SIGMA against its type
Built in 2005, it is 2 years older than the median general cargo ship on this register, which was built in 2007 (2,852 vessels with a known build year). It is one of 216 general cargo ships here under the Liberia flag, 7.0% of the 3,081 on the register. The reported port of registry changed: Monrovia (2018–2021), then BRIDGETOWN (BB) (2022–2024).
Its 2,620 t of CO₂ for 2024 is 35% below the median of 4,046 t among the 1,395 general cargo ships on this register that reported for 2024. Per nautical mile it emitted 103.5 kg CO₂, 45% below the type median of 187.0 kg. It logged 2,476 hours at sea against a median of 2,074 hours for its type that year. 0.0% of its 2024 emissions were at berth; the median for general cargo ships was 3.9%. Across 7 years with reported emissions, the highest was 2024 (2,620 t) and the lowest 2021 (771 t). Its efficiency percentile within the type went from 32 in 2018 to 27 in 2024 (lower is more efficient).

Efficiency against its own type2024
Position 89 of 321 qualifying general cargo ships by EEOI, at the 27th percentile. The dashed line is the type median, 23.6; this vessel reported 16.4.
EEOI divides emissions by transport work, which for this vessel and year was 159,438,223 tonne-miles over 25,310 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2024 was 4.8% higher than in 2018, for EU/EEA voyages only.
From 2023 to 2024, emissions rose 35.5% while distance sailed rose 57.9%and CO₂ per nautical mile fell 14.2%.That points mainly to how much the vessel sailed, rather than the other.
