MAERSK CYPRUS against its type
It is one of 72 oil tankers here under the Denmark flag, 2.0% of the 3,548 on the register. The returns for 2020–2025 all give Roskilde as port of registry.
Its 4,037 t of CO₂ for 2025 is 49% below the median of 7,922 t among the 1,704 oil tankers on this register that reported for 2025. Per nautical mile it emitted 209.4 kg CO₂, 48% below the type median of 403.2 kg. It logged 1,599 hours at sea against a median of 2,030 hours for its type that year. 5.2% of its 2025 emissions were at berth; the median for oil tankers was 7.8%. Across 5 years with reported emissions, the highest was 2021 (4,286 t) and the lowest 2020 (1,754 t). Its efficiency percentile within the type went from 32 in 2020 to 42 in 2025 (lower is more efficient). Of the 6 comparable vessels listed below with a 2025 return, 2 reported a lower CO₂ per nautical mile than this vessel.

Efficiency against its own type2025
Position 611 of 1,448 qualifying oil tankers by EEOI, at the 42nd percentile. The dashed line is the type median, 7.5; this vessel reported 6.9.
EEOI divides emissions by transport work, which for this vessel and year was 587,557,496 tonne-miles over 19,280 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2025 was 130.1% higher than in 2020, for EU/EEA voyages only. No return is recorded for 2022, so the series has gaps.
From 2024 to 2025, emissions rose 29.5% while distance sailed rose 58.0%and CO₂ per nautical mile fell 18.0%.That points mainly to how much the vessel sailed, rather than the other.
