Abstract : *(250~1000 words)

China is a major shipping country in the world, and carbon emissions from shipping should not be underestimated. With the implementation of future strategies such as strong transportation, strong maritime power and transportation restructuring, China's ship activities will further increase. Doing a good job of ship carbon emission control is one of the work to promote China's carbon neutrality and emission peak. And mapping the emission base is an important foundation to carry out a series of carbon emission control work. This study summarizes a variety of accounting methods for ship carbon emission inventory, including total energy consumption accounting method, single voyage energy consumption accounting method and turnover accounting method, etc. The calculation principle, calculation formula, data acquisition way and method characteristics of each method are given, and the comparison and analysis are carried out from several levels, such as data demand, application, result form and method operation difficulty, etc., and the ship The method of carbon dioxide emission accounting is recommended under different situations and conditions. In addition, this study proposes a high-precision AIS-based ship CO2 emission inventory accounting method, and gives the calculation principle, calculation formula, values of several key parameters such as emission factors, data acquisition methods and method features of the method. Compared with the traditional accounting method, this method can provide more detailed calculation results for ship type, ship tonnage and shipping area, which can more effectively support systematic, scientific and refined management of pollution reduction and carbon reduction, and help China's carbon neutrality and emission peak.
