DELTA TOLMI 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 81,360 gross tonnage it is larger than 74% of the other 2,841 oil tankers with a recorded tonnage. It is one of 718 oil tankers here under the Liberia flag, 20.2% of the 3,548 on the register. The same builder is recorded for 461 other vessels here, 179 of them oil tankers. The reported port of registry changed: Piraeus (2018–2019), then Monrovia (2020–2025).
Its 10,465 t of CO₂ for 2025 is 32% 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 479.2 kg CO₂, 19% above the type median of 403.2 kg. It logged 2,104 hours at sea against a median of 2,030 hours for its type that year. 10.5% of its 2025 emissions were at berth; the median for oil tankers was 7.8%. Across 8 years with reported emissions, the highest was 2020 (20,358 t) and the lowest 2023 (5,522 t). Its efficiency percentile within the type went from 11 in 2018 to 48 in 2025 (lower is more efficient). Of the 2 sister ships listed below with a 2025 return, 2 reported a lower CO₂ per nautical mile than this vessel.

Efficiency against its own type2025
Position 695 of 1,448 qualifying oil tankers by EEOI, at the 48th percentile. The dashed line is the type median, 7.5; this vessel reported 7.3.
EEOI divides emissions by transport work, which for this vessel and year was 1,433,506,849 tonne-miles over 21,836 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2025 was 46.6% higher than in 2018, for EU/EEA voyages only.
From 2024 to 2025, emissions fell 33.1% while distance sailed fell 45.2%and CO₂ per nautical mile rose 22.1%.That points mainly to how much the vessel sailed, rather than the other.
