At Insti­tut Bauen und Umwelt e.V., two dif­fer­ent EPDs are gen­er­al­ly offered: the IBU EPD and the “Core EPD”, in accor­dance with EN 15804. The pri­ma­ry dif­fer­ence between these two types of EPD is the extent of infor­ma­tion pro­vid­ed. The Core EPD con­tains only nor­ma­tive manda­to­ry required con­tents. Specif­i­cal­ly, this means that a Core EPD, among oth­er things, con­tains no data regard­ing the pro­duc­tion, prod­uct pro­cess­ing, con­di­tions of use, dis­pos­al, or the behav­iour of the prod­uct in unusu­al cir­cum­stances. Fur­ther, nei­ther Chap­ter 6 (Life Cycle Assess­ment Inter­pre­ta­tion) nor Chap­ter 7 (Evi­dence) are includ­ed. These miss­ing chap­ters sig­nif­i­cant­ly reduce the use­ful­ness of the EPD in com­par­i­son to a com­plete IBU EPD, which is why, in order to sup­ply infor­ma­tion that is as con­cise and com­pre­hen­sive as pos­si­ble, the IBU nor­mal­ly rec­om­mends the cre­ation of an IBU EPD.
