MAERSK CAYMAN 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 reported port of registry changed: Singapore (2018–2019), then Skovshoved (2020–2024).
Its 1,377 t of CO₂ for 2024 is 83% below the median of 8,196 t among the 1,808 oil tankers on this register that reported for 2024. Per nautical mile it emitted 213.5 kg CO₂, 48% below the type median of 408.2 kg. It logged 564 hours at sea against a median of 2,020 hours for its type that year. 7.3% of its 2024 emissions were at berth; the median for oil tankers was 7.2%. Across 5 years with reported emissions, the highest was 2019 (6,182 t) and the lowest 2024 (1,377 t). Its efficiency percentile within the type went from 86 in 2018 to 24 in 2021 (lower is more efficient). Of the 2 comparable vessels listed below with a 2024 return, 0 reported a lower CO₂ per nautical mile than this vessel.

Reported CO₂ by year
Reported CO₂ in 2024 was 55.5% lower than in 2018, for EU/EEA voyages only. No return is recorded for 2022, 2023, so the series has gaps.
From 2021 to 2024, emissions fell 54.7% and CO₂ per nautical mile rose 2.7%.Distance is missing for at least one of the two years, so activity and efficiency cannot be separated here.
