DAN CISNE against its type
Built in 2011, it is 1 year newer than the median oil tanker on this register, which was built in 2010 (2,896 vessels with a known build year). At 36,303 gross tonnage it is smaller than 68% of the other 2,841 oil tankers with a recorded tonnage. It is one of 72 oil tankers here under the Denmark flag, 2.0% of the 3,548 on the register.
Its 17,580 t of CO₂ for 2025 is 2.2 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 589.4 kg CO₂, 46% above the type median of 403.2 kg. It logged 4,515 hours at sea against a median of 2,030 hours for its type that year. 12.0% of its 2025 emissions were at berth; the median for oil tankers was 7.8%. Across 3 years with reported emissions, the highest was 2025 (17,580 t) and the lowest 2023 (1,503 t). Its efficiency percentile within the type went from 93 in 2024 to 100 in 2025 (lower is more efficient). Of the 2 comparable vessels listed below with a 2025 return, 1 reported a lower CO₂ per nautical mile than this vessel.

Efficiency against its own type2025
Position 1,443 of 1,448 qualifying oil tankers by EEOI, at the 100th percentile. The dashed line is the type median, 7.5; this vessel reported 42.1.
EEOI divides emissions by transport work, which for this vessel and year was 417,566,508 tonne-miles over 29,828 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2025 was 1,069.7% higher than in 2023, for EU/EEA voyages only.
From 2024 to 2025, emissions rose 8.7% while distance sailed rose <0.1%and CO₂ per nautical mile rose 8.7%.That points mainly to how efficiently it sailed, rather than the other.
