JSP SLIDUR 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 9,962 gross tonnage it is smaller than 91% 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. Its MRV returns name it JSP SLIDUR for 2018, JUDITH BORCHARD for 2019, JSP SLIDUR for 2020–2021 and WEC JAN STEEN for 2022–2025. The reported port of registry changed: Limassol (2018), then Madeira (2020–2025).
Its 17,248 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 228.8 kg CO₂, 58% below the type median of 545.6 kg. It logged 6,021 hours at sea against a median of 3,155 hours for its type that year. 3.6% of its 2025 emissions were at berth; the median for container ships was 3.2%. Across 8 years with reported emissions, the highest was 2025 (17,248 t) and the lowest 2018 (6,937 t). Its efficiency percentile within the type went from 99 in 2019 to 96 in 2025 (lower is more efficient). Of the 8 sister ships listed below with a 2025 return, 0 reported a lower CO₂ per nautical mile than this vessel.

Efficiency against its own type2025
Position 1,755 of 1,838 qualifying container ships by EEOI, at the 96th percentile. The dashed line is the type median, 14.2; this vessel reported 47.6.
EEOI divides emissions by transport work, which for this vessel and year was 362,361,975 tonne-miles over 75,386 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2025 was 148.6% higher than in 2018, for EU/EEA voyages only.
From 2024 to 2025, emissions rose 7.3% while distance sailed rose 1.0%and CO₂ per nautical mile rose 6.3%.That points mainly to how efficiently it sailed, rather than the other.
