COLORADO EXPRESS against its type
Built in 2008, it is the same age as the median container ship on this register (build year 2008, 3,088 vessels with a known build year). At 75,579 gross tonnage it is larger than 66% of the other 3,000 container ships with a recorded tonnage. It is one of 7 container ships here under the United States flag, 0.2% of the 3,495 on the register. The same builder is recorded for 761 other vessels here, 355 of them container ships. Its MRV returns name it AL KHARJ for 2018–2020 and COLORADO EXPRESS for 2021–2025. The reported port of registry changed: Monrovia (2018–2020), then Norfolk, VA (2021–2025).
Its 3,471 t of CO₂ for 2025 is 79% 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 555.7 kg CO₂, close to the type median of 545.6 kg. It logged 423 hours at sea against a median of 3,155 hours for its type that year. 4.0% 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 (54,010 t) and the lowest 2025 (3,471 t). Its efficiency percentile within the type went from 41 in 2018 to 38 in 2024 (lower is more efficient). Of the 2 sister ships listed below with a 2025 return, 1 reported a lower CO₂ per nautical mile than this vessel.

Efficiency against its own type2024
Position 627 of 1,661 qualifying container ships by EEOI, at the 38th percentile. The dashed line is the type median, 15.4; this vessel reported 12.4.
EEOI divides emissions by transport work, which for this vessel and year was 2,376,280,517 tonne-miles over 50,496 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2025 was 91.4% lower than in 2018, for EU/EEA voyages only.
From 2024 to 2025, emissions fell 88.2% and CO₂ per nautical mile fell 4.5%.Distance is missing for at least one of the two years, so activity and efficiency cannot be separated here.
