Description

Technical Field

[0001] This invention relates to the field of carbon cost accounting technology, and more specifically, to a method, system, and electronic device for carbon cost accounting throughout the product lifecycle. Background Technology

[0002] Driven by the "dual carbon" goals, enterprises face the dual challenges of carbon emission management and cost accounting: 1. Deficiencies in traditional cost accounting: Existing financial systems only account for explicit production costs (raw materials, labor, equipment), failing to include implicit environmental costs (such as carbon quota purchase fees and the potential impact of carbon tariffs), leading to product pricing deviating from true social costs (e.g., a car manufacturer failed to account for carbon emissions in its supply chain, resulting in 12% of its actual carbon costs going unrecognized). 2. Fragmented carbon footprint tracking: Most enterprises can only account for carbon emissions in the production process (e.g., factory energy consumption), lacking full-chain coverage of upstream raw material mining (e.g., carbon emissions from steel smelting) and downstream logistics recycling (e.g., product waste disposal), resulting in "gaps" in carbon data. 3. Insufficient ESG (Environmental, Social, and Governance) decision support: The economic benefit assessment of emission reduction schemes (e.g., switching to low-carbon packaging, investing in photovoltaic equipment) relies on qualitative analysis, lacking quantitative tools (e.g., the difference in the marginal contribution of different emission reduction schemes to products cannot be accurately measured).

[0003] Among related technologies, carbon footprint accounting faces the following technical bottlenecks: 1. Fragmented data across the entire lifecycle: Data from the procurement end (supplier carbon performance) and the recycling end (reverse logistics carbon emissions) are not integrated, and the accounting boundary is limited to within the enterprise; 2. Lack of financial conversion of carbon costs: The mapping relationship between carbon quotas, carbon taxes and product costs has not been established (e.g., the specific impact of the EU carbon border tax on the cost of exported products cannot be quantified); 3. Simplified decision-making model: Only carbon footprint reports are provided, without linking financial indicators (such as marginal contribution and net profit), which cannot support the economic comparison of emission reduction schemes.

[0004] Therefore, a method for calculating the carbon cost of a product throughout its entire life cycle is needed. Summary of the Invention

[0072] Exemplary methods

[0073] Figure 1 This is a flowchart illustrating a product lifecycle carbon cost accounting method 100 according to an exemplary embodiment of the present invention. The method of this embodiment can track the carbon footprint of a product throughout its entire lifecycle, providing core technological support for enterprises' sustainable development in a carbon-neutral context, and possesses significant technological innovation and industry application value. This embodiment can be applied to electronic devices, such as... Figure 1 As shown, it includes the following steps:

[0074] In step 101, the carbon emissions of the product at different stages of its life cycle are obtained based on the carbon emission factors of the product at different stages of its life cycle.

[0075] Preferably, the different life cycle stages include: procurement, production, logistics, use, and recycling.

[0076] Preferably, obtaining the carbon emissions of a product at different stages of its life cycle based on carbon emission factors at different stages of the product's life cycle includes:

[0077] In the procurement process, the carbon emissions from procurement are determined based on the formula: "Procurement carbon emissions = Procurement quantity × Unit carbon emission factor".

[0078] In the production link, the production carbon emissions are determined based on the formula "Production carbon emissions = Equipment energy consumption × Electricity carbon emission factor + Scrap treatment volume × Scrap carbon emission factor".

[0079] In the logistics link, the logistics carbon emissions are determined based on the formula "Logistics carbon emissions = Obtained weight × Transportation distance × Carbon intensity factor".

[0080] In the usage link, the usage carbon emissions are determined based on the formula "Usage carbon emissions = Driving mileage × Unit power consumption × Electricity carbon emission factor".

[0081] In the recycling link, the recycling carbon emissions are determined based on the formula "Recycling carbon emissions = Scrap disposal volume × Treatment emission factor - Recycled material volume × Material production emission reduction factor".

[0082] In the embodiments of the present invention, data is collected from five dimensions of procurement, production, logistics, usage, and recycling and the carbon emissions are calculated.

[0083] Specifically, in the procurement link, it is connected to the supplier system, blockchain nodes are deployed, and the supplier raw material carbon emission data is obtained through blockchain technology, and the procurement carbon emissions are calculated. Among them, the procurement carbon emissions are determined based on the formula "Procurement carbon emissions = Procurement volume × Unit carbon emission factor". For example, steel smelting carbon emissions = Procurement volume (tons) × Unit carbon emission factor (such as 2.3 tons CO2e / ton of steel). In addition, it can also require the supplier to upload data in an associated manner according to "Product - Raw material - Carbon emission" to generate a "carbon traceability file" in association with the procurement order.

[0084] Specifically, in the production link, edge computing gateways are deployed on equipment such as injection molding machines and lathes, the energy consumption data and scrap treatment carbon emission factors are collected on a second-by-second basis, and the production carbon emissions are determined based on the formula "Production carbon emissions = Equipment energy consumption × Electricity carbon emission factor + Scrap treatment volume × Scrap carbon emission factor". For example, if the electricity carbon emission factor is 0.8 kgCO2e / kWh, the scrap carbon emission factor is 0.5 kgCO2e / kg, the injection molding machine consumes 50 kWh of electricity in 1 hour, and the scrap is 30 kg, then the production carbon emissions can be determined as 50×0.8 + 30×0.5 = 55 kgCO2e.

[0085] Specifically, in the logistics link, it is connected to the transportation management system TMS, the carbon intensity factor is calculated according to the transportation mode (sea / air / land transportation) (such as 0.15 tons CO2e of emissions per ton of goods per kilometer for sea transportation), and then the logistics carbon emissions are determined based on the formula "Logistics carbon emissions = Obtained weight × Transportation distance × Carbon intensity factor". For example, for 10 tons of goods transported by sea for 1000 kilometers, the logistics carbon emissions = 10×1000×0.15 = 1500 kgCO2e.

[0086] Specifically, during the usage phase, energy consumption is collected through product network data (such as the carbon emissions corresponding to the electric vehicle's driving range) or user surveys. The carbon emissions are then determined based on the formula: "Usage carbon emissions = Driving distance × Unit energy consumption × Electricity carbon emission factor". For example, taking an electric vehicle as an example, with a unit energy consumption of 0.15 kWh / km and an electricity carbon emission factor of 0.8 kg CO2e / kWh, driving 1000 km would result in usage carbon emissions of 1000 × 0.15 × 0.8 = 120 kg CO2e.

[0087] Specifically, in the recycling stage, recycling IoT tags (such as RFID UHF tags) are deployed to record the disposal process (dismantling and recycling stages). The amount of carbon emissions recovered is determined based on the formula: "Recovered carbon emissions = Disposal volume × Disposal emission factor - Recycled material volume × Material production emission reduction factor". For example, if the disposal emission factor is 0.3 kg CO2e / kg and the material production emission reduction factor is 2.0 kg CO2e / kg, and 100 kg of lithium batteries are recycled and 50 kg are reused, then the recovered carbon emissions = 100 × 0.3 - 50 × 2.0 = -70 kg CO2e (the negative sign indicates emission reduction).

[0088] In embodiments of the present invention, a product carbon footprint database can also be constructed based on the LCA (Life Cycle Assessment) standard, and five-dimensional data can be integrated by SKU (such as a certain type of cable) to generate a "full life cycle carbon emission inventory".

[0089] In step 102, the carbon cost factors for different life cycle stages are determined.

[0090] Preferably, determining the carbon cost factor for different life cycle stages includes:

[0091] Carbon cost factors for different lifecycle stages are determined based on carbon allowance costs, carbon taxes, and carbon removal costs.

[0092] In embodiments of this invention, carbon allowance costs (e.g., a local carbon trading market price of 80 yuan / ton CO2e), carbon taxes (e.g., the EU carbon tax of 100 euros / ton CO2e, equivalent to 780 yuan / ton), and carbon removal costs (e.g., CCUS technology costs of 200 yuan / ton CO2e) are integrated to form a dynamically updated cost factor library (synchronized with carbon market data monthly). Different cost factors can be configured for different stages; for example, the production stage can be prioritized with carbon taxes as a carbon cost factor, while the logistics stage can be prioritized with carbon allowances as a carbon cost factor.

[0093] In step 103, the carbon emission cost of each life cycle stage is determined based on the carbon emission amount of each life cycle stage and the corresponding carbon cost factor.

[0094] Preferably, the carbon emission cost for each life cycle stage is determined based on the carbon emissions at each stage and the corresponding carbon cost factor, including:

[0095] For any lifecycle stage i, based on "H i =T i ÷1000×S i The method for determining carbon emission costs is as follows:

[0096] Among them, H i The carbon emission cost of any life cycle stage i; T i S represents the carbon emissions at any stage i in the life cycle; i Let i be the carbon cost factor corresponding to any life cycle stage i.

[0097] In step 104, the total carbon emission cost is determined based on the sum of the carbon emission costs of each life cycle stage.

[0098] In embodiments of the present invention, the carbon emission cost of each stage is obtained by multiplying the carbon emission amount of each stage by the corresponding carbon cost factor and dividing by 1000, i.e., based on "H i =T i ÷1000×S i The carbon emission cost is determined in a way that allows H to be used as an indicator; among which, H i The carbon emission cost of any life cycle stage i; T i S represents the carbon emissions at any stage i in the life cycle; i Let i be the carbon cost factor corresponding to any life cycle stage i.

[0099] Taking the procurement process as an example, the carbon emission cost of procurement = carbon emission amount procured (kgCO2e) ÷ 1000 × carbon quota price (yuan / tonCO2e). For example, if the carbon emission amount procured is 230 kgCO2e, then the carbon emission cost of procurement = 230 ÷ 1000 × 80 = 18.4 yuan.

[0100] In embodiments of the present invention, the sum of the carbon emission costs of each stage is the total carbon emission cost.

[0101] Preferably, the method further includes:

[0102] The carbon emission costs and total carbon emission costs for each stage of the life cycle are presented according to different dimensions.

[0103] In embodiments of this invention, a BI dashboard (such as Power BI or Tableau) is developed to display carbon cost distribution across multiple dimensions: "product-process-cost type," supporting drill-down analysis (e.g., drilling down from "total carbon cost" to "carbon cost of a specific SKU's production process"). Visualized indicators include: a carbon cost percentage pie chart (the proportion of carbon cost at each stage to the total carbon cost); a carbon cost trend line chart (monthly / quarterly carbon cost changes, compared to changes in business volume); and a carbon cost heatmap (displaying carbon cost density by SKU / product line, identifying high-carbon products).

[0104] Preferably, the method further includes:

[0105] Determine the carbon cost objective function and business constraints, and use linear programming or genetic algorithms for optimization to optimize all stages of the product lifecycle;

[0106] The carbon cost objective function is to minimize the total cost of carbon emissions; the business constraints include production scale constraints, supply chain cycle constraints, and carbon emission reduction constraints.

[0107] In embodiments of the present invention, carbon cost optimization decisions can also be made. Specifically, based on linear programming (LP) or genetic algorithm (GA), the inputs are "carbon cost target (e.g., a 10% reduction)" and "business constraints (e.g., production scale, supply chain cycle)", and the outputs are optimization solutions (e.g., replacing low-carbon suppliers, adjusting transportation methods, improving production processes).

[0108] The decision-making model includes the following: the objective function is MinΣ(carbon cost at each stage), and the constraints are: 1. Production scale constraint: output ≥ market demand (e.g., 1000 units / month); 2. Supply chain cycle constraint: for example, procurement-production-logistics cycle ≤ 30 days; 3. Carbon emission reduction constraint: for example, total carbon emissions ≤ baseline value × (1-10%).

[0109] In embodiments of the present invention, data can be re-collected and carbon costs calculated quarterly based on the optimization scheme output by the decision model (such as replacing supplier A with low-carbon supplier B) to verify the optimization effect (such as a 15% reduction in carbon procurement costs after replacement), forming a closed loop of "optimization-verification-re-optimization".

[0110] The advantages of this invention are:

[0111] 1. Full lifecycle coverage: Accounting for the entire chain from procurement to recycling, adapting to the carbon neutrality "full life cycle emission reduction" requirements, and ensuring that no carbon costs are overlooked.

[0112] 2. Deep integration of business and finance: Convert carbon emissions into financially quantifiable costs (such as carbon tax and carbon quotas) to solve the pain point of "difficulty in financializing environmental costs" under the carbon neutrality goal.

[0113] 3. Dynamic optimization: Through decision-making models and closed-loop management, carbon costs are continuously reduced, helping enterprises achieve the dual goals of "cost reduction + emission reduction" in the context of carbon neutrality, and meeting ESG compliance requirements.
