BOLTEN PANORAMA 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 15,861 gross tonnage it is larger than 74% of the other 2,665 general cargo ships with a recorded tonnage. It is one of 187 general cargo ships here under the Portugal flag, 6.1% of the 3,081 on the register. The same builder is recorded for 12 other vessels here, 4 of them general cargo ships. Its MRV returns name it MARGARET SW for 2018–2019 and BOLTEN PANORAMA for 2024–2025. The reported port of registry changed: PANAMA (2018–2019), then MADEIRA (2024–2025).
Its 8,038 t of CO₂ for 2025 is 2.9 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 325.6 kg CO₂, 2.7 times the type median of 122.2 kg. It logged 2,881 hours at sea against a median of 3,044 hours for its type that year. 8.6% of its 2025 emissions were at berth; the median for general cargo ships was 4.3%. Across 4 years with reported emissions, the highest was 2025 (8,038 t) and the lowest 2018 (2,167 t). Its efficiency percentile within the type went from 94 in 2018 to 96 in 2025 (lower is more efficient). Of the 2 sister ships listed below with a 2025 return, 2 reported a lower CO₂ per nautical mile than this vessel.

Efficiency against its own type2025
Position 462 of 479 qualifying general cargo ships by EEOI, at the 96th percentile. The dashed line is the type median, 29.4; this vessel reported 104.6.
EEOI divides emissions by transport work, which for this vessel and year was 76,834,831 tonne-miles over 24,691 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2025 was 270.9% higher than in 2018, for EU/EEA voyages only. No return is recorded for 2020, 2021, 2022, 2023, so the series has gaps.
From 2024 to 2025, emissions rose 103.1% while distance sailed rose 36.9%and CO₂ per nautical mile rose 48.3%.
