GOLDEN BONNIE against its type
Built in 2009, it is 2 years newer than the median general cargo ship on this register, which was built in 2007 (2,852 vessels with a known build year). At 20,236 gross tonnage it is larger than 79% of the other 2,665 general cargo ships with a recorded tonnage. It is one of 23 general cargo ships here under the San Marino flag, 0.7% of the 3,081 on the register. The same builder is recorded for 96 other vessels here, 38 of them general cargo ships. Its MRV returns name it GOLDEN BONNIE for 2018–2021, MERRY MARIE for 2022–2023 and STAR GATE for 2024–2025. The reported port of registry changed: Majuro (2022–2023), then SAN MARINO (2024–2025).
Its 1,509 t of CO₂ for 2025 is 46% 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 168.0 kg CO₂, 37% above the type median of 122.2 kg. It logged 797 hours at sea against a median of 3,044 hours for its type that year. 4.2% of its 2025 emissions were at berth; the median for general cargo ships was 4.3%. Across 8 years with reported emissions, the highest was 2022 (7,746 t) and the lowest 2021 (1,191 t). Its efficiency percentile within the type went from 3 in 2018 to 20 in 2024 (lower is more efficient). Of the 5 sister ships listed below with a 2025 return, 0 reported a lower CO₂ per nautical mile than this vessel.

Efficiency against its own type2024
Position 66 of 321 qualifying general cargo ships by EEOI, at the 20th percentile. The dashed line is the type median, 23.6; this vessel reported 13.9.
EEOI divides emissions by transport work, which for this vessel and year was 192,160,574 tonne-miles over 13,423 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2025 was 53.0% lower than in 2018, for EU/EEA voyages only.
From 2024 to 2025, emissions fell 43.7% and CO₂ per nautical mile fell 15.9%.Distance is missing for at least one of the two years, so activity and efficiency cannot be separated here.
