Cruise Industry Makes Strides in Environmental Technologies

Significant Developments in Environmental Practices

The annual report by the Cruise Lines International Association (CLIA) reveals substantial advancements made by the cruise industry in environmental sustainability. This report outlines measurable progress made by cruise lines in their journey towards achieving lower emissions and adopting cleaner technologies, with a notable focus on hybrid and alternative fuels for their ships.

Fleet Expansion and Composition

The current fleet operated by CLIA encompasses a remarkable 303 vessels, accommodating a combined total of 635,000 lower berths. This represents a healthy increase of 3.6% in overall fleet size compared to the previous year. Most vessels are categorized as small to mid-size, thus offering varied options for cruise-goers while minimizing environmental impacts.

Fleet Size and Categories

In terms of classification, the fleet consists of:

• 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)

Fuel Flexibility and Innovations

CLIA's member lines are leading the charge by diversifying fuel options with modern vessels equipped to utilize renewable biodiesel, green methanol, and liquified natural gas (LNG). This commitment allows for seamless transitions towards zero and near-zero fuels without requiring significant modifications to existing engines.

LNG Implementation

Currently, 19 ships, accounting for 7% of the fleet and 13% of its global capacity, are employing LNG as their primary fuel source. Notably, LNG technology helps in drastically cutting sulfur emissions, nitrogen oxides, and achieving substantial reductions in greenhouse gas emissions.

Technological Advancements in Emission Reductions

With the aim of fulfilling International Maritime Organization (IMO) standards, CLIA members have made strides in implementing advanced emissions reduction technologies. Selective Catalytic Reduction (SCR) systems have been integrated into 71 ships, equating to 25% of the fleet, helping to significantly reduce both particulate and nitrogen oxides emissions.

Onshore Power Supply Systems

Onshore Power Supply (OPS) capability is another innovative technology that enables ships to power themselves while docked, leading to up to a 98% reduction in emissions. As of now, 147 member ships are equipped to connect to shore power, signaling a robust increase compared to previous years.

Wastewater Management Innovations

Environmental sustainability encompasses effective wastewater management too. A significant portion of CLIA’s fleet, consisting of 225 ships, is outfitted with advanced wastewater treatment systems (AWTS) that perform above current treatment facility standards. This proactive approach ensures no untreated sewage is released into ecosystems during normal operations.

Freshwater Sustainability Efforts

In alignment with sustainable practices, most cruise lines produce fresh water on board. Astonishingly, 267 ships are equipped with systems to generate fresh water, some of which can meet their passenger consumption rates sustainably.

About Cruise Lines International Association (CLIA)

Serving as the voice of the global cruise industry, CLIA promotes an environmentally friendly and economically viable cruising experience. As the largest trade association within the cruise sector, CLIA supports sustainable policies, government initiatives, and advanced practices that secure a healthy cruise environment for travelers worldwide. It is projected that the industry will welcome 35.7 million passengers annually, surpassing pre-pandemic figures as consumers express growing interest in eco-conscious travel options.
