7. Allocation and Co-product Handling

rule_id	Applies to	Rule	source_ids
allocation_avoidance	multi-output foreground processes	First avoid allocation through process subdivision, species-separated records, and direct assignment of utilities, chemicals, packaging, wastes, and emissions to the operation that causes them.	eu-pef-2021-2279
allocation_species	rabbit and hare production	Do not transfer rabbit burdens to hare output or hare burdens to rabbit output when species-specific measured records are available; disclose any shared-service allocation between species.	eu-pef-2021-2279
allocation_output_status	blood, skins, organs, fat, bones, and trimmings	Determine the product, co-product, or waste status of each segregated output from its documented quality, destination, and contractual disposition; do not infer a useful co-product solely from its physical presence.	eu-jrc-sa-bref, eu-pef-2021-2279
allocation_physical_relation	unavoidable co-product allocation	Where subdivision cannot avoid allocation, use a documented underlying physical relationship that reflects how inputs and outputs change; do not select mass merely because mass data are available.	eu-pef-2021-2279
allocation_economic_relation	co-products without a defensible physical relation	Use an economic relationship only when a defensible physical relationship cannot be established, and retain the price source, averaging period, currency basis, market, and sensitivity disclosure.	eu-pef-2021-2279
allocation_waste_treatment	waste outputs and treatment	Assign collection, handling, and treatment burdens to each documented waste destination once; apply no avoided-burden credit unless the selected study method explicitly requires it and the assumption is disclosed.	eu-pef-2021-2279
allocation_shared_services	shared water, energy, refrigeration, sanitation, and wastewater services	Prefer submetering or operational logs; otherwise use a documented causal driver such as operating time, cleaned area, thermal load, wastewater volume, or product mass only where that driver represents consumption.	eu-jrc-sa-bref, eu-pef-2021-2279
allocation_disclosure	reported dataset	Report the allocation hierarchy, equations, drivers, values, co-product destinations, unresolved data gaps, and sensitivity results so that no measured input or output is counted twice or omitted.	eu-pef-2021-2279
