Description

Technical Field

[0001] This invention relates to a system for assisting enterprises in declaring carbon tariffs, and more particularly to a carbon tariff calculation method and service system that utilizes computer methods and links to external information. Background Technology

[0002] Greenhouse gases (GHGs) are gases that can absorb and re-radiate infrared radiation emitted by the Earth's surface. Major greenhouse gases include carbon dioxide (CO2), methane (CH4), nitrous oxide (N2O), hydrofluorocarbons (HFCs), perfluorocarbons (PFCs), sulfur hexafluoride (SF6), and nitrogen trifluoride (NF3). The increase in these gases is primarily due to human activities, such as fossil fuel combustion, industrial production, and agricultural activities, leading to global warming, extreme weather events, and sea-level rise, which have serious impacts on humans and ecosystems.

[0003] The United Nations has called for urgent carbon reduction actions, and "net zero carbon reduction" has become a common global issue. International organizations have further proposed net zero standards, aiming to limit global warming to a certain range (such as within 1.5°C). Furthermore, in order to effectively control industrial carbon emissions, in addition to implementing greenhouse gas inventory and formulating carbon reduction strategies, countries and international organizations have also proposed carbon tariffs.

[0004] For example, the EU's Carbon Border Adjustment Mechanism (CBAM) mandates that goods exported from member states to the EU must share the carbon reduction costs with EU manufacturers. Specifically, regulated high-carbon-emission goods require CBAM certificates for export to the EU. Certain goods require CBAM certificates to enter the EU, and these certificates are a practical application of carbon tariffs. For instance, initially, the EU mandated that steel, cement, fertilizers, aluminum, electricity, and hydrogen, among other related goods, declare their carbon emissions when imported into the EU. This allowed for the calculation of carbon costs, resulting in carbon tariffs on imports into the EU. Summary of the Invention

[0005] In order to provide services for enterprises and manufacturers to calculate carbon tariffs when exporting goods to countries (including the European Union) that impose carbon tariffs on goods, this disclosure proposes a carbon tariff calculation method and service system using computer and network communication technologies.

[0006] According to an embodiment, the service system for calculating carbon tariffs includes a computing circuit, a storage module, and a communication module, and also includes an enterprise operation and sales database. The service system connects to the enterprise database and the carbon tariff and regulatory database through the communication module.

[0007] The carbon tariff calculation method operates within a service system. In this method, the service system retrieves enterprise operational and sales data from the enterprise database to obtain the quantity of exported products, carbon footprint, and carbon emissions. It then incorporates the carbon tariff regulations of the importing country of the exported products, including the carbon credit price and levied items, as well as the tax exemption allowance. Finally, it obtains the amount of tax already paid by the enterprise. This allows the service system to calculate carbon tariffs based on product quantity, carbon emissions, carbon credit price, tax exemption allowance, and paid tax, and to create a report on the carbon tariff declarations for enterprises exporting products to the importing country.

[0008] Furthermore, the service system can obtain the carbon credit price, tax exemption amount, and carbon footprint tax items of the importing country from external systems, thereby calculating carbon tariffs and generating a report on the carbon tariffs declared by the enterprise for its exported products to the importing country.

[0009] Furthermore, within the service system, the carbon footprint of a company's exported products can be obtained through carbon inventory. This involves allocating organizational greenhouse gases across all stages—raw material acquisition, production and manufacturing, distribution and sales, product use, and waste recycling—according to an energy resource use allocation principle. The entire range of organizational greenhouse gases encompasses direct greenhouse gas emissions, energy-related indirect greenhouse gas emissions, and other indirect greenhouse gas emissions.

[0010] According to an embodiment of the carbon tariff calculation method, the carbon tariff is equal to the carbon emissions of the product multiplied by the carbon credit price, and then multiplied by the quantity of the product.

[0011] Furthermore, the service system can obtain the import duty-free allowances and carbon credit prices from the importing country's carbon tariff and regulatory database via an application programming interface (API). The service system further connects to a product carbon footprint system via its respective API to obtain the product's carbon footprint; a business operations and sales data system to provide business operations and sales data; a system of carbon tariff regulations, industries, products, and raw materials for each country to obtain carbon tariff regulations for each country, including various tax codes for taxable products; a system of carbon tariff levies for each country to obtain taxable items for different countries; a system of carbon tariff duty-free allowances for each country to obtain different duty-free allowances set by each country for different products; a local carbon credit price system for each country to obtain the carbon credit prices set by each country; and a system of carbon prices already paid for each exporting country to obtain the amount of tax already paid by the company in the location where the product is manufactured.

However, the drawings provided are for reference and illustration only and are not intended to limit the present invention. Attached Figure Description

[0019] This disclosure proposes a carbon tariff calculation method and a service system for operating carbon tariff calculation. The service system realizes carbon tariff calculation services for enterprises through the collaboration of computers, software and networks. Through its software functions, it obtains the carbon footprint of products based on information provided by enterprises, and combines the enterprise's operating and sales data, the differences in carbon tariff items (HS Code or NAICS) of various countries, the differences in product carbon footprint items, the differences in carbon tariff exemption amounts, and the differences in local carbon credit prices to simulate and calculate the enterprise's operating carbon tariff. The calculated carbon tariff can also be imported into the enterprise's profit and loss statement (P&L).

[0020] Based on the technical objective of using computer technology to calculate carbon tariffs proposed in this disclosure, and with the increasing awareness of the value of carbon internationally, several countries, including the EU's Carbon Border Adjustment Mechanism (CBAM) and the US Clean Competition Act (CCA), have proposed legislation involving carbon tariffs since 2023. Due to the complexity and frequent changes of these projects, the need for evolving legal regulations, and the staffing requirements of general enterprises, this invention provides a solution for enterprises that need to simulate and calculate carbon tariffs. It can address issues such as the shortage of professional personnel, monitoring carbon border tariff laws and changes in various countries, and monitoring changes in local carbon credit prices. Furthermore, the results of simulation and calculation can be imported into the enterprise's profit and loss statements.

[0021] The service system for running the carbon tariff calculation method is implemented through the collaboration of computer technology, the software programs running within it, and network technology. (See reference...) Figure 1 The diagram shows an example of a service system.

[0022] The service system 100 shown in the diagram includes a computer system that assists enterprises in calculating carbon tariffs. The computer system has major hardware components such as an arithmetic circuit 101, a storage module 103, and a communication module 105, and can collaborate with the software components in the service system 100 to achieve the purpose of calculating carbon tariffs. The service system 100 uses software and storage devices to implement an enterprise operation and sales database 107, which stores enterprise operation and sales data 171 obtained from the enterprise, carbon tariff regulations 173 obtained from external systems for various countries, carbon footprint tax items 175 for products from various countries (referring to the importing countries of the enterprise's exported products), carbon weight prices 177 for various countries, and fees already paid by each exporting country 179 provided by the enterprise.

[0023] According to the embodiment, the service system 100 mainly provides a filtering mechanism for various complex information of enterprises. It can easily filter information such as carbon tariff regulations 173 of various countries, carbon footprint tax items 175 of products, and carbon credit prices 177 according to needs. Based on the enterprise's operating and sales data 171 provided by the enterprise, including the export products and the import destinations of the products to be exported, plus the enterprise's direct and indirect carbon emission list, and the information such as the fees paid by the enterprise in each export country 179, the computing circuit 101 calculates the carbon tariffs of the products exported to various places.

[0024] It is worth mentioning that enterprises will conduct carbon inventories by collecting data through questionnaires and other methods to obtain information on organizational greenhouse gas emissions and product carbon footprints. According to the example, the relevant questionnaires can be implemented using carbon asset management reports, such as those generated using Microsoft... Design reports to conduct carbon audits on companies' exported products. Regarding the EU Carbon Border Adjustment Mechanism, as shown in Table 1, the relevant fields of the company's operational and sales data to be obtained include: production process, type of aggregated good or precursor, CN Codes, CN Name, product name, direct SEE, indirect SEE, total SEE, unit (e.g., metric tonnes of CO2 equivalent), share of emissions by default value, and source for electricity emission factor (EF).

[0025] Table 1:

[0026]

[0027]

[0028] Thus, the service system 100 uses software methods to connect to enterprise database 111 and enterprise database 2 112 via network 10, based on the enterprise's needs (exported products and import destinations), using communication module 105 to obtain various enterprise operational and sales data 171 that can be used to determine the carbon footprint of products. For example, enterprise database 111 and enterprise database 2 112 can be used to obtain information such as the enterprise's work order production information, production material list or material requisition list, sales records, greenhouse gas inventory data, and supplier carbon coefficients. For example, Tables 2 and 3 record work order production information and lists of production materials or materials requisitioned, and Table 4 records the carbon emissions and carbon coefficients of the raw materials themselves; it can also obtain relevant data on organizational greenhouse gas inventory as recorded in Table 5, thereby calculating the carbon emissions and coefficients allocated to the process from specific emission sources; the emission sources of products manufactured in the enterprise are exemplified in Table 6; then, the service system 100 can also assign different allocation principles to the selected emission sources, such as volume allocation, weight allocation, processing time allocation, and quantity allocation, etc., and the allocation criteria setting examples can be found in Table 7.

[0029] Finally, in the service system 100, an enterprise operation and sales database 107 can be established based on the enterprise operation and sales data 171 provided by the enterprise as shown in the example above, and the carbon footprint of the product can be calculated based on the allocation settings and carbon coefficients, as shown in Table 8.

[0047] The enterprise operations and sales database 107 also includes external systems connected to the service system 100 via network 10 and communication module 105, such as obtaining carbon tariff regulations 173, product carbon footprint levy items 179, and carbon credit prices 177 from the carbon tariff and regulations database 115 through an application programming interface (API). Subsequently, based on whether a specific product is subject to carbon tariffs according to the energy resource use allocation guidelines (based on HS codes), the product carbon footprint can be obtained only for products subject to tariffs.

[0048] In this way, the service system 100 can learn from the above-mentioned enterprise operation data which countries the enterprise's products are to be exported to. It can then filter out the taxable items and emission sources by querying the items subject to carbon tariffs in each country, and add the carbon credit price of each country (each country has a corresponding server to provide a query of carbon credit price, query the items and prices already taxed in each country) and the tax exemption quota, which is the so-called carbon leakage exposure factor.

[0049] The service system 100 obtains information that may dynamically change or be revised at different stages by connecting to external systems (such as the carbon tariff and regulation database 115 shown in the above embodiment). In particular, each country sets different carbon tariff items, carbon credit prices, and tax-free prices, which can be referenced. Figure 2 The diagram shows an embodiment of the connection relationship between the service system and external systems proposed in this disclosure.

[0050] like Figure 2 The system 100 connects to external systems via a network and an application programming interface (API), enabling it to obtain various information related to calculating carbon tariffs and perform complex calculations and simulations of carbon border tariffs for business operations. The external system can be implemented by servers containing publicly available data from various governments and server systems built by various enterprises. Based on the various types of data provided, it can be divided into: a product carbon footprint system 201, which obtains the product carbon footprint; an enterprise operation and sales data system 202, which can be stored in various enterprise systems to provide enterprise operation and sales data; a carbon tariff regulations, industry, product, and raw material system 203, which obtains carbon tariff regulations from various countries, including various tax codes for taxable products, such as the globally used HS Code, and can correspond to the EU import tariff code (CN Code); a carbon tariff levy item system 204, which obtains the taxable items in different countries; a carbon tariff exemption system 205, which obtains the different exemption limits set by various countries for different products; a local carbon weight price system 206, which obtains the unique carbon weight price set by each country; and a carbon price already paid system 207 for each exporting country, which obtains the tax amount already paid by the enterprise in the location where the product is manufactured, which can be used to reduce carbon tariffs after export to the importing country.

[0051] When calculating carbon tariffs on products exported by enterprises to various importing countries, it is necessary to obtain the carbon footprint of each product during the preliminary work. (Refer to...) Figure 3 The diagram shows an example of a process in the carbon footprint of a product within the company's operational and sales data.

[0052] A product's complete carbon footprint should include at least the production stage (raw materials and processing), transportation, use, and waste recycling, and implement measures such as... Figure 3 The system shows that the carbon footprint of a company’s exported products is obtained through carbon inventory. In this process, greenhouse gases are allocated to the raw material acquisition stage 31, the production and manufacturing stage 32, the distribution and sales stage 33, the product use stage 34, and the waste recycling stage 35, based on the energy resource use allocation criteria.

[0053] The carbon footprint of the raw material acquisition stage 31 is formed by carbon emissions generated during the raw material acquisition stage 31, the main raw material manufacturing stage 311 and the main raw material produced stage 312, the auxiliary raw material manufacturing stage 313 and the auxiliary raw material produced stage 314, the packaging manufacturing stage 315 and the packaging produced stage 316, and the processes after the production of raw materials, such as raw material transportation and waste disposal stage 36, including wastewater and waste gas.

[0054] The carbon footprint of the manufacturing stage 32 is formed by the generation of carbon emissions during the production and manufacturing phase 32, including material feeding 321, and various processes such as process one 322 and process two 323 as shown in the figure, as well as subsequent packaging 324, storage 325 and shipping 326, and subsequent transportation process and wastewater and waste gas treatment 36.

[0055] In the distribution and sales phase 33, the transportation of packaged products to distributors / distributors 331, including the waste disposal 36 of waste packaging materials generated at distributors / distributors 331, all contribute to the carbon footprint of the distribution and sales phase 33 due to carbon emissions.

[0056] During the consumer's product use phase 34, the product is delivered to the consumer. Because the consumer uses it 342, energy is used 341, generating waste packaging materials 343. In the final product disposal and recycling phase 35, energy resources 351 are used for waste recycling 352. Carbon emissions are generated in all these processes, forming the product's carbon footprint.

[0057] However, in different countries, carbon tariffs are levied on the carbon footprint of specific stages, processes, and the corresponding products of direct or indirect carbon emissions at each stage.

[0058] Figure 4 The following is a schematic diagram illustrating the data relationship between organizational greenhouse gas inventory categories and product carbon footprint stages, which can be applied to the calculation of carbon tariffs.

[0059] This example shows that carbon inventory information 40 includes a full range of organizational greenhouse gas emissions, covering Scope 1: direct greenhouse gas emissions, Scope 2: energy-related indirect greenhouse gas emissions, and Scope 3: other indirect greenhouse gas emissions. Based on the greenhouse gas emissions defined in each scope, the corresponding organizational greenhouse gas inventory and the corresponding product carbon footprint are then derived.

[0060] For details regarding each category, please refer to the text in the diagram. Category 1 includes 1.1 direct emissions from stationary combustion sources, 1.2 direct emissions from mobile combustion sources, 1.3 direct process emissions and removal from industrial processes, 1.4 direct temporary emissions of greenhouse gases released by anthropogenic systems, and 1.5 direct emissions and removal from land use, land use changes, and forestry. Category 2 includes 2.1 indirect emissions from electricity input and 2.2 indirect emissions from energy input. Category 3 includes 3.1 emissions generated from upstream transportation and distribution of goods (Scope 3-4), 3.2 emissions generated from downstream transportation and distribution of goods (Scope 3-9), 3.3 emissions generated from employee commuting (Scope 3-7), 3.4 emissions generated from transporting customers and visitors, and 3.5 emissions generated from business travel (Scope 3-6). 5.1 emissions or removal generated during the production and use phase (Scope 3-11), 5.2 emissions generated from downstream leased assets (Scope 3-13), 5.3 emissions generated during the end-of-product life cycle (Scope 3-12), and 5.4 emissions generated from investments (Scope 3-12). 3-15), emissions from the processing of products sold (Scope 3-10), and franchising (Scope 3-14); and 6.1 indirect greenhouse gas emissions.

[0061] During the carbon inventory process, a corresponding carbon footprint is formed based on the greenhouse gases generated at each stage and category of product manufacturing. According to the illustrated embodiment, the service system can allocate the carbon inventory information 40, such as the total greenhouse gases across all categories, to the corresponding stages of product manufacturing based on an energy resource use allocation criterion 41. For example, comparing... Figure 3 Show implementation examples, Figure 4 The displayed product carbon footprint stages include the raw material acquisition stage 43, the production and manufacturing stage 44, the distribution and sales stage 45, the product use stage 46, and the waste recycling stage 47, to achieve the purpose of carbon inventory.

[0062] The carbon tariff calculation method is executed through the service system described in the above embodiments. For further details, please refer to the method embodiments. Figure 5 The flowchart shown.

[0063] The service system obtains the company's operational and sales data, from which it derives product carbon emissions and related information, including the quantity of exported products, carbon footprint, and product carbon emissions (step S501). It then imports carbon tariff regulations from external systems, particularly those of the importing countries of the company's exported goods (step S503), and also imports carbon footprint levy items from various countries (step S505) to obtain tax exemption allowances (step S507) and carbon credit prices (step S509). It also retrieves the amount of taxes already paid by the company in each country from its financial statements (step S511). Thus, the service system creates a report on the company's declared carbon tariffs for exported products to the importing country based on the product quantity, carbon emissions, carbon credit price, tax exemption allowance, and taxes already paid (step S513), and then submits the declaration to the importing country and calculates the carbon tariff (step S515).

[0064] In step S513 of establishing the carbon tariff declaration form, according to the embodiment, the pre-declaration instructions for the EU carbon tariff declaration form include a table of contents, a user guide and a code list. The main contents to be filled in include manufacturer information, manufacturer emission source data, emissions and energy, production process, purchased precursors, tools and advanced guidance, as well as data to be explained to the declarant, including a summary of process, a summary of products and a summary of communication.

[0065] In step S515, carbon tariffs are calculated based on the enterprise's operational and sales data provided by the enterprise, as well as the carbon credit price, tax exemption allowance, and product carbon footprint tax items obtained from external systems in the importing country. One embodiment of calculating carbon tariffs can refer to the formula of the EU Carbon Border Adjustment Mechanism (CBAM).

[0066] According to the EU's carbon border adjustment mechanism, it is necessary to obtain the embedded emissions of greenhouse gases during the production process of a product, that is, the carbon emissions described by carbon dioxide (CO2) or the carbon dioxide equivalent (CO2e) of related greenhouse gases, including both direct and indirect emissions. (If compared...) Figure 3The carbon footprint of a product is described as the carbon emissions from raw materials and processing during the production phase. Carbon tariffs, such as CBAM certificates, require the calculation of specific embedded emissions (SEE), which refers to the amount of carbon dioxide equivalent contained in each ton of a specific product. The calculation of carbon emissions first distinguishes between simple goods and complex goods.

[0067] The specific carbon emissions for simple goods are shown in Formula 1, where SEE g AttrEm represents the carbon emissions (tCO2e / t) of a specific product. g This indicates the amount of carbon emissions generated during the production of goods; carbon emissions (AttrEm) g This includes direct carbon emissions (DirEm) and indirect carbon emissions (IndirEm), as well as AL. g Indicates the quantity of goods produced (can be in tons).

[0068] Formula 1:

[0069] SEE g =AttrEm g / AL g .

[0070] The specific carbon emissions for complex cargo are shown in Formula 2, where SEE g AttrEm represents the carbon emissions (tCO2e / t) of a specific product. g EE represents the carbon emissions generated from the production of goods, including both direct carbon emissions (DirEm) and indirect carbon emissions (IndirEm). InpMat This represents the total carbon emissions contained in the raw materials used during the production process, as shown in Formula 3, and AL. g This represents the quantity of goods produced (in tons). In Formula 3, M represents the raw material; the purpose is to calculate the quantity of the i-th raw material (M). i ) to the nth raw material (M) n The total carbon emissions contained in ( ).

[0071] Formula 2:

[0072] SEE g =[AttrEm g +EE InpMat ] / AL g .

[0073] Formula 3:

[0074]

[0075] Once a specific amount of carbon emissions is calculated using Formula 1 or Formula 2 above, a carbon tariff can be calculated. In practice, such as the Carbon Border Adjustment Mechanism (CBAM) certificate implemented by the European Union, the carbon tariff is equal to the embedded emissions of the product multiplied by the carbon price, and then multiplied by the quantity of the product.

[0076] Furthermore, the number of CBAM certificates can represent the carbon tariff that an enterprise must pay when entering an importing country (such as a specific country or the EU) from an exporting country (such as the enterprise's location). This can be referred to in Formula 4, where the obligation amount mentioned is the CBAM obligation, which is the carbon tariff after the enterprise has fulfilled its declaration obligation upon entering the EU. This is calculated by subtracting the carbon fee already paid by the enterprise in the exporting country (or production location) to obtain the adjusted carbon tariff for entering an importing country (such as the EU).

[0077] Formula 4:

[0078] [(Actual carbon emissions from production) - (Tax exemption allowance)] × (Total imports) × (Weekly average carbon credit price) = (Obligation amount); and

[0079] (Obligation amount) - (Carbon fee already paid in the exporting country) = (Adjustment amount).

[0080] The adjustment amount refers to the carbon tariff that a company should pay when exporting products to the importing country (in this case, the EU). Under the EU Carbon Border Adjustment Mechanism, the number of CBAM certificates that the company should bear will be calculated.

[0081] For example, product A has an actual emission of 10 tCO2 / ton; the EU grants product A a free emission allowance of 2 tCO2 / ton, the average weekly carbon credit price is €50 / tCO2, and the exporting country does not levy a carbon fee (0 euros / tCO2). If 5 tons of product A are imported from the EU, the carbon tariff payable on imported product A from the EU is:

[0082] (1) Number of CBAM certificates for product A = (actual emissions - EU free emission allowances for related products) × total imports = (10-2) × 5 = 40 CBAM certificates;

[0083] (2) CBAM obligation for product A = CBAM voucher quantity × weekly average carbon credit price = 40

[0084] ×50 = 2000 euros;

[0085] (3) CBAM adjustment for product A = CBAM obligation amount - exporting country's tax paid = 2000 - 0 = 2000 euros.

[0086] Figure 6 The following is a schematic diagram illustrating an example of the service system being applied to the EU Carbon Border Adjustment Mechanism (CBAM) for declaring carbon tariffs. In this implementation example, service system 100 can be used to provide companies with the opportunity to register for the EU Carbon Border Adjustment Mechanism (CBAM) to generate declaration data for declaring EU carbon tariffs.

[0087] The European Commission has designated carbon tariff verification bodies. This example demonstrates that regulatory authority 601 is delegated to the CBAM competent authority 611 and the CBAM verification unit 613. The CBAM verification unit 613 will conduct verification 605 with manufacturers 617 who manufacture and sell products, enabling manufacturers 617 to submit requests to the carbon tariff calculation service system 100 (disclosed in this publication) to calculate carbon tariffs and generate carbon tariff declaration reports. On the other hand, the review of relevant application data 603 will be carried out by the CBAM competent authority 611 and the CBAM registration system 615.

[0088] Manufacturer 617 requests service system 100 to calculate carbon tariffs and generate a carbon tariff declaration report. According to the above-described method embodiment for calculating carbon tariffs, a CBAM report can be established, in which manufacturer 617 submits declaration data. The data, as described in the above embodiment, should include the total emissions from product imports, carbon emissions from the CBAM product, product size, equipment carbon emissions, direct and indirect carbon emissions, and manufacturing methods and qualification parameters. Optional fields may include the manufacturer of the manufacturing equipment, information on the manufacturing equipment, supporting documents for carbon emissions, and the amount of carbon tax already paid. The carbon tariff payable upon the product's entry into the EU is then calculated.

[0089] After the relevant declaration data is generated by the service system 100, the declaration data 607 is submitted to the CBAM registration system 615 by a legally authorized CBAM declarant 619 who is qualified to declare in the CBAM registry. After the application data is reviewed, the carbon tariff declared by the manufacturer 617 can be reviewed by the CBMA competent authority 611.

[0090] In summary, to help businesses navigate the complexities and evolving regulations of various countries imposing carbon tariffs on imported goods more easily, this disclosure proposes a carbon tariff calculation method and a service system for implementing this method. According to the above embodiments, the service system provides businesses with information on their product carbon footprint and carbon emissions. By obtaining carbon credit prices, tax exemptions, and already paid taxes from external systems through the service system, the carbon tariff payable by the business on its exported products is calculated. Given the varying regulations across countries, the complexity of tax items, and the constantly changing carbon credit prices, the service system, based on its ability to calculate the product's carbon footprint, enables businesses to systematically calculate the carbon tariffs on their exported products.

[0091] The above-disclosed content is only a preferred and feasible embodiment of the present invention, and is not intended to limit the scope of the patent application of the present invention. Therefore, all equivalent technical changes made based on the content of the present invention specification and drawings are included in the scope of the patent application of the present invention.
