In July, we held an event in Ljubljana, Slovenia, in cooperation with Sustainaware and the Institute for Health and Environment. During the workshops and lectures, the participants actively addressed problems and searched for possible solutions that focused on sustainable development, good health and well-being, reducing inequalities and climate action. We also tackled the question of what role do young people, education, economy, infrastructure play in the world…? Together, we created the International Youth Climate Declaration, which we are proud to share here.
