CSTAR VOYAGER against its type
Built in 2003, it is 6 years older than the median vessel in the other ship types category on this register, which was built in 2009 (451 vessels with a known build year). At 23,132 gross tonnage it is larger than 82% of the other 436 vessels in the other ship types category with a recorded tonnage. It is one of 53 vessels in the other ship types category here under the Panama flag, 10.6% of the 499 on the register. The same builder is recorded for 146 other vessels here, one of them a vessel in the other ship types category. Its MRV returns name it MARIA LUISA for 2018–2023 and CSTAR VOYAGER for 2024–2025. The reported port of registry changed: St Johns (2018–2019), then St. John's (2020–2022), then Madeira (2023), then Panama (2024–2025).
Its 12,804 t of CO₂ for 2024 is 2.0 times the median of 6,327 t among the 269 vessels in the other ship types category on this register that reported for 2024. Per nautical mile it emitted 286.1 kg CO₂, 26% above the type median of 226.4 kg. It logged 3,592 hours at sea against a median of 2,435 hours for its type that year. 4.6% of its 2024 emissions were at berth; the median for vessels in the other ship types category was 3.3%. Across 7 years with reported emissions, the highest was 2021 (16,166 t) and the lowest 2018 (2,085 t). The one comparable vessel listed below with a 2024 return reported a lower CO₂ per nautical mile.
No EU/EEA voyages were reported for 2025: zero CO₂ and zero time at sea, left out of the trend and of any ranking.

Efficiency against its own type2024
Position 22 of 155 qualifying other ship typess by EEOI, at the 14th percentile. The dashed line is the type median, 38.0; this vessel reported 21.7.
EEOI divides emissions by transport work, which for this vessel and year was 590,300,599 tonne-miles over 44,758 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2024 was 514.2% higher than in 2018, for EU/EEA voyages only.
From 2023 to 2024, emissions rose 13.1% and CO₂ per nautical mile fell 6.4%.Distance is missing for at least one of the two years, so activity and efficiency cannot be separated here.
