The world’s largest cruise company, Carnival Corporation & plc (NYSE/LSE: CCL;NYSE: CUK) has released its 12th annual sustainability report, detailing the key initiatives and progress made in 2021 toward its 2030 sustainability goals and 2050 aspirations. It says that this latest sustainability report shows that the company is on track to meet its targets for 2030, while increasing initiatives to support its aspirations for 2050. Detailed below are key highlights and progress made through the end of 2021 under its six focus areas.


Carnival Corporation says it remains focused on decarbonization. The company and its brands are committed to continuing to reduce carbon emission intensity and have long-term aspirations to achieve net carbon-neutral ship operations by 2050. To achieve these goals, the company supports the adaptation of alternative fuels and is testing new technologies as they become available, developing and installing advanced air quality systems, and partnering with various organizations and stakeholders to support and accelerate its decarbonization efforts. 2021 sustainability highlights under the climate action focus area include:

  • Carbon Emission Goal: Carnival Corporation remains on track to achieve a 20% carbon intensity reduction by 2030 relative to its 2019 baseline, measured in both grams of CO2e per ALB-km and kilograms of CO2e per ALBD. To reaffirm and strengthen its initial carbon intensity reduction goals for 2030, the company has updated the baseline year for both goals to 2019 from a 2008 baseline.
  • Shore Power: As of the end of 2021, 46% of the company’s fleet was equipped with shore power capabilities, enabling ships to use shoreside electric power where available while in port.
  • Liquefied Natural Gas (LNG): As part of its goal to expand its LNG program, the company introduced additional LNG ships to the fleet in 2021, for a total of six cruise ships currently in operation with the ability to be powered by LNG.
  • Advanced Air Quality Systems (AAQS): As of the end of 2021, 90% of the fleet (excluding LNG ships) was equipped with AAQS, capable of removing nearly all sulfur from exhaust, enabling cleaner air emissions at port and at sea with no negative impact to the marine environment.
  • New Technologies: The company is investing in a first-of-its-kind lithium-ion battery storage system, installing hull air lubrication systems, testing fuel cells powered by hydrogen derived from methanol, and exploring carbon capture and storage.

Carnival Corporation and its brands are also shifting how the company works with its supply chain partners to reduce waste. 2021 highlights under the circular economy focus area include:

  • Reducing Single-Use Plastics: Achieved goal of reducing single-use plastic items by 50%, despite the pandemic and the need to continue using many of these type of items for public health and sanitation purposes.
  • Food Waste Reduction: Achieved a 24% food waste reduction per person in 2021, making great progress toward its 2022 goal of a 30% food waste reduction per person and its 50% food waste reduction per person by 2030.
  • Biodigesters: As of the end of 2021, the company completed the installation of over 500 biodigesters throughout its fleet, in support of ongoing food waste management efforts.
  • Advanced Waste Water Treatment Systems (AWWTS): Carnival Corporation remains on track to achieve its goal of increasing AWWTS coverage to over 75% of its fleet capacity, with 59% coverage of its fleet capacity as of the end of 2021.

Carnival Corporation says it remains focused on expanding its well-being programs to support the physical and mental health of its employees, encouraging social connectivity with family and friends, and promoting a balanced lifestyle. Health and well-being efforts in 2021 include:

  • Employee Outreach and Well-Being: Increased focus on employee outreach and wellness, as it relates to the unique needs of shoreside and shipboard employees.
  • Job Creation: Increased the number of employees on board a number of its ships from reduced levels during the pause in guest cruise operations, in addition to opening a significant number of shoreside positions.
  • Company Culture Metrics: As part of its ongoing effort to establish measurable company culture metrics and set annual improvement targets, in 2021 the company continued an employee survey program and introduced training sessions and internal communications designed to promote its “Culture Essentials” program focused on further strengthening corporate culture.
  • CSMART Academy Training Update: During 2021, the CSMART Academy – officially the Center for Simulator Maritime Training Academy, part of the Arison Maritime Center – continued to provide online and onboard training to the fleet while also advancing preparations for the restart of onsite training in 2022. The CSMART team has made advances in developing and delivering online curriculum through courses, tailored events such as remote ‘’newbuild training,’’ and through ongoing webinars.


As a global company, Carnival Corporation says that it and its brands recognize the collective responsibility to respect and help maintain the culture, history and natural resources of the communities in which it operates. 2021 highlights under the sustainable tourism focus area include:

  • Disaster Relief: Supported disaster relief efforts to the victims of the La Soufrière volcano eruption in St. Vincent and the Grenadines, as well as communities in Barbados impacted by volcanic ash.
  • Destination Partnerships: The company’s Italy-based Costa Cruises kicked off its “Traditions in the Future” project, which supports the preservation of traditional arts and crafts to a new generation of artisans.

Additionally, in 2021 the company’s European brands donated over 20 tons of food items to address hunger throughout communities in need, in partnership with three regional initiatives, including the European Foodbank, UK Harvest and the Banco Alimentare.
