At the kind invitation of the Estonian Environment Agency, the 3rd ACCORD All Staff Workshop was organised as an hybrid event over 5 full days, from Monday 27 to Friday 31 March 2023, in Tallinn (Estonia) in the conference rooms at the Tallinn Nordic Hotel Forum - Tallinna südames.

The ASW did run smoothly: WARM CONGRATULATIONS to the Estonian hosts

• 198 registered participants of which 90 on site,
• in addition 32 remote participants just popped up without registering,
• 65 to 95 remote participants during the sessions,
• 8 sessions plus the opening & closing sessions, and 3 side-meetings,
• 78 speakers including 19 poster presenters,
• video-recording: 30 hours. |
  A big THANK YOU to the participants, in-situ or remotely, who made this All Staff Workshop a real success.
  And a big PERSONAL THANK YOU from the 1st CSS ACCORD for all the touching attentions on the occasion of the announcement of her upcoming departure (see photos).
