MONTE SERANTES 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 82,839 gross tonnage it is larger than 79% of the other 2,841 oil tankers with a recorded tonnage. It is one of 56 oil tankers here under the Portugal flag, 1.6% of the 3,548 on the register. The same builder is recorded for 4 other vessels here, 2 of them oil tankers. The returns for 2024–2025 all give Madeira as port of registry.
Its 21,150 t of CO₂ for 2025 is 2.7 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 470.0 kg CO₂, 17% above the type median of 403.2 kg. It logged 4,211 hours at sea against a median of 2,030 hours for its type that year. 10.7% 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 (25,103 t) and the lowest 2019 (4,155 t). Its efficiency percentile within the type went from 1 in 2019 to 26 in 2025 (lower is more efficient). Of the 8 comparable vessels listed below with a 2025 return, 5 reported a lower CO₂ per nautical mile than this vessel.

Efficiency against its own type2025
Position 384 of 1,448 qualifying oil tankers by EEOI, at the 26th percentile. The dashed line is the type median, 7.5; this vessel reported 5.7.
EEOI divides emissions by transport work, which for this vessel and year was 3,704,050,788 tonne-miles over 44,997 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2025 was 409.0% higher than in 2019, for EU/EEA voyages only. No return is recorded for 2023, so the series has gaps.
From 2024 to 2025, emissions rose 5.9% while distance sailed rose 2.1%and CO₂ per nautical mile rose 3.7%.That points mainly to how efficiently it sailed, rather than the other.
