We Are Focused on


Our pursuit of net zero emissions is multi-faceted and involves taking proactive steps to continuously improve the energy efficiency of our operations, leveraging the tools and technologies available today, while monitoring activities and investments in the development of low-carbon fuels at scale.

Our Decarbonization Strategy Has 4 Components:

Fleet Optimization

Delivering larger, more efficient ships as part of our ongoing newbuild program, some of which may replace existing ships in our fleet

Energy Efficiency

Continuing to improve our existing fleet’s energy efficiency through investment in projects such as service power packages, air lubrication systems, and expanding shore power capabilities to leverage renewable energy sources while in port

Itinerary Efficiency

Designing more energy-efficient itineraries, focusing on operational execution and investing in port and destination projects in strategy locations

New Technologies and Alternative Fuels

Investing in a first-of-its-kind lithium-ion battery storage system and assessing carbon capture and storage. We also support the adaptation of alternative fuels including biofuels such as methanol, which we are assessing as a future low greenhouse gas emission fuel option for our ship

Our Decarbonization Governance and Strategy

Our entire management team, including our Boards of Directors, is committed to our decarbonization governance and strategy. Our Boards and Chief Climate Officer review and approve our decarbonization initiatives and investments.

Since 2015, we have made over $500M in capital investments to upgrade our existing ships with energy efficient equipment and technologies. Our current investments focus on known technologies that will improve energy efficiency, such as the Service Power Package upgrades, air lubrication systems, and waste heat recovery projects. These investments are designed to directly reduce our footprint versus investing in carbon offset or inset programs, and they are paying off.

During 2023, our Boards of Directors and Chief Climate Officer approved the acceleration of our 2030 greenhouse gas emissions intensity reduction goal by four years to 2026.

As part of our governance, we also focus on being prepared for new regulations. This includes the latest developments on greenhouse gas regulations at the International Maritime Organization and the European Union.

The European Union’s Emissions Trading Scheme applies to our emissions beginning January 1, 2024.

The International Maritime Organization’s (IMO) Greenhouse Gas Revised Strategy, which was adopted in July 2023, includes the requirement to uptake zero or near zero emission technologies and fuels and has absolute emission reduction targets, including a net zero target by or around 2050.

The revised strategy also considers “well to wake” (entire fuel life cycle) instead of only “tank to wake” (combustion) emissions.

Looking Ahead


Updated our greenhouse gas emissions baseline from 2008 to 2019.

Completed Scope 3 greenhouse gas emissions baseline inventory.


Our accelerated commitment to achieve 20% greenhouse gas intensity reduction relative to our 2019 baseline measured in kilograms of CO2e per ALBD


Aspire to achieve net zero emissions from ship operations

Alternative Fuels

To provide a path to net zero emissions, alternative low GHG emission fuels will be necessary for the maritime industry; however, there are significant supply challenges that must be resolved before viability is reached.
