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.
