Dietary changes towards healthier and more sustainable diets have been highlighted as one of the key strategies for simultaneously reducing the environmental pressures of the food system and the health risks of current dietary patterns. Although there is broad consensus on the long-term need for global dietary changes, much less information is available or accessible at the national level. This report is intended to fill this gap by distilling estimates of the impacts of dietary changes for Germany from a series of global modelling studies with regional detail. The estimates include analyses of the environmental impacts, costs, and policy implications of dietary change at the country level.
