ZIRCON against its type
Built in 1993, it is 17 years older than the median oil tanker on this register, which was built in 2010 (2,896 vessels with a known build year). At 5,045 gross tonnage it is smaller than 100% of the other 2,841 oil tankers with a recorded tonnage. It is one of 29 oil tankers here under the Cyprus flag, 0.8% of the 3,548 on the register. Its MRV returns name it ZIRCON for 2018–2019 and ZIRCONE for 2020–2025. The reported port of registry changed: Riga (2018–2019), then Limassol (2020–2025).
Its 3,806 t of CO₂ for 2025 is 52% below the median of 7,922 t among the 1,704 oil tankers on this register that reported for 2025. Per nautical mile it emitted 205.6 kg CO₂, 49% below the type median of 403.2 kg. It logged 2,201 hours at sea against a median of 2,030 hours for its type that year. 6.4% of its 2025 emissions were at berth; the median for oil tankers was 7.8%. Across 8 years with reported emissions, the highest was 2021 (7,827 t) and the lowest 2025 (3,806 t). The one comparable vessel listed below with a 2025 return reported a lower CO₂ per nautical mile.

Reported CO₂ by year
Reported CO₂ in 2025 was 29.4% lower than in 2018, for EU/EEA voyages only.
From 2024 to 2025, emissions fell 33.4% and CO₂ per nautical mile rose 5.4%.Distance is missing for at least one of the two years, so activity and efficiency cannot be separated here.
