Produce CO₂, vessel-type CII, approximate FuelEU intensity and an EU ETS indicator from noon-report data, with visible data coverage and statutory-reporting boundaries.

Review CO₂ and CII calculations using fuel and distance data from daily reports. FuelEU indicators and ETS estimates support planning; they do not replace official verification or reporting.

IMO DCS addresses annual fuel consumption and related activity data; CII derives operational carbon intensity and an A–E rating; EU MRV covers voyage and annual verified greenhouse-gas reporting; and EU ETS applies route scope and allowance-surrender obligations. FuelEU Maritime is different again, assessing annual average well-to-wake GHG intensity of onboard energy and the compliance balance.

Faromo’s current aggregator maps noon-report fuel-oil and diesel consumption to HFO/MGO. It calculates vessel-type CII, produces an approximate CO₂-based WtW FuelEU value without CH₄ slip or N₂O, and applies the phase-in factor to CO₂ using a user-supplied EU-scope ratio. This internal summary does not replace a verified MRV/FuelEU report, a 2026 ETS allowance calculation or submission to THETIS-MRV, the FuelEU Database or GISIS.

## Period-based noon-report aggregation

Aggregate distance and HFO/MGO consumption for annual or quarterly periods within company and vessel scope.

## Vessel-type CII

Use the applicable DWT/GT metric, reference line and rating-boundary vector across 12 vessel types.

## Fuel-coverage warning

See a service-response warning when period BDN records contain fuel outside the HFO/MGO aggregator.

## Approximate FuelEU indicator

Produce an approximate CO₂-based WtW value for HFO/MGO using default energy and WtT factors, separated from the statutory CO₂eq result.

## Manual ETS scope estimate

Apply the reporting-period CO₂ and annual phase-in factor to a user-supplied 0–1 scope ratio.

## Internal review and PDF

Move a draft into an internally verified state and produce vessel- or fleet-level internal summary PDFs.

## Workflow

1. Choose period and scope assumption: Set vessel, year/quarter, capacity, vessel type and manual EU-scope ratio.
2. Aggregate operational data: Combine noon-report fuel and distance records within the period boundaries.
3. Review indicators and warnings: Assess CO₂, CII, approximate FuelEU and ETS estimates together with the BDN fuel-coverage warning.
4. Transfer separately to statutory workflows: Complete missing GHG and scope data, then run accredited-verifier and authorized-platform processes separately.

## Does Faromo calculate the statutory FuelEU compliance balance?

No. The current value is an approximate CO₂-based WtW indicator for HFO/MGO. Without CH₄ slip, N₂O, complete pathway/certification data, OPS and full voyage scope, it does not replace statutory FuelEU CO₂eq intensity or the compliance balance.

## Can the EU ETS allowance value be used for the 2026 obligation?

Not on its own. The current calculation relies on a user-entered scope ratio and CO₂. With CH₄ and N₂O entering ETS scope in 2026, verified MRV data, voyage scope and company aggregation are also required.

## For which vessel types is CII calculated?

The current engine supports bulk carrier, tanker, container, gas/LNG carrier, general and refrigerated cargo, combination carrier, ro-ro cargo/vehicle/passenger and cruise passenger profiles. The correct vessel type and applicable DWT/GT capacity must be supplied.

## Is the report submitted to THETIS-MRV or IMO GISIS?

No. The current service produces an internal report, stores an internal verification state and exports PDF summaries. It has no submission integration with THETIS-MRV, the FuelEU Database, Union Registry or Administration/GISIS.
