The World’s Largest Cruise Association Commemorates Earth Day

The Cruise Lines International Association (CLIA) marked today,  the 40th anniversary of the first Earth Day, by taking note of the industry’s continued environmental progress and innovation.

Members of the the world’s largest cruise association, CLIA include  the Royal Caribbean, Disney Cruise Lines, Princess Cruise Lines, Celebrity Cruises, Norwegian and Oceania Holland America, just to name a few.

From the little things like energy efficient LED light bulbs and high-efficiency appliances that reduce energy consumption, to plugging into shore-based power and installing solar panels that sustainably power on-board amenities, the cruise line industry is demonstrating its commitment to sound environmental stewardship.

Did you know?

  • CLIA lines recycle over 79,000 tons of garbage in a given year largely including paper, plastic, aluminum cans and glass.
  • In addition to recycling, waste minimization programs are underway that result in the average cruise passenger producing upwards of 70% less garbage (1.5 lbs/day) than at home (4-5 lbs/day).
  • Reusable laundry bags are being used in guest staterooms, thus removing plastic laundry bags from the waste stream. This simple step can save thousands of bags each voyage.
  • Halogen and incandescent light bulbs have either been replaced on many lines or are being replaced with LED lights, which last 25 times longer, use 80% less energy, and generate 50% less heat.
  • Cruise lines are using ecological, non-toxic, slick hull coatings that save as much as 5% of fuel usage for propulsion.
  • Water re-use systems are at work that recycle engine cooling water for heating passenger cabins, and air conditioning water for use in laundry facilities and for deck washing.
  • Automated air conditioning systems monitor public spaces for passenger occupancy, which automatically shut-off to conserve energy when passengers are not present.
  • Reflective window coatings have been designed especially for cruise ships that deflect sunlight and heat penetration, thus requiring less air conditioning to cool indoor spaces.
  • One line alone invested $400 million toward Research and Development over the last 10 years related to environmental protection.
  • Environmentally-sensitive lubricants are being used for engine systems that biodegrade more than 60% in 28 days compared to conventional marine lubricants, which can take up to a year to biodegrade 50%.
  • Water conserving ice machines on cruise ships require less water by injecting air pockets into ice cubes, which freeze faster and also consume less energy than traditional ice machines.
  • The industry has partnered with Conservation International to serve as an environmental stewardship advisor, helping CLIA member lines consider new initiatives to protect the environment.
