Research on calculation of oceangoing vessels turnover under the background of carbon peak

Abstract

The global ecological environment is facing great pressure. In recent years, China has continuously promoted the process of green development, and put forward the goal of carbon peak and carbon neutralization. Transportation industry is one of the important sectors of carbon emissions, and the measurement of carbon emissions is also a concern of the world. The turnover of ship transportation is the basis for the measurement of carbon emissions in the shipping industry. But, the measurement of carbon emissions from water transportation industry is not complete. There is a lack of statistics on the turnover of oceangoing ships sailing along the coast. This creates obstacles for China to accurately reduce carbon emissions. Therefore, it is very important and necessary to calculate the turnover of oceangoing ships sailing along the coast. This has also become the focus of this study. This paper constructs a route network model. Based on ship berthing data, the coastal transportation turnover of ocean-going ships is calculated. This paper selects five typical routes and three key areas as the research objects. According to the characteristics of navigation, the international container ship is calculated. By analyzing the key indicators such as the number of ships, the number of cargoes, the number of port of call, and the coastal navigation distance, the turnover of ships on each route in the year is calculated. Accordingly, in 2020, oceangoing ships turnover in China's coastal transport is 957 billion tons of kilometers, accounting for 9.4 % of China's waterway transport turnover.
