Buhck-Stiftung

What Buhck-Stiftung does

Buhck-Stiftung is a private foundation under German civil law (Stiftung bürgerlichen Rechts), founded in 1999 by Bergedorf entrepreneur Carsten Buhck and headquartered in Reinbek, Schleswig-Holstein with its registered seat in Hamburg-Bergedorf. The foundation initiates and funds approximately 60 regional projects in Hamburg-Bergedorf and the adjacent counties of Stormarn and Herzogtum Lauenburg, organized around two core focus areas: environmental education (e.g., Draußenschule, greenKIDS, NaturEntdecker, KITA21, Recycling-Lab) and social integration of youth (e.g., Jobpaten, HipHop Academy, Stadtteilmütter, Salon5, KinderHelden). It also convenes the Hamburger Umweltstiftungs-FORUM networking platform for Hamburg-based environmental foundations.

The foundation does not sell products or services. Its revenue model is donations-based: it is funded by donations derived from the profits of the Buhck Group (a German environmental services company), supplemented by private donations, with the share of profits governed by a verbal agreement. The foundation is steered by an independent six-member supervisory board (Kuratorium) chaired by Dr. Jörg Verstl, while the executive board (Vorstand) consists of Bianca and Britta Buhck, the founder's daughters-in-law, who assumed leadership following Carsten Buhck's death in 2013. Programmatic leadership is split between Tanja Ebbecke (environmental education) and Angela Roggendorf (integration). The organization employs 5 staff and relies on 600+ volunteers and multipliers, reaching approximately 7,000 children and young people annually across 100+ schools and kindergartens.

The foundation's strategic intent is to combine environmental education and social integration within a single regional footprint, with the board personally visiting and monitoring each funded project. Its competitive position rests on 25 years of regional network-building, partnerships with other foundations (Loki Schmidt Stiftung, S.O.F., Stiftung Natur im Norden, Körber-Stiftung, Deutsche Wildtier Stiftung), and integration into the Engagierte Stadt Bergedorf civic engagement network. Multiple projects have received external recognition, including UN Decade on Biodiversity status for Draußenschule (2019), the German Multimedia Award mb21 (2023), and TalentAward Ruhr (2022).
