The ecoinvent database in Environmental Product Declarations (EPDs)

Currently, the increasing and efficient practice of Environmental Product Declarations (EPDs) in the construction and manufacturing sector requires standardized, accurate, non-misleading communication of environmental information. As such, international standards like ISO 14025 and ISO 21930, and the amended EN15804 standard (EN15804&A2:2019) for Europe, define the standardised format and nomenclature for the communication of data and the results of their use.

 

It is our vision that people worldwide have access to high-quality information to perform sustainability assessments easily and affordably. As the publisher of environmental information, we want to make sure that our products meet the requirements of widely recognised standards. Even more, we wish to offer our users data and information in formats that meet their needs and purposes. Therefore, the ecoinvent association is developing an additional system model to the ecoinvent database, dedicated to support the needs of EPD practitioners.

 

Specifically, the additional system model ‘Allocation, cut-off, EN15804’ adjusts all datasets included in the ecoinvent database to comply with the amended EN15804 standard (EN15804&A2:2019) and with ISO 14025 and ISO 21930. The system model has been developed according to guidelines of the Technical Committee CEN/TC 350 and the directive of the European Commission regarding the end-of-waste state. It includes inventory indicators describing resource use, waste categories and output flows, and information on biogenic carbon content, as well as a detailed overview of the assumptions and the calculation method for indicators. The calculation methodology for these indicators is developed by the ecoinvent team and Chris Foster, accredited verifier for the International EPD® System and for EPD Ireland, and is documented in detail. As such, the system model not only facilitates an easier, standard-compliant EPD practice, but also further promotes harmonization in the calculation of the indicators of the standard and supports accurate comparability of the results. In addition, the datasets in this system model can be provided in a format and nomenclature compliant with EN15804&A2:2019.

 

The ‘Allocation, cut-off, EN15804’ system model will soon be available as an add-on to licence holders of the ecoinvent database.
