International trade is becoming more and more vigorous. In recent years, the shipping industry has gradually come out of the doldrums, continues to develop steadily, and the number of ships is also rising. Today, ship exhaust pollution has become one of the main causes of air pollution. According to the International Maritime Organization (IMO), from January 2020, the sulfur content of ship fuel in sulfur emission control zones is less than 0.1%, and the sulfur content of ship fuel in non-control zones is less than 0.5%. There are currently three mainstream countermeasures; 1. Low-sulfur fuel technology; 2. LNG replacement technology; 3. Exhaust gas treatment technology. This article analyzes the average annual cost of two of these options, and analyzes which one is more suitable for the development of the shipping industry.
