Funded by the German Federal Ministry for the Environment, Nature Conservation, Nuclear Safety and Consumer Protection (BMUV) and the Federal Ministry for Economic Cooperation and Development (BMZ), the new version of the Climate Risk Book (CR-SB), developed by Eurac's Research Centre for Climate Change and Transformation together with GIZ, UNU-EHS, GeoSphere Austria and IIASA, was launched during the Adaptation Futures 2023 conference. The book provides a conceptual framework for a comprehensive climate risk assessment (CRA) along with modular guidance, divided into eight modules, on how it can be carried out. The guidelines have been updated to align with the latest IPCC report (AR6), introducing external risk factors, impact/risk cascades and systemic risks, and a new chapter on how CRAs inform Climate Risk Management (CRM).
