The founding States
Twelve European States signed the constituent act in 2007: France, Switzerland, Germany, Italy, Spain, Belgium, the Netherlands, Portugal, the United Kingdom, Sweden, Greece and Austria. They laid the foundations for the functioning of the Organisation and hosted its first meetings.
France hosts Headquarters in Paris, and Switzerland the Geneva liaison office.



Accessions in 2008 and 2009
In 2008, three States joined the Organisation: Ireland, Denmark and Norway. In 2009, Finland, Poland and Czechia followed. These accessions extended the Organisation towards Northern and Central Europe.
Each of these States has designated a national focal point, who takes part in the annual meetings.
Accessions from 2010 to 2012
Hungary and Romania joined in 2010; Bulgaria, Croatia and Luxembourg in 2011; Slovakia and Slovenia in 2012. With the latter, the region reached 25 States, a total that has not changed since.
The States of this period often benefited from technical cooperation programmes to align their procedures.
