Fossil fuels contribute to GHG emissions into the atmosphere. The need to solve this critical global problemhas driven the search for alternative energy options to pave the way towards a more sustainable future. Thispaper analyzes the environmental and economic performance of a small cruise ship operating in the NorthAtlantic Ocean. The paper compares natural gas-electric and hybrid propulsive configurations, considering LNGand E-LNG produced using renewable electricity. The carbon footprint analysis is based on equivalent ??_2emissions according to a Well-to-Wake approach and includes emissions of the on-shore power for batterycharging. A novel index for the energetic classification of ships is proposed, considering their equivalent ??_2emissions using a Well-to-Wake approach. The hybrid propulsive systems show a fair fuel-saving potential,ranging from 3.5% to 5.3%. The E-LNG-powered propulsion is three times more expensive than LNG, whileGHG emissions produced using E-LNG are 4.5 to 6 times lower. The battery pack is a major cost item in hybridsystems. Moreover, GHG evaluation through the novel index penalizes hybrid propulsion systems compared totraditional carbon dioxide emission assessment since the former includes ground connection used for batterycharging.
