Due to its great success in March 2023 and to some requests for a re-run of our session, we are pleased to offer the content again: Methodologies on Climate Scenario Analysis for insurers have been developing rapidly over the last years. Ongoing attention by all stakeholders, pilot exercises all over the world and a substantial increase in awareness towards climate-related risks have incited insurers to develop and refine their stress testing capabilities on climate-related risks. In this session, we will talk about the latest developments and challenges for maturing climate risk stress testing frameworks for insurers. We will talk about the set-up of physical and transition risk scenarios, common techniques for selecting, merging, and enhancing suitable scenario variables, as well as practical approaches for impact quantification and their difficulties in application.
