Pushing cruising forward
When it comes to reducing CO2 emissions and reaping economic savings, a multitude
of solutions are available. In the case of Carnival Corporation, it is the increasing use of liquefied natural gas in company ships. Martin Morris speaks to Tom Strang, senior vice- president of maritime affairs at Carnival Corporation, who explains the benefits of this solution and how it will help the company meet its long-term objectives.
arnival’s AIDA Cruises launched its first liquefied natural gas (LNG) cruise ship in 2018, providing confirmation that the company was taking its CO2 emissions output very seriously. This

was underscored when Carnival’s Italian-branded Costa Cruises took delivery of its first LNG-powered ship, the Costa Smeralda, in 2019. And in December 2021, its second LNG ship, the Costa Toscana, followed. Tom Strang, senior vice-president of maritime affairs at Carnival Corporation, is also taking the CO2
emission
issue seriously as he oversees the company’s long-term objective to reduce its carbon footprint. For example, its 2030 goal, aligned with that of the International Maritime Organisation, is to reduce carbon emissions by 40%. Carnival also intends on achieving net carbon-neutral ship operations by 2050.
Meeting key objectives
Central to realising these objectives has been an expansion of the company’s alternative fuel strategy
across its LNG programme. As well as battery, fuel cell and biofuel capabilities, the aim is to deliver a 50% reduction in absolute air emissions (of particulate matter) by 2030, relative to a 2015 baseline. And this is despite a more than 10% increase in capacity since 2015, as well as the factoring in of an additional 19% capacity currently on order.
An odourless, colourless, non-toxic gas, LNG is the cleanest burning fossil fuel available. Indeed, when compared with traditional ship fuel (marine diesel), the reduction in CO2 emissions is significant.

LNG also eliminates nearly all particulate emissions (like soot) and sulphur oxide emissions, benefiting the environment and the sea air that passengers breathe while on board, according to Strang. With four LNG-powered cruise ships currently in operation, Carnival intends on having a grand total
