Why has the world's largest cruise liner become a target for environmentalists?

This is a testament to human ingenuity and extravagance. Stretching almost 365 meters in length and with 20 decks for loading its passengers, the Icon of the Seas is a floating metropolis. 2,805 staterooms and an impressive array of 40 restaurants: with a capacity to host nearly 10,000 passengers and crew, this mammoth vessel promises a gigantic experience of opulence and leisure on the high seas.

Despite its grandeur, the Icon of the Seas has not escaped scrutiny. Critics underscore its environmental impact, labeling it an “anti-environmental monstrosity”. They raise concerns about its carbon footprint and the sustainability of such flamboyant ventures at a time increasingly defined by environmental consciousness.

LNG in the spotlight

Indeed, the Icon of the Seas, registered in the Bahamas, marks the debut of the American cruise company into liquefied natural gas (LNG) propulsion. While the industry touts LNG as a cleaner substitute for heavy fuel oil, it's important to note that LNG releases methane, a potent greenhouse gas.

Environmentalists then remain skeptical of the industry's reliance on LNG as an effective and cleaner alternative to traditional marine fuels. While LNG emits fewer pollutants than conventional fuels, concerns persist regarding the environmental impact of developing LNG as a standard.

According to experts, LNG could exacerbate climate change if not managed effectively. Several NGOs argue that the proliferation of LNG-powered vessels would reinforce the further exploitation of fossil fuel reserves, perpetuating our dependence on environmentally harmful energy sources.

Also, NGOs add that port overcrowding and inadequate infrastructure pose significant challenges for destinations hosting these maritime giants. The influx of thousands of passengers strains local resources and infrastructure, prompting calls for greater collaboration between cruise lines and port authorities to address these issues.

Renewed popularity for cruises

Yet, despite the controversy, the Icon of the Seas symbolizes the cruise industry's resilience and resurgence following the tumultuous years of the COVID-19 pandemic. As the world gradually emerged from lockdowns and travel restrictions, the leisure cruise sector is witnessing a gradual enthusiasm to travel more.

According to the Cruise Lines International Association (CLIA), passenger volumes in 2023 surpassed pre-pandemic levels, with a bit less than 31.5 million passengers sailing away. One thing is for sure: travelers are back to the decks of luxury liners, breathing new life into an industry that faces a lot of challenges.

Advocates of this trend cite economic efficiencies and technological advancements as driving forces behind the construction of mega-ships. Meyer Turku, the shipyard responsible for its construction, has two other vessels of similar size in its order book, revealing the growing demand for larger-than-life maritime experiences.

"Larger vessels offer economies of scale, reducing the cost per passenger and enhancing profitability for cruise operators", replied one of the company's managers to its detractors. "Moreover, sophisticated engineering enables these ships to navigate the world's oceans with unparalleled efficiency and safety.”

In the hope of maintaining ever-increasing occupancy rates, the cruise industry stands at a crossroads, balancing economic imperatives with environmental stewardship and passenger comfort. As the Icon of the Seas embarks on its first voyage, it embodies both the promise and perils of maritime travel in the 21st century.
