DELTA MARIA against its type
It is one of 289 oil tankers here under the Malta flag, 8.1% of the 3,548 on the register. The reported port of registry changed: Piraeus (2018–2023), then Valletta (2024–2025).
Its 8,697 t of CO₂ for 2025 is close to the median of 7,922 t among the 1,704 oil tankers on this register that reported for 2025. Per nautical mile it emitted 367.7 kg CO₂, close to the type median of 403.2 kg. It logged 2,134 hours at sea against a median of 2,030 hours for its type that year. 4.9% of its 2025 emissions were at berth; the median for oil tankers was 7.8%. Across 8 years with reported emissions, the highest was 2018 (9,061 t) and the lowest 2019 (2,038 t). Its efficiency percentile within the type went from 20 in 2018 to 5 in 2025 (lower is more efficient). Of the 6 comparable vessels listed below with a 2025 return, 2 reported a lower CO₂ per nautical mile than this vessel.

Efficiency against its own type2025
Position 72 of 1,448 qualifying oil tankers by EEOI, at the 5th percentile. The dashed line is the type median, 7.5; this vessel reported 3.8.
EEOI divides emissions by transport work, which for this vessel and year was 2,276,761,780 tonne-miles over 23,651 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2025 was 4.0% lower than in 2018, for EU/EEA voyages only.
From 2024 to 2025, emissions rose 12.0% while distance sailed rose 58.5%and CO₂ per nautical mile fell 29.4%.That points mainly to how much the vessel sailed, rather than the other.
