Cruise Lines Clamp Down on Sunscreens: The Surprising Reason Behind the Bans - The Surprising Reason Behind the Bans


In 2023, the International Maritime Organization (IMO) introduced a new regulation banning the use of oxybenzone and octinoxate-based sunscreens on cruise ships to protect coral reefs. Major cruise lines, including Carnival, Royal Caribbean, and Norwegian, have already implemented this ban, prohibiting passengers from bringing these types of sunscreens onboard. The ban extends beyond just cruise ships, with some Caribbean islands, like the Bahamas and the US Virgin Islands, also prohibiting the sale of sunscreens containing these chemicals. According to a recent study, oxybenzone and octinoxate can cause coral bleaching and disrupt the development of coral larvae, leading to the degradation of coral reef ecosystems. Cruise lines are now providing alternative, reef-safe sunscreen options for purchase on board, encouraging passengers to use these more environmentally-friendly products. The sunscreen ban has led to an increase in demand for mineral-based and natural sunscreens, as these formulas are typically considered safer for marine environments. Some cruise lines are also exploring the use of biodegradable and eco-friendly cleaning products on board to further reduce their environmental impact. Passengers who attempt to bring banned sunscreens onto cruise ships may face fines or have their products confiscated, as cruise lines strictly enforce the new regulations. The sunscreen ban is part of a broader effort by the cruise industry to improve its environmental sustainability and reduce its impact on marine ecosystems. Cruise lines are also working with local governments and conservation groups to support coral reef restoration projects in the destinations they visit.
