IES: Additional requirements to comply with ISO 21930

EPDs based on IES PCR do not by default comply with ISO 21930. To claim compliance with ISO 21930, the following additional requirements, which are further described in subsequent sections, shall be met:

▪ Allocation requirements* for production scrap from A1-A3 in EN 15804 and ISO 21930 are not fully compatible; if this influences the results, the EPD cannot comply with ISO 21930 unless it can be justified that conservative assumptions have been made, see section 4.5 of this PCR.
▪ For EPDs of multiple products, compliance with ISO 21930 is only possible if variation between included products is lower than 10% for the results of all environmental impact indicators, see Section 2.2.2.1. Sector EPDs are exempt from this rule.
▪ To comply with ISO 21930, the indicators in ISO 21930 applicable for the geographical context of the EPD shall be declared.
▪ To comply with ISO 21930, the biogenic carbon content of product and packaging shall additionally be declared as kg CO2 eq. per product or declared unit (see Section 5.4.4).

*On the aspect of allocation, EN 15804 differs from ISO 21930, which in its guidance on modeling of module A states that useable output flow shall not be considered as co-products but shall be considered waste and no allocation to secondary material/fuels or energy shall be permitted” (Section 7.1.7.2.7 of ISO 21930). If this aspect of allocation influences the results of an EPD, the EPD cannot claim to comply with ISO 21930 unless it can be justified that a conservative assumption has been made (yielding higher results than a strict application of ISO 21930); if so, this shall be described in the EPD.
