The Nature Conservancy (TNC) is awarded the LUI Che Woo Prize for Sustainability for its long-standing and well-recognised successful efforts to “conserve the lands and waters on which all life depends”. Using a holistic and science-based approach, TNC protects, restores and maintains whole ecosystems, including their bio-diversity, through conservation, re-forestation and tree-planting, the promotion of new national parks, and the use of land preservation techniques such as conservation easements and debt for nature swaps.
