In a world full of change and challenges, client needs sometimes arise so quickly that the Drees & Sommer Group is unable to develop appropriate responses in a reasonable time. In such cases, Drees & Sommer expands its expertise through shareholdings. Affiliated companies make their expertise available to the Group and provide timely support to our clients.

In keeping with our aspirations and philosophy, the companies involved are all leaders in their fields. We work together with them as equals. In this way, the affiliates not only complement our service portfolio in an ideal way; like us, they work with enthusiasm to ensure our clients’ success.

Drees & Sommer and the former EPEA Internationale Umweltforschung GmbH joined forces on January 1, 2019. After five years of close partnership advising clients and investors, Drees & Sommer and Professor Dr. Michael Braungart have formally teamed up to create a new company under the name of EPEA GmbH – Part of Drees & Sommer. The objective of the combination is to establish Cradle to Cradle® design principles for the circular economy in all sectors of industry.
