D2.3 Guidelines on loss data: A Framework for Harmonized and Interoperable Climate-Related Economic Loss Data

The document introduces a methodology for recoding, storing and sharing property insurance loss data related to climate-induced natural hazards. For efficient data sharing across organizations, and with European and international bodies, the document suggests a core set of fields that should be included in any operational disaster loss database. To manage the complexities of loss recording in various national contexts, it advocates for simplified aggregate figures using a standardized nomenclature and data formats aligned with the Risk Data Hub1 portal (part of the European Commission Disaster Risk Management Knowledge Centre). It aims to support stakeholders, including insurance companies, municipalities, policymakers, and data managers, in standardizing the way loss data is recorded and exchanged. 1 Accessed 31.10.2025
