Description

Technical Field

[0001] The present application relates to the field of carbon emission accounting, and in particular to a method, medium and system for calculating emissions from the entire supply chain of oyster products. Background Art

[0002] Seafood is a vital source of protein for humans, and oysters are a key shellfish resource, accounting for approximately 8% of China's total aquatic product. The entire oyster supply chain involves oyster breeding, processing and packaging, transportation, sales, and consumption, each of which generates varying degrees of carbon emissions, though specific data is unavailable.

[0003] Existing research has largely focused on carbon emissions accounting for specific processes or types of seafood, lacking a systematic accounting approach for the entire oyster supply chain. Traditional carbon emission accounting methods, such as life cycle assessment (LCA) and input-output analysis, pose challenges when applied to the entire supply chain of specific seafood products like oysters, including oysters. This is particularly true given the diverse farming practices and significant regional variations of oysters, making it difficult for existing general methods to accurately reflect the carbon emissions characteristics of the entire supply chain.

[0004] Therefore, developing a carbon emission calculation method applicable to the entire supply chain of oyster products has important theoretical and practical value for accurately assessing the carbon footprint of the oyster industry, formulating effective emission reduction strategies, and promoting the green transformation of the industry.

[0044] Furthermore, based on the national oyster supply-demand ratio, the actual oyster demand in each province can be further determined. When , it means that the supply exceeds the demand. The supply of oysters can meet the demand of oysters in each province. Calculate; when When , it means that the supply is insufficient to meet the demand of each province. At this time, the demand of each province can be multiplied by the current The product of the two is taken as the actual demand for oysters.

[0045] S103, calculate the carbon emissions from breeding and aquaculture based on national oyster production.

[0046] In some embodiments, the carbon emissions from breeding and farming are calculated using the following formula:

[0047] in, Indicates carbon emissions from breeding (unit: ton), Indicates the national oyster production (unit: tons), Represents the carbon emission coefficient of breeding and aquaculture.

Although Liaoning, Jiangsu, Zhejiang, and Hainan also produce oysters, calculations show that the demand for oysters in these four provinces exceeds their own supply, requiring them to rely on supplies from Fujian, Shandong, Guangdong, and Guangxi.

[0053] Therefore, during transportation, the shortest distance is followed. The oyster production in Liaoning, Jiangsu, Zhejiang, and Hainan provinces is all used for their own needs. The transportation distance within the province is calculated according to the following formula:

[0054] in, Indicates the transportation distance within the province (unit: km), Indicates the area of ​​the current province (unit: km²).

[0055] The transportation distance from oyster-supplying cities to oyster-demanding cities can be further calculated through the inter-provincial transportation planning model.

[0056] As an example, you can use the Pulp Python library for planning and solving.

[0057] Preferably, first, define the distance dictionary, the distance between provinces; then, define the oyster demand of each province; then, define the oyster quantity of the oyster supply province; then, define the transportation quantity variable and the objective function.

[0058] Specifically, the objective function can be defined as:

[0059] in, Indicates the transportation distance from the supply province to the demand province, Represents the demand for oysters in the demanding province.

[0060] Then, define the constraints:

[0061]

[0062] The above constraints mean that the total transport volume of each demand province is equal to its oyster demand; the total transport volume of each supply province does not exceed its oyster supply.

[0063] In this way, the oyster transportation distance, transportation tonnage and transportation times can be solved.

[0068] in, represents the carbon emissions from the oyster consumption process (unit: ton), Indicates the Oyster demand in each province (in tons), represents the carbon emission coefficient of natural gas, Indicates the carbon emission coefficient of the induction cooker, Indicates the carbon emission coefficient of charcoal barbecue.

[0069] As an example, first, for the carbon emission coefficients of oysters at different stages, the values ​​in Table 2 can be preferably used as the basis: Carbon emission coefficient of the oyster industry chain Coefficient (tons of CO2 / ton of oysters) Breeding and farming carbon emission coefficient (A) 0.0707 Carbon emission coefficient of processing and packaging (B) 0.0356 Carbon emission coefficient of transport refrigerant leakage (C) 0.00019 Diesel combustion carbon emission coefficient (D) 0.00263 Carbon emission coefficient of refrigerator electricity consumption (E) 0.0227 Carbon emission coefficient of refrigerator refrigerant leakage (F) 0.0006216 Natural gas carbon emission coefficient (G) 0.432 Induction cooker carbon emission coefficient (H) 0.326 Carbon emission coefficient of charcoal barbecue (J) 0.896 Table 2 Among them, the carbon emissions from breeding and aquaculture are calculated using the following formula:

[0070] in, Indicates carbon emissions from breeding (unit: ton), Indicates the national oyster production (unit: tons), Represents the carbon emission coefficient of breeding and aquaculture.

[0071] The carbon emissions from processing and packaging are calculated using the following formula:

[0072] in, Indicates the carbon emissions from processing and packaging (unit: ton), Indicates the Oyster demand in each province (in tons), Indicates the carbon emission coefficient of processing and packaging.

[0073] The carbon emissions from the oyster sales process are calculated using the following formula:

[0074] in, represents the carbon emissions from the oyster sales process (unit: tons), Indicates the Oyster demand in each province (in tons), Indicates the carbon emission coefficient of the refrigerator's electricity consumption, Indicates the carbon emission coefficient of refrigerator refrigerant leakage.
