EPD: their meaning is fundamental
An environmental product declaration is a report created to internationally agreed standards (ISO 14025, EN 15804) which documents the ways in which a product
affects the environment throughout its whole life cycle, from the cradle (raw materials) to the grave of the product (disposal)
Life Cycle Assessment (LCA):
The core for environmental product declaration
EPD: Transparent, measured, verified communication
