ADEBOLA ADELINE 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 83,545 gross tonnage it is larger than 81% of the other 2,841 oil tankers with a recorded tonnage. It is one of 718 oil tankers here under the Liberia flag, 20.2% of the 3,548 on the register. The same builder is recorded for 34 other vessels here, 20 of them oil tankers. Its MRV returns name it ASPEN SPIRIT for 2018–2024 and ADEBOLA ADELINE for 2025. The reported port of registry changed: Nassau (2018–2024), then Monrovia (2025).
Its 16,777 t of CO₂ for 2025 is 2.1 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 512.9 kg CO₂, 27% above the type median of 403.2 kg. It logged 3,540 hours at sea against a median of 2,030 hours for its type that year. 6.2% of its 2025 emissions were at berth; the median for oil tankers was 7.8%. Across 7 years with reported emissions, the highest was 2025 (16,777 t) and the lowest 2019 (5,736 t). Its efficiency percentile within the type went from 41 in 2018 to 44 in 2025 (lower is more efficient). Of the 3 sister ships listed below with a 2025 return, 3 reported a lower CO₂ per nautical mile than this vessel.

Efficiency against its own type2025
Position 633 of 1,448 qualifying oil tankers by EEOI, at the 44th percentile. The dashed line is the type median, 7.5; this vessel reported 7.0.
EEOI divides emissions by transport work, which for this vessel and year was 2,403,587,393 tonne-miles over 32,710 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2025 was 177.6% higher than in 2018, for EU/EEA voyages only. No return is recorded for 2020, so the series has gaps.
From 2024 to 2025, emissions rose 11.3% while distance sailed rose 0.9%and CO₂ per nautical mile rose 10.3%.That points mainly to how efficiently it sailed, rather than the other.
