The Extinction Solutions Index (ESI): A framework to measure solution efficiency to address biodiversity loss
Conservation efforts must start addressing the underlying drivers of biodiversity loss, rather than just the symptoms, and advance solutions that can protect biodiversity at scale and minimize extinction risk. To do so, we envision a framework to rank, evaluate and compare solutions for biodiversity loss—an Extinction Solutions Index (ESI). Inspired by Project Drawdown, which ranks and evaluates solutions to global climate change across different sectors and in different socioeconomic domains, the ESI seeks to evaluate, compare and rank the most effective and efficient innovations or interventions that would dramatically curb the sixth mass extinction while ensuring global human well-being. Developed in collaboration with One Earth, Project Drawdown, researchers at the University of Oxford, Re:wild, IUCN's Green Status of Species, Wildlife Conservation Society, and Adventure Scientists, the ESI is designed to evaluate, compare, and rank the most effective and efficient solutions to the escalating biodiversity crisis.
