ECO CALIFORNIA: CO₂ emissions 2019–2025

ECO CALIFORNIA against its type

Built in 2019, it is 9 years newer than the median chemical tanker on this register, which was built in 2010 (1,951 vessels with a known build year). At 29,994 gross tonnage it is larger than 89% of the other 1,899 chemical tankers with a recorded tonnage. It is one of 474 chemical tankers here under the Marshall Islands flag, 20.2% of the 2,344 on the register. The same builder is recorded for 983 other vessels here, 330 of them chemical tankers. Its MRV returns name it ECO CALIFORNIA for 2019 and LARGO CALIFORNIA for 2020–2025. The returns for 2019–2025 all give Majuro as port of registry.

Its 2,062 t of CO₂ for 2025 is 63% below the median of 5,531 t among the 1,484 chemical tankers on this register that reported for 2025. Per nautical mile it emitted 242.9 kg CO₂, close to the type median of 250.2 kg. It logged 760 hours at sea against a median of 2,106 hours for its type that year. 7.4% of its 2025 emissions were at berth; the median for chemical tankers was 6.6%. Across 3 years with reported emissions, the highest was 2019 (6,597 t) and the lowest 2025 (2,062 t). Its efficiency percentile within the type went from 2 in 2019 to 29 in 2025 (lower is more efficient). Of the 5 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 390 of 1,348 qualifying chemical tankers by EEOI, at the 29th percentile. The dashed line is the type median, 14.4; this vessel reported 10.8.

EEOI divides emissions by transport work, which for this vessel and year was 191,115,848 tonne-miles over 8,491 nautical miles.

Reported CO₂ by year

Reported CO₂ in 2025 was 68.7% lower than in 2019, for EU/EEA voyages only. No return is recorded for 2023, 2024, so the series has gaps.

From 2020 to 2025, emissions fell 59.1% while distance sailed fell 64.2%and CO₂ per nautical mile rose 14.4%.That points mainly to how much the vessel sailed, rather than the other.
