IBU – a strong community

Currently (as of 2025), the IBU network comprises almost 400 companies and associations from all material sectors of the building materials industry, as well as from the fields of civil engineering and technical building equipment. Our members and declaration holders are mainly from Germany, but also from other European and non-European countries. Our members have published more than 3,000 EPDs since 2020.

Any association or individual company from the building materials industry can become a member. To make this possible for small and medium-sized enterprises, the IBU has developed various EPD models.

Membership positions building product manufacturers as pioneers in sustainable construction. With their EPDs, they demonstrate their commitment to continuously improving the environmental quality of their products. In addition, EPDs give them a competitive advantage by making it easier for manufacturers to access tendered construction projects.

IBU provides the following services for communication with EPD:

IBU exhibition package (plate and sticker in German)
IBU brochure
IBU flyer
EPD handover ceremonies
General support with communication
Press articles, text modules and gap texts for EPD handover ceremonies
Mutual recognition of EPDs
Two explanatory videos about EPDs and sustainable buildings

Your company or association wants to create EPDs at IBU and/or wants to become an IBU member?

Full membership

Associations as well as manufacturers and distributers from the construction industry can become full members:

Companies can become full members at IBU themselves or through their membership in an association that has already become a member at IBU. EPDs can then be created at IBU, provided the respective product is included in association’s product range.

Associations that are full members at IBU can transfer their right to create EPDs to their member companies (“further declaration owners”).

Associated membership

In case of an associated membership this option is not available. The associations decide to solely create Association EPDs, which means that their members cannot create their own EPDs or individualized EPDs through their association. Should a company wish to create their own EPD they have to become a full member at IBU.

Supporting membership

Any organization, company or person that wants to support the guiding principles of IBU can become a supporting member (without participating in the IBU Programme). In order to file for a supporting membership just send a letter/ email to the IBU office.

The board takes the decision on the membership and the final admission.
