Carnival Corporation released its 13th annual sustainability report, detailing industry-leading initiatives and momentum across environmental, social and governance focus areas, according to a press release.

The report also describes significant progress made by the company toward its aspirations of carbon neutral operations by 2050 and a circular economy model focused on waste reduction, recycling and management. Titled “Sustainable from Ship to Shore,” Carnival Corporation’s full 2022 report is available on the company’s sustainability website at

“As the global leader in the cruise industry, we are setting the pace with the industry’s smartest solutions for sustainable cruising that will help deliver on our aggressive roadmap to reduce our carbon impact, maximize our use of resources and further enhance our operations to be even more efficient by 2030,” said Josh Weinstein, CEO and chief climate officer for Carnival Corporation. “Our future depends on us being good corporate citizens and stewards of the environment, because without the incredible communities, healthy marine ecosystems, and scenic spaces we operate in, it would be impossible to deliver unforgettable happiness to our guests through extraordinary cruise vacations.”

Carnival Corporation said that it remains the only major cruise operator producing fewer greenhouse gas (GHG) emissions today than in 2011, despite adding substantial guest capacity to its fleet since that time. The company is on track to achieve a 40% reduction in carbon intensity by 2030 (vs. 2008), and a 20% reduction in carbon intensity by 2030 vs. 2019, resulting from strong momentum in its four-part decarbonization strategy: fleet optimization; energy efficiency; itinerary efficiency; and new technologies and alternative fuels. Collectively, these strategic initiatives are expected to drive a 15% reduction in fuel consumption per available lower berth day (ALBD) in 2023, along with a 15% reduction in emissions per ALBD, both relative to 2019.

Additionally, the company completed its first inventory of Scope 3 “value-chain” emissions associated with purchased goods and services, fuel and energy distribution/delivery, and waste management, among others. Using the GHG Protocol standard, in the future, the company will track these emissions annually vs. a full-year 2019 operations baseline.

Other 2022 decarbonization highlights include:

Investing in Energy-Efficient Solutions:

  • Service Power Packages: Continued the fleetwide rollout of eco-friendly upgrades (LED lights, HVAC automation, variable speed drives on pumps and fans, etc.) for an average 5% fuel consumption savings per ship, and expected to generate over $100 million in annual fuel cost savings upon completion).
  • Shore Power: 57% of the global fleet is now able to “plug in” to reduce emissions and noise in port where connections to electric power are available.
  • Air Lubrication Systems (ALS): Expanded this technology to more ships to help them glide on air bubbles with ~5% less friction, for fuel consumption savings and reduced emissions (five ships installed, six in progress and eight on order).

Pioneering New Technologies & Alternative Fuels:

  • Liquefied Natural Gas (LNG): Leading the industry in new fuel propulsion with eight LNG-capable ships in service with three more on order to account for 20% of fleet capacity by 2025.
  • Batteries & Fuel Cells: Piloting the world’s largest ever battery installation on a passenger ship with a first-of-its-kind lithium-ion battery storage system on AIDAprima and pioneering a new generation of power in the industry with fuel cell technology using methanol-derived hydrogen on AIDAnova.
  • Biofuels: Leading the industry in piloting biofuels as a replacement for fossil fuel with successful trials on AIDAprima and Holland America Line’s Volendam.
  • Partnerships: Driving decarbonization pathways for the industry as part of the Mærsk Mc-Kinney Møller Center for Zero Carbon Shipping, Getting to Zero Coalition and Methane Abatement in Maritime Innovation Initiative, among others.

Shrinking the Company’s Food Print:

  • Surplus Food: Achieving per-passenger food waste reduction of more than 30% in 2022 (vs. 2019) and establishing a new goal to reduce food waste by 40% per person by 2025.
  • Biodigesters: Leading the industry with over 600 food biodigesters installed on ships to break down and liquify uneaten food and sustainably return it to nature.
  • Dehydrators: Installing 25-plus food dehydrators across the fleet to remove excess water from leftover food, reducing waste volume by upwards of 90%.
