BC CALLISTO against its type
Built in 2010, it is 3 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 20,238 gross tonnage it is larger than 80% of the other 2,665 general cargo ships with a recorded tonnage. It is one of 216 general cargo ships here under the Liberia flag, 7.0% 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 LOWLANDS BRABO for 2020, BC CALLISTO for 2021–2024 and NEREUS for 2025. The reported port of registry changed: PANAMA (2020), then Bridgetown (2021), then Panama (2022), then Bridgetown (2023–2024), then Monrovia (2025).
Its 716 t of CO₂ for 2025 is 75% 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 238.4 kg CO₂, 2.0 times the type median of 122.2 kg. It logged 312 hours at sea against a median of 3,044 hours for its type that year. 6.8% 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 2021 (4,084 t) and the lowest 2025 (716 t). Its efficiency percentile within the type went from 48 in 2020 to 29 in 2025 (lower is more efficient). Of the 4 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 141 of 479 qualifying general cargo ships by EEOI, at the 29th percentile. The dashed line is the type median, 29.4; this vessel reported 23.8.
EEOI divides emissions by transport work, which for this vessel and year was 30,156,632 tonne-miles over 3,005 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2025 was 79.6% lower than in 2020, for EU/EEA voyages only.
From 2024 to 2025, emissions fell 76.2% while distance sailed fell 75.3%and CO₂ per nautical mile fell 3.6%.That points mainly to how much the vessel sailed, rather than the other.
