The European Green Deal is a package of strategic initiatives that aims to put the EU on the path to a green transition, with the ultimate goal of achieving climate neutrality by 2050. It supports the transformation of the EU into a fair and prosperous society with a modern and competitive economy. This project aims to transfer the themes of sustainability into a school context through an interdisciplinary, fun and innovative educational path. The founders participated to Summer School inside the Erasmus Project "EU - The Green Wave: a Jean Monnet Action inspired by Claude Monet" organized by EEPEK in Thessaloniki from 19 to 19 August 2024. Teachers have the aim of spreading and defending the values of sustainability for a better world.
