In April 2019, eight Carnival companies violated their five-year probation by dumping plastic with food waste directly into the ocean (so this wasn’t the first time they did it) according to NPR. And all ships are allowed to drop untreated sewage directly in the ocean, as long as they’re at least three miles offshore, though 90 percent of cruise lines have an agreement not to dump untreated sewage. Even still, Carnival Cruise Lines along with Crystal Cruises and Costa Cruises received “F” ratings in terms of sewage treatment from the 2019 Report Card. Large amounts of harmful gas emissions and environmental pollution can be attributed to cruise ships. This is not to mention the waste produced by passengers and the cruise industry.

The cruise industry says it's improving. But is it?

Ships with AWTS were downgraded in 2021 because no companies publicly report on the performance of those advanced systems. Ships with AWTS were downgraded in 2022 because no companies publicly report on the performance of those advanced systems. LNG use would reduce health-harming air pollution, according to the new report, but cruise ships that use it will likely leak the potent greenhouse gas methane. Findings reveal that on a seven-day trip, passengers on an Antarctic cruise can release as much carbon emissions per traveler as the average European in an entire year.

Its local rival Hurtigruten is building or converting several ships that use the technology, while in 2021 the French cruise line Ponant took delivery of its sparkling new Le Commandant Charcot, a 123-cabin ship also powered by batteries and LNG. The polar class ship sails to the geographic North Pole, Greenland, the Svalbard archipelago, the Bellingshausen Sea and the Larsen Ice Shelf. Five of its 16 ships that launched in 2022 ran on LNG, according to CLIA.

Many cruise lines claim to be taking steps towards more sustainable travel. However, not many of these cruise shipping lines are taking steps towards effecting any significant change. A large cruise ship can generate tons of waste, polluting our environment. Cruise liners have begun to reduce or ban the use of single-use plastics to reduce plastic waste. Manufacturers designed the EGCS to reduce sulfur oxide and nitrogen levels.

However, what seems like an exciting journey has a massive effect on our environment. Carnival was hit with a $40 million fine for illegal waste disposal and was put on federal criminal probation in 2017. During their five-year probationary period an independent court-ordered monitor was required to examine its ships. A year later, Carnival had to pay another $20 million for environmental violations.

Prior to the COVID-19 pandemic, millions of Americans took cruise vacations every year. Yet, most travelers didn’t realize that taking a cruise is more harmful to the environment and human health than many other forms of travel. “CLIA cruise lines are pioneers in maritime environmental protection and committed to responsible tourism – with policies that often exceed those required by law," CLIA said in a statement. FOE asserts taking a cruise can be more harmful to the environment and human health than other forms of travel.

Cruise lines have made their ships more fuel efficient by implementing a few different tactics, according to CLIA. The cruise lines that are coming to the DOJ's attention on the criminal enforcement side are in scope because something has "not gone well for them." John Kaltenstein, deputy director of oceans and vessels at FOE, said that while the industry is making some small strides, there's a long way to go. "This is certainly something that has been a focus of the cruise industry, really even the maritime industry overall," Salerno said. An international research team led the most comprehensive research review ever conducted on what was one of the fastest growing industries in tourism before the pandemic.

Finally, the last section provides recommendations on future actions needed to reduce adverse environmental burdens and impacts arising from cruise ship operations. The paper also includes research on solid waste as example of an activity from cruise ships which impacts both health and environment. Reducing plastics and marine littler are major global challenges, and a total amount of rubbish produced by a cruise ship carrying 2,700 passengers can exceed a ton per day.

Alternatively, one individual staying in a high-end hotel, using carbon-heavy transportation and choosing higher carbon activities emits just 81.33 kg of CO² per day. The carbon footprint of an average land-based vacationer is around 51.88kg, less than one-eighth of the average cruisegoer. SEATTLE – Today Friends of the Earth released new data that shows cruise goers emit eight times the amount of carbon dioxide emissions per day than a land-based vacationer. This analysis compares one day of a land-based vacation to one day on a double occupancy cruise ship from Seattle. Cruise ships are incredibly large—among the largest ships in the world—and it takes a lot of fuel to keep them moving. They’re often over three football fields long and can feature pools, ice skating rinks, basketball courts and more.

In addition to doing away with buffets and tips, Virgin Voyages, which launches in 2020, plans to ban single use plastics on board. MSC has already removed most single-use plastics, and many cruise lines have removed most plastic straws. In Genoa, Enzo Tortello, a 75-year-old electronic engineer, lives in front of the city’s port. From his flat he sees and hears nightly parties and daily aqua gym sessions held on docked cruise ships, in addition to breathing in their ceaseless engine exhaust. Some newer ships are being designed to operate on clean alternative fuels including liquefied natural gas (LNG), which has lower sulfur emissions, Salerno explained.

The cruise company plans to work on a massive cruise ship port at Lighthouse Point in the Bahamas. Community groups within the region oppose this port as it will cause harm to their marine ecosystems. Findings from FOE state that this cruise company was forced to pay a fine of $18 million for 21 federal colonies in 1999.

Methane is significantly more damaging to the climate than carbon dioxide. The company added that liquefied natural gas (LNG) “virtually eliminates sulphur oxides by 99%, as well as reducing greenhouse gas emissions by up to 20% when compared to traditional marine fossil fuels, even with methane leakage taken into account”. According to the Cruise Lines International Association (Clia), which comprises 95% of the global cruise industry, including 50 cruise lines and about 70,000 to travel agencies, 93% of the world’s oceangoing cruise liners are built in Europe. The main shipyards for cruise ship construction are in Italy, Germany, France and Finland. Advanced wastewater treatment systems are installed on all new ships and many older ones, as well.
