BREB COUNTESS against its type
Built in 2009, it is 2 years newer than the median general cargo ship on this register, which was built in 2007 (2,852 vessels with a known build year). At 5,630 gross tonnage it is smaller than 56% 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 3,894 t of CO₂ for 2025 is 38% 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 147.6 kg CO₂, 21% above the type median of 122.2 kg. It logged 3,020 hours at sea against a median of 3,044 hours for its type that year. 8.1% 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 2020 (6,006 t) and the lowest 2025 (3,894 t). Of the 7 comparable vessels listed below with a 2025 return, 7 reported a lower CO₂ per nautical mile than this vessel.

Efficiency against its own type2024
Position 35 of 155 qualifying other ship typess by EEOI, at the 22nd percentile. The dashed line is the type median, 38.0; this vessel reported 24.7.
EEOI divides emissions by transport work, which for this vessel and year was 195,361,504 tonne-miles over 33,175 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2025 was 12.6% lower than in 2018, for EU/EEA voyages only.
From 2024 to 2025, emissions fell 19.4% and CO₂ per nautical mile rose 1.3%.Distance is missing for at least one of the two years, so activity and efficiency cannot be separated here.
