BG RUBY against its type
Built in 2010, it is 2 years newer than the median container ship on this register, which was built in 2008 (3,088 vessels with a known build year). At 7,852 gross tonnage it is smaller than 96% 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. The same builder is recorded for 16 other vessels here, one of them a container ship. Its MRV returns name it MIRIAM BORCHARD for 2018, MIRIAM for 2019–2020 and BG RUBY for 2021–2025. The reported port of registry changed: Saint John's (2019–2020), then Madeira (2021–2025).
Its 13,246 t of CO₂ for 2025 is 19% below the median of 16,359 t among the 2,234 container ships on this register that reported for 2025. Per nautical mile it emitted 250.3 kg CO₂, 54% below the type median of 545.6 kg. It logged 4,024 hours at sea against a median of 3,155 hours for its type that year. 6.6% of its 2025 emissions were at berth; the median for container ships was 3.2%. Across 8 years with reported emissions, the highest was 2018 (18,892 t) and the lowest 2020 (11,657 t). Its efficiency percentile within the type went from 96 in 2018 to 97 in 2025 (lower is more efficient). Of the 8 comparable vessels listed below with a 2025 return, 6 reported a lower CO₂ per nautical mile than this vessel.

Efficiency against its own type2025
Position 1,779 of 1,838 qualifying container ships by EEOI, at the 97th percentile. The dashed line is the type median, 14.2; this vessel reported 51.5.
EEOI divides emissions by transport work, which for this vessel and year was 257,201,359 tonne-miles over 52,928 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2025 was 29.9% lower than in 2018, for EU/EEA voyages only.
From 2024 to 2025, emissions fell 8.8% while distance sailed fell 8.4%and CO₂ per nautical mile fell 0.5%.That points mainly to how much the vessel sailed, rather than the other.
