The European Commission is calling for promising and implemented good practices, i.e. relevant policies or interventions focusing on mental health promotion, prevention, detection and intervention – including those that respond to the challenges posed by climate change. The EC, in cooperation with Member States, will support not only the implementation of the practices, but also the development of guidelines on early detection and intervention and screening of vulnerable groups. Governmental and non-governmental actors are invited to submit proposals for best and promising practices through EU Good Practices Portal by Friday 29 September (midnight CET), after consultation with manual for the submitter.
