Carnival Corporation, the world’s largest leisure travel company, is building new ships powered by LNG, and cruise operators are also conducting trials with biofuels. New LNG engines reduce emissions of sulphur oxides but campaigners say the engines and the fuel production process leak methane, an extremely potent greenhouse gas. While cruising is one of the fastest growing tourism sectors, with 31.5m passengers forecast for 2023, there are concerns about its environmental impact. A study published in the journal Marine Pollution Bulletin in December 2021 found a large cruise ship could have a carbon footprint greater than 12,000 cars.
Noise Pollution
The long-term consequences of cruise ship pollution on marine life and ecosystems can be significant. Pollution can harm marine mammals, disrupt food chains, and damage coral reefs and other sensitive habitats. The study found that while cruise ship emissions were not the sole source of air pollution in the port, they did contribute to the overall levels of pollution. To reduce the impact of direct waste discharge, some regulations have been put in place. However, there is still a need for more stringent regulations and enforcement to ensure that cruise ships do not cause further harm to the ocean and its inhabitants. If anything should change after Covid-19 and not go back to normal, it’s cruise ships and the voracious industry that operates them.

Norwegian Cruise Lines controls nine percent of the North American market and, along with Carnival Corp. and Royal Caribbean Cruises Ltd., is considered one of the 'big three' corporations which dominate the U.S. cruise ship market. Princess Cruises was founded in 1965 and is a subsidiary of Carnival Corp., the world's largest cruise operator. Seabourn Cruise Line was founded in 1986 and is a subsidiary of Carnival Corp., the world's largest cruise operator.
Some ships use the oceans as their trash can
There are several ways which cruise ships can become more sustainable and eco-friendly, such as by seeking to build more sustainable liners and seeking to implement energy efficiency wherever possible. According to Stand.Earth’s Barford, the vast majority — around 90% — of wastewater pollution in Canada’s waters is scrubber water. Canada’s newly mandatory regulations don’t touch scrubbers, she said, meaning they don’t address a large portion of pollution. In Folbert’s view, simply treating waste isn’t sufficient and companies must take a “broad perspective” on the variety and sources of pollutants to ensure adequate wastewater management. This means considering the fate of substances like microplastics, caffeine and pharmaceuticals that can escape treatment. For some time, campaigners have highlighted the dumping of sewage and wastewater as the face of an unsustainable cruise industry.
This could prove possible with a cruise ship designed to cling closer to the water, implementing solar powered retractable sails, and opting for battery-powered sailing as opposed to the use of fossil fuels. If all goes according to plan, this first ever sustainable cruise ship could be ready to set sail by 2030. In fact, taking a cruise is worse than flying – with the average cruise ship trip resulting in anywhere from 700 to 1,000 pounds of carbon dioxide emissions per day. The largest cruise companies are located in the the United States, as evidently – a cruise ship is a popular choice amongst Americans as opposed to Europeans who are more likely to take a train to their holiday destination. You can also look up the performance of specific ships – because they’re all different, even when they’re owned by the same company.
‘Biggest, baddest’ – but is it the cleanest? World’s largest cruise ship sets sail
The only other cruise line to get above a D grade was Silversea Cruises, which was awarded a C, scoring highly in water quality compliance and transparency. “Carnival Corporation - the corporate parent for 10 major cruise lines including Princess, Holland America and Costa. Carnival Corp. is currently on federal criminal probation in the United States for environmental crimes,” says Keever. The study also found that a large cruiseliner can have a bigger carbon footprint than 12,000 cars, while an overnight stay onboard uses 12 times more energy than a stay in a hotel. Hurtigruten is aiming for carbon-neutral operations by 2040, and to cut all scope three emissions—those from the company’s supply chain—by 2050.

They have a long history of violating environmental regulations and have paid millions of dollars in fines — instead of cleaning up their act. Friends of the Earth works diligently to collect vital information about cruises to help the public understand their impacts. In our Cruise Ship Report Card we assess the largest cruise lines and their ships. Unfortunately, everything that cruise ships come in contact with are likely to be harmed along their journey. The air, water, fragile habitats, coastal communities, and wildlife are all affected. But most governments have refused to take actions to actually regulate the cruise industry and buried their heads in the sand to ignore the ongoing damage to the environment and communities.
It can also get into clouds and help evaporate them more quickly, which causes further warming because clouds help reflect sunlight. 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.
To tackle the issue, cruise ship owners are installing advanced wastewater treatment systems. The trade group represents the owners of 292 cruise ships, roughly 95% of the global fleet, according to Gill. CLIA member companies served roughly 30 million passengers per year pre-COVID-19. To what degree did cruise ships violated water pollution standards designed to better protect the Alaskan coast. In determining the Water Quality Compliance grade for cruise ships, we used notices of violation issued for individual cruise ships to each cruise line by the Alaska Department of Environmental Conservation from 2010 to 2019.
COVID-19 lockdowns are no longer preventing vacationers from traveling the globe this summer, which has caused a jump in travel among Americans and elsewhere. Carnival Cruise Line and other top cruise ship companies have been breaking records for ticket sales this year. But a water-bound vacation isn’t just a concern for infectious disease—these ships are having a massive effect on the climate.
An analysis published in June by T&E found that despite the introduction of a new cap of sulphur in marine fuels in 2020, 218 cruise ships operating in Europe in 2022 emitted more sulphur oxides than a billion cars. In France, 10% of air pollution in the port city of Marseilles can be directly contributed to the shipping industry. It is estimated that over 50,000 Europeans die prematurely every year as a result of shipping-based pollution.
A cruise ship refers to a large ship, with the modern cruise ship weighing in at around 200,000 gigatonnes – which is made for leisure sailing and recreational activities. Following the pandemic, it seems that everyone is making up for lost time – booking flights for the trips they’ve been dreaming about forever and booking novelty cruise ship packages for their families to enjoy. To determine the Transparency grade for each cruise line we graded each line based on whether it responded with specificity to our 2022 requests for information regarding their environmental practices. 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. It’s kind of amazing – there are so many opportunities for cruise companies to do the right thing, but just keep choosing to be terrible polluters, instead.
Cruise ships are often the perfect “middle ground” choice for any vacation – as cruise ships can be suitable for solo travelers, romantic getaways, and family-friendly entertainment all aboard the same ship. In a study published in the Journal of Environmental Science and Pollution Research, it was found that oil spills can cause both short-term and long-term damage to marine ecosystems [3]. The study found that sulfur dioxide emissions from cruise liners were higher than other types of ships, and the emissions were highest when the ships were docked.
