Global food demand is projected to increase by 70% till 2050 and providing adequate nutrition while minimizing the food systems impact on the environment is a massive challenge. Agriculture and food production are arguably the sectors with the largest impact on resource use and environmental sustainability. In addition, diet related diseases are the largest contributor to both the human deaths and disability around the world. Positive dietary changes such as shift to foods with low environmental impact and high nutrient content, can go a long way in achieving global food sustainability and therefore contribute significantly towards improving global nutritional & health standards and reducing overall anthropogenic environmental footprint. However, methods to quantify and compare nutritional quality of different diets are in nascent stages of development and studies assessing nutrition-environment trade-offs are almost non-existent. Life cycle assessment (LCA) is increasingly used to evaluate the ‘cradle to grave’ environmental impacts associated with products and processes but its results often suffer from huge uncertainty, thus limiting their application at the national policy level. Apart from impacts occurring domestically, the environmental impacts ‘hidden’ in imported products must be included in any national accounting. Global scale studies assessing the sustainability of diets through multiple nutritional and environmental indicators is therefore needed to identify the country-specific areas of improvement. The aim of this project is to develop a novel framework combining multi-indicator environmental & ecosystem impact assessment and diet level nutritional quality assessment methodologies to evaluate the sustainability of national food systems and develop evidence base to design nation-specific dietary transformation pathways. The project will leverage global food consumption, trade and life cycle assessment (LCA) databases. The project combines Module-1 (expanding the knowledge base) and Module-4 (business application) of the call. Addressing Module-4, through data exchange and collaboration with Switzerland’s biggest food retailer ‘Migros’, an in-depth analysis of factors identified as contributing the most to Swiss food consumption and trade impacts will be carried out to assess the nutrition and environmental sustainability opportunities and concrete options for action.
