[0052] The technical solutions in the embodiments of the present disclosure will be clearly and completely described below in conjunction with the drawings in the embodiments of the present disclosure. Obviously, the described embodiments are only part of the embodiments of the present disclosure, rather than all of the embodiments. The following description of at least one exemplary embodiment is actually only illustrative and is by no means intended to limit the present disclosure and its application or use. Based on the embodiments in the present disclosure, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present disclosure.
[0053] The relative arrangement of components and steps, the numerical expressions and numerical values set forth in these embodiments do not limit the scope of the present disclosure unless specifically stated otherwise.
[0054] At the same time, it should be understood that for the convenience of description, the sizes of the various parts shown in the drawings are not drawn according to the actual proportional relationship.
[0055] Technologies, methods, and apparatus known to ordinary technicians in the relevant field may not be discussed in detail, but where appropriate, such technologies, methods, and apparatus should be considered part of the authorization specification.
[0056] In all examples shown and discussed herein, any specific values should be interpreted as merely exemplary and not as limiting. Therefore, other examples of the exemplary embodiments may have different values.
[0057] It should be noted that like reference numerals and letters refer to similar items in the following figures, and therefore, once an item is defined in one figure, it need not be further discussed in subsequent figures.
[0058] Through research, the inventors found that by predicting the carbon emissions of discrete manufacturing enterprises, it is possible to effectively evaluate whether the enterprise's potential carbon emissions meet the emission requirements, evaluate the carbon emission quota compliance capabilities in advance, and prepare for the timely and full completion of carbon quota clearance. Therefore, the carbon emission prediction of discrete manufacturing enterprises has great research value.
[0059] In order to accurately calculate carbon emissions, relevant technical enterprises, factories or industrial parks conduct annual carbon emissions accounting for all greenhouse gas emission sources within the factory's operating scope, generally at the end of the accounting year or the beginning of the following year. Energy inventory data mainly based on electricity, steam, natural gas, gasoline, diesel, etc. are collected, and non-energy inventory data supplemented by welding shielding gas, refrigerants, etc. are collected. The total annual carbon emissions are calculated using the emission factor method.
[0060] Most of the prediction methods for the total carbon emissions of enterprises or factories use the historical carbon emission intensity reduction method, which forces the carbon emission intensity of previous years to be reduced to predict the total annual carbon emissions. For discrete enterprises with obvious annual output fluctuations, the total carbon emissions predicted based on output value and carbon emission intensity have the disadvantages of low accuracy and large deviation in prediction results.
[0061] Most of the carbon emission accounting and forecasting methods of related technologies are concentrated on methods based on statistical models, economic models, energy models and machine learning models. For forecasting methods based on historical data, commonly used statistical models are highly dependent on historical data; forecasting models based on economic theories and economic relationships consider the impact of factors such as the decline in carbon emission intensity and the growth of output value on carbon emissions, which often oversimplifies the actual situation and ignores the role of non-economic factors such as technical factors.
[0062] A carbon accounting prediction method of related technology analyzes electricity carbon accounting parameters and conducts model verification based on historical parameters, but does not have the ability to predict carbon accounting for discrete manufacturing companies.
[0063] Another related technology is based on the statistical information of the main energy consumption of a region or enterprise. It calculates the final carbon emissions after detailed decomposition of historical energy data. It cannot predict the total carbon emissions in the future.
[0064] Through research, the inventors found that the relevant technologies for carbon emission accounting and carbon emission forecasting for provinces, cities, parks, factories and other regions have the following problems.
[0065] (1) The total carbon emissions forecast based on historical data is essentially to use the method of analyzing historical energy consumption data to calculate the total carbon emissions for the accounting year based on the emissions in the past few years, or to convert the average emission level in the past few years based on the company's own output, output value and other information, and then calculate the total carbon emissions for the accounting year. Related technologies Such methods are based on years of accounting experience and accounting data. The carbon emissions forecast for a period of time in the future through the total carbon emissions or carbon emission intensity are greatly affected by production capacity fluctuations, the prediction results are low in accuracy, and the guidance ability for energy conservation and carbon reduction is weak.
[0066] (2) Establish a multi-attribute influencing factor model and a carbon emission prediction method based on a data-driven machine learning model. By analyzing carbon emissions over the past years, a big data model is trained to predict future carbon emissions. This type of method in related technologies overly relies on a large amount of accurate historical carbon emission data. Carbon emissions are affected by many factors, some of which have complex nonlinear relationships, and big data machine learning models cannot capture such complex relationships. At the same time, the carbon emission results predicted by black box models lack reasonable interpretability, which will limit the understanding and trust of the prediction results.
[0067] In view of at least one of the above technical problems, the present disclosure provides a method and device for predicting carbon emissions of an enterprise, a computer program product and a storage medium. The present disclosure is described below through specific embodiments.

Preferably, this embodiment can be executed by the enterprise carbon emission prediction device disclosed in the present invention. Figure 1 As shown, Figure 1 The method of the embodiment may include at least one of steps 1 to 3.
[0069] Step 1: Pre-establish a data relationship model between the carbon emissions of the enterprise's production process and the total carbon emissions of the enterprise.

[0072] In some embodiments of the present disclosure, the carbon dioxide emissions are carbon dioxide emission equivalents, which include common greenhouse gases such as carbon dioxide, methane, nitrous oxide, hydrofluorocarbons, perfluorocarbons, sulfur hexafluoride and nitrogen trifluoride. The carbon dioxide equivalent is obtained by multiplying the greenhouse gas with the corresponding global warming potential.
[0073] In some embodiments of the present disclosure, step 1 may include: constructing a carbon emission conversion model, establishing a data relationship model between the total carbon emissions of the product production and manufacturing process and the total carbon dioxide emissions within the enterprise's operating boundaries, that is, a relationship model between the carbon emissions caused by the main energy consumption in the production process and the total carbon emissions of the enterprise, which is used to form a functional relationship between the total carbon emissions and the carbon emissions of the main energy.
[0074] In some embodiments of the present disclosure, step 1 may include: performing data fitting based on historical data of carbon emissions from the enterprise's production process and the enterprise's total carbon emissions to determine the data relationship model.

[0079] In some embodiments of the present disclosure, carbon emissions include carbon emissions from the product manufacturing process and the total carbon dioxide emissions within the enterprise's operating boundaries. The carbon emissions from the production process are the direct or indirect carbon emissions caused by the consumption and use of energy such as electricity, natural gas, steam, acetylene, propane, diesel, gasoline, etc. required for product manufacturing, and the total carbon dioxide emissions within the discrete factory operating boundary include all energy, non-energy consumption and direct carbon emissions required for activities.

[0081] In some embodiments of the present disclosure, step 13 may include: the total carbon emissions generated by the enterprise's operating scope have a nonlinear relationship with the total carbon emissions generated by the energy consumed in the product production process. Based on the generated data on carbon emissions from the product production process over the years and the total carbon emissions of the enterprise, a data relationship model between the total carbon emissions data of the product production process and the total carbon dioxide emissions within the enterprise's operating boundary is established using the least squares method, as shown in formula (1).
