CLEAROCEAN MARIA against its type
Built in 2014, it is 4 years newer than the median chemical tanker on this register, which was built in 2010 (1,951 vessels with a known build year). At 29,705 gross tonnage it is larger than 81% of the other 1,899 chemical tankers with a recorded tonnage. It is one of 402 chemical tankers here under the Liberia flag, 17.2% of the 2,344 on the register. The same builder is recorded for 180 other vessels here, 53 of them chemical tankers. Its MRV returns name it CLEAROCEAN MARIA for 2019–2023 and TRISTAR JISHA for 2025. The returns for 2019–2025 all give Monrovia as port of registry.
Its 8,905 t of CO₂ for 2025 is 1.6 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 248.6 kg CO₂, close to the type median of 250.2 kg. It logged 3,160 hours at sea against a median of 2,109 hours for its type that year. 6.7% of its 2025 emissions were at berth; the median for chemical tankers was 6.6%. Across 6 years with reported emissions, the highest was 2025 (8,905 t) and the lowest 2022 (2,850 t). Its efficiency percentile within the type went from 70 in 2019 to 20 in 2025 (lower is more efficient). Of the 3 sister ships listed below with a 2025 return, 0 reported a lower CO₂ per nautical mile than this vessel.

Efficiency against its own type2025
Position 272 of 1,348 qualifying chemical tankers by EEOI, at the 20th percentile. The dashed line is the type median, 14.4; this vessel reported 9.2.
EEOI divides emissions by transport work, which for this vessel and year was 967,900,000 tonne-miles over 35,814 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2025 was 57.3% higher than in 2019, for EU/EEA voyages only. No return is recorded for 2024, so the series has gaps.
From 2023 to 2025, emissions rose 73.6% while distance sailed rose 92.7%and CO₂ per nautical mile fell 9.9%.That points mainly to how much the vessel sailed, rather than the other.
