Abstract Unhealthy diets are a key risk factor for disease and premature death in Europe and worldwide. Moreover, the food system is a key driver behind many processes of global environmental change, including climate change, biodiversity and habitat loss. Accordingly, calls have been made for a transformation of the global food system. This requires action in a variety of policy fields and on all political levels. The creation of healthy food environments through public sector action on a national and regional level is an essential aspect of this. The Food Environment Policy Index (Food-EPI) is an established methodological framework for the assessment, analysis and benchmarking of public policies influencing food environments, developed by INFORMAS, a global network of public-interest organizations. In this 90 min workshop, we will present the approach used by the Food-EPI and results from the implementation of the Food-EPI on the EU level and in Germany, the Netherlands, Norway and Poland, followed by a joint discussion of lessons learnt and key policy implications. The Food-EPI has two components (policy and infrastructure support domains) covering a total of 13 domains and 47 indicators. For each indicator, policies and actions are compiled and benchmarked against international best practice by independent experts and stakeholders. Based on this assessment, priority actions for reform are identified. Policy makers and independent public health and nutrition experts are involved in key steps of the process to ensure policy relevance and impact. Key messages The systematic assessment and benchmarking of nutrition policies helps to identify priority actions to improve food environments and enhances government accountability for public health. Both on the EU level and in EU member states, governments have taken action to support healthy food environments, but considerable room for improvement remains.
