DUZGIT ENDEAVOUR: CO₂ emissions 2021–2025

DUZGIT ENDEAVOUR against its type

Built in 2013, it is 3 years newer than the median chemical tanker on this register, which was built in 2010 (1,951 vessels with a known build year). At 10,276 gross tonnage it is smaller than 81% of the other 1,899 chemical tankers with a recorded tonnage. It is one of 29 chemical tankers here under the Türkiye flag, 1.2% of the 2,344 on the register. The returns for 2023–2025 all give ISTANBUL as port of registry.

Its 9,933 t of CO₂ for 2025 is 1.8 times the median of 5,533 t among the 1,483 chemical tankers on this register that reported for 2025. Per nautical mile it emitted 327.2 kg CO₂, 31% above the type median of 250.2 kg. It logged 3,053 hours at sea against a median of 2,109 hours for its type that year. 21.2% of its 2025 emissions were at berth; the median for chemical tankers was 6.6%. Across 4 years with reported emissions, the highest was 2025 (9,933 t) and the lowest 2021 (5,303 t). Its efficiency percentile within the type went from 82 in 2021 to 94 in 2025 (lower is more efficient). Of the 3 comparable vessels listed below with a 2025 return, 3 reported a lower CO₂ per nautical mile than this vessel.

Efficiency against its own type2025

Position 1,267 of 1,348 qualifying chemical tankers by EEOI, at the 94th percentile. The dashed line is the type median, 14.4; this vessel reported 41.7.

EEOI divides emissions by transport work, which for this vessel and year was 238,208,633 tonne-miles over 30,358 nautical miles.

Reported CO₂ by year

Reported CO₂ in 2025 was 87.3% higher than in 2021, for EU/EEA voyages only. No return is recorded for 2022, so the series has gaps.

From 2024 to 2025, emissions rose 55.0% while distance sailed rose 24.3%and CO₂ per nautical mile rose 24.7%.
