Discover the world's largest shipping companies ranked by fleet energy efficiency (EEDI), updated for 2025. Our comprehensive analysis covers major global carriers and their shipping capacity.
his ranking identifies the world’s leading maritime carriers based on the energy efficiency of their fleets. . Updated for 2025, this ranking highlights carriers at the forefront of low-consumption, high-performance fleet operations.
The ranking is based on how efficiently a carrier’s fleet converts energy into transport work, evaluated through metrics like EEDI (Energy Efficiency Design Index), EEXI (Existing Ship Index), and fuel consumption per distance and tonnage.
We collect data from IMO emissions reports, classification societies, vessel registries, and public disclosures by shipping lines on energy performance.
Energy efficiency claims are verified through third-party environmental audits, technical specifications, and emissions monitoring frameworks.
Carriers are ranked based on fleet-wide averages for fuel consumption per nautical mile per TEU or DWT. We also assess vessel age, propulsion upgrades, and use of low-emission fuels.
Data is reviewed every quarter to account for newly delivered vessels, retrofitting programs, regulatory developments, and operator disclosures.
Energy efficiency reflects a carrier’s ability to reduce operational costs, improve sustainability, and comply with environmental regulations. Efficient fleets not only lower fuel consumption and GHG emissions, but also provide competitive advantages under IMO and EU carbon regulation frameworks.
Lower energy usage directly translates to reduced fuel costs, a key factor in liner competitiveness and rate management.
IMO 2023/2030 targets make energy efficiency a legal and operational priority, with ratings like CII impacting operational freedom and future fleet planning.
ustainable fleet operations enhance corporate reputation and attract ESG-conscious clients, investors, and cargo owner.
This list ranks carriers by average fleet energy efficiency across their operated vessels in 2025. High performers demonstrate investment in clean technologies, efficient operations, and long-term sustainability strategies.

Carriers globally ordered 2,200+ next-generation vessels in 2023-2024, most equipped with dual-fuel engines or optimized hull designs.
Average energy consumption per TEU-km decreased by 6,2% across top-performing fleets between 2021 and 2024.
IMO regulations now require all ships to meet minimum EEXI and CII thresholds, directly linking energy performance to legal operations and charter eligibility.
Japanese and Korean carriers lead in hybrid engine adoption and smart ship energy management systems, combining fuel savings with emissions transparency.
European companies, led by Maersk and CMA CGM, are pioneering the use of methanol-fueled vessels, LNG retrofits, and onboard energy optimization technologies:
