VALLESINA 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 60,185 gross tonnage it is larger than 52% of the other 2,841 oil tankers with a recorded tonnage. It is one of 289 oil tankers here under the Malta flag, 8.1% of the 3,548 on the register. The same builder is recorded for 204 other vessels here, 19 of them oil tankers. The returns for 2020–2025 all give Valletta as port of registry.

Its 21,503 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 496.1 kg CO₂, 23% above the type median of 403.2 kg. It logged 4,745 hours at sea against a median of 2,030 hours for its type that year. 15.7% 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 (25,945 t) and the lowest 2024 (7,984 t). Its efficiency percentile within the type went from 56 in 2020 to 80 in 2025 (lower is more efficient). Of the 3 sister ships listed below with a 2025 return, 1 reported a lower CO₂ per nautical mile than this vessel.

Efficiency against its own type2025

Position 1,153 of 1,448 qualifying oil tankers by EEOI, at the 80th percentile. The dashed line is the type median, 7.5; this vessel reported 11.5.

EEOI divides emissions by transport work, which for this vessel and year was 1,866,544,271 tonne-miles over 43,348 nautical miles.

Reported CO₂ by year

Reported CO₂ in 2025 was 17.1% lower than in 2018, for EU/EEA voyages only.

From 2024 to 2025, emissions rose 169.3% while distance sailed rose 216.9%and CO₂ per nautical mile fell 15.0%.That points mainly to how much the vessel sailed, rather than the other.
