By identifying the functional behavior of the actual production and support activities occurring in the manufacturing base, a mapping relationship between the functional behavior unit and the emission elements is established based on the behavior type and the energy or material category. Taking the functional behavior unit as the reverse starting point, the candidate carbon emission accounting boundary object set is generated combined with the actual running state in the accounting period, and the time attribute is introduced to depict the emission characteristics of the emission objects in different time periods and the switching and alternating running processes. The emission contribution of each candidate object is quantified and compared with the preset threshold value to realize the candidate object pruning, and finally the carbon emission accounting boundary matched with the actual running of the manufacturing base is determined. The scheme can accurately reflect the complex running behavior and time variation characteristics, and improve the accuracy and consistency of the carbon emission accounting boundary determination.

Description

Technical Field

[0001] This invention relates to the field of carbon emission accounting technology, specifically to a method and system for determining the carbon emission accounting boundary of a highway engineering industrial manufacturing base. Background Technology

[0002] With the continuous advancement of dual-carbon goals, carbon emission accounting in the engineering construction field has gradually become an important foundation for project management, green assessment, and policy supervision. As an important component of infrastructure construction, highway engineering is characterized by long construction cycles, high energy consumption, and complex emission sources, making systematic and scientific carbon emission accounting urgently needed.

[0003] In recent years, industrialized manufacturing bases for highway engineering have been widely used as important production carriers for specific highway engineering projects, in the production of precast components, raw material processing, and centralized construction support. During the construction period, these manufacturing bases typically exhibit characteristics of being project-demand oriented, having distinct operational phases, and diverse functional units. They include both high-emission activities such as precast production, equipment operation, and material transportation, as well as low-emission activities such as temporary facility operation and greening maintenance.

[0004] Existing carbon emission accounting methods mostly use fixed spatial boundaries or fixed facility lists to determine the accounting scope, that is, using buildings, equipment or functional areas within the manufacturing base as the basis for delineating the accounting boundaries. However, such methods are difficult to adapt to the dynamic changes in functional behavior of industrialized manufacturing bases for highway engineering at different construction stages and under different production organization models. They tend to include a large number of objects with small contributions to carbon emissions in the accounting scope, resulting in redundant accounting objects, large data collection workload, high accounting costs, and difficulty in highlighting the impact of major emission sources on the overall results.

[0005] Furthermore, existing technologies generally focus on the calculation of emissions themselves, lacking a systematic approach to the scientific determination of accounting boundaries. In particular, there is a lack of a technical solution that can dynamically determine accounting boundaries based on the actual functional behavior of the manufacturing base and the degree of emission contribution. Therefore, how to reasonably determine the carbon emission accounting boundaries of industrialized manufacturing bases for highway engineering while ensuring the accuracy of carbon emission accounting, reducing accounting complexity, and improving the targeting of accounting has become an urgent technical problem to be solved in this field. Summary of the Invention

[0006] In view of the above-mentioned shortcomings mentioned in the background art, the purpose of this invention is to provide a method and system for determining the carbon emission accounting boundary of a highway engineering industrial manufacturing base.

[0007] The first aspect of the present invention provides a method for determining the carbon emission accounting boundary of a highway engineering industrial manufacturing base, the method comprising the following steps: S1, perform functional behavior identification on the actual activities occurring in the manufacturing base, break down the activities into several functional behavior units, and establish structured parameters for each functional behavior unit, including the behavior type and the energy or material category involved. S2, Based on the structured parameters, construct the mapping relationship between each functional behavior unit and emission elements, wherein the emission elements include at least energy consumption, material and consumable consumption, site transportation activities, greenhouse gas emissions and vegetation carbon sink elements; S3. Based on the mapping relationship, generate a set of candidate carbon emission accounting boundary objects with the functional behavior unit as the starting point for reverse calculation; S4. Based on the energy consumption, material or transportation workload corresponding to the candidate carbon emission accounting boundary objects, the emission contribution of each candidate carbon emission accounting boundary object in the predetermined accounting period is quantitatively characterized. S5. Based on the comparison result between the emission contribution and the preset threshold, the set of candidate carbon emission accounting boundary objects is trimmed to generate a carbon emission accounting boundary corresponding to the manufacturing base.

[0008] A second aspect of this invention provides a system for determining the carbon emission accounting boundary of an industrialized manufacturing base for highway engineering. The system includes: a functional behavior identification module, used to identify the functional behaviors of actual activities occurring within the manufacturing base, breaking down the activities into several functional behavior units, and establishing structured parameters for each functional behavior unit, including the behavior type and the energy or material category involved; and a mapping relationship construction module, used to construct a mapping relationship between each functional behavior unit and emission elements based on the structured parameters, wherein the emission elements include at least energy consumption, material and consumable consumption, site transportation activities, and greenhouse gas emissions. The system includes: a vegetation carbon sink element; a candidate boundary object generation module, used to generate a set of candidate carbon emission accounting boundary objects based on the mapping relationship and with functional behavior units as the starting point for back-calculation; an emission contribution quantification module, used to quantify the emission contribution of each candidate carbon emission accounting boundary object within a predetermined accounting period based on the energy consumption, material or transportation workload corresponding to the candidate carbon emission accounting boundary object; and a boundary trimming module, used to trim the set of candidate carbon emission accounting boundary objects based on the comparison result of the emission contribution and a preset threshold, to generate a carbon emission accounting boundary corresponding to the manufacturing base.

[0009] Compared with the prior art, the present invention has at least the following beneficial technical effects: The present invention identifies the functional behavior of actual activities occurring in the industrialized manufacturing base of highway engineering, and derives candidate carbon emission accounting boundary objects based on the mapping relationship between functional behavior units and emission elements. It introduces time attributes to characterize the emission characteristics generated by emission objects in different time periods and during switching and alternating operations, and quantifies and trims the emission contribution of candidate objects. This enables the carbon emission accounting boundary to truly reflect the complex operating behavior and time-varying characteristics of the manufacturing base, avoiding the problem of repeated or omitted emissions in traditional fixed boundary methods. While ensuring the accuracy and consistency of the accounting, it improves the refinement and feasibility of determining the carbon emission accounting boundary. Attached Figure Description

Detailed Implementation

[0011] The specific embodiments of this disclosure will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit this disclosure.

[0012] The carbon emission accounting boundary determination method described in this embodiment can be deployed on the production management server, park-level energy and carbon management platform, enterprise-level carbon emission accounting system, or cloud management platform corresponding to the industrialized manufacturing base of highway engineering. It is used to uniformly collect, correlate, analyze, and identify the operating status, energy and material consumption of multiple production facilities, auxiliary equipment, and operational activities (such as component production equipment, energy supply equipment, site transportation vehicles, material consumption nodes, greening units, and related metering points) within the manufacturing base.

[0013] The management platform provides functional pages such as an overview of the manufacturing base operation, a view of functional behavior unit division, a display of the correlation between emission elements, time-dimensional emission analysis, a list of candidate accounting boundary objects, and a comparison of accounting results. It provides a carrier interface and business entry point for the data collection, accounting boundary determination results display, and subsequent carbon emission accounting and management decisions of this invention.

[0014] For ease of understanding, the following description focuses on multiple production and support activities within a highway engineering industrial manufacturing base. The production facilities, auxiliary equipment, and operational activities are not necessarily limited to direct physical connections, energy connections, or management affiliations. The relationship between the functional behavioral units and emission targets described in this invention is constructed based on the actual operational behavior of the manufacturing base within the accounting period, energy and material consumption records, and changes in operational status over time. Essentially, it is a structured modeling and quantitative inference of the relationship between the manufacturing base's operational activities and emission elements, rather than isolated statistics on a single piece of equipment or a single emission source.

[0015] Please see Figure 1 This invention provides a method for determining the carbon emission accounting boundary of an industrialized manufacturing base for highway engineering. The method includes the following steps: S1, identifying the functional behaviors of activities actually occurring within the manufacturing base, breaking down the activities into several functional behavior units, and establishing structured parameters for each functional behavior unit, including the behavior type and the energy or material category involved. In this step, each type of activity actually occurring in the manufacturing base within a predetermined accounting period is identified. The activities may include component production operations, raw material processing, equipment operation, material or component transfer within the site, equipment maintenance, site lighting operation, and greening maintenance, etc. It should be noted that only activities that actually occur within the accounting period and can generate energy or material consumption, transportation activities, or carbon sequestration effects are identified.

[0016] As an example, functional behavior identification is performed on the actual activities occurring within the manufacturing base, and the activities are broken down into several functional behavior units, including: classifying the activities according to their corresponding production or support purposes; grouping activities with the same or similar functional attributes that occur continuously within the same time period into the same functional behavior unit; and classifying activities with differences in functional attributes, energy or material categories into different functional behavior units.

[0017] In practice, the production or support purpose of an activity is first determined based on its direct impact on the manufacturing base's operational system. For example, activities directly used to form components, such as mixing, pouring, and curing, have a clear production purpose; while activities used to ensure the normal operation of the above-mentioned production activities, such as lighting, ventilation, equipment standby, and maintenance, are determined to have a support purpose.

[0018] After classifying the functional attributes, the occurrence of activities over time is further assessed. Activities that occur consecutively within the same time period and have consistent functional attributes, even if performed by different equipment or in different physical locations, are grouped into the same functional behavior unit as long as they serve the same production or support purpose and involve the same type of energy or materials. For example, within the same production shift, multiple mixing machines may be located on different production lines, but they all continuously perform concrete mixing operations, have the same production purpose, consistent functional attributes, and involve the same type of energy (electricity). Therefore, these activities are grouped into the same concrete mixing production functional behavior unit. This approach avoids over-segmentation of functional behavior units due to differences in the number or location of equipment.

[0019] On the other hand, when activities differ in functional attributes or the types of energy or materials involved, they should be classified into different functional behavioral units even if they overlap in time. For example, concrete mixing operations and on-site component transfer operations that occur within the same time period have different production purposes, different functional attributes, and different types of energy involved, and should therefore be classified into different functional behavioral units.

[0020] Furthermore, when the energy or material categories of the same type of activity change during the accounting period, for example, the production of the same component is supported by mains power equipment during some time periods and by diesel generator equipment during other time periods, due to the different energy categories involved, it should be identified as different operating states under the same functional behavior unit in subsequent steps, rather than being forcibly split into different functional behavior units in this step, so as to ensure the consistency of functional behavior unit division at the functional level.

[0021] After identifying and decomposing the functional behavioral units, structured parameters are established for each functional behavioral unit to characterize its behavior type and the energy or material category involved. It is understood that these structured parameters serve as the foundational data for subsequently constructing the mapping relationship between functional behavioral units and emission factors.

[0022] S2, Based on the structured parameters, a mapping relationship is constructed between each functional behavioral unit and emission elements. The emission elements include at least energy consumption, material and consumable consumption, site transportation activities, greenhouse gas emissions, and vegetation carbon sinks. In this step, based on the structured parameters established for each functional behavioral unit, the types of emission elements involved in carbon emission accounting are determined for each functional behavioral unit. It should be noted that the construction of the mapping relationship is directly based on the behavioral type of the functional behavioral unit and the category of energy or materials involved, and not on equipment name, spatial location, or management affiliation.

[0023] As an example, constructing a mapping relationship between each functional behavior unit and emission elements based on the structured parameters includes: determining the energy consumption emission elements, material and consumable consumption emission elements corresponding to the functional behavior unit based on the behavior type and the energy or material category involved in the structured parameters; determining the site transportation activity emission elements corresponding to the functional behavior unit when the behavior type is characterized as material or component transfer behavior; and determining the greenhouse gas emission elements or vegetation carbon sink emission elements corresponding to the functional behavior unit when the behavior type is characterized as emission source behavior or carbon sink behavior.

[0024] In practice, for each functional behavior unit, its corresponding behavior type and the category of energy or material involved are first read. When the behavior type is represented as production or operation behavior, and the energy category involved is electricity, fuel, or other energy medium, the functional behavior unit is mapped to energy consumption emission elements; when the material category involved is cement, steel bars, admixtures, or other production consumables, the functional behavior unit is further mapped to material and consumable consumption emission elements.

[0025] For example, for a concrete mixing production functional unit, its behavior type is production behavior, the energy category involved is electricity, and the material categories involved include cement, aggregates, and admixtures. Therefore, this functional unit simultaneously corresponds to both energy consumption emission factors and material and consumable consumption emission factors. This approach ensures that the same functional unit is not simplified to a single emission source at the emission factor level, thus avoiding accounting omissions.

[0026] When the behavior type of a functional behavioral unit is characterized as material or component transfer behavior, such as short-distance transfer of components within the site using forklifts or transport vehicles, then in addition to the aforementioned energy or material consumption emission factors, its corresponding emission factor is further determined as the site transportation activity emission factor. It should be noted that this determination is not based on transportation distance or scale, but solely on whether the behavior type belongs to transfer behavior.

[0027] Furthermore, when the behavior type of a functional behavioral unit is characterized as either an emission source behavior or a carbon sink behavior, its corresponding emission element is determined to be either a greenhouse gas emission element or a vegetation carbon sink emission element, respectively. For example, for a greening maintenance functional behavioral unit within the site, whose behavior type is characterized as a carbon sink behavior, it is mapped to a vegetation carbon sink emission element; for combustion or process behavioral units that have direct greenhouse gas emissions, they are mapped to greenhouse gas emission elements.

[0028] It should be further explained that, in this embodiment, the same functional behavioral unit can simultaneously correspond to one or more emission elements. The above mapping relationship is not a one-to-one correspondence, but a multi-element mapping relationship based on structured parameters. In this way, it can be ensured that when generating candidate carbon emission accounting boundary objects in subsequent steps, emission sources are not omitted or double-counted due to overly simplified mapping relationships.

[0029] S3. Based on the mapping relationship, a set of candidate carbon emission accounting boundary objects is generated with the functional behavior unit as the starting point for reverse deduction. In this step, based on the mapping relationship between the functional behavior unit and emission elements that has been constructed in step S2, the actual operation of each functional behavior unit in the accounting cycle is analyzed, and on this basis, the emission objects that are actually associated with the functional behavior unit in the actual operation process are deduced, thereby forming a set of candidate carbon emission accounting boundary objects.

[0030] As an example, based on the mapping relationship, a set of candidate carbon emission accounting boundary objects is generated using functional behavioral units as the starting point for back-calculation. This includes: for each functional behavioral unit, obtaining its actual occurrence status within a predetermined accounting period, and determining the emission element combination corresponding to the functional behavioral unit in different time periods based on the actual occurrence status. In this embodiment, for each functional behavioral unit, its actual occurrence status within the predetermined accounting period is first obtained. The actual occurrence status is used to characterize whether the functional behavioral unit occurs within the accounting period, the start and end times of occurrence, and the duration. The actual occurrence status can be determined through information such as production records, equipment operation logs, energy consumption metering records, and work shift arrangements. It should be noted that only when the functional behavioral unit actually occurs within the accounting period is its corresponding time period considered as a valid time period for subsequent analysis; time periods that do not actually occur or are only planned but not executed are not included in the subsequent emission object back-calculation process.

[0031] After obtaining the actual occurrence status of the functional behavior unit, the accounting period is divided into time periods based on the changes in the operational status of the functional behavior unit within the accounting period. The time periods can be divided according to shifts, work stages, or continuous operation intervals, as long as they can reflect the time nodes when the operational status of the functional behavior unit changes.

[0032] Within each time period, based on the aforementioned mapping relationship, the emission element combination for that functional behavioral unit within the corresponding time period is determined. The emission element combination may include one or more emission elements. For example, within a certain time period, a component production functional behavioral unit may simultaneously correspond to energy consumption emission elements and material and consumable consumption emission elements; within another time period, when backup energy equipment is activated, it may correspond to different types of energy consumption emission elements. By determining the emission element combination according to time periods, the differences in emission characteristics of the functional behavioral unit under different operating states can be reflected.

[0033] Based on the combination of emission elements, the emission objects actually associated with the functional behavioral unit within the corresponding time period are deduced. Only emission objects that are actually associated with the functional behavioral unit within the accounting period are included in the candidate carbon emission accounting boundary object set. In this embodiment, after determining the combination of emission elements for each time period, the emission objects actually associated with the functional behavioral unit within the corresponding time period are deduced based on the combination of emission elements. The emission objects can be specific equipment, facilities, or other objects that can directly generate or bear emissions. An emission object is considered to have an actual association with the functional behavioral unit only if it actually participates in the operation of the functional behavioral unit within the corresponding time period. For example, when the emission element corresponding to a certain time period is electrical energy consumption, only electrical equipment that actually operates and supplies energy to the functional behavioral unit within that time period is considered as emission objects; equipment that is not operating or is only in standby mode is not included in the candidate set as emission objects. This method avoids mistakenly including objects that are only spatially or managerially related but not temporally involved in the accounting boundary.

[0034] When the emission objects corresponding to the same functional behavior unit are inconsistent in different time periods, the emission objects corresponding to each time period are included in the candidate carbon emission accounting boundary object set as independent candidate carbon emission accounting boundary objects. In this embodiment, when the emission objects corresponding to the same functional behavior unit are inconsistent in different time periods, for example, when the unit is supported by mains power equipment in some time periods and by diesel generator equipment in other time periods, the emission objects derived from different time periods are included in the candidate set as independent candidate carbon emission accounting boundary objects.

[0035] The above-mentioned splitting process ensures that emission sources formed under different operating conditions remain distinct in the candidate set, thereby avoiding the merging of emission sources due to changes in emission objects over time, which could lead to unclear emission sources or distorted accounting results.

[0036] When the same emission object is associated with the functional behavior unit only for a portion of the time period within the accounting period, the emission object is included in the candidate carbon emission accounting boundary object set as a candidate carbon emission accounting boundary object with time attributes, according to its associated time range.

[0037] In this embodiment, when the same emission object is associated with a certain functional behavior unit only for a part of the accounting period, the emission object is not included in the candidate set as a whole for the entire accounting period. Instead, it is included in the candidate set as a candidate carbon emission accounting boundary object with time attributes according to the associated time range in which it actually participates in the operation.

[0038] By introducing a time attribute, the effective participation time range of emission objects within the accounting period can be clearly defined, providing precise time boundary conditions for the subsequent quantification of emission contributions.

[0039] As an example, incorporating the emission object into the candidate carbon emission accounting boundary object set as a candidate carbon emission accounting boundary object with time attributes according to its associated time range includes: when the same emission object switches or alternates between different functional behavioral units within the accounting cycle, identifying the start and end time periods corresponding to the switching or alternating operation; determining the associated time range of the start-up, shutdown, no-load, preheating, or efficiency change processes caused by the switching or alternating operation based on the start and end time periods; and incorporating the emission object corresponding to the carbon emissions generated within the associated time range into the candidate carbon emission accounting boundary object set as a candidate carbon emission accounting boundary object with independent time attributes.

[0040] When an emission object switches or alternates between different functional behavioral units, emissions generated during start-up, shutdown, no-load, preheating, or efficiency changes are not directly formed by any single functional behavioral unit under its stable operating state. Their emission formation mechanism differs from emissions during the stable operation phase. Furthermore, these switch-induced emissions typically occur in short-term phases when the emission object's operating state changes, exhibiting instantaneous and irreversible characteristics over time, making it impossible to reasonably allocate them based on operating time or load ratios. Directly incorporating these emissions into the emission object corresponding to the preceding or subsequent functional behavioral unit can easily lead to unclear emission attribution, or even double counting or complete omission across multiple functional behavioral unit accounting boundaries.

[0041] Therefore, when the same emission object switches or alternates between different functional behavioral units within the accounting period, the time boundary of the change in the functional behavioral unit served by the emission object is first clearly defined by identifying the start and end time periods corresponding to the switch or alternation. This definition allows for the differentiation of the emission object's operating status in the time dimension when it is stably operating in the previous functional behavioral unit, stably operating in the next functional behavioral unit, or in the process of functional switching, thus avoiding unclear emission attribution time boundaries due to changes in the operating service object.

[0042] After clearly defining the start and end time periods for switching or alternating operation, the starting and ending time periods are further used to identify the start-up, shutdown, no-load, preheating, or efficiency change processes experienced by the emission object during the switching process, and these operational state change processes are defined as independent associated time ranges. It should be noted that the emissions corresponding to this associated time range are not directly generated by any functional unit under its normal production or maintenance state, but are objectively formed by the emission object during the adjustment of its operational state. If this time range is not separately defined, it is easy to mistakenly include this part of the emissions in the stable operation emissions of the preceding or subsequent functional unit.

[0043] After defining the aforementioned time frame, emission objects that generate carbon emissions only within the defined time frame are included in the candidate carbon emission accounting boundary object set as candidate objects with independent time attributes, instead of merging them with candidate objects corresponding to emission objects during stable operation. By making the emission objects corresponding to switching-induced emissions independent items, accounting errors caused by switching emissions being repeatedly included in multiple functional units or ignored entirely can be avoided when the same emission object frequently switches or alternates in operation. This results in a clear and non-overlapping time boundary structure in the candidate carbon emission accounting boundary object set.

[0044] S4, based on the energy consumption, material or transportation workload corresponding to the candidate carbon emission accounting boundary objects, the emission contribution of each candidate carbon emission accounting boundary object within a predetermined accounting period is quantitatively characterized; in this embodiment, for any candidate carbon emission accounting boundary object... The corresponding emission contribution is defined as The emission contribution rate is used to characterize the magnitude of the candidate's contribution to overall carbon emissions within the accounting period. Specifically, the emission contribution rate can be quantified as follows: ;in, Indicates candidate objects Within the accounting period or its associated time frame, the basic measurement quantity corresponding to the kth type of emission element, This represents the emission factor corresponding to the emission element, and n represents the number of emission element types involved in the candidate object. Using the above calculation method, the emission impacts of different emission elements can be uniformly summarized into a single emission contribution index.

[0045] In practice, the basic measurement quantity is determined based on the emission element type corresponding to the candidate. The specific determination should be made. For example, when a candidate object corresponds to an energy consumption emission factor, its basic measurement can be directly adopted from the energy consumption of that candidate object within the accounting period or related time range. At this time there is When a candidate object corresponds to the emission factors of material and consumable consumption, its basic measurement quantity can be the consumption of the corresponding material or consumable. ,Right now .

[0046] For candidate emission elements related to transportation activities within the corresponding site, their basic measurement quantity can be characterized by transportation workload, for example, by accumulating the distance and load capacity of multiple transportation processes. The basic measurement quantity can then be expressed as: ;in, This represents the transport distance of the j-th transport. This represents the corresponding transport capacity, and m represents the number of transport trips. Using this method, the emission impact of on-site transport activities within the accounting period can be converted into basic measurement quantities that can be used for unified calculations.

[0047] When a candidate object corresponds to a vegetation carbon sink emission element, its basic measurement is the carbon sink amount formed by the candidate object within the accounting period or related time range. And it participates in the calculation of emission contribution in the form of a negative value, that is This allows carbon absorption to offset other emissions.

[0048] Furthermore, for the candidate carbon emission accounting boundary objects with time attributes determined in step S3, their emission contribution is quantified only within their corresponding associated time range. In this case, their emission contribution can be expressed as: ;in, Indicates the candidate object within its associated time range The basic measurement of the corresponding emission elements. By limiting the quantification time range, it is possible to avoid incorrectly including emissions generated by candidate objects during the stable operation phase in the emission contributions caused by switching or alternating operation.

[0049] After completing the above emission contribution calculations, to facilitate comparisons between different candidates, the emission contributions of each candidate can be normalized. For example, the relative emission contribution can be calculated as follows: ;in, This indicates the number of candidate carbon emission accounting boundary objects. Through normalization, the emission contributions of different candidate objects can be converted into relative indicators under a unified scale, thus providing a direct basis for comparing the emission contributions with the preset threshold in the subsequent step S5.

[0050] It should be noted that the above formula is only used to illustrate one specific implementation of emission contribution quantification. Other equivalent quantification methods can also be used without deviating from the technical concept of this invention, which will not be elaborated here.

[0051] S5. Based on the comparison result between the emission contribution and the preset threshold, the set of candidate carbon emission accounting boundary objects is trimmed to generate a carbon emission accounting boundary corresponding to the manufacturing base.

[0052] In this step, based on the emission contribution of each candidate carbon emission accounting boundary object obtained in step S4, the candidate objects are screened to determine the final set of objects to be included in the carbon emission accounting boundary. It should be noted that the purpose of this pruning step is to remove objects whose impact on overall carbon emissions is negligible, while ensuring the integrity of the accounting results, thereby avoiding excessive expansion of the accounting boundary.

[0053] In this embodiment, the preset threshold is used to characterize the minimum contribution level of a candidate carbon emission accounting boundary object that should be included in the overall carbon emission accounting boundary. The preset threshold can be set according to the scale of the manufacturing base, accounting accuracy requirements, or management needs. For example, the preset threshold can be expressed as a relative emission contribution threshold. This means that when the relative emission contribution of a candidate is not lower than the threshold, it is considered to have a non-negligible impact on overall carbon emissions.

[0054] After completing the emission contribution normalization process in step S4, each candidate carbon emission accounting boundary object Corresponding to a relative emission contribution In this embodiment, the relative emission contribution is compared with a preset threshold to determine whether the candidate should be included in the final carbon emission accounting boundary. Specifically, when the following conditions are met... At that time, the candidate carbon emission accounting boundary objects will be... If a candidate is deemed to meet the inclusion criteria, it is considered to meet the inclusion criteria. If the above criteria are not met, the candidate is deemed not to meet the inclusion criteria.

[0055] By using the above comparison method, candidates with high emission contributions and significant impact on overall carbon emissions can be selected.

[0056] In this embodiment, for the candidate carbon emission accounting boundary objects with time attributes determined in step S3, the pruning rules are consistent with those for candidate objects without time attributes, but their emission contribution is... Calculations are based solely on emissions within their relevant timeframe. For example, for candidate emissions with independent time attributes caused by switching or alternating operation, they are only included in the final carbon emission accounting boundary if their relative emission contribution within the relevant timeframe meets a threshold condition. This approach avoids unconditional inclusion due to short switching-induced emission periods or unreasonable neglect due to their short duration.

[0057] After comparing emission contributions with thresholds, the set of candidate carbon emission accounting boundary objects is pruned. In practice, all objects meeting the criteria are... Candidate objects that meet the condition are retained in the set, while candidate objects that do not meet the condition are removed from the set, thus forming a pruned candidate set.

[0058] It should be noted that this trimming process is carried out at the candidate object level and does not change the time attribute, emission element type or associated time range determined in step S3. It only makes a judgment on whether to include it in the final accounting boundary.

[0059] After the above-mentioned trimming is completed, the candidate carbon emission accounting boundary objects retained in the trimmed set collectively constitute the carbon emission accounting boundary corresponding to the manufacturing base. The carbon emission accounting boundary clearly defines the emission objects that need to be included in the carbon emission accounting within the accounting period and their corresponding time range.

[0060] By following the steps above, we can ensure the representativeness of the emission accounting results while avoiding increasing the accounting complexity by including too many objects with low emission contributions, thereby achieving a balance between accounting accuracy and implementation cost.

[0061] Please see Figure 2 This invention also provides a carbon emission accounting boundary determination system 100 for highway engineering industrial manufacturing bases, the system comprising: The functional behavior identification module 10 is used to identify the functional behaviors of actual activities occurring within the manufacturing base, decompose the activities into several functional behavior units, and establish structured parameters for each functional behavior unit, including the behavior type and the energy or material category involved. The mapping relationship construction module 20 is used to construct a mapping relationship between each functional behavior unit and emission elements based on the structured parameters. The emission elements include at least energy consumption, material and consumable consumption, site transportation activities, greenhouse gas emissions, and vegetation carbon sink elements. The candidate boundary object generation module 30 is used to generate a set of candidate carbon emission accounting boundary objects based on the mapping relationship, with the functional behavior units as the starting point for back-calculation. The emission contribution quantification module 40 is used to quantify the emission contribution of each candidate carbon emission accounting boundary object within a predetermined accounting period based on the energy consumption, material or transportation workload corresponding to the candidate carbon emission accounting boundary objects. The boundary trimming module 50 is used to trim the set of candidate carbon emission accounting boundary objects based on the comparison result of the emission contribution and a preset threshold, generating a carbon emission accounting boundary corresponding to the manufacturing base.
