Roadmap for the Decarbonization of Domestic Passenger Ferries in the Republic of Korea

This study examines the steps to lower air emissions in South Korea’s domestic shipping sector. It highlights the significant contributions of the sector to air pollution and greenhouse gas emissions, emphasizing its impact on environmental sustainability and climate change mitigation. By looking at the current shipping energy use and emissions, the research identifies ways to reduce the environmental impact of domestic shipping. Data was collected from domestic ferry routes and the fuel use was reviewed with respect to existing global technologies for reducing emissions. The results show that operational changes and current energy-efficient technologies can quickly cut emissions. Furthermore, a long-term plan is suggested, involving the development of new ship designs and the use of net-zero fuels like biofuels, methanol, hydrogen and ammonia. These efforts aim to meet climate goals, targeting a 40% reduction in greenhouse emissions by 2030 and a 70% reduction by 2050, making South Korea’s shipping industry more sustainable and resilient.
