Carnival Corporation’s focus on reducing fuel consumption is generating returns, with CEO Josh Weinstein disclosing on the company’s first quarter 2026 earnings call that efficiency gains are saving the company approximately $650 million this year alone when compared with 2019.

“Whatever the price is, if we use less, we do better,” he said, adding the company was hyper-focused on consumption savings.

He added that per-unit consumption reductions achieved since 2023 are responsible for $250 million of that total  savings he described as the direct result of that.

Weinstein outlined a range of measures contributing to the gains: tighter management of itineraries and arrival timing, HVAC optimization and two rounds of the company’s Service Power Package program, a corporate-led program to give brands a menu of options to install on ships.

Carnival’s private destination strategy also factors into fuel management as Weinstein noted that investments in Caribbean destinations like Celebration Key and the forthcoming pier at Half Moon Key are deliberately sited close to homeports.
