As mariners on the world's oceans, we at Celebrity Cruises know we have a special obligation to protect our environment.  The sustainability of our planet is dependent on clean seas and pure air.  It is central to our guests' vacation experience, and is at the core of our commitment to continually improve our environmental stewardship practices.

Environmental Stewardship

A Journey to Zero Waste

We are working to achieve zero waste across our fleet. Today, through our “Green Hub” waste vendor program, 85% of our waste is recycled, repurposed or sent to a waste-to-energy facility. Our fleet boasts state-of-the-art facilities, complete with shredders, bailers and compactors that allow us to divert 100% of our waste from a landfill where port facilities permit.

Shore Power

Shore Power allows our ships to reduce in port emissions to near zero when at a port with connectivity. Four ships in our fleet are currently equipped with shore power technology, allowing them to use power from the local electrical grid while docked at port, instead of burning fuel. Each new Celebrity ship we introduce moving forward will be equipped with shore power.

Edge Series

Our Edge series is equipped with several features that reduce fuel consumption by 20% compared to our previous generation of ships. Other features include Emissions Purification Systems removing approximately 98% of Sulphur Dioxide emissions and Selective Catalytic Reduction systems which remove 97% of Nitrogen Oxide emissions. 


We’re replacing higher wattage halogen and incandescent light bulbs with longer lasting fluorescent and Light Emitting Diode (LED) lights throughout our fleet. Fluorescent and LED bulbs require 80% less energy, generate 50% less heat, reduce energy consumption, last much longer and contribute to more efficient air conditioning due to the cooler bulbs.

Renewable Energy Sources

Our industry leading Solstice series launched in 2008 with the first-ever cruise vessel to feature solar power technology on board. The panels and the clean power they produced helped reduce the consumption of energy derived from fossil fuels.

High-Efficiency Appliances

We have installed high-efficiency appliances throughout the ship in order to minimize their impact on climate change and reduce our energy load. Every type of appliance onboard our ships is being evaluated for efficiency, including TV's, coffeemakers, ice makers, ovens and dishwashers.

Energy-Efficient Windows

Across the fleet we have applied window films that are specially glazed to prevent solar heat from penetrating, thereby reducing the amount of air conditioning needed to cool the ship, thereby saving energy.

Hull Coatings

We apply new silicone paints on the hull, which are innovative and environmentally safe coatings that increase the smoothness of our ships' hull. By creating a smoother hull, we can reduce the amount of energy needed to travel through water.

Propulsion and Hull Design

A new approach to hull design and propulsion systems, resulted in significant energy savings. Ships equipped with Common Rail Diesel Engines reduce energy consumption and NOX emissions at all engine loads.

Heating, Ventilation, and AC

Our ships are equipped with the latest and most efficient air-conditioning equipment commercially available. Coupled with improvements in system design and automation.

Operation Conservation Measures

Our environmental policies guide both our shipboard and shoreside employees in beneficial environmental practices. Our crewmembers are an integral part of our energy-conservation efforts. Staff and guests are advised to turn off lights, water and appliances when not needed, adjust temperature thermostats to comfortable levels when no one is present and using towels and bed linens more than once before laundering.

Fresh Water Consumption

We ask our crewmembers and guests to help us conserve water whenever possible. To help reduce the energy needed to produce fresh water, we have installed water-reduction technology and appliances throughout our fleet to reduce the use of water-producing equipment that consumes fuel or electricity. These features include sink aerators, showerheads, reduced-flow dishwashers and low-consumption laundry equipment.

Advanced Wastewater Purification

We installed Advanced Wastewater Purification (AWP) systems throughout the fleet. These technologically advanced systems are designed to clean the wastewater generated onboard our ships to create clean water that exceeds ship wastewater discharge standards throughout the world and meet EU treatment standards. We produce up to 90% of the fresh water on board our ships.

Our responsibilities as a steward of the environment are central to our mission as a corporation. The environment is critical to our success. As a company, we have a history of innovation in the industry. We are equally proud of our reputation as a leader in protecting the environment. Celebrity Cruises values the environment and is committed to protecting and preserving environmental resources, preventing pollution and continually improving environmental management.
