Carnival’s Pathway to Decarbonization icon

Carnival’s Pathway to Decarbonization

Addressing climate change is one of our top priorities and we are committed to continue to lead the path within the cruise industry. Our entire management team, including our Board of Directors, is committed to addressing climate change. Our path to decarbonization involves multimillion-dollar investments and a multi-faceted strategy. Key components of this strategy include adopting international frameworks and working with industry regulatory bodies to: address upcoming regulatory requirements and conditions, maximize efficiency opportunities/gains, implement low carbon fuels, invest in carbon-efficient technologies, support and accelerate industry-specific research & development projects, establish internal goals supporting the path as well as partner with other companies, NGOs, and relevant stakeholders. In the coming years, we are likely to see an array of emerging technological innovations as currently there is not a single (nor a combination of technologies) that can move the maritime industry straight into a decarbonization path. As we navigate this journey, we are committed to evaluate options, work with various stakeholders, and adjust our path as needed. Please see this page for further details.

Alternative Fuels: Liquefied Natural Gas (LNG) icon

Alternative Fuels: Liquefied Natural Gas (LNG)

The introduction of LNG to power cruise ships is a major development that supports our environmental goals and significantly improves overall air emissions. In 2019, Carnival Corporation & plc continued to pioneer the use of LNG in the cruise industry by introducing Carnival Corporation & plc’s second LNG-powered ship, Costa Smeralda. She follows AIDAnova, delivered in 2018 as the world’s first cruise vessel to be powered by LNG. Carnival Corporation & plc has an additional nine next-generation LNG-powered cruise ships on order using the company’s innovative environmental design with expected delivery dates for these new ships between 2020 and 2025.

Fuel Cells icon

Fuel Cells

In 2019, we announced a joint venture between Carnival Corporation & plc’s AIDA brand, the Meyer Werft shipyard, Freudenberg Sealing Technologies and other partners funded by the German Federal Ministry of Transport and Digital Infrastructure. The objective of the joint venture is to find practical solutions for climate-neutral mobility across all of shipping. The groundbreaking “Pa-X-ell2” project specifically aims to develop a decentralized energy network and a hybrid energy system by using a new generation of fuel cells in oceangoing passenger vessels. As early as 2021, AIDA Cruises will be the world’s first cruise company to test the use of fuel cells on a large passenger ship. The fuel cells are powered by hydrogen derived from methanol and will enable cruise ships to cut carbon emissions, reduce noise, and lower vibrations.

Batteries icon

Batteries

In 2019, we signed an agreement with Corvus Energy, the world’s leading marine battery supplier, to begin production and installation of a first-of-its-kind lithium- ion battery storage system on board a cruise ship. The battery system is scheduled to be installed in 2020. The technology is currently set to become the world’s largest battery storage system ever installed on a passenger ship.

Cold Iron/Shore Power Plug-In Capabilities icon

Cold Iron/Shore Power Plug-In Capabilities

Cruise ships equipped with Cold Ironing or Shore Power plug-in capabilities can plug in to specific port connections facilities allowing the ship to receive electricity from the electrical grid in the port instead of using the ship’s engines and fuel to generate power. Electricity generated by renewable sources such as water (hydro), solar, wind, and geothermal have a minimal climate change and air emission impact compared with non-renewable sources such as fossil fuels. In 2019, there were only twelve ports worldwide able to provide Shore Power connections to our fleet based on our port-itinerary and our ships connected in all of them. Within the Carnival fleet, 47 ships are equipped with the ability to utilize Cold Ironing/Shore Power connections.

2020 Global Sulphur Cap - IMO 2020 icon

2020 Global Sulphur Cap - IMO 2020

As of the 1st of January 2020, the global limit for sulphur in fuel oil used on board all ships operating outside designated Emission Control Areas (ECAs) was reduced from 3.50% to 0.50%. This new marine emission requirement is also referred to as IMO 2020. In preparation for the new global requirement, each Carnival Corporation ship developed a ship- specific implementation plan to address using new fuels, fuel oil system modifications, and fuel tank configuration changes. In addition, fuel procurement, sampling requirements, and fuel oil bunkering procedures were revised. We have also equipped our fleet with Advanced Air Quality Systems (also known as scrubbers) which remove 99% of sulphur in fuel.

Advanced Air Quality Systems - Fleet Update icon

Advanced Air Quality Systems - Fleet Update

Advanced air quality systems (AAQS), generically known as exhaust gas cleaning systems or scrubbers, remove sulphur compounds and particulate matter from our ships’ engine exhaust at any operating state – at sea, during maneuvering, and in port. As of the end of FY2019, 77% of our fleet has been equipped with AAQS and we plan to deploy additional systems across our global fleet. In 2019, we also released the Carnival/DNVGL 2018 Wash Water Assessment, a four-year scientific wash water study that collected 281 wash water samples from 53 Carnival ships and completed lab analyses on each sample for 54 different parameters. The AAQS wash water samples were well below the limits set by several major national and international land-based water quality standards up to and including the World Health Organization (WHO) standards for drinking water. We also developed a specific website to provide comprehensive AAQS details for all interested stakeholders.

Partnerships: Jean-Michel Cousteau - Ocean Futures Society icon

Partnerships: Jean-Michel Cousteau - Ocean Futures Society

Carnival Corporation & plc partnered with renowned ocean explorer and life-long environmental advocate Jean-Michel Cousteau and his Ocean Futures Society, a nonprofit marine conservation and education organization that serves as a “Voice for the Ocean” on the importance of effective environmental and sustainability policy. Cousteau is providing valuable external expertise on environmental initiatives as we continue our commitment to sustainability and our oceans.

Partnership: Getting to Zero Coalition icon

Partnership: Getting to Zero Coalition

The Getting to Zero Coalition is an alliance of organizations across the maritime, energy, infrastructure, and finance sectors committed to accelerating the decarbonization of the international shipping industry. Carnival Corporation & plc is the first cruise company to join this global alliance.

The coalition’s goal aligns with the International Maritime Organization’s (IMO) strategy to reduce greenhouse gas emissions from shipping by at least 50% by 2050 as compared to 2008 emissions. To meet the target, the Getting to Zero Coalition aspires to having technically feasible, commercially viable zero-emission deep-sea vessels (ZEVs) entering the global shipping fleet as early as 2030. The alliance’s goal also includes scalable infrastructure for zero- carbon energy sources, including production, distribution, storage, and bunkering.

Supported by key governments and intergovernmental organizations, the coalition represents a leading group of over 80 companies, including global stakeholders from a variety of shipping-related industries such as fuel suppliers, engine manufacturers, marine classification societies, shipping companies, major ports, and more.

CDP Carbon Disclosure icon

CDP Carbon Disclosure

We have reported our carbon emissions in the CDP (formerly known as the Carbon Disclosure Project) since 2007. In 2019, we submitted our disclosure and received a management score level (B-) for climate change.

Voluntary Emissions Reduction Agreements icon

Voluntary Emissions Reduction Agreements

Carnival’s Costa Cruises signed two voluntary emission reduction agreements in 2019, The Marseille and La Spezia Blue Flag Agreements.

Direct & Indirect Emissions icon

Direct & Indirect Emissions

We quantify, report, and verify our greenhouse gas (GHG) emissions, including our direct (Scope 1) and indirect (Scope 2) emissions. Our direct GHG emissions represent 99.6 percent of our total emissions and the emissions generated from our ships’ fuel consumption represented the vast majority of our GHG footprint (97.3 percent). Our indirect GHG emissions represent only 0.4 percent of our total emissions, the majority of which are attributed to electricity purchased to power our shore-based buildings.

HESS Event Reporting System icon

HESS Event Reporting System

In 2019, we completed the fleetwide rollout of a new health, environment, safety and security (HESS) event reporting system. This platform has allowed us to standardize our HESS event reporting and analysis capabilities across the entire fleet.

Scope 3 Emissions icon

Scope 3 Emissions

We have reported our Scope 3 emissions in the CDP (formerly known as the Carbon Disclosure Project) since 2009. Scope 3 emissions are derived from the energy used in other upstream and downstream indirect emissions like business travel, passenger transportation to and from our ships, fuel transport, waste disposal, and deliveries of supplies.

Our

Commitment

We believe in communicating transparently about our company and industry’s role in addressing climate change. We have publicly disclosed our carbon footprint since 2006 and are taking specific and proactive steps to reduce this footprint. Energy is vital to our business so that guests can enjoy our facilities and amenities on our ships while at sea and in port.

Fuel is the primary source of energy consumed for the propulsion of our fleet and our onboard hotel power requirements. Our shipboard fuel consumption contributes to 97.3% of our direct carbon emissions (Scope 1) and is therefore the most significant contributor to our carbon footprint and the number one focus of our carbon reduction efforts.

Our

Strategy

We have implemented multiple energy-savings initiatives to manage our emissions footprint. See Energy-Saving Initiatives in the Appendix for further details.

We have established a Corporate Energy Conservation group charged with reducing our overall energy consumption. The goal of this group is to identify both immediate and long term opportunities for saving fuel.

We are actively involved in new shipbuilding research and development for emission abatement technologies and new equipment to further improve energy efficiency. We are pioneering the use of liquefied natural gas (LNG) for the cruise industry. In 2018, we made history with the launch of AIDAnova, the first cruise ship in the world powered by LNG both at sea and in port. In 2019, we launched the second LNG cruise ship in our fleet, and in the world, Costa Smeralda. We are leading the cruise industry’s use of LNG to power cruise ships; we have nine additional sister vessels due for delivery between 2020 and 2025 for our Costa Cruises, AIDA Cruises, P&O Cruises UK, Carnival Cruise Line and Princess Cruises. We also continue to work on practical, feasible energy reduction and conservation initiatives to help us reach our targets. Reducing fuel use and driving energy efficiency takes multi-million dollar investments and a multi-pronged, multi-year strategy.

These include abatement technologies and equipment to further reduce engine emissions such as:

  • Advanced Air Quality Systems (AAQS) that use proprietary technology to remove sulfur oxides and particulate matter from engine exhaust.
  • Cold Ironing capabilities that allow us to plug into a port’s electrical grid while in port if the shoreside infrastructure is available.
  • Air Lubrication Systems using air bubbles to reduce friction between ship’s hull and the water.
  • A performance-based maintenance and engine efficiency monitoring agreement with Wärtsilä, our largest main engine manufacturer.

We quantify, monitor, report, and verify our GHG emissions. We developed a GHG Inventory Management Plan (GHG IMP) in 2010 in accordance with the requirements of ISO 14064-1:2006 and The Greenhouse Gas Protocol. Our GHG emissions are independently verified by a third-party. Lloyd’s Register Quality Assurance Inc. (LRQA) certified our scope 1 and scope 2 GHG emissions inventory. For more information on our third-party verification visit our Assurance Statement in the Appendix.

We continue to train and certify employees responsible for main engine, refrigeration and air-conditioning plants. We use recovery units certified to meet refrigerant recycling and recovery requirements and we implement programs to reduce Ozone Depleting Substance (ODS) releases.
