Some ships have not been adapted to use cleaner onshore power, but the UK Chamber of Shipping says one factor is cost, because onshore power is more expensive than marine fuel. Cruise firms can also pay for their ships to be retrofitted with new technology so they can use cleaner onshore power. 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”.

Boat and shipyard staff also have to live with difficult working environments and the risk of injury. However, while welcome, the move is not enough, Bissonnette says, noting that the measures are voluntary and do not apply to scrubbers. [2] Methane’s (CH4) global warming potential (GWP) is 82.5 times higher than CO2 over a period of 20 years and 29.8 times higher over a 100-year period.

Noise pollution can cause hearing loss, stress, and behavioral changes in marine animals, which can ultimately lead to decreased reproduction rates and population decline.

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. “The passengers that love the Alaska cruise do not even realise that the ships are polluting our pristine parts of the world,” he says. The fishing communities of south-east Alaska also complain of dumped waste in their waters bordering Canada, fearing that critical fish species are being exposed to harmful substances. Additionally, pollution can contribute to the spread of invasive species, which can have long-term impacts on local ecosystems. Cruise ships generate a significant amount of sewage waste, which is often disposed of in the ocean.
What is the impact of cruise ship emissions on air and water quality?
All market projections show that the industry will continue to grow as operators continue to build new state-of-the-art ships with the latest in leisure opportunities. However, as nations strive to reduce their CO2 emissions and companies come under pressure to decrease their carbon footprint, the maritime industry is finding itself under growing scrutiny . Whilst commercial shipping has always been at the center of environmental concerns, the issues surrounding cruise ships are being increasingly called out in the port cities in which they dock.
Pollution can harm marine mammals, disrupt food chains, and damage coral reefs and other sensitive habitats. Additionally, regulations and policies can be put in place to limit the environmental impacts of cruise ships. Additionally, cruise ships can damage marine ecosystems through activities such as anchoring, dredging, and discharging ballast water. Noise pollution from cruise ships can have a significant impact on marine life, particularly on species that rely on sound for communication, navigation, and hunting.
This resulted in an increase of 9% in SOx emissions, 18% in NOx emissions and 25% in PM2.5 emissions – three toxic air pollutants. A report released earlier this year by the Brussels-based NGO Transport & Environment detailed that Europe’s fleet of 218 cruise ships emitted as much sulfur oxide in 2022 as a billion cars. As it stands, BC emissions are not currently directly regulated at an international level. The Arctic Council and the International Maritime Organization are, however, looking further into the impacts of black carbon in the Arctic.
Cruise ships generate a significant amount of waste, including air emissions, ballast water, wastewater, hazardous waste, and solid waste. One of the most significant ways cruise ships cause ocean pollution is through the direct discharge of waste into the ocean. It is estimated that cruise ships use, on average, 150 tons of heavy fuel oil every day. With the bilge oil mixing with oceanic water, the use of this oil causes marine pollution. Faulty engine systems and improper repair work are two areas where oil could leak and mix with the oceanic water. While cruising is one of the fastest growing tourism sectors, with 31.5m passengers forecast for 2023, there are concerns about its environmental impact.

This protected area is subject to the highest amount of pollution from cruise ship dumping, according to WWF’s report. Across Canada’s 151,019 mile (243,042km) coastline, ships generate 147bn litres of harmful waste each year, equivalent to 59,000 Olympic-sized swimming pools, according to a March 2022 report by WWF-Canada. Based on data from more than 5,000 vessels, the report found cruise ships were the largest polluters, despite making up only 2% of the marine traffic analysed. The hotel facility must be heated, cooled, and illuminated for guests needs. The energy comes from the ship’s engines — which are forced to produce the same energy that’s required to power a small city.
Open-loop systems send the wash water directly into the sea, and it can be hot, highly acidic and contain a host of pollutants, including particulate matter, polycyclic aromatic hydrocarbons, and heavy metals. Closed-loop systems recirculate and continuously treat freshwater, collecting the resulting waste on board for later disposal on shore. Cruise ships are a catastrophe for the environment — and that’s not an overstatement. They dump toxic waste into our waters, fill the planet with carbon dioxide, and kill marine wildlife. Cruise ships’ environmental impact is never ending, and they continue to get bigger.
A ship’s back house also often includes a small hospital, prison and morgue. Outside, the summer sun is scorching but inside, corridors are pumped with air cooled to 20C. Brimming with luxury and colour, the cruise ship is like an overcrowded five-star hotel.
Thus, even the most regular activity onboard the cruise ship, such as cleaning utensils and doing the laundry, causes cruise ship pollution. Today, Oceana launches a week-long media tour in three cities – Washington, New York and Boston – to continue raising awareness about cruise ship pollution. The campaign to protect our oceans and stop cruise ship pollution exposes how cruise ships threaten the health of the world’s oceans, including some of the most pristine and delicate parts of our ocean where cruise ships travel. About 10% of scrubber washwater discharged from ships off British Columbia occurred within critical habitats of orcas, according to an analysis by the International Council on Clean Transportation. Of particular alarm, says Kuehnemund, is the threat to wildlife in Scott Islands marine national park, a cluster of five islands off the north-western tip of Vancouver Island.
Ships are still refusing to fully convert to truly green initiatives like shorepower. Until the cruise industry cleans up its act, you can unfortunately count on them to continue having a negative impact on the environment. Some large cruise shipping lines have violated regulations by illegally bypassing the onboard oily water separator and discharging untreated oily wastewater. These violations by means of a so-called "magic pipe" have been prosecuted and resulted in large fines.
Though Meraviglia is shore power-equipped, its connector is too far out to reach the stationary plug-in at the Brooklyn terminal – arguably, due to its size. “As the brand with more vessels in operations in Europe than our competitors, we have long recognised the importance of reducing emissions in European ports and wherever we operate around the globe,” a spokesperson said. How beneficial these visitors are to a city’s tourism industry is hotly debated. Cruise ship companies say that during a seven-day trip, passengers spend €760 (£662) on average at destinations.
Though representing a small fraction of the industry, cruise liners, as much as the entertainment they provide, are also a source of significant pollution in the oceanic and marine areas like commercial vessels. A luxury cruise ship releases ten times more carbon emissions than all of Europe’s cars. In April, on the eve of the new cruise ship season, the federal government department Transport Canada announced new measures to limit discharges of greywater and sewage from cruise ships operating in Canadian waters.
