Maritime Emissions Tracking and Carbon Reporting
Build verifiable voyage-level emissions records and turn fragmented fuel logs into audit-ready reporting workflows.
Status: Foundation module for emissions ledger, controls, and evidence packaging.
Operational scope
Qail Blue is a reporting control layer, not just a dashboard. It enforces source traceability from voyage events to management and compliance outputs.
Voyage emissions ledger
Store every voyage fuel and activity record with immutable timestamps, data origin, and approval lineage.
Factor and method versioning
Version emission factors and calculation rules per reporting period so historical reports stay reproducible.
Data quality and exception queue
Flag missing route, fuel, or load fields before monthly close and track owner/SLA for each exception.
Audit evidence bundle
Export source rows, approval trail, method notes, and report snapshots for external and internal review.
Core KPIs and controls
| KPI | Formula | Use |
|---|---|---|
| Data completeness | Complete voyage records / total voyage records | Monthly close readiness |
| Emission intensity | CO2e / transport output unit | Efficiency trend and benchmark |
| Exception aging | Average days open for unresolved data exceptions | Control ownership discipline |
| Reconciliation variance | Abs(report fuel - source fuel) / source fuel | Source integrity check |
| Audit pack cycle time | Close date to evidence package issuance | Reporting agility and governance maturity |
Recommended close gate: do not finalize external reports when data completeness is below agreed threshold.
Data contract (minimum fields)
Voyage activity and fuel
- voyage_id, vessel_id, route_id, departure_arrival time
- fuel_type, fuel_quantity, fuel_source, unit_conversion
- payload/passenger context and operational notes
Reporting and governance
- factor_version, method_version, calculated_co2e
- reviewer_id, approver_id, signoff timestamps
- exception_code, correction_reason, source_document_ref
30-60-90 rollout
0-30 days
Define scope boundary, onboard fuel and route sources, and run first dry-run monthly close for pilot routes.
31-60 days
Activate exception ownership, implement approval workflow, and reconcile against operational ledgers.
61-90 days
Scale to full fleet, standardize report packs, and prepare external assurance-ready evidence exports.
Pilot success thresholds
- Data completeness >= 95% on pilot reporting scope
- All month-close exceptions assigned with owner and due date
- Reconciliation variance stable inside agreed tolerance
- Audit evidence package reproducible for prior period rerun
