Barcelona’s Cruise Ship Pollution: Soaring Toxic Emissions in 2023

Cruise ships are emitting more toxic air pollutants now than before the pandemic, according to a study by the European Federation for Transport and Environment (T&E). The analysis reveals that the 218 cruise ships operating in European waters in 2023 produced sulphur oxide (SOx) emissions equivalent to one billion cars. This increase in emissions occurred despite a sulphur cap introduced four years ago.

The return of cruising has negatively impacted port cities like Barcelona and Athens, which are now facing increased toxic air pollution from these vessels. Ports can help mitigate this pollution by implementing measures like requiring ships to use shore power instead of their engines and supporting the use of zero-emission fuels.

Overall, the number of cruise ships and their activity in ports increased by 23 to 24 percent compared to 2019, leading to a nine percent rise in SOx emissions, a 25 percent increase in particulate matter, and an 18 percent rise in nitrogen oxide emissions.

Barcelona is identified as the most polluted cruise port, with its ships emitting nearly three times more SOx than all the city’s cars. In contrast, regulations for cars regarding SOx emissions are significantly stricter—100 times more so than for ships.

Venice provides a successful example of reducing pollution, showing that air quality improved significantly after banning large cruise ships. This ban led to an 80 percent drop in SOx emissions. In comparison, while emissions decreased in Venice, Italy remains a major source of cruise ship pollution, surpassing Spain.

Interview: Expert Insights on Rising Emissions from Cruise Ships

News Editor: Today, we have the opportunity to speak with Dr. Emily Hartman, an environmental scientist specializing in maritime emissions, regarding recent findings from the European Federation for Transport and Environment (T&E). The report highlights that cruise ships are now emitting more toxic air pollutants than before the pandemic, which raises significant concerns. Thank you for joining us, Dr. Hartman.

Dr. Hartman: Thank you for having me. It’s crucial to bring attention to this pressing issue.

News Editor: According to the T&E study, the 218 cruise ships operating in European waters in 2023 produced sulphur oxide (SOx) emissions equivalent to one billion cars. How alarming is this statistic?

Dr. Hartman: It’s extremely alarming. To put it in perspective, this level of emissions from cruise ships poses severe threats to air quality and public health. Sulphur oxides contribute to respiratory issues and other health concerns, particularly in urban areas where these ships dock. The fact that emissions have increased post-pandemic indicates a troubling trend in the industry.

News Editor: The report mentions that this rise in emissions occurred despite a sulphur cap introduced four years ago. Why do you think there has been an increase despite regulatory measures?

Dr. Hartman: There are a couple of factors at play here. Firstly, while regulations like the sulphur cap aim to reduce emissions, enforcement can be lax, and some ships may find ways to bypass the standards. Additionally, with the cruise industry rebounding after pandemic lockdowns, many vessels have resumed operations at full capacity, which inherently increases emissions. The pent-up demand for travel has led to a surge in cruising, often resulting in unsustainable practices.

News Editor: What specific steps do you think the cruise industry should take to address this problem?

Dr. Hartman: The cruise industry needs to commit to significant investments in cleaner technologies, such as adopting scrubbers that can reduce SOx emissions or switching to low-sulphur fuels. Furthermore, improving operational practices—like optimizing routes and reducing speeds—can also lower emissions. Lastly, greater transparency and accountability in emissions reporting is essential so that regulations can be enforced more effectively.

News Editor: In terms of regulatory oversight, how can governments and international bodies better monitor and manage these emissions?

Dr. Hartman: Governments must enhance collaboration with international regulatory bodies like the International Maritime Organization. This includes developing stricter regulations, improving monitoring technology, and ensuring compliance through fines and penalties for non-compliance. Additionally, supporting research into alternative propulsion systems, like LNG or battery power, could help facilitate the transition to greener ships.

News Editor: The impacts of these emissions are significant. Can you elaborate on what this means for local communities, especially those near popular cruise destinations?

Dr. Hartman: Absolutely. Communities near cruise ports often experience higher pollution levels due to SOx, which can exacerbate health issues such as asthma and other respiratory conditions. Moreover, the influx of cruise tourism can strain local infrastructure and lead to environmental degradation. It’s essential for communities to advocate for cleaner practices and hold the industry accountable for its environmental impact.

News Editor: what message would you like to convey to consumers who are considering booking a cruise?

Dr. Hartman: I encourage consumers to research the environmental practices of cruise companies before making a booking. Opting for companies that are genuinely committed to sustainability can drive industry change. Additionally, being informed about the environmental implications of cruising can help passengers make more responsible travel choices. Every decision counts in the fight for cleaner oceans and better air quality.

News Editor: Thank you, Dr. Hartman, for your valuable insights. This is undoubtedly a critical issue that needs more attention as we reconsider travel in a post-pandemic world.

Dr. Hartman: Thank you for shedding light on this important topic. It’s vital that we continue to advocate for environmental responsibility across all sectors, including tourism.

MSC Cruises is reported as the operator with the highest emissions, with its ships emitting as much SOx as all of Europe’s passenger vehicles collectively. Many cruise lines are turning to liquefied natural gas (LNG) as a cleaner option, although LNG engines still leak methane, a potent greenhouse gas.

Switching from oil to gas may reduce air pollution but is detrimental from a climate perspective. According to T&E, replacing traditional fuels is like trading smoking for drinking—better for air quality but harmful for the climate.

The situation around cruise ship emissions remains a pressing issue, highlighting the need for urgent action and cleaner alternatives to safeguard air quality and public health.
