CII, MRV, ETS and FuelEU are not the same calculation.

Faromo turns noon-report fuel and distance data into a period-based internal emissions record. It presents CO₂ and CII calculations, an approximate FuelEU CO₂-WtW indicator and an ETS estimate from a manually supplied EU-scope ratio, without claiming accredited-verifier output or platform submission.

One data source feeds four distinct obligations.

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.

The same fuel record creates a different control question under each regime.

When evaluating emissions software, asking “does it have CII?” is not enough. Vessel and route scope, fuel pathway, greenhouse-gas set, verification, deadline and submission channel must be verified separately for each regime.[1][2][3][4][5][6]

IMO DCS / CII

Connect annual fuel data to operational rating

For applicable ships of 5,000 GT and above, collect each fuel type and specified activity data; compare annual attained CII with required CII and manage the A–E rating and any required corrective action.

EU MRV

Prepare voyage data for a verified annual report

For applicable vessels and EEA voyages, collect CO₂, CH₄ and N₂O together with fuel, distance, time and related parameters under the monitoring plan, then prepare the report for accredited verification.

EU ETS

Separate route scope and greenhouse-gas coverage

Apply 100% coverage to emissions within ports and on intra-EU voyages and generally 50% to extra-EU legs, including CH₄ and N₂O alongside CO₂ from 2026.

FuelEU

Move from fuel mass to a complete WtW compliance balance

Use every energy source, WtT and TtW CO₂eq factor, engine/pathway and slip data to calculate annual average intensity, then connect it to the target and banking, borrowing or pooling decisions.

A single number labelled “MRV”, “ETS” or “FuelEU” does not establish compliance. The statutory result depends on applicable scope, complete GHG data, an approved monitoring plan and the authorized verification chain.

PILOT ACCEPTANCE GATE

What should be verified before connecting the emissions module to statutory workflows?

This control tests the move from software-produced calculations to a reliable statutory-reporting dataset. Maintain a separate acceptance record for each vessel and regime.[1][2][3][4][5][6]

  1. Scope Fix vessel and regime applicability: Determine GT, vessel type, flag, responsible company, EEA ports, voyage types and exemptions before the period starts.
  2. Voyage Recalculate voyage scope automatically: Derive 100%/50%/out-of-scope treatment from port call, departure-arrival and berth data, documenting exceptions.
  3. Fuel Reconcile every fuel and energy source: Verify that noon reports, BDNs, tank readings, flow meters, electricity and alternative-energy totals close for the same period.
  4. GHG Complete the CO₂, CH₄ and N₂O set: Record source and version for engine type, methane slip, N₂O, GWP and verified actual factors where applicable.
  5. CII Verify capacity and reference profile: Verify DWT or GT selection by vessel type, reference line, reduction factor and rating-boundary vector.
  6. Verification Separate internal review from accredited verification: State in UI and output that internal approval is not a verifier opinion, Administration decision or Document of Compliance.
  7. Timeline Manage four separate deadlines: Track FuelEU 31 January, MRV 31 March, the DCS 31 May/30 June chain and the ETS surrender calendar with ownership and evidence.
  8. Submission Reconcile platform outcomes back: Compare THETIS-MRV, FuelEU Database, Union Registry and Administration/GISIS outcomes with internal records and close discrepancies.

Faromo’s current emissions record is a planning and data-coverage tool. It does not replace accredited verification, statutory platform submission or a compliance document.

Scope and core capabilities

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.

Operational outcomes

  • Avoid mixing CII, MRV, ETS and FuelEU values in one generic “emissions” field.
  • See the fuel-coverage gap between noon reports and BDNs before statutory reporting.
  • Evaluate CII using the capacity metric and reference profile appropriate to the vessel type.
  • Separate internal planning indicators from verifier outcomes and statutory submissions.

Product evidence

From noon reports to an internal emissions summary

HFO/MGO consumption and distance are aggregated by period to produce CO₂, vessel-type CII, approximate FuelEU CO₂-WtW and an ETS indicator from a manually supplied EU-scope ratio.

Frequently asked questions

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.
