MONTE ROSA EXPLORER against its type

It is one of 99 gas carriers here under the Panama flag, 14.4% of the 688 on the register. Its MRV returns name it MONTE ROSA EXPLORER for 2022 and PERTAMINA GAS AMARYLLIS for 2024–2025. The reported port of registry changed: Singapore (2022), then Panama (2024–2025).

Its 7,884 t of CO₂ for 2025 is 32% above the median of 5,974 t among the 363 gas carriers on this register that reported for 2025. Per nautical mile it emitted 986.3 kg CO₂, 3.8 times the type median of 256.2 kg. It logged 613 hours at sea against a median of 1,943 hours for its type that year. 1.1% of its 2025 emissions were at berth; the median for gas carriers was 3.8%. Across 3 years with reported emissions, the highest was 2022 (9,144 t) and the lowest 2024 (7,865 t). Its efficiency percentile within the type went from 2 in 2022 to 35 in 2025 (lower is more efficient). Of the 6 comparable vessels listed below with a 2025 return, 6 reported a lower CO₂ per nautical mile than this vessel.
