According to a study published in Science Direct, the energy consumption and emissions of air pollutants from ships in harbors in Denmark were measured. Food waste is another type of waste generated by cruise ships, and it can also be discharged directly into the ocean. They also generate vast quantities of solid and liquid waste, often dumped into oceans and seas, affecting marine flora and fauna. The entry of chemicals from the cruise ships to the oceans through the grey water or the black water channels is another threat the cruise ships make to the marine ecosystem. The shipping industry that fulfils more than 90 per cent of trade across the world with the help of around 90,000 marine vessels contributes heavily to global pollution and climate change.

Most polluted port cities and countries
Cruise ships are notorious for generating a significant amount of plastic waste, which is a major contributor to ocean pollution. “We have one street in and one street out.” She added that few apparent passengers visited her business, despite its proximity to the dock. “As an environmental justice community, we’re really looking seriously at all the noxious infrastructure and pollutants in the air,” said the councilmember Alexa Avilés.
Ways Cruise Ships are Destroying the Oceans
Avilés said the EDC had expressed support for the legislation “in principle” but wanted to see what that looks like in practice. “They need to get [shore power] in Brooklyn 100% functional at all times because they’ve been dragging their feet on repairing it for a number of years,” she said. A new bill in the city council would crack down on diesel-powered luxury liners, requiring them to connect to the city’s power grid when docked, thus lowering their emissions. The bill would also tackle traffic, noise and pollution related to disembarking passengers. If passed, New York would become the first city on the east coast to pass such an ordinance.
What are the long-term consequences of cruise ship pollution on marine life and ecosystems?
The biggest issues with cruise emissions are the levels of nitrogen oxide, which has been linked to acid rain, higher rates of cancer and other forms of respiratory diseases. As such, cruise operators have been urged to switch to cleaner fuel alternatives with a lower sulfur content by 2020, but few have heeded these calls. Cruise ship emissions are also harmful to marine environments and its inhabitants.
They have a long history of violating environmental regulations and have paid millions of dollars in fines — instead of cleaning up their act. In all European port cities, people are suffering from air pollution because of the booming [cruise] industry. Yet they are overlooking the major role that they play in destroying the very destinations they travel to.

Ana, a 74-year-old retiree, boards the vessel with her grandson and mother-in-law. Originally from Colombia, she has lived in Barcelona for the past three decades and this will be her fourth cruise in three years. While a cruise around the Med or the Antarctic might seem like the height of all-inclusive luxury, you may not feel it’s worth the negative impacts after you read this. In fact, they claim a range of environmental initiatives, but only do so halfheartedly.
Even though cruise ships make up only a small fraction of the global shipping industry, their impact is huge. One fisherman, Mark Severson, recalls in the summer of 2019 sailing through miles of foamy yellow waters in Petersburg, a small island community about 30 miles from the Canadian border and a popular port along the Alaska cruise route. Since then, Severson and his wife, Karen, have been advocating for stronger monitoring of waste dumping on cruise ships. There is fear in some coastal communities that as cruise ship traffic increases, so too will the threat to their waters. Popular port destinations including Victoria and Seattle have seen protests at the return of cruise ships after the lifting of pandemic restrictions.
Globally, cruise ships have a patchy record of maintaining environmental regulations, including within Alaska, but the Pacific waters off the coast of British Columbia are particularly polluted. Disney is working on a massive cruise ship port in the Bahamas at Lighthouse Point. This port is opposed by community groups and will cause harm to coral reefs and migratory patterns of marine wildlife. The Bahamian Island of Eleuthera is known for its clear blue waters, sandy beaches, lemon sharks, and sea turtles.
Noise Pollution
This even factors in the damage from emissions at higher altitude from flying. Anchoring can cause physical damage to coral reefs, while sewage discharge and chemical releases can lead to water pollution, which can harm coral and marine life. To prevent oil spills from cruise ships, it is essential to have proper regulations and management in place. Alaska’s Commercial Passenger Vessel Compliance Program has been cited as a model for other states to follow.

To reduce cruise ships’ environmental footprint, advocates argue that the industry and regulators must do much more, particularly when it comes to the largest ships. Of the 264 ships in CLIA members’ fleets whose owners responded to a survey by the association, 202, or 76.5%, are equipped with advanced wastewater treatment systems (28 did not respond). Gill told Mongabay that CLIA members will achieve 100% coverage as older vessels are retired and new ones come with readymade systems installed. Friends of the Earth needs your help to demand cruise ships stop destroying our oceans. Each year, Friends of the Earth assesses the industry’s business practices with our Cruise Ship Report Card. We were hopeful after the COVID-19 pandemic that companies would evaluate their impacts on the environment, public health, climate, and marine ecosystems — but the majority of the companies continued to receive failing grades.
Sewage includes waste from the toilets and the health facilities on the cruise ship. Such wastewater is rich in bacteria and algae, adversely affecting the oceanic life-forms and the entire marine ecosystem. The ship dumps human waste into our oceans (after passing through sewage treatment plants). And, we have larger cruise ships that can accommodate up to 6680 passengers and 2200 crew members. The scope of the gases emitted from the vehicular emissions on the road and the cruise ship emissions on the sea differs hugely, leading to the pollution of immense proportions in the marine areas. Similarly, recent research also found that the air on the aft areas of cruise ships, particulate matter pollution in detail, is as polluted as the air in significant cities, such as Beijing.
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. There exists a range of new technologies aimed at reducing the waste produced by cruise liners, such as onboard incineration plants, recycling programs, as well as cheaper, less polluting fuel options such as LNG. However, without homogenized standards and strictly enforced international rules, the cruise and shipping industry is likely to continue side-stepping many of the possible solutions. Carbon emissions and dangerous particulates emitted by cruise ships are caused by the quantity and quality of the fuel used by these floating citadels .
Some cruise ship waste streams appear to be well regulated, such as solid wastes (garbage and plastics) and bilge water. 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. The industry is under scrutiny over air pollution and contribution to greenhouse gases, with some European cities banning vessels from central ports. Cruise operators say ships can reduce emissions by switching off engines and plugging into low-carbon electricity when moored. But an investigation by openDemocracy has found that cruise ships regularly fail to use onshore power at Southampton, Britain’s largest cruise port.
The program has implemented strict regulations for cruise ships to prevent oil spills and protect the environment [4]. According to a study published in the Journal of Marine Pollution Bulletin, cruise ships have the potential to contribute to accidental oil spills due to their large size and the amount of fuel they carry [1]. Cruise ships also release sulfur dioxide, a harmful gas that can cause respiratory problems and acid rain.
