The theme "One world, Infinite Solutions" will explore how you can turn your passion into a way of changing the environment for the better. This year, METGREEN will offer a wide variety of workshops and speakers from all imaginable professions; even if you never thought that they have anything to do with the environment! No matter whether your passion is activism, politics, science, journalism, entertainment and media, art, sport or anything else; we invite you all to take part in METGREEN-23!
