Other frequent issues involve electricity modelling, transport assumptions, units, allocation, cut-off criteria, and mismatches between the LCA model and final EPD report."},{"q":"How can I check whether my EPD follows the applicable PCR requirements?","a":"Build a PCR conformance checklist before modelling begins. Check the scope, modules, declared unit, data quality, scenarios, impact reporting structure, and required reporting format against the applicable PCR and programme operator requirements."},{"q":"What should the EPD background report document before submission?","a":"The background report should clearly document the modelling logic, assumptions, exclusions, data sources, conversion rules, and methodological choices. Each major assumption should be explicit, justified, and linked to primary data, secondary sources, or PCR rules."},{"q":"How can I improve the quality of my EPD data and scenarios?","a":"Report every database and version used, distinguish primary from secondary data, and assess representativeness, completeness, consistency, and temporal relevance. Justify end-of-life, service-life, maintenance, transport, installation, energy, and use-stage assumptions with product documentation, engineering input, industry references, or client records."},{"q":"What final checks should I complete before submitting an EPD for verification?","a":"Reconcile every reported indicator, unit, module, assumption, and result with the final LCA model and background report.
