Royal Caribbean Cruises today released a new sustainability report, which it said “documents the Company’s commitment to environmental stewardship and showcases improved efficiencies across its fleet.”

2015 marked the completion of the company’s 10-year Save the Waves goals, which focused on emissions and waste reduction, as well as increasing the number of shore excursions that met an internationally recognized sustainability standard.

“At Royal Caribbean, we are working to put sustainability into the heart of our business,” said Richard D. Fain, Chairman and CEO, Royal Caribbean Cruises Ltd. “We bring 5,000,000 guests to nearly 500 ports around the world every year, and we understand our responsibility to do so in a way that protects the oceans that we sail every day. Our mantra is continuous improvement, and that especially applies to our environmental performance.”

In the report, the company noted the expansion of its Advanced Emissions Purification program, as well as a new set of goals for the year 2020 that were established with input from the company’s global conservation partner, World Wildlife Fund.

There are also sections on emissions and hull configurations.

“We are constantly upgrading the hull designs of our ships to help them perform more efficiently. Royal Caribbean International’s Quantum of the Seas’ hull, one of the most efficient ever built, was designed to reduce drag as the ship moves through the water and to limit non-indigenous marine species’ ability to attach to it and be transferred to other ecosystems as the ship moves from port to port. A new hull design and new coatings were also introduced on Celebrity Solstice-class ships,” said the report.

For the third year, the Royal Caribbean said it developed its sustainability report in accordance with the internationally recognized GRI G4 guidelines. 

Among other highlights: The company achieved a daily water consumption average of 55 gallons/day – nearly half of the U.S. average of 100 gallons/day;  An industry-first software, seven years in the making, is optimizing ship speeds and routes to achieve the best possible fuel efficiency; the company was named to the 2016 World’s Most Ethical Companies list – a distinction granted to only 130 companies in 21 countries; and the company has committed to only sourcing cage-free eggs and gestation-crate-free pork by 2022.
