Abstract
Description
Technical Field
[0001] This invention relates to a method, system, equipment, and storage medium for constructing a corporate carbon emission reduction profile, belonging to the field of carbon emission management technology. Background Technology
[0002] For businesses, carbon reduction is not only a global environmental responsibility but also an urgent business challenge. Businesses use large amounts of energy, especially fossil fuels, in their production processes, resulting in significant carbon dioxide emissions. A company's carbon emissions directly impact its competitiveness in domestic and international markets.
[0003] In recent years, global regulations on corporate carbon emissions have intensified, prompting companies to reduce carbon emissions during production processes. This is particularly true for high-carbon-emission industries such as power, steel, and cement, where policies have become increasingly stringent. Companies not only need to comply with relevant policies and regulations but also face the pressure of rising carbon emission costs.
[0004] Furthermore, with increasing consumer awareness of environmental protection, green consumption has become an important criterion for more and more consumers when choosing products and services. A company's carbon emissions have become a key factor in consumer decision-making. Achieving low-carbon production and promoting green transformation have become core tasks for companies to enhance their market competitiveness and increase brand value. Summary of the Invention
[0005] To address the problems existing in the prior art, this invention proposes a method, system, device, and storage medium for constructing a corporate carbon emission reduction profile.
[0006] The technical solution of the present invention is as follows: On the one hand, this invention provides a method for constructing a corporate carbon emission reduction profile, including the following steps: Collect carbon emission data from different data sources within a fixed time period and perform preprocessing. A carbon emission model is constructed to calculate the carbon emissions of enterprises within different preset ranges during fixed time periods based on preprocessed enterprise carbon emission data. By combining the carbon emissions of enterprises within different preset ranges over a fixed period, a tiered carbon reduction profile is constructed for the current fixed period. By combining the stratified carbon emission reduction profiles of enterprises across all fixed time periods, an overall carbon emission reduction profile of the enterprise can be constructed.
[0007] Preferably, the preprocessing step includes data cleaning, and after data cleaning, time synchronization of enterprise carbon emission-related data from different data sources within a fixed time period.
[0008] Preferably, the carbon emissions of the enterprise within different preset ranges include the enterprise's direct carbon emissions and indirect carbon emissions.
[0009] Preferably, the formula for calculating the direct carbon emissions is: ; in: This indicates the company's direct carbon emissions; Indicates the total number of combustion sources for the enterprise; Indicates the end time; Indicates the start time; Represents the integral variable; express Time of the first The real-time volume of the combustion source; Indicates the first The density of the combustion source; Indicates the first The high heating value of this type of combustion source; Indicates the first The carbon content of a combustion source; express Time of the first The unburned carbon fraction of a combustion source; express Time of the first The oxidation rate of a combustion source.
[0010] Preferably, the formula for calculating the indirect carbon emissions is: ; in: This indicates the company's indirect carbon emissions; Indicates the total number of enterprise websites; Indicates the total duration of a fixed time period; Indicates the first Each enterprise website Real-time electricity purchase volume; Indicates the first Each enterprise website The percentage of renewable electricity at any given time; express The grid emission factor at any given time; express The green electricity emission factor of the power grid at any given time.
[0011] Preferably, after setting different weights for the stratified carbon emission reduction profiles for different fixed time periods, the overall carbon emission reduction profile is obtained by weighted summation of the stratified carbon emission reduction profiles for all fixed time periods.
[0012] On the other hand, a corporate carbon emission reduction profile construction system includes a data acquisition module, a carbon emission calculation module, a time-sharing and hierarchical carbon emission reduction profile construction module, and an overall carbon emission reduction profile construction module. The data acquisition module is used to collect carbon emission-related data from different data sources within a fixed time period and to perform preprocessing. The carbon emission calculation module is used to construct a carbon emission model and calculate the carbon emissions of enterprises within different preset ranges during a fixed period based on the preprocessed enterprise carbon emission-related data. The time-based and layered carbon emission reduction profile construction module is used to construct a layered carbon emission reduction profile for the current fixed time period by comprehensively considering the carbon emissions of enterprises within different preset ranges over a fixed time period. The overall carbon emission reduction profile construction module is used to construct the overall carbon emission reduction profile of an enterprise by integrating the hierarchical carbon emission reduction profiles of all fixed time periods.
[0013] In another aspect, the present invention also provides an electronic device, including a memory, a processor, and a computer program stored in the memory and executable on the processor, wherein the processor executes the program to implement the method described in the present invention.
[0014] In another aspect, the present invention also provides a computer-readable storage medium having a computer program stored thereon that, when executed by a processor, implements the method described in the present invention.
[0015] The present invention has the following beneficial effects: 1. This invention improves traceability by separately accounting for direct and indirect carbon emissions, avoiding duplication or omission.
[0016] 2. This invention first constructs a "layered profile" for a single fixed time period, and then overlays it across time periods to form an overall profile. This can capture peak / valley emission characteristics and intuitively display the emission weights of different business units, providing a quantitative basis for differentiated energy-saving renovations or performance evaluations.

[0025] In one specific embodiment, the data cleaning includes removing outliers and filling in missing values.
[0026] In one specific embodiment, since data from different data sources have different sampling frequencies, it is necessary to synchronize the carbon emission data of enterprises from different data sources within a fixed time period.

[0029] In one specific embodiment, the combustion source refers to all devices or activities within the boundaries of an enterprise organization that directly emit greenhouse gases through fuel thermochemical reactions, and can be specifically divided into stationary combustion sources and mobile combustion sources; The specific fixed combustion sources are shown in the table below:

[0032] In one specific embodiment, an enterprise site represents each business or geographical unit within an enterprise that has an independent energy metering boundary. It can be divided by geographical location or by functional / business unit, as long as the following two conditions are met: 1. Have independent energy metering or billing: such as having an independent main electricity meter / heat meter / distributed photovoltaic metering or being able to obtain time-of-use (preferably hourly) energy consumption data.
[0033] 2. Carbon accounting needs to be presented or managed separately: different operating entities (subsidiaries, branches), different applicable energy structures (e.g., one plant uses 100% green electricity, while another plant uses thermal power), and have separate energy conservation, emission reduction or compliance targets.
[0034] In one specific embodiment, the power grid emission factor is calculated by taking a weighted average of the instantaneous output and emission intensity of all generating units in the power grid at each dispatch interval.
[0035] In one specific embodiment, the green electricity emission factor of the power grid is considered to be 0.
[0036] In some embodiments, after setting different weights for the stratified carbon emission reduction profiles for different fixed time periods, the overall carbon emission reduction profile is obtained by weighted summation of the stratified carbon emission reduction profiles for all fixed time periods.
[0037] In one specific embodiment, the overall carbon emission reduction profile of the enterprise is shown in the table below:
[0038] As can be seen from the overall carbon emission reduction profile above, indirect carbon emissions are the primary concern for enterprises in reducing emissions.
[0039] In some embodiments, an enterprise carbon emission reduction profile construction system is proposed, including a data acquisition module, a carbon emission calculation module, a time-sharing and hierarchical carbon emission reduction profile construction module, and an overall carbon emission reduction profile construction module; The data acquisition module is used to collect carbon emission-related data from different data sources within a fixed time period and to perform preprocessing.
