CHEMBULK KOBE against its type
Built in 2002, it is 8 years older than the median chemical tanker on this register, which was built in 2010 (1,951 vessels with a known build year). At 11,573 gross tonnage it is smaller than 77% of the other 1,899 chemical tankers with a recorded tonnage. It is one of 259 chemical tankers here under the Panama flag, 11.0% of the 2,344 on the register. The same builder is recorded for 17 other vessels here, 14 of them chemical tankers. Its MRV returns name it CHEMBULK KOBE for 2018–2019, MT CARP for 2023, GABY for 2024 and HELEN for 2025. The reported port of registry changed: MAJURO (2018–2019), then hai phong (2023–2024), then PANAMA (2025).
Its 2,388 t of CO₂ for 2025 is 57% 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 318.6 kg CO₂, 27% above the type median of 250.2 kg. It logged 800 hours at sea against a median of 2,106 hours for its type that year. 5.7% of its 2025 emissions were at berth; the median for chemical tankers was 6.6%. Across 5 years with reported emissions, the highest was 2024 (5,544 t) and the lowest 2023 (2,127 t). Its efficiency percentile within the type went from 70 in 2018 to 86 in 2025 (lower is more efficient). Of the 5 comparable vessels listed below with a 2025 return, 5 reported a lower CO₂ per nautical mile than this vessel.

Efficiency against its own type2025
Position 1,166 of 1,348 qualifying chemical tankers by EEOI, at the 86th percentile. The dashed line is the type median, 14.4; this vessel reported 32.6.
EEOI divides emissions by transport work, which for this vessel and year was 73,271,556 tonne-miles over 7,495 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2025 was 40.2% lower than in 2018, for EU/EEA voyages only. No return is recorded for 2020, 2021, 2022, so the series has gaps.
From 2024 to 2025, emissions fell 56.9% while distance sailed fell 64.8%and CO₂ per nautical mile rose 22.3%.That points mainly to how much the vessel sailed, rather than the other.
