Environmental Protection and Stewardship

Cruise Lines International Association (CLIA) oceangoing Members (CLIA Members) recognize that responsible operational practices are fundamental to the protection of the environment. To this end, CLIA Members demonstrate their commitment to protecting the environment through the adoption of policy, the use of innovative technologies, and the development of best practices which frequently go above and beyond those international, national, state, and local requirements which apply to all oceangoing ships.

Examples of how CLIA Members demonstrate their commitment to the environment include:

The cruise industry has advocated policies and best practices for the management of air emissions, all waste streams produced onboard including oily bilge and sludge, solid, hazardous, and special wastes, and discharges of water, including graywater, sewage, and ballast water.

To the extent there are any environmental practices and procedures not described herein, CLIA Members are to comply with all local, state, national, and international environmental requirements in the areas in which they operate. In addition to existing regulatory requirements, CLIA Members have voluntarily agreed to adopt the commitments set forth in this Policy in their respective Safety Management Systems (SMS) / Environmental Management Systems (EMS). These often exceed legal requirements during normal operations ⁹. CLIA Members welcome the development of advanced and sustainable technologies and new responsible environmental practices. As appropriate, such practices and procedures may be included as a future revision to this document.

This document is organized as follows:

International Maritime Organization (IMO) Conventions:
The following IMO Conventions represent a small sample of requirements that are applied to the operations of oceangoing cruise passenger ships

MARPOL
The International Convention for the Prevention of Pollution from Ships (MARPOL) is a foundational international agreement aimed at minimizing pollution from ships. It consists of six annexes, each covering a different type of pollution. Not all annexes apply to cruise ships; those which are applicable are summarized below.

MARPOL Annex I: Prevention of Pollution of Oil
Annex I addresses oil pollution prevention. It mandates the use of oil discharge monitoring and control systems, oily water separating equipment, oil filtering systems, and oil content meters to ensure proper management of oil and bilge water, thereby preventing contamination of the marine environment.

MARPOL Annex IV: Prevention of Pollution by Sewage from Ships
Annex IV establishes requirements for controlling sewage discharge into the sea, requiring ships to have approved sewage treatment plants, sewage comminuting and disinfecting systems, or holding tanks.

MARPOL Annex V: Prevention of Pollution by Garbage from Ships
Annex V regulates the management and disposal of garbage generated during a ship's normal operations, specifying record-keeping requirements, and the implementation of garbage management plans. It categorizes types of garbage and prescribes specific procedures for handling each type to prevent marine litter.

MARPOL Annex VI: Prevention of Air Pollution from Ships
Annex VI limits air pollutants emitted from ships, including Sulfur Oxides (SOx) and Nitrogen Oxides (NOx), and prohibits the deliberate release of ozone-depleting substances. It also regulates shipboard incineration. Additionally, Annex VI is subject to amendment to incorporate IMO Member State commitments to limit Carbon intensity and overall Greenhouse Gas (GHG) emissions from international shipping.

Ballast Water Management Convention
The International Convention for the Control and Management of Ships’ Ballast Water and Sediments (BWM Convention) aims to prevent the spread of harmful aquatic organisms from one region to another by establishing procedures for the management and control of ships’ ballast water and sediments.

Hong Kong Convention
The Hong Kong International Convention for the Safe and Environmentally Sound Recycling of Ships aims to ensure that ships at the end of their operational life do not pose any unnecessary risk to the environment or to human health and safety when being recycled.

Anti-fouling Systems Convention
The International Convention on the Control of Harmful Anti-fouling Systems on Ships prohibits the use of harmful pollutants in anti-fouling paints used on ships.

CLIA Member Environmental Policies and Best Practices

• Air

  Greenhouse Gases

  Greenhouse Gas Emissions Reduction

  CLIA Members have committed to reducing the rate of carbon emissions as an average across the industry fleet by 40% by 2030, using 2008 as the baseline year, and to pursue net-zero emissions by 2050. The cruise industry’s decarbonization ambition can be accomplished through a blend of improving energy efficiency through conservation, optimization, and energy management, and transitioning to lower-carbon fuels. CLIA Members have demonstrated their commitment to these measures through continued investment in, and adoption of, sustainable technologies.

  Further energy efficiency mechanisms are detailed below.

  Energy Efficiencies

  In addition to setting limits for various emissions from ship exhausts and prohibiting deliberate emissions of ozone-depleting substances, MARPOL Annex VI provides the international standard for technical and operational measures to reduce greenhouse gas emissions through energy efficiencies as detailed in the ship’s energy efficiency management plan. Some elements of this plan may include:

  • Voyage Optimization
  • Shipbuilding – Technology and Design
  • Hull Cleaning
  • Onshore Power Supply (OPS) / Shoreside Electricity (SSE)

  CLIA Members continue to expand shore power capabilities, allowing ships to turn off engines while in port and utilize shoreside power systems when available. The objective of expanding onshore power availability and capacity of power sources and interfaces at ports provides an opportunity for advocacy and cooperation with port operators that could influence broader adoption of onshore power capabilities by other shipping industry participants.

  Furthermore, CLIA Members commit that, by 2035, all member-operated ships calling at ports where shoreside electricity (SSE) is available will be equipped to use SSE or be able to use alternative low-carbon technologies in port, as available.

  Regional Decarbonization Initiatives and Partnerships

  CLIA Members participate in various regional decarbonization initiatives, partnerships, and coalitions toward their climate objectives. These initiatives aim to promote decarbonization and sustainable shipping practices, reducing environmental impacts through collaboration among stakeholders who work cooperatively to implement technological, economic, and regulatory solutions to zero-emission shipping.

  Green Corridors are an example of such initiatives. These are maritime routes between two (or more) specified ports with the necessary fuel delivery infrastructure, technologies, safety standards, and economic incentives, supported by stakeholder commitment to facilitate the trial and early deployment of low- and zero-emission lifecycle fuels.

  Reduction of Sulfur Oxides (SOx)

  To reduce sulfur emissions into the air, MARPOL Annex VI sets sulfur limits and allows for the use of equivalent fittings, materials, appliances, or apparatus to be fitted to a ship, or other procedures, alternative fuel oils, or compliance methods as alternatives to the required standards.

  CLIA Members manage SOx emissions by using either low-sulfur fuels or alternative technology to reduce the amount of sulfur in their emissions. One such technology is an Exhaust Gas Cleaning System (EGCS). EGCS can reduce the levels of SOx in a ship’s exhaust by as much as 98%, while also reducing particulate matter (PM) and Nitrogen Oxides (NOx). Liquefied natural gas (LNG) and other future fuels also achieve SOx reductions and are discussed further in the “Future Fuels” section.

  Reduction of Nitrogen Oxides (NOx)

  CLIA Members must comply with the tiered NOx reduction criteria outlined in MARPOL Annex VI Regulation 13, which vary depending on ship construction date and engine speed.

  CLIA Members are evaluating various technologies and strategies for reducing NOx. LNG and other future fuels also achieve NOx reductions and are discussed further in the “Future Fuels” section.

  Opacity/Visible Emissions

  Consistent with regional or local programs and requirements, CLIA Members monitor visible emissions and take corrective action in the event of excessive visible emissions.

  CLIA Members actively collaborate with regulatory agencies to evaluate technological solutions to consistently monitor visible emissions.

  Future Fuels

  To address long-term environmental challenges and promote the adoption of next-generation fuels, CLIA Members participate in several alternative fuel initiatives around the world. While supply, safety, engineering, and regulatory challenges need to be addressed before large-scale adoption of these fuels can take place, the cruise industry’s involvement in facilitating the research and development of these fuels has accelerated technological advancements in these areas and shortened the expected timeline to overcome these barriers. CLIA Members also collaborate with fuel suppliers and other maritime stakeholders to advance the development and uptake of next-generation fuels.

  Alternative fuels already in use such as LNG provide immediate carbon emission reductions by up to 20% compared to traditional fuels, fulfill NOx tier requirements by cutting NOx emissions by up to 90%, and almost completely remove SOx emissions and particulate emissions, without the use of additional technologies. Methanol, and other future fuels under consideration, also offer reductions in these areas.

• Water

  Shipboard Water Production

  CLIA Members produce the majority of their freshwater needs using onboard desalination and water purification systems. This reduces dependency on local water resources, which is particularly important when visiting regions with limited freshwater availability.

  Through advanced technologies and practices, cruise ships efficiently manage water usage and promote conservation. This may include using water-saving galley and bathroom fixtures and implementing strict water management protocols.

  Wastewater

  CLIA Members recognize the sensitivity of discharging wastewater and must follow international, national, and local requirements in planning wastewater (sewage and graywater) discharges where permitted. CLIA encourages the provision of adequate shoreside reception facilities for wastewater where discharge is a concern.

  Wastewater Minimization and Reclamation

  Management of water use on a cruise ship is extremely important and includes minimizing water usage and reclamation and reuse of water for non-potable purposes. CLIA Members use various advanced technologies, practices, and techniques to minimize water use and promote conservation, including, but not limited to:

  • Use of water-saving equipment and systems (e.g., reduced flow bathroom fixtures, vacuum systems for toilets, vacuum food waste transportation, and reduced flow laundry and galley equipment).
  • Implementation of water recovery systems and processes (e.g., filtering and reuse of laundry water and air conditioning condensate in systems that do not require potable water, such as flushing toilets, laundry operations, and open deck washing).
  • Training and educating crew to conserve water, turn off faucets, close valves when not in use, and use only necessary quantities of water for cleaning purposes.

  Sewage (also known as Blackwater)

  Sewage includes water and waste from toilets or urinals and wastewater from medical areas (dispensary, sick bay, etc.). CLIA Members are to process all sewage through a sewage treatment plant certified in accordance with international requirements, prior to discharge during regular operations. For ships not able to use onshore reception facilities, and those who routinely navigate beyond the territorial waters of coastal states, treated discharges are permitted only when the vessel is more than 4 nautical miles from the nearest land and traveling at a minimum speed of 6 knots¹⁰, except in emergencies or due to geographic or technical constraints¹¹.

  Advanced Wastewater Treatment Systems

  To improve environmental performance, many CLIA Members have installed advanced wastewater treatment systems (AWTS) that utilize advanced tertiary-level treatment. These systems produce effluent discharges that meet and often exceed regulatory standards, sometimes producing better quality effluent than shoreside treatment plants and are therefore not subject to the CLIA sewage policy discharge limitations noted above.

  Bio-residues

  Bio-residue is the residual generated by an AWTS. Bio-residue is either landed to a shoreside reception facility, dried and incinerated onboard, or discharged in accordance with applicable legal requirements.

  Graywater

  Graywater refers to wastewater incidental to the operation of the ship, typically including water from galleys (food preparation, dishwashing, and cleaning), showers and sinks, and laundries.

  At a minimum, CLIA Members discharge graywater only when the ship is underway and proceeding at a speed of not less than 6 knots¹². and at a distance not less than 4 nautical miles from the nearest land, except in an emergency or due to geographic or technical limitations¹³.

  Ballast Water

  Ballast water is seawater taken up by the ship to maintain stability. Proper management of ballast water is critical to avoid the introduction of invasive aquatic species, which can result in irreversible ecological impacts. In accordance with the Ballast Water Management Convention and its related guidelines, CLIA Members are to maintain and implement Ballast Water Management Plans onboard each vessel and have either installed type-approved Ballast Water Treatment Systems (BWTS) or introduced ships that do not require ballast water to ensure stability at sea.

  Bilge and Oily Water Residues

  CLIA Members must meet or exceed international requirements for removing oil from bilge and wastewater prior to discharge to sea. The bilge is the lowest point in the ship, usually in the engine room, where water can collect from various sources. Oily bilge water is water which may be contaminated by oil resulting from things such as leakage or maintenance work in machinery spaces.

  CLIA Members must meet or exceed international requirements for removing oil from bilge and wastewater prior to discharge to sea. The bilge is the lowest point in the ship, usually in the engine room, where water can collect from various sources. Oily bilge water is water which may be contaminated by oil resulting from things such as leakage or maintenance work in machinery spaces.

  Any water in the bilge system (including bilge wells, bilge piping, tank top, or bilge holding tanks) is treated as oily bilge water. Bilge water is periodically pumped into holding tanks and treated through an approved oily water separator (OWS) to remove oil or reduce oil content below the MARPOL threshold prior to discharge to sea.

  Any oil removed from the bilge water is held onboard for reuse or landed to a port reception facility. Although MARPOL Annex I allows the discharge of clean bilge water at any distance from land, CLIA Members have agreed not to discharge processed clean bilge water within 12 nautical miles from shore.

  Some CLIA Members utilize a specialized type of bilge monitoring device, designed with enhanced features for compliance and data integrity, sometimes known as a "white box."

  In compliance with applicable national and international oil pollution rules, all international oceangoing vessels, including CLIA Members’ ships, must maintain an Oil Record Book, detailing all transfers and discharges of oil and oily liquids, including fuel oil, lubricating oil, waste oil, oily sludge, bilge water, and any other waste streams that end up in the bilge. The Oil Record Book is always available to any inspecting maritime authority in any port.

  Biofouling

  CLIA Members typically maintain Biofouling Management Plans, which include strict monitoring and maintenance requirements and the use of anti-fouling paint to prevent bio-growth on ships’ hulls and reduce the spread of invasive species.

  Deck and Hull Cleaning

  CLIA Members are to use non-ecotoxic and non-bio accumulative MARPOL and/or U.S. EPA Vessel General Permit-compliant cleaning products for deck and side shell washing. CLIA Members must perform regular inspections and cleaning of their vessels in accordance with regional and international requirements.

  Marine Mammal Protection

  CLIA Members implement operational measures to avoid marine mammal disturbance and report sightings and other activities to appropriate local authorities. CLIA Members recognize the importance of protecting marine mammals and are committed to promoting a sustainable future by following measures to protect species critical to the health of the ocean.

  CLIA Members work alongside port authorities and local wildlife experts to develop species-specific strategies when appropriate. Examples of marine mammal protection measures voluntarily followed by CLIA Members may include:

  • In specified areas in the northeast Gulf of Mexico, cruise lines maintain a vigilant lookout from the bridge for Rice’s whales, train bridge officers on whale ship strike prevention, voluntarily reduce speed to under 10 knots (when navigationally safe to do so) when whales are spotted, and report whale sightings to local authorities.
  • Along the coast of California, cruise lines participate in the Blue Whales and Blue Skies voluntary vessel speed reduction program from mid-May to December to coincide with whale feeding and migration.
  • Off the southern coast of British Columbia, cruise lines participate in the Enhancing Cetacean Habitat and Observation (ECHO) Program, which includes measures to protect killer whales, humpback whales, fin whales, blue whales, and sei whales.
  • Cruise lines participate in regional initiatives, such as the Charter on Sustainable Cruising in the French Mediterranean, which includes several commitments to protect the marine environment.
  • When operating in polar regions, cruise lines voluntarily share, with other ocean users, information related to vessel positions, marine mammal sightings, and marine mammal movements.

  ¹⁰ For ships operating under sail, or a combination of sail and motor propulsion, the speed shall not be less than 4 knots

  ¹¹Geographic limitations include special circumstances where a ship is operating in internal waters or shoreward of a territorial sea baseline for an extended period of time, in which case any applicable requirements will be controlling.

  ¹²For vessels operating under sail, or a combination of sail and motor propulsion, the speed shall not be less than 4 knots.

  ¹³Geographic limitations include special circumstances where a ship is operating in internal waters or shoreward of a territorial sea baseline for an extended period of time, in which case any applicable requirements will be controlling.

  Solid Waste Management: Waste Collection, Separation, and Processing

  Waste Management Practices

  CLIA Members have agreed to establish comprehensive procedures in their specific waste management plans, in accordance with MARPOL Annex V, that drive the safe and hygienic collection, minimization, separation, and processing of wastes onboard, and delivery to approved shoreside waste reception facilities. CLIA Member waste management plans also include actions and processes intended to minimize waste sent to landfills. In the regulation, the term “garbage” includes all kinds of food wastes, domestic wastes, operational wastes, plastics, cargo residues, incinerator ashes, and cooking oil generated during the normal operations of the ship, except those substances defined or listed in other Annexes to the present Convention. In line with MARPOL Annex V, CLIA Members agree to manage garbage in accordance with the requirements contained in the following:

  Cooking Oil

  Cooking oil means any type of edible oil or animal fat used or intended to be used for the preparation or cooking of food but does not include the food itself that is prepared using these oils. Waste cooking oil is typically strained to remove debris and then collected and landed ashore. Alternatively, it may be incinerated or burned as fuel to make steam or electricity onboard as local requirements allow.

  Food Waste

  Food wastes mean any spoiled or unspoiled food substances and include fruits, vegetables, dairy products, poultry, meat products, and food scraps generated aboard the ship. CLIA Members strive to reduce the amount of waste generated onboard, including food waste, and waste is disposed of in accordance with MARPOL Annex V or applicable local requirements.

  Domestic Waste

  Domestic waste means all types of wastes not covered by other Annexes that are generated in the accommodation spaces onboard the ship. Domestic waste does not include graywater.

  CLIA Members have installed equipment (compactors, shredders, incinerators, biodigesters, etc.) to assist with sorting and reducing the volume of the waste, which in turn reduces the storage space required and results in more efficient offloading and recycling programs. Paper, cardboard, and other materials are to be recycled when local recycling facilities are available shoreside, but some volume of combustibles may be incinerated onboard for operational reasons.

  Glass bottles, jars, and other glassware are crushed for recycling when feasible. Some CLIA Members separate glass by color to further increase the recycling potential of the waste stream. Aluminum (soda cans and deck chairs), galley tins, and other metals (copper, brass, bronze, Cu-Ni, and scrap steel) are separated by type and landed ashore for recycling where local recycling facilities exist.

  Incinerator Ash

  Incinerator ashes mean ash and clinkers resulting from shipboard incinerators used for the incineration of garbage.

  Incinerator ash is landed ashore in accordance with applicable local and national requirements. CLIA Members using incinerators agree to test incinerator ash at least annually for hazardous components, using an internationally accepted testing standard.

  Operational Waste

  Operational waste includes all solid waste not covered by other Annexes that are collected onboard during normal maintenance or operations of a ship. This includes cleaning agents and additives contained in external wash water but does not include graywater, bilge water, or other similar discharges essential to ship operations.

  Some operational waste may be considered harmful substances requiring special handling (referred to as "hazardous waste" in some jurisdictions). CLIA Members must appropriately categorize and land all waste of this nature in accordance with local requirements.

  Drycleaning Waste

  Depending on the type of solvent used, shipboard drycleaning facilities may produce a small amount of waste, including dirt, oils, filter material, and spent solvent. This waste may be classified as hazardous or special waste and is only disposed of ashore in accordance with local requirements.

  Some CLIA Members have replaced solvent-based dry-cleaning equipment with systems using non-toxic solvents. Others have installed “wet cleaning” processes that do not use solvents and therefore do not produce hazardous waste.

  Electronic Waste (E-waste)

  Electronic waste (E-waste) includes electrical and electronic equipment used in the normal operation of the ship or for personal use in the accommodation spaces, including all components, subassemblies, and consumables. E-waste contains low levels of toxic heavy metals such as arsenic, barium, cadmium, chromium, lead, mercury, silver, and selenium.

  CLIA Members collect used electronic equipment generated onboard and partner with responsible vendors known to properly handle this waste. E-waste accepted for recycling includes:

  • Computer monitors and televisions
  • Personal computers, keyboards, hard drives, printers, and printer cartridges
  • Audio and video equipment
  • Communication equipment such as cellular telephones and handheld radios
  • Smoke detectors (non-ionizing)

  Photo Processing Liquid Waste

  CLIA Members agree to prevent the discharge of silver into the marine environment. This can be achieved by processing their liquid photo waste onboard through a silver recovery unit. Photo liquid waste is not discharged overboard, nor is it commingled with any other wastewater. CLIA Members regularly test photo liquid waste for presences of silver and land this waste stream to shoreside reception facilities, to be handled in accordance with local requirements.

  Many CLIA Members have installed digital X-ray and photo processing alternatives to further reduce the generated volume of this waste.

  Photocopying and Laser Printer Cartridges

  CLIA Members use only ink, toner, and printing/copying cartridges that are not known to contain hazardous chemical components. Where possible, these are returned to the supplier or an alternative facility for recycling and reuse.

  Print Shop Waste Fluids

  CLIA Members ensure that all print shop waste fluids, such as solvents and cleaning solutions, are managed and disposed of in accordance with applicable local, national, and international requirements. Hazardous components are handled with special care to prevent environmental contamination.

  Pharmaceuticals

  Each ship stocks an inventory of pharmaceuticals in their medical centers. All pharmaceuticals are managed to optimize efficacy and disposed of as needed in an environmentally responsible manner, employing one or more of the following practices:

  • Establishing a reverse distribution system for returning unexpired, unopened non-narcotic pharmaceuticals to the original vendor.
  • Appropriately destroying narcotic pharmaceuticals onboard the ship, in a manner that is witnessed and recorded.
  • Offloading listed pharmaceuticals in accordance with local requirements. Listed pharmaceuticals are hazardous wastes with chemical compositions that prevent them from being incinerated or disposed of through the ship’s wastewater treatment plant.
  • Disposing of other non-narcotic and non-listed pharmaceuticals through onboard incineration or landing ashore.

  Fluorescent and Mercury Vapor Lamp Bulbs

  Fluorescent and mercury vapor lamps contain small amounts of mercury that could potentially be harmful to human health and the environment. To prevent human exposure and contamination of the environment, these lamps are handled in an environmentally safe manner.

  CLIA Members agree to prevent the release of mercury into the environment from spent fluorescent and mercury vapor lamps through proper recycling or by using other acceptable means of disposal. The intact lamps are collected onboard in such a way to prevent breakage and are offloaded ashore as universal non-hazardous waste.

  Broken fluorescent or mercury lamps are carefully collected onboard in sealed containers, classified and offloaded ashore as hazardous waste, in accordance with applicable requirements.

  Other Mercury-Containing Products

  Where practicable, CLIA Members reduce the use of mercury-containing products. Products containing mercury are to be landed ashore as hazardous or special waste, as appropriate.

  Batteries

  Most of the large batteries found onboard are used in Uninterruptible Power Supply (UPS) systems, in lifeboats, tenders, and standby generators. Small batteries used in flashlights, microphones, communication devices, and other equipment, as well as by passengers’ personal use, account for the rest.

  CLIA Members collect spent batteries and return them for recycling whenever practicable or dispose of them in accordance with prevailing requirements. Discarded batteries are isolated from other waste. The wet-cell battery recycling program is kept separate from the dry-cell battery collection process. Intact wet-cell batteries are returned to the supplier when possible, while dry-cell batteries are landed to a licensed firm for recycling.

  Plastics

  CLIA Members continuously research ways to reduce the amount of plastic sent to landfills through sourcing, increasing recycling volumes, and dramatically reducing the purchase and consumption of non-essential single-use plastics.

  IMO Guidelines for the Implementation of MARPOL Annex V stipulate that shipowners and operators minimize bringing materials onboard that could become garbage. As such, they are encouraged to avoid supplies packaged in plastic unless such products are reusable or utilize reusable plastic. Examples of products to be avoided include disposable cups, utensils, dishes, towels, rags, and other convenience items.

  Ship Recycling

  CLIA oceangoing members recognize that proper ship recycling is fundamental to the safety of personnel, protection of the environment, and proper waste management policies. Therefore, CLIA Members agree to only use facilities meeting best-in-class standards for recycling retired ships, further supporting the commitment to a sustainable cruise industry.

  CLIA Members will recycle their ships according to established global standards regardless of flag, ownership, or operational area. Regardless of the location of the recycling facility, CLIA Members further agree, at a minimum, to require that the facility follows the provisions of the International Maritime Organization’s (IMO) Hong Kong Convention for the Safe and Environmentally Sound Recycling of Ships and, when applicable, the standards set forth by the European Union’s (EU) Ship Recycling Regulations.

• People

  Crew Training

  CLIA Members implement training programs that educate crewmembers on environmental requirements and responsible waste management practices. Advanced training in specific shipboard environmental management issues is provided for those directly involved in these areas. Additionally, those directly responsible for processing different waste streams are given specific instructions as to their duties and responsibilities, as well as the operation of the relevant equipment and waste management systems.

  Specific steps CLIA Members take to train crewmembers may include the following:

  • Comprehensive initial environmental training programs for new crewmembers with recurring and updated training on a periodic basis.
  • Announcements over the public address system, notices in ship newsletters, appropriate signage (required and voluntary), and informational posters (traditional and digital) in crew and passenger areas encouraging environmental awareness and protection.
  • Environmental information booklets in crew cabins and crew lounges.
  • Corporate and shipboard produced informational videos shown on cabin TV channels.
  • Presentations for crewmembers on company environmental programs and regulatory requirements.
  • Periodic environmental committee meetings, consisting of officers and crew from all departments to review methods of improving environmental performance, including enhanced and more effective environmental practices.
  • Any training required by different local or regional requirements based on a ship’s operating area.

  Passenger Awareness

  CLIA Members implement programs to enhance passenger environmental awareness that could include some of the following:

  • Announcements over the public address system.
  • Information and signage in passenger areas, encouraging environmental awareness and protection.
  • Informational videos shown on cabin TV channels.
  • Presentations for passengers on company environmental programs and regulatory requirements.
  • Government and local agency presentations on local and regional environmental programs.
