Debate Arises in Cruise Ship Industry over United Nations’ New Emissions Regulations

The United Nations’ new emissions regulations have caused a debate within the cruise ship industry. Cruise lines argue that the Carbon Intensity Indicator (CII), introduced by the International Maritime Organization (IMO), does not take into account the unique nature of cruise ships. Unlike cargo ships and ferries, cruise ships are not simply means of transportation but are floating holiday destinations. Their electricity consumption is largely used for hotel-like services, such as entertainment venues and gourmet meals. Additionally, cruise ships spend a significant amount of time in port, allowing tourists to explore the area. However, the current CII rule penalizes this idle time as it does not include travel distance. Cruise Lines International Association (CLIA) believes that this creates an unfair incentive for ships to sail longer distances and shorten their port time to score better on CII, potentially resulting in higher overall emissions.

Carnival Corp, the world’s largest owner and operator of cruise lines, proposes a different approach. They suggest assessing the carbon intensity of entire fleets, rather than individual ships. They also advocate for the use of onshore power supply (OPS), or “shore power,” connected to renewable energy sources such as offshore wind energy. This would allow cruise ships to use local power grids in port and significantly reduce emissions.

However, implementing these changes faces challenges. Environmental groups may argue that it creates loopholes in existing regulations, and securing funding for fully renewable shore power is a hurdle. Other obstacles include regulatory limitations and the standardization of a solution across various vessel types.

In conclusion, cruise lines argue that the current emissions regulations do not account for the unique nature of cruise ships, and propose alternative approaches such as fleet-wide assessment and the use of renewable shore power. However, implementing these changes poses challenges that need to be addressed.
