What’s behind an EPD? Presentation of two EPD examples

An EPD (Environmental Product Declaration) is a document that quantifies the environmental impact of a product throughout its life cycle, including greenhouse gases. Writing an EPD is a complex process involving several steps. Initially, factory production data, including recipe, electricity consumption, waste generation, and water consumption, must be collected. The second step involves inputting this data into a specialized software for a life cycle analysis. The final step is to generate an EPD from the software, which is then verified by a third party. This article will focus on describing the process of creating an EPD and the challenges for our industry. The various stages of a product’s life cycle will be explained, along with a description of the assumptions made during the creation of this type of document. To conclude, two concrete examples of EPDs will be presented, illustrating the drafting of this environmental tool.
