Key Progress in Environmental Practices
The latest report from the Cruise Lines International Association (CLIA) highlights significant strides made by the cruise industry in terms of environmental sustainability. This report details the measurable advancements that cruise lines have achieved as they work towards reducing emissions and embracing cleaner technologies, particularly through the use of hybrid and alternative fuels for their ships.
Expansion and Composition of the Fleet
Currently, CLIA operates an impressive fleet of 303 vessels, which collectively offer 635,000 lower berths. This marks a healthy growth of 3.6% in the overall fleet size compared to last year. The majority of these vessels fall into the small to mid-size category, providing diverse options for travelers while also minimizing their environmental footprint.
Categories of Fleet Size
The fleet can be categorized as follows:
- 35% small ships (fewer than 1,000 lower berths)
- 38% mid-size ships (1,000 to less than 3,000 lower berths)
- 26% large ships (more than 3,000 lower berths)
Innovations and Fuel Flexibility
CLIA's member lines are at the forefront of diversifying fuel options, with modern vessels designed to use renewable biodiesel, green methanol, and liquefied natural gas (LNG). This commitment facilitates a smooth transition towards zero and near-zero fuels without necessitating major changes to existing engines.
Implementation of LNG
At present, 19 ships—representing 7% of the fleet and 13% of its global capacity—are utilizing LNG as their main fuel source. This technology is particularly effective in significantly reducing sulfur emissions, nitrogen oxides, and achieving notable decreases in greenhouse gas emissions.
Technological Advances in Emission Reduction
To meet the standards set by the International Maritime Organization (IMO), CLIA members are making progress in adopting advanced technologies for emissions reduction. Selective Catalytic Reduction (SCR) systems have been installed on 71 ships, which accounts for 25% of the fleet, contributing to a substantial reduction in both particulate matter and nitrogen oxides emissions.
Onshore Power Supply Systems
Another innovative technology is the Onshore Power Supply (OPS) capability, which allows ships to draw power while docked, resulting in up to a 98% reduction in emissions. Currently, 147 member ships are equipped to connect to shore power, indicating a significant increase from previous years.
Innovations in Wastewater Management
Effective wastewater management is also a crucial aspect of environmental sustainability. A significant segment of CLIA’s fleet, comprising 225 ships, is equipped with advanced wastewater treatment systems (AWTS) that exceed current treatment facility standards. This proactive measure ensures that no untreated sewage is discharged into ecosystems during normal operations.
Efforts in Freshwater Sustainability
In line with sustainable practices, many cruise lines are capable of producing fresh water on board. Remarkably, 267 ships have systems in place to generate fresh water, with some able to meet their passengers' consumption needs sustainably.
About the Cruise Lines International Association (CLIA)
As the leading voice of the global cruise industry, CLIA advocates for an environmentally responsible and economically sustainable cruising experience. Being the largest trade association in the cruise sector, CLIA supports sustainable policies, governmental initiatives, and innovative practices that foster a healthy cruising environment for travelers worldwide. The industry is projected to welcome 35.7 million passengers annually, surpassing pre-pandemic levels as travelers increasingly seek eco-friendly travel options.
