The environmental performance of construction products and assemblies is a determinant factor for the environmental sustainability of buildings. Increasing willingness of stakeholders in the construction sector for green procurement, better-informed decisions and consideration of environmental aspects increase the need of transparent, objective and independent information on the environmental performance of construction products. Environmental product declarations (EPD) based on the European standard EN 15804 are used in the construction sector since 2012. In parallel, since 2011, the European Commission (EC) has developed a common method for the assessment of the environmental performance of products: the Product Environmental Footprint (PEF). After a pilot phase, the PEF method has evolved, and some updates were published in early 2019. The EN 15804 standard has also been revised, and therefore it is the ideal time to seek the harmonization of Life Cycle Assessment (LCA) methods. This paper presents a pioneer study applied to the construction sector that focus on the comparison between the PEF method (2019 updated) and the EPDs developed according to the Core rules for the product category of construction products presented in EN 15804 (EN 15804:2012+A1:2013, recently updated by EN 15804:2012+A1:2013 +A2:2019).
