Implementing sustainable diets in Europe


The general goal of the SUSDIET  project was to (i) assess health and environmental impacts of current and alternative diets in Europe, (ii) better understand consumers' preferences for food, (iii) assess the effects of policy instruments supporting more informed choices, or affecting the market environment. The SUSDIET approach was multi-disciplinary, encompassing researchers in consumer studies, environmental science, economics, nutrition, and public health. In the first part, a the comparison of dietary patterns was observed and it was determined which adjustments in consumers' diets would have to be prioritized in order to improve public health and environmental impact. The second part focused on consumers' motivations and preferences in relation to sustainable food consumption: What are major barriers, what's the effectiveness of different message characteristics in persuading consumers to change their decisions,...

The third part of the project focused on the effects of policies aiming to influence food choices: the impact of food labels on consumers' trade-offs, joint vs. separated labelling of health and environmental dimensions, analyzed policies which modify the relative prices of the different food groups (e.g. carbon tax).
