GEMINI MAESTRO against its type
Built in 2007, it is the same age as the median general cargo ship on this register (build year 2007, 2,852 vessels with a known build year). At 5,164 gross tonnage it is smaller than 61% 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 returns for 2018–2025 all give Monrovia as port of registry.
Its 3,000 t of CO₂ for 2025 is close to 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 93.9 kg CO₂, 23% below the type median of 122.2 kg. It logged 3,592 hours at sea against a median of 3,044 hours for its type that year. 3.0% of its 2025 emissions were at berth; the median for general cargo ships was 4.3%. Across 8 years with reported emissions, the highest was 2021 (3,952 t) and the lowest 2020 (2,594 t). Of the 6 comparable vessels listed below with a 2025 return, 3 reported a lower CO₂ per nautical mile than this vessel.

Reported CO₂ by year
Reported CO₂ in 2025 was 1.7% lower than in 2018, for EU/EEA voyages only.
From 2024 to 2025, emissions rose 13.1% and CO₂ per nautical mile fell 13.5%.Distance is missing for at least one of the two years, so activity and efficiency cannot be separated here.
