Organisations sit at the intersection of land, sea, industry, trade and communities. How they understand their relationship with nature - and how they design, use and recover resources - has direct implications for resilience, operational efficiency, licence to operate and long-term value. This ThinkZero offering introduces two closely connected approaches: nature-based design and circularity. Through accessible concepts and a practical port example, participants will explore why nature and circularity matter, how expectations are evolving, and how ports can begin translating these principles into action.
