The "EKOS" Association for Education for Sustainable Development was established in Rzeszów in August 2011 on the initiative of Jerzy Węgrzynowski.

This institution promotes the idea of sustainable development, cyclically organising international youth exchanges, language camps, workshops, seminars and conferences both for pupils and teachers on international level.

The impetus for establishing the "EKOS" Association were differences in understanding and implementing the principles of sustainable development in social and economic life in Germany and Poland.

People representing university, school and local government communities involved to cooperate in the work of the association. All members are people with great knowledge, rich professional biographies and - most importantly - devoted to the main idea, which is the dissemination of knowledge about sustainable development in Subcarpathian Region (Podkarpackie) and Poland.
