The Partnership for Resilience and Preparedness (PREP) was formed in 2016 around a simple principle — the belief that everyone should have access to actionable climate, physical and socioeconomic data. PREP brings together over 30 partners from leading government agencies, research institutions and technology companies. In 2018, the partnership launched PREPdata, a free, open source data platform that provides the accessible, curated data that decision-makers need to analyze vulnerability and build climate resilience.
