ROBERTO against its type
Built in 2020, it is 7 years newer than the median gas carrier on this register, which was built in 2013 (530 vessels with a known build year). At 48,714 gross tonnage it is larger than 95% of the other 525 gas carriers with a recorded tonnage. It is one of 106 gas carriers here under the Singapore flag, 15.4% of the 688 on the register. The returns for 2020–2025 all give Singapore as port of registry.
Its 7,329 t of CO₂ for 2025 is 23% above the median of 5,974 t among the 363 gas carriers on this register that reported for 2025. Per nautical mile it emitted 333.7 kg CO₂, 30% above the type median of 256.2 kg. It logged 1,549 hours at sea against a median of 1,943 hours for its type that year. 1.2% of its 2025 emissions were at berth; the median for gas carriers was 3.8%. Across 3 years with reported emissions, the highest was 2025 (7,329 t) and the lowest 2021 (3,487 t). Its efficiency percentile within the type went from 11 in 2020 to 15 in 2025 (lower is more efficient). The one comparable vessel listed below with a 2025 return reported a higher or equal CO₂ per nautical mile.

Efficiency against its own type2025
Position 44 of 292 qualifying gas carriers by EEOI, at the 15th percentile. The dashed line is the type median, 27.9; this vessel reported 14.8.
EEOI divides emissions by transport work, which for this vessel and year was 495,545,639 tonne-miles over 21,962 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2025 was 72.5% higher than in 2020, for EU/EEA voyages only. No return is recorded for 2022, 2023, 2024, so the series has gaps.
From 2021 to 2025, emissions rose 110.2% while distance sailed rose 128.9%and CO₂ per nautical mile fell 8.2%.That points mainly to how much the vessel sailed, rather than the other.
