Carnival Corporation is seeking to enhance its green credentials through a tie-in with ocean explorer and environmental advocate Jean-Michel Cousteau.

Cousteau runs Ocean Futures Society, a non-profit marine conservation and education organisation.

He will provide “valuable external expertise” to the world’s largest cruise group on environmental initiatives.

The corporation and its nine cruise line brands already plans to reduce or eliminate purchase of plastic straws, cups, lids and bags, among other single-use items.

The lines are also working to “potentially eliminate” providing individual servings of select packaged food items and other single-use plastics or decorative items used in food and drink service as well as in cabins.

The company recently announced that it will “significantly reduce” the purchase and use of non-essential single-use plastics by the end of 2021 as part of an ongoing ‘Operation Oceans Alive’ initiative.

Cousteau said: “We are all connected to the ocean in some way no matter where we live, and it is clear that the health and vitality of the world’s oceans depend on our collective global commitment to preserving the environment that we all share.

“As we look to the future, we have a responsibility and opportunity to demonstrate the importance of the world’s oceans, while supporting and protecting them with sound environmental policies.

“We look forward to working with Carnival Corporation to further enhance its environmental initiatives, and we commend the company’s long-term commitment to environmental stewardship and excellence.”

A Carnival Corporation spokesman added: “With over 120,000 dedicated employees, most of whom live and work at sea, our commitment to protecting and sustaining the oceans on which we sail and the communities we visit around the world is a top priority for our company.

“We enthusiastically welcome the Ocean Futures Society and Jean-Michel’s passion and insights to help us strengthen our efforts, along with the support of our employees and guests.”
