Cruises, 5 ideas for more sustainable travel

A little premise: despite the green efforts made by companies in recent years, Cruise ship sustainability still has a long way to go. Indeed, judging by what guard, is still far away. in this video investigation taken from International, the English paper marshals a series of strong claims, many of which are backed up by not-so-reassuring updated data, such as: “the carbon dioxide emitted per passenger by large ships is four times that of air travel” or: “The 218 ships operating in Europe in 2022 emitted four times more sulfur oxides than all the cars on the continent”. Even LNG, the liquefied natural gas that has reduced carbon dioxide emissions so far the cleanest and most efficient marine fuel available on a large scale today – is reduced: “it would be better to use fuel cells or renewable hydrogen and methanol, which emit less greenhouse gases.”

In short, the painted by guard It looks like a situation very unstable. Still, cruise lines are announcing significant efforts on the subject: from slowing ships to plugging them into ports to switching fuels and increasing supply chain awareness. These are remarkable choices, but they represent only steps towards the future 2050the symbolic date indicated by shipowners as the year in which the net zero emissions target should be achieved, even more important if we consider that cruise traffic is increasing significantly.

I’m waiting for really green times, here are five companies that are investing in technology capable of making cruises more sustainable. For each of them we also chose a symbolic project implemented: something that, apart from technological development, has the merit of hitting public opinion and tourists in the gut, raising their awareness of the problem. It’s all a game when it comes to protecting the planet.

Norwegian Cruise Lines

The greenest and smartest ships in the fleet: the Prima class

There First grade it is the top of the line for Norwegian Cruise Lines. Ships already built belong to this special family – Norwegian prima And Norwegian Viva – are equipped with systems to reduce harmful emissions, which reduce the overall impact of the ship on the environment. On board there are catalysts that filter sulfur oxides and nitrogen oxides, advanced exhaust gas cleaning systems and waste water treatment systems. Cold Ironing technology is finally being used to connect these two marine giants to land-based power grids so as to reduce their emissions in port.

The flagship project: sustainable proteins on board

Within the framework of the global sustainability project, the so-called Sail & Sustain one chapter promotes the sustainable sourcing of chicken, eggs, pork and seafood, some of the most consumed proteins on board. The Miami-based company has updated its purchasing policy standards to favor suppliers that use cage-free confinement systems for laying hens, raise pigs without the use of gestation cages and are able to certify as sustainable the sources from which the fish comes. products. Norwegian Cruise Lines states that “by 2025, we aim to achieve 100% of these supplies made in an ethical and sustainable manner, while also promoting animal welfare.”

Royal Caribbean Group

The Destination Net Zero plan

Royal Caribbean Group, the brand that includes the Royal Caribbean, Celebrity Cruises and Silversea Cruises brands, announced a massive decarbonization plan in 2021 called Destination Net Zero, with the goal of almost completely reducing greenhouse gas emissions by 2050. To achieve this, the American cruise giant is working in its research and development laboratories to create more efficient hulls, improve energy efficiency on board, develop alternative fuels and overhauling the entire supply chain. The first net zero emission ship is expected to be launched in 2035.

The symbolic project: zero waste in the Galapagos

Silversea – Royal Caribbean Group’s luxury boutique ship brand – has activated Galapagos Conservation Project, the delicate ecosystem off the coast of Ecuador attracts cruise passengers from around the world every year. The ship covering this route, Silver originsegregates all its collection of paper, plastic, glass and other waste generated on board, then entrusts their treatment to waste management companies that use waste oil to fuel the incinerators and ensure traceable processes.

Silversea’s commitment to Galapagos sustainability extends to the culinary offerings on board Silver Origin. In recent years, in view of the supply of ingredients such as dairy products, fruits and vegetables, the company prefers farmers and independent suppliers in Santa Cruz and San Cristóbal, so as to strengthen the local economy and support ongoing conservation efforts. “The consumption of zero-kilometer products also reduces imports of products from mainland Ecuador, reducing the risk of invasive species entering the islands,” Silversea states.

Carnival Corporation

Drinking sea water on board Costa Smeralda and Costa Toscana

On Costa Smeralda and Costa Toscana – two of the most modern ships of Costa Crociere, an Italian company part of the American Carnival Corporation group – have removed almost all single-use plastic items. Even single-dose samples have been eliminated, while two-thirds of the fresh water used on board comes from the sea: it is first desalinated and then purified to make it drinkable. Both Costa Smeralda and Costa Toscana use liquefied natural gas for propulsion.

The symbolic project: the sustainable gourmet restaurant

Archipelago is a gourmet and sustainable culinary format of Costa Crociere: a restaurant – present on board six ships of the fleet – that combines design and taste with respect for the environment: for the selection of part of the furnishings, branches brought ashore by the waves and restored during of operations for the protection of the marine environment by the Costa Crociere Foundation. The menu is entrusted to three world-renowned multi-star chefs: Bruno Barbieri, Helen Darroz and Angel Leon who have created a taste journey in five courses and three different menus. The main courses? Graminha al torchio with eggplant and sausage for Barbieri; confit cod for Darroze; plankton rice for Leon.


Euribia, the greenest ship in the fleet

Over the past few years there have been numerous sustainability related declarations issued by MSC’s Italian market country manager, Leonardo Massaalmost all aimed at a concrete explanation of the green technologies adopted by the Italian-Swiss company, others at reiterating the importance of the sea for the group, others at widening the scope of the problem: “to shipowners, as well as to airlines, they are major investments necessary to address sustainability needs, and that’s right,” Massa recently clarified, “but we’re really sure that each of us, at home, is doing everything we can to reduce concretely, every day, our own impact on the environment ?”

MSC’s most sustainable ship is called Eurybia: powered by LNG and equipped with advanced wastewater treatment, waste management and seawater treatment systems. Euribia also uses innovative systems to manage the noise emitted underwater to reduce the impact on the marine environment.
