Carnival Corporation has raised its sustainability ambitions after achieving its previous greenhouse gas emissions intensity target five years ahead of schedule.
The world’s largest cruise company has announced a new goal to reduce greenhouse gas emissions intensity by 25% by 2029, measured against its 2019 baseline. The new target increases its previous ambition by five percentage points while bringing the deadline forward by one year.
The announcement follows Carnival’s achievement of a 20% reduction in greenhouse gas emissions intensity in 2025, meaning the company reached its original 2030 target significantly earlier than planned.
The progress has been driven by a combination of operational improvements, energy efficiency investments and the introduction of lower-emission technologies across its global fleet.
Carnival has been improving how its ships operate through smarter voyage planning, weather routing and itinerary optimisation, alongside technologies designed to reduce energy consumption. These include energy management systems, waste heat recovery and air lubrication systems that can help ships move more efficiently through the water.
Power Saver Packs, which incorporate measures such as HVAC upgrades, LED lighting and energy management technology, are now installed on around 80% of Carnival’s fleet. The company says these measures have helped reduce annual shipboard energy demand significantly compared with 2019.
Carnival is also expanding its use of lower-greenhouse-gas technologies. Its sustainability strategy includes LNG-powered vessels, shore power, biofuels and battery storage, reflecting the company’s approach of using a combination of technologies rather than relying on a single solution.
Shore power is becoming an increasingly important part of the strategy. Carnival says 74% of its fleet now has the capability to connect to local electricity grids while in port, allowing ships to reduce their reliance on onboard engines where suitable infrastructure is available.
The company is also continuing to introduce more efficient ships. Seven new vessels scheduled to join the fleet through 2033 are expected to deliver more than 20% greater efficiency per passenger than the ships they replace.
Importantly, the sustainability programme is also delivering commercial benefits. Carnival expects improvements in fuel efficiency to generate around $650 million in savings during 2026 compared with 2019 levels, demonstrating how environmental initiatives can also contribute to operational performance.
Since 2008, Carnival says it has reduced its greenhouse gas emissions intensity by 44%, cutting emissions associated with each guest sailing by almost half.
With its latest 2029 target, Carnival is now building on that progress rather than treating its previous achievement as a finishing point. The move highlights the growing role of sustainability, efficiency and technology in shaping the future of global travel and tourism
