BUXCLIFF: CO₂ emissions 2018–2025

BUXCLIFF against its type

Built in 2001, it is 7 years older than the median container ship on this register, which was built in 2008 (3,088 vessels with a known build year). At 72,760 gross tonnage it is larger than 63% of the other 3,000 container ships with a recorded tonnage. It is one of 976 container ships here under the Liberia flag, 27.9% of the 3,495 on the register. The same builder is recorded for 660 other vessels here, 231 of them container ships. Its MRV returns name it BUXCLIFF for 2018–2023 and MSC KERRY VII for 2024–2025. The reported port of registry changed: MADEIRA (2018–2023), then MONROVIA (2024–2025).

Its 5,300 t of CO₂ for 2025 is 68% 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 766.0 kg CO₂, 40% above the type median of 545.6 kg. It logged 471 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 2020 (51,303 t) and the lowest 2025 (5,300 t). Its efficiency percentile within the type went from 52 in 2018 to 48 in 2025 (lower is more efficient). Of the 8 sister ships listed below with a 2025 return, 8 reported a lower CO₂ per nautical mile than this vessel.

Efficiency against its own type2025

Position 877 of 1,838 qualifying container ships by EEOI, at the 48th percentile. The dashed line is the type median, 14.2; this vessel reported 13.7.

EEOI divides emissions by transport work, which for this vessel and year was 386,840,146 tonne-miles over 6,919 nautical miles.

Reported CO₂ by year

Reported CO₂ in 2025 was 88.3% lower than in 2018, for EU/EEA voyages only.

From 2024 to 2025, emissions fell 85.0% while distance sailed fell 85.3%and CO₂ per nautical mile rose 2.2%.That points mainly to how much the vessel sailed, rather than the other.
