Up to 2022 additional financial reporting on sustainability has been done on a voluntary basis by insurance companies. The reporting companies, usually larger groups, regularly involve actuaries in the corresponding preparation of information. Early in 2022 relevant institutions have started to prepare concrete financial reporting requirements at European level, which will become mandatory for insurance companies as well. Consultations have been underway since the end of March. From 2023, corresponding information will then have to be included in the notes to the annual reports. Quantitative information on sustainability will also be published. That will be the task of actuaries. The online training is intended to provide participants with basic information on mandatory sustainability reporting of insurance companies located in Europe. The main purpose is to speed up participants own activities.
