On-site Townhall Meetings offer an active discussion platform that is open to all interested conference participants. At Townhall Meetings, information is shared on new initiatives or opportunities of interest to a wide range of disciplines. This is often followed by an open discussion on the matter raised. Townhall Meetings are non-commercial, cannot be used for session extension, and cannot be organized by commercial enterprises.

Any registered on-site participant may organize a Townhall Meeting, which is subject to the approval by the Programme Committee Co-Chairs. Townhall Meetings will take place Monday–Tuesday and Thursday–Friday from 19:00 to 20:00 in lecture rooms of the congress centre. EGU does not provide any hybrid solutions for Townhall Meetings. Upon acceptance, the respective meeting will appear in the Townhall Meeting programme as a session. Conveners can then add public information to their Townhall Meeting using the convener tools. Commercial meetings are not allowed.
