PASCHALIS DD against its type
It is one of 718 oil tankers here under the Liberia flag, 20.2% of the 3,548 on the register. Its MRV returns name it RS AURORA for 2018–2021 and PASCHALIS DD for 2022–2025. The reported port of registry changed: Majuro (2019), then Majuro, Marshall Islands (2020–2021), then Monrovia (2022–2025).
Its 11,227 t of CO₂ for 2025 is 42% above the median of 7,922 t among the 1,704 oil tankers on this register that reported for 2025. Per nautical mile it emitted 389.4 kg CO₂, close to the type median of 403.2 kg. It logged 2,627 hours at sea against a median of 2,030 hours for its type that year. 11.0% of its 2025 emissions were at berth; the median for oil tankers was 7.8%. Across 8 years with reported emissions, the highest was 2019 (11,887 t) and the lowest 2023 (2,768 t). Its efficiency percentile within the type went from 11 in 2018 to 17 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 247 of 1,448 qualifying oil tankers by EEOI, at the 17th percentile. The dashed line is the type median, 7.5; this vessel reported 4.9.
EEOI divides emissions by transport work, which for this vessel and year was 2,272,738,866 tonne-miles over 28,832 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2025 was 227.3% higher than in 2018, for EU/EEA voyages only.
From 2024 to 2025, emissions rose 83.7% while distance sailed rose 151.3%and CO₂ per nautical mile fell 26.9%.That points mainly to how much the vessel sailed, rather than the other.
