MANISA SILVANA 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). At 5,581 gross tonnage it is smaller than 57% of the other 2,665 general cargo ships with a recorded tonnage. It is one of 187 general cargo ships here under the Portugal flag, 6.1% of the 3,081 on the register. The returns for 2021–2025 all give Madeira as port of registry.
Its 4,021 t of CO₂ for 2025 is 43% above 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 135.3 kg CO₂, 11% above the type median of 122.2 kg. It logged 3,438 hours at sea against a median of 3,044 hours for its type that year. 12.7% 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 2025 (4,021 t) and the lowest 2021 (1,702 t). Of the 8 comparable vessels listed below with a 2025 return, 8 reported a lower CO₂ per nautical mile than this vessel.

Reported CO₂ by year
Reported CO₂ in 2025 was 136.3% higher than in 2021, for EU/EEA voyages only.
From 2024 to 2025, emissions rose 18.0% and CO₂ per nautical mile fell 5.4%.Distance is missing for at least one of the two years, so activity and efficiency cannot be separated here.
