Carbon-emission and Cost-benefit Analysis of Beibu Gulf Port Integrated Logistics Services

To promote the green and low-carbon transformation of Beibu Gulf Port, this paper systematically analyzes the content composition, cost-benefit factors, carbon emissions of Beibu Gulf Port's integrated logistics services. It calculates the carbon emissions of port's integrated logistics services from the five aspects of transportation means, machinery and equipment, material consumption, energy consumption and other factors, and develop the carbon-emission and cost-benefit linkage model by combining the cost-benefit factors. The case analysis results indicate that, Qinzhou Port need to plant more than 29.76 million trees to achieve the goal of carbon emission reduction annually. Its transportation vehicle carbon emissions and costs are much higher than that of other parts. It is suggested to improve the port comprehensive benefits by increasing the electric power ratio of transportation vehicles or reducing the conversion standard coal coefficient of electric energy appropriately.
