Greener on the High Seas: Carnival Advances Climate Goals

But how exactly is this ambitious goal being achieved? Carnival relies on a mix of new, highly efficient ships and clever technology. Older vessels are being retired, while the newest fleet members are equipped with shore power capabilities and modern LNG (liquefied natural gas) propulsion systems. Furthermore, neat tricks like a carpet of tiny air bubbles under the hull help reduce water resistance. All of this not only saves energy but also shields the company from strict and costly European Union environmental penalties.

However, amidst all this enthusiasm, there is a slight catch. The corporation’s goals always refer to emissions per passenger. This means: Because the cruise industry continues to boom and increasingly larger ships are being built, the absolute overall CO2 footprint still rises. Furthermore, the use of LNG is not without controversy, as its combustion results in "methane slip," which harms the climate in a different way. Carnival currently rejects absolute emission reduction targets, simply because the necessary, truly green alternative fuels are not yet available in sufficient quantities worldwide.

In summary, Carnival Corporation is accomplishing genuine engineering feats to make its own ships as clean and efficient as possible. This is an important step in the right direction, significantly driven by strict European regulations. However, it will likely take a few more years before we can cruise completely climate-neutral and without a guilty conscience. The ultimate challenge remains making alternative fuels universally accessible for all ships in the future.
