A-03 Transport of raw materials to the manufacturer

Aspect A-03 Transport of raw materials to the manufacturer
Several raw materials are needed for manufacturing a building product. Depending on the number of raw materials and the availabilities of information from the suppliers, it may be difficult to account for the transport of raw materials in an accurate way. However, this stage of the life cycle may be relevant if the suppliers are located far away from the manufacturing plant.How should the transport of raw materials to the manufacturer be considered for a product LCA?

Provisions Transport of raw materials to the manufacturer should be included in Module A2 though it may be considered not relevant according to the cut-off rules (e.g. from EN 15804). Concerning the use of data, the provisions on data quality as given above should be considered (data quality, ILCD entry level, use of consistent data sources for comparative assertions).
Rules from:

EN 15804 Product stage
Within Modules A1–A3, transport is generally a significant impact only for materials with very low manufacturing impact – aggregates and timber, for example. Module A2 includes only transport to the manufacturing site from the previous production or extraction process. Earlier transport journeys are included in Module A1. Module A2 is mandatory in any cradle-to-gate EPD. National EPD programmes may have more specific rules on this topic. The main issue for the practitioner is collection of data on the distances between suppliers and the manufacturer. Generally speaking, these data should be available, and should be requested. However, if data are missing, it is recommended that default values, e.g. from national EPD programmes and PCR, be used; otherwise the practitioner’s own default values should be used (which should be subjected to sensitivity analysis).
