Sustainability of construction works – Environmental product declarations Part 2 – Core rules for aggregates intended to be used as unbound mixtures, railway ballast or armourstones

Scope

The TRs provide core product category rules for type III environmental declaration of natural, manufactured and recycled aggregates for building and civil engineering according to EN 17555, 13383 and 13450.

The TRs define the parameters to be reported, what EPD types (and life cycle stages) to be covered, what rules to be followed in order to generate Life Cycle Inventories (LCI) and conduct Life Cycle Impact Assessment (LCIA) and the data quality to be used in the development of EPDs.
In addition to the common parts of EN 15804:2012 + A2:2019, the TRs:
- define the system boundaries,
- define the modelling and assessment of material-specific characteristics;
- define allocation procedures for multi-output processes along the production chain,
- include the rules for calculating the LCI and the LCIA underlying the EPD;
- provide guidance for the determination of the reference service life (RSL).
- give guidance on the establishment of default scenarios.
