MERITA against its type
Built in 1985, it is 22 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 3,329 gross tonnage it is smaller than 73% 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.
Its 4,011 t of CO₂ for 2025 is 42% 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 90.8 kg CO₂, 26% below the type median of 122.2 kg. It logged 4,126 hours at sea against a median of 3,044 hours for its type that year. 9.9% of its 2025 emissions were at berth; the median for general cargo ships was 4.3%. Of the 8 comparable vessels listed below with a 2025 return, 6 reported a lower CO₂ per nautical mile than this vessel.
