👉 Cruise ship emissions release a cocktail of pollutants into the air, contributing to air pollution and health concerns. These ships emit sulfur oxides (SOx), nitrogen oxides (NOx), particulate matter (PM), and carbon dioxide (CO2), which can cause respiratory issues, exacerbate asthma, and contribute to climate change. The concentration of these emissions is particularly high in port cities due to the large number of passengers and the relative lack of stringent air quality regulations compared to land-based sources. While modern cruise ships have implemented some measures to reduce emissions, such as using cleaner fuels and exhaust treatment systems, the sheer size and frequency of these vessels mean that their environmental impact remains a significant issue.
