IRMA S against its type

Built in 2008, it is 1 year newer than the median general cargo ship on this register, which was built in 2007 (2,852 vessels with a known build year). At 20,236 gross tonnage it is larger than 79% of the other 2,665 general cargo ships with a recorded tonnage. It is one of 216 general cargo ships here under the Liberia flag, 7.0% of the 3,081 on the register. The same builder is recorded for 96 other vessels here, 38 of them general cargo ships. The returns for 2019–2025 all give Monrovia as port of registry.

Its 575 t of CO₂ for 2025 is 80% below the median of 2,820 t among the 2,469 general cargo ships on this register that reported for 2025. Per nautical mile it emitted 185.6 kg CO₂, 1.5 times the type median of 122.2 kg. It logged 267 hours at sea against a median of 3,044 hours for its type that year. 3.6% of its 2025 emissions were at berth; the median for general cargo ships was 4.3%. Across 5 years with reported emissions, the highest was 2020 (2,976 t) and the lowest 2025 (575 t). Its efficiency percentile within the type went from 15 in 2019 to 6 in 2025 (lower is more efficient). Of the 5 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 28 of 479 qualifying general cargo ships by EEOI, at the 6th percentile. The dashed line is the type median, 29.4; this vessel reported 11.3.

EEOI divides emissions by transport work, which for this vessel and year was 50,774,051 tonne-miles over 3,099 nautical miles.

Reported CO₂ by year

Reported CO₂ in 2025 was 79.4% lower than in 2019, for EU/EEA voyages only. No return is recorded for 2022, 2023, so the series has gaps.

From 2024 to 2025, emissions fell 75.9% while distance sailed fell 63.4%and CO₂ per nautical mile fell 34.2%.That points mainly to how much the vessel sailed, rather than the other.
