BRIGHTWAY against its type
Built in 2012, it is 2 years newer than the median oil tanker on this register, which was built in 2010 (2,896 vessels with a known build year). At 83,824 gross tonnage it is larger than 82% of the other 2,841 oil tankers with a recorded tonnage. It is one of 28 oil tankers here under the India flag, 0.8% of the 3,548 on the register. Its MRV returns name it BRIGHTWAY for 2018–2024 and CAVALRY for 2025. The reported port of registry changed: SINGAPORE (2018–2024), then Mumbai (2025).
Its 14,819 t of CO₂ for 2025 is 1.9 times the median of 7,922 t among the 1,704 oil tankers on this register that reported for 2025. Per nautical mile it emitted 579.5 kg CO₂, 44% above the type median of 403.2 kg. It logged 2,539 hours at sea against a median of 2,030 hours for its type that year. 9.8% of its 2025 emissions were at berth; the median for oil tankers was 7.8%. Across 8 years with reported emissions, the highest was 2022 (30,622 t) and the lowest 2019 (3,872 t). Its efficiency percentile within the type went from 43 in 2018 to 74 in 2025 (lower is more efficient). Of the 6 comparable vessels listed below with a 2025 return, 4 reported a lower CO₂ per nautical mile than this vessel.

Efficiency against its own type2025
Position 1,079 of 1,448 qualifying oil tankers by EEOI, at the 74th percentile. The dashed line is the type median, 7.5; this vessel reported 10.4.
EEOI divides emissions by transport work, which for this vessel and year was 1,419,438,697 tonne-miles over 25,571 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2025 was 92.2% higher than in 2018, for EU/EEA voyages only.
From 2024 to 2025, emissions rose 89.6% while distance sailed rose 83.7%and CO₂ per nautical mile rose 3.2%.That points mainly to how much the vessel sailed, rather than the other.
