IRIS VICTORIA against its type
Built in 2010, it is the same age as the median oil tanker on this register (build year 2010, 2,896 vessels with a known build year). At 40,975 gross tonnage it is smaller than 66% of the other 2,841 oil tankers with a recorded tonnage. It is one of 180 oil tankers here under the Bahamas flag, 5.1% of the 3,548 on the register. The same builder is recorded for 69 other vessels here, 17 of them oil tankers. Its MRV returns name it IRIS VICTORIA for 2018–2019 and PORTOFINO for 2023–2025. The reported port of registry changed: Majuro (2019), then nassau (2023–2025).
Its 2,673 t of CO₂ for 2025 is 66% below the median of 7,922 t among the 1,704 oil tankers on this register that reported for 2025. Per nautical mile it emitted 347.3 kg CO₂, 14% below the type median of 403.2 kg. It logged 686 hours at sea against a median of 2,030 hours for its type that year. 3.7% of its 2025 emissions were at berth; the median for oil tankers was 7.8%. Across 4 years with reported emissions, the highest was 2018 (4,370 t) and the lowest 2025 (2,673 t). Its efficiency percentile within the type went from 38 in 2018 to 27 in 2025 (lower is more efficient). The one sister ship listed below with a 2025 return reported a lower CO₂ per nautical mile.

Efficiency against its own type2025
Position 395 of 1,448 qualifying oil tankers by EEOI, at the 27th percentile. The dashed line is the type median, 7.5; this vessel reported 5.8.
EEOI divides emissions by transport work, which for this vessel and year was 464,022,569 tonne-miles over 7,695 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2025 was 38.8% lower than in 2018, for EU/EEA voyages only. No return is recorded for 2020, 2021, 2022, 2024, so the series has gaps.
From 2023 to 2025, emissions fell 21.0% while distance sailed fell 17.4%and CO₂ per nautical mile fell 4.4%.That points mainly to how much the vessel sailed, rather than the other.
