AURORA SPIRIT against its type
Built in 2019, it is 9 years newer than the median oil tanker on this register, which was built in 2010 (2,896 vessels with a known build year). At 90,000 gross tonnage it is larger than 86% of the other 2,841 oil tankers with a recorded tonnage. It is one of 180 oil tankers here under the Bahamas flag, 5.1% of the 3,548 on the register. The same builder is recorded for 563 other vessels here, 217 of them oil tankers. The reported port of registry changed: Stavanger (2020–2023), then Nassau (2024–2025).
Its 19,704 t of CO₂ for 2025 is 2.5 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 528.7 kg CO₂, 31% above the type median of 403.2 kg. It logged 6,415 hours at sea against a median of 2,030 hours for its type that year. 7.8% of its 2025 emissions were at berth; the median for oil tankers was 7.8%. Across 6 years with reported emissions, the highest was 2021 (23,603 t) and the lowest 2024 (17,346 t). Its efficiency percentile within the type went from 90 in 2020 to 85 in 2025 (lower is more efficient). Of the 8 sister ships listed below with a 2025 return, 7 reported a lower CO₂ per nautical mile than this vessel.

Efficiency against its own type2025
Position 1,226 of 1,448 qualifying oil tankers by EEOI, at the 85th percentile. The dashed line is the type median, 7.5; this vessel reported 14.1.
EEOI divides emissions by transport work, which for this vessel and year was 1,396,428,774 tonne-miles over 37,267 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2025 was 14.4% lower than in 2020, for EU/EEA voyages only.
From 2024 to 2025, emissions rose 13.6% while distance sailed rose 47.4%and CO₂ per nautical mile fell 22.9%.That points mainly to how much the vessel sailed, rather than the other.
