Due to security reducing admission to the conference it was not possible for all speakers and invitees to enter the building and participate in this side event. Despite this, Delta Alliance was presented to a small crowd of delegates and press.

Keynote speaker Prof. Jan Sopaheluwakan from the Indonesian Institute of Sciences (LIPI), who was not permitted to enter the conference centre, presented his vision about an international delta network via a Skype connection from his accommodation in Copenhagen. Tineke Huizinga, the Dutch Vice Minister of Water and Transport, hailed the Delta Alliance initiative, stressing the importance of international cooperation among delta regions in the context of climate change.
