BG ONYX 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 68 other vessels here, 18 of them container ships. Its MRV returns name it SUSAN BORCHARD for 2018, SUSAN for 2019–2020 and BG ONYX for 2021–2025. The reported port of registry changed: Saint John's (2019–2020), then Madeira (2021–2025).
Its 14,796 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 247.4 kg CO₂, 55% below the type median of 545.6 kg. It logged 4,112 hours at sea against a median of 3,155 hours for its type that year. 7.4% of its 2025 emissions were at berth; the median for container ships was 3.2%. Across 8 years with reported emissions, the highest was 2019 (18,639 t) and the lowest 2020 (9,483 t). Its efficiency percentile within the type went from 94 in 2018 to 99 in 2025 (lower is more efficient). Of the 5 sister ships listed below with a 2025 return, 4 reported a lower CO₂ per nautical mile than this vessel.

Efficiency against its own type2025
Position 1,818 of 1,838 qualifying container ships by EEOI, at the 99th percentile. The dashed line is the type median, 14.2; this vessel reported 62.9.
EEOI divides emissions by transport work, which for this vessel and year was 235,229,889 tonne-miles over 59,794 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2025 was 20.4% lower than in 2018, for EU/EEA voyages only.
From 2024 to 2025, emissions rose 21.4% while distance sailed rose 25.0%and CO₂ per nautical mile fell 2.9%.That points mainly to how much the vessel sailed, rather than the other.
