Harmonisation of the environmental product declarations for wood products

Abstract

Environmental Product Declarations (EPD) are developed to compare materials and solutions in building level to achieve sustainable choices for the built environment. European standardisation body, CEN/TC 350 Sustainable Construction, have developed harmonised standard EN 15804 to create EPD s for the building products. Although harmonised standards exist, different methodologies and scenarios are used under different EPD operators and countries, which is not supporting sustainability assessment in building level. Identified challenges are e.g. generic background datasets, allocation in modules A1 A3, use of guarantees of origin for purchased energy, scenarios for transportation and installation, and end-of-life scenarios. Different assessment approaches challenge the assessment in the building level to achieve targets for sustainable buildings.
