STOLT BETULA against its type
Built in 2003, it is 7 years older than the median chemical tanker on this register, which was built in 2010 (1,951 vessels with a known build year). At 15,992 gross tonnage it is smaller than 61% 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 76 other vessels here, 58 of them chemical tankers. The returns for 2021–2025 all give Monrovia as port of registry.
Its 6,341 t of CO₂ for 2025 is 15% above the median of 5,533 t among the 1,483 chemical tankers on this register that reported for 2025. Per nautical mile it emitted 252.1 kg CO₂, close to the type median of 250.2 kg. It logged 2,075 hours at sea against a median of 2,109 hours for its type that year. 2.1% of its 2025 emissions were at berth; the median for chemical tankers was 6.6%. Across 7 years with reported emissions, the highest was 2023 (9,272 t) and the lowest 2019 (4,679 t). Its efficiency percentile within the type went from 75 in 2018 to 70 in 2025 (lower is more efficient). Of the 4 sister ships listed below with a 2025 return, 4 reported a lower CO₂ per nautical mile than this vessel.

Efficiency against its own type2025
Position 948 of 1,348 qualifying chemical tankers by EEOI, at the 70th percentile. The dashed line is the type median, 14.4; this vessel reported 20.7.
EEOI divides emissions by transport work, which for this vessel and year was 306,039,575 tonne-miles over 25,156 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2025 was 3.8% lower than in 2018, for EU/EEA voyages only. No return is recorded for 2020, so the series has gaps.
From 2024 to 2025, emissions rose 21.4% while distance sailed rose 37.1%and CO₂ per nautical mile fell 11.4%.That points mainly to how much the vessel sailed, rather than the other.
