Carnival Corporation: A Deep Commitment to Sustainability 

Sustainability is a top priority for Carnival Corporation, the world’s largest leisure company featuring nine of the world’s most popular and iconic cruise line brands, which include Carnival Cruise Line, Cunard, Holland America Line, Princess Cruises, Seabourn, AIDA Cruises, Costa Cruises, P&O Cruises Australia and P&O Cruises UK. With more than 100 ships annually sailing millions of guests to over 700 global ports, the company and its brands have a deep commitment to operating responsibly, as its very existence is tied to protecting the oceans, seas and communities its ships visit. 

 Through the efforts of its 120,000 employees, a passionate workforce representing over 150 countries, Carnival Corporation has experienced remarkable year-over-year growth and prides itself on consistently exceeding guest expectations by delivering extraordinary vacations at an exceptional value. At the same time, the corporation sets and consistently achieves aggressive sustainability goals to reduce its carbon footprint, improve air emissions, reduce waste generation, improve water use efficiency, and support guests, crew members and communities. As part of its goal-setting, the company uses the United Nations’ 17 Sustainable Development Goals as a recognized framework. 

Innovations for A Healthy Environment  

Working with the U.S. Environmental Protection Agency and other authorities, the company pioneered adapting exhaust gas cleaning systems (ECGS) for use in the marine environment. 

ECGS works by spraying alkaline wash water into the exhaust stream, effectively washing out sulfur oxides and particulate matter for clean air emissions while having no negative impact on oceans and seas. 

In another innovation, Carnival Corporation is the first to build cruise ships using liquefied natural gas (LNG), the world’s cleanest burning fossil fuel. AIDAnova from its AIDA Cruises brand is launching (December 2018) the world’s first fully LNG-powered cruise ship, capable of running on LNG in port and at sea. Carnival Corporation has 10 more LNG ships on order. Other notable progress includes “cold ironing” – cruise ships in port plugging into the land-based electrical grid; and further enhancing water treatment with Advanced Waste Water Purification Systems. 

Partnering to Support Sustainability 


One of many examples of its corporate and brand partnerships with sustainability groups, Carnival Corporation partners with The Nature Conservancy on the Mapping Ocean Wealth initiative to measure and quantify the value of the world’s ocean habitats, including coral reefs and salt marshes. The partnership also supports TNC’s efforts to protect and sustainably manage the Caribbean region’s critical marine resources. 

Carnival Corporation recognizes the inextricable link between its business and vitality and sustainability of communities it visits and calls home. It continually promotes sustainable tourism by contributing to communities in a positive social, environmental and economic manner, working with local governments, trade and tourism associations, and other stakeholders. 

Travel is a powerful way for people from different cultures to discover what they have in common and to learn, respect and appreciate their differences. For Carnival Corporation and its nine cruise line brands, its voyages are another way to bring sustainability to the world.
