The Institut Bauen und Umwelt e. V. (IBU) is an association of building product manufacturers who have joined forces to operate an international environmental product declaration programme. The IBU is committed to sustainable building and believes that those who market their products as sustainable must also be able to prove this. This is precisely what the construction materials industry is doing in working with the IBU to create environment product declarations (EPD) – an internationally recognised and standardised tool for the sustainability certification of buildings.


IBU was created out of an initiative of manufacturers of construction products and components who decided to support the demand for more sustainability in the construction sector.


Environmental Product Declaration (EPD) form the data basis for an environmental building assessment.
