The Environment Agency of Luxembourg, together with the Environment Agencies of Austria, Switzerland, Germany and Liechtenstein, invite to an exchange of science and practice within the field of Green Finance. This year's conference "Goals, Actors and Levels - Ambitions and Effectiveness" aims to outline the current state of work of the green finance agenda, as well as to map its actors and levels, in order to discuss in more depth the level of implementation and challenges in this context. This year's fourth format will bring together important voices from science and practice, stimulating contributions will be looked at from different angles in subsequent panel discussions.
