- Carnival Corporation has raised its emissions reduction target to 25pc by 2029
- The previous 20pc target was achieved five years ahead of schedule
- LNG-powered vessels and air lubrication systems are key to the strategy
- Fuel efficiency upgrades are projected to save $650m in costs
- The company aims for net-zero emissions from ship operations by 2050
Carnival Corporation has officially accelerated its climate roadmap, establishing a new target to cut its greenhouse gas emissions intensity by 25pc by 2029. This updated goal replaces the previous target of a 20pc reduction by 2030, which the world’s largest cruise company achieved five years ahead of schedule. The cruise operator has outlined measures aimed at lowering its environmental impact across its global fleet.
By hitting its previous benchmarks early, Carnival Corporation raised its target by five percentage points and pulled the deadline forward by a full year. The target utilises a 2019 baseline and is calculated on an available lower berth days basis, meaning the metrics track emissions intensity per passenger capacity rather than an absolute reduction in total fleet emissions. The 44pc overall reduction in emissions intensity achieved since 2008 relies on a multi-layered engineering stack. The company retired 27 older, less-efficient ships since 2019, deploying 11 liquefied natural gas powered vessels to replace them, with seven new-builds on order through 2033 engineered to be 20pc more efficient than current tonnage.
Air lubrication systems are being installed across the fleet to generate tiny air bubbles under hulls, cutting propulsion energy by 5pc, while Azipod propulsion systems further trim fuel use by up to 10pc. Upgraded Power Saver Packs are fitted on roughly 80pc of the fleet to automatically optimise lighting and HVAC loads. Smart itinerary planning, real-time weather routing, and AI-driven voyage optimisation ensure ships take the most fuel-efficient paths. According to statements by CEO Josh Weinstein, sustainability changes are functioning as bottom-line margin drivers rather than just compliance burdens, with fuel-efficiency upgrades projected to save the company $650m in fuel costs compared to 2019 levels. These steps represent interim phases of a larger decarbonisation programme aiming for full net-zero greenhouse gas emissions from ship operations by 2050.
