Carnival Upgrades Global Fleet with Green Tech

Carnival Corporation announced today that it will be rolling out comprehensive technology upgrades called Service Power Packages across its global fleet to further improve energy savings and reduce fuel consumption.

The upgrades include ongoing installations through 2023 on ships from all nine of the company’s brands: Carnival Cruise Line, Princess Cruises, Holland America Line, Seabourn, P&O Cruises, P&O Cruises Australia, Cunard, Costa Cruises, and AIDA Cruises.

The upgrade program delivers an average of five to 10 percent fuel savings per ship, and is expected to reduce fleetwide greenhouse gas emissions by over 500,000 metric tons each year. Upon completion, the program is also expected to generate over $150 million in annual fuel cost savings.

Developed over the past six years, the Service Power Packages will deliver significant efficiency upgrades, including cabin and public area air conditioning upgrades and major enhancements to cooling, lighting, and automation systems.

Adjusting for variations in ship design, size, and equipment, the company customizes the package for each ship. It includes the following elements:

  • Comprehensive upgrades to each ship’s hotel HVAC systems, accounting for 25 percent of a ship’s energy consumption, to improve hotel ventilation efficiency using sophisticated variable speed drives and on-demand systems throughout public areas, cabins, and galleys. Indoor air quality is continuously monitored and maintained to the highest standards at sea, using an industry-leading air filtration and ultraviolet-C treatment throughout the ship.
  • Technical systems upgrades on each ship using variable speed drives and on-demand automated control systems for engine room ventilation, main air conditioning chillers, and cooling pumps, which together lower the energy needed to deliver cooling around the ship.
  • State-of-the-art LED lighting systems installed throughout each ship to reduce both power consumption and heat load generation, creating a dual benefit from lower air conditioning demand.
  • Remote monitoring and maintenance improvements that maximize benefits from the upgrade packages, including improved instrumentation and automated management systems, with nonstop ship-to-shore connectivity. Expanded remote monitoring and analysis of each ship’s energy performance and technical status ensure peak efficiency and minimal down times.

These enhancements across Carnival Corporation’s global fleet are part of the company’s ongoing energy efficiency investment program and efforts to reduce fuel consumption, including over $350 million invested in energy efficiency improvements since 2016, along with its fleet optimization strategy and design of more efficient itineraries.

Together, these efforts are expected to drive a 10 percent reduction in fuel consumption per available lower berth day in the company’s first full year of guest cruise operations compared to 2019, along with a nine percent reduction in carbon emissions per lower berth distance traveled.

As part of its longer-term sustainability plan and vision, Carnival Corporation has committed to significant investments to achieve its 2030 sustainability goals and 2050 aspirations, which incorporate six focus areas. These include climate action, circular economy, sustainable tourism, good health and well-being, diversity, equity and inclusion, and biodiversity and conservation.

Among these priorities, Carnival Corp. has committed to reducing carbon emissions by 20 percent from its 2019 baseline by 2030.
