MARITIME ROSEMARY 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 29,211 gross tonnage it is larger than 68% of the other 1,899 chemical tankers with a recorded tonnage. It is one of 65 chemical tankers here under the Hong Kong flag, 2.8% of the 2,344 on the register. The same builder is recorded for 146 other vessels here, 7 of them chemical tankers. The returns for 2020–2023 all give Hong Kong as port of registry.
Its 5,374 t of CO₂ for 2023 is close to the median of 5,393 t among the 1,411 chemical tankers on this register that reported for 2023. Per nautical mile it emitted 292.4 kg CO₂, 13% above the type median of 258.0 kg. It logged 1,604 hours at sea against a median of 1,919 hours for its type that year. 4.0% of its 2023 emissions were at berth; the median for chemical tankers was 8.2%. Across 3 years with reported emissions, the highest was 2020 (6,403 t) and the lowest 2021 (3,098 t). Its efficiency percentile within the type went from 22 in 2020 to 45 in 2023 (lower is more efficient). The one sister ship listed below with a 2023 return reported a lower CO₂ per nautical mile.

Efficiency against its own type2023
Position 551 of 1,230 qualifying chemical tankers by EEOI, at the 45th percentile. The dashed line is the type median, 15.6; this vessel reported 14.4.
EEOI divides emissions by transport work, which for this vessel and year was 371,899,654 tonne-miles over 18,376 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2023 was 16.1% lower than in 2020, for EU/EEA voyages only. No return is recorded for 2022, so the series has gaps.
From 2021 to 2023, emissions rose 73.5% while distance sailed rose 69.0%and CO₂ per nautical mile rose 2.7%.That points mainly to how much the vessel sailed, rather than the other.
