Unlike all the other groups in the European Parliament, the Greens/EFA have a co-presidency, i.e. two co-Presidents, and gender balance is always guaranteed. The Greens/EFA statutes specify that at least half of the Chairpersons and Vice-Chairpersons posts shall be held by women.

After the June 2009 elections, Daniel Cohn-Bendit (Europe Ecologie/Les Verts -France) and Rebecca Harms (Bündnis90/Die Grünen - Germany) were elected Co-Presidents of the group for the first half of the legislative period, i.e. till end of December 2011.
