In 17 countries of the IUCN European region covering the European continent, North and Central Asia and the EU overseas territories, IUCN Members are organized in National Committees.

The aim of these Committees is to facilitate cooperation among Members and between Members and the IUCN Secretariat and other actors in the Union. They play an important role in coordinating efforts of the IUCN constituency at the national level. In each country where they have been established, Committees represent an important interlocutor for national nature policies and issues.
