Collecting the necessary data for the EPD, calculating the life cycle assessment and creating an EPD that conforms to the norms is the responsibility of the manufacturer. Normally, if the appropriate know-how is unavailable at his/her own company, the manufacturer will hire an experienced life cycle assessment service provider for support with the creation of the EPD. A list of companies and experts who have already successfully taken over these kinds of projects for EPDs with the IBU may be found in our list of cooperations in section 2 – LCA Practitioners.
