Maersk — container fleet

197 ships6.68 Mt CO₂ in 2025

The Maersk container fleet counts 197 ships reporting under the EU MRV regulation — the 3th largest reporting fleet — with a combined 6.68 Mt of verified CO₂ emissions in 2025. Every figure on this page comes from the yearly verified reports each ship files with EMSA.

Its total emissions went from 4.79 Mt of CO₂ in 2018 to 6.68 Mt in 2025, a trajectory that reflects both fleet size and operational efficiency choices such as slow steaming and vessel upgrades.

Maersk, the Danish group that defined modern container shipping, deliberately stopped chasing the size record to reinvent itself as an end-to-end logistics integrator. Its fleet strategy reflects that choice: rather than maximising capacity, Maersk became the industry's methanol pioneer — the Laura Maersk, delivered in 2023, was the world's first methanol-enabled container ship, and a series of large dual-fuel vessels has followed. Since February 2025 its ocean network runs in the Gemini Cooperation with Hapag-Lloyd, a hub-and-spoke design built around schedule reliability above 90%.

In the EU MRV data, the Maersk fleet is consistently among the largest reporters and its emissions trajectory is scrutinised as a proxy for the industry's energy transition: the company targets net-zero across its business by 2040, a decade ahead of IMO ambitions, which makes the year-on-year evolution of its verified CO₂ figures particularly telling.
