SUPERNOVA against its type
Built in 2012, it is 5 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 21,838 gross tonnage it is larger than 84% of the other 2,665 general cargo ships with a recorded tonnage. It is one of 310 general cargo ships here under the Panama flag, 10.1% of the 3,081 on the register. The same builder is recorded for 95 other vessels here. Its MRV returns name it SUPERNOVA for 2019–2021 and SUPERNOVA B for 2022–2025. The returns for 2019–2025 all give PANAMA as port of registry.
Its 4,260 t of CO₂ for 2025 is 1.5 times 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 268.7 kg CO₂, 2.2 times the type median of 122.2 kg. It logged 1,542 hours at sea against a median of 3,044 hours for its type that year. 4.8% of its 2025 emissions were at berth; the median for general cargo ships was 4.3%. Across 6 years with reported emissions, the highest was 2019 (4,615 t) and the lowest 2023 (1,544 t). Its efficiency percentile within the type went from 80 in 2019 to 7 in 2023 (lower is more efficient). Of the 6 comparable vessels listed below with a 2025 return, 3 reported a lower CO₂ per nautical mile than this vessel.

Efficiency against its own type2023
Position 25 of 331 qualifying general cargo ships by EEOI, at the 7th percentile. The dashed line is the type median, 21.1; this vessel reported 8.7.
EEOI divides emissions by transport work, which for this vessel and year was 176,833,906 tonne-miles over 6,468 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2025 was 7.7% lower than in 2019, for EU/EEA voyages only. No return is recorded for 2020, so the series has gaps.
From 2024 to 2025, emissions rose 84.2% and CO₂ per nautical mile rose 18.6%.Distance is missing for at least one of the two years, so activity and efficiency cannot be separated here.
