RHOGAS against its type

Built in 2012, it is 1 year older than the median gas carrier on this register, which was built in 2013 (530 vessels with a known build year). At 8,009 gross tonnage it is smaller than 83% of the other 525 gas carriers with a recorded tonnage. It is one of 10 gas carriers here under the Antigua and Barbuda flag, 1.5% of the 688 on the register. Its MRV returns name it RHOGAS for 2018–2019, RHOGAS (RHOGAS) for 2020, RHOGAS for 2021, RHOGAS (RHOGAS) for 2022 and RHOGAS for 2023–2025. The reported port of registry changed: Saint John's (2019), then Saint John's (AG SJO) (2020), then Saint John's (2021), then Saint John's (AG SJO) (2022), then Saint John's (2023–2025).

Its 5,494 t of CO₂ for 2025 is close to the median of 5,974 t among the 363 gas carriers on this register that reported for 2025. Per nautical mile it emitted 220.9 kg CO₂, 14% below the type median of 256.2 kg. It logged 2,535 hours at sea against a median of 1,943 hours for its type that year. 15.7% of its 2025 emissions were at berth; the median for gas carriers was 3.8%. Across 8 years with reported emissions, the highest was 2019 (10,272 t) and the lowest 2022 (3,998 t). Its efficiency percentile within the type went from 92 in 2018 to 100 in 2024 (lower is more efficient). Of the 4 comparable vessels listed below with a 2025 return, 0 reported a lower CO₂ per nautical mile than this vessel.

Reported CO₂ by year

Reported CO₂ in 2025 was 38.0% lower than in 2018, for EU/EEA voyages only.

From 2024 to 2025, emissions fell 11.5% and CO₂ per nautical mile fell 9.3%.Distance is missing for at least one of the two years, so activity and efficiency cannot be separated here.
