The SiE project aims to reduce binge drinking and associated harms in young people, through the development of locally tailored community based interventions designed to tackle heavy episodic drinking in different drinking environments. The project is based on the original STAD programme in Sweden, which combines three core components (community mobilisation, bar staff training in responsible beverage service, and stricter law enforcement) aiming to tackle alcohol-related harms in nightlife environments. The SiE project focuses on transferring the STAD model to four drinking settings: nightlife; festivals; public environments (e.g. streets, parks and beaches); and, private environments (e.g. home drinking). The project involves the development and piloting of interventions to tackle heavy episodic drinking for one of these settings in seven pilot areas in: the Czech Republic, Germany, the Netherlands, Slovenia, Spain, Sweden and the United Kingdom (UK).
