MAERSK CURACAO 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 7,715 t of CO₂ for 2025 is close to the median of 7,922 t among the 1,704 oil tankers on this register that reported for 2025. Per nautical mile it emitted 207.0 kg CO₂, 49% below the type median of 403.2 kg. It logged 3,163 hours at sea against a median of 2,030 hours for its type that year. 11.1% of its 2025 emissions were at berth; the median for oil tankers was 7.8%. Across 5 years with reported emissions, the highest was 2020 (10,765 t) and the lowest 2022 (2,428 t). Its efficiency percentile within the type went from 63 in 2019 to 35 in 2022 (lower is more efficient). Of the 5 comparable vessels listed below with a 2025 return, 1 reported a lower CO₂ per nautical mile than this vessel.

Reported CO₂ by year
Reported CO₂ in 2025 was 116.0% higher than in 2019, for EU/EEA voyages only. No return is recorded for 2023, 2024, so the series has gaps.
From 2022 to 2025, emissions rose 217.7% and CO₂ per nautical mile fell 17.1%.Distance is missing for at least one of the two years, so activity and efficiency cannot be separated here.
