The Earth Charter has been known in Hungary since at least 2007 when the Balkan and Black Sea Circle Consortium Conference (BBCC) was held in May of that year. EC International actively participated in this annual conference held at the University of Debrecen, Hungary. A presentation was made on the use of the Earth Charter as a framework for ESD.

In 2012-13, the Andrassy Catholic Business Academy in Hungary and Avonbourne College and Academy began collaboration on an international project to bring Earth Charter values and principles into the whole-school curriculum. The first round of this project was completed in 2014 and a case study was published by Earth Charter International in “The Heart of the Matter: Infusing Sustainability Values in Education”, a publication submitted for the end of the UN Decade for ESD.
