Description

Technical Field

[0001] The present invention relates to the technical field of carbon footprint accounting, and in particular to a carbon footprint accounting system and method for marine ranches. Background Art

[0002] Marine ranching is an emerging ecological aquaculture model that aims to achieve sustainable fishery development by integrating the development of marine biological resources with ecological protection through scientific and rational human intervention and resource utilization. Within this model, marine ranching is endowed with an important carbon sink function. By cultivating species such as fish, shellfish, and algae, marine ranching can absorb and fix large amounts of carbon dioxide through natural processes such as photosynthesis and biorecycling, thereby playing a positive role in mitigating global climate change. However, existing research and technologies primarily focus on the carbon sequestration capacity of marine ranching, while accounting for its carbon footprint over its entire life cycle remains significantly insufficient.

[0003] Currently, most research on carbon emissions and carbon sequestration in marine ranches focuses on the following aspects:

[0004] Carbon sequestration capacity assessment: Studies have shown that algae and shellfish in marine ranches have significant carbon sequestration capacity. By biologically absorbing and storing carbon dioxide, these species can capture atmospheric carbon in a short period of time. However, these studies are often limited to specific species or single ecosystems.

[0005] Carbon emissions during the construction phase: Some studies have recognized the carbon emissions associated with the construction of marine ranches, such as those from the production and transportation of building materials like concrete piles and steel. However, these studies have mostly focused on emissions during the construction phase, failing to incorporate them into analyses of the entire life cycle.

[0006] Energy consumption during the operational phase: The daily operations of marine ranches require energy, such as using diesel generators to power farm equipment and maintaining them. This energy consumption results in significant carbon emissions, but existing research on this phase remains fragmented, lacking a systematic accounting method.

[0007] Although existing research has explored carbon emissions and carbon sequestration in marine ranches in some aspects, from a full life cycle perspective, these technologies have the following major shortcomings:

[0008] Lack of full-lifecycle carbon footprint accounting: Existing technologies are often limited to analyzing carbon emissions or carbon sequestration during a single phase (such as construction or farming), while ignoring the interconnectedness between different phases. For example, high-carbon-emitting materials used during the construction phase can significantly impact a ranch's long-term carbon neutrality goals, while energy consumption during operations and maintenance can also put ongoing pressure on total carbon emissions. The failure to systematically calculate carbon footprints from a full lifecycle perspective has led to incomplete research conclusions.

[0009] Lack of dynamic accounting and forecasting capabilities: Existing technologies typically calculate carbon emissions or carbon sequestration based on static data, failing to fully account for temporal changes. For example, the carbon sequestration capacity of farmed species may decline over time, while carbon emissions during the operational phase may also change due to equipment aging or technological improvements. The lack of dynamic forecasting models makes it impossible to accurately assess the carbon balance of marine ranches over the next few decades.

[0010] Lack of correction mechanisms: Existing research relies on a single accounting method, lacking the ability to dynamically adjust to actual operational data. For example, prediction model results are often based on assumptions, while actual operations may be subject to fluctuations in fuel usage, changing climate conditions, and other factors. This lack of dynamic adjustment can lead to significant deviations between carbon footprint accounting results and actual conditions.

[0011] Lack of a comprehensive accounting system: Existing technologies typically calculate carbon emissions and carbon sequestration separately, focusing on a single objective. For example, accounting only measures the carbon sequestration capacity of fish or carbon emissions at a specific stage, while ignoring the combined impacts of other species and stages. This fragmented accounting approach hinders comprehensive carbon footprint assessments and fails to provide scientific support for managers' carbon neutrality decisions.

[0012] Lack of standardized reporting output: Existing technologies lack unified standards for presenting accounting results, making it impossible to form standardized carbon footprint reports. For example, they fail to output annual carbon emission trends, total carbon sequestration, and carbon neutrality target recommendations throughout the entire life cycle. This makes it difficult for accounting results to be widely used by policymakers, managers, or researchers.

[0013] Therefore, we urgently need to design a carbon footprint accounting system and method for marine ranches to solve the above problems. Summary of the Invention

[0061] 3. The report generation module of the present invention can output full-life cycle carbon emissions and carbon fixation trend charts, carbon neutrality target recommendations, and key carbon management indicators, solving the problem of non-standardized accounting results and limited application value in existing technologies. Through standardized and visual reporting formats, the system can provide intuitive data support for policymakers and managers, helping them to scientifically plan marine ranch construction and operation strategies and promote the realization of their carbon neutrality goals. This standardized output format significantly enhances the value of the system in practical applications and expands the ecological and economic benefits and social influence of marine ranches.

[0089] Report generation module: outputs carbon emissions E(t) and carbon fixation F(t) for the entire life cycle, and provides trend analysis and carbon neutrality achievement recommendations for the next 30 or 50 years.

[0090] Second, the following several embodiments are used for detailed description;

[0091] Example 1: Calculation of the carbon footprint of the entire life cycle of marine ranching;

[0092] Data collection during the construction phase:

[0093] Material: Steel M1 = 1000lg, Carbon emission factor C m,1 =1.8lgCO2 / kg; cement M2 = 500lg, carbon emission factor Cm ,2=0.9kerCO2 / kg.

[0094] Data collection during the operation phase:

[0095] Fuel: Diesel F1 = 200lg, carbon emission factor C f,1 =3.1kerCO2 / kg;

[0096] Electricity: Consumption E1 = 1000kWh, carbon emission factor C e,1 =0.5kgCO2 / .

[0097] Data collection during the breeding phase: Breeding species: fish A1 = 100m 2 , growth rate G1 = 50kg / year, carbon fixation factor CF1 = 2.5kgCO2 / kg

[0098] Carbon emissions during the construction phase:

[0099] E construction =M1×C m,1 +M2×C m,2 =1000×1.8+500×0.9=1800+450=2250kgCO2;

[0100] Carbon emissions during the operation phase:

[0101] E operation =F1×C f,1 +E1×C e,1 =200×3.1+1000×0.5=620+500=1120kgCO2;

[0102] Carbon fixation from aquaculture:

[0103] F total =A1×G1×CF1=100×50×2.5=12500kgCO2;

[0104] Carbon emissions throughout the entire life cycle:

[0105] E total =E construction +E operation =2250+1120=3370kgCO2;

[0106] Carbon footprint calculation results: carbon fixation is much greater than carbon emissions, indicating that pastures have a significant carbon absorption effect.

[0107] Example 2: Life cycle prediction and correction;

[0108] Current carbon emissions E current =3370kgCO2, current carbon fixation Fcurrent =12500kgCO2;

[0109] Annual growth rate R growth =0.02, annual decay rate R decay =0.01.

[0110] Forecast of carbon emissions in 10 years: E future( 10 ) =3370× ( 1+0.02 ) 10 =3370×1.219=4108.03kgCO2;

[0111] Predicted carbon sequestration in 10 years: F future( 10 ) =12500× ( 1-0.01 ) 10 =12500×0.904=11300kgCO2.

[0112] Actual monitoring value: Actual carbon emissions E after 10 years actual =4200kerCO2, actual carbon fixation F actual =11200kgCO2;

[0113] Correction value:

[0114] ΔE=E predicted -E actual =4108.03-4200=-91.97kgCO2;

[0115] ΔF=F predicted -F actual =11300-11200=100kgCO2;

[0116] Result: The revised prediction is closer to the actual situation and the model accuracy is improved.

[0117] Example 3: Comprehensive calculation of the carbon sequestration capacity of multiple aquaculture species in marine ranches;

[0118] Data collection: Farming species 1: Fish area A1 = 200m 2 Growth rate G1 = 50 kg / year, carbon fixation factor CF1 = 2.5 kgCO2 / kg;

[0119] Cultured species 2: Seaweed area A2 = 300m 2 Growth rate G2 = 20 kg / year, carbon fixation factor CF2 = 1.8 kgCO2 / kg;

[0120] Cultured species 3: Shellfish population A3 = 5000; individual growth rate G3 = 0.3 kg / year; carbon fixation factor CF3 = 0.8 kg CO2 / kg;

[0121] Carbon fixation by fish:

[0122] F1=A1×G1×CF1=200×50×2.5=25000kgCO2;

[0123] Seaweed carbon fixation:

[0124] F2=A2×G2×CF2=300×20×1.8=10800kgCO2;

[0125] Shellfish carbon fixation: F3 = A3 × G3 × CF3 = 5000 × 0.3 × 0.8 = 1200 kg CO2;

[0126] Total carbon fixation: F total =F1+F2+F3=25000+10800+1200=37000kgCO2;

[0127] The carbon fixation capacity of the marine ranch species is 37,000 kg CO2.

[0128] If combined with the emissions from the carbon emission accounting module, the overall carbon footprint can be further calculated.

[0129] Example 4: Predicting and adjusting the carbon balance of ocean ranches over the next 50 years;

[0130] Initial data: Current carbon emissions E current =5000kerCO2; Current carbon fixation F current =20,000kgCO2; annual growth rate of carbon emissions R growth =0.03; annual carbon fixation decay rate R decay =0.01;

[0131] Forecasting carbon emissions over the next 50 years: E future (50) = E current ×(1+R growth ) 50 ;

[0132] E future (50) = 5000 × (1 + 0.03) 50 =5000×4.384=21920kgCO2;

[0133] Forecasting carbon sequestration over the next 50 years:

[0134] F future( 50 ) =Fcurrent × ( 1-R decay) 50

[0135] F future( 50 ) =20000× ( 1-0.01 ) 50 =20000×0.605=12100kgCO2;

[0136] Correction: Actual monitoring data:

[0137] Carbon emissions E actual =23000kgCO2;

[0138] Carbon fixation F actual =11800kgCO2;

[0139] Correction value:

[0140] ΔE=E predicted -E actual =21920-23000=-1080kgCO2;

[0141] ΔF=F predicted -F actual =12100-11800=300kgCO2.

[0142] After the correction, future trends in carbon emissions and carbon sequestration need to be readjusted to optimize the carbon neutrality strategy of the ranch.

[0143] In summary, through the above examples, carbon sequestration will decrease by 39.5% in the next 50 years, and measures need to be taken to improve the carbon sequestration capacity of farmed species.

[0144] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein.
