CARLOTA B against its type
Built in 2007, it is 1 year older than the median container ship on this register, which was built in 2008 (3,088 vessels with a known build year). At 7,852 gross tonnage it is smaller than 96% 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 68 other vessels here, 18 of them container ships. Its MRV returns name it DORIS SCHEPERS for 2019–2021 and CARLOTA B for 2022–2025. The returns for 2019–2025 all give Madeira as port of registry.
Its 17,005 t of CO₂ for 2025 is close to the median of 16,359 t among the 2,234 container ships on this register that reported for 2025. Per nautical mile it emitted 201.9 kg CO₂, 63% below the type median of 545.6 kg. It logged 6,161 hours at sea against a median of 3,155 hours for its type that year. 3.3% of its 2025 emissions were at berth; the median for container ships was 3.2%. Across 7 years with reported emissions, the highest was 2019 (21,910 t) and the lowest 2024 (14,887 t). Its efficiency percentile within the type went from 100 in 2019 to 98 in 2025 (lower is more efficient). Of the 7 sister ships listed below with a 2025 return, 1 reported a lower CO₂ per nautical mile than this vessel.

Efficiency against its own type2025
Position 1,805 of 1,838 qualifying container ships by EEOI, at the 98th percentile. The dashed line is the type median, 14.2; this vessel reported 56.5.
EEOI divides emissions by transport work, which for this vessel and year was 300,863,411 tonne-miles over 84,216 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2025 was 22.4% lower than in 2019, for EU/EEA voyages only.
From 2024 to 2025, emissions rose 14.2% while distance sailed rose 14.7%and CO₂ per nautical mile fell 0.4%.That points mainly to how much the vessel sailed, rather than the other.
