BR BROTHER: CO₂ emissions 2018–2025

BR BROTHER 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 5,451 gross tonnage it is smaller than 58% of the other 2,665 general cargo ships with a recorded tonnage. It is one of 34 general cargo ships here under the Comoros flag, 1.1% of the 3,081 on the register. Its MRV returns name it MERRY M for 2018–2021 and BR BROTHER for 2022–2025. The returns for 2018–2025 all give Moroni as port of registry.

Its 935 t of CO₂ for 2025 is 67% below 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 105.5 kg CO₂, 14% below the type median of 122.2 kg. It logged 907 hours at sea against a median of 3,044 hours for its type that year. 7.9% of its 2025 emissions were at berth; the median for general cargo ships was 4.3%. Across 7 years with reported emissions, the highest was 2022 (1,766 t) and the lowest 2021 (217 t). Its efficiency percentile within the type went from 76 in 2022 to 55 in 2024 (lower is more efficient). Of the 8 comparable vessels listed below with a 2025 return, 0 reported a lower CO₂ per nautical mile than this vessel.

Efficiency against its own type2024

Position 176 of 321 qualifying general cargo ships by EEOI, at the 55th percentile. The dashed line is the type median, 23.6; this vessel reported 25.0.

EEOI divides emissions by transport work, which for this vessel and year was 58,708,233 tonne-miles over 12,938 nautical miles.

Reported CO₂ by year

Reported CO₂ in 2025 was 62.4% higher than in 2018, for EU/EEA voyages only. No return is recorded for 2020, so the series has gaps.

From 2024 to 2025, emissions fell 36.4% and CO₂ per nautical mile fell 7.0%.Distance is missing for at least one of the two years, so activity and efficiency cannot be separated here.
