Sustainability of construction works - Environmental product declarations - Product Category Rules for concrete and concrete elements

2Scope / Description

This document complements the general rules for construction product category (Core Rules) as defined in EN 15804:2012+A2:2019 and is intended for use as a complementary product category rule (c-PCR) in conjunction with that standard. The c-PCR applies to products within the scope of CEN/TC 104 and CEN/TC 229, and may also be applicable to other concrete products provided they have product-specific c-PCRs. It covers concrete and concrete products for buildings and structures, excluding autoclaved aerated concrete and polymer-bonded concrete. In addition to the provisions in Annex G, it may also be used as guidance for fiber-reinforced concrete. The document defines the parameters to be reported, the types of Environmental Product Declarations (EPDs) and life cycle stages to be included in Life Cycle Inventory (LCI) and Life Cycle Impact Assessment (LCIA) rules, and the data quality criteria used in developing EPDs. In addition to the general provisions of EN 15804:2012+A2:2019, it establishes the following objectives for concrete and concrete products: defining system boundaries; specifying modeling and assessment of material-specific characteristics; setting allocation procedures for multi-output processes across the production chain; defining allocation rules for reuse and recycling; providing rules for LCI and the calculation of LCIA underlying the EPD; issuing guidance on determining the reference service life (RSL); providing guidance on constructing default scenarios; and providing guidance on default functional units for concrete products. This document is intended for use in assessing both the production phase and subsequent life cycle stages (from cradle to gate, with options) or the full life cycle (from cradle to grave), on the assumption that the objectives are correctly defined in the system boundaries description. Within the context of construction, the cradle-to-grave declaration provides a more comprehensive overview of the environmental impacts associated with concrete and concrete products.
