our most transparent sustainability report 2025.

With our 2025 Sustainability Report, we’re making ourselves transparent in the truest sense of the word – including taking a close look at the uncomfortable parts. Under the title “crystal clear. our most transparent sustainability report 2025.”, we deliberately put transparency front and center. 

Across more than 50 pages, we show where we stand – and where further action is needed. For the first time, we are voluntarily reporting in line with the European VSME standard for non-listed small and medium-sized enterprises. This brings more structure, enables deeper insights into key topics, and makes our sustainability efforts even more transparent and easier to understand.
