Until January 2002, the European Forum was placed within the secretariat of the Party of European Socialists (PES) in Brussels. Since then, the coordination and daily work is being done from the Netherlands. PRO International is responsible for the coordination of the Forum and the implementation of the working program. PRO International is a new merger foundation from Foundation Max van der Stoel (FMS) and International Foundation GroenLinks (IFG), who merged in 2026.
