In an era of interconnected crises – from climate change to biodiversity loss – transformative solutions require collaboration at scale. This chapter explores how public-private-philanthropic partnerships (4Ps) can unlock new funding models, amplify impact, and drive systemic change. It introduces pooled funds as a game-changing approach, demonstrating how aggregating resources across sectors can mobilize capital for high-impact initiatives.
