Sustainability from ship to shore

Our commitment to the environment

P&O Cruises and our parent company Carnival Corporation take our environmental responsibilities very seriously and are committed to reducing our environmental impact. We are dedicated to preserving the marine environment in which we operate, and believe it is our duty to follow environmental practices which set a high standard of excellence and responsibility.

Our targets

Carbon footprint

Committed to sustainability and environmental protection in the communities we visit, we’ve effectively reduced our carbon footprint ahead of schedule with a 24.8% reduction in our equivalent CO₂ emissions. Combined with the first low carbon fuel powered ship – with another seven on order – and our Wärtsilä partnership to drive further engine efficiency, we’ll continue improving the quality of our air emissions.

We aim to reduce the intensity of CO2e (equivalent carbon dioxide) emissions from our operations by 25% by 2020 relative to our 2005 baseline.

Health, Safety and Security of Guests and Crew

Our commitment to the health, safety and security of guests and staff continues with new Zika virus prevention procedures and disinfection product efficiency testing against the Norovirus. The $500m investment to enhance ship safety and reliability, standardised security testing, occupational health and safety best practice roll out and piloting of new technologies all support this integral corporate objective.

Striving to be free of injuries, we continue to build on our commitment to protect the health, safety and security of our guests, employees and all others working on our behalf.

Exhaust Gas Cleaning Systems

On track with 59% of our fleet now equipped with Exhaust Gas Cleaning Systems (EGCS), we’ve continued to improve our emissions quality. With $400m investment, we’re leading the way to significant development of these limited marine application EGCS and environmental technology.

We aim to continue to improve the quality of our emissions into the air by developing, deploying and operating Exhaust Gas Cleaning systems across the fleet capable of reducing sulfur compounds and particulate matter from our ship’s engine exhaust.

Waste water purification

Our waste management plan specifies the responsible and efficient control, disposal, elimination and minimisation of the waste we generate, including water. We’re successfully on target with a waste water purification fleet-wide increased capacity of 3.3 percentage points, and remain committed to continued reduction utilising technologies to meet or exceed industry standards and regulations on board and in port.

We aim to increase Advanced Waste Water Purification System (AWWPS) coverage of our fleet wide capacity by 10 percentage points by 2020 relative to our 2014 baseline.

Shore power

Shore power target info-graphic

Ship shore power capacity is available on over 40% of our corporate fleet. Carnival is also working to secure increased availability elsewhere. We aim to increase shore power coverage of Carnival Corporation and plc's fleet-wide capacity in relation to future port capabilities.

Waste reduction

waste reduction info-graphic

Our recycling initiatives and partnerships have put us 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 donate items for reuse if suitable. All of our ships have on-board waste processing equipment to facilitate the segregation and correct packaging of waste for offload. Our supply chain works with suppliers to minimise packaging sent to the ships and our food and beverage teams work hard to ensure minimal waste is produced whilst delivering our guests expectations.

We want to continue to reduce waste generated by our shipboard operations by 5% by 2020 relative to our 2010 baseline, as measured by kilograms of non-recycled waste per person per day.

Ethics and Diversity

Recognised as a top employer for diversity and equality by the Human Rights Campaign and Black Enterprise Magazine, we continue to build an inclusive workforce. We’ve created a diversity council and published a slavery and human trafficking statement. Health, Environmental, Safety and Security is at the heart of all our operations.

We aim to continue to build a diverse and inclusive workforce and provide all employees with a positive work environment and opportunities to build a rewarding career to further drive employee engagement.

Water efficiency

Through investment in technologies such as reverse osmosis our ships are capable of producing more of the potable water required onboard without significant increases in energy usage. The use of efficient water production systems coupled with investment in water saving devices and raising awareness with our guests has enabled us to reduce our reliance on bunkering water in port.

We aim to continue to improve water use efficiency of our shipboard operations by 5% by 2020 relative to our 2010 baseline, as measured by liters per person per day.

Partner code of conduct and ethics

Suppliers info graphic

Supply chain compliance with our revised Business Partner Code of Conduct and Ethics continues with a new pledge to support human rights and the communities we visit through observance of the UK’s Modern Slavery Act. Supplier efforts to combat slavery and human trafficking – in addition to their business ethics, compliance and sustainability - are now also disclosed via our new Supplier Evaluation Questionnaire.

We aim to further develop and implement vendor assurance procedures ensuring compliance with Carnival Corporation & plc’s Business Partner Code of Conduct and Ethics.
