AGROB BUCHTAL, JASBA & STEULER are very much aware of its responsibility in terms of green building, not least by within the framework of an Environmental Product Declaration (EPDs) in accordance with ISO 14025.

EPDs provide information on the use of energy and resources and the extent to which a product contributes to the greenhouse effect, acidification, over-fertilisation, destruction of the ozone layer and formation of smog. Furthermore, information is provided on the technical features required for estimating the performance of the construction product in the building, e.g. service life, thermal and sound insulation or the influence on indoor air quality. Institut Bauen und Umwelt e.V. (IBU) draws up Environmental Product Declarations in accordance with Type III (DIN EN ISO 14025). These Declarations are based on independent analyses and indicate the quality of a product as well as the company's sense of responsibility with regard to sustainable building.

IBU EPDs are based on the international ISO 14025 standard which applies across individual sectors and products. IBU is currently the only organisation in Germany which consistently issues declarations in accordance with this internationally valid standard.

An EPD therefore helps to evaluate the building as a whole. Consumption of resources and emissions across the entire manufacturing process are recorded and documented. The corresponding contribution to the greenhouse effect, over-fertilisation or acidification of water bodies can be quantified and evaluated using the Life Cycle Assessment.
