ELONA against its type
It is one of 793 oil tankers here under the Marshall Islands flag, 22.4% of the 3,548 on the register. Its MRV returns name it ELONA for 2021 and SAFEEN ELONA for 2023–2025. The reported port of registry changed: Valletta (2021), then Majuro (2023–2025).
Its 20,796 t of CO₂ for 2025 is 2.6 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 560.2 kg CO₂, 39% above the type median of 403.2 kg. It logged 5,131 hours at sea against a median of 2,030 hours for its type that year. 15.0% of its 2025 emissions were at berth; the median for oil tankers was 7.8%. Across 4 years with reported emissions, the highest was 2025 (20,796 t) and the lowest 2023 (9,710 t). Its efficiency percentile within the type went from 47 in 2021 to 83 in 2025 (lower is more efficient). Of the 4 comparable vessels listed below with a 2025 return, 3 reported a lower CO₂ per nautical mile than this vessel.

Efficiency against its own type2025
Position 1,202 of 1,448 qualifying oil tankers by EEOI, at the 83rd percentile. The dashed line is the type median, 7.5; this vessel reported 13.2.
EEOI divides emissions by transport work, which for this vessel and year was 1,577,853,566 tonne-miles over 37,121 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2025 was 93.7% higher than in 2021, for EU/EEA voyages only. No return is recorded for 2022, so the series has gaps.
From 2024 to 2025, emissions rose 9.8% while distance sailed fell 10.1%and CO₂ per nautical mile rose 22.1%.That points mainly to how efficiently it sailed, rather than the other.
