COSTANZA M 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 25,864 gross tonnage it is smaller than 87% of the other 2,841 oil tankers with a recorded tonnage. It is one of 43 oil tankers here under the Italy flag, 1.2% of the 3,548 on the register. The same builder is recorded for 21 other vessels here, 14 of them oil tankers. The returns for 2018–2025 all give Catania as port of registry.

Its 14,542 t of CO₂ for 2025 is 1.8 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 379.5 kg CO₂, close to the type median of 403.2 kg. It logged 3,629 hours at sea against a median of 2,030 hours for its type that year. 18.7% 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 (17,471 t) and the lowest 2022 (12,566 t). Its efficiency percentile within the type went from 98 in 2018 to 96 in 2025 (lower is more efficient). Of the 6 sister ships listed below with a 2025 return, 5 reported a lower CO₂ per nautical mile than this vessel.

Efficiency against its own type2025

Position 1,383 of 1,448 qualifying oil tankers by EEOI, at the 96th percentile. The dashed line is the type median, 7.5; this vessel reported 25.2.

EEOI divides emissions by transport work, which for this vessel and year was 577,745,729 tonne-miles over 38,322 nautical miles.

Reported CO₂ by year

Reported CO₂ in 2025 was 16.8% lower than in 2018, for EU/EEA voyages only.

From 2024 to 2025, emissions rose 11.5% while distance sailed rose 10.3%and CO₂ per nautical mile rose 1.1%.That points mainly to how much the vessel sailed, rather than the other.
