Abstract

A carbon tariff calculation method and a service system (100). The service system (100) that runs the carbon tariff calculation executes the carbon tariff calculation method through a computing circuit (101). Enterprise operation and sales data (171) is obtained from an enterprise database to obtain a product quantity, a carbon footprint, and product carbon emissions of an enterprise export product. Then, carbon tariff regulations (173) of an import location that the enterprise export product is imported to are introduced, including obtaining a carbon credit price (177) and tax items of the import location. Simultaneously, a tax exemption quota of the import location is introduced, and an amount of a paid tax of the enterprise can be obtained. A carbon tariff is calculated based on the product quantity, the product carbon emissions, the carbon credit price (177), the tax exemption quota, and the paid tax, and a carbon tariff declaration report is created.

Description

FIELD OF THE INVENTION The present invention relates to a system that assists enterprises in carbon tariff declaration, and more particularly to a carbon tariff calculation method and service system implemented by using computer and connecting external information. BACKGROUND OF THE INVENTION Greenhouse gas (GHG) refers to a gas that can absorb and re-radiate infrared radiations emitted from the surface of the earth. Greenhouse gas mainly includes carbon dioxide (CO2), methane (CH4), nitrous oxide (N2O), hydrofluorocarbons (HFCs), perfluorocarbons (PFCs), sulfur hexafluoride (SF6), nitrogen trifluoride (NF3), etc. The increase of these gases is mainly a result of human activities such as burning fossil fuel, industrial manufacturing, and agricultural activities that lead to global warming, extreme weather events, rising sea levels, etc., which can cause serious impact on humanity and the ecosystem. The United Nations has called for immediate action on carbon reduction, and "net-zero carbon reduction" has become a common global topic. International organizations have further provided net-zero standards, with the aim of limiting global warming to be within a certain range (such as within 1.5°C). Furthermore, in order to effectively control industrial carbon emission, in addition to implementing greenhouse gas inventory and formulating carbon reduction strategies, various countries or international organizations have also provided carbon tariff measures. For example, the "Carbon Border Adjustment Mechanism (CBAM)" implemented by the EU stipulates that goods exported to the EU from various countries must bear the cost of carbon reduction together with EU manufacturers. Further, regulated high carbon emission products need to obtain CBAM certificates before they can be exported to the EU, and specific products need to have CBAM certificates purchased before entering the EU, in which CBAM certificates are an implementation of carbon tariffs. For example, in the early stages of implementing CBAM, the EU will require steel, cement, fertilizers, aluminum, electricity, hydrogen, and other related commodities to declare product carbon emissions when the commodities are imported into the EU, such that the carbon costs that are incurred can be calculated, thereby forming the carbon tariffs for importing to the EU. SUMMARY OF THE INVENTION In order to provide a service of calculating carbon tariff for enterprises and manufacturers exporting products to countries (including the European Union) that collect carbon tariff on products, the present invention provides a carbon tariff calculation method and a service system that are implemented by using computers and network communication technology. According to one embodiment, the service system executing a carbon tariff calculation includes a computing circuit, a memory module, a communication module, and an enterprise operation and sales database. The service system (i.e., the computer system) is connected to an enterprise database and a carbon tariff and regulations database through the communication module. The carbon tariff calculation method is executed in the service system. In the method, the service system obtains enterprise operation and sales data from the enterprise database to obtain a product quantity, a carbon footprint, and product carbon emissions of an enterprise export product, introduces carbon tariff regulations of an import location that the enterprise export product is imported to, including obtaining a carbon credit price and tax collection items of the import location, and introduce a tax exemption quota of the import location. Then, the service system obtains an amount of a paid tax of an enterprise. Therefore, the service system may calculate a carbon tariff based on the product quantity, the product carbon emissions, the carbon credit price, the tax exemption quota, and the paid tax, and create a carbon tariff declaration report for the enterprise export product to the import location. Furthermore, the service system can obtain a carbon credit price, a tax exemption quota, and product carbon footprint tax collection items of the import location from an external system, calculate the carbon tariff accordingly, and obtain the carbon tariff declaration report for the enterprise export product to the import location. Moreover, in the service system, the carbon footprint of the enterprise export product is obtained through carbon inventory, and a full scope of organizational greenhouse gas are allocated to a raw material acquisition stage, a production and manufacturing stage, a distribution and sales stage, a product using stage, and a product disposal and recycle stage. The full range of organizational greenhouse gases includes direct greenhouse gas emissions, energy indirect greenhouse gas emissions, and other indirect greenhouse gas emissions. According to one embodiment of the carbon tariff calculation method, the carbon tariff is equal to the prod
