Abstract: This study is based on detailed data from 11 sea voyages over three years to determine the impact of liquefied natural gas (LNG) use on the decarbonization pathway in maritime transportation. The research detailed the vessel's daily fuel consumption, CO2 emission inventories, and Carbon Intensity Indicator (CII). The decision tree method used to evaluate this complex dataset highlights the possible contributions of LNG to maritime energy efficiency and sustainability. While the findings show that LNG reduces CO2 emissions by around 30 %, it is insufficient to meet the International Maritime Organization's (IMO) 2050 targets. The study concludes that LNG should be an important transition fuel until the mid-2030s. However, the maritime sector needs multi-pronged strategies such as technological innovations, stringent regulations and sectoral collaborations to achieve a decarbonized future. This research provides a comprehensive analysis assessing the potential of LNG to achieve the IMO 2050 targets in the context of maritime decarbonization strategies.
