HULDA MAERSK against its type
Built in 2010, it is the same age as the median oil tanker on this register (build year 2010, 2,896 vessels with a known build year). At 25,710 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 returns for 2020–2025 all give Svendborg as port of registry.
Its 4,225 t of CO₂ for 2025 is 47% 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 297.8 kg CO₂, 26% below the type median of 403.2 kg. It logged 1,236 hours at sea against a median of 2,030 hours for its type that year. 12.1% 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 (11,353 t) and the lowest 2020 (3,277 t). Its efficiency percentile within the type went from 10 in 2020 to 96 in 2024 (lower is more efficient). Of the 8 comparable vessels listed below with a 2025 return, 4 reported a lower CO₂ per nautical mile than this vessel.

Reported CO₂ by year
Reported CO₂ in 2025 was 1.1% higher than in 2019, for EU/EEA voyages only.
From 2024 to 2025, emissions fell 61.6% and CO₂ per nautical mile fell 11.1%.Distance is missing for at least one of the two years, so activity and efficiency cannot be separated here.
