AS CAROLINA against its type

Built in 2006, it is 2 years older than the median container ship on this register, which was built in 2008 (3,088 vessels with a known build year). At 28,927 gross tonnage it is smaller than 64% of the other 3,000 container ships with a recorded tonnage. It is one of 307 container ships here under the Portugal flag, 8.8% of the 3,495 on the register. The same builder is recorded for 983 other vessels here, 86 of them container ships. The returns for 2018–2025 all give Madeira as port of registry.

Its 14,912 t of CO₂ for 2020 is 11% below the median of 16,763 t among the 1,837 container ships on this register that reported for 2020. Per nautical mile it emitted 369.1 kg CO₂, 31% below the type median of 536.8 kg. It logged 3,501 hours at sea against a median of 2,806 hours for its type that year. 20.2% of its 2020 emissions were at berth; the median for container ships was 3.7%. Across 3 years with reported emissions, the highest was 2020 (14,912 t) and the lowest 2018 (14,324 t). Its efficiency percentile within the type went from 66 in 2018 to 73 in 2020 (lower is more efficient).

No EU/EEA voyages were reported for 2025: zero CO₂ and zero time at sea, left out of the trend and of any ranking.

Efficiency against its own type2020

Position 1,109 of 1,525 qualifying container ships by EEOI, at the 73rd percentile. The dashed line is the type median, 15.9; this vessel reported 23.7.

EEOI divides emissions by transport work, which for this vessel and year was 629,204,219 tonne-miles over 40,407 nautical miles.

Reported CO₂ by year

Reported CO₂ in 2020 was 4.1% higher than in 2018, for EU/EEA voyages only. No return is recorded for 2021, 2022, 2023, 2024, so the series has gaps.

From 2019 to 2020, emissions rose 0.3% while distance sailed rose 9.2%and CO₂ per nautical mile fell 8.1%.
