Carnival Cuts Food Waste 44%, Exceeds 2025 Sustainability Goal

Carnival Corporation has reached a key sustainability milestone by cutting unit food waste by 44 percent in 2024 compared to 2019 levels, surpassing its 2025 target of 40 percent reduction one year early. The cruise giant remains on track to meet its 50 percent food waste reduction goal by 2030.

The achievement is part of Carnival’s “Less Left Over” initiative, which focuses on reducing food waste through improved provisioning, preparation, and meal service practices. Since 2019, the program has helped Carnival save over $250 million. The company employs data analytics to optimize ingredient purchasing, trains crew members to plate meals more efficiently, serves smaller portions, and donates surplus food to local food banks.

Carnival also finds creative ways to repurpose food waste. Used coffee grounds are transformed into vegan soaps, while used cooking oil is converted into biofuel for its Alaska land tours. For waste that cannot be repurposed, the company has installed 630 biodigesters across its fleet. These devices use bacteria to break down uneaten food, dramatically reducing its volume. Additionally, more than 90 dehydrators and dryers help remove water from harder-to-process waste like fruit rinds, cutting waste volume by up to 90 percent. The remaining material can be processed into mulch or compost.

“Our Less Left Over strategy turns everyday actions into lasting impact,” said Josh Weinstein, CEO of Carnival Corporation. “It’s great for the planet and our bottom line, and reflects the dedication of our 160,000 team members worldwide.”
