Food waste represents a multifaceted challenge that entails financial cost, severe environmental impact, risks to food security, and deepening social inequality. Throughout the region, young people are concerned about these challenges but at the same time waste a significant amount of food in their home. This shows an important attitude-behaviour gap influenced not only by young people, but also by the food system around them. These guidelines were written with the input by young people aged 18-26 from Nordic-Baltic region to identify situations when food is wasted and to find ways to help young households waste less food. Preparation of the guidelines allowed to crystalize priorities, identify best practice examples, and highlight specific recommendations for all stakeholders that young people would see as most helpful on their journey to reducing household food waste.
