HAFNIA EXCELLENCE against its type
It is one of 237 oil tankers here under the Singapore flag, 6.7% of the 3,548 on the register. Its MRV returns name it STI EXCELLENCE for 2018–2021 and HAFNIA EXCELLENCE for 2022–2025. The reported port of registry changed: Majuro (2018–2021), then Singapore (2022–2025).
Its 3,048 t of CO₂ for 2025 is 62% 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 293.1 kg CO₂, 27% below the type median of 403.2 kg. It logged 920 hours at sea against a median of 2,030 hours for its type that year. 5.8% of its 2025 emissions were at berth; the median for oil tankers was 7.8%. Across 6 years with reported emissions, the highest was 2018 (3,320 t) and the lowest 2024 (2,046 t). Its efficiency percentile within the type went from 14 in 2018 to 30 in 2025 (lower is more efficient). Of the 8 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 440 of 1,448 qualifying oil tankers by EEOI, at the 30th percentile. The dashed line is the type median, 7.5; this vessel reported 6.0.
EEOI divides emissions by transport work, which for this vessel and year was 509,617,057 tonne-miles over 10,396 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2025 was 8.2% lower than in 2018, for EU/EEA voyages only. No return is recorded for 2019, 2020, so the series has gaps.
From 2024 to 2025, emissions rose 49.0% while distance sailed rose 106.6%and CO₂ per nautical mile fell 27.9%.That points mainly to how much the vessel sailed, rather than the other.
