DIANA: CO₂ emissions 2019–2021

DIANA against its type

Built in 2007, it is the same age as the median general cargo ship on this register (build year 2007, 2,852 vessels with a known build year). At 9,611 gross tonnage it is larger than 63% of the other 2,665 general cargo ships with a recorded tonnage. It is one of 86 general cargo ships here under the Russia flag, 2.8% of the 3,081 on the register. The returns for 2019–2021 all give St Petersburg as port of registry.

Its 4,742 t of CO₂ for 2021 is 11% above the median of 4,268 t among the 1,316 general cargo ships on this register that reported for 2021. Per nautical mile it emitted 183.9 kg CO₂, close to the type median of 189.1 kg. It logged 2,183 hours at sea against a median of 2,017 hours for its type that year. 2.6% of its 2021 emissions were at berth; the median for general cargo ships was 3.9%. Across 3 years with reported emissions, the highest was 2021 (4,742 t) and the lowest 2019 (762 t). Its efficiency percentile within the type went from 55 in 2019 to 58 in 2021 (lower is more efficient). The one comparable vessel listed below with a 2021 return reported a lower CO₂ per nautical mile.

Efficiency against its own type2021

Position 189 of 326 qualifying general cargo ships by EEOI, at the 58th percentile. The dashed line is the type median, 22.6; this vessel reported 24.6.

EEOI divides emissions by transport work, which for this vessel and year was 192,920,260 tonne-miles over 25,790 nautical miles.

Reported CO₂ by year

Reported CO₂ in 2021 was 522.4% higher than in 2019, for EU/EEA voyages only.

From 2020 to 2021, emissions rose 292.7% while distance sailed rose 316.4%and CO₂ per nautical mile fell 5.7%.That points mainly to how much the vessel sailed, rather than the other.
