DEMETER against its type
Built in 2005, it is 3 years older than the median container ship on this register, which was built in 2008 (3,088 vessels with a known build year). At 35,881 gross tonnage it is smaller than 60% 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 80 other vessels here, 41 of them container ships. Peter Döhle Schiffahrts-KG is linked to 65 vessels on this register. Its MRV returns name it DEMETER for 2018–2020 and INDEPENDENT PRIMERO for 2021–2025. The reported port of registry changed: Monrovia ﴾Liberia﴿ (2018), then Monrovia (2019–2022), then MADEIRA (2023–2025).
Its 40,015 t of CO₂ for 2025 is 2.4 times the median of 16,359 t among the 2,234 container ships on this register that reported for 2025. Per nautical mile it emitted 455.7 kg CO₂, 16% below the type median of 545.6 kg. It logged 5,301 hours at sea against a median of 3,155 hours for its type that year. 2.3% of its 2025 emissions were at berth; the median for container ships was 3.2%. Across 8 years with reported emissions, the highest was 2024 (43,572 t) and the lowest 2020 (13,607 t). Its efficiency percentile within the type went from 81 in 2018 to 75 in 2025 (lower is more efficient). Of the 6 sister ships listed below with a 2025 return, 5 reported a lower CO₂ per nautical mile than this vessel.

Efficiency against its own type2025
Position 1,372 of 1,838 qualifying container ships by EEOI, at the 75th percentile. The dashed line is the type median, 14.2; this vessel reported 22.6.
Across the 56 ranked vessels operated by Peter Döhle Schiffahrts-KG, the median percentile is 69. This vessel is less efficient than its own fleet median.
EEOI divides emissions by transport work, which for this vessel and year was 1,767,451,413 tonne-miles over 87,802 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2025 was 100.9% higher than in 2018, for EU/EEA voyages only.
From 2024 to 2025, emissions fell 8.2% while distance sailed fell 14.9%and CO₂ per nautical mile rose 7.9%.That points mainly to how much the vessel sailed, rather than the other.
