Cruise Ship Pollution Exceeds WHO Safety Levels, Poses Health Risks

Recent air quality readings at Cobh, Ireland, have revealed alarming pollution levels attributed to cruise ships, which were found to reach 250 times the World Health Organization's (WHO) recommended safe levels. This finding highlights ongoing concerns regarding the environmental and health impacts of maritime travel, particularly in popular tourist destinations.

According to a report by EU Reporter, ultra-fine particles from cruise ships were measured at 250,000 particles per cubic centimeter in residential areas near the port. The WHO considers 1,000 particles per cubic centimeter to be a safe threshold for air quality. This significant deviation raises serious alarms about public health, as air pollution has been linked to various health issues, including cancer, cardiovascular disease, respiratory diseases, and other serious conditions, according to the National Institute of Environmental Health Sciences.

The pollutants primarily emanate from cruise ships operating on less environmentally friendly fuel sources, contributing to black carbon emissions, also known as soot. Sian Prior, lead advisor to the Clean Arctic Alliance, noted, “Black carbon particles are lethal to humans when inhaled, but they also drive climate change.” The report further explained that when black carbon settles in the Arctic, it exacerbates snow and ice melt, impacting global climate patterns.

Historically, the cruise ship industry's environmental impact has been scrutinized, prompting cities like Amsterdam to impose restrictions on cruise ship operations. Similarly, ports in Florida, Maine, Alaska, and California are contemplating similar bans due to the rising pollution levels and the overwhelming tourist influx.

In response to the mounting evidence of pollution, advocates are urging the implementation of shore power facilities in ports like Cobh. Kåre Press-Kristensen, senior advisor on air quality and climate at Green Global Future, stated, “This will allow ships to connect to the electricity grid instead of idling and polluting all day.” Such measures are essential for reducing emissions and improving air quality in port cities.

Ireland has also expressed support for the establishment of a Northeast Atlantic Emission Control Area, approved by the International Maritime Organization (IMO) in April 2023. This initiative aims to mandate the use of cleaner fuels in the region, including all of Ireland’s waters, by 2027 if adopted later this year. Prior emphasized the importance of accompanying these measures with onshore power facilities to further mitigate emissions from ships in port.

As global awareness of environmental issues escalates, the cruise ship industry faces increasing pressure to adopt sustainable practices. The introduction of stricter regulations and cleaner technologies may represent a pivotal step towards improving air quality and protecting public health in coastal communities worldwide. The implications of these developments are profound, as they not only impact local residents but also signify a broader trend towards environmental accountability in the tourism sector.
