CONESTE against its type
Built in 2003, it is 5 years older than the median container ship on this register, which was built in 2008 (3,088 vessels with a known build year). At 9,990 gross tonnage it is smaller than 89% 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 180 other vessels here, 110 of them container ships. The reported port of registry changed: Saint John's (2018), then Gibraltar (2019–2021), then Madeira (2022–2025).
Its 13,945 t of CO₂ for 2025 is 15% below the median of 16,359 t among the 2,234 container ships on this register that reported for 2025. Per nautical mile it emitted 235.7 kg CO₂, 57% below the type median of 545.6 kg. It logged 4,116 hours at sea against a median of 3,155 hours for its type that year. 11.6% of its 2025 emissions were at berth; the median for container ships was 3.2%. Across 8 years with reported emissions, the highest was 2020 (18,532 t) and the lowest 2023 (5,722 t). Its efficiency percentile within the type was 99 in both 2018 and 2025. Of the 5 sister ships listed below with a 2025 return, 3 reported a lower CO₂ per nautical mile than this vessel.

Efficiency against its own type2025
Position 1,812 of 1,838 qualifying container ships by EEOI, at the 99th percentile. The dashed line is the type median, 14.2; this vessel reported 59.3.
EEOI divides emissions by transport work, which for this vessel and year was 235,317,584 tonne-miles over 59,164 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2025 was 3.8% higher than in 2018, for EU/EEA voyages only.
From 2024 to 2025, emissions rose 5.3% while distance sailed rose 5.6%and CO₂ per nautical mile fell 0.3%.That points mainly to how much the vessel sailed, rather than the other.
