Study On Container Port’s Energy Structure Based On Life-cycle Theory

China’s port cargo throughput and container throughput have ranked first in the world for nine consecutive years. Container port plays a positive role in promoting the rapid development of urban economy and even the development of the regional economy. However, as an energy guzzler, it inevitably causes energy consumption and greenhouse gas emissions. The development of low-carbon container port is imminent. Currently, there are very little existing relevant research and application, limited to qualitative description. They just proposed the necessity of developing a low-carbon container port and development goals, without quantifying the concept of low-carbon. The research on the combination of life cycle theory and low-carbon container port is very little, and cannot control container port’s low-carbon from the source.In this context, on the basis of the life-cycle theory, this paper conducted a comprehensive study and analysis of the full life cycle of the port, combining the characteristics of the coastal container ports; respectively explored energy use characteristics of the port at different stages in the life cycle; from the actual situation, through a large number of data collection, statistics and analysis, quantified the energy consumption and carbon emissions of the port at different stages in the life cycle and proposed theoretical formula; finally, tested the validity and practicality of the conclusions of this study through a case study. The research results show that the conclusion of the study presented in this paper is reasonable and effective, which can provide theoretical reference for the quantitative description of the container port’s carbon emissions.
