GUANABARA against its type
Built in 2007, it is 3 years older than the median oil tanker on this register, which was built in 2010 (2,896 vessels with a known build year). At 57,462 gross tonnage it is smaller than 53% of the other 2,841 oil tankers with a recorded tonnage. It is one of 793 oil tankers here under the Marshall Islands flag, 22.4% of the 3,548 on the register. The same builder is recorded for 360 other vessels here, 27 of them oil tankers. Its MRV returns name it GUANABARA for 2019–2021 and SOUSTA for 2022–2024. The reported port of registry changed: SINGAPORE (2019–2021), then Majuro (2022–2024).
Its 9,456 t of CO₂ for 2024 is 15% above the median of 8,196 t among the 1,808 oil tankers on this register that reported for 2024. Per nautical mile it emitted 467.9 kg CO₂, 15% above the type median of 408.2 kg. It logged 1,966 hours at sea against a median of 2,020 hours for its type that year. 13.4% of its 2024 emissions were at berth; the median for oil tankers was 7.2%. Across 5 years with reported emissions, the highest was 2021 (21,647 t) and the lowest 2022 (8,101 t). Its efficiency percentile within the type went from 74 in 2019 to 29 in 2024 (lower is more efficient). Of the 3 sister ships listed below with a 2024 return, 2 reported a lower CO₂ per nautical mile than this vessel.

Efficiency against its own type2024
Position 455 of 1,566 qualifying oil tankers by EEOI, at the 29th percentile. The dashed line is the type median, 7.6; this vessel reported 5.9.
EEOI divides emissions by transport work, which for this vessel and year was 1,600,020,305 tonne-miles over 20,211 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2024 was 18.1% lower than in 2019, for EU/EEA voyages only. No return is recorded for 2023, so the series has gaps.
From 2022 to 2024, emissions rose 16.7% while distance sailed rose 31.1%and CO₂ per nautical mile fell 10.9%.That points mainly to how much the vessel sailed, rather than the other.
