DIDIMON against its type
Built in 2005, it is 5 years older than the median chemical tanker on this register, which was built in 2010 (1,951 vessels with a known build year). At 25,124 gross tonnage it is larger than 58% 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 983 other vessels here, 330 of them chemical tankers. The returns for 2020–2025 all give Monrovia as port of registry.
Its 6,413 t of CO₂ for 2025 is 16% above the median of 5,531 t among the 1,484 chemical tankers on this register that reported for 2025. Per nautical mile it emitted 343.8 kg CO₂, 37% above the type median of 250.2 kg. It logged 2,475 hours at sea against a median of 2,106 hours for its type that year. 9.0% of its 2025 emissions were at berth; the median for chemical tankers was 6.6%. Across 6 years with reported emissions, the highest was 2024 (10,509 t) and the lowest 2023 (5,864 t). Its efficiency percentile within the type went from 91 in 2020 to 76 in 2025 (lower is more efficient). Of the 2 sister ships listed below with a 2025 return, 0 reported a lower CO₂ per nautical mile than this vessel.

Efficiency against its own type2025
Position 1,031 of 1,348 qualifying chemical tankers by EEOI, at the 76th percentile. The dashed line is the type median, 14.4; this vessel reported 24.1.
EEOI divides emissions by transport work, which for this vessel and year was 266,114,938 tonne-miles over 18,654 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2025 was 14.3% lower than in 2020, for EU/EEA voyages only.
From 2024 to 2025, emissions fell 39.0% while distance sailed fell 44.4%and CO₂ per nautical mile rose 9.8%.That points mainly to how much the vessel sailed, rather than the other.
