Calculation Rules
| rule_id | Applies to | Formula or rule | Inputs | Output | source_ids |
|---|---|---|---|---|---|
| accepted_net | nonconifer_fuelwood_handover | Derive accepted net as-received wood from actual gross mass minus measured tare and foreign matter; retain declared bark and water. Use only actually accepted qualified fuelwood as final denominator. | cp_dispatch | accepted net wood mass | unsd-nonconifer-fuelwood |
| normalize_actual_records | all inventory rows | Report attributable actual exchange quantity per 1 kg reference flow after actual-unit conversion and output/period attribution; divide by matched accepted net dispatch mass exactly once. Retain original basis and intermediate transfers. No fixed internal yield. | cp_management; cp_harvest; cp_residue; cp_preparation; cp_dispatch; cp_shared; cp_emissions_at_harvest_removal; cp_emissions_at_primary_preparation | reference-basis exchanges | fao-fuelwood-harvesting |
| matched_wood_balance | wood transfers and seasoning | For each matched lot reconcile wet wood, water, dry wood, bark, foreign matter, retained stock, rejects and product destinations. Apply measured wet-basis or dry-basis moisture definitions consistently; use site/species/form/moisture-matched volume bridges only. Separate evaporation from dry-matter deterioration and rain rewetting. | cp_harvest; cp_residue; cp_preparation; cp_dispatch | reconciled stock and material/water ledger | fao-fuelwood-harvesting |
| direct_releases | actual direct releases | Use the declared measured release or explicitly documented carrier/equipment/control-specific factor and its exact activity unit; identify substance and receiving medium. No downstream fuelwood-combustion emission is attributed here. Carbon stock reporting is not a negative emission without an evidenced inventory method. | cp_emissions_at_harvest_removal; cp_emissions_at_primary_preparation; cp_management; cp_harvest | direct release and separate carbon-stock records | fao-fuelwood-harvesting |
calculate_direct_release_ledger | stand_management; harvest_removal; residue_collection; primary_preparation; qualification_dispatch; shared_assets | For each unique event, substance and medium, obtain raw release E from measurement or the cited applicable method using activity A and a compatible factor EF; use E = A * EF only for a genuinely simple-factor method, after checking units and abatement scope. Do not add different substances/media; retain an unallocated raw-release ledger. Divide attributed burden totals once by matched positive final reference quantity R; do not renormalize final-reference intensities or allocate a shared event twice. Unexplained material residuals are not automatically emissions and missing factors are not zero. | cp_direct_release_stand_management; cp_direct_release_harvest_removal; cp_direct_release_residue_collection; cp_direct_release_primary_preparation; cp_direct_release_qualification_dispatch; cp_direct_release_shared_assets; existing emission cards; supplier coverage; reference quantity | Node/substance/medium-specific raw and attributed amounts and unresolved gaps |
Data Quality Requirements
| requirement_id | Applies to | Requirement | Evidence |
|---|---|---|---|
| species_source | all wood | Verify actual non-conifer botanical identity or disclosed mix, source part, untreated state and fuel/non-fuel destination; unknown species cannot be replaced by universal hardwood. | Source maps; supplier/source declarations; lot sampling |
| matched_quantity | all quantity bridges | Match scale calibration, moisture sample, stock dates, volume convention and conversion evidence to the same species/form/source and lot; quantify uncertainty and missing coverage. | cp_harvest; cp_residue; cp_preparation; cp_dispatch |
| period_completeness | managed/source and shared burdens | Cover actual establishment, each relevant harvest/regrowth, termination/replanting, reporting period and opening/closing stock; disclose observations rather than invented rotation/yield. | cp_management; cp_shared |
| quantitative_evidence | all Range cards | Provisional reasoned screens are replaceable QA prompts, not maximum allowed use, loss/yield coefficients or publication-grade defaults. Retain evidence for real values and explain observations outside a screen without deleting a real flow. | Raw records; actual factors; paired balances; uncertainty |
| concrete_identity | all exchange identities | Resolve actual carrier/service/product/waste/substance UUID with compatible property/unit/medium before final dataset exchange; a semantic umbrella is not one guessed exchange. Missing identity is disclosed, not manufactured. | Actual exchange detail and support verification |
9. Validation Rules
| rule_id | Applies to | Rule | source_ids |
|---|---|---|---|
| validate_reference | nonconifer_fuelwood_handover | Verify actual final producer gate and qualifiers, same card/reference identity and exactly 1 kg normalized net as-received qualified fuelwood. Packaging, soil and stones are not reference wood. | unsd-nonconifer-fuelwood |
| validate_source_choice | stand_management; harvest_removal; residue_collection | Resolve actual source and parent/delta evidence for every portion; do not count harvest and already-generated collection twice. Coppice cannot silently continue after removing its stool/root. Declare omitted processes and no-use evidence. | fao-woodfuel-planting; fao-dry-forest-silviculture |
| validate_balance | all wood and water | Reconcile actual incoming, intended products, waste, retained material, stock carryover, moisture and dry-matter changes; not all pre-gate mass is fixed to 1 kg. Volume/LHV conversions without matched evidence are gaps, not default constants. | fao-fuelwood-harvesting |
| validate_attribution | all outputs and periods | Require a complete intended-output set and every handoff, explicit attribution priority, stand/stool cohort ledger, shared consumers/service periods and unique burden owner; report sensitivity and prevent duplicate establishment/asset/energy charges. | fao-woodfuel-planting; fao-fuelwood-harvesting |
| validate_exchange | every inventory card | Expand actual zero/one/multiple umbrella exchanges from records, verify concrete UUID/property/unit and emitting substance/medium, preserve original physical bases and exactly-once conversion and accepted-mass normalization. Actual pollutants not covered by the two displayed air cards still require substance-specific records and evidence. | fao-fuelwood-harvesting |
validate_direct_release_coverage | stand_management; harvest_removal; residue_collection; primary_preparation; qualification_dispatch; shared_assets | For every activated node, reconcile its activity list against cp_direct_release_stand_management; cp_direct_release_harvest_removal; cp_direct_release_residue_collection; cp_direct_release_primary_preparation; cp_direct_release_qualification_dispatch; cp_direct_release_shared_assets: each relevant event must have quantified concrete elementary exchanges, evidenced upstream-service coverage, or evidenced absence of the activity. Missing/unknown is not zero and blocks data-package completeness. Check each actual substance/medium amount, method/factor units, concrete UUID and existing-card/service coverage for omissions or duplication; empty groups, purchased-electricity upstream emissions or another node's single CO2 card do not replace this node's on-site reconciliation. Shared-asset services must not create duplicate physical release events. |
