Civil society, governments and the private sector are in strong agreement that conservation and development need to go hand in hand. The International Union for Conservation of Nature (IUCN) promotes the mitigation hierarchy approach, with a net gain target for biodiversity in all landscape planning. By applying IUCN’s Review Protocol on biodiversity net gain at different sites, both Newmont Corporation (Newmont) and IUCN are on a journey to explore the challenges and opportunities of scaling up such approaches across the private sector.
