heal.abstract	The decarbonization of shipping as part of a global strategy to mitigate climate change is the dominant issue in the shipping industry nowadays. In this context, the International Maritime Organization (IMO) recently adopted new regulations aimed at reducing emissions per transport work, including the Carbon Intensity Indicator regulation. This thesis intends to examine the impact of the CII regulation on the existing fleet of Liquefied Natural Gas Carriers. The study is based on the calculation of the Carbon Intensity Indicator for a share of the existing fleet of LNG Carriers using operational data from the MRV system for the year 2020. As the exact form of the regulation after 2026 is unknown, the compliance of vessels with the regulation until 2030 is examined by developing some trajectory scenarios. The study is conducted on a generalized fleet level as well as by categorizing the fleet based on size, age, and propulsion type. Furthermore, the CII between similar vessels and its comparison with technical efficiency indexes are evaluated. Finally, a case study is conducted between various types of LNG Carriers and Bulk Carriers that transport coal, the major CO2 polluter and competitor of gas in the energy sector, to provide a more comprehensive perspective on the contribution of LNG in decarbonization and the role of shipping in the LNG supply chain. The aim is to compare the energy content of each cargo, as well as emissions during ship transportation and the entire lifecycle of cargo intended for power generation.	en
