This paper describes the Zoöp model, an organisational framework fostering regenerative relationships between humans and nonhumans. With escalating ecological crises, traditional anthropocentric decision-making requires a shift towards equitable, multispecies collaboration. The Zoöp model translates more-than-human theories into practical organisational strategies for sustainable futures. Using the Het Nieuwe Instituut (HNI) as a case study, this paper examines how the Zoöp model fosters regenerative actions within a European cultural institution. The model constructs participatory futures, embedding multispecies interests directly into organisational processes to address gaps in current sustainability efforts. By bridging organisational theory, environmental sustainability, and futures studies, the Zoöp model advocates for reparative, just systems that prioritise ecological health and multispecies well-being. This paper highlights the model's potential to promote a philosophical shift, recognising the intrinsic value of all living beings in decision-making processes.
