LEOPOLD STAFF: CO₂ emissions 2018–2025

LEOPOLD STAFF against its type

Built in 2004, it is 3 years older than the median general cargo ship on this register, which was built in 2007 (2,852 vessels with a known build year). At 24,167 gross tonnage it is larger than 91% 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 reported port of registry changed: Valletta (2018–2022), then Monrovia (2023–2025).

Its 6,740 t of CO₂ for 2025 is 2.4 times 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 280.7 kg CO₂, 2.3 times the type median of 122.2 kg. It logged 2,027 hours at sea against a median of 3,044 hours for its type that year. 6.6% of its 2025 emissions were at berth; the median for general cargo ships was 4.3%. Across 6 years with reported emissions, the highest was 2018 (8,161 t) and the lowest 2023 (1,153 t). Its efficiency percentile within the type went from 25 in 2018 to 28 in 2021 (lower is more efficient). Of the 5 comparable vessels listed below with a 2025 return, 4 reported a lower CO₂ per nautical mile than this vessel.

Efficiency against its own type2021

Position 91 of 326 qualifying general cargo ships by EEOI, at the 28th percentile. The dashed line is the type median, 22.6; this vessel reported 17.1.

EEOI divides emissions by transport work, which for this vessel and year was 285,558,343 tonne-miles over 15,654 nautical miles.

Reported CO₂ by year

Reported CO₂ in 2025 was 17.4% lower than in 2018, for EU/EEA voyages only.

From 2024 to 2025, emissions rose 59.8% and CO₂ per nautical mile fell 16.5%.Distance is missing for at least one of the two years, so activity and efficiency cannot be separated here.
