To gain a better knowledge of the current situation regarding mirror group establishment in Europe, to identify challenges and levers for setting up a mirror group and to understand how existing operational groups work, the PREPSOIL project partners have worked on building an overview of existing mirror groups or structure with similar purposes. PREPSOIL organised a webinar on June, 2025 16th to share some of the results of this work and to discuss existing initiatives, with feedback from three countries. The presentation supports used during the webinar are available here. Authors of the presentations available here are: Teresa Pinto-Correia ("Mirror Groups: what are we talking about?") Flavien Poinçot, Line Friis Lindner, Tove Ortman and Amanda Matson ("PREPSOIL overview of Mirror Group establishment across Europe") Theresa Van Hoesel ("National implementation of the EU Mission Soil in Austria") Elina Nikkola ("Feedback from Finland") Aleksandra Perčin ("Feedback from Croatia") For more information and access to the recording, please visit: https://prepsoil.eu/events/soil-mission-mirror-groups-where-do-we-stand
