Abstract
This paper considers the influence of different carbon emission policies for liner shipping. The transportation optimization models under four different forms of carbon emission policies (no carbon emissions constraints, carbon emissions tax, carbon caps, and carbon cap-and-trade) are developed. A real case is given to demonstrate the effectiveness of the proposed models and comparative analysis of the impact of different carbon emission policies on shipowner’s profit and ship carbon emission. It is shown that the carbon caps form is the most direct method for reducing emission; the form of carbon emissions tax is a mandatory measure, which has the greatest impact on the profit of shipping companies; carbon cap-and-trade forms have weaker emission reduction effects, it is easier for enterprises to actively implement emission reductions and be highly motivated in the long run.
Highlights
Carbon emission control policies will affect the speed decision, which is closely related to the optimization of liner transportation [1]
In July 2011, at the 62nd meeting of the Marine environmental protection committee, International Maritime Organization (IMO) adopted the VI amendment to the annex to the international convention for the prevention of pollution from ships, the first mandatory law and regulation related to carbon emission reduction applicable to ships of all countries
We adopt the following methodological steps as summarized below: (i) Constructing the optimal decision model of liner transportation based on the profit of the shipping company by using the fuel consumption law of the host, regardless of the carbon emission policy (ii) Using the relationship between fuel consumption and carbon emissions, construct a liner transportation optimization decision model that considers carbon emissions tax, carbon caps, and carbon cap-and-trade (iii) The model was verified by the real case of COSCO (China Ocean Shipping (Group) Company) SHIPPING Lines Co., Ltd. and the results were discussed and analyzed
Summary
Carbon emission control policies will affect the speed decision, which is closely related to the optimization of liner transportation [1]. IMO has developed the concept of a Sustainable Maritime Transportation System for the “safe, secure, efficient and reliable transport of goods across the world, while minimizing pollution, maximizing energy efficiency and ensuring resource conservation” [9] In this context, it is more practical to study the issue of shipping carbon emissions. (i) Constructing the optimal decision model of liner transportation based on the profit of the shipping company by using the fuel consumption law of the host, regardless of the carbon emission policy (ii) Using the relationship between fuel consumption and carbon emissions, construct a liner transportation optimization decision model that considers carbon emissions tax, carbon caps, and carbon cap-and-trade (iii) The model was verified by the real case of COSCO (China Ocean Shipping (Group) Company) SHIPPING Lines Co., Ltd. and the results were discussed and analyzed Under this context, the purpose of this paper:.
