KING JOY 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 11,927 gross tonnage it is larger than 68% 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. Its MRV returns name it SANNA for 2018, TRANSWIND for 2019–2023 and KING JOY for 2024–2025. The reported port of registry changed: Valetta (2018), then Madeira (2019–2021), then Monrovia (2022–2023), then BRIDGETOWN (2024), then San Marino (2025).
Its 3,192 t of CO₂ for 2025 is 13% above 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 165.4 kg CO₂, 35% above the type median of 122.2 kg. It logged 2,122 hours at sea against a median of 3,044 hours for its type that year. 6.7% 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 2020 (7,401 t) and the lowest 2023 (556 t). Its efficiency percentile within the type went from 90 in 2024 to 16 in 2025 (lower is more efficient). Of the 5 comparable vessels listed below with a 2025 return, 2 reported a lower CO₂ per nautical mile than this vessel.

Efficiency against its own type2025
Position 80 of 479 qualifying general cargo ships by EEOI, at the 16th percentile. The dashed line is the type median, 29.4; this vessel reported 19.1.
EEOI divides emissions by transport work, which for this vessel and year was 167,113,613 tonne-miles over 19,293 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2025 was 15.3% lower than in 2018, for EU/EEA voyages only.
From 2024 to 2025, emissions rose 112.0% while distance sailed rose 109.7%and CO₂ per nautical mile rose 1.1%.That points mainly to how much the vessel sailed, rather than the other.
