoring node, the historical carbon emission factors under the same physical conditions or different physical conditions can be averaged to obtain an accurate and stable carbon emission factor that reflects the carbon emission level of the passive monitoring node in the corresponding time period. When the node is an active monitoring node, the carbon emission factor of the node is automatically obtained through the corresponding electric carbon calculation device, which can ensure the real-time and accuracy of the corresponding carbon emission factor of the active monitoring node.

[0011] Preferably, in S2, the specific process of collecting real-time carbon emission data based on the electric-carbon topological structure is: Acquire power message data based on the electric-carbon topology structure and a preset data collection cycle, and parse the power message data according to the power communication protocol to obtain real-time carbon emission data; Synchronously, the real-time carbon emission data is stored in a corresponding memory.

[0012] In this solution, power message data is periodically acquired and parsed to obtain real-time carbon emission data, which effectively ensures the real-time nature of the real-time carbon emission data and can ensure the real-time nature of the carbon supervision process based on the real-time carbon emission data.

[0013] Preferably, in S2, the specific process of hierarchically sorting the nodes in the electric-carbon topological structure to obtain the ranked node set is: S211, based on the nodes in the electric-carbon topology structure and the physical information of the sites, the nodes in the electric-carbon topology structure are divided into power generation side nodes, power transformation side nodes and power consumption side nodes; S212, setting the power generation side node as the first-level node based on the physical connection relationship between the electrical equipment, nodes and sites in the electric carbon topology structure, and setting the substation side node as the second-level node based on the physical connection relationship between the electrical equipment, nodes and sites in the electric carbon topology structure; Synchronously, the power consumption side nodes are set as the third-level nodes based on the physical connection relationship between the electrical equipment, nodes and sites in the electric-carbon topology structure.

[0014] In this scheme, the nodes are divided into power generation side nodes, substation side nodes and power consumption side nodes. In fact, the nodes are divided according to the main flow direction of electric energy in the distribution network, and then the nodes can be sorted according to the main flow direction of current. However, there are different levels of power generation equipment, substation equipment and power consumption equipment in the distribution network, so the divided nodes are graded to further clarify the flow path of the carbon flow generated by electric energy in the electric-carbon topological structure.

[0015] Preferably, in S3, the specific process of calculating the carbon emissions according to the real-time carbon emission data, the carbon emission factor and the row-level node set is: S311, extracting corresponding real-time carbon emission data based on the ranking relationship of the nodes in the ranking node set, and extracting carbon emission factors according to the nodes corresponding to the real-time carbon emission data; S312: Calculate the carbon emission of the corresponding node according to the real-time carbon emission data and the carbon emission factor, and sort the carbon emission based on the node sorting relationship.

[0016] In this solution, the carbon emissions of the corresponding nodes are calculated based on the real-time carbon emission data and the carbon emission factors, and the carbon emissions are sorted based on the node sorting relationship. The quantified carbon emissions can be matched with the carbon flow path in the electric-carbon topology structure, thereby refining the supervision of carbon emissions.

[0017] Preferably, in S311, when extracting the carbon emission factor according to the corresponding node of the real-time carbon emission data, it is also necessary to obtain the corresponding parameters according to the sorting relationship of the nodes, specifically: When the node is a second-level node in the row-level node set corresponding to the substation-side node, the carbon emission factor and node type of the node directly above the node are obtained based on the electric-carbon topological structure; When the node is a third-level node corresponding to the power-consuming side node in the row-level node set, the carbon emission factor and node type of the direct superior node corresponding to the node are obtained based on the electric-carbon topological structure.

[0018] Preferably, in S312, the calculation formula of carbon emissions is specifically: C = K × Q; In the formula, C is carbon emissions, K is the carbon emission factor, and Q is electricity.

[0019] Preferably, in S3, the specific process of determining the corresponding carbon emission flow direction based on the power in the real-time carbon emission data is: S321, matching the electric quantity with the node based on the corresponding relationship between the real-time carbon emission data and the node, and dividing the electric quantity corresponding to the node into forward electric quantity and reverse electric quantity according to the direction of electric energy flow corresponding to the electric quantity; S322, accumulating and calculating the forward power and the reverse power to obtain the node accumulated power, and determining the flow direction of the carbon emission of the corresponding node according to the node accumulated power and the preset carbon emission direction.

[0020] In this scheme, in view of the fact that the inflow and outflow of electricity at each node are different, that is, the main flow direction of electric energy in the corresponding distribution network is formed by the convergence of multiple small currents, resulting in certain differences in the flow direction of carbon emissions generated by electric energy at each node. Therefore, the electricity corresponding to the node is divided into forward electricity and reverse electricity according to the flow direction of electric energy corresponding to multiple or single electricity quantities at the node, and the flow direction of the electricity relative to the node is obtained. The flow direction of carbon emissions at the node is calculated based on the flow direction of the electricity relative to the node, so that the difference in the flow direction of carbon emissions corresponding to each node can be made apparent.

[0021] Preferably, in S4, the specific process of establishing a real-time electric-carbon topology map based on the carbon emissions, flow direction, real-time carbon emission data and electric-carbon topology structure is: S411, using the sites in the electric-carbon topological structure as unit entities and combining the electric-carbon topological structure to establish an electric-carbon topological map; S412, filling the real-time carbon emission data into the corresponding nodes based on the corresponding relationship between the real-time carbon emission data and the nodes, and marking the flow direction between the nodes; Simultaneously, the carbon emissions and the carbon emission factors are filled into the corresponding sites based on the corresponding relationship between the carbon emissions and the nodes and the corresponding relationship between the carbon emissions and the carbon emission factors.

[0022] The present invention has at least the following substantial effects: The present application establishes an electric-carbon topology structure based on the distribution network topology structure, obtains the correspondence between the current and the carbon flow in the distribution network, sets the carbon emission factor according to the electric-carbon topology structure, collects real-time carbon emission data based on the electric-carbon topology structure, and hierarchically sorts the nodes in the electric-carbon topology structure to obtain a row node set, clarifies the priorities of different nodes, enhances the hierarchy and logic of different nodes and the carbon data corresponding to the nodes, then calculates the carbon emissions according to the real-time carbon emission data, the carbon emission factor and the row node set, quantifies the carbon emissions of the nodes according to the hierarchy and logic of the nodes, determines the flow direction of the corresponding carbon emissions based on the amount of electricity in the real-time carbon emission data, clarifies the carbon flow, that is, the flow direction of the carbon emissions, and the hierarchy, logic and The flow direction can also be combined with the electric-carbon topological structure to obtain the corresponding carbon flow path. Finally, a real-time electric-carbon topological map is established based on the carbon emissions, flow direction, real-time carbon emission data and the electric-carbon topological structure. The real-time electric-carbon topological map is used to visualize the carbon emissions, carbon emission sources and the flow direction of carbon emissions, and then the corresponding carbon flow path and other information can be observed. It not only refines the carbon flow data, but also can reflect the actual carbon emissions in real time, and can also realize accurate carbon emission data traceability and supervision according to the carbon flow path and the flow direction of carbon emissions. When the data traceability is completed, the position of the abnormal data in the distribution network topology structure corresponding to the abnormal data can be accurately judged based on the position of the abnormal data in the electric-carbon topological structure combined with the correspondence between current and carbon flow, so as to realize accurate positioning of abnormal carbon emissions.

[0025] In order to make the objectives, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific implementation method described herein is only an optimal embodiment of the present invention, which is only used to explain the present invention and does not limit the scope of protection of the present invention. All other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0026] Before discussing the exemplary embodiments in more detail, it should be mentioned that some exemplary embodiments are described as processes or methods depicted as flow charts. Although the flow charts describe the operations (or steps) as sequential processes, many of the operations (or steps) therein can be implemented in parallel, concurrently, or simultaneously. In addition, the order of the operations can be rearranged. The process can be terminated when its operation is completed, but can also have additional steps not included in the drawings; the process can correspond to a method, function, procedure, subroutine, subprogram, etc.

[0027] Embodiment 1: like Figure 1 As shown, this embodiment provides a carbon flow calculation method based on the electric-carbon interaction relationship, comprising the following steps: S1. Establish an electric-carbon topology structure based on the distribution network topology structure, and set a carbon emission factor according to the electric-carbon topology structure; S111, extracting the physical connection relationship between electrical equipment, nodes and sites based on the topological structure of the distribution network, and obtaining the physical information of the electrical equipment, nodes and sites; S112, establishing an electric-carbon topology structure according to the physical connection relationship and the physical information, and dividing the nodes of the electric-carbon topology structure into active monitoring nodes and passive monitoring nodes based on the carbon emission monitoring equipment in the electric-carbon topology structure; S113, determining the carbon emission factor of the node based on the active monitoring node and the passive monitoring node combined with the carbon emission factor assignment rule; when the node is a passive monitoring node, obtaining the historical carbon emission factor based on the physical information of the electrical equipment, node and site corresponding to the node, and averaging the carbon emission factor of the node; When a node is an active monitoring node, the electric carbon calculation device corresponding to the node automatically obtains the carbon emission factor of the node.

[0028] In this embodiment, the distribution network is configured or additionally provided with all carbon emission monitoring related field equipment such as carbon dioxide monitoring terminals and electric carbon meters. Therefore, when the corresponding system equipment of this embodiment is installed on site, it is necessary to investigate and confirm the physical connection relationship between the power plant, substation, and electricity users, and obtain physical information such as sites, nodes, monitoring points, station-station associations, station-node subordination, and corresponding electrical equipment based on the distribution network topology structure. According to the physical connection relationship and physical information, the initial physical topology of the electric carbon relationship, that is, the electric carbon topology structure, is established. At the same time, taking the site in the electric carbon topology structure as the unit, an electric carbon meter that supports the electric carbon calculation function is selected from the site equipment to set the electric carbon calculation device for each site, and set the corresponding initial input and output directions of the electric carbon calculation device based on the on-site installation situation. However, some sites do not support the setting of electric carbon calculation equipment, so Units that support the setting of electric carbon calculation devices, such as sites that are marked as active monitoring nodes, will be marked as passive monitoring nodes if they do not support the setting of electric carbon calculation devices. In addition, nodes and monitoring points are marked using the same logic as sites. Active monitoring nodes correspond to electric carbon calculation devices, so the electric carbon calculation devices in the active monitoring nodes can automatically calculate carbon emission factors and other information based on real-time monitored carbon data. Passive monitoring nodes do not support the setting of electric carbon calculation devices, so they do not have the ability to automatically calculate. Based on the physical information of the electrical equipment, nodes and sites corresponding to the nodes, the corresponding historical carbon emission factors can be obtained through offline queries, traditional ticket statistics and other methods to average and determine the carbon emission factor of the node, or the national average method can be used to directly assign the carbon emission factor of the node using multiple identical or similar node data.

[0029] S2. Collect real-time carbon emission data based on the electric-carbon topological structure, and sort the nodes in the electric-carbon topological structure to obtain a set of ranked nodes.

[0030] In one embodiment, the specific process of collecting real-time carbon emission data based on the electric carbon topology structure is: Acquire power message data based on the electric-carbon topology structure and a preset data collection cycle, and parse the power message data according to the power communication protocol to obtain real-time carbon emission data; Synchronously, the real-time carbon emission data is stored in a corresponding memory.

[0031] In this embodiment, in view of the presence of carbon dioxide monitoring terminals, electric carbon meters and other equipment in the electric carbon topology structure, real-time carbon emission data can be directly collected based on the equipment, and corresponding electricity data also needs to be collected as a component of the real-time carbon emission data. However, the original information of the real-time carbon emission data is a string of messages, which needs to be decoded according to the standard decoding of the power communication protocol, and the data in the message format is converted into data in a commonly used format. The data collection period can be set to 5 minutes according to the rate at which the carbon flow changes due to the flow of electric energy in the distribution network.

[0032] In one embodiment, the specific process of hierarchically sorting the nodes in the electric carbon topological structure to obtain a ranked node set is: S211, based on the nodes in the electric-carbon topology structure and the physical information of the sites, the nodes in the electric-carbon topology structure are divided into power generation side nodes, power transformation side nodes and power consumption side nodes; S212, setting the power generation side node as the first-level node based on the physical connection relationship between the electrical equipment, nodes and sites in the electric carbon topology structure, and setting the substation side node as the second-level node based on the physical connection relationship between the electrical equipment, nodes and sites in the electric carbon topology structure; Synchronously, the power consumption side nodes are set as the third-level nodes based on the physical connection relationship between the electrical equipment, nodes and sites in the electric carbon topology structure.

[0033] S3. Calculate the carbon emission amount according to the real-time carbon emission data, the carbon emission factor and the row-level node set, and determine the flow direction corresponding to the carbon emission amount based on the power in the real-time carbon emission data.

[0034] In one embodiment, the specific process of calculating the carbon emissions according to the real-time carbon emission data, the carbon emission factor and the row-level node set is: S311, extracting corresponding real-time carbon emission data based on the ranking relationship of the nodes in the ranking node set, and extracting carbon emission factors according to the nodes corresponding to the real-time carbon emission data; In one embodiment, when extracting the carbon emission factor according to the corresponding node of the real-time carbon emission data, it is also necessary to obtain the corresponding parameters according to the sorting relationship of the nodes, specifically: When the node is a second-level node in the row-level node set corresponding to the substation-side node, the carbon emission factor and node type of the node directly above the node are obtained based on the electric-carbon topological structure; When the node is a third-level node corresponding to the power-consuming side node in the row-level node set, the carbon emission factor and node type of the direct superior node corresponding to the node are obtained based on the electric-carbon topological structure.

[0035] In this embodiment, although the power generation side nodes, substation side nodes and power consumption side nodes in the electric-carbon topology structure nodes have been set as first-level nodes, second-level nodes and third-level nodes according to the corresponding settings of power generation, substation and power consumption, the substation side nodes corresponding to the second-level nodes also include nodes such as the power generation side nodes corresponding to the substation, and the power consumption side nodes corresponding to the third-level nodes also include nodes such as the power generation side nodes corresponding to the self-built power sources of the electricity users. In addition, the power generation side nodes and other nodes have a certain impact on the carbon flow path in the electric-carbon topology structure, which will increase the branches of the carbon flow path. At the same time, the carbon emission factors of the power generation side nodes and other nodes, the mutual correlation relationship and other attribute information will increase the overall complexity of the carbon flow in the electric-carbon topology structure. Therefore, when extracting real-time carbon emission data, it is necessary to extract the carbon emission factor and node type of the corresponding upper node as parameters and add them to the subsequent carbon emission calculation process.

[0036] S312, calculating the carbon emission of the corresponding node according to the real-time carbon emission data and the carbon emission factor, and sorting the carbon emission based on the node sorting relationship; In one embodiment, the carbon emission calculation formula is specifically: C = K × Q; In the formula, C is carbon emissions, K is the carbon emission factor, and Q is electricity.

[0037] In this embodiment, the carbon emissions of each node are calculated in sequence according to the order of the nodes in the row node set. When the node is a first-level node, that is, a power generation side node, the carbon emissions obtained from the carbon dioxide monitoring terminal, that is, the carbon emissions directly obtained from the corresponding power generation side node in the real-time carbon emission data, can be sent to the electric carbon calculation device corresponding to the node. The electric carbon calculation device automatically calculates the carbon emission factor and other information based on the monitored carbon emission data. For the passive monitoring nodes in the first-level nodes, it is necessary to calculate the corresponding electricity and other information based on the set carbon emission factor, carbon emission formula and carbon emissions. The carbon emission formula is the calculation formula for carbon emissions. When the node is a second-level node, that is, a substation side node, the carbon emissions The calculation process is similar to that of the first-level node, both of which are automatically calculated using the electric carbon calculation equipment or actively calculated using the carbon emission formula. The difference is that when the second-level node calculates carbon emissions, it needs to obtain the parameters of the upper-level node, including at least the node type, carbon emission factor, forward power and reverse power, and then establish a connection with the upper-level node to support the subsequent determination of the direction of carbon emissions and the determination of the carbon flow path; when the node is a third-level node, that is, a power consumption side node, the carbon emissions calculation process is similar to that of the second-level node. The difference is that when the third-level node calculates carbon emissions, the parameters of the upper-level node that need to be obtained are the carbon emission factor, forward power, reverse power, self-built power grid power and self-built power carbon emissions, and the carbon emissions of the self-built power are recorded as 0.

[0038] In one embodiment, the specific process of determining the corresponding carbon emission flow direction based on the power in the real-time carbon emission data is: S321, matching the electric quantity with the node based on the corresponding relationship between the real-time carbon emission data and the node, and dividing the electric quantity corresponding to the node into forward electric quantity and reverse electric quantity according to the direction of electric energy flow corresponding to the electric quantity; S322, accumulating and calculating the forward power and the reverse power to obtain the node accumulated power, and determining the flow direction of the carbon emission of the corresponding node according to the node accumulated power and the preset carbon emission direction.

[0039] In this embodiment, although the node has obtained the forward and reverse electricity of the corresponding upper node during the calculation of carbon emissions, in order to ensure the accuracy of the forward and reverse electricity, the node electricity data is matched and the direction is confirmed again, and the electricity data is accumulated and calculated based on the node. If the forward and reverse electricity are accumulated to be positive, the corresponding initial input and output directions of the electric carbon calculation device based on the on-site installation situation are set as the flow direction of the node carbon emissions. If the forward and reverse electricity are accumulated to be negative, the opposite direction of the initial input and output directions of the electric carbon calculation device based on the on-site installation situation is set as the flow direction of the node carbon emissions.

[0041] In this embodiment, the final carbon flow monitoring visualization function interface is formed according to the finally collected carbon emission data and combined with the physical topology.

[0042] This embodiment has at least the following substantial effects: This embodiment establishes an electric-carbon topology structure based on the distribution network topology structure, obtains the correspondence between the current and the carbon flow in the distribution network, sets the carbon emission factor according to the electric-carbon topology structure, collects real-time carbon emission data based on the electric-carbon topology structure, and hierarchically sorts the nodes in the electric-carbon topology structure to obtain a row node set, clarifies the priorities of different nodes, enhances the hierarchy and logic of different nodes and the carbon data corresponding to the nodes, then calculates the carbon emissions according to the real-time carbon emission data, the carbon emission factor and the row node set, quantifies the carbon emissions of the nodes according to the hierarchy and logic of the nodes, determines the flow direction of the corresponding carbon emissions based on the electricity in the real-time carbon emission data, clarifies the carbon flow, that is, the flow direction of the carbon emissions, and the hierarchy, logic and flow direction corresponding to the carbon emissions can also be The corresponding carbon flow path is obtained in combination with the electric-carbon topological structure. Finally, the final carbon flow monitoring visualization function interface, i.e., the real-time electric-carbon topological map, is established based on the carbon emissions, flow direction, real-time carbon emission data and the electric-carbon topological structure. The real-time electric-carbon topological map is used to visualize the carbon emissions, carbon emission sources and the flow direction of carbon emissions, and then the corresponding carbon flow path and other information can be observed. It not only refines the carbon flow data, but also reflects the actual carbon emission situation in real time, and can also realize accurate carbon emission data traceability and supervision according to the carbon flow path and the flow direction of carbon emissions. After the data traceability is completed, the position of the abnormal data in the distribution network topology structure corresponding to the abnormal data can be accurately judged based on the position of the abnormal data in the electric-carbon topological structure combined with the correspondence between current and carbon flow, so as to realize accurate positioning of abnormal carbon emissions.
