Working Groups (WG) are thematic bodies that support the Parties to the Carpathian Convention in implementing key provisions of the Convention based on its thematic topic.

WGs are composed of the National Focal Points for the Carpathian Convention and/or persons nominated by them. In intimate forums, WGs discuss particular issues that need to be analyzed by experts before the main organs will decide on them. WG meetings are open to observers, and depending on the thematic focus of the WG, representatives from partner organisations and NGOs also attend to contribute their expertise.
