A world of beauty and wonder.

Our commitment to preserving the environment.

Cunard and our parent company Carnival Corporation and plc take our environmental stewardship very seriously and are committed to reducing our environmental impact.

Sustainability from ship to shore.

Across Carnival Corporation and plc’s 10 brands, we host over 11 million guests a year, visiting over 700 ports of call around the world. The health and vitality of the oceans, seas, and communities through which we travel are absolutely essential to our business. That makes protecting the environment one of our most critical areas of focus.

Our employees not only take great pride in making sure our guests’ vacation experience exceeds their expectations, but are also deeply committed to protecting the oceans and seas.

Safeguarding the environment.

Clean water.

Carnival Corporation and plc’s waste water discharge policies reflect those of the Cruise Lines International Association (CLIA), which are significantly more stringent than those required by international law.

With careful planning and strict adherence to these discharge requirements, Carnival aims to minimize impact, both on the ports we visit and within the areas we sail.

All three Cunard Queens have state-of-the-art advanced waste water treatment systems installed, ensuring all sewerage discharges exceed international requirements.

Cunard has also invested in ballast water treatment systems and has been a market leader in installing IMO and US Coastguard-approved technology to carry out biological disinfection. The ships’ ballast systems are independently tested on an annual basis by the Ballast Water Center to the full IMO D2 standard, to ensure that the treatment systems continue to do what they were designed for.


Together with our waste vendors and ports, Carnival Corporation and plc aims to minimize waste being sent for disposal. By evaluating shoreside waste facilities in advance, Carnival aims to manage any lack of recycling infrastructure by retaining waste materials on board until we reach a port offering the services we require when possible.

We seek new opportunities to reuse materials and equipment on board or find others who can use items that are in good condition. If this is not possible, we ensure conscientious disposal, including the use of certified recovery units for items such as refrigerators to reduce any Ozone Depleting Substance (ODS) releases.

We provide opportunities for our guests to assist our recycling efforts with segregated waste disposal. Through Carnival’s FATHOM - TRAVELdeep™ program during its first year, over 2,500 guests supported recycling entrepreneurship schemes in the Dominican Republic. Carnival’s crew - in particular those directly involved in waste management operations – is rigorously trained as part of their environmental awareness.

Single-use plastics.

Over the next few months, you may notice changes to some of our practices as we work to reduce single use plastics and eliminate other items which are difficult to recycle or separate from food waste. We are doing this to reduce our environmental footprint. It’s not about reducing costs and will in fact increase our costs and manpower required to implement these changes.

To give you an idea of what some of these changes may look like, below are some that we have already put in place or are in progress:

  • We have replaced single use plastic items like cotton buds, drinking straws and stirrers, and sail-away flags with more sustainable alternatives or reduced their use to ‘on request’ only.
  • We have completely removed the use of balloons.
  • We will remove the majority of single serve sachets and containers this year, for example sauce sachets, margarine and foil-wrapped butter, jam and other condiments, and yoghurt pots. They will be replaced with refillable dispensers or serving dishes.
  • We are also developing plans to drastically reduce the amount of plastic waste created by the toiletries provided to each stateroom and reduce our reliance on plastic water bottles.
  • Working closely with our suppliers, we are also striving to reduce food and beverage packaging and replace with recyclable or biodegradable alternatives.

Energy efficiency.

Fuel provides the energy for Carnival Corporation and plc ships’ propulsion and on-board hotel power requirements. Responsible for over 97% of emissions, fuel usage is the main contributor to Carnival’s carbon footprint.

Through the implementation of multiple energy-saving and conservation initiatives, Carnival has reduced emissions by 24.8% to date.

Our BSI ISO 50001 accreditation provides a framework for energy management, whilst our Corporate Energy Conservation Group has effectively reduced overall consumption and identified fuel-saving opportunities.

Carnival Fleet Operation Centers’ advanced data-capture systems keep us informed of the optimization and efficiency of motor conditions, emissions, fuel consumption and energy use.

Responsible sourcing.

The source of Carnival Corporation and plc’s supplies directly affects our communities and the environment, so it is vital we understand their providence and invest in sustainable development.

Our BSI ISO 14001:2015 certification requires sustainable resourcing, climate change mitigation and life-cycle management, from production to disposal. Carnival’s Business Partner Code of Conduct, coupled with the Ethics and Supplier Evaluation Questionnaire, provide a framework for suppliers to be aware of our expectations for ethics, compliance and sustainability.

Cunard works closely with them to implement eco-friendly initiatives, such as the use of recycled materials and minimal packaging, as well as the provision of responsible guest activities such as excursions.


The oceans and communities we visit boast spectacular biodiversity for guests to explore. Carnival Corporation and plc is committed to protecting the marine environment, minimizing impact and ensuring resources are used efficiently and sustainably.

We provide donations, volunteer initiatives - including coastal clean-up projects - and philanthropic programs. Carnival’s Fathom TRAVELdeep™ program has supported ventures including reforestation and food cooperatives.

We partner with conservation organizations in order to support programs related to our operations. Rutherford Appleton Laboratory, for example, has installed sea water temperature monitors on board Cunard’s Queen Mary 2, using the liner’s satellite link to provide data to the European Space Agency for climate change modeling.

Ethics and diversity.

Carnival Corporation and plc is an equal opportunity employer, hiring talented men and women for every position according to experience, skills, education and character. We have created a diversity council and are proud to be among the Human Rights Campaign’s top best places to work for LGBTQ equality for the third year, and we have also been recognized by Black Enterprise Magazine as one of the 50 best companies for diversity. Cunard itself has sponsored Southampton Pride in the United Kingdom for two years running.

Carnival’s 2020 targets.

Carbon footprint.

Committed to sustainability and environmental protection in the communities it visits, Carnival Corporation and plc has effectively reduced its carbon footprint in 2017 ahead of schedule. Carnival is investing in low-carbon, fuel-powered ships. And, in partnership with Wärtsilä (the marine industry’s leading solutions and services provider) to drive further motor efficiency, we’ll continue to improve the quality of our air emissions.

Exhaust gas cleaning systems.

On track, with 62% of the Carnival Corporation and plc fleet now equipped with Exhaust Gas Cleaning Systems (EGCS), they’ve continued to improve emissions quality. All three Cunard Queens have this technology in place. Carnival’s $400m investment sets us on course for significant development of these EGCS and environmental technologies.

Waste water purification.

Carnival Corporation and plc’s waste management plan specifies the responsible and efficient control, disposal, elimination and minimization of the waste we generate, including water. Carnival is on target - with an increased waste water purification capacity of 6.2 percentage points fleet-wide. All three Cunard Queens are fitted with advanced waste water treatment systems to ensure discharges are significantly cleaner than the standards required by the International Maritime Organization and others.

Shore power.

Ship shore power capacity is on course, with over 43% of Carnival Corporation and plc’s fleet – including Cunard’s Queen Mary 2 - now capable of using shore-based power when in port. On her current itineraries, Queen Mary 2 uses power from the local grid in New York and Boston, with Carnival ready to increase shore power coverage of its fleet-wide capacity in relation to future port capabilities.

Waste reduction.

Carnival Corporation and plc’s recycling initiatives and partnerships have stayed securely on track to reduce on-board operational waste by 5%. Where facilities exist, we aim to recycle as much of our waste as we can, or to donate it for reuse if suitable. Each Carnival ship has on-board waste-processing equipment to segregate and correctly package waste. Cunard’s supply chain works with suppliers to minimize packaging sent to the ships, and food and beverage teams work hard to ensure minimal waste is produced whilst still meeting guests’ expectations.

Water use efficiency.

While maintaining our water efficiency, Carnival Corporation and plc has successfully decreased its impact on ports, with an additional 4% now created from sea water, bringing us to 77% efficiency overall. Due to our ships’ holding capabilities, we adapt water-sourcing locations for the remainder, continue to upgrade water-dependent systems or equipment with more efficient options, and facilitate guests to embrace water conservation routines.

Diversity and ethics.

Carnival Corporation and plc has been recognized as a top employer for diversity and equality by both Black Enterprise Magazine and the Human Rights Campaign, and we continue to build an inclusive workforce. We have created a diversity council and disclosed a slavery and human trafficking statement.

Health, safety and security.

Carnival Corporation and plc has invested $500m to enhance ship safety and reliability. Carnival’s initiatives include standardized security testing, an occupational health and safety best-practice roll-out and the piloting of new technologies. Carnival’s commitment to the health, safety and security of guests and staff continues with new virus prevention procedures and disinfection product efficiency testing against Norovirus.

Code of conduct and ethics.

Suppliers’ compliance with Carnival Corporation and plc’s Business Partner Code of Conduct and Ethics continues, with a pledge to support human rights and the communities we visit through observance of the UK’s Modern Slavery Act. We also expect our business partners to adopt and incorporate these commitments into their organization.
