Plant-Based Universities is a fast-growing, volunteer-led movement making universities plant-based across Europe. Lucas and Klaas Temmerman explore how PBU's success stems from empowering a diverse volunteer base, including non-vegans, through autonomy, trust, and a climate-focused strategy. This session provides a deep dive into the "PBU model": building resilient structures, leveraging multi-issue approaches (climate and justice) to create systemic change, and mobilizing beyond the traditional boundaries of the animal rights movement.
