FY2018 Energy & Emissions Performance

Icon LNG


As part of our commitment to reducing our air emissions and improving air quality in the environments we visit, we are pioneering the use of LNG, the world’s cleanest fossil fuel. In 2018 we:

  • Delivered the first cruise ship in the world (the AIDAnova) powered at sea and in port by Liquefied Natural Gas (LNG).
  • Began construction of additional LNG ships.
Icon operational efficiency


We continued our 12-year agreement with Wärtsilä to maintain the highest possible levels for cruise ship diesel engine safety and reliability. In 2018, we achieved a 0.6% fuel reduction.

IMO Icon

International maritime organization (IMO) and Climate Change

We remain active and interested in the worldwide strategies and frameworks being designed and developed to address climate change and air emissions. Specific to the maritime industry, the International Maritime Organization (IMO) is the specialized agency of the United Nations responsible for regulating shipping. We participate in IMO meetings and working groups through our trade association, the Cruise Lines International Association (CLIA). In 2018, the IMO established an initial greenhouse gas (GHG) emissions from ships reduction strategy in line with the COP21 (Paris Agreement). The strategy includes likely implementation of further phases of the Energy Efficiency Design Index (EEDI) for new ships, reducing international shipping’s average unit CO2 emissions by at least 40% by 2030 and by 70% by 2050 (relative to 2008), and reducing absolute international shipping GHG emissions by at least 50% by 2050 compared to 2008 and pursuing efforts to phase them out.

GHG Monitoring, Reporting and Verification

In 2018, we started to report our carbon emissions on all voyages to, from and between European Union ports. This program began on January 1, 2018 and requires any ship calling on or departing from a European Union or European Economic Area port to measure and report fuel consumption on the associated leg.

2018 European Union Our Oceans Conference – BALI

Carnival Corporation provided progress on our efforts to pioneer Liquefied Natural Gas in the cruise industry. This is part of Carnival’s approach to reduce greenhouse gas emissions. The Our Oceans conference seeks public commitments to actions that will reduce marine pollution, manage aquatic resources sustainably, mitigate climate change and establish marine sanctuaries.

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 were 99.5 percent of our total emissions, and the emissions generated from our ships’ fuel consumption represented the vast majority of our GHG emissions (97.4 percent). Our indirect GHG emissions represent only 0.5 percent of our total emissions, the bulk of which are attributed to electricity purchased to power our shore-based buildings. The graphic on page 70 depicts our energy use and related emissions.

Data aggregation and Analysis Platform – Neptune

In 2018, we continued the implementation of a state-of-the-art data aggregation and analysis platform called Neptune that enables real-time information transfer and sharing between our ships and shoreside teams supporting fleet operations. Our proprietary system significantly improves communication from ship to shore, providing new capabilities for enhancing the safe passage of ships at sea while improving operational efficiencies and supporting overall environmental, safety and security initiatives. The platform provides visual representations of ships routing, real-time navigational notifications, integrated weather data and traffic information and major equipment performance data, all which support operational efficiencies and minimize risk.

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. See Climate Change CDP Report for more information.

Our commitment

We believe in communicating transparently about climate change. We actively participate in the process of determining 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 more than 97% of our direct (Scope 1) carbon emissions 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. LNG is the world’s cleanest fossil fuel and in December 2018 we took delivery of our first ship to be powered by LNG – both in port and at sea. We have a ten additional new LNG ships on order. 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.

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.
