DUMBLEDORE against its type
Built in 2007, it is 3 years older than the median chemical tanker on this register, which was built in 2010 (1,951 vessels with a known build year). At 31,433 gross tonnage it is larger than 98% of the other 1,899 chemical tankers with a recorded tonnage. It is one of 30 chemical tankers here under the Bahamas flag, 1.3% of the 2,344 on the register. The same builder is recorded for 307 other vessels here, 98 of them chemical tankers. Its MRV returns name it STAR FALCON for 2019–2020 and DUMBLEDORE for 2022–2025. The reported port of registry changed: Majuro (2019–2020), then nassau (2022–2025).
Its 2,632 t of CO₂ for 2025 is 52% below the median of 5,533 t among the 1,483 chemical tankers on this register that reported for 2025. Per nautical mile it emitted 285.9 kg CO₂, 14% above the type median of 250.2 kg. It logged 906 hours at sea against a median of 2,109 hours for its type that year. 9.5% of its 2025 emissions were at berth; the median for chemical tankers was 6.6%. Across 4 years with reported emissions, the highest was 2022 (4,948 t) and the lowest 2020 (1,154 t). Its efficiency percentile within the type went from 61 in 2019 to 12 in 2025 (lower is more efficient). Of the 5 sister ships listed below with a 2025 return, 5 reported a lower CO₂ per nautical mile than this vessel.

Efficiency against its own type2025
Position 169 of 1,348 qualifying chemical tankers by EEOI, at the 12th percentile. The dashed line is the type median, 14.4; this vessel reported 8.3.
EEOI divides emissions by transport work, which for this vessel and year was 317,439,083 tonne-miles over 9,203 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2025 was 0.8% lower than in 2019, for EU/EEA voyages only. No return is recorded for 2021, 2023, 2024, so the series has gaps.
From 2022 to 2025, emissions fell 46.8% and CO₂ per nautical mile fell 25.8%.Distance is missing for at least one of the two years, so activity and efficiency cannot be separated here.
