MARAN PYTHIA 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 79,890 gross tonnage it is larger than 70% of the other 2,841 oil tankers with a recorded tonnage. It is one of 215 oil tankers here under the Greece flag, 6.1% of the 3,548 on the register. The same builder is recorded for 761 other vessels here, 193 of them oil tankers. The returns for 2020–2025 all give Piraeus as port of registry.
Its 27,971 t of CO₂ for 2025 is 3.5 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 541.9 kg CO₂, 34% above the type median of 403.2 kg. It logged 6,102 hours at sea against a median of 2,030 hours for its type that year. 8.7% of its 2025 emissions were at berth; the median for oil tankers was 7.8%. Across 5 years with reported emissions, the highest was 2025 (27,971 t) and the lowest 2022 (7,428 t). Its efficiency percentile within the type went from 71 in 2020 to 64 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 934 of 1,448 qualifying oil tankers by EEOI, at the 64th percentile. The dashed line is the type median, 7.5; this vessel reported 8.8.
EEOI divides emissions by transport work, which for this vessel and year was 3,189,446,978 tonne-miles over 51,621 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2025 was 232.5% higher than in 2020, for EU/EEA voyages only. No return is recorded for 2021, so the series has gaps.
From 2024 to 2025, emissions rose 28.9% while distance sailed rose 20.7%and CO₂ per nautical mile rose 6.7%.That points mainly to how much the vessel sailed, rather than the other.
