REBECCA S against its type
Built in 2007, it is 1 year older than the median container ship on this register, which was built in 2008 (3,088 vessels with a known build year). At 7,545 gross tonnage it is smaller than 97% of the other 3,000 container ships with a recorded tonnage. It is one of 307 container ships here under the Portugal flag, 8.8% of the 3,495 on the register. Its MRV returns name it SAMBA for 2018 and REBECCA S for 2019–2025. The reported port of registry changed: St.John's (2018), then Madeira (2019–2022), then Portugal (2023–2025).
Its 16,872 t of CO₂ for 2025 is close to the median of 16,359 t among the 2,234 container ships on this register that reported for 2025. Per nautical mile it emitted 221.9 kg CO₂, 59% below the type median of 545.6 kg. It logged 5,045 hours at sea against a median of 3,155 hours for its type that year. 6.4% of its 2025 emissions were at berth; the median for container ships was 3.2%. Across 8 years with reported emissions, the highest was 2025 (16,872 t) and the lowest 2019 (5,148 t). Its efficiency percentile within the type went from 99 in 2021 to 100 in 2025 (lower is more efficient). Of the 8 comparable vessels listed below with a 2025 return, 4 reported a lower CO₂ per nautical mile than this vessel.

Efficiency against its own type2025
Position 1,829 of 1,838 qualifying container ships by EEOI, at the 100th percentile. The dashed line is the type median, 14.2; this vessel reported 73.2.
EEOI divides emissions by transport work, which for this vessel and year was 230,556,026 tonne-miles over 76,035 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2025 was 36.6% higher than in 2018, for EU/EEA voyages only.
From 2024 to 2025, emissions rose 26.6% while distance sailed rose 23.6%and CO₂ per nautical mile rose 2.4%.That points mainly to how much the vessel sailed, rather than the other.
