BBC RAINBOW against its type
Built in 2010, it is 3 years newer than the median general cargo ship on this register, which was built in 2007 (2,852 vessels with a known build year). It is one of 187 general cargo ships here under the Portugal flag, 6.1% of the 3,081 on the register. The reported port of registry changed: HONG KONG (2019–2021), then PANAMA (2022), then MADEIRA (2024–2025).
Its 4,740 t of CO₂ for 2025 is 1.7 times 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 247.1 kg CO₂, 2.0 times the type median of 122.2 kg. It logged 1,644 hours at sea against a median of 3,044 hours for its type that year. 5.3% of its 2025 emissions were at berth; the median for general cargo ships was 4.3%. Across 6 years with reported emissions, the highest was 2025 (4,740 t) and the lowest 2019 (1,407 t). Its efficiency percentile within the type went from 99 in 2020 to 100 in 2024 (lower is more efficient). Of the 6 comparable vessels listed below with a 2025 return, 5 reported a lower CO₂ per nautical mile than this vessel.

Efficiency against its own type2024
Position 2,850 of 2,858 qualifying bulk carriers by EEOI, at the 100th percentile. The dashed line is the type median, 7.9; this vessel reported 33.6.
EEOI divides emissions by transport work, which for this vessel and year was 135,306,226 tonne-miles over 20,388 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2025 was 236.9% higher than in 2019, for EU/EEA voyages only. No return is recorded for 2023, so the series has gaps.
From 2024 to 2025, emissions rose 4.3% and CO₂ per nautical mile rose 10.9%.Distance is missing for at least one of the two years, so activity and efficiency cannot be separated here.
