TORM HELENE 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 2022–2025 all give Copenhagen as port of registry.
Its 4,437 t of CO₂ for 2025 is 44% 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 377.8 kg CO₂, close to the type median of 403.2 kg. It logged 1,068 hours at sea against a median of 2,030 hours for its type that year. 6.7% of its 2025 emissions were at berth; the median for oil tankers was 7.8%. Across 4 years with reported emissions, the highest was 2022 (8,709 t) and the lowest 2024 (256 t). Its efficiency percentile within the type went from 8 in 2022 to 5 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 77 of 1,448 qualifying oil tankers by EEOI, at the 5th percentile. The dashed line is the type median, 7.5; this vessel reported 3.9.
EEOI divides emissions by transport work, which for this vessel and year was 1,143,652,062 tonne-miles over 11,744 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2025 was 49.0% lower than in 2022, for EU/EEA voyages only.
From 2024 to 2025, emissions rose 1,630.9% and CO₂ per nautical mile rose 15.1%.Distance is missing for at least one of the two years, so activity and efficiency cannot be separated here.
