9 DIARIO DEL PUERTO MIÉRCOLES 10 SEPTIEMBRE 2025 in ports significantly reduces emissions and points to the “availability of renewable fuels” as key to decarbonization. “Cruise lines are innovative and early adopters of new technologies, investing billions of dollars to build the future of sustainable travel on today’s ships,” CLIA notes. Regarding renewable fuels, the International Cruise Lines Association highlights the need for governments to “support research and other efforts to accelerate the development of renewable fuels so that they are safe, viable, and available on a large scale.” Concrete progress Over the past year, there have been some important milestones in the adoption of renewable or sustainable fuels by various cruise lines. One example of these milestones is the first refueling of liquefied natural gas (LNG) for the Costa Esmerald, the flagship of the Costa Cruceros fleet, in Dubai. This operation was the first LNG supply to a cruise ship in that location. In this regard, Costa Cruceros pointed out that LNG is currently “the best and most suitable fuel available to achieve an immediate reduction in greenhousegases intheabsence of fuels ready for the zero-emission market in the maritime industry.” The company indicated that LNG is considered the leading fossil fuel because, in addition to reducing direct carbon emissions byup to 20%, it completely avoidsemissionsofnitrogenoxide, sulfur oxide, and particulate matter. “Liquefied Natural Gas enables aviable steponthepath to net-zero emissions from ship operations by 2050,” Costa Cruceros emphasizes. tualmente “el mejor y más preparado combustible disponible para conseguir una inmediata reducción de gases de efecto invernadero ante la ausencia de combustibles preparados para el mercado de cero emisiones en la industria marítima”. La compañía indicó que el GNL está considerado el principal entre los combustibles fósiles porque, además de reducir las emisiones directas de carbono hasta un 20%, evita totalmente las emisiones de óxido de nitrógeno, óxido de sulfuro y partículas. “El Gas Natural Licuado permite un paso viable en Costa Cruceros apunta al GNL como el combustible con mayor disponibilidad en la actualidad para reducir emisiones. / Costa Cruceros is focusing on LNG as the most readily available fuel currently available for reducing emissions.
