JASPER WIND against its type

Built in 2009, it is 1 year newer than the median container ship on this register, which was built in 2008 (3,088 vessels with a known build year). At 7,500 gross tonnage it is smaller than 98% of the other 3,000 container ships with a recorded tonnage. It is one of 73 container ships here under the Antigua and Barbuda flag, 2.1% of the 3,495 on the register. The same builder is recorded for 30 other vessels here, 6 of them container ships. Its MRV returns name it JSP MISTRAL for 2018–2024 and JASPER WIND for 2025. The returns for 2024–2025 all give St. John´s as port of registry.

Its 4,473 t of CO₂ for 2025 is 73% 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 216.1 kg CO₂, 60% below the type median of 545.6 kg. It logged 2,356 hours at sea against a median of 3,155 hours for its type that year. 4.5% of its 2025 emissions were at berth; the median for container ships was 3.2%. Across 8 years with reported emissions, the highest was 2018 (17,311 t) and the lowest 2025 (4,473 t). Its efficiency percentile within the type went from 88 in 2018 to 94 in 2024 (lower is more efficient). The one sister ship listed below with a 2025 return reported a higher or equal CO₂ per nautical mile.

Reported CO₂ by year

Reported CO₂ in 2025 was 74.2% lower than in 2018, for EU/EEA voyages only.

From 2024 to 2025, emissions fell 52.4% and CO₂ per nautical mile fell 9.1%.Distance is missing for at least one of the two years, so activity and efficiency cannot be separated here.
