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. The focus is on convincing everyone that sustainability is the right choice. IBU´s environmental product declarations (EPDs) were created in close cooperation with construction and environmental authorities in Germany and international standardization processes. IBU is currently the only organization in Germany that verified consistently based on the international standards ISO14025 and EN 15804 for all kinds of construction products. In addition to manufacturers, independent experts from research, Germany´s Ministry of Construction, the German Environmental Agency (UBA), and health and environmental experts are involved in audits. The IBU EPD provides a lot of information, credibility, and acceptance. The institute’s over 240 members, from 22 different countries, from SMEs to global corporations, from more than 40 associations and over 100 different product categories, exemplify the enormous variety of products and branches that rely on EPDs to provide a neutral, independent, proven, and comprehensive information tool for detailing the environmental effects of products.
