The IBU Procedure for the Creation and Verification of an EPD

EPDs from the IBU are created in a three-step process involving different entities. The goal of this process is to create transparency, and, through strong participation of the public and independent third parties, strengthen trust in the declaration as an objective source of information in the area of sustainability.

Flow Chart for IBU Verification Process

  • Development of the PCR documents
  • Creation of the declarations
  • Review and confirmation by independent third parties




  1. In the first step, if a draft for a PCR (Product Category Rule) – Document Part B is not yet available, it will be created by a product group forum consisting of experts and manufacturers, moderated by IBU. The product group will be defined and the characteristic environmental effects identified. The process for the quantification of these environmental effects and the evidence required to be submitted will be communicated to the prospective applicants. The PCR draft will then be reviewed by the Advisory Board for consistency between the product groups and the completeness of the requirements for the manufacturers. Following this, planners, developers, public authorities and the general public will have the opportunity to discuss the draft in an online forum and to contribute suggestions for improvement prior to release of the document by the SVR. If a PCR document already exists for the corresponding product group at the time the application is submitted, then this step will be omitted.
  2. In the second step, the EPD will be created on the basis of the guidelines in the PCR Guidance Text Part B. In order to be able to verify the results of the life cycle assessment, an additional  ‘background report’, based on PCR Part A, must also be drawn up. The underlying life cycle assessment model evolves from this, as do the applicable acceptance and allocation methods. For the preparation of the EPD document itself, an easy-to-use, web-based EPD online tool is available and accessible to all participants.
  3. In the third step, the EPD and the background report will be reviewed by the SVR-appointed verifier as an independent third party for compliance with the principles of ISO 14025 and EN 15804. After a review for completeness, plausibility, and consistency of data and calculations, a verification report will be compiled. Subsequently, the EPD will be published by the IBU. The Institut Bauen und Umwelt e.V. as program operator has no influence on the confirmation of the declaration, and merely publishes declarations released by the independent third parties. An EPD is valid for 5 years.
