Carnival has become the first cruise line to join Getting to Zero Coalition as part of its efforts to develop low-carbon shipping.
The move comes as, faced with pressure from environmentalists and the public, the Miami-based cruise giant has been keen to improve its green credentials via decarbonisation initiatives.
Carnival’s senior vice-president of maritime affairs Tom Strang said: “We look forward to working with fellow coalition partners in the maritime, energy and other related industries, as well as academics, think tanks and policymakers."
