Specific embodiments

[0018] The present invention will be further described below through specific embodiments.

[0019] The present invention proposes a carbon emission and carbon footprint measurement method for industrial enterprises. A carbon footprint accounting model is established according to the correspondence between products and carbon emission sources for the product manufacturing process, so as to solve the problem of inaccurate carbon footprint accounting of products during the manufacturing process and realize data traceability at the same time.

[0020] Such as Figure 1 A carbon emission and carbon footprint measurement method for industrial enterprises according to the solution of the present invention; specifically includes the following steps: S101: Determine a carbon emission correspondence model according to the collected product information and production information of industrial enterprises, where the production information includes raw material information, process information, and production equipment information; Specifically, the carbon emission correspondence model includes a determined carbon emission model and a variable carbon emission model.

[0021] Determined carbon emissions: refer to the carbon emissions generated by some energy consumption in an enterprise that do not change due to the type and quantity of products produced, such as lighting facilities, ventilation facilities, etc., which are called fixed carbon emissions; Variable carbon emissions: refer to the carbon emissions generated by energy consumption in an enterprise that are closely related to the type, quantity, processing method, etc. of the products produced, such as equipment power consumption, coolant use, etc. The processing difficulty and quantity of products will directly affect the amount of carbon emissions, which are called variable carbon emissions.

[0022] The carbon footprint of product manufacturing represents the sum of carbon emissions during the manufacturing process of the product, including carbon emissions generated from electricity consumption, workpiece material loss, coolant consumption, lubricant consumption, waste chip treatment, wastewater treatment, etc. in the manufacturing process. However, due to the wide variety of products in manufacturing enterprises, it is difficult to accurately calculate the carbon footprint of each product's manufacturing process. Therefore, the calculation method proposed in the present invention is to analyze the corresponding relationship between the carbon emissions of each link in the product manufacturing process and the product, calculate the carbon emissions of the product in each link of the manufacturing process according to different corresponding relationships, and finally sum them up to obtain the carbon footprint of the product's manufacturing process.
