Shorn greasy sheep wool at the producing farm gate

1. Scope and Applicability

This rule covers sheep/lamb fleece cut from live animals and transferred as greasy, unscoured wool at the producing farm gate. Optional fleece washing occurs on the animal before shearing. Post-shear scouring, degreasing, topmaking, pulled pelt wool, and goat or camelid hair are excluded. The CPC 02941 label is interpreted with the WCO Chapter 51 sheep/lamb definition of wool (un-cpc-2025; wco-hs-2017).

4. Measurement and Unit Rules

rule_id	Applies to	Required property	Required unit	Rule
net_greasy_mass	wool outputs	Mass 93a60a56-a3c8-11da-a746-0800200b9a66	kg	Weigh net as-received greasy wool after bale tare, not clean-wool yield (iwto-wool-lca-2016).
moisture_state	fleece	Mass fraction	%	Record moisture method, date and wet/dry basis; fleece-washed is not scoured.
flock_period	flock activity	Original activity property	original unit	Assign events to flock/cohort and year before per-kg normalization.
inventory_reference_normalization	all inventory rows	Actual flow property	exchange unit per reference flow	The inventory and collection aggregation fields below express final amounts per declared reference flow. Keep all raw collection records, original denominator qualifiers, route/period strata, unit conversions and allocation requirements. For each flow, first obtain its attributable amount in its own numerator unit using the existing rules; then divide by the measured accepted reference-output quantity of the same scope and multiply by the declared reference quantity. Do not mix species, states, gates or incompatible routes; count transfers and shared burdens once. A missing, zero or untraceable accepted-output denominator is a blocking data-quality issue. Keep provisional QA ranges on their explicitly stated bases; they are not conversion factors or production defaults. These are final foreground-package contributions, not replacements for stage quantitative references or stage-native unit-process datasets. Retain stage records separately. Compute normalized amount = attributable raw amount * declared reference quantity / measured accepted final reference-output quantity. Apply normalization exactly once.
stage_throughput_linkage	stage records and final package contributions	Actual flow property and its stated raw basis	retain native numerator and stage denominator units	Keep the original lot, event, cohort, period and stage denominators with their units. Reconstruct the attributable numerator A with measured stage quantity Q_stage and documented attribution before final normalization. If a quoted amount a_B corresponds to an explicit stage basis B_stage (for example, 1000 kg), use A = a_B * Q_stage / B_stage. If r_stage is already an intensity in exchange-unit per stage-unit, instead use A = r_stage * Q_stage, with no second division by B_stage. A raw attributable total is used directly. Final contribution = A * declared reference quantity / measured accepted final output. Convert compatible units explicitly and apply each attribution/allocation share exactly once; never treat a quoted amount or intensity as a raw total. Link stage transfers, losses, rejects, stocks, shared services and allocation to the same actual route, period and final-output stratum. For a 1000 kg basis retain 1000 kg explicitly. Do not assume unit yield, equal fresh/dried mass, equal head mass, equal dose quality or interchangeable gates. Missing links, unsupported unit conversion, zero denominators and untraceable allocation block dataset production. Stage-native datasets retain their own stage reference; package contributions are a separate projection.

5. System Boundary

Include managed sheep production, feed and pasture, manure, conditional pre-shear on-animal washing, shearing, farm airing/skirting, grade sorting, baling and producing-farm handover. Account for upstream purchased animal, feed, energy, water, fertilizer and packaging datasets once. Record rearing, replacements, culls and shared facilities across years. Stop before auction, post-farm freight, scouring, grease extraction and textile manufacture (iwto-wool-lca-2016).

7. Allocation and Co-product Handling

rule_id	Applies to	Rule	source_ids
flock_outputs	fleece, live sheep/lambs, exported manure and other independent products	Prefer physical subdivision where separable; for shared flock burdens disclose and consistently apply a justified allocation such as period-specific economic value, with price and sensitivity. No zero-burden cull sheep or dual product/waste manure.	iwto-wool-lca-2016
period_link	breeding, replacement, growth, shearing and culling years	Link inputs, animal stocks, events and outputs across relevant years; amortize only with observed service/lifetime evidence. Assign animal-year burden once.	iwto-wool-lca-2016
shared_assets	pasture, housing, water system, shearing shed and equipment	Identify flock/shearing/baling consumers and service years; allocate shared use by documented hours, area or animal-time before product allocation; avoid node duplication.	iwto-wool-lca-2016
grade_accounting	accepted, downgraded and rejected fleece	Keep grade outputs and destinations separate; marketable downgrade is product, unsaleable skirtings waste, and fibre cannot be both.	iwto-wool-lca-2016

Concrete cards do not inherit numerical ranges from the former aggregate card. Determine quantities from original records, stock/meter reconciliation and the declared reference flow; no default quantity or numeric screen is supplied without evidence matching the identity, unit, period and boundary. Missing range evidence is a quality disclosure, not zero use or proof of completeness.

rule_id	Applies to	Rule	source_ids
allocation_residual_precedence	remaining common burden with no specified primary branch	Resolve any study-specific joint-product instruction in this PCR that has no specified primary branch using this precedence; retain an already explicitly prescribed category-specific primary method. First directly assign separable output-specific activities. For the remaining common burden B, use a physical driver d_i only when measured operation or biological-service records demonstrate the causal consumption represented by that driver. A product being weighable, valuable or lower grade alone is insufficient; do not switch arbitrarily between area, time, mass and revenue. For comparable grades receiving the same common handling, measured processed mass is applicable only with the same service demand, state and moisture basis demonstrated. Share a_i=d_i/sum(d_j); B_i=Ba_i. If no defensible causal physical driver exists for that common operation, use gate- and period-matched economic shares a_i=(q_ip_i)/sum(q_j*p_j), with the complete independently intended output set, compatible quantity/price units, currency, representative prices and values before output-specific downstream processing. Missing price or denominator evidence makes the allocated result incomplete, not a zero-priced product or a single-output system. Report shares summing to one and sensitivity to a material alternative; an alternative is not an interchangeable primary result. Waste, retained residues and internal transfers receive no co-product share, while their attributable production/handling burdens remain with the producing saleable route. Retain unallocated physical quantities and mass balances separately. This branch gives no automatic substitution credit; any separately scoped substitution analysis retains the gross inventory and its actual displaced-function evidence.	ghg-protocol-product-standard-2011

8. Foreground Data Collection, Calculation, and Quality Rules

Specific input identification before dataset completion

Identify the actual input for this operation from supplier specifications, equipment and primary records. This is a mandatory collection requirement, not an exchange. Before dataset completeness, represent each used material, formulated product, carrier or independently purchased service by one physically specific card with its native quantity/property; confirm a compatible UUID, or retain an explicit unresolved identity and do not claim a fully linked dataset. Do not substitute a conditional example for an unknown actual input, invent a recipe, omit required use or infer zero from missing records. Attribute shared use, reusable assets and inclusive services once; preserve the original stage/period and measured throughput link to final reference output. The former aggregate range is not a component limit or consumption default.

requirement_id	collection_protocol_id	Preserved collection scope
feed_specific_input	cp_flock_feed	Operation flock: Quantify purchased rations and grazed biomass by cohort, feed type, dry matter and year; owned-land feed production is linked once. Denominator and scope requirements：per kg greasy wool after flock-year attribution Raw quantity and calculation requirements: Use separate feed-supply, intake and loss ledgers under calc_feed_supply_and_intake. The quantity carrying feed-production burden includes in-boundary refusals, spoilage and uneaten feed; it is not reduced to animal intake. Retain source, species/cohort, phase and original mass/moisture basis. Calculate the final contribution with inventory_reference_normalization and stage_throughput_linkage exactly once. Original collection denominator kind: reference_flow. Original quantity method: Calculate the attributable final-package exchange under inventory_reference_normalization and stage_throughput_linkage using reconciled feed-supply records that retain in-boundary losses and their production burden.
shear_energy_specific_input	cp_wash_shear	Operation shearing: Record electric or fuel-powered clippers and related equipment by carrier and event. Denominator and scope requirements：per kg captured fleece Raw quantity and calculation requirements: meter or equipment log per event Original collection denominator kind: process_output. Original quantity method: Calculate the attributable final-package exchange under inventory_reference_normalization and stage_throughput_linkage using the matched raw records.
bale_material_specific_input	cp_grade_bale	Operation baling: Record actual textile, film, ties and labels; determine reuse cycles from farm records. Denominator and scope requirements：per kg net greasy wool at farm gate Raw quantity and calculation requirements: net material consumed per bale, net of documented reuse Original collection denominator kind: reference_flow. Original quantity method: Calculate the attributable final-package exchange under inventory_reference_normalization and stage_throughput_linkage using the matched raw records.

Route-specific energy identification requirements

Select energy exchanges from the actual product state, operation, equipment and supply records. The conditional cards below are not a mandatory or exhaustive fuel list. For each requirement, document applicability and the used carrier, supplier, service period, native quantity and allocation; add a separate physically specific card and verify its UUID for any actual input not yet represented. An unidentified input remains an explicit completeness gap, never a zero or a generic energy exchange. Evidence of manual work, ambient drying or a bypass can justify non-use only for the affected operation. Preserve every required operation even when no example card is supplied.

Separate purchased supply from on-site conversion. Link self-generated electricity internally to the foreground generator and count its actual fuel and emissions there once; do not also charge a purchased-electricity supply for the same internal transfer. Likewise do not count supplier-side fuel again with purchased heat. Reconcile shared meters and contractor-included energy against existing cards, with one physical quantity assigned once. Retain source quantities, output throughput, shared-service allocation and excluded post-gate activities. For each carrier, apply period/output attribution once and scale to the declared reference quantity using matched accepted final output in the same product unit; do not normalize an already normalized amount again. Process-native intensities require a measured throughput link to that final output. These requirements do not set a consumption default or certify dataset completeness.

requirement_id	collection_protocol_id	Required operation and evidence
flock_energy_identification	cp_water_energy	Flock-year housing and manure machinery, excluding separately represented shearing. Select carriers from actual equipment records; pasture husbandry alone does not establish fuel use.

calc_pathway_emissions	flock	Use species- and management-compatible methods and retain disaggregated pathway totals. Convert N2O-N to N2O by 44/28 and NH3-N to NH3 by 17/14 exactly once; already molecular masses are not reconverted. Check methane against the documented available-carbon/methane-potential balance and nitrogen losses against each stage's available N. Indirect formation from previously volatilised N is a downstream transformation, not a second source-stage N loss. Attribute and normalize once; do not duplicate linked treatment or fate-model emissions. Use matched raw-period quantities before allocation for physical screens: CH4 mass × 12/16 must not exceed the carbon available to the represented pathway; source-stage NH3 mass × 14/17 plus direct N2O mass × 28/44 and other source N losses must not exceed that stage's available N, after accounting for stocks and transfers. Bound each indirect N2O-N calculation by its documented volatilised or leached N precursor, not by subtracting that downstream transformation again from the source ledger. These are conservation checks, not emission factors or an empirical per-product range.	cp_pathway_emissions	kg named compound per final reference flow	ipcc-livestock-2019; review-eea-manure-2023; review-ipcc-soils-2019
calc_feed_supply_and_intake	feed	Feed supply used by the represented operation = opening feed stock + receipts + on-site feed entering the operation - closing feed stock - documented unused returns or transfers out. Retain in-boundary spoilage, refusals and discarded leftovers in that supply. Actual intake = that supply - measured uneaten/discarded losses, after matching moisture/DM and period; use intake only for nutrition/metabolism. Opening stock retains its prior burden and is not another purchase. Trace any unused return or transfer and its burden destination; no automatic substitution credit. Attribute production once, through either the purchased-feed dataset or the represented on-site crop/collection node, never both for the same feed. Include actual waste treatment and manure contributions once, not as a second feed-production burden.	cp_feed_supply_and_intake	separate feed supply, intake and loss quantities, in matched as-fed/DM units	fao-feed-loss-accounting-2018
calc_manure_n2o_coverage	manure_n2o; review_flock_indirect_n2o; review_flock_soil_direct_n2o; review_flock_soil_indirect_n2o	For each actual manure stage, calculate direct N2O, volatilisation/deposition-derived indirect N2O, and applicable leaching/runoff-derived indirect N2O separately with documented species/system activity and factor basis. Convert N2O-N to molecular N2O by 44/28 once; do not reconvert molecular masses. Retain component worksheets. Where an existing N2O card covers both direct and indirect emissions, report their non-overlapping sum; where separate direct/indirect cards exist, assign each component once to its matching card and never also report the sum. Pasture deposition and land application use the managed-soil method, not a manure-storage factor. Assign foreground versus linked treatment/pasture coverage explicitly; a manure export does not erase earlier emissions, and already covered downstream emissions are not repeated. Account for stock, transfers and previous N losses in the nitrogen cascade; indirect N2O is a downstream transformation of its precursor, not a second source-stage N loss. Normalize attributed molecular masses once to the accepted reference output. Document inapplicability; absent pathway data are not zero.	cp_manure_n2o_coverage	kg molecular N2O by pathway and assigned existing card	ipcc-livestock-2019; review-ipcc-soils-2019
chemical_species_mass_accounting	elementary_nutrient_emissions	Final elementary exchanges use the mass of the identified substance and one actual receiving compartment. Keep nutrient/activity ledgers separate: species-specific N2O-N × 44/28 gives N2O, NH3-N × 17/14 gives NH3, nitrate-N × 62/14 gives nitrate, and phosphate-P × 95/31 gives phosphate. If the selected flow is elemental phosphorus instead, report kg P and convert phosphate mass by 31/95 only when that species basis is evidenced. Apply a conversion exactly once only when the method output is on the elemental basis; measured compound mass is not reconverted. Total nutrient losses cannot be assigned to a single species without a supported split, and residual/retained soil nutrient is not an emission. Keep direct/indirect pathway ledgers and avoid repeating a pathway already included in the chosen method or upstream inventory. Factor uncertainty ranges screen factors on their stated basis, not final compound amounts or admissible site emissions. Normalize the attributable compound mass once using the accepted reference quantity and the matched measured output. Unknown activity, identity or compartment remains an evidence gap and blocks a completeness claim.	cp_manure; cp_pathway_emissions; species-specific activity ledger, method pathway and factor basis, matched accepted output	Identity-specific exchanges and reconciled activity records

v_foreground_emission_responsibility	Actual operated nodes and linked services	Record responsibility for on-site fuel combustion and refrigerant leakage when applicable: either quantified foreground emissions or a named linked process explicitly covering them, never merely a fuel-supply or electricity-production input. Assess special-taxon biological and residue emissions using species/route evidence, without a generic livestock factor. Identify any unresolved pathway and withhold a completeness claim; document supported absence and prevent duplicate upstream/downstream accounting.
v_feed_supply_intake_separation	All feed inputs	Reject an upstream feed inventory reduced by in-boundary refusal, spoilage or discarded leftovers without retaining their production burden. Reconcile supply, intake, stock, transfers and loss destinations under calc_feed_supply_and_intake. Do not reuse intake as supplied feed, assume zero-burden on-site feed or grant automatic avoided-product credits.	fao-feed-loss-accounting-2018
v_manure_n2o_coverage	Applicable manure and managed-soil N pathways	Require explicit direct and indirect pathway coverage, stage N balances and molecular-mass conversion. Map each component to an existing N2O card or an explicitly covering linked process once under calc_manure_n2o_coverage. Missing indirect-pathway evidence prevents a completeness claim; no default zero or duplicate aggregate-plus-components.	ipcc-livestock-2019; review-ipcc-soils-2019
