This document presents a summary of effective policy design measures and practices identified at a workshop of the European Commission's Working Group Schools: Learning for Sustainability that took place at the World Environmental Education Congress (WEEC) in Prague on 16 March 2022. The hybrid event was open to members of the working group (who joined in-person and online) as well as WEEC participants in Prague. The policy brief has been informed by a presentation from the European Commission at the start of the workshop which gave an overview of the policy landscape in the EU regarding learning for sustainability. A panel discussion with working group representatives from Czech Republic, Cyprus and Hungary as well small group work engaged members and participants from the WEEC in refining and extending the core messages arising out of this initial presentation. The workshop centred on what constituted good policy design as well as how to ensure this is translated into effective implementation.
