In response to global sulfur emission restrictions, China has established sulfur emission control areas in its coastal areas. This has a huge impact on China's coastal shipping ships. These ships can adopt the following three sulfur abatement options to deal with it: (1) using low-sulfur fuel, (2) using an exhaust gas cleaning system, and (3) using alternative fuel Liquefied Natural Gas (LNG). This paper has established two models from two different perspectives to analyze the differences of abatement options between the shipowners and the general public. Sensitivity analyses are carried out on the factors affecting the sulfur abatement options, including remaining lifespan of ships, ship power, initial cost of sulfur abatement options, and fluctuations in the price of fuel. By analyzing the impact of these factors on the choice of the shipowners to reduce sulfur emission, this paper proposes some incentives and subsidy policies accordingly, which can provide references for policymakers.
