17 combination carriers in this register reported under EU MRV. The median vessel measures 36,861 gross tonnes, and build years run from 1998 to 2021.

Median EEOI for the type is 17.1 grams of CO₂ per tonne-mile. Half the fleet sits above that figure and half below, so a vessel's distance from the median is a fairer read of its efficiency than its absolute emissions, which mostly track how much work it did.

CO₂ by reporting year

Year Vessels CO₂ (t) Median EEOI
2018 6 53,668 19.4
2019 7 68,269 47.3
2020 9 69,325 26.0

2023 7 38,571 25.8
2024 8 28,145 24.4
2025 5 22,884 21.8

Each row counts the vessels in this group that filed a return for that year. The group changes as ships enter and leave the reporting obligation, so the totals describe the reported fleet, not a fixed set of hulls.
