HANS MAERSK against its type
Built in 2009, it is 1 year older than the median oil tanker on this register, which was built in 2010 (2,896 vessels with a known build year). At 25,709 gross tonnage it is smaller than 87% of the other 2,841 oil tankers with a recorded tonnage. 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 (2019–2024), then Svendborg (2025).
Its 12,047 t of CO₂ for 2025 is 1.5 times the median of 7,922 t among the 1,704 oil tankers on this register that reported for 2025. Per nautical mile it emitted 320.0 kg CO₂, 21% below the type median of 403.2 kg. It logged 3,335 hours at sea against a median of 2,030 hours for its type that year. 13.1% of its 2025 emissions were at berth; the median for oil tankers was 7.8%. Across 7 years with reported emissions, the highest was 2023 (12,989 t) and the lowest 2024 (2,078 t). Its efficiency percentile within the type went from 38 in 2019 to 91 in 2025 (lower is more efficient). Of the 5 comparable vessels listed below with a 2025 return, 4 reported a lower CO₂ per nautical mile than this vessel.

Efficiency against its own type2025
Position 1,323 of 1,448 qualifying oil tankers by EEOI, at the 91st percentile. The dashed line is the type median, 7.5; this vessel reported 19.7.
EEOI divides emissions by transport work, which for this vessel and year was 612,758,393 tonne-miles over 37,651 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2025 was 321.4% higher than in 2019, for EU/EEA voyages only.
From 2024 to 2025, emissions rose 479.6% and CO₂ per nautical mile fell 13.6%.Distance is missing for at least one of the two years, so activity and efficiency cannot be separated here.
