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.
