CAROLUS MAGNUS 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 12,776 gross tonnage it is smaller than 65% 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 95 other vessels here, 6 of them chemical tankers. Its MRV returns name it CAROLUS MAGNUS for 2019–2022 and OLYMPIC FLAME for 2023–2025. The reported port of registry changed: Bridgetown (2019–2022), then MONROVIA (2023–2025).
Its 6,283 t of CO₂ for 2025 is 14% 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 262.7 kg CO₂, close to the type median of 250.2 kg. It logged 2,204 hours at sea against a median of 2,109 hours for its type that year. 6.9% 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 (8,970 t) and the lowest 2024 (4,042 t). Its efficiency percentile within the type went from 62 in 2019 to 66 in 2025 (lower is more efficient). Of the 4 sister ships listed below with a 2025 return, 3 reported a lower CO₂ per nautical mile than this vessel.

Efficiency against its own type2025
Position 897 of 1,348 qualifying chemical tankers by EEOI, at the 66th percentile. The dashed line is the type median, 14.4; this vessel reported 19.5.
EEOI divides emissions by transport work, which for this vessel and year was 322,847,379 tonne-miles over 23,915 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2025 was 22.0% lower than in 2019, for EU/EEA voyages only.
From 2024 to 2025, emissions rose 55.4% while distance sailed rose 51.3%and CO₂ per nautical mile rose 2.7%.That points mainly to how much the vessel sailed, rather than the other.
